[Function of the mononuclear phagocyte system after administration of emulsions of perfluorinated carbon compounds].

Morpho-functional characteristics of mononuclear phagocyte system (MPS) have been studied in experimental animals upon the infusions of perfluorocarbon (PFC) emulsions. It has been established that the infusion of high doses of PFC emulsions following massive hemorrhage causes the reduction in the histoenzymatic activity in MPS of PFC-accumulating organs. Low doses of PFC emulsions increase histochemical activity in PFC-containing macrophages, suggesting a stimulating effect of PFC emulsions on MPS.

[Effect of perfluorocarbon emulsions on the protective properties of cardioplegic solutions].

The influence of ischemia and conventional and emulsion cardioplegia on the dynamics of resting tension, Ca2+ concentration, the level of membrane potential and oxygen tension in the myocardium was studied. It was shown that emulsion cardioplegia prolonged the duration of anoxic protection due to the additional oxygen supply of tissues and the decrease in Ca2+ cytoplasm accumulation.
