Abstract

The effect of stereotaxic administration of tremorine and oxotremorine into four brain areas has been investigated using rats. Tremorine produced tremor significantly higher than control after administration into the globus pallidus, caudate nucleus, and substantia nigra. Oxotremorine produced tremor significantly higher than control only after injection into the substantia nigra. Dyflos injected into the caudate nucleus produced tremor. No change in the tremorgenic action of tremorine was observed after the simultaneous intracaudate injections of atropine and tremorine, and dyflos and tremorine. Intraperitoneal atropine reduced the tremorgenic action of an intracaudate injection of tremorine.

大鼠脑内立体定向注射氧tremorine和tremorine致震颤作用的研究
用大鼠研究了立体定向给药tremorine和oxtremorine对四个脑区的影响。在白球、尾状核和黑质给药后,Tremorine产生的震颤明显高于对照组。仅在黑质注射后,氧tremorine产生的震颤明显高于对照组。尾状核注射Dyflos产生震颤。同时在颅内注射阿托品和tremorine, dyflos和tremorine后,tremorine的致震作用没有变化。腹腔注射阿托品可降低卵孔内注射震颤碱的震颤作用。
