The action of PRP is characterized by the pronounced activation of the back
ground activity (BA) of the brain spinal cord, and the degree of the activi
ty depends on BA initial level. The typical peculiarity of Vipera raddei ve
nom influence is the initial increase in frequency of BA with subsequent de
pression. A preliminary injection of PRP has a protective effect at subsequ
ent influence of venom. In animals with hemisection the PRP increases the d
ecreased activity of neurons on injury side. Taking into consideration the
protective peculiarities of PRP in the relationship to snake venom and the
possibility of the latter to stabilize and prolong the action of drugs (in
the case of PRP) combined with them, it is supposed that the mentioned use
of the combination in clinical practice will be perspective. The data obtai
ned testify the PRP to be a neuroprotector against many toxic compounds for
