ジャーナル フリーThe author described the electron-microscopic changes observed in the hair cells and nerve endings of the organ of Corti in the guinea pig after exposure to white noise at 120db.
The significant changes were found in the outer hair cells.
The mitochondria normally located inside the plasma membrane were displaced to the axial part by the sound stimulation. Numerous small granules (50-100Å) were found in the mitochondria in the infracuticular region after short exposure. After long exposure the mitochondria in this region lost their double cristal membrane, inclosed the agglomeration of osmiophilic granules and began to swell and degenerate. Sometimes degenerate mitochondria were seen to supranuclear region.
Next pronounced change seen was in the membranous layer, consisting of smooth surfaced Endoplasmic Reticulum (ER) arranged in lamellae. After exposure the axial ER system (Hensen body) increased in number and varied in form. Chains of spherical and irregular forms in upper half of hair cells were often found. On the other hand, the peripheral ER system beneath the plasma membrane often became anomalously thickened, consisting of the series of membranous layer.
The golgi-complex increased in supra nuclear zone after exposure.
A number of electron dense granules (200Å) were seen inside the plasma membrane and the outer membrane of the hairs after exposure.
The structural changes of cytoplasmic organella in the outer hair cells described above were more pronounced in the upper part of the cells, but in the infranuclear part no change were found even after long noise exposure.
In the inner hair cells, structual changes were less noticeable than in the outer hair cells.
The nerve endings under the outer hair cell showed two different kinds of nerve terminations, a small and a large one. The small nerve endings were found swollen with indistinct mitochondrial cristae after exposure, but the mitochondria in the large nerve ending less affected. No certain signs of reduction in number of synaptic vesicle in nerve endinge were seen.
The morphological changes in the hair cells and nerve endings became more marked with increase in duration of noise exposure.抄録全体を表示PDF形式でダウンロード (7532K) -

ジャーナル フリーSialographic study of the parotid gland was carried out, during and after the attack of mumps, in order to get information on the changes in the gland and ducts which might be caused by the disease. Diagnosis of mumps was based on seroimmunological tests, such as complement fixation tests, hemagglutination inhibition tests and skin tests (with intracutaneous inoculation). Roentgenographic appearances of the parotid were classified according to Kitamura's method. Roentgenograms were taken in lateral projection, after 40% moljodol had been injected into the Stensen's duct.
The shadow of the ductal system of the diseased parotid showed little difference from trom the normal gland; there were no marked changes exceptefor a tendency to reduced ramification of the duct in the incipience.
Sialograms of the gland itself varied with the stage of the disease. A shadow marked with small dapples intermingled with granule-shaped spots was seen at a stage soon after swelling had developed, with the caurse of the condition a shadow was seen to chauge to marked granuleshaped spots, intermingled with either ill-defined dots or traces of leak, at a stage soon after the swelling had reached the zenith. At stage soon after the swelling had subsided small dapples or dapples alone, or in combination with granule-shaped spots, dots or traces of leak appeared and its shadow was marked with dapples or large dapples 2 or 3 months after the attack of disease. The gland presented a nearly normal X-ray picture 6 months after the attack, indicating that a cure had been attained without any after-effects.抄録全体を表示PDF形式でダウンロード (2377K) -

ジャーナル フリーBy means of rotatory stimulation, a study on the vestibular respiratory change recorded electrically in normal human subjects and rabbits was performed.
Results obtained were as follows:
1. Exspiratory enlargement was observed by rotatory stimulation but was not observed by other stimulations except caloric stimulation while the nystagmus was observed. From above the author concludd that the exspiratory enlargement is a characteristic feature of vestibular origin.
2. According to the increase in the amount of rotatory stimulation, the vestibular respiratory change was shortened on latency, while on duration it was prolonged.
3. From the point of view of the autonomic nerve system, the respiratory change was plainly different on latency between sympaticotonic and parasympaticotonic conditions but these difference on duration could not be found.
4. The vestibular respiratory change appeared parallel with the vestibular function. When the hypofunction side was stimulated the duration was shorter than the normal-side-stimulation.
5. Nystagmus, turning sensation and respiratory change were recorded at the same time and significant differences were found 1) on latency between normal and latent autonomic unbalance, 2) on duration between those who have the tendency of moving sickness and those influenced by repeated rotatory stimulation.抄録全体を表示PDF形式でダウンロード (905K) -

ジャーナル フリーZenker's hypopharynx diverticles are relatively rare in Japan when compared to cases reported in Europe and America. A typical case of this disease with the diverticle larger than the size of a walnut was seen in a 56 years old house wife. Operation was done by one stage sac extirpation through left external neck incision and an uneventfull cure was attained after several endoscopic dilatations were performed.
Etiology on evolutionary and pathological factors, sex and age distribution, symptoms, findings, diagnosis and differential diagnosis, histology of sac, and finally various methods of treatment were discussed.
Surgical treatments at present are as follows;
1) Sectioning of the diverticle lip by endoscopy (German method).
2) Sectioning of the sphincter muscle of the so called“Schleudermuskel”(=Pars fundiformis of M. constrictor pharyngeus inf.) by way of lateral neck incision (German method).
3) One stage extirpation of sac body by way of lateral neck incision (English and American method).抄録全体を表示PDF形式でダウンロード (2698K) -

ジャーナル フリーThe influence of speech-stimulation upon spontaneous blinking was investigated with electreoculogram, and attempt was made to measure the hearing for speech by means of its application.
The following are the major findings;
1. In 40 cases (74.0%) out of 54 cases, which consisted of 30 cases with normal hearing and 24 cases with hard of hearing the inhibition or the facillitation of spontaneoos blinking was observed when speech stimulation was given.
Inhibition type was found in 33 cases (82.5%) and Facillitation type was found in 7 cases (17.5%).
2. Cases who shwed the difference of less than 0±12.5db between the threshold of the objective method (pure tone threshold, speech perception threshold, and speech discrimination threshold) were 80% in pure tone threshold, 92.3% in speech perception threshold and 84.6% in speech discrimiation threshold.
3. From these results, the abovementioned method is considered to have possibility in clinical application as one of the objective audiometries.抄録全体を表示PDF形式でダウンロード (569K)
