Amelioration of Carboplatin-Induced Changes in Rat Renal Cortical Tubulesby Alpha-Tocopherol

Objective: To determine the effects of carboplatin and alpha-tocopherol co-administration on gross kidney features and renal cortical tubules of carboplatin-treated rats. Study Design: Laboratory-based experimental study. Place and Duration of Study: Department of Anatomy, Army Medical College/National University of Medical Sciences Rawalpindi Pakistan, in collaboration with the National Institute of Health (NIH) and Pathology Lab Pak Emirates Rawalpindi Pakistan, from Jan to Dec, 2021. Methodology: Thirty adults "Sprague-Dawley rats" of both genders were used and were divided into three Groups. Group-A was the Control Group. Groups B and C were given injection carboplatin 2.5 mg/kg body weight intraperitoneally on the first day. Group-C was given vitamin E at a dose of 62.7 mg/kg body weight daily via oral gavage starting from the second day of the experiment till the end of 12 weeks. Rats were euthanized at the end, kidneys were dissected, and they were preserved in 10% formalin after gross inspection. Tissue processing and staining were performed. A microscopic study was done to observe proximal and distal tubule necrosis. Results: Thirty adult Sprague Dawley rats, of age 10-12 weeks, and weight 250.0±50.0 grams, were included, there was statistically significant difference in the animal weight difference (p=0.001), length of right kidneys (cm) (p=0.002), width of right kidney (cm) (p= 0.001) and weight of right kidney (gm) (p=0.012) kidneys and relative tissue body weight index (RTBWI) (p = 0.048) of Control Group-A and Experimental Group B and C. Conclusion: Alpha-tocopherol has an ameliorative effect on gross features of rat kidneys..........
