  • Title: [Effect of temporal disturbance of the blood flow on the structure of neurons of the myenteric plexus].
    Author: Liubaev VA.
    Journal: Arkh Anat Gistol Embriol; 1982 Nov; 83(11):70-6. PubMed ID: 7165520.
    Abstract:
    The dynamics of changes occurring in the myenteric plexus neurons have been followed in 230 mature cats from the first step up to the 120th day after 1-, 2.5-, 4-, 6-, 8-hour's disturbance in the arterial and venous blood circulation using Bielschowsky--Gros, Nissl and Nachlas techniques. Depending on duration of the ischemia and the postischemic period, various amount of unchanged neurons and neurons having certain reactive and destructive changes have been revealed. During all the periods of the investigation, certain differences are noted in the reaction both of all the ganglia and single neurons within one ganglion. Some neurons demonstrate certain resistivity to the prolonged disturbance in the blood flow. By means of the polarography method, the dynamics of changes in the oxygen strain in tissues of the experimental area of the small intestine after the arterial and mixed ischemia have been studied. An elevated oxygen strain has been revealed in the tissues under conditions of venous congestion and an attempt has been made to explain this effect.
