Influence of Implants Surface Properties on Bone Tissue Formation in the Ectopic Osteogenesis Test.

We studied the influence of the characteristics of oxide porous coatings on osteogenesis and integration of new bone tissue and titanium implant surface in the ectopic osteogenesis test. Implants with coating with pore size 2-20 μ exhibit better osteogenic and osteoconductive characteristics than implants with homogenous surface and smooth relief (pore size 0.5-5.

[Multiplicity of B microchromosomes in a Siberian population of mice Apodemus peninsulae (2n = 48 + 4-30 B chromosomes)].

Differentiation of four Siberian populations of East-Asian (Korean) field mice (Apodemus peninsulae) inhabiting the basin of the mid-stream of the Yenisei River was carried out according to the variants of the B chromosome system. A multiplicity of B microchromosomes (from 4 to 30) was found for the first time in all 26 mice from the left shore of the Yenisei River in the mid-stream area. All of them probably belong to a population with B microchromosomes.

[The complicated intestinal amebiasis in emergency surgery].

18 patients with complicated forms of intestinal amebiasis were operated on acute appendicitis, liver abscess or total necrotic colitis. Appendectomy, abscess drainage and colon resection were performed respectively. There were no postoperative deaths.

[Bacterial translocation under the conditions of acute bowel obstruction].

The article is dedicated to bacterial translocation under the conditions of acute small and large bowel obstruction, studied in experiment using bacteriological methods. The degree of contamination of internal organs, blood, and peritoneal exudate in the dynamics of the pathological process was determined. The study found that the use of allopurinol, a xanthine oxidase inhibitor, reduced the intensity of bacterial translocation.

[Diagnosis and treatment of complicated postnecrotic cysts of pancreas].

Experience of complex treatment of 137 patients with complicated postnecrotic pancreatic cysts (PPC) is analyzed. Indications to different surgical methods are formulated differentially depending on complications of cysts, localization, sizes, "maturity" of cyst walls, communication with main pancreatic duct. Treatment of festered PPC should be started with minimally-invasive methods; at negative result the omentobursocystostomy with staged endoscopic sanations should be done that permits to decrease the number of postoperative complications and to reduce lethality from 14.
