Abstract
- The hyperthermic effect of intramuscular NA at 32 degrees C was abolished by propranolol but not by phentolamine preinjection. 2. The lack of hyperthermic response was at least partly due to the blocking effect of propranolol on beta-receptor mediated in heart rate. 3. After NA the respiratory rate was gradually increased in birds preinjected either with propranolol or with phentolamine.
摘要
- 32摄氏度下肌肉注射去甲肾上腺素（NA）的升温效应被普萘洛尔消除，但预先注射酚妥拉明则无此效果。2. 缺乏升温反应至少部分归因于普萘洛尔对心率中β受体介导作用的阻断效应。3. 注射NA后，预先注射普萘洛尔或酚妥拉明的鸟类呼吸频率逐渐增加。
