The purpose of the present study was to evaluate the nephroprotective and antioxidant properties of Triphala against bromobenzene-induced nephrotoxicity in female Wistar albino rats.

Drug-induced liver injury is the common adverse effect seen in patients receiving antituberculosis drugs (ATDs). There are several risk factors associated with the development of hepatotoxicity in such patients. Though there have been appreciable efforts taken by carrying out studies investigating the efficacy of several natural and synthetic compounds in minimising this effect, the only choice available for clinicians is withdrawal of drugs. This review would give a precise idea of ATD-induced hepatotoxicity, its underlying mechanisms and alternative therapies for the same.

OBJECTIVEThe purpose of the present study was to evaluate the nephroprotective and antioxidant properties of Triphala against bromobenzene-induced nephrotoxicity in female Wistar albino rats.

METHODSAnimals 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.

RESULTSBromobenzene 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.

CONCLUSIONTriphala 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.
