Evaluation of COX-2 Inhibitor Injurious Effects on Proximal Convoluted Tubular Diameter of Kidney with Favorable Impact of Lycopene in Albino Rats on the Basis of Microscopic Features

Objective: To analyze the harmful effect of COX-2 inhibitor on proximal convoluted tubular diameter of kidney, amendment by lycopene.

Research Design: Experimental Research.

Abode of Research: Animal House, JPMC, Karachi.

Materials and Methods: 90-120 days old, forty healthy adult male Albino rats of 200-220gm weight were taken for this study and distributed into 4 cliques, set 1was chosen as control, in Set 2 Celecoxib was given 0.05g/1000g by gavage, in set 3 Celecoxib was given0.05g/1000g by gavage with lycopene 0.05g/1000g by gavage and set4 lycopene was given0.05g/1000g by gavage for 30 days. At accomplishment of study, animals were sacrifice and tissues were preserved for staining.

Results: Inset 2 proximal convoluted tubular diameter became distended due to apoptosis of lining epithelial cells. They turn into low cuboidal from simple cuboidal cells along with ill-defined brush border at the luminal surface due to scarce microvilli and had disrupted basement membrane, however renal structure were amended in set3 which were given celecoxib with lycopene.

Conclusion: This study reveals that lycopene amended the apoptotic changes of set2.
