Abstract:
Non-pulsed optical density of the small intestine was studied in 32 dogs and the results were compared with the data of angiotensometry and pulsomotorography. New regularities of blood circulation in the small intestine were detected: more than half of the total volume specific blood flow in the intestinal tissue is normally realized in vessels at a pressure below 40 mm Hg. An additional criterion of viability of the small intestine during ischemia is developed.
