CONTEMPORARY PROBLEMS OF ABDOMANAL DELIVERY

The review examined Cesarean section significance in decrease of perinatal mortality, the problems associated with the increase of abdominal delivery are reflected, purulent-septic complications are accented, risk factors of infection-inflammatory process development in post operational period are analysed, the advantages and disadvantages of contemporary preventive methods of their origin are considered

THE ANALYSIS OF RISK FACTORS OF PURULENT-SEPTIC COMPLICATIONS DEVELOPMENT AFTER ABDOMINAL DELIVERY

Purpose: estimation of risk factors and degree of their significance in infectious-inflammatory processes development after Cesarean section.Materials and methods: the retrospective medical documentation analysis of 2235 cases of operative delivery.Results: it is established that antibiotic prophylaxis at a Cesarean section during the investigated period was carried out without contemporary risk factors, an individual estimation of qualitative-quantitative structure genital tract microflora and its account antibiotic -sensitivity in 16.2 % of cases led to nonspecific inflammatory complications development in the postnatal period. Contemporary risk factors of inflammatory complications development in abdominal delivery are revealed.Summary: it is necessary to accomplish a working out and introduction of contemporary and scientifically proved algorithm of purulent-septic complications prevention after abdominal delivery in work of obstetric permanent establishment, taking into account modern risk factors

The Soviet-American gallium experiment at Baksan

A gallium solar neutrino detector is sensitive to the full range of the solar neutrino spectrum, including the low-energy neutrinos from the fundamental proton-proton fusion reaction. If neutrino oscillations in the solar interior are responsible for the suppressed {sup 8}B flux measured by the Homestake {sup 37}Cl experiment and the Kamiokande water Cherenkov detector, then a comparison of the gallium, chlorine, and water results may make possible a determination of the neutrino mass difference and mixing angle. A 30-ton gallium detector is currently operating in the Baksan laboratory in the Soviet Union, with a ratio of expected solar signal to measured background (during the first one to two {sup 71}Ge half lives) of approximately one. 28 refs

Photoluminescence properties of self-assembled chitosan-based composites containing semiconductor nanocrystals

The photoluminescence (PL) properties of composites obtained by embedding green-emitting semiconductor nanocrystals (NCs) of two different types (thiol-capped CdTe and CdSe/ZnS) into chitosan-based biopolymer particles were investigated. The synthesis of self-assembled particles from oppositely charged polysaccharides involved a preliminary electrostatic binding of positively charged chitosan chains by negatively charged functional groups of NC stabilizing ligands. The amount of NCs and the acidity of the solution were found to be important parameters influencing the PL. The PL properties were mainly discussed in terms of the colloidal stability of the particles and changes in energy gap of NCs. Generally, the obtained biocompatible composites with NCs randomly distributed within a biopolymer particle demonstrated a higher PL resistance to the solution acidity that expands the applicability range of thiol-capped NCs
