[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.
