  • Title: [Influence of preliminary conditioning to gravitational overloading and subsequent exposure to a series of extreme factors on the intra-organ blood flow of the intestine].
    Author: Nikitin MV.
    Journal: Arkh Anat Gistol Embriol; 1977 Apr; 72(4):44-9. PubMed ID: 901195.
    Abstract:
    The intraorganic blood circulation bed of the intestine was studied in 21 rabbits subjected to training to gravitation stresses (according to special schedules) and then to maximum endurable gravitation stresses, hypokinesia for 4 weeks and repeated stresses of the direction and character similar to those at the beginning of the experiment. The direction of stresses was different: head--pelvis, pelvis--head, chest--back. Injection of the intestine blood vessels with the Gerota's mass followed by clearing after A. M. Malygin, histological staining after Van Gieson and method of luxmetry were used. Preliminary training to stresses considerably prevented anatomical alterations in blood vessels of the intestinal coats. The most favourable morphological picture was observed in the cases when the stress was of ventro-dorsal direction. Blood vessels of the large intestine were more inert in their transformation than those of the small intestine coats.
