本文研究了可乐定(Clonidine)的降压作用原理。实验用29只猫,以戊巴比妥钠麻醉,记录血压和心率,按 Feldberg 和 Guertzentein 提出的给药方法,在桥脑下面的正中线两侧各安置1个塑料环,每个环内放入药液10微升,轻压使环固定,并使药物作用于锥体外侧和斜方体后侧的延髓腹面上,每次给药后均用人工合成的脑脊液冲洗延髓表面。 This article studies the antihypertensive principle of Clonidine. In the experiment, 29 cats were anesthetized with sodium pentobarbital, blood pressure and heart rate were recorded. According to the method proposed by Feldberg and Guertzentein, a plastic ring was placed on each side of the midline of the pons under the pons and each ring was placed Into the liquid 10 microliters, gently press the ring fixed, and the drug acting on the outer side of the cone and the rostral body medulla oblongata on each side, after each administration of synthetic cerebrospinal fluid rinse the medulla oblongata surface.
