The method is suitable for electron microscope study of DNA template activity. Activity of gen was compared in surface bound and subendothelial and in nonadhesive endothelial cells bound to monocyte. Acridine orange positivity, indicative of genic activity, was not found in few monocytes adhered in arteries of normotensive animals, while 62% of adhesive monocytes of hypertonic and 86% of ones accessed to endothelial space contained the products of acridine-orange-chromatin reaction in its nuclear, showing with it the gene derepression quickly ensuing in acute hypertensive vascular lesions. Only 2% of endothelial cells of pseudo-operated normotensive animals showed acridine orange positivity, while 17% of endothelial cells of hypertonic animals were positive. In the latter animals, 57% of endothelial cells showed acridine orange positivity, if monocytes adhered to their surface. In 84% of monocyte-endothelial pairs connected to each other, the nuclei have activity of same sign. Results show intensive activation of genes of monocytes in relation with adhesion and migration to vascular wall. Presumably, both hypertonia and monocyte adhesion have contributed to the increase of template activity of endothelial cells.</p>","PeriodicalId":19047,"journal":{"name":"Morphologiai es igazsagugyi orvosi szemle","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13555359","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}

At beginning of neurula stage, when also somites appear, the cardiogenic mesoderm forms into tissue of epithelial type and cardiac plate is developed in wall of pleuroperitoneal cavity. In conjugated cardiac plate, primordial cardiac cavity fundaments appear in the about 30-hour old chicken embryo with 6-7 somites. First myoblasts (and spontaneous action potentials) can be observed in the ventricular part of embryos with 7 somites. Hence, muscular differentiation is expanded to atrial section. In embryo with 9-10 somites straight cardiac tube is developed, its ventricular section pulsates feebly, but it is unable for blood circulation yet. Pacemaker tissue of cardiac tube is in the atrium. At the end of second day the first curvature of heart appears and myocytes of venous sinus become pacemaker. At the end of neurula stage the blood circulation starts in two-day old embryo with 16 somites. Development of heart of mammalian embryos differs in several aspects from cardiac development of avian ambryos. In mammals transformation and differentiation of cells in cardiac plate and primordial cardiac fundaments have a cranio-caudal trend and in nearly same developmental stage as in chicken. In mouse circulation is started by curved cardiac tube of embryo with 10-12 somites (eight and half day old) at the end of neurala stage.</p>","PeriodicalId":19047,"journal":{"name":"Morphologiai es igazsagugyi orvosi szemle","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1989-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13735783","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}
