title: [Engorgement of the adrenal cortex of intact white rats and of those subjected to acute overheating].
abstract: In 40 white female rats, intact and subjected to overheating at 45 degrees C for 1 h (the body mass 160 g), three stages of blood filling have been revealed in the adrenal cortical substance: hyperemia, moderate blood filling and ischemia. In conformity with them the adrenal mass thickness of their cortical substance and the functioning capillary areas, spongiocytes size and content of ascorbic acid undergo certain changes. It is possible that the variants of blood filling and corresponding to them the morphofunctional indices are certain stages of a single microcirculatory and functional cycle which consists of 4 phases: vasodilatation to vasoconstriction, vasoconstriction and transmission from vasoconstriction to vasodilatation. In the rats subjected to overheating the vasodilatation phase is more pronounced.
