The study investigated the effect of stem bark hydroalcoholic extract of cocoa (Theobroma cacao) on liver function of phenlyhydrazine (PHZ)-induced forty anaemic (treated) and normal albino rats divided into 8 groups of five rats each in the study. The activities of marker enzymes such as aspartate amino transferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALP), were assayed. In addition serum total protein, total bilirubin, albumin were determined. There was a significantly (p<0.05) decrease in AST of anaemic not treated rats compared to normal control rats with the exception of serum total protein, total bilirubin, direct bilirubin, albumin, ALT and ALP where no significant (p>0.005) change was recorded. In the group (anaemic rats) treated with bark extract of Theobroma cacao at the doses of 100, 200, and 500mg/kg, AST was significantly (p<0.05) reduced while there was significant (p>0.05) increase in serum total protein, total bilirubin, albumin, ALT and ALP. In the group (non anaemic rats) treated with graded doses of the extract 200mg, 500mg and 1000mg, there was a significant (p<0.05) of total bilirubin diect bilirubin, and AST while no significant (p>0.05) change was recorded. The study illustrate that the bark extract of Theobroma cacao possess antioxidant and membrane permeability properties. Dose of Theobroma cacao at 500mg does not have antianaemic potentials.

Carbon tetrachloride (CCl4) a pharmacological tool was used to induce liver damage in Wistar albino rats. Silymarin (100 mg/kg) and methanol extract of Lawsonia inermis Linn. family Lythraceae (known to possess hepatoprotective compounds) was used to reverse the liver damage caused due to CCl4 (induced toxicity). Hydroalcholic extract of stem bark and leaf of Lawsonia inermis Linn. was evaluated, for its restorative efficacy against CCl4 induced hepatotoxicity which was assessed in terms of biochemical and histopathological parameters. CCl4 produce the altitude levels of serum marker enzymes of alanine aminotransferase (ALT), asparate aminotransferase (AST), alanine phosphatase (ALP) and bilirubin in blood serum. Due to the toxicity of CCl4 cause turbine hepatic cell architecture, necrosis, inflammatory cell infiltration, congestion, and sinusoidal dilatation along with reduction of superoxide dismutase (SOD), catalase, Glutathione-S-transferase (GST) and glutathione peroxidase (GPx) appeared in liver tissue. SOD is the primary step in the defense mechanism involved in the antioxidant system against the oxidative stress. It diminishes by converting the superoxide radical in to peroxide and molecular oxygen. CAT or GPx reactions, also exert a similar effect thereby reducing the level of cellular damage. By oral administration of methanol extract of Lawsonia inermis Linn. plant extracts, i.e., stem bark extract (250 mg/kg b.wt.) and leaf extract (250 mg/kg b. wt.) the levels of these parameters was restored to near controlled (untreated) levels. Thus, the present study revealed that the extracts of stem bark and leaf of Lawsonia inermis Linn. offered protection against hepatotoxicity induced by CCl4.

Background: Whereas the efficacy of Entada abyssinica (fabaceae) extracts against various ailments has been scientifically validated, its safety has not been established. This study was undertaken to evaluate the toxicity effects of methanolic stem bark extract of E. abyssinica on biochemical, haematological and histological parameters of Wistar albino rats following repeated oral administration.Methods: Wistar albino rats of both sexes were randomized into groups and orally administered daily with determined doses (150, 300 and 600 mg/kg) of E. abyssinica methanolic extract using 1% tween 80 in distilled water as a control for 28 days. On the 29th day, all the animals were sacrificed and dissected to collect blood and selected organs. The serum and whole blood were assayed for biochemical and haematological parameters respectively while selected organs were examined for histopathological lesions. Numerical data was analyzed using graph pad prism and expressed as mean ± standard error of mean. The differences between the treatment and control groups were tested for statistical significance using one-way analysis of variance and/or Student’s t-test.Results: In repeated daily oral doses (150, 300 and 600 mg/kg), the methanolic stem bark extract of E. abyssinica did not cause significant alteration in majority of the biochemical and hematological indices. However, the extract significantly elevated the level of uric acid (all doses), aspartate aminotransferase (300 and 600 mg/kg), low density lipoproteins (150 mg/kg) and mean corpuscular heamoglobin concentration (all doses). On the other hand, the extracts reduced high density lipoproteins (150 and 300 mg/kg), mean corpuscular volume (all doses), haematocrit (150 and 600 mg/kg), mean platelet volume (150 and 600 mg/kg) and procalcitonin (150 mg/kg). In the vital organs, there were no significant lesions observed except at the highest dose (600 mg/kg) where there was mild evidence of lymphocyte infiltration in the liver and focal interstitial nephritis.Conclusion: The methanolic stem bark extract of E. abyssinica is relatively safe in Wistar albino rats when repetitively administered orally in small doses for a prolonged period of time. We recommend more chronic toxicity studies and clinical trials on herbal remedies containing this plant to ensure that its use is free of potential toxicity to humans.

AbstractObjectivesThe main objective of the present study is to evaluate the mitigative effect of hydroalcoholic extract of Momordica cymbalaria fruits against sodium fluoride (NaF) induced hepatotoxicity.MethodsIn this study, Wistar male albino rats were randomly divided into five groups of six rats each. Group I and II served as normal and toxic controls. Group III as plant control received extract at a dose of 400 mg/kg b. wt, p.o and Groups IV and V as treatment groups received extract at a dose 200 and 400 mg/kg b. wt, p.o for 30 days. All groups except Groups I and III received 100 ppm of NaF through drinking water. After completion of the study, blood collected for the estimation of liver blood serum biomarkers such as aspartate aminotransferases (AST), alanine aminotransferases (ALT), alkaline Phosphatase (ALP), direct and total bilirubin, total protein and albumin. The liver tissue homogenate was for estimation of lipid peroxidation, catalase, and reduced glutathione levels.ResultsThe results showed that NaF intoxication caused elevation of liver blood serum levels and lipid peroxidation; decreased levels of serum total protein, albumin and liver reduced glutathione, and catalase observed. The treatment groups showed decreased elevated serum biomarkers (ALT, AST, and ALP), liver lipid peroxidation and increased serum total protein and albumin, liver reduced glutathione and catalase levels in a dose-dependent manner. Histopathological studies also further strongly supported for mitigative effects of the plant.ConclusionsIn conclusion, our findings of the study indicated that M. cymbalaria fruits were a potential drug candidate in the treatment of NaF induced hepatotoxicity.

A toxicity study was made on Lepidium sativum L. seeds used in Saudi traditional medicine for the treatment of various ailments. Lepidium sativum L. seed fed to Wistar albino rats at 2% (w/w) was non-toxic, Ten percent (w/w) was toxic but not fatal and 50% (w/w) of the diet for 6 weeks was lethal and caused depression in growth rate and entero-hepato-nephrotoxicity. Organ lesions accompanied by anemia and leukopenia were correlated with alterations in serum AST and ALT activities and concentrations of total protein, cholesterol, urea, and other serum constituents.

Objective: The objective of this study was to determine if there were any harmful effects of monosodium glutamate (MSG) on the liver of Wistar albino rats chronically at three different doses, namely, low, mid, and high doses equivalent to human consumption doses in developing countries. Methods: The Wistar albino rats (n=24) were divided into four groups, namely control, Low dose MSG (180 mg/kg), Mid dose MSG (360 mg/kg), and High dose MSG (720 mg/kg). At the end of the experimental period (120 days), animal blood was collected retro-orbitally to analyze the liver enzymes such as aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), Total protein, Albumin, and Total Bilirubin in blood serum. Lipid profiles, namely, Triglycerides, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and Total cholesterol were subjected to analysis using blood serum. Results: Significant increase (p<0.05) in AST, ALT, ALP, and total bilirubin in serum of MSG induced low, mid, and high dose groups when compared to control group were recorded. There was a significant increase (p<0.05) in LDL, decrease in HDL, increase in total cholesterol and triglycerides of MSG-induced animal groups. Conclusion: The effects of MSG on serum liver enzymes and lipid profiles in this present animal study were not severely alarming even though the dosage was chronic which opens further discussion on the controversies revolving around MSG.
