PROBIOTICI
Certain probiotic organisms appear to enhance innate immunity (particularly
phagocytosis and natural killer cell activity), but they seem to have a less
pronounced effect on acquired immunity.
Studies show improved vaccination responses in individuals taking.
Recent systematic reviews and meta-analyses confirm that probiotics or
prebiotics (these are usually non-digestible oligosaccharides that act as
fuels for some types of bacteria enhancing their growth; many probiotics are
bifidogenic) enhance the antibody response to seasonal influenza
vaccination in adults.
The studies with probiotics have most often used lactobacilli or bifidobacteria.
Upon virus attack in epithelial cells, probiotic bacteria have a crucial role in
antiviral immunity via modulation of host immunological responses,
including activation of NK cells, balancing Th1/Th2-mediated immunity,
production of inflammatory cytokines, and specific antibodies
Activation of immune response leads to the differentiation of CD8+ T-lymphocytes
into cytotoxic T-lymphocytes, capable of destroying virus-infected cells. Next,
CD4+ T-lymphocytes cells can differentiate into Th1, which activates
phagocytosis through NK cells and macrophages, promoting pathogen killing.
Further, CD4+ cells differentiate into Th2 cells, which induce B-cells proliferation,
resulting in the production of antibodies that may play a crucial role in combating
coronavirus proliferation. Thus, probiotic bacteria may catalyze useful
immune responses and improve immune homeostasis in coronavirus-
infections.
Fig. 2. Schematic depiction of putative mechanisms by which probiotics may help manage coronavirus infection. (A) Probiotic bacteria
can hinder the adsorption process via directly binding to the virus and inhibiting entry into epithelial cells. (B) Binding of probiotic
bacteria to the epithelial surface can cause steric hindrance and block the virus's attachment to the host cell receptor. (C) Probiotic
bacteria releases antimicrobial substances (such as bacteriocins, biosurfactants, lactic acid, hydrogen peroxide, nitric oxide, organic
acids) and intestinal mucins from mucosal cells, which can effectively inhibit virus proliferation. (D) Virus neutralized by secretory
antibodies like IgA. (E) Upon virus attack in epithelial cells, probiotics mediate their antiviral effects by eliciting immune responses by
activating macrophages and dendritic cells. (F) Activation of immune response leads to differentiating CD8+ T lymphocytes into CTLs,
capable of destroying virus-infected cells. (G) CD4+ T lymphocytes cells differentiate into Th1, which activates phagocytosis through NK
cells and macrophages, promoting pathogen killing. (H) CD4+ cells differentiate into Th2 cells, which induce B-cells' proliferation that
produces antibodies like IgA, IgG, and IgM. CTLs, cytotoxic T-lymphocytes; Th1, T-helper cells type 1.
Oksidativni stres
Oxidative stress is a condition that reflect an imbalance between biological defensive and aggressive system,
mediated by excessive production of reactive oxygen species (ROS), e.g., O2− (superoxide radical), ⋅OH (hydroxyl
radical), and H2O2 (hydrogen peroxide), in which there is an inability of the antioxidant mechanisms to neutralize
them.
This process results in toxic effects and alterations of the normal redox state, which is associated with cellular
damage and lipid peroxidation
Studies have shown that inflammation and oxidative stress are interconnected phenomena, which are involved in pathological
conditions as cardiovascular, kidney, liver disease, and cancer. In this way, during inflammatory events occur exacerbated
production of ROS in the damaged inflammatory tissue, which can stimulate and had a critical role in the signaling pathway for
inflammatory mediators production, such as proinflammatory cytokines and chemokines, resulting in inflammatory cell
migration.

• History of Phytochemicals
• Phytochemicals exist as long as plants exist
but we only know about hundred years
about their existence. Medicinal plants are
traditionally used all over the world. It is
likely that the knowledge of traditional
medicine developed through trial and error
over many centuries.
• The Chinese have the oldest medicine
system. More than 5000 years ago, the
Chinese based their medicine on the
influence of yin and yang, and on the five
elements. The earliest records about herbal
medicine dates back to 2800 BC when the
Chinese emperor Shen Nong wrote the
text The Great Native Herbal.
One of the first written texts covering the use of
ginseng as a medicinal herb was the Shen
Nong Pharmacopoeia, written in
China in 196 AD.
In his Compendium of Materia Medica herbal of
1596, Li Shizhen described ginseng as a
"superior tonic". However, the herb was not used
as a "cure-all" medicine, but more specifically as
a tonic for patients with chronic illnesses and
those who were convalescing.
Emperor Shen-Nung was the second of China's mythical emperors (3500-2600 BCE).
Widely considered the father of Chinese medicine, he catalogued over 365 species of medicinal
plants which he personally tasted. Through his treatise ‘Shen Nung Benchau Jing’, we relive
Emperor Shen-Nung's contribution to urology with reference to his management of erectile
dysfunction. Time-related sources in medical and historical literature were reviewed, including the
‘Shen Nung Benchau Jing’ (The medicine book of Emperor Shen-Nung), archives and
manuscripts at the Wellcome History of Medicine Collection, the Royal Society of Medicine,
London, The Hong Kong Museum of Medical Sciences, and The Museum of Medical History,
Shanghai, China. Chinese traditional herbal medicine began approximately 5000 years ago.
Agricultural clan leader, Emperor Shen-Nung, was said to have a ‘crystal-like belly’ to watch the
reactions in his own stomach of the herbs he collected. Ginseng was among of Shen Nung's
contributions to herbal medicine
Hippocrates (460-377 BC) and Aristotle (384-322 BC) introduced the
herbal medicine from India and Egypt to Europe.
The Greek physician Dioscorides wrote the book De Materia Medica in the
first century AD.
https://en.wikipedia.org/wiki/De_materia_medica
De materia medica (Latin name for the Greek work Περὶ ὕλης ἰατρικῆς, Peri hulēs iatrikēs, both meaning
"On Medical Material") is a pharmacopoeia of medicinal plants and the medicines that can be obtained from
them.
The five-volume work was written between 50 and 70 CE by Pedanius Dioscorides, a Greek physician in
the Roman army.
It was widely read for more than 1,500 years until supplanted by revised herbals in the Renaissance, making
it one of the longest-lasting of all natural history books.
The work describes many drugs known to be effective,
including aconite, aloes, colocynth, colchicum, henbane, opium and squill.
In all, about 600 plants are covered,
along with some animals and mineral substances,
and around 1000 medicines made from them
.
De materia medica was circulated as illustrated manuscripts, copied by hand, in Greek, Latin and Arabic
throughout the mediaeval period. From the sixteenth century on, Dioscorides' text was translated into Italian,
German, Spanish, and French, and in 1655 into English. It formed the basis for herbals in these languages
by men such as Leonhart Fuchs, Valerius Cordus, Lobelius, Rembert Dodoens, Carolus Clusius, John
Gerard and William Turner. Gradually these herbals included more and more direct observations,
supplementing and eventually supplanting the classical text.
Several manuscripts and early printed versions of De materia medica survive, including the
illustrated Vienna Dioscurides manuscript written in the original Greek in sixth-century Constantinople; it was
used there by the Byzantines as a hospital text for just over a thousand years. Sir Arthur Hill saw a monk
on Mount Athos still using a copy of Dioscorides to identify plants in 1934.

best diet to support the immune system is one with a diverse and
varied intake of vegetables, fruits, berries, nuts, seeds, grains and
pulses along with some meats, eggs, dairy products and oily fish.
This diet is consistent with those regarded as generally healthy and
is consistent with current dietary guidelines.
Such a diet would preclude too much processed and ‘junk’ food and
excessive amounts of saturated fat and sugar.
Nutrition, immunity and COVID-19
by Philip C Calder
A vitamin Vit. A (retinol, retinal, retinoic acid,
retinyl palmitate, beta-carotene)
Karotenoidi
Vitamin A is important for normal differentiation of epithelial tissue and for immune cell maturation and
function. Thus,vitamin A deficiency is associated with impaired barrier function, altered immune responses
and increased susceptibility to a range of infections.
Many aspects of innate immunity, in addition to barrier function, are modulated by vitamin A and its
metabolites. Vitamin A controls neutrophil maturation and in vitamin A deficiency blood neutrophil
numbers are increased, but they have impaired phagocytic function. Therefore, the ability of
neutrophils to ingest and kill bacteria is impaired.
Vitamin A also supports phagocytic activity and oxidative burst of macrophages, so promoting
bacterial killing. Natural killer cell activity is diminished by vitamin A deficiency, which would impair antiviral
defences.
The impact of vitamin A on acquired immunity is less clear and may depend on the exact setting and the
vitamin A metabolite involved. Vitamin A controls dendritic cell and CD4+ T lymphocyte maturation and
its deficiency alters the balance between T helper 1 and T helper 2 lymphocytes.
Studies in experimental model systems indicate that the vitamin A metabolite 9-cis retinoic
acid enhances T helper 1 responses. Retinoic acid promotes movement (homing) of T lymphocytes to the
gut-associated lymphoid tissue. Interestingly, some gut-associated immune cells are able to synthesise
retinoic acid. Retinoic acid is required for CD8+ T lymphocyte survival and proliferation and for normal
functioning of B lymphocytes including antibody generation. Thus, vitamin A deficiency can impair the
response to vaccination
In support of this, vitamin A-deficient Indonesian children provided with vitamin A showed a higher antibody
response to tetanus vaccination than seen in vitamin A-deficient children.
Vitamin A deficiency predisposes to respiratory infections, diarrhea and severe measles. Systematic
reviews and meta-analyses of trials in children with vitamin A report reduced all-cause mortality, reduced
incidence, morbidity and mortality from measles and from infant diarrhoea, and improved symptoms in acute
pneumonia.

B complex
B vitamins are involved in intestinal immune regulation, thus contributing
to gut barrier function.
Folic acid deficiency in animals causes thymus and spleen atrophy, and
decreases circulating T lymphocyte numbers. Spleen lymphocyte
proliferation is also reduced but the phagocytic and bactericidal capacity of
neutrophils appears unchanged.
In contrast, vitamin B12 deficiency decreases phagocytic and bacterial
killing capacity of neutrophils, while vitamin B6 deficiency causes thymus
and spleen atrophy, low blood T lymphocyte numbers and impaired
lymphocyte proliferation and T lymphocyte-mediated immune responses.
Vitamins B6 and B12 and folate all support the activity of natural killer cells and
CD8+ cytotoxic T lymphocytes, effects which would be important in antiviral
defence.
Patients with vitamin B12 deficiency had low blood numbers of CD8+ T
lymphocytes and low natural killer cell activity.
In a study in healthy older humans, a vitamin B6-deficient diet for 21 days
resulted in a decreased percentage and total number of circulating
lymphocytes, and a decrease in T and B lymphocyte proliferation and IL-2
production.61 Repletion over 21 days using vitamin B6 at levels below those
recommended did not return immune function to starting values, while
repletion at the recommended intake (22.5 μg/kg body weight per day, which
would be 1.575 mg/day in a 70 kg individual) did. Providing excess vitamin B6
(33.75 μg/kg body weight per day, which would be 2.362 mg/day in a 70 kg
individual) for 4 days caused a further increase in lymphocyte proliferation and
IL-2 production.

• Furthermore, it has been reported that vitamin C
affects lung function by influencing various
prostanoids in lung tissues and that vitamin C
deficiency increases the level of
bronchoconstrictor Prostaglandin F2α (PGF2α).
• In guinea pigs on a diet deficient in vitamin C, an
increase in airway hyper-responsiveness to
histamine was observed and in isolated guinea
pig trachea smooth muscle, vitamin C decreased
the contractions caused by PGF2α, histamine and
carbamylcholine.

• The role of vitamin C in prostaglandin
metabolism has also been strengthened by
another study in humans, where a 2-week
vitamin C diet reduced post-exercise increase in
the urinary markers for the bronchoconstrictors
leukotriene C4–E4, 9a and 11b-PGF2 as well as
exhaled nitric oxide when compared to placebo
and usual diet.
• Furthermore, another study reported that in vivo
administration of vitamin C modulates T cell
proliferation and cytokine secretion, associating
vitamin C with the immune response.
Vitamin C is required for collagen biosynthesis and is vital for maintaining
epithelial integrity.
It also has roles in several aspects of immunity, including leucocyte
migration to sites of infection, phagocytosis and bacterial killing, natural
killer cell activity, T lymphocyte function (especially
of CD8+ cytotoxic T lymphocytes) and antibody production.
Jacob et al. showed that a vitamin C-deficient diet in healthy young adult
humans decreased mononuclear cell vitamin C content by 50% and
decreased the T lymphocyte-mediated immune responses to recall
antigens.
Vitamin C deficiency in animal models increases susceptibility to a variety
of infections.
People deficient in vitamin C are susceptible to severe respiratory
infections such as pneumonia. A meta-analysis reported a significant
reduction in the risk of pneumonia with vitamin C supplementation,
particularly in individuals with low dietary intakes
Vitamin C supplementation has also been shown to decrease the duration
and severity of upper respiratory tract infections, such as the common
cold, especially in people under enhanced physical stress.

Vit. D
Vit. D
The active form of vitamin D (1,25-dihydroxyvitamin D3) is referred to here as vitamin D.
Vitamin D receptors have been identified in most immune cells and some cells of the
immune system can synthesise the active form of vitamin D from its precursor, suggesting
that vitamin D is likely to have important immunoregulatory properties.
Vitamin D enhances epithelial integrity and induces antimicrobial peptide (eg, cathelicidin)
synthesis in epithelial cells and macrophages,directly enhancing host defence.
However, the effects of vitamin D on the cellular components of immunity are rather
complex. Vitamin D promotes differentiation of monocytes to macrophages and increases
phagocytosis, superoxide production and bacterial killing by innate immune cells.
It also promotes antigen processing by dendritic cells although antigen presentation may
be impaired. Vitamin D is also reported to inhibit T-cell proliferation and production of
cytokines by T helper 1lymphocytes and of antibodies by B lymphocytes, highlighting the
paradoxical nature of its effects.
Effects on T helper 2 responses are not clear and vitamin D seems to increase number of
regulatory T lymphocytes. Vitamin D seems to have little impact on CD8+ T lymphocytes
A systematic review and meta-analysis of the influence of vitamin D status
on influenza vaccination (nine studies involving 2367 individuals) found
lower seroprotection rates to influenza A virus subtype H3N2 and to
influenza B virus in those who were vitamin D deficient.
adults showed an independent inverse association between serum 25(OH)-
vitamin D and recent upper respiratory tract infection.
Other studies also report that individuals with low vitamin D status have a
higher risk of viral respiratory tract infections.
Supplementation of Japanese schoolchildren with vitamin D for 4 months
during winter decreased the risk of influenza by about 40%.85 Meta-
analyses have concluded that vitamin D supplementation can reduce the
risk of respiratory tract infections

Vit. E
In laboratory animals, vitamin E deficiency decreases lymphocyte
proliferation, natural killer cell activity, specific antibody production
following vaccination and phagocytosis by neutrophils.
Vitamin E deficiency also increases susceptibility of animals to infectious
pathogens.
Vitamin E supplementation of the diet of laboratory animals enhances
antibody production, lymphocyte proliferation, T helper 1-type cytokine
production,natural killer cell activity and macrophage phagocytosis.
Vitamin E promotes interaction between dendritic cells and CD4+ T
lymphocytes. There is a positive association between plasma vitamin E and
cell-mediated immune responses, and a negative association has been
demonstrated between plasma vitamin E and the risk of infections
in healthy adults over 60 years of age.
There appears to be particular benefit of vitamin E supplementation for the
elderly.
Studies by Meydani et al94 95demonstrated that vitamin E supplementation
at high doses (one study used 800 mg/day and the other95 used doses of
60, 200 and 800 mg/day) enhanced T helper 1 cell-mediatedimmunity
(lymphocyte proliferation,IL-2 production) and improved vaccination
responses, including to hepatitis B virus.
Supplementation of older adults with vitamin E (200 mg/day) improved
neutrophil chemotaxis and phagocytosis, natural killer cell activity and
mitogen-induced lymphocyte proliferation.
Secondary analysis of data from the Alpha-Tocopherol,Beta Carotene
Cancer Prevention Study identified that daily vitamin E supplements for 5
to 8 years reduced the incidence of hospital treated, community-acquired
pneumonia in smokers.

Iron
Iron deficiency induces thymus atrophy, reducing output of naive T lymphocytes,
and has multiple effects on immune function in humans.
The effects are wide ranging and include impairment of respiratory burst and
bacterial killing, natural killer cell activity, T lymphocyte proliferation and
production of T helper 1 cytokines.
T lymphocyte proliferation was lower by 50% to 60% in iron-deficient than in iron-
replete housebound older Canadian women.These observations would suggest a
clear case for iron deficiency increasing susceptibility to infection.
There are different explanations for the detrimental effects of iron administration
on infections. First, iron overload causes impairment of immune function.Second,
excess iron favours damaging inflammation. Third, micro-organisms require iron
and providing it may favour the growth of the pathogen. Perhaps for the latter
reasons several host immune mechanisms have developed for withholding iron
from a pathogen.

Zinc inhibits the RNA polymerase required by RNA viruses, like
coronaviruses, to replicate,suggesting that zinc may play a key role in host
defence against RNA viruses.
In vitro replication of influenza virus was inhibited by the zinc ionophore
pyrrolidine dithiocarbamate, and there are indications that zinc might inhibit
replication of SARS-CoVs in vitro.
In addition, as discussed by Read et al, the zinc-binding metallothioneins
seem to play an important role in antiviral defence.
Zinc deficiency has a marked impact on bone marrow, decreasing the number
immune precursor cells, with reduced output of naive B lymphocytes and causes
thymic atrophy, reducing output of naive T lymphocytes. Therefore, zinc is
important in maintaining T and B lymphocyte numbers.
Zinc deficiency impairs many aspects of innate immunity,including
phagocytosis, respiratory burst and natural killer cell activity.
Zinc also supports the release of neutrophil extracellular traps that capture
microbes.There are also marked effects of zinc deficiency on acquired
immunity. Circulating CD4+ T lymphocyte numbers and function (eg, IL-2
and IFN-γ production) are decreased and there is a disturbance in favour of
T helper 2 cells.
Likewise, B lymphocyte numbers and antibody production are decreased in
zinc deficiency. Zinc supports proliferation of CD8+ cytotoxic T
lymphocytes, key cells in antiviral defence.
Many of the in vitro immune effects of zinc are prevented by zinc chelation.
Moderate or mild zinc deficiency or experimental zinc deficiency in humans
result in decreased natural killer cell activity, T lymphocyte proliferation, IL-
2 production and cell-mediated immune responses which can all be
corrected by zinc repletion.
Zinc supplementation (30 mg/day) increased T lymphocyte proliferation in
elderly care home residents in the USA, an effect mainly due to an increase
in numbers of T lymphocytes.
The wide ranging impact of zinc deficiency on immune components is an
important contributor to the increased susceptibility to infections,
especially lower respiratory tract infection and diarrhoea, seen in zinc
deficiency.

Copper itself has antimicrobial properties. Copper supports neutrophil,

Copper deficiency in animals impairs a range of immune functions and

studies show that subjects on a low copper diet have decreased
lymphocyte proliferation and IL-2 production, with copper administration
reversing these effects.

Selenium deficiency in laboratory animals adversely affects several
components of both innate and acquired immunity, including T and B
lymphocyte function including antibody production and increases
susceptibility to infections.
Lower selenium concentrations in humans have been linked with
diminished natural killer cell activity and increased mycobacterial disease.
Selenium deficiency was shown to permit mutations of coxsackievirus,
polio virus and murine influenza virus increasing virulence.
These latter observations suggest that poor selenium status could result in
the emergence of more pathogenic strains of virus, thereby increasing the
risks and burdens associated with viral infection.
Selenium supplementation (100 to 300 μg/day depending on the study) has
been shown to improve various aspects of immune function in humans,
including in the elderly. Selenium supplementation (50 or 100 μg/day) in
adults in the UK with low selenium status improved some aspects of their
immune response to a poliovirus vaccine.

possible antiviral activity by interfering with SARS-CoV-2/angiotensin-converting enzyme 2 association. As an antioxidant,
and anti-inflammatory and immunomodulatory compound, melatonin impairs the consequences of SARS-CoV-2 infection.
Melatonin is an effective chronobiotic agent that reverse circadian disruption and delirium in intensive care unit patients.
Melatonin may prevent neurological sequelae in COVID-19-infected patients like “brain fog” and cognitive decay. Melatonin

  • 2. Certain probiotic organisms appear to enhance innate immunity (particularly phagocytosis and natural killer cell activity), but they seem to have a less pronounced effect on acquired immunity. Studies show improved vaccination responses in individuals taking. Recent systematic reviews and meta-analyses confirm that probiotics or prebiotics (these are usually non-digestible oligosaccharides that act as fuels for some types of bacteria enhancing their growth; many probiotics are bifidogenic) enhance the antibody response to seasonal influenza vaccination in adults. The studies with probiotics have most often used lactobacilli or bifidobacteria.
  • 3. Upon virus attack in epithelial cells, probiotic bacteria have a crucial role in antiviral immunity via modulation of host immunological responses, including activation of NK cells, balancing Th1/Th2-mediated immunity, production of inflammatory cytokines, and specific antibodies Activation of immune response leads to the differentiation of CD8+ T-lymphocytes into cytotoxic T-lymphocytes, capable of destroying virus-infected cells. Next, CD4+ T-lymphocytes cells can differentiate into Th1, which activates phagocytosis through NK cells and macrophages, promoting pathogen killing. Further, CD4+ cells differentiate into Th2 cells, which induce B-cells proliferation, resulting in the production of antibodies that may play a crucial role in combating coronavirus proliferation. Thus, probiotic bacteria may catalyze useful immune responses and improve immune homeostasis in coronavirus- infections.
  • 4. Fig. 2. Schematic depiction of putative mechanisms by which probiotics may help manage coronavirus infection. (A) Probiotic bacteria can hinder the adsorption process via directly binding to the virus and inhibiting entry into epithelial cells. (B) Binding of probiotic bacteria to the epithelial surface can cause steric hindrance and block the virus's attachment to the host cell receptor. (C) Probiotic bacteria releases antimicrobial substances (such as bacteriocins, biosurfactants, lactic acid, hydrogen peroxide, nitric oxide, organic acids) and intestinal mucins from mucosal cells, which can effectively inhibit virus proliferation. (D) Virus neutralized by secretory antibodies like IgA. (E) Upon virus attack in epithelial cells, probiotics mediate their antiviral effects by eliciting immune responses by activating macrophages and dendritic cells. (F) Activation of immune response leads to differentiating CD8+ T lymphocytes into CTLs, capable of destroying virus-infected cells. (G) CD4+ T lymphocytes cells differentiate into Th1, which activates phagocytosis through NK cells and macrophages, promoting pathogen killing. (H) CD4+ cells differentiate into Th2 cells, which induce B-cells' proliferation that produces antibodies like IgA, IgG, and IgM. CTLs, cytotoxic T-lymphocytes; Th1, T-helper cells type 1.

  • 10. Oxidative stress is a condition that reflect an imbalance between biological defensive and aggressive system, mediated by excessive production of reactive oxygen species (ROS), e.g., O2− (superoxide radical), ⋅OH (hydroxyl radical), and H2O2 (hydrogen peroxide), in which there is an inability of the antioxidant mechanisms to neutralize them. This process results in toxic effects and alterations of the normal redox state, which is associated with cellular damage and lipid peroxidation
  • 11. Studies have shown that inflammation and oxidative stress are interconnected phenomena, which are involved in pathological conditions as cardiovascular, kidney, liver disease, and cancer. In this way, during inflammatory events occur exacerbated production of ROS in the damaged inflammatory tissue, which can stimulate and had a critical role in the signaling pathway for inflammatory mediators production, such as proinflammatory cytokines and chemokines, resulting in inflammatory cell migration.

  • 16. • History of Phytochemicals • Phytochemicals exist as long as plants exist but we only know about hundred years about their existence. Medicinal plants are traditionally used all over the world. It is likely that the knowledge of traditional medicine developed through trial and error over many centuries. • The Chinese have the oldest medicine system. More than 5000 years ago, the Chinese based their medicine on the influence of yin and yang, and on the five elements. The earliest records about herbal medicine dates back to 2800 BC when the Chinese emperor Shen Nong wrote the text The Great Native Herbal.
  • 17. One of the first written texts covering the use of ginseng as a medicinal herb was the Shen Nong Pharmacopoeia, written in China in 196 AD. In his Compendium of Materia Medica herbal of 1596, Li Shizhen described ginseng as a "superior tonic". However, the herb was not used as a "cure-all" medicine, but more specifically as a tonic for patients with chronic illnesses and those who were convalescing.
  • 18. Emperor Shen-Nung was the second of China's mythical emperors (3500-2600 BCE). Widely considered the father of Chinese medicine, he catalogued over 365 species of medicinal plants which he personally tasted. Through his treatise ‘Shen Nung Benchau Jing’, we relive Emperor Shen-Nung's contribution to urology with reference to his management of erectile dysfunction. Time-related sources in medical and historical literature were reviewed, including the ‘Shen Nung Benchau Jing’ (The medicine book of Emperor Shen-Nung), archives and manuscripts at the Wellcome History of Medicine Collection, the Royal Society of Medicine, London, The Hong Kong Museum of Medical Sciences, and The Museum of Medical History, Shanghai, China. Chinese traditional herbal medicine began approximately 5000 years ago. Agricultural clan leader, Emperor Shen-Nung, was said to have a ‘crystal-like belly’ to watch the reactions in his own stomach of the herbs he collected. Ginseng was among of Shen Nung's contributions to herbal medicine
  • 19. Hippocrates (460-377 BC) and Aristotle (384-322 BC) introduced the herbal medicine from India and Egypt to Europe.
  • 20. The Greek physician Dioscorides wrote the book De Materia Medica in the first century AD. https://en.wikipedia.org/wiki/De_materia_medica De materia medica (Latin name for the Greek work Περὶ ὕλης ἰατρικῆς, Peri hulēs iatrikēs, both meaning "On Medical Material") is a pharmacopoeia of medicinal plants and the medicines that can be obtained from them. The five-volume work was written between 50 and 70 CE by Pedanius Dioscorides, a Greek physician in the Roman army. It was widely read for more than 1,500 years until supplanted by revised herbals in the Renaissance, making it one of the longest-lasting of all natural history books. The work describes many drugs known to be effective, including aconite, aloes, colocynth, colchicum, henbane, opium and squill. In all, about 600 plants are covered, along with some animals and mineral substances, and around 1000 medicines made from them .
  • 21. De materia medica was circulated as illustrated manuscripts, copied by hand, in Greek, Latin and Arabic throughout the mediaeval period. From the sixteenth century on, Dioscorides' text was translated into Italian, German, Spanish, and French, and in 1655 into English. It formed the basis for herbals in these languages by men such as Leonhart Fuchs, Valerius Cordus, Lobelius, Rembert Dodoens, Carolus Clusius, John Gerard and William Turner. Gradually these herbals included more and more direct observations, supplementing and eventually supplanting the classical text. Several manuscripts and early printed versions of De materia medica survive, including the illustrated Vienna Dioscurides manuscript written in the original Greek in sixth-century Constantinople; it was used there by the Byzantines as a hospital text for just over a thousand years. Sir Arthur Hill saw a monk on Mount Athos still using a copy of Dioscorides to identify plants in 1934.

  • 38. best diet to support the immune system is one with a diverse and varied intake of vegetables, fruits, berries, nuts, seeds, grains and pulses along with some meats, eggs, dairy products and oily fish. This diet is consistent with those regarded as generally healthy and is consistent with current dietary guidelines. Such a diet would preclude too much processed and ‘junk’ food and excessive amounts of saturated fat and sugar.
  • 39. Nutrition, immunity and COVID-19 by Philip C Calder
  • 40. A vitamin Vit. A (retinol, retinal, retinoic acid, retinyl palmitate, beta-carotene)
  • 42. Vitamin A is important for normal differentiation of epithelial tissue and for immune cell maturation and function. Thus,vitamin A deficiency is associated with impaired barrier function, altered immune responses and increased susceptibility to a range of infections. Many aspects of innate immunity, in addition to barrier function, are modulated by vitamin A and its metabolites. Vitamin A controls neutrophil maturation and in vitamin A deficiency blood neutrophil numbers are increased, but they have impaired phagocytic function. Therefore, the ability of neutrophils to ingest and kill bacteria is impaired. Vitamin A also supports phagocytic activity and oxidative burst of macrophages, so promoting bacterial killing. Natural killer cell activity is diminished by vitamin A deficiency, which would impair antiviral defences. The impact of vitamin A on acquired immunity is less clear and may depend on the exact setting and the vitamin A metabolite involved. Vitamin A controls dendritic cell and CD4+ T lymphocyte maturation and its deficiency alters the balance between T helper 1 and T helper 2 lymphocytes.
  • 43. Studies in experimental model systems indicate that the vitamin A metabolite 9-cis retinoic acid enhances T helper 1 responses. Retinoic acid promotes movement (homing) of T lymphocytes to the gut-associated lymphoid tissue. Interestingly, some gut-associated immune cells are able to synthesise retinoic acid. Retinoic acid is required for CD8+ T lymphocyte survival and proliferation and for normal functioning of B lymphocytes including antibody generation. Thus, vitamin A deficiency can impair the response to vaccination In support of this, vitamin A-deficient Indonesian children provided with vitamin A showed a higher antibody response to tetanus vaccination than seen in vitamin A-deficient children. Vitamin A deficiency predisposes to respiratory infections, diarrhea and severe measles. Systematic reviews and meta-analyses of trials in children with vitamin A report reduced all-cause mortality, reduced incidence, morbidity and mortality from measles and from infant diarrhoea, and improved symptoms in acute pneumonia.
  • 48. B vitamins are involved in intestinal immune regulation, thus contributing to gut barrier function. Folic acid deficiency in animals causes thymus and spleen atrophy, and decreases circulating T lymphocyte numbers. Spleen lymphocyte proliferation is also reduced but the phagocytic and bactericidal capacity of neutrophils appears unchanged. In contrast, vitamin B12 deficiency decreases phagocytic and bacterial killing capacity of neutrophils, while vitamin B6 deficiency causes thymus and spleen atrophy, low blood T lymphocyte numbers and impaired lymphocyte proliferation and T lymphocyte-mediated immune responses.
  • 49. Vitamins B6 and B12 and folate all support the activity of natural killer cells and CD8+ cytotoxic T lymphocytes, effects which would be important in antiviral defence. Patients with vitamin B12 deficiency had low blood numbers of CD8+ T lymphocytes and low natural killer cell activity. In a study in healthy older humans, a vitamin B6-deficient diet for 21 days resulted in a decreased percentage and total number of circulating lymphocytes, and a decrease in T and B lymphocyte proliferation and IL-2 production.61 Repletion over 21 days using vitamin B6 at levels below those recommended did not return immune function to starting values, while repletion at the recommended intake (22.5 μg/kg body weight per day, which would be 1.575 mg/day in a 70 kg individual) did. Providing excess vitamin B6 (33.75 μg/kg body weight per day, which would be 2.362 mg/day in a 70 kg individual) for 4 days caused a further increase in lymphocyte proliferation and IL-2 production.

  • 56. Vitamin C is required for collagen biosynthesis and is vital for maintaining epithelial integrity. It also has roles in several aspects of immunity, including leucocyte migration to sites of infection, phagocytosis and bacterial killing, natural killer cell activity, T lymphocyte function (especially of CD8+ cytotoxic T lymphocytes) and antibody production. Jacob et al. showed that a vitamin C-deficient diet in healthy young adult humans decreased mononuclear cell vitamin C content by 50% and decreased the T lymphocyte-mediated immune responses to recall antigens.
  • 57. Vitamin C deficiency in animal models increases susceptibility to a variety of infections. People deficient in vitamin C are susceptible to severe respiratory infections such as pneumonia. A meta-analysis reported a significant reduction in the risk of pneumonia with vitamin C supplementation, particularly in individuals with low dietary intakes Vitamin C supplementation has also been shown to decrease the duration and severity of upper respiratory tract infections, such as the common cold, especially in people under enhanced physical stress.

  • 62. The active form of vitamin D (1,25-dihydroxyvitamin D3) is referred to here as vitamin D. Vitamin D receptors have been identified in most immune cells and some cells of the immune system can synthesise the active form of vitamin D from its precursor, suggesting that vitamin D is likely to have important immunoregulatory properties. Vitamin D enhances epithelial integrity and induces antimicrobial peptide (eg, cathelicidin) synthesis in epithelial cells and macrophages,directly enhancing host defence. However, the effects of vitamin D on the cellular components of immunity are rather complex. Vitamin D promotes differentiation of monocytes to macrophages and increases phagocytosis, superoxide production and bacterial killing by innate immune cells. It also promotes antigen processing by dendritic cells although antigen presentation may be impaired. Vitamin D is also reported to inhibit T-cell proliferation and production of cytokines by T helper 1lymphocytes and of antibodies by B lymphocytes, highlighting the paradoxical nature of its effects. Effects on T helper 2 responses are not clear and vitamin D seems to increase number of regulatory T lymphocytes. Vitamin D seems to have little impact on CD8+ T lymphocytes
  • 63. A systematic review and meta-analysis of the influence of vitamin D status on influenza vaccination (nine studies involving 2367 individuals) found lower seroprotection rates to influenza A virus subtype H3N2 and to influenza B virus in those who were vitamin D deficient. adults showed an independent inverse association between serum 25(OH)- vitamin D and recent upper respiratory tract infection. Other studies also report that individuals with low vitamin D status have a higher risk of viral respiratory tract infections. Supplementation of Japanese schoolchildren with vitamin D for 4 months during winter decreased the risk of influenza by about 40%.85 Meta- analyses have concluded that vitamin D supplementation can reduce the risk of respiratory tract infections

  • 67. In laboratory animals, vitamin E deficiency decreases lymphocyte proliferation, natural killer cell activity, specific antibody production following vaccination and phagocytosis by neutrophils. Vitamin E deficiency also increases susceptibility of animals to infectious pathogens. Vitamin E supplementation of the diet of laboratory animals enhances antibody production, lymphocyte proliferation, T helper 1-type cytokine production,natural killer cell activity and macrophage phagocytosis. Vitamin E promotes interaction between dendritic cells and CD4+ T lymphocytes. There is a positive association between plasma vitamin E and cell-mediated immune responses, and a negative association has been demonstrated between plasma vitamin E and the risk of infections in healthy adults over 60 years of age. There appears to be particular benefit of vitamin E supplementation for the elderly.
  • 68. Studies by Meydani et al94 95demonstrated that vitamin E supplementation at high doses (one study used 800 mg/day and the other95 used doses of 60, 200 and 800 mg/day) enhanced T helper 1 cell-mediatedimmunity (lymphocyte proliferation,IL-2 production) and improved vaccination responses, including to hepatitis B virus. Supplementation of older adults with vitamin E (200 mg/day) improved neutrophil chemotaxis and phagocytosis, natural killer cell activity and mitogen-induced lymphocyte proliferation. Secondary analysis of data from the Alpha-Tocopherol,Beta Carotene Cancer Prevention Study identified that daily vitamin E supplements for 5 to 8 years reduced the incidence of hospital treated, community-acquired pneumonia in smokers.

  • 79. Iron deficiency induces thymus atrophy, reducing output of naive T lymphocytes, and has multiple effects on immune function in humans. The effects are wide ranging and include impairment of respiratory burst and bacterial killing, natural killer cell activity, T lymphocyte proliferation and production of T helper 1 cytokines. T lymphocyte proliferation was lower by 50% to 60% in iron-deficient than in iron- replete housebound older Canadian women.These observations would suggest a clear case for iron deficiency increasing susceptibility to infection. There are different explanations for the detrimental effects of iron administration on infections. First, iron overload causes impairment of immune function.Second, excess iron favours damaging inflammation. Third, micro-organisms require iron and providing it may favour the growth of the pathogen. Perhaps for the latter reasons several host immune mechanisms have developed for withholding iron from a pathogen.

  • 83. Zinc inhibits the RNA polymerase required by RNA viruses, like coronaviruses, to replicate,suggesting that zinc may play a key role in host defence against RNA viruses. In vitro replication of influenza virus was inhibited by the zinc ionophore pyrrolidine dithiocarbamate, and there are indications that zinc might inhibit replication of SARS-CoVs in vitro. In addition, as discussed by Read et al, the zinc-binding metallothioneins seem to play an important role in antiviral defence. Zinc deficiency has a marked impact on bone marrow, decreasing the number immune precursor cells, with reduced output of naive B lymphocytes and causes thymic atrophy, reducing output of naive T lymphocytes. Therefore, zinc is important in maintaining T and B lymphocyte numbers. Zinc deficiency impairs many aspects of innate immunity,including phagocytosis, respiratory burst and natural killer cell activity.
  • 84. Zinc also supports the release of neutrophil extracellular traps that capture microbes.There are also marked effects of zinc deficiency on acquired immunity. Circulating CD4+ T lymphocyte numbers and function (eg, IL-2 and IFN-γ production) are decreased and there is a disturbance in favour of T helper 2 cells. Likewise, B lymphocyte numbers and antibody production are decreased in zinc deficiency. Zinc supports proliferation of CD8+ cytotoxic T lymphocytes, key cells in antiviral defence. Many of the in vitro immune effects of zinc are prevented by zinc chelation. Moderate or mild zinc deficiency or experimental zinc deficiency in humans result in decreased natural killer cell activity, T lymphocyte proliferation, IL- 2 production and cell-mediated immune responses which can all be corrected by zinc repletion.
  • 85. Zinc supplementation (30 mg/day) increased T lymphocyte proliferation in elderly care home residents in the USA, an effect mainly due to an increase in numbers of T lymphocytes. The wide ranging impact of zinc deficiency on immune components is an important contributor to the increased susceptibility to infections, especially lower respiratory tract infection and diarrhoea, seen in zinc deficiency.

Selenium deficiency in laboratory animals adversely affects several components of both innate and acquired immunity, including T and B lymphocyte function including antibody production and increases susceptibility to infections. Lower selenium concentrations in humans have been linked with diminished natural killer cell activity and increased mycobacterial disease. Selenium deficiency was shown to permit mutations of coxsackievirus, polio virus and murine influenza virus increasing virulence. These latter observations suggest that poor selenium status could result in the emergence of more pathogenic strains of virus, thereby increasing the risks and burdens associated with viral infection. Selenium supplementation (100 to 300 μg/day depending on the study) has been shown to improve various aspects of immune function in humans, including in the elderly. Selenium supplementation (50 or 100 μg/day) in adults in the UK with low selenium status improved some aspects of their immune response to a poliovirus vaccine.

Melatonin has possible antiviral activity by interfering with SARS-CoV-2/angiotensin-converting enzyme 2 association. As an antioxidant, and anti-inflammatory and immunomodulatory compound, melatonin impairs the consequences of SARS-CoV-2 infection. Melatonin is an effective chronobiotic agent that reverse circadian disruption and delirium in intensive care unit patients. Melatonin may prevent neurological sequelae in COVID-19-infected patients like “brain fog” and cognitive decay. Melatonin can be an adjuvant for augmenting the efficacy of anti-SARS-CoV-2 vaccines.
