ジャーナル フリーElectric decalcification was applied to prepare the specimens of guinea pig labyrinth and influences of this procedure upon ganglionic cells of the acoustic nerve were histologically studied.
The results were as follows:
1. It took more than 12 hours to secure perfect decalcification on animals weighted about 300 grams.
2. In the cases decalcificated for more than 48 hours the specimens were less stainable to thionin.
3. In the cases decalcificated for less than 36 hours no remarkable changes were observed with the exception that protoplasma and nuclei were more or less deeply stained, and Nissl's granules were well preserved, while in the cases of decalcification for 6 days, contraction of cells, interspace bilding around the protoplasma, pycnosis of the nuclei, disappearance of Nissl's gra-nules etc, were observed.
It may be given as a conclusion that it is adequate to decalcify electrically from 12 to 36 hours when the labyrinth of guinea pig is examined.抄録全体を表示PDF形式でダウンロード (1886K) -

ジャーナル フリーWhat infuence could investigate to cochlear response when the middle ear apparatus were given the impairment and its repairment in free system? The results were as follows
; 1) On the experiment regarding the degree of loss and the location of the perforation in tympanic menbrane, some increase of loss was seen in the post-inferior perforation of the ear drum, but there was no remarkable difference between this and the other portions, and con-sequently, it was proved in the relation between size of the perforation of tympanic menbrane and cochesar response that the response had decreased in proportion to the size of the perfora-tion
. Next, when these perforations were closed by the artificial ear drum, there was scarcely any response in the small perforation, but in the middle and large perforations some effects of the response could be observed. The increase of the response in its efficacy was maximum at 800 cps; in general, the increase of the response in the lower and middle part of sound wass higher than that in the high part of sound. Moreover it was recognized definitely that the difference of effect depended upon the materials used for the artificial ear drum.
2) On the occasion that the function of facial nerves was paralized, a little increase of res-ponse could be observed at 2000 cps but in other frequencies the loss did not fall more than 5 db in the response.
When the function was stimulated, the increase of response would be observed just after the impetus; The response began to decrease as the time went on but the decrease stopped within 10 db in degree of the hearing loss.
3) In the case that the ossicular chain was fixed, two different phenomena appeared; when that fixation was incomplete, the impairment was observed in the low-middle part of sound, while it became perfect, the loss appeared running parallel with the fiducial line in all parts of sound. Again, on the occasion that the ossicular chain was blocked, the impairment appeared in rather than high part of sound showing 50 db in an average.
4) In the case that a continuous manipulations were done upon the middle ear apparatus, a definite change was observed in cochlear response every time the manipulation was done.
When the middle ear apparatus was repair using the artificial ear drum, the response inc reased 5-15 db in all cases.
With removal of ear drum and malleus after the opening of epitympanum,
In the other cases which had been repaired, no effect by artificial ear drum was observed.抄録全体を表示PDF形式でダウンロード (4267K) -

ジャーナル フリーInvestigations were made on the retation of the hearing and the disturbances of the con-ductive system in chronic infection of the middle ear, and the following results were obtained
1. In chronic infection of the middle ear, disturbances of the inner ear and absence of mobilization of the stapes account greatly for the loss of air conduction, and in cases of severe impairment of air conduction, the threshold of bone conduction was frequently enhanced. In the cases with impaired mobilization of the stapes, the loss of air conduction more than 50 db was noted in all cases, being more than 60db in most of the cases.
2. When the factors contributing to disturbance of inner ear were removed, the hearing thresholds were between 30 and 50 db in the cases whose ossicles were intact. There was no specific relationship between the size of the perforation of the ear drum and the loss of air conduction, but there was a tendency of greater impairment in hearing when the perforation of the drum was located in the upper posterior quadrant. The cases in which the ossicular chain was separated showed thresholds of 40_??_60 db. Cases with the mild caries of the ossicles without impairment of chain function showed the loss similar to that of the case with intact ossicles.
3. In chronic infection of the middle ear, the frequency characteristic showed largest im-pairment in the range of low to middle sounds, especially in the low tone zone.
Report 2. Test for changes in the ossicles by means of the sound probe
An attempt was made to examine the state of the ossicle by measuring the threshold of sound conduction by the ossicular chain by means of the sound probe. There was a clear diffe-rence in the thresholds between those with intact or mild caries of the ossicles but with retai-ned the ossicular chain function, and those with separated ossicular chain separated or with loss of mobilization of the stapes. Thus it may be stated that the sound probe can be used for evoluation of the ossicular function.抄録全体を表示PDF形式でダウンロード (2158K) -

ジャーナル フリーThe cochlear microphonics of the cat for bone conducted sound was recorded before and after fixation of the stapes and the round window membrane. The incudostapedial joint of the cat was destructed beforehand to isolate compressive bone conduction from other mechanisms, of bone conduction.
The decrease of the cochlear microphonic response was observed by 10 dB after fixation of the round window membrane.
By immobilization of the stapes the response was also reduced as much as 10 or 20 dB par-ticularly in frequencies from 1000 to 3000 cps.
The most severe impairment of the response was observed after blocking of both win-dows ; the impairment reached 30 dB in some cases.
We observed further the complete recovery of the impaired response after the removal of the fixation. Thus we ascertained that the impairment was caused by mechanical disturbance of the windows without any damage in the inner ear.
The fact that the response decreased by the immobilization of the stapes in animal experi-ment was in good agreement with Careart's notch of bone conduction curve in otosclerosis.
On the other hand, according to the theory of compressive bone conduction, the response or the hearing must increase with immobile stapes. So we concluded that the theory of comp-ressive bone conduction was not adequate for explaining experimental and clinical findings on bone conduction.
Consequently we concluded that the inertia of the inner ear conduction system must be considered as another mechanism of bone conduction.抄録全体を表示PDF形式でダウンロード (884K) -

ジャーナル フリーThe authors investigated the degree of the sagittal writing and the moving angles in healthy men and patients with oto-rhino-laryngological diseases. For the vestibular stimulation, a strip of gauze soaked in water at 18-C., was inserted to ear canal and eyes were closed.
We found the reactions of vestibular functions appeared on the test papers are distinguis hed plainly at forementioned each diseases.
The reactions are very precise but have never been observed,
The discovery rate of the fine vestibular reaction would be low if them only the sagittal writing method with closed eyes is employed.
The discovery rate remarkably increased by observations of comparison of different reac-tions by our method, in different ear diseases.
In future, we'll study by electricity or warming and so forth in stead of cold water for sti-mulation.
This report only shows a part of our experiments stand on the sagittal writing with closed eyes by Hoshino and Fukuda.
We believe, however, our method is the latest to know the slight reactions of vestibular functions.抄録全体を表示PDF形式でダウンロード (663K) -

ジャーナル フリーThe author investigated the auditory fatigue effect on 35 persons with normal hearing and 199 persons with various types of hearing difficulty.
First, on those with the normal hearing, the following studies were made, i. e. auditory fatigue effect when the frequency of the stinulating tone and the test tone are same or diffe-rent ; the comparison of the auditory fatigue effect of white noise and that of pure tone ; the variation of the auditory fatigue effect by the different stimulating method; and individual differences of the auditory fatigue effect.
In the next chapter, the auditory fatigue of pathological ears was investigated.
In general, the auditory fatigue effect in conductive deafness was smaller than that in the perceptive deafness.
In many cases of Meniere's disease, occupational deafness and deafness due to the admi-nistration of streptomycin, the recovery time of auditory fatigue was prolonged.
But in some patients with perceptive deafness, the recovery time was normal or reduced.抄録全体を表示PDF形式でダウンロード (2585K) -

ジャーナル フリーStudies of the sialogram of 49 cases of tumor of the parotid glands performed by the author from 1950 to March, 1957 have revealed the following findings:
1. In cases of benign tumor, the presence of stenosis, dilatation or abnormal distribution of the ductal system was found, and the absence of shadows was observed in sialograms of type VIII 1.
2. In cases of malignant tumor, sialograms showed discontinuation or intermittent brea-king-off of the duct and the seepage of the contrast medium into the adjacent tissue, and the absence of shadows was observed in sialograms of type VIII 2. The seepage of the contrast medium was noted also in the residual gland.
3. In view of the fact that examination or treatment which had been given before the sialography was performed made the picture confused, sialography should be performed prior to the start of a treatment.
4. It is sometimes impossible to determine the nature of the tumor by means of sialog-raphy. Nevertheless, it is important that an accurate diagnosis should be made concerning the extent and the location of the tumor before it is referred for surgery. And acccurate diagnosis of a tumor is not possible without sialograpey.
5. In taking the sialograms of the tumor, no only lateral view but also anteroposterior view should be taken. If it seems necessary, anteroposterior tomography should also be perfo-rmed.抄録全体を表示PDF形式でダウンロード (4363K) -

ジャーナル フリーExaminations of the distribution of the facial nerve, as well as of anastomosis between its branches, using total and subtotal parotidectomy specimens., remoned in our department from 4952 to June. 1957 have revealed the felleing results:
1. The cases which showed agastosis between the ascending and descending branches and those without anostomosis were equal in number. In the majority of the former, the anasto-mosis was seen on the lateral surface of the masseter muscle and the inner surface of the shallow lobe.
2. In 27% of the cases examined, no communication was observed between the branches of the facial nerve.
3. The cases examined might be classified into 8 types in accordance with the differences in ramification and anastomosis of th facial nerve. However, no definite corelation, was found between the types based on this classification and the types classified on the basis of the basis of the differences on alograms.
4. Although the branch of the facial nerve in the parotid gland measured over 1 mm in diameter in the majority of the cases, it measured less than 1 mm in some cases.
5. The best way to identify the facial nerve during the surgery of the parotid gland is to end it where its main trunk comes out from the stylomastoid foramen and enters into the pa-rotid gland.抄録全体を表示PDF形式でダウンロード (120K) -

ジャーナル フリーThe relation between the methods and the results of treatment on the patients of malignant tumor experienced frow 1946 to 1956 at the Department of Oto-rhino-laryngology, Yokohama University, School of Medicine, About the laryngeal cancers surgical as well as isotope treat-ment schowed good results in 85% of cases. Therefore the surgical treatment has same signifi for these diseases as the irradiation treatment does.
About the maxillary malignant tumors, I beliene that, as far as the surgical treatment is concerned, it is the most effective to make the resection as sufficient as possible, but it is also necessary to make the irradiation treatment as deep as possible.
About the pharyngeal malignant tumors, as far as my data are concerned, the application of the surgical and irradiation treatment at the same time schowed the most effective results
Above all, the neck dissection for lymph nodes has also an important significance for the malignant tumor in the regirn of ear, nose and throat.抄録全体を表示PDF形式でダウンロード (236K) -

ジャーナル フリーNo great differences were noted from existing reports regarding general clinical features, but, in those with subjective symptoms attentions to deformations of the cervical spine are necessary. Pure tone hearing of air and bone conductions become markedy lowered.
The audiographic classification revealed the "high tone sudden fall type" in many cases and almost of the belonged to the category of the nerve deafness.
Speech hearing was poor when compared with pure tone hearing, that of vowel sounds being especially impaired in many cases. According to the difference limen test, the impair-ment of hearing was due to degeneration of end or central organs, the latter tending to increase with advance in age. Normal hearing was noted mostly in those with normal blood pressure, but no intimate relation was noted between hearing and blool pressure. Normal hearing revealed practically no changes up to the age of 30 years, and after the age of 40 there was a significant fall in hearing. Individual differences were also minimal in those around 20 years of age, becoming however marked with advance in age.抄録全体を表示PDF形式でダウンロード (1558K)
