Abstract
Aim: In this study we examined the effect of oral application of garlic form [garlic oil (GO)] on rats after renal ischemia-reperfusion (I/R) injury. Materials and methods: Forty male Wistar albino rats were divided into four groups: control, sham-operated, I/R, and I/R + GO. GO was diluted in water and administered by oral intubation three times each week for 6 weeks. All rats except sham-operated underwent 45 min of bilateral renal ischemia followed by 6 hr of reperfusion. Blood samples and kidney tissues were harvested from the rats, and then rats were killed. Serum urea, creatinine, and cystatin C levels were determined. Total antioxidant capacity (TAC), catalase (CAT), total oxidant status (TOS), oxidative stress index (OSI), myeloperoxidase (MPO), nitrite oxide (NO), and protein carbonyl (PC) levels in kidney tissue and blood were measured. In addition, kidney tissue histopathology was evaluated. Results: The serum urea, creatinine, and cystatin C levels were significantly higher in I/R group compared to I/R + GO group (p < 0.01). The serum and tissue antioxidant markers (TAC, CAT) were significantly lower in I/R group than I/R + GO group (p < 0.01). The serum oxidant markers (TOS, MPO, NO, and PC) were significantly higher in I/R group than I/R + GO group (p < 0.01). Also oral application of GO was effective in decreasing of tubular necrosis score. Conclusion: Based on the present data, we conclude that increased antioxidants and decreased oxidants modulated by oral application of GO attenuated the renal I/R injury.</.
