[Morphofunctional equivalents of the pituitary-adrenal system in disruptions of the integrity of the cardiorespiratory systems].
Desintegration of the cardio-respiratory apparatus activity was modelled in 8 dogs using an individually dosed loading (running in the treadmill) up to V stage according to the original technique (control--10 dogs). By means of morphometric, histological, histochemical and electron microscopic analysis, morpho-functional equivalents of the reaction of the hypophysis-adrenals system were studied at a repeated desintegration in the activity of the cardio-respiratory apparatus. It was demonstrated that certain elements of the hypophysis-adrenals system were completely involved into the adaptive reactions. The greatest functional activity was detected in chromophobic and basophilic adrenocytes and in cells of the glomerular zone. In cells of the fascicular zone and in the medullar substance of the adrenals peculiar signs of the functional activity appeared. It is not expedient to calculate training regimes basing on the loading which determines the state of desintegration in the cardio-respiratory apparatus activity.
