[First experience of laparoscopic appendectomy in the 150-bed garrison hospital].

The article reflects the results of the first laparoscopic appendectomy experiment which was conducted on the base of 30 person department of the military hospital for 150 patients. The researcher made the statistical analysis of the results of acute appendicitis diagnostic and cure among young men. For the group of patients whit catarrhal form of acute appendicitis separate analysis was committed.

[Increase of mutation level in tissues of goby and fry of sturgeon under conditions of block by antibodies against serotonin-modulated anticonsolidation protein].

The work present data on studies of a decreased activity of serotoninergic system on the level of mutagenic changes (the micronuclear test) in the goby Neogobius fluviatilis and the fry if sturgeon Acipenser güldenstädti persicus. It has been shown that the long exposure of the animals to conditions of industrial and oil pollution leads to a significant decrease in their liver of the level of serotonin-modulated anticonsolidation protein (SMAP) correlating directly with the serotonin level as well as to sharp increase of the level of micronuclei in erythrocytes. The intramuscular administration of anti-SMAP polyclonal antibodies to the fry of the sturgeon produces a significant increase of the amount of micronuclei as compared with that in the animals injected with non-immune gamma-globulin.

[Participation of serotonin-modulated anticonsolidation protein in mediation of action of adverse factors on lipid peroxidation level in juvenile sturgeon tissues Acipenser güldenstädti persicus].

The work analyzes participation of the serotoninergic system in correction of adverse effects of benthic deposits contaminated with industrial wastes on the level of lipid peroxidation (LPO) in the fry of the sturgeon Acipenser güldenstädti persicus. In the first series of the study, two intramuscular injections to the fry of the sturgeon of serotonin-modulated anticonsolidation protein (SMAP) that is in the direct correlation with the serotonin level led to pronounced normalization in the animal tissues of the LPO level whose increase was due to keeping the sturgeons in the fresh water contaminated with benthic deposits. In the second series of the study, administration to the animals of polyclonal anti-SMAP antibodies led to a significant increase of the LPO level in the tissues, similar to effects of the benthic deposits.

Decrease in activity of the serotoninergic system during mutagenesis.

We studied changes in the content of serotonin-modulated anticonsolidation protein in the liver of goldfishes and gobies caused by oil and industrial pollution. The concentration of serotonin-modulated anticonsolidation protein in fish liver increased after short-term exposure to oil-contaminated water (100 mg/liter), but decreased under long-term effect of industrial wastes. We hypothesize that serotonin plays a role in antimutagenic protection of the organism and maintains the differentiated state of mature cells.

[Outer nuclei of the diencephalon pretectal area of the sturgeons].

Cytoarchitectonics of outer nuclei of the pretectal area was studied in four species of the sturgeons: the great sturgeon Huso huso, L., the Russian sturgeon Acipenser güldenstädti persicus n. kurensis, Belyaeff, the starred sturgeon Ac.
