Reflections about estimative method of the isolate portal vein contractility

Department of Physiology and Biophysics, State University of Medicine and Pharmacy, Chisinau, R. MoldovaThe current investigation intended to determine the conditions of portal vein contractions in rats in isometric regime. The proceeding of object preparation as well as experimental phases was described. Main parameters of contractility were highlighted, also the importance of portal vein muscle reactivity at different concentrations of Ca ions. Hypotheses about the origin and mechanism of portal vein muscle contraction were enounced. Prezenta investigaţie determină condiţiile contracţiilor venei porte la şobolan în regim izometric. A fost descrisă desfăşurat manopera de preparare de obiectului de studiu precum şi etapele experimentale. S-au evidenţiat indicii principali ai contractilităţii, cît şi importanţa reactivitaţii muşchiului venos portal la diferite concentraţii a ionilor de Ca2+. Au fost expuse ipoteze privind originea şi mecanismul contracţiei venei porte izolat
