【摘要】 经颈内动脉恒速灌流测量大白鼠脑血管阻力,其结果如下:收缩压为90.4±4.99mmHg,脑血管阻力为84.1±5.9mmHg。注射去甲肾上腺素后可使这些值增加,而酚妥拉明可使这些值降低。更多还原

【Abstract】 The cerebral vascular resistences (CVR) of rats were measured by a constant-rate perfusion (1.82±0.17ml/min) apparatus. The results were as follows: system presure was 90.44±4.99mm Hg, and CVR was 84.1±5.9mm Hg. These values increased with intravascular injective of norepinephrine and decreased with phentolamine.更多还原
