Thirty dogs were exmained their gastric motility by means of strain gage meth od under the stimulation of various branches of vagus nerve by square pulses.Results were:1) Both vagotomized dogs showed remarkable increase of anti-peristaltic electrical discharges. In contrast there was no remarkable change on the normo peristaltic discharges.2) On the selectively vagotomized dogs both peristaltic electrical discharges descreased in height contrary to normals.3) After solid diet or hot milk, difference of patterns of normo peristaltic frequency between normal and selectively vagotomized dogs became remarkable. And its pattern in selective proximally vagotomized dogs was resemble to normals'.4) According to results of the stimulation with block or various sections of nerves it is considered that the antral branch of vagus nerve controls also motility of lower corpus. The propagation was very quick differing from anti-peristalsis. And it was considered to be cholinergic.5) By the stimulation of pyloric branch anti-peristalsis was scarcely occured. The pyloroplasty combined with selective vagotomy was not effective to decrease anti-peristaltic discharges after solid diet.","PeriodicalId":156233,"journal":{"name":"Japanese Journal of Smooth Muscle Research","volume":"10 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":"130158687","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 smooth muscle cells are enclosed with basement membrane, except where the specialized cell membrane interconnection (intrusion body) is present. This intrusion body is frequently observed in the areas where nerve elements are sparse. Fused membrane or quintuple layered system can not be observed.The unmyelinated nerve endings are distributed among the smooth muscle cells. In the wide extracellular spaces where the nervous elements are rather scant, naked axons are found with basement membrane. But when the nerve terminals are abundant, naked axons keep often intimate relationship with the muscle cells. They are either contact directly with the muscle cells without basement membrane or embedded deep in muscle cells.Occasionally, the smooth muscle cell membrane at the point of contact with the nerve ending shows the presence of endoplasmic reticulum and pinocytotic vesicles. The closest apposition of the axon and the muscle cell is about 80 A. At these contact points, the specialized structure such as secondary synaptic cleft seen in skeletal muscle is not clear. The synaptio vesicles in the axon are divided into two types following their average diameters of 500 A and 800 A. The smaller vesicles with 500 A diameter could further be classified into the granular and agranular types, and they are often found in the same axon. The functional differentiation of them is impossible at present.","PeriodicalId":156233,"journal":{"name":"Japanese Journal of Smooth Muscle Research","volume":"44 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":"124073245","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}

On the basis of the results obtained in the studies on the plexus-containing as well as plexus-free preparations, it is then concluded that acetylcholine released from intramural nervous elements is responsible for maintaining the rhythmic contractions. An evidence has also been presented that the pacemaker is the site, where the intramural nervous elements are distributed much more densely than any other places. Lastly, on the basis of the results obtained recently by Hukuhara and his co-workers the functions of intramural ganglion cells are summarized: The cells consist of excitatory and inhibitory neurones and function as centers of two kinds of intrinsic reflexes; the one is produced by stimulating the mucosa (mucosal intrinsic reflex), while the other by stimulating the muscle coat (muscular intrinsic reflex). The characteristic natures of the reflexes have been described, and evidences that these reflexes play an important role to regulate, on the one hand, the strength and direction of rhythmic contraction waves, and, on the other hand, the transport of contents through the digestive tract, have been presented. When the ganglion cells are completely destroyed, the intrinsic reflexes are completely absolished, and the tone of the muscle remarkably rises. The phenomena are shown to be a primary cause of congenital megacolon and the diseases belonging to the same category. The latter fact, moreover, suggests that in the normal condition the inhibitory neurones persistently discharge to cause a moderate relaxation of the muscle, whereas the excitatory ones are supposed to act only when the mucosa is stimulated.","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":"131948552","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}
