  • Abstract
  • Look Inside

The penetration of P32 into the nervous tissue (sciatic nerve and brachial plexus of Rana pipiense or Bufo vulgaris japonica) was studied and the result may be summarized as follows.

1) The intensity (penetration quantity) in-creases within three hours along with the passing of time.

2) The uptake of P32 by nerves has been studied at temperatures ranging from -2℃ to 35℃. In accordance with Arrhenius equa-tion, the activation energy of the transfer pro-cess, μ is about 8500 calories in expriment and 5060 calories in experiment Ⅱ. The ma-gnitude of this value indicates that the trans-fer process is physical rather than chemical in nature.

3) By addition of various drugs the penet ration was almost inhibited.

4) The uptake of P32 by the trichlor acetic acid soluble portion of nerve is much greater than that by the insoluble portion.

5) The transferring of P32 seems to take place by diffusion.
