ジャーナル フリーThe auther studied comparatively the fine structure of bony otic capsule and otic sac varies in 28 different species of vertebrates including 3 amphibians, 3 reptiles, 3 birds, and 19 mammals with the measurement on the thickness of bony otic capsule and area of labyrinthine spaces.
I. Histological studies.
The conclusions were as follows:
I. Histological studies.
1) The bony otic capsule of vertebrates is composed of three layers of bone ; namely periostal, the intrachondrial combined withe the endochondral and the endosteal, but in amphibians and reptiles, middle layer was only partially observed.
2) In mammals and birds, the bony otic caps-ule is composed of compact bone, and its structure in the middle layer is so called lock of hair, but in reptiles and amphibians, its otic capsule is composed of fibrous tissue and the middle layer is mottled.
3) No significant histological difference was observed between grasseating and flesh-eating animals, as well as between land and quatic animals.
4) In lower animals, the bony otic capsule is not ossificated, but has the character of fibrous con-nective tissue. In reptiles and amphibians, cartila-gious tissue was observed. The cartilaginous inte-rglobural space shows remarkable difference according to the species of animals. It was found in almost all mammals except pipistrellus abramus and white rat, but could not be found in birds, reptiles and amphibians.
5) The blood vessel stretch is more significant for lower animals. It is especially significant in reptiles, amphibians, birds, and pipistrellus abramus, and osteoblasten was observed in reptiles and amphibians.
6) Bone cells are ripe in human species, and unripe in other animals.
7) The development of otic sac was roughly in proportion to that of bony otic capsules.
8) As to the property of bone cells and mat rative histology, that the bony otic capsule of human species is most complete.
II. Measurements.
1) The thickness of the bony otic capsule is roughly in proportion to the size of the skulls of animals.
2) The ratio of the total cross section area of the cochlear spaces to the size of the skull is larger for lower animals.
3) The boundary of each layer is distinct for the animals having thin middle layers, but not so distinct for most animals having thick middle layers.抄録全体を表示PDF形式でダウンロード (3279K) -

ジャーナル フリー1) Detailed history taking, routine otologic examination, audiometry and vestibular function tests were performed on 151 patients without vertigo who were hospitalized for periodic physical checkups and in 303 patients with vertigo. Two hundred and twenty of them also received blood pressure measurements and funduscopy as the tests for cerebral arteriosclerosis.
2) From the viewpoint of otological diagnosis, vertigo can be divided into three, Menieres disease in a narrow sense, Meniere's disease in a broad sense and "idiopathic vertigo". Vertigo of known cerebral causation such as brain tumor and other specific disorders was excluded from our present study.
3) Perceptive deafness and CP were common findings in Meniere's disease in a narrow sense, while CP was comparatively rare in the group of Meniere's disease in a broad sense. Both types of Meniere's disease, however, were sometimes accompanied with concomitant cerebral disorders.
4) Many cases of "idiopathic vertigo" showed DP, circulatory disturbance in the nystagmus system and the bilateral disturbance of the central nystagmus system associated with an appearance of fixation difficulty of eye ball in a high percentage and the prolongation of post-rotatoric nystagmus. These findings are known to be clear signs of arteriosclerosis; these facts indicating the importance of vestibular function tests for an early detection of cerebral arteriosclerosis.
5) The examination results were interpreted as abnormal in 15% in non-vertigo group and in 10% of 83 patients in whom cerebral arteriosclerosis was ruled out.
6) Pathology of vertigo can be more easily understood when an assumption is made that vertigo contains a reversible component of functional nature and an irreversible component due to organic disorders.抄録全体を表示PDF形式でダウンロード (910K) -

ジャーナル フリーDuring the year of 1959, the Better Hearing Clinic of Okayama University Medical School made a hearing survey of 29, 068 school children in Okayama City. The results revealed that 25 children had an average hearing loss of 45_??_60db in the better ear. They corresponded to 0.1% of all the primary school children in Okayama.
They were all suffering from sensory-neural lesions except one conductive. As the medical care did not seem to help them, some special education should be required for them.
For this accomplishment the special class for the hard of hearing was housed in the Uchisange Primary School, Okayama City. This was the first one established in Japan, which started with 9 pupils in April, 1960.
Children of the class have been educated among normal hearing children as possible, with the regular school curriculum, in order to secure enough to the normal social life. As to the special educational method, some subjects in the curriculums have been taught with the use of wireless group hearing aids in a specially designed silent classroom.抄録全体を表示PDF形式でダウンロード (1067K) -

ジャーナル フリーNineteen handicapped pupils, 15 of sensory-neural and 4 of mixed type hearing loss of 45_??_60db, were educated with the use of hearing aids, speechreading and visual educations for the past two years.
The results of the investigations are as follows:
1) Effects of hearing aids and speechreading. The use of hearing aids brought much better im provement of hearing discrimination in 12 pupils, fairly good in 5 and poor in 2. Combination of speechreading with hearing aids helped more to improve hearing discrimination.
2) Educational achievement. Nine pupils who had two years' education all showed considerable educational progress.
3) Results of speech correction. Seven of 19 pupils showed articulation disorders. Speech correction on them proved to be effective with the use of hearing aids.
4) Intelligence test. Mental ability of pupils were assessed by means of WISC test (modified for Japanese use). Pupils whose I.Q. were below 90, were reluctant to all the special educational procedures mentioned above.
Author concluded that the children who have both an average hearing loss 45--60db and the normal intelligence, should be eligible for the class for the hard of hearing.抄録全体を表示PDF形式でダウンロード (1004K) -

ジャーナル フリーThe authors observed on a case of a 21 year old male, who was found deaf when he was 3 year of age and was given a early speech therapy with hearing aid and lip reading.
1) By the pure tone audiometry his air conduction hearing was 81db in the left ear and was 86db in the right ear. Bone conduction were all scaled out.2) The results of articulation test in pronounciation were 84.3% and lip reading ability were 46% in case of help of the hearing aid and lip reading method, these results show twice as good percent as the deaf who was given the lip reading training only.
3) From these observations, the authors believe that the hearing aid is nessessary in the early speech therapy upon the congenital deaf child, regardless of the type and degree of the deafness.抄録全体を表示PDF形式でダウンロード (407K) -

ジャーナル フリーFor the purpose of investigating the change of the laryngoscopic finding in case of the vocal cord paralysis, the authors made the precise examinations of 15 cases, operated for the struma carcinomatosa, with the complication of the postoperative unilateral permanent vocal cord paralysis. In this series, operative findings of the injury grade, especially on the recurrent and superior laryngeal nerve at ions of the paralysed vocal cords had been observed for 2 years after the operation, with recording the electromyograph of the intrinsic laryngeal muscles. The following conclusions were obtained.
In the changes in positions of the paralysed vocal cords, two main currents were permitted : one, fixation in the median or paramedian position (40%), chiefly seen in the group without cutting of the recurrent laryngeal nerve and the other, transition from the median or paramedian position to the intermediate position (46.7%), chiefly seen in the group with cutting of that nerve.
(2) Summarizing the changes in positions of the paralysed vocal cords with the lapse of time after the operation, the median or paramedian position was assumed at first, and later the intermediate position. With the electromyographic investigations, this finding can be explained by gradual progress of the lowering of the function of the cricothyroid muscle, caused by the degeneration of the superior laryngeal nerve fibers due to the operative influences.
(3) From these investigations the complexity of the laryngeal function was again shown the necessity of the clarification of the conditions relating to the vocal cord paralysis was emphasized and new points for future studies were realized.抄録全体を表示PDF形式でダウンロード (1348K) -

ジャーナル フリー4. As regards the vestibular examination of the patients with acoustic tumor, spontaneous nystagmus was present in 21 (93%) of 23 cases, which were divided into 4 with horizontal direction-fixed nystagmus, 1 with vertical direction-fixed nystagmus, 14 with regular gaze-direction nystagmus, and 2 with irregular gaze-direction nystagmus.
No particular relationship between the nystagmus finding and the stage of development of the tumor could be found, and regular gaze-direction nystagmus was most frequent in any stage.
Positional nystagmus appeared in 12 (63%) of the examined 19 cases -Nylen's type I 6, type II 5. type III 1-, all of which, however, had already showed spontaneous nystagmus.
The result of caloric test was abnormal in 100 per cent of cases. They did not exhibit the response to irrigation with water of 30-C. for 40 seconds except in 2 cases within 6 months from their onset. This might indicate that there was the intimate relationship between the caloric hypo-excitability and the stage of developement.
The abnormal results of the past-pointing, stepping, Romberg, and blindfolded vertical writing test (Fukuda) were obtained in 94%, 90%, 72%, and 71, % respectively.
In addition, the blindfolded vertical test showed the different results depending on the side of the tumor, namely 58% in the cases with the left tumor and 89% in the right tumor.
Furthermore, the rate to be judged as cerebellar lesion was 69% in the past-pointing test, 73% in the blindfolded vertical writing test, 89% in the stepping test.
These values were nearly in accord with the rate of the gaze-direction nystagmus (74%) including the vertical spontaneous one in the nystagmus findings.抄録全体を表示PDF形式でダウンロード (559K) -
