Flexner's dysentery is often accompanied with intestinal dysbacteriosis. Disbiotic changes in the intestine contribute to specific shigella endotoxins entering blood flow thus prolonging clinical symptoms of the underlying disease. Administration of bacterial biological preparations (bifidumbacterin forte, lactobacterin) relieves specific endotoxemia, reduces the duration of the disease and has an immunomodulating action. 相似文献

A comparative effect of the preliminary treatment of lamellar silicate with sulfuric and orthophosphoric acids on the subsequent
phenol sorption is carried out. Mechanisms of the phenol adsorption on specimens treated with different acid solutions are
found to be different. It is shown that orthophosphoric acid is preferable as an activator of montmorillonite, which can then
be used in biochemical decontamination of the sewage of by-product coke industry.

We studied the high-pressure effects on the crystalline structure of monoclinic HfTiO4 and ZrTiO4. We found that the compressibility of these ceramics is highly non-isotropic, being the b-axis the most compressible one. In addition, the a-axis is found to have a small and negative compressibility. At 2.7 GPa (10.7 GPa) we discovered the onset of a structural phase transition in HfTiO4 (ZrTiO4), coexisting the low- and high-pressure phases in a broad pressure range. The new high-pressure phase has a monoclinic structure which involves an increase in the Ti-O coordination and a collapse of the cell volume. The equation of state for the low-pressure phase is also determined. 相似文献

Conclusions It has been shown that nitromethane can be used successfully for separating kerosene-gas oil fractions to obtain raffinates which satisfy the requirements for diesel fuel plus highly aromatized extracts which contain less than 6% of saturated hydrocarbons.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 8, pp. 27–29, August, 1967. 相似文献

The influence of chromium and silicon on the structure of the diamond–WC–6Co composite doped by chromium disilicide has been studied at the meso-, micro-, and submicron levels. It is established that under the conditions of the structure formation of the diamond–WC–Co + CrSi2 chromium and silicon do not dissolve in particles of diamond and WC carbide, they form a Co(W,C,Cr,Si) solid solution decreasing the energy of the stacking fault, which contributes to the Co(fcc) → Co(hcp) polymorphic transformation. Chromium interacts with atoms of carbon in diamond and WC carbide, as a result of which the graphite layer in the diamond/Co phase contact zone disappears and the Co3W3C carbide forms in the volume of the WC–Co-matrix. Chromium and silicon contribute to a good retention of diamond particles by the WC–Co-matrix and increase the ultimate strength in compression of the diamond–WC–Co+CrSi2 composite. 相似文献
