[Functions of the small intestinal vessels during the cardiogenic depressor reflex and hyperthermia].
Cardiogenous depressor reflex in ambient hyperthermia decreased the perfusion pressure and increased the capillary filtration coefficient in the cat small intestine. Stretching ability and capacity of the small intestine veins were also increased in most cases. The vascular responses in hyperthermia developed with a longer latency and to a lesser extent. As the result of a decrease in the precapillary resistance and increase in the postcapillary one, the hydrostatic pressure raised in capillaries of the region under study indicating a fluid filtration in interstitium. Mechanisms underlying the shifts in the above functions, are discussed.
