[Induction of gene and deletion mutations by accelerated heavy charged particles in Escherichia coli cells].

The results of the induction of the point and the deletion mutations by the radiation with broad region of linear energy transfer (LET) ox Escherichia coli cells. The linear-quadratic function for point mutation induction was shown in comparison with linear dependence for deletion mutations. The relative biological effectiveness (RBE) is described as a function of LET by dependence with a local maximum.

[Treatment of suppurative-necrotic wounds of the extremities].

The article discusses the authors' experience in treating pyonecrotic and poorly granulating wounds of the upper and lower extremities in 158 patients; proteolytic enzymes, application of carbohydrate sorbents, and helium-neon laser radiation were used in 66 cases. With such method of treatment, the wounds healed without cutaneoplasty in 75% of cases. In 25% of cases free cutaneoplasty was performed after preparation of the wound surface.

[Sorption detoxication in the treatment of open fractures of the extremities complicated by purulent infection].

The article describes the authors' experience with the treatment of open diaphyseal and intra-articular fractures of bones of the upper and lower extremities complicated by purulent infection, in 126 patients sorption methods being used (hemosorption, enterosorption, application of sorbents on the wounds). Results of the treatment were studied in 120 patients within the period from 1 year to 6 years. Good results were obtained in 44 patients (36.
