Abstract
In acute experiments on SHR and WKY rats, the pial arterioles' myogenic responses to a drop in systemic blood pressure (SBP) were studied. The SHR seem to be more capable of keeping the myogenic activity in low SBP. It might depend on structural changes in the vascular wall under these conditions wall in the SHR.
摘要
在对自发性高血压大鼠（SHR）和正常血压大鼠（WKY）的急性实验中，研究了软脑膜小动脉对体循环血压（SBP）下降的肌源性反应。SHR似乎更有能力在低SBP状态下保持肌源性活动。这可能取决于SHR在这些条件下血管壁的结构变化。
