title: [Characteristic reaction of early sea urchin embryos to cytostatic analogs of transmitter substances].
abstract: Early embryos of Arbacia lixula sea urchin, obtained from eggs pretreated with KYR-12 serotonin analog or A-83 dopamine analog, develop quite normally. At the same time they have a sharply decreased supersensitivity to cytostatic analogs of "prenervous" transmitters; usual sensitivity to this analogs does not change. Besides, both the supersensitivity and the usual sensitivity stop decreasing upon an increase in the density of density of experimental embryos in the incubation medium.
