  This study is conducted to investigate the possible hepatoprotective action of Moringa oleifera Lam. (MO), a high value medicinal plant against a single high dose of APAP induced hepatotoxicity. Male Sprague Dawley rats were dosed with APAP (3000 mg kg-1 body weight; p.o.) to induce hepatocellular damage. In rats that were pretreated with MO (200 and 800 mg kg-1; p.o.) for 14 days prior to APAP treatment, there was a reduction of liver enzymes (ALT, AST and ALP) and also the restoration of glutathione level. The biochemical results showed parallel finding with the histopathological analysis in which liver sections obtained from rats pretreated with MO, the damage was blocked. Intriguingly, MO alone has significantly elevated the level glutathione compared to the control group. The findings has suggested that Moringa oleifera Lam. is a promising product in protecting the liver against APAP induced liver injury via the restoration and elevation of glutathione level in the liver.

  The global prevalence of overweight and obesity has reached epidemic proportions. Hyperlipemia couple with increased oxidative stress generates various degenerative diseases such as hypertension and cardiovascular problems. In the present study, a hypolipemic and weight reducing effects of crude Tamarindus indica L. pulp extract were examined in adult Sprague-Dawley rats fed a high-fat diet. Animals were fed on either normal chow or high-fat diet for 10 weeks for obesity induction and subsequently received either placebo or T. indica L. extract at 5, 25, 50 or 300 mg kg-1 chitosan via oral gavage for another 10 weeks. Treatment of obese rats with the T. indica pulp extract led to a decrease in the levels of plasma total cholesterol (TCHOL), low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG) and increase high-density lipoprotein cholesterol (HDL-C) level with concomitant reduction of body weight. The extract improved the efficiency of the antioxidant defense system, as indicated by increased superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities and subsequently resulted in significantly lower lipid peroxidation indices; malondialdehyde (MDA) level. Together these results indicate the potential use of T. indica extracts as hypolipemic and antioxidative agent apart from its ability to reduce body weight in obese-induced rats.

  This study was designed to determine whether zerumbone, an essential bioactive compound isolated from Zingiber zerumbet Smith protects against early ethanol induced liver injury in rats. Male Sprague-Dawley rats were administered with 0.05% (v/v) to 0.5% (v/v) of zerumbone for 14 days. Following the final dosage of zerumbone, the animals were administered with 50% (v/v) ethanol for 14 days. We have observed that pre-treatment of zerumbone had suppressed fatty liver formation following ethanol 50% (v/v) administration. Meanwhile, rats that were treated with ethanol only, found to show significant level of focal vacuolated fatty liver with focal necrosis in the mid zonal region. Therefore, fatty liver development was found to be extensively reduced in animals that were pretreated with zerumbone.

  This study is conducted to investigate the possible effect of zerumbone towards hepatoprotective activity against paracetamol intoxication. Male Sprague-Dawley rats were randomly divided into six groups consisted of 3-5 animals. Group I was administered with 0.2% zerumbone for 14 days prior to 3 g kg-1 paracetamol administration. Group II was given paracetamol only and group III was given 200 mg kg-1 of silymarin and paracetamol. Group IV was administered with zerumbone only and finally group V was treated with corn oil and 40% sucrose buffer as vehicle treated group. Animals were sacrificed at 4 and 24 h post treatment following diethyl ether. There was no significant changes in liver enzyme activities as well as histological observations at 4 h after paracetamol administration. Meanwhile, 24 h after paracetamol administration, the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were found to be reduced in rats that were pretreated with zerumbone compared to group that was treated with paracetamol only. Correspondingly, there was no hepatocellular necrosis observed in rats that were pretreated with zerumbone. The results obtained may have suggested that zerumbone exert hepatoprotective activities against paracetamol induced hepatotoxicity.
