大白鼠共60只,以戊巴比土鈉及巴比土鈉腹腔內注射麻醉(剂量:戊巴比土鈉50毫克/公斤体重,巴比土鈉250毫克/公斤体重),記录其颈总动脈血压、气管呼吸。夾另一側頸总动脈以引起頸动脈竇升压反射,或者阻断頸內、頸外动脈,提高竇內压,以引起頸动脈竇降压反射;用100W的电灯一只,置于大白鼠腹部上方約15厘米处,作为加溫热源。大白鼠体溫升高速度大約为每10分钟升高1℃。 夾頸总动脈时,除了引起血压上升的反应外,也有上升下降交替的双相反应和
A total of 60 rats were anesthetized by intraperitoneal injection of sodium pentobarbital and sodium barbiturate (dose: 50 mg / kg body weight sodium pentobarbitol, 250 mg / kg body weight sodium barbiturate), and the neck Total arterial pressure, tracheal respiration. Clip the other side of the common carotid artery to cause reflex in the carotid sinus, or block the carotid and external carotid artery, increase sinus pressure to cause antihypertensive reflex in the carotid sinus; with a 100W electric lamp , Placed in the abdomen about 15 cm above the abdomen, as a warming heat source. Rat body temperature increases about 1 ℃ every 10 minutes. Common carotid artery, in addition to causing the rise in blood pressure response, there are alternately rising and falling biphasic response and
