[The cytochemical indicators in patients with II stage hypertension disease and isolated traumas of long tubular bones of lower extremities].

The cytochemical indicators of neutrophils of peripheral blood were analyzed in 30 patients with hypertension disease and isolated traumas of long tubular bones of lower extremities. It is established that in such patients the variations of microbicidal neutrophils systems manifest in the increase of content of cationic proteins and non-significant decrease of myeloperoxidase activity. This is one of mechanisms of immunity support during first 48 hours after trauma.

Poly(2-hydroxyethyl methacrylate) emboli with increased haemostatic effect for correction of haemorrhage of complex origin in endovascular surgery of children.

Poly(2-hydroxyethyl methacrylate) (PHEMA) embolization particles with enhanced haemostatic properties were prepared by bulk or suspension polymerisation of 2-hydroxyethyl methacrylate (HEMA) followed by particle soaking in ethamsylate solution. The particles accelerated thrombus formation as evidenced by blood analysis of rabbits with implanted emboli. Usefulness of both spherical and cylindrical PHEMA particles with enhanced haemostatic effect was demonstrated on the embolization of arterial anastomosis, fistulas of the lower extremity and abdominal cavity, haemangioma and arteriovenous malformation of the head of several children.

Poly(2-hydroxyethyl methacrylate) microspheres/liquid poly(dimethylsiloxane) composition for correction of small defects in face: histological evaluation in animal experiment.

Two kinds of composition based on commercial liquid poly(dimethylsiloxane) and laboratory-made poly(2-hydroxyethyl methacrylate) (PHEMA) microspheres of different size fractions (30-40 or 125-180 microm) were prepared. Tissue reaction on injection of the compositions, optimum microsphere size and morphology were investigated in the experiments on rats. The microspheres induced foreign body reaction characterized by an increased content of fibroblasts and mild infiltration of injection field by inflammatory cells.

[A comparative study of changes in suture materials in mammary gland tissues].

In the experiment on 75 white rats, the reactogenicity and strength of catgut, dexon, kacelon and PGL (native analogue of vicryl) were studied 10, 20 and 30 days after their implantation into parenchyma of the lactating mammary gland (MG). Around a catgut thread, the cellular-tissue reaction according to the type of purulent inflammation occurred. A danger of oncogenic effect of catgut which manifested itself in proliferation and atypical hyperplasia of epithelium of the MG ducts was noted.

[The system of designation of surgical suture materials].

The authors suggest a unified system of designation of type--sizes of surgical suture materials of various nature and structure, which removes the existing discrepancy between the numbering of foreign and Soviet threads as well as of Soviet threads produced by different enterprises of the country. Introduction of the new system of metric sizes of the suture threads will allow surgeons to be properly orientated in the choice of the necessary suture material and make easier the work of services engaged in the development and realization of surgical suture materials.
