چکیده
cium was omitted from the medium, and markedly inhibited by the addition of cocaine. 3. Addition of reserpine or tyramine stimulated the release of catecholamine from the slices. The effect of reserpine was diminished in calcium free medium, but that of tyramine was not affected in calcium free medium. Cocaine had a weak inhibitory effect on the release of catecholamine caused by reserpine but no effect on the response to tyramine. 4. Calcium ion itself stimulated the released of catecholamine from the granules, but its effect was prevented by magnesium. From the above results it is suggested that calcium ion plays a cardinal role in the

A comparative study on the effects of new opioid compounds and morphine on the contractility of guinea pig ileum and mouse vas deferens
Considering the clinical significance of opioids, especially their application for the treatment of severe painful conditions including cancer pain and the requirement for the synthesis of more specific drugs with lower side effects, this study was conducted to perform a preliminary investigation on six newly developed opioid drugs. Our aim was to introduce drugs that act selectively on the opi...

Aloe vera is well-known for its pharmacological and nutritional properties. The aim of the present study was to determine the effect of A. vera gel extracts on the secretion and cell content of triglyceride (TG) and cholesterol (TC) in HepG2 cells and their short-term effects on the dietary hyperlipidemic guinea pig model. The effects of increasing concentrations of A. vera crude gel and its al...

متن کاملSpinal cord segments controlling the canine vas deferens and differentiation of the primate sympathetic pathways to the vas deferens.
This study was undertaken to explore the spinal cord segments controlling the canine and human vas deferens and differentiation of the mammalian sympathetic pathways to the vas deferens. Thoracolumbar white communicating rami (WCR) were electrically stimulated in the dogs. Stimulation of the 1st, 2nd, 3rd, and 4th lumbar WCR elicited an elevation of intraluminal pressure of the vas deferens in ...
متن کاملPrejunctional and postjunctional actions of heptanol and 18β-glycyrretinic acid in the rodent vas deferens
Heptanol and 18 beta-glycyrrhetinic acid (18 beta GA) block gap junctions, but have other actions on transmitter release that have not been characterised. This study investigates the prejunctional and postjunctional effects of these compounds in guinea pig and mouse vas deferens using intracellular electrophysiological recording and confocal Ca(2+) imaging of sympathetic nerve terminals. In mic...
