Gentamicin Induced Nephrotoxicity in Long Evans Rat - An Experimental Study
Context: Gentamicin is an antibiotic used in gram-negative infection. It is an nephrotoxic agent. Proximal tubular epithelial cells are selectively sensitive to gentamicin.
Objective: To observe the toxic effect of gentamicin on epithelial cells of proximal convoluted tubule in Long Evans rats.
Study design: An experimental study.
Plan and period of study: The study was carried out in the Department of Pharmacology of IPGMR Dhaka during the period of 1995 to 1996.
Materials and methods: Eighteen mature long Evans rats were divided into three groups A, B & C. The rats of group A were treated with vehicle and group B and C were treated with gentamicin 50gm and 100gm respectively. Blood urea and serum creatinine were measured and microscopic damaged cells were counted.
Result: There was significant increase in serum creatinin and blood urea in gentamicin treated groups. Microscopic examination of kidney showed necrosis of proximal tubular cells.
Conclusion: It can be concluded from this study that gentamicin has toxic effects on renal tubule.
Key words: Gentamicin.
