A study of effect of Nigella sativa oil in paracetamol induced hepatotoxicity in albino rats.

Background: Acetaminophen (paracetamol) toxicity is a common cause of drug induced hepatotoxicity in children and adults. Specific treatment of paracetamol induced hepatitis is available in the form of N acetylcysteine only. Nigella sativa (NS) is used for the treatment of various ailments. Many studies have shown that NS plant has hepatoprotective potential. Hence, this study study was carried out to explore the prophylactic and therapeutic effect of NS oil against hepatotoxicity induced by paracetamol. Methods: Hepatotoxicity was induced in rats by paracetamol and it was assessed using biochemical parameters such as serum (Sr.) alanine aminotransferase (ALT), Sr. aspartate aminotransferase (AST), Sr. bilurubin, Sr. alkaline phosphatase, and Sr. total protein. In addition, histopathological score was also assessed. The therapeutic and prophylactic effect of NS oil administration on paracetamol induced hepatotoxicity was investigated by using above mentioned biochemical and histopathological parameters. Results: Paracetamol administration leads to rise in serum liver enzymes ad fall in Sr. total protein levels. NS oil has heptoprotective effect. NS oil significantly reversed changes in serum levels of AST, ALT, alkaline phophatase, bilurubin, and total protein produced by paracetamol. Furthermore, histopathological changes produced by paracetamol were reversed. Conclusion: This study demonstrated that NS oil has hepatoprotective effect. NS oil administration can prevent or reverse the hepatotoxicity induced by paracetamol.

Effect of honey on hepatotoxicity induced by antitubercular drugs in albino rats.

Background: Drug-induced hepatotoxicity is a potentially serious adverse effect of antituberculosis treatment (ATT) regimens containing isoniazid, rifampicin and pyrazinamide. Many in vitro and in vivo studies revealed that honey possess antioxidant property and hepotoprotective property but there is no systematic work available to test the effect of honey on antitubercular drugs induced hepatotoxicity in rats. Hence present study was carried out to explore the prophylactic and therapeutic effect of honey with its antioxidant activity against hepatotoxicity induced by antitubercular drugs (Isoniazid, Rifampicin and Pyrazinamide) in albino rats. Methods: Hepatotoxicity in rats treated with antitubercular drugs (Isoniazid, Rifampicin and Pyrazinamide) was studied by assessing parameters such as Serum alanine aminotransferase (ALT), Serum aspartate aminotransferase (AST), Serum total protein, Serum Malondialdehyde (MDA) and Serum Superoxide dismutase activity (SOD). The effect of Honey as co-administration and administration after establishment of hepatotoxicity on above parameter was investigated. These biochemical observations were supplemented by Histopathological examination of liver. Results: Honey significantly reversed changes in serum levels of AST, ALT, MDA, SOD, total protein and also histopathological changes produced by Antitubercular drugs. It was found that honey significantly prevented as well as reversed Antitubercular drugs induced hepatotoxicity and antioxidant activity. Conclusions: The results of present study show that honey has significant prophylactic and therapeutic value against antitubercular drugs induced hepatotoxicity.

Hypolipidemic and antioxidant activities of pioglitazone in hyperlipidemic rats.

Background: Diabetes mellitus (DM) is an endocrine disorder characterized by abnormal carbohydrate, lipid and protein metabolism along with specific long-term complications which are associated with hyperlipidemia and oxidative stress. Hence, it is important to find hypoglycemic drug that improves lipid profile and reduces oxidative stress in diabetic patient. This study, therefore, was performed to investigate hypolipidemic and antioxidant potential of Pioglitazone (PIO) in hyperlipidemic rats. Methods: Hyperlipidemia was induced in normal rats by including 0.75 gm% cholesterol and 1.5 gm% bile salt in normal diet and these rats were used for the experiments. PIO hydrochloride was administered as 10 mg/kg and 30 mg/kg dose levels to the hyperlipidemic rats. Hypolipidemic activity was estimated by plasma lipid profile parameters while antioxidant potential was estimated by ascorbic acid, catalase activity, malondialdehyde and superoxide dismutase activity using standard methods. Statistical analysis was done by one way analysis of variance (ANOVA) followed by Dunnett’s test. Results: Treatment with 10 mg/kg and 30 mg/kg dose levels of PIO hydrochloride resulted in a significant decrease in serum TG and VLDL only in 30 mg/kg PIO treated group and significant increase in serum HDL in both groups, but no significant decrease in cholesterol and LDL in both PIO treated groups. PIO increased activities of catalase enzyme and concentration of malondialdehyde significantly in only 30 mg/kg PIO treated group. But there were no significant changes in the superoxide dismutase activity and ascorbic acid concentration in both PIO treated groups. Conclusions: The present study demonstrated that treatment with 10 mg/kg and 30 mg/kg dose levels of PIO hydrochloride improves the plasma lipid profile and also reduces oxidative stress in hyperlipidemic animals.

Lipid lowering and antioxidant potential of Asparagus racemosus in hyperlipidemic rats.

Background: Atherosclerosis is associated with hyperlipidemia which is a major risk factor for coronary artery disease. Therefore, treatment of hyperlipidemia is one of the major approaches to decrease the atherogenic process. Many studies revealed that Asparagus racemosus (AR) possesses hypolipidemic and antioxidant potential, but results were not consistent. Therefore, the present study was undertaken to investigate lipid lowering and antioxidant potential of AR root powder in hyperlipidemic rats. Methods: Hyperlipidemia was induced in normal rats by including 0.75 gm% cholesterol and 1.5 gm% bile salt in normal diet and these rats were used for the experiments. Dried root powder of Asparagus racemosus was administered as feed supplement at 5 gm% and 10 gm% dose levels to the hyperlipidemic rats. Plasma lipid profile, malondialdehyde, ascorbic acid, catalase and superoxide dismutase were estimated using standard methods. Statistical analysis was done by one way analysis of variance (ANOVA). Results: Feed supplementation with 5 gm% and 10 gm% Asparagus racemosus resulted in a significant decrease in plasma cholesterol, LDL and significant increase in HDL. But there were no significant decrease in triglycerides and VLDL. The feed supplementation increased activities of catalase, superoxide dismutase and ascorbic acid content increased significantly in both the experimental groups (5 and 10 gm% supplemented groups). But there was no significant change in the concentration of malondialdehyde in these groups. Conclusions: The present study demonstrated that addition of Asparagus racemosus root powder at 5 gm% and 10 gm% level as feed supplement reduces the plasma lipid levels and also acts as an antioxidant.
