The effect of aqueous extract of orthosiphon thymiflorus on isolated skeletal muscles.

Effects of an aqueous extract of orthosiphon thymiflorus on acetyl choline induces contraction on isolated frog rectus abdominis muscle were studies. The aqueous extract of orthosiphon thymiflorus produced significant inhibitory effect on the dose response curve of acetyl choline. It is concluded that the aqueous extract of orthosiphon thymiflorus  may exert an inhibitory effect on the skeletal muscle contraction and may be due to inhibition of the effect of acetylcholine at the receptor site.

Anti - inflammatory activity of volatile oil of psidium guajava.

Volatile oil of Psidium guajava leaves obtained by steam distillation was given orally to study its effects on the exudation and proliferative phases of the inflammatory reaction, using technique of carragenin induced paw edema and cotton pellets in male albino rats. The anti inflammatory activity as compared with ketorolac tromethamine. In carragenin induced edemas,.

Anti-ulcer activity of the alkali preparation of the root and fresh leaf juice of moringa oleifera lam.

The alkali preparation of the root and fresh leaf juice of Moringa oleifera possessed significant dose -depen-dent anti-ulcer activity in experimentally induced acute gastric ulcers with aspirin, the anti-ulcer effect of the alkali preparation of the root seems to be more pronounced than that of the fresh leaf juice. Te anti-ulcer activity of the alkali preparation of the root could be due to its content of alkaloids or its anticholinergic and antihistaminic activities, or a combination of these factors.

Effect of L-dopa and L- methionine supplementation on bioproduction of ementine in callus cultures of cephaelis ipecacuanha.

Callus cultures were induced from leaf segments of Cephaelis ipecacuanha on modified gamborg medium containing 2,4 - dichlorophenoxy acetic acid (2mg/1) Indole acetic acid (1mg/1), kinetin (1mg/1) and sucrose (20g/1). The biogenetic profile for alkaloids was established. The established callus cultures were transferred to modified gamborg medium supplemented with L- DOPA (40 mg/1) and L methionine (3mg/1).
