ジャーナル フリーThe vestibular membranous labyrinth of the guinea pig and the rabbit has been studied by electron microscopy.
1) Normal structure of the epithelium of the Planum semilunatum is as follows :
The simple epithelium contained many mitochondria, well-developed rough-surfaced endoplasmic reticulum, vacuoles, Golgi complexes and multivesicular body-like structures.
Microvilli-like processes were found on the surface facing endolymph.
In the basal part of the epithelium the plasma membrane was deeply infolded into the basal portion of the cytoplasm forming a complex doublemembrane. Between the basal infolding a great number of mitochondria were found.
The features of the ultrastructure resembled closely to those found in the kidney tubules and choroid plexus.
These findings suggest that this epithelium plays significant role in the water transport in the labyrinth.
2) Two kinds of nerve endings were found in the hair cell of the rabbit's Crista ampullaris. One is packed with vesicles 300-500A in diameter (granulated nerve ending) and the other with few granules (non-granulated nerve ending).
After electrical stimulation of the 8 th nervesubmicroscopic changes were observed on the granulated nerve endings. With stimuli of 200 pulses per second for 10 minutes a decrease in the number of synaptic vesicles was observed. It may be suggested that these are efferent nerve endings.
However, more substantial evidence may be needed to distinguish the efferent from the afferent endings.
3) There were found pigment cells and pigment granules in the epithelium of the utricle and the saccule, the epithelium of the Crista ampullaris and the portion of the subepithelium of the Planum semilunatum. These cells and granules are considered melanocytes and melanin. Melanin granules with a diameter 0.3_??_0.7 showed strong electron density. Melanocytes contained a few mitochondria.
4) In the rabbit's sensory hair three types of stereocilia were distinguished; 1) a large one (0.4μin diameter), 2) a fused one (stereocilia and stereocilia) and 3) another fused one (stereocilia and kinocilia).抄録全体を表示PDF形式でダウンロード (6769K) -

ジャーナル フリーAn apparatus for the measurement of the acoustic impedance of the middle ear at the tympanic membrane was described. The measurement of fers a possibility of studying the acoustic structure of the middle ear, which contains not a single but several anti-resonance peaks. The method employed makes use of a main rigid-walled tube linked to an exponential horn with an extended tube of 4.7em length which is inserted into the auditory canal. The source of sound is attached to the main rigid-walled tube which incorporates a travelling probe microphone which is operated by a hand crank.
The results of measurements in normal subjects sand in those with conduction affections exhibi. ted acoustic impedance ranging from 900 to 3000cps according to specific property of the exponential horn. The normal impedance is higher in a lower frequency range and lower in a higher frequency range, and is lower than that of otosclerotie ears with fixed stapes, chronic adhesive otitis or tubal occlusion. On the other hand the impedance of the ears with an interrupted ossicular chain is markedly low compared with that of the normal ears. Consequently, results obtained in the living subject can be applied clinically to the assessment of middle ear functions.抄録全体を表示PDF形式でダウンロード (1633K) -

ジャーナル フリーIt has been said that interaural time and intensity difference play a greatest role in the directional hearing.
An apparatus ideally suited in examining the correlation of these two factors which can produce any interaural time differences without changing interaural intensity difference was made.
In thisreport, the mechanism of the apparatus and the results obtained were explained.
In the complex sounds (music, speech and whitenoise), the just noticeable difference in time was -smaller than in other sounds(continuous and inter rupted pure tones), and it was too large to be estimated in 2, 000cps pure tone.
By the centering technique, we examined the interaction between interaural time and intensity -difference and compared time vs, intensity ratios (*t/*i)of 1/2 taveband-noises.
It was found that the time vs.intensity ratio was effected by both intensity and frequency of test tone, and that bilaterally lateralized two sound images were recognized as Banister and others reported when the test tone was too loud or inte.
raural time difference was too large.
Time vs.intensity ratio was the smallest in the 600_??_850cps band-noise(SL.40dB).
When test tone was interrupted, the results were different from that of continuous test tone, as follows;
1)A sound image located more clearly.
2)Even2, 000cps pure tone yields a clear soand image.
3)Time vs.intensity ratios were smaller in general.
4)Two sound images which lateralized to each earin continuous test tones disapPeared andasingle clear image was heard.抄録全体を表示PDF形式でダウンロード (998K) -

ジャーナル フリーIn an attempt to overcome the problem of mastoid cavity in classical tympanoplasty, a new obliteratory technique of the mastoid is presented which consists of the conservation of the ear canal and the use of temporal fascia graft of the car drum.
The operation is undertaken through postauricular approach. After radical mastoidectomy the posterior bony wall of the ear canal is completely resected. Meatal skin, however, is conserved in situ without making any plastic procedure. Depending on pathological conditions of the ossicular chain the type of tympanoplasty of choice is determined after Wullstein II, III or IV. Temporal fascia is then inserted underneath the perforated drum. Finally postauricular wound is sutured in double layers leaving the mastoid cavity in dead space. This technique allows reconstruction of the nearly normal ear canal, and enables a rapid healing needing practically no after-care and presents good results in hearing.
The author explained the detail of technical procedure with a report of 16 cases and extended to the historical review of Barany's radical operation and fascia graft of the middle ear. In his opion the "skin growing" over the fascia graft seems to be more useful in making the middle ear than the "skin grafting" of the drum.抄録全体を表示PDF形式でダウンロード (585K) -

ジャーナル フリーIn the first case, of a54 year-old woman, the decompressions-method of fissura orbitalis superior by transethmoidal route was performed after complete pansinectomy. The rhynogenous oculomotor paralysis improved soon after the operation and gradually disappeared.
In the second case, of a 14 year-old boy, there wrs osteomyelitis frontalis chron. with orbital phlegmon of dental origin sixteen months after pansinectomy.He was operated three times, In the last successful operation involved osteomyelitic bony tissues of os frontale were extensively removed and the trochlea was asacrificed. It was very lucky there was no subjective double vision two months after operation.
In the third case, of a 52 year-old woman, cause of the orbital apex syndrom was not determined about nine months.
During pansinectomy a severe necrotic part of the posterior ethmoidal cells near the fissura orbitalis superior was removed. Three months after opsration v.s. 6/60 improved to 6/20 and the paralysis of oculomotor nerve also improved.抄録全体を表示PDF形式でダウンロード (5445K) -

ジャーナル フリーClinical and pathological studies of papilloma growing in nasal and paranasal cavities were made in 6 cases whicn have been treated surgically and radiologically for a period of about 15 years in the Oto-Rhino-Larngological Clinic, Hirosaki University School of Medicine.
Age distribution of these 6 cases ranged from 43 to 64 years and all were male. The chief complaint of these was mostly nasal obustruction caused by papillary tumor persisting for 1 to 20 years prior to their first consultations. However, cheek swelling appeared initially in 1 case, of which papilloma was associated with malignant change.
Papilloma developed in the left nasal and paranasal cavities in 5 cases and in the right in 1 case, and their x-ray films taken by nose-chin projection revealed predominate opacity limited in the nasal cavity and the ethmoidal region on the 1 side only.
In all 6 cases, no metastasis was found, despite the long duration of their clinical courses. Not only polypous proliferation of the mucous membrane but also destruction of bony wall surrounding paranasal cavities were most characteristic findings of this growth.
One case out of 5 treated with partial resection of maxilla (Denker's Method), followed by irradiation therapies died 2 months after the operation from local exacervation of transitional cell carcinoma which was probably considered to be malignant change of papilloma, but the remaining 4 cases had no recurrence during a period of 6 months' to 10 year's follow-up.
The specimens of mucous membrane removed were characterized grossly, by edematous thickening and folding. Microscopically, they were characterized by vivid inward growth of superficial epithelial layer, which consisted of cylindrical, transitional or occasionally squamous epithelium, with underlying basement membrane.
In this series, clinically, there was no malignant case, excepting the above-mentioned case with malignant transformation of papilloma, but histologically, polymorphism and irregularity of cells and hyperchromasia of nuclei suggested latent active signs of malignant change were detected in one other case with no clinical malignant evidences.抄録全体を表示PDF形式でダウンロード (4903K) -

ジャーナル フリーCytologic observation was made of the smears from the epipharyngeal mucosa in 160 cases of epipharyngitis, with some reference to the relationship of its results with the clinical symptom. The findings obtained are as follows.
1) The exfoliation of ciliated epithelial cells was of a much higher degree as compared with the normal cases.
2) A fairy good parallel relationship was found between the deformation of ciliated epithelial cells and the quantity of leukocytes.
3) A tendency of lymphocytes increase with. the increase of goblet cells was seen.
4) Almost parallel relationship was obtained between the exfoliation of ciliated epithelial cells. and the pain on touch of the applicator with the epipharyngeal mucosa.抄録全体を表示PDF形式でダウンロード (1535K) -

ジャーナル フリーThe Semon-Rosenbach's rule of the vocal cords in recurrent nerve paralysis has been discussed for a long time by many authors, and it is recognized that this theory does not give a law which can be generally applied to all cases of recurrent nerve paralysis.
In this work peripheral distribution of the laryngeal nerve, the laryngeal reflexes and the vulnerability of the recurrent laryngeal nerve was studied by using the electromyogram.
1) Peripheral distribution of the laryngeal nerve of man and dog was found to be anatomically and functionally similar.
2) The laryngeal reflexes evoked by stimulation of superior laryngeal nerve were studied and discussed.
3) The vulnerability of abductor nerve fibre and adductor of recurrent laryngeal nerve, to compression, cooling, drugs and torsion, was studied. It would be reasonable to conclude that abductor nerve fibre is more vulnerable than adductor.
4) Electromyograms were taken of each intrinsic larngeal muscles under a direct vision when the larynx and these muscles were exposed to view during the precedure of performing Woodman's laryngoplasty on 2 cases of laryngeal paralysis. It was found that, even in cases of abductor paralysis, muscular activity of the abductor muscles was still evident. The cause of the socalled bilateral abductor paralysis was discussed.抄録全体を表示PDF形式でダウンロード (5412K) -
