Unilateral vagotomy at the height of the neck resulted in the decrease in the acid secretory areas on both anterior and posterior walls of the stomach, which was later enhanced by bilateral vagotomy. Vagotomy also decreased an acidity of the gastric juice.2. Severance of vagi was attempted supradiaphragmatically and subdiaphragmatically as well. Section of the anterior branch showed an inclination in the reduction of an acid secretory area mostly of the anterior wall, and section of the posterior branch resulted in vice versa. This inclination of limited and partial reduction in the acid secretory area of the gastric mucosa was more predominant in the dogs where the vagus or vagi were severed subdiaphragmatically. Section of the vagus at these levels also reduced an acidity of the gastric juice.3. Out of the results described above, it was shown that the decrease in the acid secretory area well correlated with the vagally denervated area of the gastric mucosa traced anatomically from the site of vagotmy.4. In the reduction of an acid secretory area induced by vagotomy, it was of some interest to notice that the acid secretory area tended to localize to the corpus mucosa adjacent to the antral border. Histologically, this area well coincides with the richly distributed area of the parietal cells.","PeriodicalId":156233,"journal":{"name":"Japanese Journal of Smooth Muscle Research","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134263207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the use of electromyography, influence of vagotomy or splanchnectomy on this exciting condition of the gastric motility was studied.Vagotomy or splanchnectomy caused little changes in the gastric motility of the control dogs where transection of the stomach had not been performed precedently. When vagotomy or bilateral splanchnectomy was followed by the transection and end-to-end anastomosis of the stomach, development of frequent anti-peristalsis was observed distal to the anastomotic line. On the contrary, in a condition where frequent anti-peristalses are observed below the an astomotic line after transection and end-to-end anastomosis of the stomach, an addition of vagotomy or splanchnectomy was followed by no noticeable changes in the frequency of anti-peristalsis.Out of the results obtained in the present experiment, it is concluded. that the development of anti-peristaltic discharges after transection.and endto-end anastomosis is not related to the severence of gastric innervation, but, moreover, closely related to the excitation of the gastric wall per se caused by the transection of the stomach.","PeriodicalId":156233,"journal":{"name":"Japanese Journal of Smooth Muscle Research","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116583225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Uterine motility was recorded kymographically in conscious animals with the help of small balloon inserted through the fistulae. The results obtained are as follows: 1) A single intramuscular injection of vitamin D of 10,000 or 50,000 i.u. per kg body weight caused an increase in the uterine motility lasting 3 to 4 days, and then gradually was brought to its inhibition. 2) Daily intramuscular administration of ,5,000 or 10,000 i.u./kg for about 40 days caused an increase in the uterine motility for about first 2 weeks and later the motility was gradually suppressed. When, 50,000 i.u./kg was given daily, uterine activity was strongly inhibited from the beginning. 3) When vitamin D and estrogen were administered simultaneously, the increase in the frequency and amplitude of uterine contractions was observed. This seems that vitamin D has a synergetic action to estrogen. 4) The administration of progesterone with vitamin D caused an inhibition of the uterine motility in the beginning, but this inhibitory effect disappeared gradually with the prolongation of the period of administration. This suggests the antagonistic action of vitamin D against progesterone. 5) The senstivity of the uterine motility for oxytocin well correlated with the promoting action of vitamin D.","PeriodicalId":156233,"journal":{"name":"Japanese Journal of Smooth Muscle Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125979170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results obtained were as follows:(1) There were 1-4 compressions on the surface of the feces extruded in a short time after thecapture of animals. It may be presumed that the compressions are due to the tonic constriction rings produced on the large intestine at the moment of the defecation.(2) Among the former group the defecation interval of 12-24 hours ranked first (38.9%), and that of 24-36 hours came second (18.5%), that of 0-12 hours (17.1%) third, being followed by that of 36-48 hours (10 .9%); defecations (85.5%) for the most part thus occurred with intervals shorter than 48 hours . In the latter the intervals of defecations showed the tendency similar to that seen in the former .(3) When the animal defecated, it firstly set its hind legs slightly apart from each other, raising the coccyx a little, and the anus then swelled out to extrude the feces .When the extrusion of the feces was incomplete, the anus rhythmically repeated its swelling, the interval of which coincided with that of the large shortening contraction of the large intestine.","PeriodicalId":156233,"journal":{"name":"Japanese Journal of Smooth Muscle Research","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127227174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
