Objective:To investigate the effects of melatonin on renal inflammation,oxidative stress,apoptosis,as well as DNA and tissue damage in acrylamide-induced nephrotoxicity in rats.Methods:Fifty male rats were randomly divided into five groups.The control group received distilled water by gastric lavage for 11days and the acrylamide group was administered acrylamide(50 mg/kg,i.g.)for 11 days.The MEL10+ACR and MEL20+ACR groups received intraperitoneal melatonin 10 and 20 mg/kg,respectively,for 11 days,and acrylamide(50 mg/kg,i.g.)was administered 1h after melatonin injection.The MEL20 group was injected with melatonin(20 mg/kg)for 11 days.Kidney function tests were performed and biochemical and inflammatory parameters were determined.In addition,histopathological,immunohistochemical,and immunofluorescence examinations were carried out.Results:Melatonin significantly abated acrylamide-induced rise in serum urea and creatinine levels.Acrylamide caused oxidative stress,inflammation,apoptosis,as well as DNA and tissue damage in the kidneys.Melatonin treatment alleviated acrylamide-induced renal damage by exhibiting antioxidant,anti-inflammatory,and antiapoptotic effects.Moreover,melatonin significantly ameliorated acrylamide-caused histopathological changes in kidney tissue.Conclusions:Melatonin attenuates acrylamide-induced renal oxidative stress,inflammation,apoptosis,and DNA damage in rats.

Objective: To investigate the effects of probiotic bacteria on cisplatin(CP)-induced nephrotoxicity. Methods: In the present study, 50 Sprague-Dawley rats were used and randomly divided into five groups including control, CP, probiotic bacteria treatment groups with different doses(0.5 and 1 mL) and only probiotic bacteria group. After CP and probiotic administration on seven days, rats sacrificed under anesthesia on the eighth day. The serum urea, creatinine, and blood urea nitrogen levels were analyzed. In renal tissue, malondialdehyde levels, superoxide dismutase and glutathione activity, interleukin-8, interleukin-1β and tumor necrosis factor-alpha levels were determined and histopathological and immunohistochemical changes were also examined. Results: According to results, urea, creatinine and blood urea nitrogen levels as well as kidney weights increased in CP group. Also, CP induced inflammation, oxidative stress, DNA damage and apoptosis in kidney tissue and caused histopathological changes. Administration of the high dose of probiotic bacteria could prevent these changes and damages. Conclusions: This study reveals that probiotic bacteria has protective effects on CP-induced renal damage in rats.
