Effects of gentamicin on Renal Parenchyma and Prevention by Vitamin E in Young Albino Rats.
Med Forum Jan ;3(2):18-22.

Objective: To determine the preventive role of Vitamin E on renal parenchyma after given of gentamicin in young albino rats. Study Design: Experimental study Place and Duration of 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. Methods and Material: 30 young 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 ┬Ám thick section cut by microtome and stained with H&E, PAS and silver methenamine. Renal histology was done under light microscope to see the proximal and distal tubular diameter and count. Results: 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. Conclusion: It may be concluded that gentamicin produces changes in kidney, which may be attributed to ischaemia resulting in tubular necrosis in young albino rats simultaneous administration of vitamin-E partially protect the morphological and histological changes induced by gentamicin.
