[Mechanism of action of hydroxycoumarin derivatives].

Experimental and clinical studies have demonstrated the effects of hydroxycoumarin derivatives (pelentan) on the composition and correlation of phospholipids (PL) in red cell biomembranes. PL such as cardiolipin, cholesterol and its esters phosphatidylethanolamine, and phosphatidylcholine experienced the greatest changes. The changes in the composition of biomembrane PL were accompanied by an increase in the total cholesterol content in red cell biomembranes and by an increase in the total and free non-esterified fatty acids in blood plasma (P less than 0.05). At the same time the changes were discovered in the activity of transketolase and glucose-6-phosphate dehydrogenase limiting the pentosephosphate shunt.

[Effect of protein synthesis inhibitors on the vicasol-induced change in the content of the thermostable antifactor Xa in the blood serum].

Content of a thermostable inhibitor of thrombinogenesis (antifactor Xa) was decreased in blood serum after administration of pellentan. Subsequent treatment with vicasol normalized at the accelerated rate the antifactor Xa content in blood serum. Administration of the inhibitors of protein synthesis (vincrystine, actinomycin D, toyomycin, tetracycline--inhibitors of RNA polymerase, elongation, posttranscriptional conversions of mRNA and of translation processes, respectively (did not alter distinctly the vicasol effect--decrease in antifactor Xa content of blood serum. Vitamin K appears to participate in formation of the active molecule of the inhibitor of thrombinogenesis at the postribosomal step as shown in study of several other blood plasma procoagulants.

[Relation between ascorbic acid metabolism and the body' supply of vitamin K].

Experiments on rats were made to study the content of ascorbic (AA), Dehydroascorbic (DAA) and diketogulonic (DKGA) acids in the blood serum, daily urine, liver, adrenal, kidney, spleen and lung tissues under varying body supply with vitamin K. The rats with vitamin K deficiency manifested the decreased content of AA, DAA and the elevated content of DKGA in the blood serum, daily urine and test tissues. The percentage of AA absorption by blood proteins was found to be increased upon vitamin K deficiency in the body. The changes in AA metabolism correlated with the reduced capillary resistance. Administration of AA to rats with vitamin K deficiency led to an increase in the content of AA, DAA and to a lowering of DKGA in the blood serum and tissues promoting the normalization of capillary resistance. The data obtained attest to the dependence of AA metabolism on the body supply with vitamin K, pointing to the necessity of exercising the control over AA metabolism in different forms of vitamin K deficiency.
