- verapamil produces a sustained contraction in isolated biventer-cervicis muscle of chickens between 2-8 days old. from cumulative dose-response curves, ed50 of was calculated for this effect of verapamil. when isolated chicken biventer-cervicis muscle was electrically stimulated, verapamil had no effect on twitch contractures but increased the base line tone of the muscle. glycerol treatment ...

The biological activity of a Habu (Trimeresurus flavoiridis) venom fraction with drug-metabolizing enzyme inhibitory action was studied. The venom fraction, which was isolated through Sephadex G-100 gel filtration and cation exchange chromatography on Amberlite CG50, caused an increase of vascular permeability and hemorrhage, but these actions were lost after heating at 70 degrees C for 5 min. ...

Objective. To estimate morphometric changes of the artificial bladder muscular wall, which was formatted terminal ileum, in experiment early and late postoperative periods.
 Materials methods. The investigation conducted chronic conditions on 22 mini-pigs, ageing from 16 to 19 mo. After performance cystectomy animals formatted, using ileum. In 3, 6 12 mo after formation were removed experi...

The effects of purified scorpion toxin (Tityustoxin or TsTX) were investigated on the isolated guinea-pig and rat ileum, rat spleen strip and hen rectal caecum. The contraction of the ileum was due only in part to the release of acetylcholine, whereas the contraction of the spleen strip and the relaxation of the rectal caecum were due to the release of catecholamines.

Inherent smooth muscle tone and acetylcholine-induced contractions of the isolated longitudinal muscle from guinea pig ileum are inhibited by 1.2 M ethanol. The inhibitions are antagonized by high concentrations of calcium ion in the external medium. Previous work has indicated that an acetylcholine-induced increase in potassium efflux from the ileal muscle is also inhibited by ethanol and reac...

A gastric duplication cyst is not a common anomaly of the alimentary tract. The most site tract ileum. We found non-communicating cyst, along with greater curvature stomach during feeding gastrostomy for isolated Oesophageal atresia. are reporting associated atresia and left side one additional floating rib. This third case report in English literature.

BACKGROUND AND AIMS The endothelin ETB receptor null rat (ETB(-/-)R) has an intestinal segment without ganglia, and this rat is characterised by intestinal obstruction similar to that observed in human Hirschsprung's disease. In the present study, we have examined the myogenic mechanism responsible for obstruction in the ETB(-/-)R. RESULTS The ETB(-/-)R had an enlarged belly and the average l...

Duplication of the gastrointestinal tract occur any part alimentary from tongue to anus. Male have slightly more predominance than females. Gastrointestinal duplication will a varied presentation. Ileum and oesophagus are most commonly involved. Colonic is rare can present with diagnostic difficulties. has presence well developed coat smooth muscle, intimately attached in mesentric region show ...
