Malpighian tubules of Rhodnius prolixus can detect a blood borne agent during the diuresis. It has been suggested that the agent is ADH but this is in dispute. In the present investigation, vasopressin (1-300 mu i.u. cm-3) was found to have no effect on Malpighian tubule secretion when added to plasma, Rhodnius Ringer and Rhodnius Ringer + 5-HT. In addition, it was shown that incubation with sodium thioglycollate of plasma samples obtained from anaesthetized dogs, before and during stimulation of atrial receptors by distension of a balloon in the lumen of the left atrium, did not abolish the differences between test and control plasma samples detected by the Malpighian tubules. It is concluded that differences in plasma detected by the Malpighian tubules and related to the diuresis which results from left atrial stimulation are not attributable to changes in concentration of ADH.</p>","PeriodicalId":77774,"journal":{"name":"Quarterly journal of experimental physiology (Cambridge, England)","volume":"66 3","pages":"333-8"},"PeriodicalIF":0.0,"publicationDate":"1981-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1113/expphysiol.1981.sp002563","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17962664","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}

In these fibres, it is shown that first, there is a continuous relation between the maximum frequency of transmission of impulses and vagal temperatures ranging between 37 degrees C and the temperature at complete blockade (no conduction at 0.5 impulses . s-1) for these fibres; second, there is a direct relationship between the maximum frequency of transmission of impulses and the conduction velocity. It is concluded that the maximum frequency of transmission of impulses in vagal fibres attached to atrial receptors in the dogs is related to temperature and conduction velocity. This relationship between maximum frequency of transmission and temperatures provides a quantitative explanation for the previously observed effects of cooling the vagi on the responses to stimulation of atrial receptors which were used to show that the reflex increases in heart rate and reflex reduction in activity in renal nerves involved only atrial receptors attached to myelinated vagal fibres.</p>","PeriodicalId":77774,"journal":{"name":"Quarterly journal of experimental physiology (Cambridge, England)","volume":"66 3","pages":"321-32"},"PeriodicalIF":0.0,"publicationDate":"1981-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1113/expphysiol.1981.sp002562","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17962663","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}
