Abstract:
In the present study, 10 healthy adult dogs were used,8 for the experimental group and 2 for the normal group. We observed the histochemical and ultrastrac- tural changes of the enzymes in the pyramidal cells in the cerebral cortex under the condition of acute ischemia. The result demonstrated that the activity of LDH, AcP and AchE was increased, while the activity of SDH, MAO, ATP ase was decreased. The ultrastructural chnges showed that in the acute ischemia gromp, there were enlargement perinucleus spaces of neurone, brisement, disappearance and vasicularization of the mitochondrial crista. This indicated that acute ischemia had an obvious effect on the histochcmistry of enzymes and the ultra- structure of the neurone in the cerebral cortex.
