Preventive effect of Cynodon dactylon against ethylene glycol-induced nephrolithiasis in male rats

Objective: This study was carried out to investigate the preventive effects of hydroalcoholic extract of Cynodon dactylon(C.dactylon) roots on calcium oxalate calculi in rat. Materials and Methods: 24 Wistar rats were randomly divided into 4 groups: group A received tap drinking water while, Groups B, C, and D received 1% ethylene glycol daily for 28 days. Rats in groups C and D received ethanolic extract of C.dactylon at doses equivalent to 3.2 mg/kg and 12.6 mg/kg of root powder, respectively in drinking water from day 0 to day 28. Urine and blood were collected on days 0 and 28 and analyzed for biochemical elements. After 28 days, the kidneys were removed and prepared for histological evaluation of calcium oxalate deposits (CaOx). Results: The number of CaOx deposits in 10 microscopic fields of kidney slices in group B was 24.5 ± 4.40 which was significantly higher than group A (
