[Effects of noopept and cortexin on the behavior of matured rats treated with corticoliberin or 70-kDa heat shock proteins in early ontogeny].

Young Wistar rats aged 4 days were injected intraperitoneally with corticotropin releasing hormone (CRH), which is an agent activating the stress system, or 70-kDa heat shock proteins (HSP-70)--intracellular shaperons, possessing antistress properties. In grown adult rats aged 90-100 days, the effects of nootropic drugs noopept and cortexin (1 mg/kg, i.p.
