[Comparison of a medical effect of cryosupernatant and fresh frozen plasma used in complex treatment of patients with severe combined traumas].

Results of complex treatment of severe combined traumas were compared in 56 patients with using cryosupernatant plasma fraction (CSPF) and fresh frozen plasma--in 112 patients. Better positive dynamics of some laboratory indices was noted as well as lower risk of the development of thromboses, less lethality and better outcomes of the disease when using CSPF. It can be used instead of fresh frozen plasma in complex treatment of patients with severe combined traumas and coexisting DBC-syndrome.

Heat capacity and thermal expansion of the itinerant helimagnet MnSi.

The heat capacity and thermal expansion of a high quality single crystal of MnSi were measured at ambient pressure at zero and high magnetic fields. The calculated magnetic entropy change in the temperature range 0-30 K is less than 0.1R, a low value that emphasizes the itinerant nature of magnetism in MnSi. A linear temperature term dominates the thermal expansion coefficient in the range 30-150 K, which correlates with an enhancement of the linear electronic term in the heat capacity. A surprising similarity among the variations of the heat capacity, thermal expansion coefficient and temperature derivative of the resistivity is observed through the phase transition in MnSi. Specific forms of the heat capacity, thermal expansion coefficient and temperature derivative of resistivity at the phase transition to a helical magnetic state near 29 K are interpreted as the combination of sharp first-order features and broad peaks or shallow valleys of as yet unknown origin. The appearance of these broad satellites probably hints at a frustrated magnetic state slightly above the transition temperature in MnSi.

[Resorption from the pericardial cavity during growth in normal conditions and in experimental pericarditis]. / Osobennosti rezorbtsii iz perikardial'noi polosti rastushchego organizma v norme i pri éksperimental'nom perikardite.

The isotope 131I-hippuran was introduced via a microirrigator into the pericardial cavity of 26 puppies aged 1--3 months to study resorption function of the epicardium. Pericarditis was induced by administering the culture of Staph. aureus into the cavity. It was disclosed that in health the isotope half-life falls within the 12th minute, while complete elimination within the 45th--50th minute. On the 5th--6th day of experimental pericarditis, the resorption becomes 6 times slower, on the 14th day it returns to normal and on the 28th day exceeds normal 3--4 times. This fact is a consequence of a powerful development of the subepicardial venous network.
