[Effect of bradykinin on blood circulation in the human celiac artery bed].
Selective angiography and direct measurements of the arterial pressure in the celiac artery was used to study the influence of bradykinin on the blood circulation in healthy organs in the celiac region in 24 patients. A high sensitivity of the vessels to the action of bradykinin (0.1--10 mkg) was revealed: it decreased the blood pressure, increased the rate of blood flow, increased the diameter of arterial and venous vessels, arterio-venous anastomosis, increased the number of functioning capillaries. No differences were found in the reaction of the vessels of the liver, spleen pancreas, duodenum and the stomach to bradykinin.
