[Features of lung tissue cell membrane lipid composition under acute emotional stress in rats].

The lipid composition of the lung plasmatic membrane in rats which have been under the acute emotional pain stress action is studied. These results are compared with the control group of animals. It is shown that at acute stress the changes of lipid composition of the lung plasmatic membranes are manifested in decrease the phospholipids and increase of cholesterol levels. The correlation of phospholipids/cholesterol in plasmic membranes in the lungs decreases at stress. At the same time the decrease of triglyceroles and diglyceroles contents is observed as well as the increase of fat acids' number. The changes that take place in the lipid contents of the lung plasmatic membranes at acute stress can play an essential role in the mechanism of cell damage development.
