ジャーナル フリーIn the normal brain potentials of rabbits, the aetiology of the irregularity and the relationship between the chief-, the quick- and the slow-wave were considered as the same as in the human brain potentials.
In regard to the regularity, the normal brain potentials of rabbits were divided into three types; namely the regular, the irregular and the intermediate type. By means of “Thompson's Rejection Test” the chief-wave period of rabbits, which corresponds to the human alpha-wave, was 0.10-0.23 seconds in the regular type.
In the same animal, at the same locality, under the same condition, the variation in time of the average period over 100 waves was 5-10%, although the interval of the measurements was short. It corresponds very nearly to that in the human brain potentials.
The local difference was only a few per cent for the average period of about 400 waves, it was simlar to that of the human brain potentials and was not found significant, however, when it was statistically examined. The local feature, as maintained by Kornmüller, wasnot noticed.
As above mentioned, in regard to its regularity, variation in time and local difference of its average period, brain potentials, and essentially the same as the human's except the chief-wave-period was about 1.7 times longer than the human alpha waveperiod.抄録全体を表示PDF形式でダウンロード (509K) -

ジャーナル フリー1. 家兎を金属製円筒型固定器で固定した場合は固定直後より主波週期は延長し, 60分後に平均21.7%の延長を示し爾後漸次短縮する. 解放後20～30分で固定前の週期に復する.
2. 家兎を腹位緊縛固定すると主波週期の漸進的延長が見られ2時間後に平均17.8%の延長を示す解放後20～30分で固定前の週期に復する.抄録全体を表示PDF形式でダウンロード (332K) -

ジャーナル フリー1) MgCl2皮下注射で浅麻酔になるが深麻酔に入ると速かに危險症状を現わすCaCl2はMgCl2に対し拮抗作用を示す.
2) MgCl20.5gr/kg注射の場合主波週期の延長は60分後最大で平均12.2%の延長を示し爾後短縮の傾向を示すCaCl2注射で10～20分後正常状態の適期に復する.
3) MgCl21.0gr/kgでは主波週期の延長が60分後は殆ど同程度で平均約20%の延長を示し短縮の傾向はない. CaCl2注射後10～20分で正常状態の週期に復する.
4) MgCl21.5gr/kg注射の場合は主波週期の漸進的延長を示し, CaCl2注射による週期の恢復には長時間を要する
5. 深麻醉に入り危險症状を呈した場合はCaCl2注射によって週期の短縮を示さすに延長を続行する.抄録全体を表示PDF形式でダウンロード (336K) -

ジャーナル フリーLaryngeal sarkoma is comparatively rare, I recently encountered in a man aged 49, a rounded swelling on the right ary-epigrottic fold, mammillated in shape, irregular on the surface, circumscribed with a distinct bundary and so large as to obliterate the lumen of the larynx almost completely. At the same time, some lymph nodes on the right side of the neck had also enlarged to the size of an pigeon's egg. Histological findings indicated it was a fibrosarcoma of the larynx.
To the tumor was applied radon seed (15cm.) and radium (6420 mg. hr.), with a satisfactory result, that after a month's treatment the tumor nearly disappeared. The affected lymph nodes on the neck was removed completely by operation.
The patient, now three months since the discharge, does not show any sign of recurrence, although, of course, it is rather too early to discuss on the ultimate result.抄録全体を表示PDF形式でダウンロード (378K) -

ジャーナル フリーElectrical potentials of the human brain during and after the vestibular stimulation by means of the injection with cold water (5°C, 10cc) in the external ear canal were observed.
The results of the observation on several subjects showed considerable individual variation and supported the inference that the vestibular stimulation was not consistently effective, as is the case with the vesual stimulation, in depressing the α-rhythm of the human brain.抄録全体を表示PDF形式でダウンロード (220K) -
