[Genome damage and reactive oxygen species production in the progenies of irradiated CHO-K1 cells].

A series of experiments to study the delayed effects of gamma-radiation exposure in different generations of the progenies of the Chinese hamster ovary CHO-K1 irradiated cells has been conducted. It has been shown that in the progenies of the cells irradiated with a dose of 1 Gy, the following effects are observed: in the 9-27 cell generations - increase in the genome damage, intracellular production of reactive oxygen species, apoptotic cells percentage and cell sensitivity to additional exposure (irradiation at a dose of 10 Gy); in the 30-42 cell generations - decrease of the studied parameters up to control values and increased resistance to additional exposure. It is assumed that the decrease of the studied parameters up to the control values in the 30-42 postirradiation generations of cells is caused by elimination of damaged cells or transition of genomic instability into a hidden (latent) condition.

[The radiationally induced change of level of double-stranded breaks DNA in neuroblasts of larvae and frequency of lethal mutations in sex cells of males Drosophila melanogaster].

The level of damage DNA in neyroblastes of larvae and frequency of recessive sex-linked lethal mutations of males from chronically irradiated populations Drosophila melanogaster, differing on mobile P-elements patterns, was estimated. Received results testify, that exposition in conditions a chronic gamma-radiation (absorbed radiation dose at one generation is compounds 10 mGy) result to increase of significance of parameters and change of sensitivity of cells to following of an acute irradiation in a dose of 3 Gy.

[Modern approaches to the therapy of biliary system diseases].

The therapeutic efficacy of duspatalin was evaluated in 72 patients with chronic cholecystitis and dyskinesia of the biliary tract (BT). Supplementation of duspatalin to the combined therapy in the patients with chronic cholecystitis shown to exert a pronounced therapeutic effect. This caused positive changes in clinical symptoms and BT function and quality of life, diminished the lithogenic properties of bile.

[The effectiveness of spasmolytic therapy in chronic acalculous cholecystitis].

The therapeutic efficacy of duspatalin was evaluated in 69 patients with chronic cholecystitis and dyskinesia of the biliary tract (BT). Supplementation of duspatalin to the combined therapy in the patients with chronic cholecystitis shown to exert a pronounced therapeutic effect. This caused positive changes in clinical symptoms and BT function and quality of life, diminished the lithogenic properties of bile.

[Histomorphological study of mice inbred CBA liver under combined chronic influence of low dose gamma radiation and incorporated thorium nitrate].

We studied histomorphology of the CBA line mice liver after 30 and 90 days of the low dose gamma-radiation influence combined with incorporated Th(NO3)4 in doses 0.03; 0.1; 0.
