Transfusion medicine has evolved greatly over centuries from early attempts at blood transfusions in the 15th century that proved fatal, to modern safe practices. Some key developments include the first successful animal-animal transfusion in 1665, first human-human transfusion in 1818, discovery of blood groups in 1901 which aided compatibility testing, development of anticoagulants and storage techniques in the early 20th century, establishment of the first blood bank in 1936, and advances in screening and testing that have made transfusions much safer procedures over the past few decades.
blood and blood component have an important role in transfusion medicine. when blood contain all its part and no separation is done thats known as whole blood but when you centrifuge and separate it that is know as component. transfusion of whole blood is now adays absolute from transfusion service and blood components are transfuses now a days which is a good practice and beneficial for the patient

Anti ulcer drugs and their Advance pharmacology ||
Anti-ulcer drugs are medications used to prevent and treat ulcers in the stomach and upper part of the small intestine (duodenal ulcers). These ulcers are often caused by an imbalance between stomach acid and the mucosal lining, which protects the stomach lining.
||Scope: Overview of various classes of anti-ulcer drugs, their mechanisms of action, indications, side effects, and clinical considerations.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
2. People have always been fascinated by
blood.
Ancient Egyptians bathed in it, aristocrats
drank it, authors and playwrights used it
as themes, and modern humanity
transfuses it. The road to an efficient,
safe, and uncomplicated transfusion
technique has been rather difficult, but
great progress has been made.
3. • In 1492, blood was taken from three
young men and given to the stricken Pope
Innocent VII in the hope of curing him.
Unfortunately, all four died. Although the
outcome of this event was unsatisfactory,
it is the first time a blood transfusion was
recorded in history.
4. • The first research into blood
transfusion dates back to the
17th Century when British
physician William Harvey fully
described the circulation and
properties of blood in his De
Motu Cordis in 1628. The
first blood transfusions were
also attempted around this
time, although these were
unsuccessful and proved fatal
in humans.
5. • The first successful blood transfusion
recorded was performed by British
physician Richard Lower in 1665 when
he bled a dog almost to death and then
revived the animal by transfusing blood
from another dog via a tied artery.
6. • In 1667, Jean-Baptiste
Denis who was
physician to King
Louis XIV, performed
the transfusion of
blood from an animal
to a human. Denis
transfused the blood
from a sheep to a 15-
year old boy and later
to a labourer, both of
whom survived the
transfusions.
7. • After being banned for more than 150
years, the use of blood transfusion was
revived during the late 18th century.
• In 1818, the first successful man to man
blood transfusion was performed by
British obstetrician James Blundell. He
successfully transfused human blood to a
patient who had haemorrhaged during
childbirth.
8. • In 1901, Karl
Landsteiner, an
Austrian physician
discovered the first
human blood
groups, which helped
transfusion to
become a safer
practice.
His work early in the 20th century won a
Nobel Prize.
9.
10. • In 1913, an American surgeon called Reuben
Ottenberg suggested that patient and donor
blood should be grouped and cross matched
before a blood transfusion procedure. He
conclusively demonstrated the importance
of compatibility testing in his report of 128
cases of transfusion.
12. In 1914, Albert Hustin
reported the first
human transfusion
using citrated blood.
He added sodium
citrate and glucose to
the blood to preserve
it, and stop it from
clotting.
13. • In Russia, Dr Andre Bagdasarov introduced
blood preservation for 21 days at 4’C in
1932.
14. • Acid citrate dextrose (ACD), developed
in 1943 by Loutit and Mollison, allowed
for blood to be stored for up to 3 to 4
weeks.
• Citrate phosphate dextrose (CPD)
solution was subsequently adopted
after studies showed blood could be
stored for up to 28 days with better red
cell survival than ACD
15. • In 1936, Dr . Norman Bethune of Canada
established the first blood bank of the
world at Madrid in Spain during the
Spanish Civil War .
16. • In 1942, the first
Central blood bank of
India was established
at Calcutta to meet
the blood need of the
war. It was situated at
the site of the present
All India Institute of
Hygiene and Public
Health, Calcutta.
17. • In 1940, Edwin Cohn developed cold
ethanol fractionation, the process of
breaking down plasma into components
and products. Albumin, gamma globulin
and fibrinogen are isolated and become
available for clinical use.
18. • Another advance in transfusion was
development of the first cell separator in
1951 by Edwin Cohn; the cell separator
allowed blood to be separated into red
cells, white cells, platelets, and plasma.
19. • Until the 1950s, blood was collected
through steel needles and rubber tubing
into glass, rubber-stoppered bottles, which
were reused following washing and
sterilization.
• In 1952, Carl Walter, a researcher under
Harvey Cushing, and William Murphy
described a system in which the blood was
collected into a collapsible bag of polyvinyl
resin.
20. • In 1981, use of polyvinyl bags for collection,
storage and transfusion of blood was
legalised.
21. • In 1964, Plasmapheresis was introduced
as means of collecting plasma for
fractionation.
22. • In 1969, S. Murphy and F. Gardner demonstrated the
feasibility of storing platelets at room temperature,
revolutionizing platelet transfusion therapy.
23. • In 1964, Infection of jaundice through
blood transfusion was confirmed.
• In 1971, Hepatitis B surface antigen
(HbsAg) testing of donated blood began.
24. • In 1986, first AIDS patient due to blood
transfusion in Mumbai was reported.
25. • 1998 Supreme Court passed judgment on
blood transfusion and blood banking in India.
• Supreme Court banned buying blood
from commercial sellers in India.
• National Blood Transfusion Council and State
Blood Transfusion Councils were established
for improvement of Blood Banking services in
the country.
26. • Transfusion medicine has come a long way
due to multiple scientists, adventurous
physicians, courageous donors and patients,
especially in the last century. We owe much
to these pioneers.
