I-6: Remodelling Uterine Spiral Arteries inPregnancy
Background: During the first trimester of pregnancy the uterine spiral arteries that supply blood to the placenta are remodelled, creating heavily dilated conduits lacking maternal vasomotor control. To effect permanent vasodilatation, the internal elastic lamina and medial elastic fibres must be degraded. Failure of remodelling is a key characteristic of the pathological placenta and is though...
متن کاملRelation between coronary artery remodelling (compensatory dilatation) and stenosis in human native coronary arteries.
OBJECTIVES To investigate the contribution of plaque size and vessel remodelling to coronary artery stenosis and to assess the role of vessel shrinkage (negative remodelling) across a wide range of lesions. DESIGN Postmortem study of coronary remodelling in perfusion fixed hearts. SUBJECTS 24 men and 24 women who died suddenly with coronary artery disease. MAIN OUTCOME MEASURES Percentage...
متن کاملEvaluation of the Patency Rate of the Coronary Arteries after Treatment with Heberkinase
Background: Intravenous thrombolytic therapy is still the most common treatment for acute myocardial infarction (AMI) in our country. In recent years, some cases of suboptimal results of the treatment with a special trademark (Heberkinase) have been reported. So, we decided to evaluate the patency rate of arteries involved in infarction after treatment with Heberkinase. Materials and Methods:...
متن کاملPig Coronary Arteries
Arterial smooth muscles behave like a syncytium, since they are electrically coupled. It is generally assumed that electrical coupling and dye coupling are mediated by gap junctions. No gap junctions could be detected by transmission electron microscopy in media of coronary arteries. We looked for the presence of gap junction protein in vascular smooth muscle by immunohistochemistry with light ...
متن کاملCoronary Arteries In Vivo
a specific inhibitor, the hypothesis that acetylcholine-induced coronary vasodilation is due to EDRF release was tested. Methods and Results. We studied the response of normal coronary arteries to acetylcholine (an endothelium-dependent vasodilator) and isosorbide dinitrate (an endothelium-independent vasodilator) in seven patients. The specificity of any vasodilator response was assessed by th...
