  • Title: [Comparative studies of the vascularization of the posterior vena cava in some laboratory animals].
    Author: Khristova M.
    Journal: Eksp Med Morfol; 1976; 15(2):112-5. PubMed ID: 1278081.
    Abstract:
    The author examined the posterior caval vena in four various areas in a rat, guinea pig, rabbit, cat and dog by applying Indian inkgelatine injection and subsequent preparation of histologic and total brighter preparations. The established differences in the vascularization were determined by the thickness of the true venous wall. The later increased with an increase of the body of the examined kind of animal on behalf of the adventitial longitudinal muscular layer at comparatively small differences in the thickness of the circular muscular layer in the media. There were no capilearies in the adventicial muscular layer of a rat and guinea pig. This layer was vascular, when the thickness of the true venous wall surpassed 70 microns. The most deeply penetrated capillaries were located almost equaly from the vascular lumen: 25 microns in the rabbit and 30 microns in the cat and dog.
