Ameliorative, Antioxidant and Immunomodulatory Potential of Vitamin D on Aminoglycoside Induced Acute Kidney Injury in Wistar Rats

摘要

Background: Acute kidney injury causes an abrupt decline in renal filtration and affects animals in a similar way to humans. Diagnosis can be made based on urinalysis, serum biochemistry and various biomarkers. The present study was conducted to evaluate the ameliorative, antioxidant and immunomodulatory potential of vitamin D in rats induced with acute kidney injury. Methods: In the present study, group A rats were taken as healthy control, group B rats were given gentamicin @ 100 mg/kg BW intraperitoneally for 8 days and were considered as disease control and group C rats were treated with Vitamin D @ 0.4 mu g/kg/day subcutaneously for 8 days along with intraperitoneal gentamicin injection. Reduced glutathione (GSH), lipid peroxide (LPO), catalase and superoxide dismutase (SOD) were estimated in erythrocytes on day 0, 4 and 8. Tumor necrosis factor alpha (TNF alpha) and interleukin 10 (IL 10) were also estimated along with urine and serum biochemistry on day 0, 4 and 8. Kidney tissue samples were collected on day 8 for histopathological examination. Result: The mean values of GSH, catalase and SOD were significantly (P<0.05) higher whereas the mean value of LPO was significantly (P<0.05) lower in group C compared to group B on day 4 and 8. On day 4 and 8, the mean value of TNF alpha was significantly (P<0.05) lower, while the mean value of IL-10 was significantly (P<0.05) higher in rats treated with vitamin D as compared to disease control. Histopathological examination along with urine and serum biochemistry revealed protective efficacy of vitamin D in acute kidney injury. Based on the findings of the present study, it is concluded that vitamin D is having ameliorative efficacy along with antioxidant and immunomodulatory potential in case of gentamicin induced acute kidney injury in Wistar rats. However, detailed studies are required to explore the therapeutic potential of vitamin D in clinical cases of kidney diseases.
