ジャーナル フリーThe role of the extrinsic laryngeal muscles in phonation was experimentally investigated on adult dogs. Phonation was artificially induced by blowing the air through the glottis while closing the glottis by delivering electrical stimuli to the laryngeal nerves. Changes in voice were evaluated using sound spectrograph when individual and/or assorted extrinsic laryngeal muscles were stimulated.
As a result, the following conclusions were obtained.
1) Contraction of each individual muscle generally provided insignificant effect on voice.
2) Simultaneous assorted contractions of a selected muscle among the extrinsic laryngeal muscles with the cricopharyngeal muscle rose a pitch.
3) Simultaneous assorted contractions of a selected muscle with both the cricopharyngeal and cricothyroid muscles resulted in an obvious pitch rise.
The mechanism of pitch rise by independent and combined contractions of the extrinsic laryngeal muscles was discussed and the role of the extrinsic laryngeal muscles in the phoniatric regulation of the larynx was stressed.抄録全体を表示PDF形式でダウンロード (2793K) -

ジャーナル フリーFour patients with nevocellular nevi originating in the external auditory canal were reported. There were 40 cases of neoplasmas originating from nevus cells of the external auditory canal reported in the Japanese literature, and in 9 of the 40 patients these neoplasms were reported as malignant. We reviewed the reports of these 9 patients and found that there were only two patients in which malignant melanoma was definitively diagnosed.
In our otorhinolaryngological field, neoplasms originating from nevus cells of the external auditory canal are usually called as melanoma of the external auditory canal or pigmented nevus. This terminology, however, is obscure, and we proposed the clinical and diagnostic term, nevocellular nevus, which clearly describes its origin.抄録全体を表示PDF形式でダウンロード (2619K) -

ジャーナル フリーClinical observations were made on patients with severe Bell's palsy with reference to their facial expressions and nerve regeneration. The state of nerve regeneration was estimated by means of standard and evoked EMG tests.
The results were as follows.
1) Judging from EMG findings, complete regeneration of paralyzed nerve was never achieved in certain cases of over 50 years of age even one year after the onset.
2) Except for those cases mentioned above, complete nerve regeneration was generally ascertained by EMG tests. This would indicate that the route for nerve regeneration is preserved sufficiently even in patients with severe Bell's palsy.
3) Except for young children, however, complete recovery of facial expressions was hardly obtained even after electromyographycally-complete nerve regeneration and apparent atrophy of the facial muscles was often observed.抄録全体を表示PDF形式でダウンロード (1093K) -

ジャーナル フリーWith the Bekesy type audiometer, the relationship between the amplitude of Bekesy tracing and the attenuating condition was studied. The attenuating step is changable at 0. 5, 2. 5, and 5.0dB. The attenuating speed is also changable at 1, 2, 3, 4 and 5dB/sec. For this study 7 cases with normal hearing and as many with cochlear hearing impairment were chosen.
Based on the results, the optimal attenuating condition to evaluate the recruitment phenomenon was also investigated.
The following results were obtained.
1) The amplitude of Bekesy tracing showed a tendency to decrease with the increase of the attenuating steps. In the test of continous tone of 5dB attenuating step, those with normal hearing showed remarkable narrowing of amplitude. Those with cochlear hearing impairment showed the same narrowing in the test of continuous tone of 2.5dB step.
2) As the attenuating speed X increases, the amplitude Y also increases. The relationship between X and Y was shown as follows, Y=(a)X+(b). (a) is assumed to correspond to the reaction time. The value (a) appears to decrease greatly when the cochlear impaired ears and the normal ones at 5dB attenuating step were stimulated with continuous tone. Hence remarkable narrowing of amplitude, the shortening of reaction time is assumed to concern. (b) is assumed to be a threshold deviation of the duration of tone. The value (b) decreased only when normal ear was stimulated with continuous tone at 5dB step. In the test of 5dB attenuating step, a phenomenon, which is similar to the recruitment, is thought to have taken place.
3) The optimal attenuating condition to test the recruitment phenomenon are as follows. Among 0.5, 2.5, 5.0dB attenuating steps, 2.5dB was the best. Among 1, 2, 3, 4 and 5dB/sec attenuating speeds, 4dB/sec was the best.
4) With the use of this optimal attenuating condition, the accuracy of diagnosis of cochlear hearing impairment and the shortening of examination time are expected.抄録全体を表示PDF形式でダウンロード (665K) -

ジャーナル フリーThis article presents a tutorial introduction to the acoustic microscope in relation to the measurement of the mechanical property of biological tissues.
The greatest advantage of the acoustic microscope is that it can provide following two features simultaneously: (1) high resolution, and (2) information on mechanical properties. As for(1), a resolution in the order of 1μm is obtained when an ultrasonic wave in the order of 100MHz is used. As for(2), in a simplest case, a reflected image conveys the information on elastic property whereas a transmitted image conveys the information on viscous property.
As an example, two pictures are presented;one for a thin specimen(10μm thick)and the other for a thick specimen(2mm thick)of a human vocal fold tissue both taken by an acoustic microscope of the reflection type. The results were as follows: (a) The picture for athin specimen was similar to a transmitted image instead of a reflected image when the specimen was placed on a slide glass. (b) The picture for a thick specimen was successfully taken in reflected mode.
A preliminary discussion concerning the mechanical properties of the vocal fold tissue is presented. A detailed analysis of the image in relation to the tissue property remains for future study.抄録全体を表示PDF形式でダウンロード (1106K) -

ジャーナル フリーMorphology and metabolism of the otoconia were studied by scanning electron microscope and x-ray microanalyzer.
The experimental animals (albino guinea pig) were divided into two groups. The first group served as control and the second group were treated with streptomycin sulfate (SM). In control animals, the shape of the otoconial crystal of the utricular macula was cylindrical with two pointed ends. In this group, unusual otoconia were also observed in the deep layer of the otoconial crystalline layer. Furthermore, some decrease in number of otoconia was noted in 40% of this group.
All of SM administrated animals showed marked reduction of otoconia. This indicates that SM disturbs the metabolism of the otoconia. Two months after cessation of SM injection, it was found that the otoconia on the otochnial membrane increased in number, suggesting regeneration of the otoconia.
There were small granules observed on the surface of the otoconial membrane and also on the other side of the otoconial membrane which faces the sensory epithelia. These granules contained certain amount of calcium. These findings suggest that the small granules are a precursor of the otoconia. Numerous granular substances were observed on the surface of the sensory epithelia. It was also found that these granular substances were transformed into the otolithic crystal. There were many protrusions from the surface of the supporting cells surrounding the sensory hair cells. These protrusions and granular substances contained some amount of calcium. Some specimens were also freeze-cracked and observed in the same way. In the cracked specimens, small granules were found in some cells and these granules also contained some amount of calcium. Therefore, it is suggested that precursors of otoconia may be secreted from the supporting cells.
On the surface of the perimacular dark cells, numerous otoconia were observed. They appeared fragmented and shrunken. Their surface was irregular like a pumice stone. These deformed otoconia contained smaller amount of calicium than the normal.
The author found new mesh-like substances on the surface of the dark cells. These substances were various in shape and had many micropores. It was concluded that the calcium ions are actively absorbed by dark cells and the mesh-like substance is an organic matrix of the otoconia.抄録全体を表示PDF形式でダウンロード (5982K) -

ジャーナル フリーTwenty seven cases with nasopharyngeal carcinoma (NPC), who are below forty year old, were investigated during past ten years(1970-79)at our clinic. The cases were examined from various modalities, such as histological classification, diagnosis, treatment and prognosis.
Following results were obtained.
1. Histopathologically, the vast majority of the tumors in the younger age group are the undifferenciated type.
2. The neck mass is the most prevalent chief complaint in the this group.
3. At the first hospital visit, the stage of many cases in younger age group is already advanced. Therefore, the early diagnosis should be emphasized.
4. The prognosis is poor, comparing with elder patients. The cause of death is distant metastasis in almost all cases. To improve the prognosis of NPC in the younger age group, the appropriate adjuvant chemotherapy and immunotherapy are necessary.抄録全体を表示PDF形式でダウンロード (385K)
