Lipid composition of rat somatic nerves under the effect of damaging factors.

Ligation of the sciatic nerve in rats led to reversible decrease in excitability and changes in lipid composition of myelinated nerve fiber: increase in the content of lysophosphatidylcholine, lysophosphatidylethanolamine, and free fatty acids and phospholipase A2 activity. Xymedon and laminin accelerate nerve regeneration and restore its lipid composition.

Study of changes in diacylglycerol content on nerve excitation.

Rhythmic excitation of a rabbit myelin nerve increased diacylglycerol (DAG) content from 1.53 to 2.17 microg/mg lipids.

Effect of hydrogen peroxide on ejection of cell nucleus from pigeon erythrocytes and state of membrane lipids.

The nuclei are ejected from the pigeon erythrocytes and apoptotic vesicles form in these cells in the presence of hydrogen peroxide. Hydrogen peroxide intensifies LPO processes and changes phospholipid content. The relative content of phosphatidylcholine, sphingomyelin, and phosphatidylserine decreased, while that of phosphatidylethanolamine and lisophosphatidylcholine increased.
