Effect of alveolar hypoxia on reactivity of pial vessels in normotensive and spontaneously hypertensive rats.
Intravital television microscopy revealed reduced reactivity of pial arterioles in response to alveolar hypoxia in spontaneously hypertensive rats (SHR) compared to normotensive (WKY) rats, which manifested in decreased number of dilatory reactions and in less pronounced vascular dilation.
