METHODS： Animals were divided into five groups of six rats and treated as follows： Group I was a normal control and received no treatment, Group II received only bromobenzene （10 mmol/kg）, Groups III and IV received bromobenzene and Triphala （250 and 500 mg/kg, respectively）, Group V received Triphala alone （500 mg/kg）, and Group VI received bromobenzene and silymarin （100 mg/kg） Antioxidant status and serum kidney functional markers were analyzed. RESULTS： Bromobenzene treatment resulted in significant （P 〈 0.05） decreases in the activities of antioxidant enzymes such as catalase, superoxide dismutase, glutathione-S-transferase and glutathione peroxidase as well as total reduced glutathione. There was a significant （P 〈 0.05） increase in lipid peroxidation in kidney tissue homogenates. There were significant （P 〈 0.05） reductions in the levels of serum total protein and albumin as well as significant （P 〈 0.05） increases in serum creatinine, urea and uric acid. The oral administration of two different doses （250 and 500 mg/kg） of Triphala in bromobenzene-treated rats normalized the tested parameters. The histopathological examinations of kidney sections of the experimental rats support the biochemical observations. CONCLUSION： Triphala treatment alleviated the nephrotoxic effects of bromobenzene by increasing the activities of antioxidant enzymes and reducing the levels of lipid peroxidation and kidney functional markers.展开更多

It has been described in the Ayurveda text as a ＂Ftasayana＂ and to rejuvenat the debilitated organs. Ayurvedic physicians use Triphala for many ailments but most importantly to treat various gastrointestinal disorders. Scientific studies carried out in the past two decades have validated many of the ethnomedicinal claims and researches have shown Triphala to possess free radical scavenging, antioxidant, antiinflammatory, antipyretic, analgesic, antibacterial, antimutagenic, wound healing, anticariogenic, antistress, adaptogenic, hypoglycaemic, anticancer, chemoprotective, radioprotective and chemopreventive effects. Clinical studies have also shown that Triphala was found to have good laxative property, to improve appetite and reduce gastric hyperacidity. Studies have also shown that Triphala was effective in preventing dental caries and that this effect was equal to that of chlorhexidine. The current review addresses the validated pharmacological properties of Triphala and also emphasizes on aspects that need further investigation for its future clinic application.展开更多
