JOURNAL FREE ACCESSUniversity School of Medicine (Chief: Prof. M. Morimoto, M.D.)The Brain Research Institute, Niigata University School of Medicine (Instructor: Assist. Prof. N. Maruyama, M.D.) Ist Department of Physiology, Niigata University Scool of Medicine (Chief:Prof. A. Niizima, M.D.) Unitary activities were recorded from the supe- rior colliculus in the rabbit by means of super-fine microelectrodes during elicitation of optokinetic nystagmus.
The recorded activities of 76 units were classified into the following 6 types.
(1) In four units the frequency of discharges in-creased within a certain space of time during nys- tagmus regardless of its direction.
There was a difference in the frequency or the discharge pattern between the discharges concurrent with nystagmus toward the left and those concur- rent with nystagmus toward the right.
(2) In three units the frequency of discharges decreased during nystagmus toward either side.
The degree and time of inhibition depended on each unit but on the direction of nystagmus.
(3) In seven units the frequency of discharges increased within a certain space of time during nystagmus toward one direction but it did not change during nystagmus toward the other direction.
In three of these 7 units the response consisted of a burst of spikes corresponding to the peak of the nystagmographic curve. In the other 4 the frequency of discharges increased during the slow phase of nystagmus.
(4) In five units the frequency of discharges decreased during nystagmus toward one direction and did not change during nystagmus toward the other direction.
(5) In one unit the frequency of discharges increased within a certain space of time during nystagmus toward the left, while it decreased within a certain space of time during nystgmus toward the right.
(6) In 56 units the frequency of discharges did not change during nystagmus toward either direction.
It was difficult to establish any relationship between anatomical location in the superior colliculus and these response types mentioned above.View full abstractDownload PDF (4025K) -
Part I. Vestibular Reflexes Under General Anesthesia[in Japanese]1964 Volume 67 Issue 3 Pages 228-237
Published: 1964
Released on J-STAGE: March 19, 2008
JOURNAL FREE ACCESSUnder nitrous oxide-oxygen-ether anes thes is the transtympanic membranous labyrinthotomies were carried out for the relief of recurrent attacks of vertigo in two patients of in the end stage of Meniere's disease.
Electroencephalogram (leads in the left or right temporal and in the left or right parietal areas), electronystagmogram (leads in the outer canthi of the eyes), plethysmogram, galvanic skin reaction, electrocardiogram, respiration were simultaneously recorded with an 8-channel electroencephalograh.
The results obtained were as follows :
1. Patterns of the quick ocular movement and vestibular nystagmus produced by labyrinthine sti mulations were modified in their forms dur inggeneral anesthesia, and vestibular ocular movements produced by stimulating the labyrinth or unilateral labyrinthotomy were observed in relatively deep general anesthesia.
2. An imate relationship between the depth of anesthesia and ocular movements was recognized and this fact shows the ocular movements can be utilized as one of the indicators to show the depth of anesthesia.
3. Vestibulo-vegetative reflexes were already suppressed in the early stage of general anesthesia.
Vestibular influences upon various body activi. ties such as electroencephalogrm, eye-movement, galvanic skin reflex, plethysmogram, electrocardiogram and respiration were discussed.View full abstractDownload PDF (1894K) -

JOURNAL FREE ACCESSThe vestibule-ocular and vestibulo-vegetative reflexes were polygraphically studied on two patients with Meniere's disease in whom unilateral labyrinthotomies had been carried out.
Electroencephalogram, electronystagmogram, plethysmogram, galvanic skin reaction, electrocard iogram and respiration were simultaneously recorded in the patients recovering from general anest hesia and for 52 hours after the operation.
The results obtained were as follows :
1. Spontaneous nystagmus in the recovery stage from the anesthetic condition was towards the unoperated side, and gaze nystagmus, also remained.
2. In the awakened condition from anesthsia, spontaneous nystagmus were more frequently recognized in eyes covered or closed than in eyes opened.
3. During natural sleeping condition, spontaneous nystagmus and some vegetative phenomenawere extremely suppressed.View full abstractDownload PDF (570K) -

JOURNAL FREE ACCESSi) Using an electro-mechanical switch, we delivered speech alternately to both ears. Subjects who were tested were a group of 35 normal young adults and a group of 39 healthy older individuals.
Methods of examination were as follows ;
A. Monaural discrimination of mechanically resynthesized interrupted speech.
B. Binaural discrimination with aural alternation of stimuli.
C. Monaural discrimination of interrupted speech.
i) The relationship between interrupted frequency rate and speech discrimination for monaural and binaural alternating hearing was investigated.
In case of monaural hearing, the higher the rate of interruption, the better the disrimination ; however, in case of binaural, the discrimination was constant regardless of interruption frequency.
iii) When interrupted speech is introduced into one ear or alternatively introduced into both ears, the discrimination score of the aged lowered compared with the young adults.
iv) Analyzing the confusion matrix of speech discrimination, we divided the central mechanism of binaural hearing, i. e., binaural summation of hearing, into two parts ; pseudo- and real summation of binaural hearing. In advanced age, the part of real summation decreased.
v) As for the clinical application of interrupted speech, the diagnostic values of the central deafness and of the malingering of unilateral deafness were discussed.View full abstractDownload PDF (1364K) -

JOURNAL FREE ACCESSTo study the value of the writing test as a clinical evaluation of vestibular function the authors have conducted an investigation on 62 cases of the labyrinthopathy and 23 normal cases, comparing with past-pointing and stepping test. And the caloric test were also performed on all cases.
The writing test was positive in 64.5% of 62 patients, the stepping test in 77.4% and the pastpointing test in 25.8%.
As the normal threshold of these tests the following standard were used. writing test 10- inclination stepping test 30- deviation in 50 stepping past-pointing 5cm
The inclination in the writing test was mostly found to the side of the slow phase in the caloric test, although several cases resulted in negative finding and two cases revealed contra lateral inclination.
These paradoxical reaction were found also in the stepping and the past-pointing test, but not in the rotatory test.
There was found no consistency in these static tests of vestibular function. As a conclusion the authors emphasize that the volantary muscle reflex mechanism of the vestibular labyrinth is highly complicated and in inconsistency of the reaction due to constitutional differrences must be considered in evaluation of these tests.View full abstractDownload PDF (383K) -

JOURNAL FREE ACCESSThe people grouped together here as being susceptible to seasickness are otherwise normal individuals with normal vestibular function.
The results of the present investigation can be summarized as follows :
(1) Neither the resistant nor the susceptible groups show any spontaneous vestibular signs.
(2) The longer duration of nystagmus and dizziness in both caloric and rotatory tests is generally associated with the higher susceptibility to seasickness, while resistant individuals are usually free of dizziness during the tests.
(3) Susceptible group shows the characteristic pattern in our rotatory pattern test and caloric pattern test.
(4) Functional unbalance of bilateral labyrinths has no significant relation to the susceptibiltity to seasickness. The test of semicircular canal system is also important to the study of seasickness.View full abstractDownload PDF (2323K) -

JOURNAL FREE ACCESSIn order to explore the relationship of the nasal septum deviation with the localization of epipharyngitis, observation was made on the difference in the cytologic picture of epipharyngeal mucosa and in some clinical symptoms between right and left side in 160 cases of nasal septum deviation of various degrees. The results obtained are as follows. 1) With the increase of deviation the nasal obstruction became stronger on the convex than on the concave side, and situation was same for the pain on touch of the applicator with the epiphary ngeal mucosa. 2) The exfoliation of ciliated epithelial cells was of a higher degree in the epipharyngeal mucosa to the convex side as compared with that to the concave side, and also the degree of their deformation was higher on the convex side in majority of the cases. 3) In not a few cases there were remarkable appearances of goblet cells, leukocytes and lymphocytes in the epipharyngeal mucosa to the convex side. 4) The foregoing findings seem to indicate that the epipharyngeal inflammation in the nasal septum deviation is rather strong in the region to the con- vex side of deviation.View full abstractDownload PDF (1753K) -

JOURNAL FREE ACCESSAhistopathological study on 53 cases out of 65 cases of tongue cancer which underwent glossectomy inthe department of Otorhinolaryngology, Nagasaki University Hospital during the period from 1952to 1963, was studied.The results are as follows
1)All cases were squamous cell carcinoma andof these29cases were cornificated and24 cases not cornificated.
2)The clinical appearances of lingual cancers were classified into six types in the first partof this study. The histological findings of eacht ype. werere peported.
3)The grade of(tumor) cell classification of lingual cancer was classified into five grades and the relationship between these grades and postope- rative prognosis were investigated, but no definite correlations were not found. 4)The histological findings of the surrounding tissues of lingual cancer, namely round cell infilt- ration and fibrosis, were observed, but concerning its postoperative prognosis no significant meanings were found However, in many cases remarkable collaterale hyperplasia of the epithelium were found and this might be a significant in determi- ning the dissecting limit in glossectomy.
5) Reports of the distant metastasis is rare in the liturature and in this report the onyl one case of pulmonary metastasis was found at autopsy. Metastasis in the neck lymph nodules was founud in 9 cases ant of 24 in which all lymph nodes were obs- erved systematically. Out of 24 cases lymph nodes were palpated in 11 case and in 6 cases histological metastasis was confirmed.
The histological construction of the tumor tissue in the metastatic lymph nodules and in the primary tumor in the longue was similar.View full abstractDownload PDF (2219K) -

JOURNAL FREE ACCESSLymphangioma originating from the sphenoid sinus was found in a 23 years old male, whose chief complaints were frequent epistaxis, nasal obstru ktion and dull headache. On admission there was severe an emia. Nasal mucosa was edematous but tumor mass was not visualized. The paranasal sinuitis was demonstrated in sinus X-ray. Then we found a large tumor mass which was situated n the left sinus by " polisinektomie" This tumor mass was removed as "enbloc" by means of external transantral sphenoidectomy. Postoperatively he had been free from the above complaints. Lymphangio- ma of the nasal sinus is rare and only few cases have been reported in literature. Histopathology of the tumor and its surgical management are dis_cussed. We stresses the importance of "enbloc" disse_ ction of this tumor.View full abstractDownload PDF (1816K) -
