Anti-urolithiatic Activity of Daidzin in Ethylene Glycol-Induced Urolithiasis in Rats.

Urolithiasis is a common urological disorder, which causes considerable morbidity in both genders at all age groups worldwide. Though treatment options such as diuretics and non-invasive techniques to disintegrate the deposits are available, but often they are found less effective in the clinics. In this work, we planned to investigate the ameliorative effects of daidzin against the ethylene glycol (EG)-induced urolithiasis in rats. The male albino rats were distributed into four groups (n = 6) as control (group I), urolithiasis induced by the administration of 0.75% EG (group II), urolithiasis induced rats treated with 50 mg/kg of daidzin (group III), and urolithiasis rats treated with standard drug 750 mg/kg of cystone (group IV). The urine volume, pH, and total protein in the urine were assessed. The activities of marker enzymes in both plasma and kidney tissues were analyzed using assay kits. The levels of kidney function markers such as calcium, oxalate, urea, creatinine, uric acid, magnesium, BUN, and phosphorous were estimated using assay kits. The status of antioxidants and inflammatory cytokines were also examined using kits. The renal tissues were examined by histopathological analysis. Our results revealed that the daidzin treatment effectively decreased the urine pH and protein level and increased the urine volume in the urolithiasis rats. Daidzin decreased the calcium, oxalate, uric acid, and urea, creatinine, and BUN levels and also improved the magnesium and phosphorus in the urolithiasis rats. The activities of AST, ALT, ALP, GGT, and LDH were effectively reduced by the daidzin in both serum and renal tissue. Daidzin also reduced the inflammatory marker and increased the antioxidant levels. Histopathology results also proved the therapeutic effects of daidzin. Together, our results displayed that daidzin is effective in the amelioration of EG-induced urolithiasis in rats.
