Aggressive social environment and stress still remain urgent problems of neurochemistry. Psycho-emotional disorders, which took place in Georgia in 90ies of the last century due to the darkness, caused by the lack of electricity, total absence of heating in premises and social isolation, caused increase in the incidence of murder and suicide. Considering this our aim was to study changes in distribution of biogenic amines while placing rats in the dark (1/23), cold environment and isolation. It has been established that maintenance of rats under such conditions has caused 50-70% decrease in concentration of serotonin in the midbrain, hypothalamus and hippocampus. Serotonin was admitted as a correlate of aggression. Because of the recent increase of suicide cases among teenagers, we’ve studied effect of sexual hormones on formation of aggressive organism, as particularly at this age significant shifts take place in quantitative distribution of hormones. With this intention rats were castrated and tested on aggression/murder towards mice and frogs. After being castrated rats became tolerant to them. Not a single case of murder was registered, though injection of male sexual hormone testosterone again evoked aggression towards mice and frogs and entailed cases of murder. Rats were exhausted by swimming in water basin with the aim of prevention of aggression and then their behaviour was observed. Tired rats again revealed tolerance to mice and frogs and cases of murder were not fixed. Considering the above we can conclude that during intervals between lessons in schools teenagers should necessarily be loaded with increased physical activities. This will allow to avoid irritating effects of pheromones and sexual hormones in teenagers. The method was developed using lectins, which allows identification of aggressive organisms and their further cure.
