[Effect of cooling on liver phospholipids].

Phospholipid composition of rat liver tissue was distinctly altered in cooling. Single-term cooling caused a decrease in content of phosphatidic acids, cardiolipin, phosphatidyl diethanolamine, phosphatidyl serine but it increased the sphingomyelin level. Content of phosphatidyl choline and of lysolecithins was markedly decreased in short-term cooling. Prolonged cooling was accompanied by an increase in content of all the phospholipid fractions except of phosphatidyl choline. Appearance of monophosphoinositide in the phospholipid spectrum under all the conditions studied reflect the response of the organism to a stressing influence of cooling.
