Protective effect of vitamin E [a tocopherol acetate] on gentamicin-induced nephrotoxicity in adult albino rats

ABSTRACT

To determine the preventive role of Vitamin E on renal parenchyma after given of gentamicin in adult albino rats. Experimental study. This study was carried out in the Department of Anatomy Baqai Medical University and Muhammad Medical College, Mirpurkhas from June 2011 to November 2011. For this study, 30 adult albino rats were taken. They were divided into three groups ; A, B and C. The animals in group-A given normal saline 10 ml/kg/day intraperitoneal for 2 weeks. Group-B received gentamicin 100 mg/kg/day intraperitoneal for 2 weeks and group-C receives gentamicin 100mg/kg/day intraperitoneal with vitamin-E 2 mg/kg/day orally for 2 weeks. On day 15 all animals were sacrificed with deep ether anesthesia. Their kidneys were removed, fixed in 10% formalin. Representative blocks were taken and embedded in liquid paraffin. For routine histological examination 5 micro m thick section cut by microtome and stained with H and E, PAS and silver methenamine. Renal histology was done under light microscope to see the proximal and distal tubular diameter and count. No significant [P>0.05] changes were observed in the histopathology of kidney tissues of the groups A and C rats. The group B significantly [P<0.001] affected the histopathology of kidney. It may be concluded that gentamicin produces changes in kidney, which may be attributed to ischaemia resulting in tubular necrosis in adult albino rats simultaneous administration of vitamin-E partially protect the morphological and histological changes induced by gentamicin
