各種脳組織破壊方法に関する実験的研究 第1編 猫脳淡蒼球破壊周辺部におけるコリンエステラーゼ活性値および遊離アミノ酸窒素量に関する研究

1) An attempt was made to study variation of cholinesterase and free nitrogen of aminoacids at globus pallidus lesion produced by various methods, such as oil-wax-, etopalin-injections and electrical coagulation. Eight normal cats for each these three groups were utilized in this study. 2) Both cholinesterase and free nitrogen of aminoacids were decreased in value for the first postoperative week in case of the oil-wax injection. They would, however, both come back to the normal values within the third postoperative week. 3) In case of the etopalin injection, the values of both cholinesterase and free nitrogen of aminoacids were considerably decreased for the first postoperative week and would not come back to the normal values within the third postoperative week. 4) The electrically coagulated lesion manifested the same tendency of the variation of the two substances as the oil-wax method for the first week. However, the recovery is comparatively sharp in contrast to the latter.
