  • Title: [Effect of vasocative substances on resistance and capacitance vessels under high altitude conditions].
    Author: Daniiarov SB, Kononets IE.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1979 Dec; 65(12):1825-32. PubMed ID: 42566.
    Abstract:
    In cats, i.a. administration of adrenaline (10 microgram), serotonin (30 microgram), and acetylcholine (10 microgram) on the 3rd, 15th, and 30th days of animals stay at 3200 m altitude induced different vasomotor responses in precapillary and postcapillary portions of intestine vascular net during different periods of high altitude adaptation. Changes of reactivity in different receptor structures of smooth muscles, the initial tonus of the small intestine resistance vessels associated with the whole adaptive rearrangement of the organism functional state in the high altitude extreme conditions, are the possible mechanisms of detected changes.
