An electrotonic blockade and a local summation could be excluded as the cause of the escape within the physiological range. The maximum of the initial reaction was found at a stimulation strength between 12 and 16 V (10 Hz, 1 msec). The maximum of the escape reaction occurred at 5 V. Both vascular reactions were strongly dependent on the local concentration of noradrenaline (i.a. infusion); however, they reached their maximum at different concentrations. The escape reaction is apparently a persisting adjustment to a steady state. Despite a formal similarity, no correlation could be demonstrated between the postconstrictive dilation and the escape reaction. Both vascular adjustment reactions are of myogenic origin. It is concluded that the reason for the escape phenomenon can not be found in the local or propagated nerval response, in the transmitter release, or in its effect on the vascular smooth muscle. But it is suggested that the escape reaction is a form of myogenic, autonomic adjustment behavior.","PeriodicalId":78027,"journal":{"name":"Angiologica","volume":"10 5-6","pages":"233-47"},"PeriodicalIF":0.0,"publicationDate":"1973-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000157979","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15875497","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}

Small proportions of the 14C-radioactivity are incorporated into glycogen, glycosaminoglycans and lipids and are oxydized to 14CO2. Difference between the valves of the left ventricle (aortic and mitral valve) and of the right ventricle (pulmonary and tricuspid valve) were found in the rate of glycolysis as well as in the collagen, glycogen and glycosaminoglycan content. The in vitro incorporation of [U-14C] glucose radioactivity into the total glycosaminoglycans resulted in a specific labelling of hyaluronic acid, dermatan sulfate and chondroitin sulfate, but the specific radioactivities of the individual glycosaminoglycans and their relative rates of biosynthesis differed markedly. The relative rates of biosynthesis were 2.9–7.6 for hyaluronate, 1.0 for dermatan sulfate and 0.26–0.59 for chondroitin sulfate. After labelling the sulfated glycosaminoglycans with 35S-sulfate, the metabolic heterogeneity of dermatan sulfate and chondroitin sulfate was confirmed, but, in addition, heparan sulfate – not previously detected in heart valves – was identified as a third sulfated glycosaminoglycan. Chemical analyses of heparan sulfate revealed a sulfate/uronic ratio of 0.5; its relative amount was found to be 2–4% of the total glycosaminoglycans. Analogous chemical and metabolic data were obtained with chordae tendineae, except that a higher relative percentage of dermatan sulfate was found than in the corresponding heart valves.","PeriodicalId":78027,"journal":{"name":"Angiologica","volume":"10 3 1","pages":"129-41"},"PeriodicalIF":0.0,"publicationDate":"1973-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000157966","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64963181","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}
