Diuretic effects of aqueous extract of Ficus exasperata Vahl. leaves in rat.

Ficus exasperata is widely used in african pharmacopoeia against hypertension and edema. The hypotensive effects of aqueous extract of F. exasperata leaves are reduced in the presence of atropine and methylene blue.

Myostimulating effect of sesamum radiatum aqueous leaf extract in isolated Guinea-pig Taenia caeci contractile activity.

This study was carried to examine the effects of the aqueous leaf extract of Sesamum radiatum, a laxative plant on the contractile activity of Taenia caeci, an intestinal smooth muscle. Strips of Taenia caeci were rapidly removed from guinea-pig and were suspended between two L-shaped stainless steel hooks in a 10 ml organ bath with Mac Ewen solution. The isometric contractile force of the Taenia caeci strips were recorded by using a strain gauge.
