WebThese findings suggest that the mTAL is exquisitely susceptible to anoxic damage because of low O2 supply imposed by the medullary vascular system and the high rate of … WebThe adrenal medullary hormone epinephrine is one of the best-studied examples of hormonal modulation of learning and memory. Posttraining injections of epinephrine enhance memory for a wide range of tasks in experiments with rats and mice. The enhancement follows an inverted-U dose-response curve, in which high doses can …

WebStage IV--Medullary Paralysis. This stage begins when the anestheticdepresses the medulla. Respiration becomes shallow and irregular resulting in anoxia (lack of oxygen) in the tissues. The skin first becomes pale and then cyanotic. This is the stage of cardiac and respiratory paralysis and death. WebMedullary hypoxia is an obligatory part of the mechanisms of renal conservation of water, and it poses a constant threat to cellular integrity in this region of the kidney. In the course of...

Web1 mei 1987 · Abstract Na+-K+-ATPase activity was measured in a suspension of rabbit medullary thick ascending limb tubules under oxygenated and anoxic conditions. Oxygenated, K-depleted tubules rapidly take up added extracellular potassium accompanied by a simultaneous increase in oxygen consumption. WebA specific anatomical lesion sharply localized to the cells of the medullary thick ascending limbs (mTAL) and characterized by mitochondrial swelling progressing to nuclear pyknosis and
