[The effect of acidic metabolic products on the capacitance and resistance vessels of the skeletal muscles and intestines]. 1975

L A Vil'de

Under conditions of the resistography of the skeletal muscle and intestinal vessels intraarterial injections of the acetic and lactic acid solutions in 75% cases evoked significant dilatation of the resistance vessels. Simultaneously enhancement of the venous outflou takes place, which is determined mainly by venous constriction and partly by the transfer of liquid from tissues into the blood. The rise of the venous outflow was lasted for 45 sec. and for 90 sec. in several experiments. This was not observed by the intraarterial injection of hypertonic solutions of NaCl Glucose, MgSO4 and others. The reactions of capacitance vessels was not dependent on the reactions of resistance vessels since the rise of the venous outflow took place also when only constriction of the resistance vessels (8 experiments) or when constrictor-dilatator reactions of the resistance vessels were observed.

D001808 Blood Vessels Any of the tubular vessels conveying the blood (arteries, arterioles, capillaries, venules, and veins). Blood Vessel,Vessel, Blood,Vessels, Blood
D002415 Cats The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.
