[Efficacy and perspective of application of preparation based on hydrogel and xerogel of methyl-silicic acid in patients with the intestinal malignancy].

There was studied the influence of medicinal preparations, created on the base of methylsiliconorganic matrix, on immediate and late follow-up result of treatment of more than 2000 patients with the digestive channel malignancy. High efficacy of application in complex of preoperative preparation of immobilized antibiotics and cytostatics, enterosorpent enterosgel for the purulent-inflammatory complications prophylaxis, lowering of bilirubin level in tumoral obturative jaundice, and in intraoperative usage for the tumor and metastases recurrences prophylaxis.

[Na and Mg K-edge XANES study in silicate glasses].

The structural role of Na in Na2-O-SiO2 and Na2O-SiO2-P2O5 glasses was studied using Na K-edge XANES (X-ray near edge structure) spectra. The Na K-edge XANES shows little change with increase in the content of Na2O in Na2O-SiO2 glasses. However, the addition of P into the Na2O-SiO2 system causes dramatic change of the Na K-edge XANES, and the Na K-edge spectra of Na2O-SiO2-P2O5 glasses also change with the increase of P2O5 content. The structural role of Mg in CaMgSi2O6 (Di)--NaAlSi3O8 (Ab) glasses was studied using Mg K-edge XANES spectra. The Mg-O bond distance in these glasses is estimated to be 2.00 +/- 0.04 A. Thus, Mg in these glasses may be five coordinated with oxygen, or Mg may have multiple structural sites, MgIV, MgV and MgVI. The Di-Ab glasses may possess a medium-range ordering structure.
