Openings in frog microvascular endothelium at different rates of increase in pressure and at different temperatures.

Experiments were carried out on single mesenteric capillaries and venules of pithed frogs to determine whether the rate of increase in intravascular pressure (dP/dt) influenced the critical pressure (P(B)) which increases wall permeability. Vessels, microperfused with frog Ringer solutions containing 0.1% bovine serum albumin and red cells, were occluded… CONTINUE READING
