[Anthropogenic environmental factors and their role in the occurrence of acute respiratory diseases]. / Antropogennye faktory okruzhaiushchei sredy i ikh rol' v razvitii ostrykh respiratornykh zabolevanii.

The incidence of acute respiratory diseases (ARD) in two districts of the Orenburg Region which have different levels of environmental pollution was comparatively analyzed. The higher incidence of ARD in the more polluted district (Kuvandyksky) than in the control one (Belyaevsky). The incidence rate (41.8%) of ARD correlated with the level of the ambient air pollution by dust, CO, NO2, NF and fluoride aerosols in the Kuvandyksky district.

[Use of polypropylene single thread as the suture material]. / Primenenie polipropilenovoi mononiti v kachestve shovnogo materiala.

The authors studied the results of using polypropylene monothread as suture material in 254 patients who underwent planned and emergency operations for various diseases. It was found that polypropylene monothread used for suturing the skin, deeper located tissues, granulating wounds is sufficiently elastic, acapillary, strong, and biologically inert owing to which there is no need to remove it until complete healing of the wound even in considerable exposition. The monothread causes a less traumatizing effect than does a thread of natural silk when drawn through the tissues. A blue or green color of the monothread makes it visible during the operation.

[Experience with and the prospects of using a single polypropylene thread in surgery of suppurative wounds]. / Opyt i perspektivy primeneniia polipropilenovoi mononiti v gnoinoi khirurgii.

A polypropylene monofilament in placing secondary sutures causes minimal damages in the tissues. The absence in a monofilament of the capillary-filtrative properties prevents the development of infiltrate, suppuration, dehiscence of the wound edges. In using a modified suture of the granulating wound, suggested by the authors, a good cosmetic and functional effect was noted.

[Immobilization of peroxidase from the culture filtrate of the basidial fungus Cerrena maxima Murr]. / Immobilizatsiia peroksidazy iz kul'tural'nogo fil'trata bazidiol'nogo griba Cerrena maxima Murr.

Immobilization of peroxidase produced by the basidial fungus Cerrena maxima Murr on the alginate fiber was investigated. The mode of enzyme immobilization directly from the filtrate of the fungal culture fluid was established. Electrophoretic examination of peroxidase protein components and isoenzymes showed that immobilization of the fungal peroxidase on the alginate fiber was followed by sorption of primarily protein components responsible for the peroxidase activity.
