[The effect of antiparkinson preparations on the self-stimulation reaction of rabbits in a helium-oxygen environment under increased pressure].

The authors studied hypothalamic self-stimulation of 30 rabbits in hyperbaric heliox after intraperitoneal injections of L-DOPA, melanostatin, and cyclodol. The frequency of self-stimulation was decreased with 40 atm of heliox. After L-DOPA administration, a reduction of self-stimulation was twice less than that in heliox without pharmaceuticals.
