    Abstract Aim      To study the effect of arterial hypertension (AH) in combination with frequent alcohol consumption on the formation of risk for cardiovascular death and all-cause death according to results of a 27-year prospective cohort study.Material and methods  This 27‑year prospective cohort study of an unorganized population of the Tomsk city (1546 people aged 20-59 years, including 630 men and 916 women) investigated AH prevalence and alcohol consumption (1988-1991) and analyzed the predictive significance of the effect of AH in combination with frequent alcohol consumption on the formation of risk for all-cause and cardiovascular death. AH was diagnosed at blood pressure ≥140 / 90 mm Hg. Frequent alcohol users were defined as those who consumed alcohol more than once a week.Results The combination of AH and frequent alcohol consumption increased the risk of all-cause death 4.1 times compared to that for persons without these risk factors (p<0.001). This was true for all age groups of the total cohort (higher relative risk, RR, was observed for persons aged 20-39 years) and for men (except for the group aged 40-59 years). RR of cardiovascular death was 5.3 (p<0.001) for frequent alcohol users with AH. It was established that frequent alcohol consumption additionally increased RR of all-cause death for persons with AH (RR 1.89; p<0.05) primarily at the expense of persons aged 20-39 years. Prediction of 27‑year survival for frequent alcohol users with AH was 35.3 %.Conclusion      A combination of AH with frequent alcohol consumption considerably increases the risk of all-cause and cardiovascular death. Frequent alcohol consumption significantly impairs the prediction of 27-year survival for persons with AH by additionally (1.9 times) increasing the risk of all-cause death. Binary AH combinations with frequent alcohol consumption exert a more pronounced adverse effect on young men and women.

    Title translation Uncoupling of the liver monooxygenase system by perfluorocarbons in vivo.
    Abstract Administration of a perfluorodecalin (PFD) emulsion, the liver cytochrome P-450 II B1/B2 inducer, to experimental animals is followed by a two-fold increase of the NADPH oxidation rate in liver microsomes. This phenomenon is caused by the presence in the cytochrome P-450 active center of PFD which uncouples microsomal hydroxylation. The high rate of NADPH oxidation in liver microsomes after administration of the fluorocarbon does not decrease the level of reduced pyridine nucleotides in the liver and does not change the glucose concentration in the plasma. It is suggested that the accelerated weight loss in starved animals following PFD administration is due to the energy dissipation in the fluorocarbon uncoupled monooxygenase reactions in the liver.

    Title translation Viscosity of free and protein-bound lipids in membranes.
    Abstract Structural transitions induced by temperature in the lipid bilayer of rabbit sarcoplasmic reticulum membranes have been detected by means of the hydrophobic fluorescent probe pyren. Using the phenomenon of energy migration from membrane protein tryptophan residues to pyren a correct estimate of lipid viscosity near protein molecules was made by an empirical formula. The structural transitions of free and protein-bound lipids proceeded at the same temperature intervals. It was found that viscosity of protein-bound lipids was higher than that of free lipids, but they became equal at 36--39 degrees C.

    Abstract Preclinical studies comparing perflubron partial liquid ventilation with conventional mechanical ventilation have indicated that perflubron partial liquid ventilation may exert some anti-inflammatory effects. To assess whether these effects were related to the lipid solubility properties of perflubron rather than to nonspecific biophysical properties of the perfluorocarbon (PFC) liquid phase, we studied the effects of PFCs with varying lipid solubilities on the platelet aggregation response to various procoagulants and the erythrocyte hemolytic response to osmotic stress. In both cases, the degree of the response was directly related to the lipid solubility of the PFC. All the perflubron content of erythrocytes was found to be associated with the membrane compartment. The time to reach a maximum effect on hemolysis with perflubron was relatively slow (2-4 h), which paralleled the time for perflubron to accumulate in erythrocyte membranes. The rate and extent of perflubron partitioning into lecithin liposomes were similar to those of erythrocyte membranes, supporting the hypothesis that perflubron was partitioning into the lipid component of the membranes. Thus some of the potential modulatory effects of perflubron on excessive inflammatory responses that occur during acute lung injury and acute respiratory distress syndrome may be influenced in part by the extent of PFC partitioning into the lipid bilayers of cellular membranes.
