Gamma-Glutamyl Transpeptidase Activity in the Developing Rat Testis. Enzyme Localization in Isolated Cell Types

Abstract

The anatomical descriptions of the vasculature of the uterus and ovaries in rhesus monkeys do not provide quantitative information about the relative contributions of the ovarian and uterine arteries to the blood supply of the reproductive tract. To identify the major source of arterial blood supply to these organs under varying reproductive conditions, monkeys were studied during nonpregnant (n = 7), early pregnant (Days 13-18, n = 6), and late pregnant (Days 149-154, n = 4) states. Microspheres, labelled with different isotopes, were injected simultaneously into the left ventricle and the aorta midway between the origin of the ovarian artery and the terminal bifurcation of the aorta. The resulting ratio of microspheres in various organs or segments of the reproductive tract was indicative of the source of arterial blood.
