JOURNAL FREE ACCESSThe authors reported a case of pinealoma of a 8 years old boy, who had an uneven form of bilateral hearing impairments, especially on the left side. At the time of autopsy, the degeneration of the corpus geniculatum mediale, bra- chium colliculi caudalis and lemniscus lateralis due to the presence of the tumor were revealed on the right side. These findings led us to the following conclusions: 1.This case has a type of midbrain deafness. 2.The crossed and the uncrossed central auditory pathways are almost equivalent with respect to auditory acuity. 3.The auditory pathways cross mainly through the trapezoid body.View full abstractDownload PDF (1181K) -

JOURNAL FREE ACCESSHearing acuity was measured in 164 normal children aged from 4 to 6 years by means of play-audiometry, and, at the same time, the mental capacity of these children was examined using Tanaka mental test for young children. Contrary to the author's presumption, no correlation was found between the hear- ing acuity and the mental capacity in these children examined.From this fact the conclusion was drawn that the improvement of average normal acuity of hearing in young children in response to the getting older was probably due to other factors than the development of their mental capacity.View full abstractDownload PDF (294K) -

JOURNAL FREE ACCESSThe following study has been made for how long inner ear cells survive after the decapitation. The cochlea of decapitated guinea pig was taken out and, after definite hours, was inserted into suitable environments such as cisterna magna, camera oculi, cavum abdo- minalis and nape-muscle of living guinea pig, where it was preserved for certain hours, , and then the morphological changes 6 hours after the death of the animal was in- spected. It was generally observed that the group, that was inserted into the suitable environments earlier, showed the changes the later, compared with the control group which was preserved in normal saline at 37- C for 6 hours wrapping with the retarda- tion of the postmortem changes indicate the survival of the cells when they were in- serted into the above mentioned suitable environments. A considerable number of spiral ganglion cells are able to survive for 3 hours spiral limbus cells almost for 4∼5 hours, and Deiters's cells, Hensen's cells, stria vas- cularis and Reissner's membrane for 3∼4 hours after decapitation of the animal.The other cells survive indefinitely.View full abstractDownload PDF (2138K) -

JOURNAL FREE ACCESSA study was made on the cochlear response (CR) in guinea pigs with experimen- tally developed Meniere's disease.The disease developed following intracranial admi- nistration of pilocarpin and acetylcholine around the eighth nerve unilaterally.The development of the disease was confirmed clinically by the ocular symptoms of nystag- mus and deviation, and histopathologically by labyrinthine hydrops. The results obtained in these experiments were as follows : 1.The ocular symptoms appeared about 2 minutes after administration of acetylc holine.Suggesting an excitation on the affected side, CR began to diminish 15∼30 minutes after administration.CR reduced to the lowest (15∼20 db) 2∼3 hours after administration.The higher the frequency the more the reduction.A slight but steady recovery (5db) from the lowest CR appeared 4 hours after administration.After CR was studied, the treated inner ear was examined revealy a slight hydropic changes his- topathologically (convex Reisner's membrane, compression of tectoria and vascular dila- tation). 2.By the administration of pilocarpin, an excitation of the labyrinth, reduction and subsequent recovery of CR, and hydropic changes were observed. 3.The administration of adrenaline was followed by disturbed function of the labyrinth, showing no recovery of reduced CR.Histopathological examination showed collapse labyrinthi (concave Reisner's membrane and decompression of the tectoria).View full abstractDownload PDF (2071K) -

JOURNAL FREE ACCESSHypertrophy of the adenoid tissue in the naso-pharynx is closely connected with the disorders of the ear and nose, and it is necessary to estimate the size of adenoid tissue prior to the treatment of these disorders.In children, however, it is sometimes difficult to measure the accurate size of adenoid tissue. Authors studied the measurement of the size by X-ray. The conditions of radiography were as follows ;
1)Tube voltage ......................................................140 kVp
2)Tube current ......................................................2∼3 mAsec
3)Exposure time ...................................................0.1∼0.2 sec.
4)Size of the focus...................................................1.5x1.5mm
On the lateral X-ray film of the head obtained with above mentioned conditions, we could clearly trace the figure of the adenoid tissue (See picture No.1 and 2).View full abstractDownload PDF (494K) -
PHYSIOPATHOLOGICAL STUDIES ON ATROPHIC RHINITIS IN VIEWPOINT OF AIR TEMPERATURE IN RESPIRATORY TRACTS. NAKAGAWA1957 Volume 60 Issue 10 Pages 1398-1407

JOURNAL FREE ACCESSTemperature change of the air in human and animal respiratory tracts was recoded and measured by thermocouple, special vibrator and oscillograph. Passing through the respiratory tract, the temperature of inspired air continuously rises, while that of expired gradually falls.In cases of atrophic rhinitis, both the rise and the fall of temperature of the air passing through the nose are not so remarkable as in normal subjects.After Kubo's maxilloturbinal plastic surgery, temperature change of the ais returns to that of normal subjects.With this in mind, the author discussed the dryness of the mucous membrane of respiratory tract of atrophic rhinitis on the concept of humidity of the air inspired and expired.View full abstractDownload PDF (3558K) -

JOURNAL FREE ACCESSThe author classified tinnitus audiographically in the preceding report as follows, 1)non-deafness tinnjtus, 2)conductive tinnitus, 3)perceptive tinnitus etc. Under this classification the author studied the clinical characteristics of each type of tinnitus on 236 cases and obtained the followingresults. 1)All tinnitus, which were biaural, initiated mostly at the same time. 2)Most of perceptive tinnitus were continuous, stabile and irreversible, but con- ductive tinnitus was reversible and labile. 3)The tone of perceptive tinnitus was mainly of high pitch, but that of the con- ductive tinnitus was of low pitch. 4)The loudness of tinnltus was hardly changeble and the tone also stayed in the same character through its whole course. 5)The humming tone was most frequently noted in all types of tinnitus, especially in the perceptive tinnitus. 6)Tinnitus, either conductive or perceptive, beczme louder with the progress of fatigue and in the quiet room. 7)The biaural tinnitus was always seen in the case which had the same type of pnumatization on both sides. These findings suggest that tinnitus might have some relationship with the local anatomical structure of the ear.View full abstractDownload PDF (1124K) -

JOURNAL FREE ACCESSThe author made a follow-up study on the effect of the following treatment for tinnitus cf all types which he had classified by audiography. 1)The study was carried out on 236 cases, 303 ears and the following geeral re- suits were obtained. Tinnitus disappeared in 29ears, and decreased in 78 ears. 2)Canductive tinnitus proved the high sensitivity to all treatments employed, but perceptive tinnitus was not affected by any treatment. 3)The vaso-dilating agents were effectlve for conductive tinnitus, but were not so effctive for perceptive tinnitus. 4)The intravenous administration of Vitamin Bl in high dosage was effective for perceptive tinnitus. 5)The blockade of the ptergopalatine ganglion by Novocain was effetive for tin- nitus of perceptive type. 6)The air inflation and massage of ear drum were effctive for conductive tinnitus. 7)In order to evaluate the effect of the treatments for tinnitus he devised a audi- ogrophy technique of tinnitus which consisted of the masking level of tinnitus masked by pure tone, and he confirmed that the fluctuation of this tinnitus audiography pre- rented the change of loudness of tinnitus.View full abstractDownload PDF (759K) -

JOURNAL FREE ACCESSThe author masked tinnitus by pura tone and established fous types of tinnitus au- d'ograms. The tinnitus audiogram which recorded the relationship between the threshold curve of air conduction hearing and the masking curve of tinnitus showed the characteristics of tinnitus most distinctly. Curve A represents the threshold curve of airconduction and curveB, the masking curve of tinnitus. Between these types of tinnitus audiogram and the types of tinnitus classified by author according to the audiography, there were following relationships. 1)Parallel-horizontal form(Curve A and curve B run almost parallel with zero level of normal hearing)was found frequently in conductive tinnitus. 2)Parallel form(Curve A and curve Brun almost parallel, but decline in the high tone zone)was seen frequently in percep tivetinnitus. 3)High-tone convergence form(Curve A and curve B converge in the high tone zone)was seen ferquently in non-deafness tinnitus. 4)High-tone divergence form(Curve A and curve B diverge in the zone of high tone)was seen frequently in perceptive tinnitus. 5)Low-tone convergence form(Curve A and curve B converge in the low tone zone)was seen frequently in non-deafness tinnitus and conductive tinnitus. 6)lrregular form(No definite relationship between curve A and curve B)was seen frequently in perceptive tinnitus.View full abstractDownload PDF (895K) -

JOURNAL FREE ACCESSGuinea pigs were exposed to X-rayirradiation, three droses of 600r and 4 doses of 400r.which developed no histopathological changes in auditory organs, and then aco- ustic stimuli were given. The acoustic stimuli given were 110 phon pure tone at 2000cps, 2 hours daily for 10consecutive days.It had been confirmed that the acoustic stimuli developed no pa- thological changes of the auditory organs, of healthy animals. The results obtained were as follows 1.The animals, general condition was poor.Preyer's reflex decreased above 2000 cps. 2.The hematologic study showed the signs of panmyelophthisis and remarkable leucopenia. 3.When the animals irradia'ed with X-ray were exposed to acoust'c trauma, re- markable atrophic degeneration was observed in Corti's organ localize in the 2nd turn. It was concluded that guinea pigs treated with X-ray irradiation had increased susceptibility to acoustic trauma.View full abstractDownload PDF (3256K) -

JOURNAL FREE ACCESSOn the basis of the fact that the diameter of the monoaural skin-projection is pro- portional to the intensity of the tone perceived, the process of restoration from the au- ditory fatigue immediately after 5 minuites exposure to 65 db of pure tones or white noise was measured.The test-tone, identical or half octave higher pare tones or white noise of 30 db, was introduced instantaneously after taking off the exposure-tone and the gradual growth of the edge of the skin-projection in consequence of the restoration from the fatigue was continuously traced by the chymography. In the course of the restoration from the fatigue, 2 stages at the beginning quicker and then slower were found.And at the beginning, hearing loss was 20 db or more even at the exposure to the intensity of 65 db.The restoration in the case of higher tones was prolonged compared with that of lower tones or white noise, and less fatigue was observed at the exposure to the half octave lower tones.View full abstractDownload PDF (473K) -

JOURNAL FREE ACCESSIn the previous report a new method of determining potassium concentration in the ultra minute volume of endolymph obtained from an inner ear of the guinea pig was reported.The volume 0.0001 to 0.001 cc of the endolymph was determined accurately by a comparator, then the sample was diluted to 5 cc with by the distilled water, and its potassium concentration was determined by a flame spectrophotometer. Various samples of the known potassium concentration of 150, 100 and 70 mEq/1 were tested by this method and the experimental error was found to be as accurate as under ± 5 % (the first report). Applying this method to ten samples of the endolymph obtained from one inner ear of normal guinea pigs were examined.Their potassium concentration ranged from 122 to 166 mEq/1.View full abstractDownload PDF (257K) -
