Vancomycin (VCM), a glycopeptide antibiotic, is a drug widely used in severe infections. However, VCM induce notable nephrotoxic side effects. Naringenin (NAR) is a natural of flavonoid and are known as strongly antioxidant, nefroprotective, antiapoptotic, and anti-inflammatory. The purpose of this study was to determine the potential protective effects of NAR against VCM-induced nephrotoxicity by measuring apoptotic and oxidative stress markers and evaluating histopathological alterations in rats. For this purpose, we used male Wistar albino rats that divided into seven groups: (i) Control [saline, intraperitoneally (i.p.)], (ii) carboxymethyl cellulose (0.5% CMC, orally), (iii) VCM (400 mg/kg, i.p.), (iv) NAR100 (100 mg/kg, orally), (v) VCM + NAR25 (25 mg/kg, orally), (vi) VCM + NAR50 (5...

Silymarin (SLY), a flavonoid complex isolated from the seeds of Silybum marianum (Asteraceae), has antioxidant, anti-apoptotic, anti-inflammatory, and anti-lipid peroxidative effects. Vancomycin (VA), used for treating serious infections, has been associated with nephrotoxicity, which limits its use. Therefore, this study aimed to investigate the potential renoprotective effects of SLY on VA-induced nephrotoxicity using renal, apoptotic (caspase-3, caspase-8, and caspase-9 enzyme activities), and oxidative stress [nitric oxide (NO) and malondialdehyde (MDA)] markers; serum blood urea nitrogen (BUN) and creatinine levels; and histopathological examination. A total of 49 male Wistar albino rats were used (n = 7): control [saline, intraperitoneally (i.p.)], dimethyl sulfoxide (i.p.), VA [400 ...

We investigate role of atP sensitive potassium (KatP) channel in cytotoxic effect of cypermethrin on rataortic smooth muscle cells. cytotoxicity analysis was performed at 0, 0.1, 0.5, 10, 50, and 100 µMconcentrations of cypermethrin and the cell index (ci) was calculated. KatP currents were recorded usingpatch clamp technique for 50 and 100 µM concentrations and channel conductivity was determined byobtaining current-voltage characteristics. No cytotoxic effect was observed in the first 72 hours. at the96th hour, only at 100 µM concentration, the ci value decreased significantly compared to control groupand at 120 and 144th hours, it was observed that the ci value decreased significantly at all concentrations.currents and conductivities were significantly decreased at 50 and 100 µM concent...
