本文研究了侧脑室注射阿托品对大鼠蓝斑核加压反应的影响。其结果:1.给侧脑室注射阿托品(0.05~1.00mg)不引起血压改变;2.侧脑室注射阿托品(0.05—1.00mg)后,蓝斑核加压反应亦不发生改变。这提示中枢乙酰胆硷不参与蓝斑核兴奋所引起的加压反应。
This article studies the effects of intracerebroventricular injection of atropine on locus coeruleus pressure in rats. The results: 1. To the lateral ventricle injection of atropine (0.05 ~ 1.00mg) does not cause blood pressure changes; 2. Intracerebroventricular injection of atropine (0.05-1.00mg), locus coeruleus pressure response does not change. This suggests that the central acetylcholine does not participate in the pressure response caused by the excitation of locus coeruleus.
