Dynamic observation of X-ray Laue diffraction on single-crystal tungsten during pulsed heat load.

The dynamics of the diffraction peak shape during pulsed heat load on mosaic single-crystal tungsten were measured at the `Plasma' scattering station on the eighth beamline of the VEPP-4 synchrotron radiation source at the Budker Institute of Nuclear Physics. The observed evolution of the diffraction peak shape agrees with theoretical predictions based on calculations of deformation caused by pulsed heating. Three clearly distinguishable stages of the diffraction-peak evolution were found, correlating with the evolution of temperature and deformation distributions.

[Optimization of hepatoprotective therapy of viral hepatitis with consideration of neuromediatory link of pathogenesis].

Aim: To study therapeutic efficacy of hepatoprotective modalities on the experimental hepatitis model and in patients with parenteral hepatitis B and C regarding neurogenic amines and their coefficients.

Material And Methods: 38 hepatoprotectors were screened for the highest activity in 1000 white rats with toxic hepatitis. Blood catecholamines (CA), histamine (H), serotonin (S), 11-oxycorticosteroids (11-OCS) were studied in 100 patients with acute hepatitis B and C.
