To evaluate the role of diclofenac sodium on renal parenchyma of young albino rats.

To study the effects of commonly used non steroidal anti-inflammatory drug diclofenac sodium on the kidneys of young albino rats after therapeutic dose. Early clinical and pharmacological studied of oral and parental forms of diclofenac sodium began shortly after the drug was discovered. However there is scanty information about the toxicities of normal dose of diclofenac in young albino rats. The present study is therefore designed to observe the gross and microscopic changes in kidney following administration of this drug in young albino rats. For this experimental study 16 albino rats were used; they were divided into two groups, each comprising of 8 animals. Group-1 received normal saline 10ml/kg body weight while group-2 received diclofenac sodium 2mg/kg body weight for two weeks. Micrometry was done on kidney tissue for proximal and distal tubular count, their diameter and the no of cells in these tubules. Highly significant changes were observed both in proximal and distal tubules of kidney. Even in therapeutic doses, Diclofenac Sodium causes damage to kidney tubules in young albino rats.

Adverse effects of diclofenac sodium on renal parenchyma of adult albino rats.

OBJECTIVE: To see the toxic effects of NSAID on kidney tissue of albino rats. METHODS: For this experimental study, 16 albino rats were taken. They were divided into two groups; A and B. The animals in group-A were given Normal Saline. Group-B received Diclofenac Sodium 2 mg/kg/day by feeding tube for 14 days. On day-15 all animals were sacrificed. Kidneys were removed, fixed, embedded in paraffin, section cut at 4 microm thick and stained with H&E, PAS, and silver methenamine. Renal histology was done under light microscope to see the renal tubular diameter, count and cellular detail. RESULTS: The result of present study revealed that diclofenac sodium in single daily dose of 2 mg/kg for a period of two weeks effectively produced destruction of proximal and distal convoluted tubules in adult albino rats showing the dilatation of tubule and flattening of tubular epithelium, disruption of brush border in proximal tubule and thickening of basement membrane around proximal and distal tubular epithelium. CONCLUSION: Diclofenac sodium induced nephrotoxicity causes the destruction of proximal and distal convoluted tubules showing the dilatation of tubule and flattening of its epithelium in albino rats.
