ジャーナル フリーThe tissue culture of mammalian (human embryos and new born kittens) membranous labyrinths were performed under the roller tube method with the object of observing the labyrinth epithels in their living state, and to determine the correlationbetween the structure and nutritional transportation in Corti's organ. Since the materials used were obtained from human embryos and new born kittens, a need to recognize preliminary the stepwise development of this organ under conventional histological specimens from the standpoint of embryology was found. Comparison of the structures in vivo and behaviors of these epithelial cells in vitro, led the author to conclude the followings results.
1) The inner hair cells appeared in outgrowing zone on the 11 th. day in vitro from the human fetus labyrinth (C.R 65 mm).
2) Relatively long term cultivation of C-R 100mm human fetuses revealed the labyrinth epithels appearing in tubular structures on the glass surface, which consisted of hair cells and tectorial membranes.
3) Sudanophile substances could be seen in cytoplasma of involuting cells outgrowing from explanted Corti's organ in its every developmental stages.
4) Emigrating epithelial cells from the explant of Corti's organ of new born kitten, flattened out diffusely on the glass surface. Some of them showed their intrinsic structures. Among them there could be seen the commonly called haired cells.They had conspicuously, two kinds of hair structure on their free surface, one was kinocilia and the other, stereocilia.
5) Abundant of granules were found in the epithels of new born kitten's stria vascularis.抄録全体を表示PDF形式でダウンロード (6332K) -

ジャーナル フリーPneumatization of the temporal bones in 34 cases, 40 ears was carried out and their horizontal sections were made.
Dimenssions of the epitympanums and auditory ossicles in the border of the epitympanum and mesotympanum by the planimeter, were then taken and on estimation of the ratio of both dimenssions were made.
Furthermore, abnormal posstion or adhesion between epitympanum and auditory ossicle were also observed.
The results are as followes.
1) High correlation between dimensions of the horizontal-sected epitympanums and pneumatization of the temporal bones was seen.
Namely, the more stronger the pneumatizations of the temporal bones, the more their dimenssions are wide, while the more repressed, the more nar- rowed.
2) Individual difference, in the dimenssion of the horizontal-sected auditory ossicle, has been re-cognized, but the correlation between the former and pneumatizations of the temporal bones were not seen.
3) The ratio of both dimenssions had high correlation to the pneumatization of the temporal bone.Namely, the better pneumatization of the tem-poral bones, the more the space between epitympa-num and auditory ossicle are wide, while on the contrary the more repressed, the more narrowed.
4) In one out of 40 cases, the epitympanum was so markedly cellulated that a top of the cellulle-process was closed to the malleus and the short process of incus was attached to the bone wall.
In this case, pneumatization of the temporal bone is the best.
From results of 4) and our clinic experience, the author found the existence of the new type of the pseudo-otosclerosis.
From these results author has the opinion that, the temporal bones of repressed pneumatisation are apt to be closed the space between the epitympanum and auditory ossicle more often than the well pne-umatized ones beeing caused by the pathological changes.Furthermore, the cause of epitympanal cholest-eatoma was also discussed.
Author has the opinion from good cases results of 1), 2), and 3), that compared to relatively the cases of repressed pneumatization the temporal bone where closed space between the epitympanum and auditory ossicle was seen was caused by the patho-logical changes.
Furthermore, the cause of epitympanal cholest-eatoma was also discussed.抄録全体を表示PDF形式でダウンロード (3001K) -

ジャーナル フリーThe authors reported 11 cases of labyrinthine syphilis, the clinical picture of them was suggestive of Meniere's syndrome. Among them, 6 cases were considered as congenital and 5 cases as aquired syphilis. Serological reactions of syphilis were positive in all cases.
8 cases had the histories of syphilitic ocular fness of moderate or severe degree (average hearing loss in the middle tone reange was 35 to 65db). Spontaneous nystagmus of peripheral type were rmal and rotatoacceleratory stimuli were decreased bilateraly.
In 8 cases with repeated paroxysmal rotatory ped irreversibly at every attack. In 3 cases without rotatory vertigo, however, showed chronic ataxia and unsteadiness and these symptoms gradually improved during the course of several months. general therapeutic methods of Meniere's syndrome were also performed. Among them, xylocaine blocking of the stellate ganglion, injection of large use of bellergal were relatively effective. lations between thess cases and Meniers's disease were discussed.
In conclusion, the authors emphasized, when a otologist meets with such case of Meniers's syndrome of irregular irreversible type, he must give his mind to labyrinthine syphilis and carry out the specific serological examination.抄録全体を表示PDF形式でダウンロード (1005K) -

ジャーナル フリーIn cases where stapes at the oval window could not be found, Wullstei type IV tympanoplasty has been performed, but this method does not always give the best surgical results. Recently many operative procedures using polyethylene tube as a columella, in order to change type IV into type III, are reported. However, the author has found the autotransplantation of ossicle as a columella more preferable way than using foreign bodies.
The authror's method is as follows : ossicle as a columella is fixed upright to the skin graft with fine thread and the other end of this ossicle is placed at the oval window. Seven such operations have been experienced. In 5, malleus was used, in another case, incus and in the last, ossicle made from mastoid bone tip into adequete shape was used.
Results of these operations : One case did not show any hearing improvement, but this was believed to be a good result because his hearing loss was at the same level, 25db, before and after operation. Other 6 cases showed improvement of more than 20db, 5 cases among 7 kept a better than 30db post-operative hearing acuity, and all cases better than 35db. None of them has shown perforation of transplanted tympanic membrane and ear discharge up to date.抄録全体を表示PDF形式でダウンロード (1195K) -

ジャーナル フリーIn order to demonstrate minute changes in the cardiac function due to surgical procedure of head and neck, ECGs were taken from 85 patients with chronic tonsillitis before and immediately after Tonsillectomy.
Changes of ECG demonstrated in the present study were explained from Reilly's phenomenon, ulation applied on the autonomic Nervous system.
The results were summarized as follows :
(1) Abnormal ECG findings were seen in 9.4% of these patients preoperatively.
(2) The most notable changes of ECG before more than 70% of cases after local anesthesia and immediately after tonsillectomy.
(3) The Author concluded that these are the porary coronary insufficiency as a result of tonsillar irritation. (4)From findings obtained after injecting various kind of anesthetics into the paratonsillar area, it was concluded that these Autonomic nerve stimulation was not caused by toxic reaction of the substance injected, but rather mechanical irritation itself was found to be the main factor.This also applies to the surgical stimulation. (5)The occurence of ECG changes could not be prevented by the use of chlorpromazine, but the use of General anesthesia which maintained the third stage of anesthesia during the procedure could suppress the ECG changes. (6)Similar ECG changes were seen in 39.3% ery besides tonsillectomy.抄録全体を表示PDF形式でダウンロード (2676K) -

ジャーナル フリーThe writer has completed a new photo-cinebronchoscope by applying a different illumination method, that is, by using Xenon are lamp as a light source. This illumination method may be called a out of the light source is converged into the coniform flux which is projected at a certain angle through an achromatic lens. This flux is reflected into the bronchoscope by a plane mirror with an elliptic hole in the center. The elliptic hole is quite similar in size and shape to the inside diameter of a bronchoscope when it is viewed from the back.
The flux reflected into the bronchoscope in this choscope, focusing and then diverging. Thus, homogeneous illumination can be secured at the tip of the bronchoscope. The position of focus can be easily adjusted in proportion to the distance to the object by moving the achromatic lens. In order to absorb ultraviolet rays and infrared rays, two filters are fixed in the lens box. Flux direction can be adjusted by two reciprocally revolving prisms. The brightness produced by this apparatus at the tip of sured directly is 50, 000 lux, with no thermal effect.
An air curtain is made by getting the hot air used for the forced air cooling of Xenon arc lamp to blow out behind the plane reflex mirror. The air curtain thus made is useful in preventing the lens from blurring and spoiling by expirated sputum. sible. Bolex H16 Reflex is therefore employed for a 16mm movie, and a 150mm telephoto lens extended by an extension tube is used in photographing. An Asahi Pentax camera was used to take still pictures, with the aid of a 135mm telephoto lens with an extension tube.
In conclusion, "Yoshida's Flux Crossing Method" is ideal for illumination of slender objects. The distinct feature of his new idea is that flux cross themselves, then focusing and diverging. The writer tographing not only bronchi but also ears, larynx and in other fields of medicine and that it is also useful in the engineering field.抄録全体を表示PDF形式でダウンロード (6754K)
