猫脳レンズ核の細胞構築学的研究ならびに痙攣時の組織化学的研究 第3編 実験的痙攣猫脳レンズ核各分野のケトエノール顆粒に関する組織化学的研究

Ten percent pentazol solution was experimentally injected in cats and the change of the ketoenolic granular (KEG) due to convulsion were histochemically investigated by the carbol fuesin jod method. 1) The KEG in nerve cells increased more markedly in each area of the convulsion cases than that of the nonconvulsive cases. 2) The increase of KEG in nerve cells during the convulsion was in order of Pd, Pv, Pa and pallidum. 3) The large cells in putamen showed more increase of KEG than small cells (receptive cells) especially markedly in large cells in putamen dorsalis posterior. 4) KEG in Nissl grey substance decreased on the contrary, in the convulsion cases than the nonconvulsive cases in each area excepting those in pallidum and the order accorded with the increase of KEG in cells. 5) Pallidum differed from other areas and showed slight increase of KEG in cells, and also the Nissl grey substance showed considerable distribution of KEG in nonconvulsive cases and no decreased of KEG caused by convuslion. 6) In the nucleus lenticularis, the putamen dorsalis posterior, especially its effective cells seem to participate mostly to convulsion.
