Introduction. Among noninfectious diseases, one of the leading places belongs to pathologies caused by the action of industrial toxicants. In this regard, the search for drugs for the prevention and treatment of various intoxications is one of the priority tasks of public health. Treatment of intoxication with drugs with antioxidant and antihypoxic activity is more effective. The aim of this study was to investigate morphological changes in parenchymal organs (liver, kidneys, and pancreas) under acute exposure to high doses of carbon tetrachloride and to evaluate the effectiveness of their correction with a new composition of oxymethyluracil with ascorbic acid. Material and methods. The composition of 5-hydroxy-6-methyluracil with ascorbic acid was first synthesized at the Ufa Institute of Chemistry, Ufa Federal Research Center, RAS. The preventive effect of the new drug was studied in comparison with “Heptor” on the carbon tetrachloride-induced liver injury model. Morphological studies of the liver, pancreas, and kidneys of laboratory animals were carried out. Results. Studies have shown the prophylactic administration of new composition of 5-hydroxy-6-methyluracil with ascorbic acid to have a protective effect on the structure of parenchymal organs in acute carbon tetrachloride intoxication, comparable to the drug “Heptor” (possibly superior). However, reparative properties were observed only in the drug “Heptor”. Conclusion. Comparative estimation of morphological changes in parenchymal organs under acute exposure to high doses of carbon tetrachloride indicates the protective effect of prophylactic administration of the composition of 5-hydroxy-6-methyluracil with ascorbic acid, comparable to the drug “Heptor” (possibly superior).

ABSTRACTPrevious research has shown that 1% to 10% of sessileCandida albicanscells survive treatment with high doses of miconazole (a fungicidal imidazole). In the present study, we investigated the involvement of sphingolipid biosynthetic intermediates in this survival. We observed that theLCB4gene, coding for the enzyme that catalyzes the phosphorylation of dihydrosphingosine and phytosphingosine, is important in governing the miconazole resistance of sessileSaccharomyces cerevisiaeandC. albicanscells. The addition of 10 nM phytosphingosine-1-phosphate (PHS-1-P) drastically reduced the intracellular miconazole concentration and significantly increased the miconazole resistance of a hypersusceptibleC. albicansheterozygousLCB4/lcb4mutant, indicating a protective effect of PHS-1-P against miconazole-induced cell death in sessile cells. At this concentration of PHS-1-P, we did not observe any effect on the fluidity of the cytoplasmic membrane. The protective effect of PHS-1-P was not observed when the efflux pumps were inhibited or when tested in a mutant without functional efflux systems. Also, the addition of PHS-1-P during miconazole treatment increased the expression levels of genes coding for efflux pumps, leading to the hypothesis that PHS-1-P acts as a signaling molecule and enhances the efflux of miconazole in sessileC. albicanscells.
