Abstract
In order to evaluate the protective effect of verapamil against
hexachlorobutadiene (HCBD) nephrotoxicity, 30 adult Wistar albino rats were
divided into five equal groups, A, B, C, D and E and were given intra-peritonially
corn oil (I ml/kg; control), HCBD (50 mg/kg), verapamil (50 μg/kg) with HCBD (50
mg/kg), verapamil (100 μg/kg) with HCBD (50 mg/kg) and verapamil (100 μg/kg)
with HCBD (100 mg/kg), respectively. Verapamil was given one hour before HCBD
treatment. All animals were killed after 24 hours. Serum concentrations of urea
and creatinine were higher (P<0.05) in HCBD-treated rats compared with the
controls, as well as verapamil treated groups. Histopathological examination of
kidneys showed substantial necrosis in straight portion of the proximal tubules
in HCBD treated rats. In verapamil-treated groups, kidneys appeared normal. It
was concluded that verapamil can protect kidneys against toxic effects of HCBD
in rats.
