Antioxidant activity of Albizzia lebbeck (Linn.) Benth. in alloxan diabetic rats.

There is an increasing demand for natural anti-diabetic drugs, as continuous oral administration of insulin can culminate in many side effects and toxicity. In our endeavour to formulate some cost-effective herbal medicines for diabetes, we undertook this study to evaluate the antioxidant potential of aqueous extract of Albizzia lebbeck (ALL) in diabetic rats. The oxidative stress in alloxan-induced diabetic rats was determined by estimating the levels of thiobarbituric acid reactive substances (TBARS), conjugated dienes (CD) and reduced glutathione (GSH) in liver and kidneys.

Probing the anti-hyperlipidemic efficacy of the allspice (Pimenta officinalis Lindl.) in rats fed with high fat diet.

In this study, the anti-hyperlipidemic effect of aqueous extract of Pimenta officinalis (APO) was investigated in experimental rats fed with high fat diet (HFD). Hyperlipidemia in experimental rats was evidenced by a significant enhancement in the level of glycerol, triglycerides and phopholipids in serum, and also in liver and kidney tissues. HFD caused oxidative stress in these animals as shown by marked increment in the levels of thiobarbituric acid reactive substances (TBARS) and diene conjugates (CD), and a distinct diminution in reduced glutathione (GSH) content in liver and kidneys.

Effect of Coscinium fenestratum on hepatotoxicity in rats.

Anti-hepatotoxic activity of methanol extract of Coscinium fenestratum stem (MEC) was investigated against carbon tetrachloride-induced hepatopathy in rats. Hepatotoxic rats were treated with MEC for a period of 90 days (60mg/kg body weight, daily, orally by intubation). Anti-hepatotoxic effect was studied by assaying the activities of serum marker enzymes like aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma glutamyl transpeptidase, lactate dehydrogenase etc.

Antioxidant effect of Coscinium fenestratum in carbon tetrachloride treated rats.

Antioxidant effect of methanol extract of Coscinium fenestratum stem powder was examined using carbon tetrachloride-intoxicated rat liver as the experimental model. Hepatotoxic rats were treated with the methanol extract for 90 days (daily, orally at the dose of 60 mg/kg body weight). Lipid peroxidation in carbon tetrachloride-administered rats was evidenced by a marked elevation in the levels of thiobarbituric acid reactive substances and diene conjugates, and also a profound diminution in glutathione content in the liver.

Antioxidant activity ofcurculigo orchioides in carbon tetrachloride-induced hepatopathy in rats.

In this study antioxidant activity of methanol extract of rhizomes ofCurculigo orchioides (MEC) was investigated using carbon tetrachloride (CCl(4))-intoxicated rat liver as the experimental model. The hepatotoxic rats were administered MEC for 90 days (daily, orally at the dose of 70 mg per kg body weight). Lipid peroxidation (LPO) in CCl(4)-intoxicated rats was evidenced by a marked increment in the levels of thiobarbituric acid reactive substances (TBARS) and diene conjugates (CD), and also a distinct diminution in glutathione (GSH) content in the liver.
