title: [Blood vessels and nerve apparatus of the heart and small intestine during continuous experimental bypass shunting].
abstract: In 140 animals (mongrel dogs of different age and sex) by means of histological, neurohistological, histochemical, histoenzymatic and electron microscopic methods, character and dynamics in changes of nerve elements and blood vessels of the heart and the small intestine have been studied under the conditions of revascularization at aorto-coronary and aorto-mesenteric shunting. The changes revealed are mainly reactive in their character, perform defensive, compensatory-adaptive response of the organs to the orative trauma and to an adequate but slightly changed blood stream. The degree of acuteness and the time when these changes disappear depends on duration of postocclusive ischemia, on the organs' resistivity to its effect on the operative trauma. Operation of aorto-coronary and aorto-mesenteric shunting are rather effective and protect the vascular bed and the intramural nerve appratuses of the heart and the small intestine from severe destructive disorders developing as a result of occlusion in the arterial vessels.
