[Hepatolithiasis].

The authors present an analysis of treatment results in 14 patients with hepatolithiasis. An influence of chronic opisthorchosis invasion on the frequency was determined. Hepatolithiasis was detected in 8 (0.

[Internal biliary fistulas as a complication of cholelithiasis].

The authors made an analysis of observations of 46 patients. They describe algorithm and problems of clinico-instrumental and X-ray diagnostics, strategy of operative treatment and postoperative complications.

[Formation of paramagnetic nitrosyl complexes of non heme iron in animals with participation of nitric oxide from exogenous and endogenous sources].

It was found that thiosulfate has a stabilizing effect on exogenous and endogenous dinitrosyl-iron complexes in mice treated with bacterial lipopolysaccharide. It was assumed that thiosulfate protects dinitrosyl-iron complexes from the destructive influence of superoxide and peroxinitrite whose enhanced synthesis, together with the synthesis of nitric oxide, is initiated in mice by the lipopolysaccharide. For the first time, the formation of dinitrosyl-iron complexes was demonstrated, which occurs with the participation of nitric oxide generated enzymatically via the L-arginine-dependent pathway.

[Pericholedochal lymphadenitis in complicated opisthorchiasis].

The data on frequency, location and pronouncement of pericholedochal lymphadenitis in complicated forms of chronic opisthorchiasis requiring surgical correction have been summarized. Pericholedochal lymphadenitis is caused by infection in the bile ducts which is the most frequently noted in cholestasis. The authors recommend to perform external drainage of the bile ducts with the aim of their sanation.

[A rare case of infiltrative growth of alveococcus in the aorta and its branches].

Widespread liver alveococcosis resulted in the infiltrative growth into the celiac and superior mesenteric arteries with their complete obturation with the parasitic tissue, but without the disturbance of circulation in the digestive organs. This was due to slow obliteration and the development of collateral circulation.

[Opisthorchiasis of the liver].

The authors have observed 10 patients with opisthorchiasic cysts of the liver. These cysts are multiple and disposed mainly in the left lobe of the liver. Sonography and laparotomy are expedient methods for diagnosis of the disease.

[Comparative characteristics of nonparasitic and opisthorchiasis cysts of the liver].

The authors observed 24 patients with opisthorchiasis and 14--with nonparasitic cysts of the liver. No essential differences in the tactics of surgical treatment of these cysts were noted. In medium-size and large cysts, the operative treatment--excision of cystic walls with omentoplasty, liver resection--is recommended; in small opisthorchiasis and nonparasitic cysts--dynamic observation with the performance of ultrasound scanning.

[Opisthorchiasis-induced suppurative cholangitis (clinical course and diagnosis)].

Purulent cholangitis was found in 128 (44.6 per cent) of the 288 patients operated on for complicated forms of opisthorchiasis. Mechanical cholestasis due to sclerotic changes in the bile ducts, major duodenal papilla and pancreas is the most responsible factor in disease prognosis.

[Effect of immunosorption on the functional state of immunocompetent cells].

The effect of immunosorption on the state of the membranes of immunocompetent cells playing an important role in numerous links of pathogenesis of disease was studied in 11 patients with bronchial asthma (atopic form). Two biophysical methods were employed: a fluorescent probe (a chlorotetracycline probe) and hemiluminiscence. A preliminary study showed noticeable changes in the state of cell membranes in patients with atopic bronchial asthma and aggravation of pathological changes caused by a specific allergen.
