JOURNAL FREE ACCESSThe authors have studied how accurately 30 young women can repeat a tone or can sing the musical tone from c' to c". They repeated a tone of c' more correctly when it was produced by piano than a tone produced by a tuning fork. After the examinees heard a tone of c' from a piano or a tuning fork, 70% of them could sing the musical scale of tone above the tone of c' with error of ±2% of each tone. It is known that to sing the musical scale after the first tone of c' is given is more difficult than to repeat the tone.
When the examinees tried to repeat a halfpitched tone such as f' above e' or c" above b', they tended to repeat f' or c" lower than each accurate frequency.View full abstractDownload PDF (1398K) -

JOURNAL FREE ACCESSSince the past study it has been stated that different hearing effects occured whether the sound stimuli were given from a distant loudspeaker or a telephone receiver. This phenomenon will be explained from the different effective impedance of the ear, which is altered by the outer orifice of the meatus opened or not.
And when there is a perforation on the drum membrane, the alteration of the impedance of the sound transmission system is added, and this will make the effect of the sound stimulus more remarkably.
Upon these considerations, the model ear experiment, the animal experiment and the clinical hearing tests were pursued.
The results are summarized as follows:
(1) Both the minimum audible thresholds measured by the receiver method (a coupler method) and the speaker method (a free field method), showed some more reduction for the low tones below 1, 000cps. by the perforated drum membrane than by the none-perforated one, and an about 10_??_15db more loss existed by the receiver method than by the speaker method.
(2) The difference between two methods was considered as due to the acoustical leakage according to the perforation of the drum membrane.
(3) Therefore, when we considered the true hearing of a patient with a perforated drum membrane, the result of the hearing test with the telephone receiver must reduced be some db, especially in the range of low tones.
(4) There was scarcely found any difference in the audiograms between the two methods, if there was no perforation. But it was suggested that some indirect bone conduction might exist at the severe conductive deafness.
(5) The above results were affirmed also by some theoretical considerations.View full abstractDownload PDF (6831K) -

JOURNAL FREE ACCESSObservation was made on the 17 cases who have received gradual ligation of the carotid artery for radical neck dissection of tumor, adhered with the common artery.
1) The vessel was ligated loosly at first to make its lumen one half of the previous size and four days later complete ligation would be performed and after 3 days the common carotid artery was removed with tumor.
2) Extripation of the carotid artery with tumor were performed on 10 cases and ligation alone were performed on 7 cases.
3) Complications due to ligation of the carotid artery were 4 hemiplegia, 3 mental confusion, 4 unconciousness, 7 severe hadache and 3 Horner's synmptome.
4) 3 died cases were seemed to be caused by ligation.
5) The cause of death of these 3 cases was as follows one died of emaciation, the second died of neurological complication and the third died of hemorrage of the ligated carotid artery.
6) Regard to prognosis, died cases were 12 who have died within one year after the ligation and survived cases were 5. One of 5 survived cases has lived 4 years after the ligation.
7) E.E.G. test was performed on 6cases. One of 6 cases gave the 2 wave depression on F-P leed and this case died 6 days later of neurological deficit.
8) Cerebral angiogrphy was performed on 5 cases. Collateral circulation was confirmed on the cases of 20 days after ligation.
9) 6 cases received the 90 second unilateral liga- tion of carotid artery and Po2 was examined on the blood of the homolateral jugular vein. One case demonstrated the 23% decrease and hemiplegia. 5 cases recovered from the decrease to the average level of Pot of blood of homolateral jugu- lar vein at one week after complete ligation.View full abstractDownload PDF (910K) -

JOURNAL FREE ACCESSThe author reported on the results of the 0KP test in 474 cases of vestibulo-oculomotor dysfunction. Some cases of the lesions in the CNS were verified by surgical operation and autopsy. In some cases of the peripheral vestibular lesions, diagnosis was given by precise neurological examinations.
1. OKP test is a examination for the pure oculomotor function and the test reveals typical pattern in the CNS lesions. The test plays an important role for the diagnosis of the lesion in the tegmentum of the brain stem i.e. so called "Silent area"
2. OKP in the peripheral vestibular disorder reveals typical pattern and is usefull for the deection of the side of the lesion as well.
3. Further OKP test is a usefull tool not only for the observation of the recovery process of the vestibular imbalance, central compensatory process and the evaluation of the postoperative relapse of the brain tumor, but also usefull for the differential diagnosis of nystagmus and for the evaluation of the dynamic oculomotor disturbances.
Special attention should be paid on the result of the examination to eliminate the diseases of the eye ball itself and the accessory apparatus of the eye ball. Age, state of the alertness interfare the result occasionally, so that the examination should be carried out under "interested gaze.'View full abstractDownload PDF (2752K) -

JOURNAL FREE ACCESSAuthors considered about the closure of the tympanic membrane that was attempted by many former otologist. And authors described our myringoplasty which was done by endoaural method.
The results are as follows :
1) 18 cases of 20 cases have been repaired by authors' method.
2) Authors failed in two cases. The failure caused due to poor technique in one and due to infection in another.
3) On an average, the pstoperative hearing improvement at the speech frequencies range was 10.9db as compared with the preoperative hearing.View full abstractDownload PDF (2279K) -

JOURNAL FREE ACCESSThree cases of the right anomalous subclavian artery were detected out of the 316 patients received the radiological examinations of the esophagus in our clinic.
Case 1 : A 59 years old woman complained of dysphagia and recurrent vomitting for six months. The right axillary artery was surgically punctured and a radiolopaque catheter was inserted into the artery under fluoroscopic control. From this method the aberrant right subclavian artery and its aneurysmal dilatation were confirmed.
Case 2: A 31-year-old female suffered from dysphagia for three months. By the radiological examination and the direct esophagoscope the arteria lusoria with chronic esophagitis was proved.
Case 3: A 42 years old woman complained no dysphagia. The arteria lusoria was found by the radiological examination of the esophagus.
According to our experiences, the catheterization is considered one of the most excellent methods for the detection of this anomaly.View full abstractDownload PDF (1689K) -

JOURNAL FREE ACCESSA case of malignant melanoma with wide hematogenic metastases was reported. The primary lesion was a pigmented tumor in the nasal cavity, originating from lower nasal turbinate, with repeated nasal bleeding.
It was revealed by autopsy that there were two types of metastasis in malignant melanoma, one was melanotic type, with melanin pigment, and the other was amelanotic, without melanin pigment. Although these two types might be observed in the same organ, these were clearly separated to each other. Namely, two types were clearly differentiated and these were no evidence of transition of both types.
The change observed in melanocyte; melanotic to amelanotic, might be influenced by radiation therapy in this paticular case.View full abstractDownload PDF (1378K) -

JOURNAL FREE ACCESSIn order to diagnose the patients suffering from vertigo due to Meniere's disease, otologists generally examine the otologic functions and usually find some disturbances in the cochlear and vestibular labyrinths. But the author believes that they are incomplete.
Otologists have to find the etiologic factors in the whole body which cause the dysfunction of the periphery labyrinth i.e. circulatory, autonomic, central nervous or metabolic disorders.
From this standpoint, the author investigated 90 cases of labyrinthine vertigo not only by the audiometric and vestibular examinations but by the examination of the circulatory system and ob- tained following results.
1. Out of 90 cases of labyrinthine vertigo w- hich blood pressure examined, hypotension in 34, positional hypotension in 16 and hypertension in 3 were obtained. The rest 38 showed normal tension. It is of importance to have found that 16 cases which showed positional hypotension were all suffering from Meniere's disease.
2. Out of 12 cases of positional hypotension, 9 showed marked imbalance (deviation) in the vestibulospinal system, by the blindfolded vertical writing test as well as by the stepping test, simu- ltaneously with the down of blood pressure due to the change of body position.
3. After the administration of carnigen to 12 cases of positional hypotension, 8 showed marked improvement of vertigo not only subjectively but objectively by the tests above described.
4. The histories of patients pointed out fol- lowing facts;
1) The subjective sensation of vertigo was not always fixed but changed in the course of the disease. For example, the rotatory vertigo (Dre- hschwindel) changed to dizziness (Schwankschwi- ndel) and vice versa,
2) The initial attack was experienced by many patients in the night or morning when he changed the body position in bed or he got up out of bed.
3) Before the initial attack, many patients were pointed out of each unusual blood pressure.View full abstractDownload PDF (5524K) -

JOURNAL FREE ACCESSAs one of the approaches to study the prevention of noise trauma, it is important to determine the noise susceptibility of the individual. It is a fact that there are individual differences in the susceptibility of the auditory organs to noise sti- mulus. In order to devise a method of predicting this noise susceptibility, an investigation was made into the temporary auditory fatigue after noise stimulation and the recovery pattern from it.
The results obtained were as follows:
1) The temporary threshold shift (T.T.S.) following the stimulation with white noise for one minute shows a sharp rise when the stimulus noi- se pressure reaches 85 to 90db (SL).
2) The bounce seen in the recovery process of audition is most apt to be detected with the stimulus noise at 4000to 5000cps for I to 2 minu- tes.
3) The bounce appears at 85db (SL) of the stimulus noise pressure, reaches its maximum at 90db (SL), and almost disappears at 100db (SL).
4) Low-cycled tinnitus and recruitment begin to appear at 90db (SL) of the stimulus noise pressure.
5) From the initial stimulus noise pressure to induce bounce, viewed in relation to T.T.S., tinnitus and recruitment, the critical intensity of noise was estimated and a method of predicting the noise susceptibility.View full abstractDownload PDF (3140K) -

JOURNAL FREE ACCESSThe phonatory function of the larynx and its disturbance were discussed on the basis of the author's data of 1) electromyographical observation of the human larynx, 2) radiographical study of the larynx, 3) measurement of the mean subglottal air pressure as well as the vibratory subglottal pressure variation during phonation, and 4) analysis of vocal cord movements during phonation with high speed cinematography.
Chief findings are as follows:
1) In cases of recurrent laryngeal nerve paralysis, each electrical activity of the laryngeal muscles appeared in 4 different patterns, i.e. i) silent, ii) fibrillation voltage, iii) complex NMU voltage, iv) normal NMU voltage in compliance with the duration of the paralysis. Even when the normal NMU voltage was observed, the phenomenon of the misdirected regeneration of the paralysed nerve fibers was found in many cases.
2) In cases of unilateral recurrent laryngeal nerve paralysis, the paralysed vocal cord was usually thinner and situated lower than the healthy one. The shape of the subglottic cavity during phonation was rather spheric in the healthy side while it was parabolic in the paralysed side.
3) The subglottal air pressure varied synchronously with the pitch of the voice. The air pressure ascended during the closed phase of the glottis and descended during the opened phase. The mean subglottal pressure was higher in the diseased larynx such as laryngeal carcinoma and recurrent laryngeal nerve paralysis than in the normal one.
4) The vibration of the vocal cords was accompanied by the wave-like movement of the mucous membrane. When the larynx was affected the wave like motion first diminished and disappeared: for example, in the blowing experiment with the excised larynx, when the mucosa was dry the wave like motion disappeared and then the vibration of the vocal cords ceased. The author has put forward the mucoviscoelastic-aerodynamic theory pertaining to vocal cord vibration.View full abstractDownload PDF (1612K)
