Effect of chlorpromazine on sympathetic neuroeffector transmission in the rabbit isolated pulmonary artery and aorta.
1. The effects of chlorpromazine on sympathetic neuroeffector transmission have been studied in the rabbit isolated pulmonary artery and aorta. 2. Chlorpromazine (10(-8)-10(-5) M), prazosin (10(-9)-10(-7) M) and phentolamine (3 x 10(-8)-3 x 10(-5) M) decreased the contractions of pulmonary artery evoked by electrical field stimulation (150 pulses; 3 Hz). The rank order of inhibitory potency (ID...
متن کاملA case of isolated peripheral pulmonary artery branch stenosis associated with multiple pulmonary artery aneurysms.
Selective right pulmonary arteriography and 3-dimensional computed tomography revealed multiple severe stenoses of the peripheral pulmonary artery associated with poststenotic aneurysms in a 65-year-old woman. She was referred to the hospital for evaluation of dry cough, gradually increasing dyspnea and multiple nodular shadows on a chest radiograph. Echocardiography and cardiac catheterization...
متن کاملRelaxant effect of oxytocin on isolated human oviduct.
AIM Oxytocin produces concentration-dependent relaxation of isolated isthmus and ampulla of human oviduct precontracted by histamine. The aim of our study was to investigate whether this oxytocin effect was specific and by which receptors it was mediated. METHODS We investigated effects of oxytocin and its antagonists on isolated isthmus and ampulla of the uterine tubes from 20 women who unde...
متن کاملThe Relaxant Effect of Propofol on Isolated Rat Intrapulmonary Arteries
Propofol is a widely used anesthetic. Many studies have shown that propofol has direct effects on blood vessels, but the precise mechanism is not fully understood. Secondary intrapulmonary artery rings from male rats were prepared and mounted in a Multi Myograph System. The following constrictors were used to induce contractions in isolated artery rings: high K(+) solution (60 mmol/L); U46619 s...
