Abstract

In 24 dogs light and electron microscopic changes of the neurohypohysis have been studied at early and intermediate periods of the prolonged compressing syndrom. The amount of neurosecrete has been stated to decrease considerably. Increased excretion of neurosecretory material from neurovascular zones is accompanied by mitochondrial swelling. Together with increased permeability of capillaries, disturbances in blood clotting system are demonstrated. With prolonged time of observations (intermediate period), further decrease of neurosecrete in axons and accumulating bodies is taking place. Some necrotic changes occur in endothelium.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
