RESUMO
The 45Ca2+ absorption by the different tissues under PTH influence was studied by the radioisotope method as dependent on the incubation time. In all cases it was found that the tissue faculty of 45Ca2+ accumulation increases especially in the early period of the incubation. This effect results from a more intense activity of the membrane channels.

The reflex reactions of the cat spinal cord were studied in chronic alcohol intoxication The extension of the monosynaptic response latency with simultaneous decrease of its amplitude and the suppression of posttetanic potentiation as well as the breaking of inhibitory processes in spinal cord were found after i. v. injection of alcohol. The disordered functional stat of the spinal cord's segmental apparatus seems to be due to depolarizing effect of alcohol and may be one of the causes of the motor breakdown in alcohol intoxication.
