[The effect of creatine phosphate on reflex transmission in the normal spinal cord and under hypoxic conditions].

The effect of phosphocreatine on reflex transmission in the spinal cord was studied in rats in vivo and in vitro. Low concentrations (10(-8)-10(-6) M) of phosphocreatine facilitated while high concentrations (10(-4)-10(-3) M) inhibited the amplitude of mono- and polysynaptic reflexes. It was found that phosphocreatine decreases the inhibiting action of hypoxia on test responses and accelerates restoration of the reflex transmission in the spinal cord.

[Effect of dopamine on the background and evoked activity of interneurons from isolated spinal cord segments of newborn rats].

The effects of dopamine on the background and dorsal root stimulation-evoked activity of spinal interneurons and on the field potentials in the dorsal horn were studied in the isolated superfused spinal cord of 11-18 days old rats. It was established that application of dopamine in concentration 1.10(-6)-1.

[Depolarizing action of dopamine on the endings of the primary afferent fibers of an isolated segment of the spinal cord in rat pups].

The effect of dopamine on the dorsal root potential was studied in the isolated superfused spinal cord of 12-18-day old rats. It was established that application of dopamine in concentration of 1.10(-9)-1.

[Depolarizing action of dopamine on the motor neurons of an isolated segment of the spinal cord in rat pups].

The dopamine effect on the ventral root potential was studied in the experiment with the isolated superfused spinal cord of 13-18-day old rats. It was established that application of dopamine in concentration of 1.10(-6)-1.
