[The role of actual demographic trends in improving state health policy].

The decreasing of demographic security level is a global social economic trend in both developed and developing economies. Hence there is an urgent need in improving state social policy, including health care. The key target of this study is to evaluate the role of modern demographic trends in improving state social economic policy in health care. The study characterizes demography role in developing state health care strategy and to assesses world demographic trends that permitted to formulate potential barriers and obstacles in achieving stable level of demographic security. The distinctive features of modern demographic trends in Russia were identified and used as a background in developing prospective ways of improving state health policy in Russia with specific focusing on identified identified predicaments in national demographic development. The interdisciplinary analysis was applied in the field of theory and practice of health demography as a new scientific area as well as systemic and economic analysis. The most important result of the study was the established need in assessing relationship between current national demographic situation and economic efficiency and social economic consequences for whole society that actualized retrieval and elaboration of relevant social economic indices of life quality within the framework of health demography.

The regulation of rat brain pyruvate kinase by estradiol-17 beta.

The effect of estradiol-17 beta on the activity of pyruvate kinase from rat brain was investigated at initial stages of hormone administration. After estradiol treatment the rise of pyruvate kinase activity was found in the firmly bound synaptosomal fraction, whereas pyruvate kinase activity in soluble and weakly bound fractions has been reduced. The activation of the enzyme was also discovered after glutaraldehyde fixation on synaptosomal membranes. The possible mechanism of extragenomic estradiol action is discussed.
