Abstract:
The 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 izolate
