Hepatoprotective Activity of Chara Parpam in Ccl4 Induced RatsIOSR Journals
Siddha system of medicine provides most frequently and to the extent possible and promising therapy for the relief of signs and symptoms of liver disorder over the generations. Their high therapeutic quality and lack of toxicity are exceptional. The present experimental work was to evaluate the hepatoprotective properties of Siddha herbo-mineral formulation Chara Parpam by CCl4 induced hepatotoxicity in albino rats. Two doses of Chara Parpam (5 mg/kg and 10 mg/kg) were administered to rats. Protection of hepatocytes was evaluated by estimate the level of ALT, AST, ALP, serum bilirubin, total protein, serum albumin, sodium and potassium during the exposure of CCL4 on wistar albino rats and to evaluate the effect of different doses of Chara Parpam against hepatotoxicity induced by CCL4. Liver histology was performed 24 hours after the administration of trial drug Chara Parpam. The result indicated that the concentration of ALT, AST, and ALP, released by hepatocytes were significantly reduced in the presence of Chara Parpam. The cytoprotective effects of the Chara Parpam are dose-dependent. Through this work, we demonstrate for the first time the direct protection of liver cells by administration of Chara Parpam confirming its hepatoprotective properties.

Hepatoprotective Effect of Cestrum parqui L. aerial parts and Phytochemical ...Jing Zang
This study deals with the investigation of hepatoprotective effect of 70% methanolic extract from Cestrum parqui aerial parts and determination of the bioactive components of the plant. The hepatoprotective effect of Cestrum parqui methanol extract (100, 500, 1000 mg/kg) was analysed on carbon tetrachloride (CCl4)-induced acute liver injury. The administration of a single dose of 40% CCl4 (1ml/kg b.w.) causes an increase in the activities of serum alanine aminotransferase (ALT) and aspirate aminotransferase (AST) enzymes and so pretreated orally of a dose from Cestrum parqui methanol extract (100, 500, 1000 mg/kg) and silymarin (200 mg/kg) for three consecutive days prior to The administration of a single dose of CCl4 significantly prevented the increase in the activities of these enzymes. Histological analysis showed that Cestrum parqui methanol extract at doses of 500 and 1000 mg/kg and silymarin reduced the incidence of liver lesions including vacuole formation, neutrophil infiltration and necrosis of hepatocytes induced by CCl4. The extract cause a negative result on the antioxidative enzymes, superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GRd) and decreased malondialdehyde (MDA) level in liver, as compared to those in the CCl4-treated group and this suggests that the hepatoprotective activity of the extract is due to the antioxidant effect of the extract. Phytochemical analysis of the methanol extract from Cestrum parqui aerial parts showed that it contained different phytoconstituents, flavonoids, tannins, saponins, alkaloids, terpenes and carbohydrates.

BACKGROUND:
The current article aims to explore the protective potentials of α-tocopherol alone and the combination of allicin and vitamin B-complex against lead-acetate neurotoxicity on the cerebellar cortex.
MATERIALS AND METHODS:
Forty rats were divided into four groups (n=10). Group 1 was the control group. Group 2 received 10 mg/kg body weight (BW) of lead acetate. Group 3 was exposed to 10 mg/kg BW of lead acetate plus a combination of allicin (100 mg/kg BW) and vit. B-complex (40 mg/kg BW). Group 4 was administered lead acetate (10 mg/kg BW) and α-tocopherol (100 mg/kg BW). The animals received treatment for sixty days by oral gavage. All the groups were studied ultrastructurally and immunohistochemically with glial fibrillary acidic protein (GFAP).
RESULTS:
The affected groups revealed shrunken and degenerated Purkinje cells with irregular nuclei. The cytoplasm comprised several lysosomes, unhealthy mitochondria, and dilated Golgi saccules. The myelinated nerve fibers demonstrated breaking of the myelin sheaths, apparent vacuoles, and broad axonal spaces. Immunohistochemically, there was a tremendous surge in GFAP-positive astrocytes in the lead acetate-treated group. These histological and ultrastructural variations were ameliorated by the administration of α-tocopherol and the combination of allicin and vit. B complex. Moreover, an apparent decrease in the number of GFAP-positive astrocytes was obvious in the protected groups.
CONCLUSIONS:
Although both α-tocopherol and the combination of allicin and vit. B-complex can be used as possible adjuvant therapies to ameliorate nervous system ailments attributable to lead acetate, α-tocopherol showed more protective potential.

Objective: The study aims to evaluate the protective effects of coenzyme Q10 (CoQ10) and Cynara scolymus L (CS) on doxorubicin (dox)-induced toxicity.
Materials and Methods: Sixty male rats were divided into six groups. Group 1 as a control. Group 2 received dox (10 mg/kg) intraperitoneally. Group 3 received CoQ10 (200 mg/kg). Group 4 received CS (500 mg/kg). Group 5 received CoQ10 (200 mg/kg) and dox (10 mg/kg). Group 6 received CS (500 mg/kg) and dox (10 mg/kg). The rats were then evaluated biochemically and immunohistochemically.
Results: Dox produced a significant deterioration of hepatic and renal functional parameters. Moreover, an upsurge of oxidative stress and nitrosative stress markers. The expression of alpha-smooth muscle actin (α-SMA) was increased and proliferating cell nuclear antigen (PCNA) expression was decreased. Administration of CoQ10 and CS resulted in a significant improvement of hepatic and renal functional parameters, and an improvement of both α-SMA and PCNA.
Conclusion: It is concluded that pretreatment with CoQ10 and CS is associated with up-regulation of favorable protective enzymes and down-regulation of oxidative stress. That can be advised as a supplement to dox-treated patients.

The cost of administering modern anti diabetic drugs is usually beyond the reach of most people in
the low income group especially those in the developing world where the disease is on the increase. This has led
to the current shift to the use of preparations from various parts of plants because of the current increase in the
knowledge of their toxicity, side effects, active constituents and doses. This study was conducted to compare the
effects of the aqueous Carica papaya seed and leaf extracts on serum biochemistry of alloxan induced diabetic
rats especially glucose level. Male Wister rats weighing 150-200g were induced with single freshly prepared
alloxan monohydrate (150 mg/kg body weight).Diabetes was confirmed after seven days in alloxan-induced rats
showing fasting blood glucose levels ≥ 200mg/dl. The diabetic rats were randomly allocated into three
experimental groups which received Seed extract, leaf extract or normal saline depending on the group. The
extracts were administered orally for twenty-eight days after which the animals were sacrificed and blood
samples were collected for Biochemical analyses. The results showed that both extracts have significant
hypoglycaemic, hepatoprotective and nephroprotective effects although extract of the seed proved to be more
potent than that of the leaf

The aim of this analysis was to see whether the aqueous extract of the roots of Polygonum persicaria (PP) and its active principle, Tannic Acid (TA), had a hepatoprotective and antioxidant effect in rats provided Carbon tetrachloride (1.5 ml/kg, i.p). Twenty albino wistar rats were divided into five groups: control, CCl4-induced hepatotoxicity, hepatotoxicity with Polygonum persicaria and Tannic acid, and a normal group given 100 mg/kg silymarin. After 14 days, the rats were sacrificed. Toxicity testing was carried out on 12 rats. They were randomly allocated to one of three groups: control, Polygonum persicaria 200 mg/kg (B.wt), and Tannic acid 200 mg/kg (B.wt). The amounts of liver homogenate enzymes (glutathione peroxidase, glutathione-S-transferase, glucose-6-phosphatase dehydrogenase, and glutathione reductase enzymes) were greatly restored by extracts of PP and TA at the tested concentrations, supporting the biochemical results. Tannic acid, in contrast to Polygonum persicaria, tends to have a greater liver defensive role toward carbon tetrachloride-induced hepatotoxicity, as well as antioxidant properties and mild anticancer activity against cell viability at higher concentrations. The histological alterations in the liver indicated the injury. Polygonum persicaria & its active principle Tannic acid has strong antioxidant properties as well as hepatoprotective effects against CCl4-induced hepatotoxicity, as demonstrated by these observations.

Plants play an important role in the life of human, as the major source of food, as well as for the maintenance and improvement of health and for the elimination of the enemies since ages. Plants are the basic source of knowledge of modern medicine. The present study was conducted to evaluate the hepatoprotective activity of aqueos extract of aerial parts of Cinnamon zeylanicum are evaluated in alcohol induced hepatotoxicity in albino rats. Silymarin (100mg/kg) was given as reference standard. The aqueos extract of aerial parts of Cinnamon zeylanicum have shown very significant hepatoprotection against alcohol induced hepatotoxicity in albino rats in reducing SGOT, SGPT, Alkaline phosphatase (ALP) and GGT and levels of total bilirubin and total protein were investigated and showed an increase in alcohol induced rats when compared to control. The extracts of the test plant exhibited significant (p < 0.05) hepatoprotective activity against the alcohol induced liver models by improving liver function which was indicated by reduction in the levels of SGOT, SGPT, ALP, GGT, total bilirubin and total protein.
evaluation of hepatoprotective activity of bauhinia purpurea linn.pdfgynomark
Present study was carried out to investigate different extracts of Bauhinia purpurea (B.P) for its
hepatoprotective activity against CCl4 induced hepatotoxicity. Mature leaves of Bauhinia purpurea were
collected, authenticated and was subjected to extraction using different solvents like chloroform, alcohol and
water. Healthy wistar albino rats (150-200g) of male sex were used for the in-vivo investigations. Liver damage
was induced by administration of 30% CCl4 suspended in olive oil (1ml/kg body weight). Activities of liver
marker enzymes, glutamate oxaloacetate transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT),
acid phosphatase (AP), alkaline phosphatase (ALP),total albumin(TA), total bilirubin(TB), Total protein(TP),
direct bilirubin (DB) at a dose of aqueous extract of leaves (100 mg/kg) chloroform extract of leaf of B.P
(100mg/kg and 150 mg/kg) and ethanol extract of leaf of B.P (100mg/kg and 150 mg/kg) showed a significant
hepatoprotective effect in comparison with the standard (sylimarin). It is also confirmed by liver
histopathology of treated animals. The present study demonstrated the extracts of B.P have hepatoprotective
effect against CCl4 induced hepatotoxicity.
The present study revealed a significant decrease in
the serum enzyme levels which can be attributed to
hepatoprotection. BP extract was found to decrease
the levels of ALP, ACP significantly and there is a
dose dependent decrease in the elevated SGOT and
SGPT levels of the extracts when compared to CCl4
group.
CCl4 treated Liver showed perivenular necrosis,
steatosis with degree of steatosis being variable
from ballooning degeneration to necrosis. Central
lobular vacuoles, frequently dilated and congested
central veins were seen with dilatation of
surrounding sinusoids, which contradicted to the
observations of standard sylmarin, the aqueous,
chloroform and alcoholic extracts showed a clear
portal tract and central vein with normal lobular
architecture and decreased cell degeneration
indicating the hepatoprotective action of extracts of
B.purpurea. The histopathological studies further
confirmed the above results presented in fig 1-8.
Therefore, from the above study the extracts of
Bauhinia purpurea exhibited potent
hepatoprotective activity against CCl4 induced liver
toxicity which can be ascribed to its ability to
decrease the oxidative damage.

ABSTRACT
Background:The main objective of the study is to determine the anti-arthritic effect of whole plant ethanolic extract of Polygonum glabrum
belonging to the family Polygonaceae in Female wistar rats using the Freund’s Complete Adjuvant (FCA) model . Methods:The plants areal
parts were collected near Tirupathi hills, Chittoor district of Andhra Pradesh in India. The Phytoconstituents were identified through the
chemical tests. Ethanol (95%) was used to obtain the whole plant extraction through Soxhlet extractor. Female SD rats were used for antiarthritic
screening. Arthritis was induced using FCA, and the anti-arthritic effect of the ethanolic extract of P.glabrum was studied at doses
of 250 and500 mg/kg. The effects were compared with those of indomethacin (10 mg/kg). At the end of the study, theliver enzyme levels were
determined and a radiological examination was carried out. Results and Discussion:The preliminary phytochemical analysis of the ethanolic
extract of Polygonum glabrum showed the presence of alkaloids, tannins, flavonoids and saponins. P. glabrum at 250 and 500 mg/kg
significantly inhibited the FCA-induced arthritis in the rats. This was manifested by as a decrease in the paw volume. The arthritic control
animals exhibited a significant decrease in body weight compared with control animals without arthritis. P. glabrum treated animals showed
dose dependent reduction in decrease in body weight and arthritis.At the same time, P.glabrum significantly altered the biochemical and
haematological changes induced by FCA (P < 0.05). The anti-arthritic effect of P.glabrum was comparable with that of Indomethacin.
Conclusion:The whole plant extract of P.glabrum showed significant anti-arthritic activity against FCA-induced arthritis in female Wistar
rats.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

ABSTRACT
The antioxidant activity of Cee’Rich Vitamin C supplement was
investigated using carbon tetrachloride (CCl4, 2ml/kg s.c route)
intoxicated albino Wistar rat liver. The Cee’Rich Vitamin C
supplement was administered orally at a dose of 200 and 400mg/kg,
for 10 consecutive days. The doses were determined from the acute
oral toxicity study in albino mice. The CCl4 was administered to all the
groups except group I (normal control). Silymarin (100 mg/kg) was
used as a standard hepatoprotective drug. After 24h of the last
treatment, blood was withdrawn by retro orbital puncture and serum
SGPT, SGOT and LDH were determined. The SOD was calculated
from the liver homogenate. The results indicated that serum SGPT,
SGOT and LDH levels were significantly decreased where as SOD levels were significantly
increased in Cee’Rich Vitamin C treated rats. This study suggests that the presence of
flavonoids in the Cee’Rich Vitamin C supplement exhibit significant hepato protective effect
and could protect tissues from oxidative stress via a free radical- scavenging and antioxidant
mechanism.

oxidative stress related pathogenesis of various diseases. The human body possesses many
defense mechanisms against oxidative stress, including antioxidant enzymes and non-
enzymatic compounds. For proper maintenance of tissue structure and function, free radicals
and antioxidants should maintain equilibrium.
Exposure to environmental pollutants such as smoke, pesticides and ultra violet radiations
can cause,-the natural antioxidant mammalian mechanism to become insufficient, resulting in
excessive generation of free radicals. These free radicals in turn produce cellular distress and
damage to the structure and function of cell membranes leading to degenerative disorders like
Alzheimer's diseases, cataracts, liver injury, cardiovascular diseases, neoplasm disorders,
atherosclerosis, nephritis, diabetes, rheumatoid arthritis and inflammation.[1,2]
Antioxidants mediate their protective effects by directly reacting with free radicals,
quenching them and preventing damage to cellular components-consequently hindering
disease.[1,2]
Recently, interest has increased considerably in finding naturally occurring
antioxidants to replace synthetic antioxidants, which are restrictive due to their
carcinogenicity.[3]
The antioxidant phyto chemicals such as polyphenols, flavonoids and
related compounds found in medicinal plants have received increasing attention for their
potential role in the prevention of human diseases.[4]
As a result, ethno medicinal plants have
been investigated and reported to have antioxidant and radical scavenging potential.[5,6]

paraffin (1:2 v/v), 2 ml/kg bw (sc route), administered to induce liver toxicity in animals) on
the 2nd
, 3rd
, 5th
and 7th
day. Group V was treated with the standard reference drug Silymarin,
at a dose of 100 mg/kg bw (oral route) for 10 consecutive days, with CCl4 in liquid paraffin
(1:2 v/v), 2 ml/kg bw (sc route) on the 2nd
, 3rd
, 5th
and 7th
day.[10]
After 24 h of the last dose, blood was collected from retro-orbital plexus under ether
anesthesia. The blood samples were allowed to clot for 30 min, and the serum was separated
by centrifugation at 2500 g at 37°C. The supernatant liquid (serum) was separated, and
transferred in-to an Eppendorf tube and used for biochemical estimations.[10]
After blood
collection, the animals of all groups were sacrificed under light ether anesthesia, and
dissected.
Preparation of Liver Homogenate
The liver samples were rinsed in sterile ice cold saline and then homogenized in ice –cold
0.25 M sucrose, 1:10 w/v solution using a micro centrifuge. The homogenate was centrifuged
at 5000 rpm for 15 min, supernatant decanted and used for the estimation of antioxidants and
enzyme levels using standard kits.
Serum parameters
The following serum parameters were measured: Serum glutamic oxaloacetic transaminase
(SGOT), Serum glutamic pyruvic transaminase (SGPT) and Lactate dehydrogenase (LDH)
were assayed spectrophotometrically according to the standard procedures using
commercially available diagnostic kits.(Erba kit).[11]
Tissue parameter: Superoxide dismutase (SOD) was measured from tissue homogenates.

In-vivo antioxidant parameters
a. Estimation of SGOT
SGOT catalyzes the reversible transfer of an α - amino group between aspartate and
glutamate. It is an important enzyme in amino acid metabolism. SGOT is found in the liver,
heart, skeletal muscle, kidneys, brain and RBCs. Serum AST and ALT levels and their ratio
(AST/ALT) are commonly measured as clinical biomarkers for liver health. AST levels are
found to be increase in liver diseases, myocardial infarction, muscular dystrophy and
cholecystitis, whereas AST level are decrease in patients undergoing renal dialysis and those
with vitamin B6 deficiency.[12]
b) Estimation of SGPT
SGPT catalyzes the transfer of an amino group from L-alanine to α-ketoglutarate. The
products of this trans-amination are - pyruvate and L-glutamate. Normally, ALT is found
inside liver cells. But if the liver is inflamed or injured, ALT is released into the bloodstream.
Measuring blood levels of ALT provides useful information about the health of the liver
cells.[13]
ALT present in sample catalyzes the transfer of the amino group from L-alanine to α-
ketoglutarate forming pyruvate and L-glutamate. Pyruvate in the presence of NADH and
lactate dehydrogenase (LDH) is reduced to L-lactate. In this reaction NADH is oxidized to
NAD. The reaction is monitored by measuring the rate of decrease in absorbance at 340 nm
due to the oxidation of NADH to NAD. The reagent incorporates a reaction mechanism of
regenerating the NADH for the extended stability of the working reagent.
c) Determination of Serum LDH
LDH catalyzes the reduction of pyruvate with NADH to form NAD. The rate of oxidation of
NADH to NAD is measured as a decrease in absorbance which is proportional to the LDH
activity in the sample.
LDH is found in many body tissues, including the liver. Elevated levels of LDH may indicate
the liver damage. Serum LDH levels increase in myocardial infarction, pulmonary diseases,
hepatic disease, hemolytic anemia, renal diseases and muscular dystrophy.[14]

d. Super oxide dismutase (SOD)
SOD is an endogenously produced intracellular enzyme present in essentially every cell in
the body. Cellular SOD is actually represented by a group of metalloenzymes with various
prosthetic groups. The prevalent enzyme is cupro-zinc (CuZn) SOD, which is a stable
dimeric protein (32,000).[15]
SOD is considered to be fundamental in the process of
eliminating Reactive oxygen species ( ROI) by reducing (adding an electron to) superoxide
to form H2O2. Catalase and the selenium-dependent glutathione peroxidase are responsible
for reducing H2O2 to H2O.
Principle
The principle is based upon the method (NBT-NADH-PMS) of generation of oxygen by
NADH in the presence of 02 and the reduction of NBT (from yellow to blue) by 02 mediated
by PMS. SOD activity is measured as the inhibition of the rate of reduction of NBT by the
superoxide radical, observed at 560nm.
Procedure for SOD measurement
SOD activity was assayed by the method of Kono et. al.[16]. The assay system consisted of
EDTA 0.1mM, sodium carbonate 50 mM and 96 mM of nitro blue tetrazolium (NBT). In a
cuvette, 2 ml of above mixture, 0.05 ml hydroxylamine and 0.05 ml of PMS were mixed and
the auto-oxidation of hydroxylamine was observed by measuring the absorbance at 560 nm.
The results were calculated as units/mg protein, where one unit of enzyme is defined as the
amount of enzyme inhibiting the rate of reaction by 100%.[16]

Acute oral toxicity study: Acute toxicity studies revealed the non-toxic nature of the
Cee’Rich Vitamin C supplement up to a dose level of 2000 mg/kg body weight in mice.
There was no lethality or toxic reaction found at any of the doses selected during the study.
Therefore as per the CPCSEA guideline 420 it was thought that 2000 mg/kg was the LD50
cut off dose. Therefore 1/10th
and 1/5th
dose (200 mg/kg and 400 mg/kg) were selected for all
further in vivo antioxidant studies.

DISCUSSION
Antioxidants work against molecules that form free radicals, destroying them before they can
begin the domino effect that leads to oxidative damage. For example, certain enzymes in the
body, such as superoxide dismutase, work with other chemical to transfer free radical into
harmless molecules. Vitamin C is an antioxidant that may prevent cataracts and cancers of
11. www.wjpps.com Vol 5, Issue 2, 2016. 1175

the stomach; throat, mouth, and pancreas. It may also prevent the oxidation of LDL
cholesterol, lowering the risk of heart disease and liver disease. In the present study,
Cee’Rich Vitamin C was evaluated for antioxidant activity using hepatotoxicity induced by
CCl4 in rat model. Carbon tetra chloride has been extensively studied as a liver toxicant, and
its metabolites such as trichloromethyl radical and trichloromethyl peroxy radical are
reported to be involved in the pathogenesis of the liver. The results of the present study
indicate that Cee’Rich Vitamin C is non toxic upto a dose of 2g/kg body wt. with no
behavioral changes or death. Furthermore, this study found that the Cee’Rich Vitamin C
supplement, in doses of 200 and 400 mg/kg, p.o., significantly elevated SOD levels and
significantly decreased serum SGOT, SGPT and LDH levels when compared to the toxic
control group.
CONCLUSION
From the results of the present study, it is concluded that Cee’Rich–Herbal Vitamin C
supplement, formulated by M/s Suguna Foods Pvt Ltd, Herbal Division, Suguna Lifeherbs
Coimbatore, TN, possesses superior antioxidant properties that may serve to protect users
against diseases associated with oxidative stress.
