Some parameters of lipid and lipoprotein metabolism in blood serum and liver of 4 and 20 weeks aged male hamsters in the norm and under high-caloric diet are investigated. It has been shown that the lipid profile of a blood plasma is degraded with aging in males, that expresses in an increase of the contents of FFA and triglycerides and a decrease of the HDL-cholesterol level. Under the use of a high-caloric diet, atherogenic dyslipidemia, which expresses in an increase of the levels of hypertriacylglycerolemia and apo-B-lipoproteins and a decrease of the HDL-cholesterol level, develops in experimental animals irrespective of age. 2008-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/4953 Вплив піридину на активність мембранозв’язаних ферментів клітин печінки Філінська, О.М.; Лозовий, В.П.; Яблонська, С.В.; Островська, Г.В.; Рибальченко, Т.В.; Зеленюк, В.О.; Рибальченко, В.К. Pyridine does not provoke significant changes of the ecto-ATPase and 5′-nucleotidase activities of the plasma membrane of hepatocytes. Mg2+, Ca2+-ATPase activity is not changed under the influence of pyridine too. Pyridine produces the alterations of the Na+, K+-ATPase activity that have biphase character. A decrease of the enzyme activity is observed at nanomolar and 10−5 M concentrations and disappears at micromolar concentrations. This effect might be caused by features of the pyridine interaction with the membrane lipid matrix. 2008-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/4952 Ефект ацетил-L-карнiтину на мiтохондрiальну функцiю та вивiльнення серотонiну при цукровому дiабетi Кучмеровська, Т.М.; Шиманський, I.О.; Донченко, Г.В.; Янiцька, Л.В.; Копелевич, В.М.; Клименко, А.П. A close relation between the impaired energy metabolism and the serotonin release from isolated synaptic terminals is established. These data suggest a substantial role of mitochondria in the derangement of the synaptic function associated with diabetes. Positive neuromodulatory role of acetyl-L-carnitine on the serotoninergic system is found. It is most likely to be mediated by it’s normalizing effect on the energy metabolism. 2008-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/4951 Особливостi видiлення етилену мiжвузлями кукурудзи (Zea mays L.) Щербатюк, М.М.; Маменко, Т.П. The intensity of ethylene emission in growing maize stem internodes is studied. The most intensive ethylene biosynthesis in maize internodes is ascertained for the early stages of development (5 leaves), and the least intensive one - for older stages (a flowering of panicle). So, during the maize development, the high and low levels of ethylene accumulation are typical of, respectively, rapidly growing top internodes and lower internodes. 2008-01-01T00:00:00Z
