The relaxatory effect of Vitis vinifera leaf extract on rat uterus has been reported and it was postulated that, the extract relaxed through the blockade of voltage dependent calcium channels. The extract also, relaxed rat aorta through NO and was dependent on the functional endothelium. In the present study, the effect of Vitis vinifera hydroalcoholic leaf extract (VHLE) on rat vas deferens pr...

Several reports have shown the various effects of grape (Vitis vinifera) seed extract such as antioxidant, hypotensive, hypolipidemic and vasodilatory effects. The aim of present study was to investigate the effect of grape leaf hydroalcoholic extract on isolated rat tracheal contractions induced by KCl and acetylcholine.

We studied the effect of administering Cassia auriculata leaf extract to rats with experimentally induced liver damage. Hepatotoxicity was induced by administering 9.875 g/kg bodyweight ethanol for 30 days by intragastric intubation. C. auriculata leaf extract was administered at a dose of 250 mg/kg bodyweight daily in one group and 500 mg/kg bodyweight daily in another group of alcohol-treated...
