[Morphological characteristic of tissues, surrounding prosthesis in patients, suffering cutaneo-prosthetic fistulas and paraprosthetic hernias].

While application of the net prostheses in surgery of anterior abdominal wall hernias (AAWH) the complications are noted, such as the prosthesis cyst development, the net wrinkling, migration and separation with the hernia recurrence. Morphological investigation of tissues were conducted in regions of cutaneo-prosthetic fistulas and hernial gates, formatted by the prosthesis edge, in 22 patients, operated for AAWH, in 6 of them cutaneo-prosthetic fistulas were observed. Morphological changes in region of prosthesis, taking part in the hernial defect development, as well as in the wrinkled part of the prosthesis, were characterized by pronounced inflammation, development of rude cicatrices and infiltration of tissues.

[Scanning electron microscopy of resected ureters in children with ureterohydronephrosis].

Using scanning electron microscopy, various portions of the ureter in reflux and obstructive ureterohydronephrosis in children were evaluated. In the first case, architectonics of the distal portions is preserved, while in the second case connective tissue is proliferated. Differences in the structure of proximal and distal portions in both forms of ureterohydronephrosis consist in inflammatory changes and violation of the integrity of the epithelial lining, edema and infiltration of the underlying layers, especially the inner muscle layer of the distal portion.

[Possibility of the liver ultrastructure recovery in intoxication with heavy metals salts].

Experimental studies helped to reveal ultrastructural changes in hepatocytes, caused by prolonged exposure to heavy metals salts taken in combination and ratios characteristic to soil contents near Almalyk mining and smelting enterprise. The authors demonstrated possibility of liver structural recovery via enterosorption with additional antioxidant therapy.

Effect of laser irradiation of donor blood on erythrocyte shape.

Changes in erythrocyte shape in donor blood during storage and after irradiation with He-Ne laser and infrared laser were studied by scanning electron microscopy, thick drop express-method, and morphometry. It was found that laser irradiation delayed the appearance of erythrocytes of pathological shapes (echinocytes, stomatocytes, etc.) in the blood; He-Ne laser produced a more pronounced effect.

[Surgical treatment of septicopyemic form of acute hematogenous osteomyelitis in children].

The results of treatment of 175 children with a septicopyemic form of acute hematogenous osteomyelitis were analyzed. A method of surgical treatment using an original device for osteopuncture and intraosseous infusions was introduced in the clinic with regard to the results of studying morphological features of changes in the contents of the intramedullary canal. This surgical strategy allowed shortening the period of hospital treatment, reduction of the number of complications and avoidance of lethal outcomes of children with the septicopyemic form of the disease.
