Pressures in the pial arterial microcirculation of the cat during changes in systemic arterial blood pressure.
Dynamic arterial blood pressures were recorded by micropuncture of 99 cortical surface arteries and arterioles in cats anesthetized with pentobarbital or chloralose and urediane, using the Wiederhielm servocontrolled micropipette pressure system incorporating pipette tips less than 0.5/A in diameter. During these measurements, systemic blood pressure was varied by supplemental intravenous admin...
متن کاملPerivascular potassium and pH as determinants of local pial arterial diameter in cats. A microapplication study.
The effects of and the interaction between local perivascular variation in potassium and bicarbonate concentration on the diameter of pial arteries were studied in cats by the microapplication technique. At 11 mEq/liter of bicarbonate, a direct correlation existed between vascular diameter and K + concentrations between 0 and 10 mEq/liter. At K concentrations between 10 and 20 mEq/liter, no fur...

متن کاملPial arterial pressure in cats following middle cerebral artery occlusion. II. Relationship to regional disturbance of energy metabolism.
Focal cerebral ischemia was produced in 16 cats by occluding the left middle cerebral artery (MCA) for 120 min. Cortical blood flow and pial artery pressure were determined prior to vascular occlusion and after 15, 60 and 120 min. At the end of the experiments (after 120 min MCA occlusion) heads were frozen in situ with liquid nitrogen. Cooled brains were cut into 0.5 cm thick slices. From thes...
