Studies on antidiarrhoeal activity of an extract of wine from Jacquez grapes in mice.

The present study was designed to verify the antidiarrhoeal effects of a lyophilized extract of wine from Jacquez grapes (Ord. Rhamnales; Fam. Vitaceae; Sp. Vitis aestivalis M.-cinerea E. x Vitis vinifera L.), studying its influence on castor oil-induced diarrhoea and enteropooling, and on gastrointestinal transit (measured by a charcoal marker) in mice. The pre-treatment of the animals with the JWE (Jacquez wine extract) produced a significant inhibition against castor oil induced-diarrhoea and intestinal fluid accumulation; furthermore the extract significantly decreased the propulsive movement of the charcoal meal. These findings suggest a potential beneficial use of the JWE in the treatment of diarrhoeal diseases.
