[Comparative characteristics of myogenic responses in pial arterioles in normotensive and spontaneously hypertensive rats].
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.
