In view of suggested anti diabetic potential, effect of aqueous and cold extracts of Terminalia catappa Linn (Combretaceae) leaves, on fasting blood sugar levels and serum biochemical analysis in alloxan-induced diabetic rats was investigated. All the extracts of Terminalia catappa produced a significant anti diabetic activity at dose levels of 1/5 th of(More)
The effect of depletion of extracellular Ca2+ (Ca2+ext) on the loss of responsiveness of the guinea pig ileal longitudinal muscle (g.p.i.l.m.) and the rat vas deferens (r.v.d.) to K+ and cis-2-methyl-4-dimethylaminomethyl-1,3-dioxolane methiodide (CD), and K+ and noradrenaline (NA), has been examined and compared with the effects of a variety of local(More)
1. The contractile responses of rat vas deferens to noradrenaline and K+ are composed of phasic and tonic components both of which are dependent upon the concentration of extracellular Ca2+. 2. Lanthanum, La3+, and thulium ions, Tm3+, inhibited the noradrenaline and K+ induced responses, complete inhibition being obtained at approximately 10(-3) M-Ln3+. 3.(More)
BAY K 8644 (methyl-1,4-dihydro-2,6-dimethyl-3-nitro-4-(2-trifluoromethylphenyl) pyridine-5-carboxylate) and CGP 28 392 (ethyl-4(2-difluoromethoxyphenyl)-1,4,5,7-tetrahydro-2-methyl-5-++ +oxofuro- [3,4-b]pyridine-3-carboxylate) are closely related in structure to nifedipine and other 1,4-dihydropyridine Ca2+ channel antagonists. However, both BAY K 8644 and(More)
The effect of desipramine on the cumulative dose-response curves of noradrenaline and potassium (K+) was examined on the isolated rat vas deferens. An exposure of 10 min to 10(-7) M desipramine caused a leftward shift and an increase in the maximum response of cumulative dose-response curves of noradrenaline. Desipramine (10(-7) M), in contact with the(More)
