Effect of Rotula aquatica Lour. on ethylene-glycol induced urolithiasis in rats.

The effect of the alcoholic extract of Rotula aquatica (Boraginaceae) against ethylene glycolinduced urolithiasis in albino rats is summarized in this study. Lithiasis was induced in rats by administrating 1% ethylene glycol in drinking water for 28 days and was manifested by high urinary calcium, phosphate, oxalate, protein, uric acid, creatinine and low urinary magnesium content. The alcoholic extract of Rotula aquatica was administered in 200 mg/kg body weight orally for 28 days along with 1% ethylene glycol. Urinary calcium, phosphate, oxalate, protein, uric acid, creatinine was reduced and urinary magnesium level was elevated. It also increased the urine volume, thereby reducing the tendency for crystallization. The histopathological studies confirmed the induction of lithiasis as microcrystal deposition was observed in section of kidney from animals treated with ethylene glycol. This was reduced, however, after treatment with the extract. These observations enable us to conclude that alcoholic extract of Rotula aquatica is effective against ethylene-glycol induced urolithiasis in albino rats.
