[An analysis of forensic medical expertise on matters of the professional law infringements of medical workers].

Expert evaluation of the correctness of medical care is one of the most complex problems for experts. A total of 303 expert evaluations of this kind were carried out in the Moscow regional Bureau during the recent 11 years. Expert evaluation of surgical care were the most numerous.

[The effect of conditions of storage and composition of viral material on lipid peroxidation of the viral envelope and inactivation of the influenza virus].

Lipid peroxidation (LPO) develops in the virus envelopes in the course of storage of influenza virus suspensions. It is registered by fluorescent methods by the time course of intermediate products (short-chain dialdehydes) and final products of LPO (fluorescent pigment), this being characteristic of an autocatalytic process. The conformity of the basic regularities of LPO and virus inactivation in samples differing by the storage conditions, concentrations of virions and antioxidants (alpha-tocopherol acetate and phenosan) permits us to consider LPO as an important mechanism of enveloped virus inactivation during storage.

[The separation of subunits of phenylalanyl-tRNA-synthetase from Escherichia coli MRE-600 by means of affinity chromatography in dissociation conditions].

The method of affinity chromatography on sepharose with immobilized tRNA in the presence of urea was developed for separating the subunits of phenylalanyl-tRNA synthetase from E. coli MRE-600 (subunit structure alpha 2 beta 2). Specific binding of large beta-subunits of the enzyme on immobilized tRNA testifies the localization of the tRNA-binding center on the beta-subunit of phenylalanyl-tRNA synthetase.
