Specified dysmorphic syndromes and CA-associations are registered on the basis of notification. Unspecified multiple congenital abnormalities are evaluated on the basis of notified abnormalities. First, a distance-diagnosis is being tried concerning some specified dysmorphic syndromes and CA-associations. Second, the alive babies with unspecified multiple abnormalities are referred to the regional multiple abnormality centre while a detailed post-mortem description is requested from the stillborns and infant deaths with multiple abnormalities. Third, the remaining unspecified congenital abnormalities are divided into 4 categories (obvious, important, dubious and minor) and into 40 groups. Babies with two abnormalities are annually compiled in one table. Babies with three abnormalities are summarized according to the so-called \"cardinal\" abnormalities in different tables. Finally, babies with four or more abnormalities are listed one by one with regard to the leading abnormality in another table. This classification system helps - among other - to recognize known and new syndromes and CA-associations, as well as to monitor a cluster of specific combinations of congenital abnormalities.</p>","PeriodicalId":72058,"journal":{"name":"Acta morphologica Academiae Scientiarum Hungaricae","volume":"29 4","pages":"377-90"},"PeriodicalIF":0.0,"publicationDate":"1981-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18352176","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}

Sympathetic innervation of the urinary bladder. 膀胱的交感神经支配
E Fehér, J Vajda

In the normal state adrenergic fibres could be found along the blood and lymph vessels, within the muscle layers and synaptizing on the surface of the local nerve cells or with other, probably local nerve processes. After extirpation of the hypogastric ganglia, degenerated axons could be observed in the local ganglia and in the connective tissue of the vessels. Many fluorescent fibres could be observed in the muscle layers, too. Four to six weeks after the operation, the animals were treated with 6-hydroxydopamine and no fluorescence was observed. In the muscle layer several degenerated fibres could be found, occasionally in close relation to the smooth muscle cells. It was therefore supposed that part of the sympathetic nerves originates from the hypogastric ganglia and is responsible for the modulation of the local ganglia and the blood supply of the urinary bladder. The other part emanates from the \"short adrenergic neurons\" and may effect directly the smooth muscle cells.</p>","PeriodicalId":72058,"journal":{"name":"Acta morphologica Academiae Scientiarum Hungaricae","volume":"29 1","pages":"27-35"},"PeriodicalIF":0.0,"publicationDate":"1981-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17848779","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}
