The protein and phospholipid constituent in membrane of neurocyte in brain of chicken with encephalomalacia was separated and studied with the method of SDS-PAGE electrophoresis and the method of high performance-thin layer chromatography respectively The fluidity of neurocyte membrane of chicken with encephalomalacia was determined for the first time The content of Ca and trace elements were determined in chicken encephalomalacia systematically and the status of Fe ion in cerebellum was observed. The activity of enzymes that were relative to metabolism of energy and neuro-medium in brain were checked systematically with the method of enzyme-histochemistry. Pathological examination was carried out by microscopic and ultramicroscopic observation. The apoptosis of neurocyte in brain was checked.
