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.

The paper deals with study by the method of solid-phase indirect immunoenzyme analysis of levels of the novel serotonin-modulated anticonsolidation protein (SMAP) that is directly correlated with serotonin level as well as of biomarker cytochrome P-450 in the liver, gills, and brain of the eastern alburnoid (Alburnoides bipunctatus eichwaldi) caught in the rivers Khudat, Akstafachai, Kura, and Araks flowing at the territory of Azerbaijan. There was revealed a marked downregulation of cytochrome P-450 and SMAP in the liver and gills of the fish caught in the Akstafachai River relatively to values in the fish from the Khudat River not contaminated with pollutants. In the liver and gills in the fish from the Kura and Araks rivers, a significant differently directed changes of the cytochrome P-450 and SMAP levels were observed: downregulations of the cytochrome P-450 versus an upregulation of SMAP.

Using indirect solid-phase ELISA-test, the serotoninergic system activity was evaluated by measuring in the tissues of the studied fish the serotonin-modulated anticonsolidation protein (SMAP) which is in linear relationship with serotonin level.

The experiment was performed in three stages: (1) fry of carps Cyprinus carpio L. was injected intracerebrovenricularly with the SMAP protein at a dose of 0.

Two series of experiments were carried out in Wistar male rats. In the first series, rats were trained to acquire conditioning in a shuttle box to 50% and 80% learning criteria. In the animals of the experimental group that achieved 50% learning criterion, a significant decrease in the levels of serotonin-modulated anticonsolidation protein (SMAP) (solid phase, indirect ELISA-test) was observed in the temporal cortex as compared to the animals of the active control group.

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.
