Gentamicin Induced Nephrotoxicity in Long Evans Rat - An Experimental Study
نویسنده
چکیده
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.

Objective(s): The aim of this study was to evaluate the effect of subacute administration of propylthiouracil (PTU) on gentamicin (GM)-induced nephrotoxicity in male rats. Materials and Methods: Male Wistar rats were divided into 4 experimental groups as follow: (1) Control group: isotonic saline (1 ml/kg, IP. for 18 d), (2) GM group: 100 mg/kg, IP for 8 d, (3) PTU group: PTU...
متن کاملL-methionine attenuates gentamicin nephrotoxicity in male Wistar rat: pathological and biochemical findings
The clinical uses of gentamicin have so far been restricted due to nephrotoxicity and ototoxicity. The exact mechanism of nephrotoxicity is still unknown; however, it appears that free radicals may be involved. Methionine has previously been shown to alleviate oxidative stress involved in ototoxicity due to its antioxidant properties. Therefore, the effect of methionine supplementation on the g...
