Isolated bovine pulmonary arteries and veins were contracted subtnaxirnally and cumulative dose–response relationships to glyceryl trinitrate were obtained; the vein was approximately 10 times more sensitive than the artery to glyceryl trinitrate induced relaxation.
On a contracté sous-maximalement les veines et artères pulmonaires isolées de bovins et obtenu les relations dose–réponse cumulatives au trinitrate de glycéryle; la veine fut environ 10 fois plus sensible que l'artère à la relaxation induite par le trinitrate de glycéryle.
