[Fracture healing under intramedullary insertion of wires with hydroxyapatite coating].

Aim: To study morphological features of the bone formation process in consolidation of fractures of long tubular bones in conditions of intramedullary wires insertion with bioactive calcium-phosphate coating of hydroxyapatite.

Materials And Methods: In experimental study in dogs was simulated open comminuted tibia fracture and performed intramedullary insertion of wires with hydroxyapatite coating. Using light and electron microscopy, using X-ray electron microprobe microanalyses were studied bone regenerates in 14-360 days after surgery.

[Cardiac angiosarcoma in a pregnant women].

We present a case of cardiac angiosarcoma in a pregnant women. Clinical manifestations of angiosarcoma were unspecific and progressed rapidly as hemopericardium, cardiac tamponade, heart failure, fever, chest pain. Pregnancy was interrupted at 22-nd week.

[The electrophoretic cell analysis applying the instrument complex "Cito-expert"].

The electric discharge of living cells and Z-potential of cell membrane are among the most important indicators to determine at cell level the homeostasis of any living organism, including organs and tissues. The cell electrophoresis is considered as the most handy, accurate and reliable practical technique to determine these indicators. The authors developed the first national serial instrument complex for cell electrophoresis.

[Cardiac angiosarcoma].

The paper outlines the authors'case of cardiac angiosarcoma. It provides the gross and microscopic characteristics of this tumor and procedures for its clinical and immunomorphological diagnosis.

[Immunophenotype of neoplastic cells and its clinical significance in chronic lymphocytic leukemia].

y We report preliminary results of efficacious clinical application of a new immunological method with the use of biochips for diagnosis of chronic lymphocytic leukemia. This method has been developed by the authors to detect a wide range of cell surface antigens. We compared the amount of cells expressing certain antigens with clinical properties of chronic lymphocytic leukemia.

[Dynamics of destructive and reparative processes in organs of the immune system in acute experimental peritonitis of varying course].

A quantitative characteristics of destructive and reparative processes in the organs of immune system is given on the model of acute peritonitis running under different conditions. During the usual course of inflammation in the abdominal cavity in the first 24 hours a sharp increase of lymphocyte destruction is noted, while proliferative changes decrease. Two days later the cell destruction decreases but proliferative changes increase.

[Cystinosis in an adult].

The paper reports a case of cystinosis with the involvement of kidneys, myocardium and liver in a female of 43. Late development of kidney failure might be due to a partial deficiency of the enzyme responsible for a cystine transport in the cell.

[Anti-reflux biliary-digestive anastomosis including the gallbladder in the light of long-term results].

The authors provide the long-term results of cholecysto-digestive + anastomoses in 59 patients operated on for nontumorous diseases. The gallbladder anastomosed with the upper parts of the alimentary tract preserved reservoir and concentration functions, ability for visualization during cholecystocholangiography. The discrete pulse mechanism of bile secretion via the bile diverting anastomoses and their antireflux function eliminated the risk of chronic pancreatitis and terminal cholangitis.

[Mortality in acute peritonitis as revealed by postmortem examination findings].

Acute peritonitis has been found present on 512 out of 4303 serial postmortem examinations performed over the past 10 years in the city of Izhevsk, giving the overall rate of 11.9%, but the rates were higher in older age groups. The conditions more commonly complicated by peritonitis were inflammatory and neoplastic diseases of abdominal organs.

[Origin of the tumor cells in lymphogranulomatosis].

Tumor cells in lymphogranulomatosis include Hodgkin's cells, Berezovsky-Shternberg cells and variants thereof representing a single population characterized by aneuploidy, polyploidy, and marker chromosomes. All cells of this clone are capable of DNA synthesis and mitotic division. As the disease progresses, the number of tumor cells increases gradually.
