Morphofenotypes of constitution in obstetrics

The constitution of human and its morphological expression - somatotype is a determining factor in many physical and mental manifestations of human life. Constitution - a combination of morphological and functional characteristics of the organism, formed on the basis of inherited and acquired characteristics of an organism (B.A. Nikityuk, 1991, 2000). Morphofenotype constitution (somatotype, somatic type, somatotype) is the most accessible to study, relatively stable during ontogenesis and genetically determined characteristic of the integrity of the organism. Recently, our country has received widespread use method of determining somatotype R.N. Dorokhov (1985, 1991). So do not lose their relevance research somatotype characteristics of man, which significantly affects, in the future, to pregnancy and childbirth. The purpose of this study was to study the characteristics of pregnancy in women with different somatotypes

Quasilocal Conservation Laws: Why We Need Them

We argue that conservation laws based on the local matter-only stress-energy-momentum tensor (characterized by energy and momentum per unit volume) cannot adequately explain a wide variety of even very simple physical phenomena because they fail to properly account for gravitational effects. We construct a general quasi}local conservation law based on the Brown and York total (matter plus gravity) stress-energy-momentum tensor (characterized by energy and momentum per unit area), and argue that it does properly account for gravitational effects. As a simple example of the explanatory power of this quasilocal approach, consider that, when we accelerate toward a freely-floating massive object, the kinetic energy of that object increases (relative to our frame). But how, exactly, does the object acquire this increasing kinetic energy? Using the energy form of our quasilocal conservation law, we can see precisely the actual mechanism by which the kinetic energy increases: It is due to a bona fide gravitational energy flux that is exactly analogous to the electromagnetic Poynting flux, and involves the general relativistic effect of frame dragging caused by the object's motion relative to us.Comment: 20 pages, 1 figur

The wind regime of the mesosphere and lower thermosphere during the DYANA campaign-I. Prevailing winds

During the DYANA campaign, winds and tides at mesospheric and lower thermospheric altitudes were measured by 14 ground based experiments (MF radars, meteor radars and LF-drift systems). The experiments were located between 107°W and 102°E, mostly in northern mid-latitudes with well covered areas in Central and Eastern Europe. Emphasis is placed here upon the vertical profiles and height-time contours of the prevailing zonal and meridional winds with different resolution (15 d, 4d). Generally, westerly winds are observed at heights below 95 km with a strong mesospheric variability and with longitudinal differences between the data of Central Europe, Eastern Europe, Asia and Canada. Planetary waves and a minor stratospheric warming in the first 10 days of February 1990 are the cause of this behaviour. In connection with the stratospheric warming, a wind reversal to summer east winds reaching from the upper stratosphere up to 95 km is observed. The close connection of the behaviour of the stratosphere with the observed longitudinal differences in the mesospheric response on the stratospheric warming and with the occurrence of wind oscillations (10-15 d) is discussed. © 1994

COMPARATIVE ANTICONVULSANT AND ANTIHYPOXIC EFFECTS OF ASTROKS AND MEXIDOL IN INJECTABLE FORM AND 2-ETHYL-6-METHYL-3-HYDROXYPYRIDINE SUCCINATE SUBSTANCE

The purpose of this study was to examine in experiment anticonvulsant and antihypoxic action of 2-ethyl-6-methyl-3-hydroxypyridine succinate medications — Astroks in injectable form (vial of 100 mg in 2 ml) compared with Mexidol injectable form (vial of 100 mg in 2 ml) and the substance 2-ethyl-6- methyl-3-hydroxypyridine succinate (EMHPS). Materials and methods. Simulation of primary generalized eizures was performed using the maximal electroshock (MES) and pentylenetetrazole injection. Antihypoxic effects of drugs was studied on the model of normobaric hypoxia with hypercapnia.Results: it was found that astroks injection at a dose of 200 mg/kg has a similar antihypoxic and anticonvulsant efficacy with EMHPS substance. Compared to injectable form of Meksidol astroks has similar efficacy in the test of antagonism with MES. Astroks exceeds the effect of Mexidol in the test of antagonism with pentylenetetrazole and has more severe antihypoxic action.Conclusion. Аstroks injectable has pronounced antihypoxic and anticonvulsant action in the experiment which have some advantages over injectable Meksidol

ELECTROPHYSIOLOGICAL MECHANISMS OF ANTIEPILEPTIC ACTIONS REALIZATION OF BEPRODON

The purpose of this research was to study electric and physiological mechanisms of the achievement of the antoconvulsant effect of the new original beprodon combination together with determination of determinant brain structures – therapeutic targets.Materials and Methods. Partial (focal) and secondary generalized convulsions were generated using the method of creation of a chronic epileptogenic focus, caused by the cobalt application on rats’ brain.Results: it was revealed, that at the first stage of the epileptic system (ES) beprodone is targeted to cortical focuses, and at the second stage – to subcortical focuses, generating epileptic activities. Conclusion: the beprodone effect depends on the stage of the epileptic system development and is targeted to determinant focuses
