    The present study was designed to investigate the shift of the auditory threshold of rabbits in the presence of another pure tone by means of cortical auditory response.
    Nine waking rabbits were used in this experiment.
    A pure tone of 1000cps at nine intensity levels, 0, 30, 40, 50, 60, 70, 80, 90 and 100db, was used as the first tone, while pure tones of five frequencies, 350, 700, 1400, 2800 and 5600cps were selected as the second tone. The first tone was accompanied by the second tone at an interval of 5-6sec. The threshold of the second tone was determined by the superimposing technique.
    The randomized block design of the inductive statistics was applied to make negligible the individual differences of experimental animals and to equalize the field of experiment.
    The results obtained were as follows:
    (1) With the increasing in the intensity of the first tone, the threshold of the cortical auditory response was elevated.
    (2) The amount of the threshold shift varied with the frequencies close to that of the first tone (1000cps).
    (3) The relationship between the mean value of the thresholds and the intensity of the first tone of 30 to 100db could be represented statistically with a straight line.
    (4) Auditory threshold of rabbits was considered to be less than 30db at 1000cps, since an evident effect on the auditory threshold was already observed with first tone at the intensity level of 30db.

    1) On histopathological findings.
    The mucous membrane about the pharyngeal orifice of the Eustachian tube bears, for the most part, the pseudostratified, ciliated columnar eptihelium. On the other hand the stratified squamous epithelium appears on the lower portion of the torus tubarius.
    The pseudostratified, ciliated columnar epithelium shows, in all case (14 cases), proliferation and metaplasia to the stratified squamous. Degeneration of the epithelial cells is found in 4 cases, and blackbrown pigmentation within the epithelial cells in 2 cases. The marked falling out of the epithelium is observed in 8 cases, most of which may occur by mechanical stress when collected, but some of them show apparently the sign of inflammatory reaction. Cilia is agglutinated broadly and its direction is irregular. Large number of the goblet cells are observed in every cases and they are more prevalent in number on the torus tubarius than in other portions.
    The developement of the mixed glands varies considerably in different portions of the mucous membrane. In general, the glands are better developed on the torus tubarius and decrease in number near the roof of the nasopharynx and on the anterior torus (plica salpingopalatina). Atrophia and degeneration of the glandular cells, and the dilated acini are observed in 2 cases each. The fibrosis around the glandular acini is promtinen in half of the cases. The cyst-formation of the ducts of the glands is found in most cases. Generally, the small round cell infiltration is accentuated around the ducts. One of the interesting findings is the appearence of oncocytes in 11 cases.
    The formation of the lymphoid nodules varies in different portions of the mucous membrane. It is found in half of the cases on the torus tubarius, though it is rare about the orifice of the Eustachian tube and on the anterior torus. On the other hand, there are 5 cases in which it cannot be found at all. The lymphatic tissue about the pharyngeal orifice of the Eustachian tube is apparently independent of that of the nasopharynx, especially of the Rosenmuller's fossa.
    The remarkable fibrosis is found in the lamina propria in 11 cases. Separated from the main cartilage, several pieces of the accessory cartilage are observed.
    Although the most cases, collected at random, are considerably from the aged, the certain inflammatory changes are found in every cases. Therefore it is emphasized that the histopathological changes to some extent may be present physiologically in the mucous membrane of the nasopharynx where receives the stimulations from outside most frequently.

    The author followed up, in a questionaire survey, the development of speech in 51 children who had consulted our clinic during the period of June 1950 through August 1955 with the complaint of retarded onset or development of speech. According to the initial diagnosis, 34 out of total 51 children were determined to be resulted from deafness and 4 from mental deficiency. On the other hand, 12 children were considered to have a good prognosis as they showed neither hearing disorders nor mental deficiency. Contrary to the author's expectation, however, the subsequent. development of speech in these 12 children was found to be far from satisfactory, normal speech being so far achieved in only 3 children.

    Mental development of children with speech or hearing disorders cannot be mesured with routine testing procedure since they cannot hear or answer the questions in the tests. Non-verbal tests are of necessity for these children. According to Barr, 40 non-verbal testing series have already been reported in Europe and America.
    On the basis of Ushijima's tests of mental development, the author contrived a non-verbal testing series for measuring mental growth of children with communication disorders. The procedures and the standardization of the test were described in detail.

    1) The author attempted the audiometry on the examinees from 3 month old infants to adults by using the cochleo-pupillar response during sleep. As soporific, mintal (3-5mg/kg injected in muscles) was used in almost all the cases.
    2) The cochleo-pupillar responses appear most distinctly when the examinees' sleep is very light and also immediately after they fell into sleep.
    3) On the ears of normal hearing, 82.5% of them response at 40-70db. No age differences are found on the threshold of the response (it is, however, much easier to decide the threshold of infants than of the older examinees).
    4) In the case of conductive deafness the response is evoked at the average intensity level of 47.0db above threshold, and in the case of perceptive deafness at 22.8db. This marked difference in the threshold values between the both types of deafness implies in the fact that the method can be used to decide whether the hearing difficulty lies in conduction or perception.
    5) The response is considered to be elicited through the auditory pathway even if the sound stimulus is so intensive that it is accompanied with tactile sensation.
    6) The response can be used as an objective method of hearing test on the infant baby as well as on the children of mental weakness. It is also useful as a method for detecting and diagnosing the hearing difficulty of central origin.

    In an attempt to simplify rotatory pattern test as a vestibular function test, we devised a revolving chair, rotated by hand, which was first accelerated by a spring and then gradually decelerated (decreased the angular velocity) until its spontaneous cessation of rotation.
    As a preliminary step, 26 normal persons were tested on the chair.
    Consequently, the duration of nystagmus observed after spontaneous cessation of rotation showed, regardless of the direction of rotation, linear relation with logarithm of the intensity of stimulation i.e. the angular deflection, with which the chair had been first set.
    It seems to be probable that each of the labyrinthine and other related disorders may show a more or less characteristic pattern in comparison with the normal accelodecelogram.

    To clarify the mechanism of “Heilanaesthesie” (Huneke, 1925), modified procedures were performed on 100 patients with various diseases. The patients were divided into two groups. In the first group, 1.0ml of physiologic saline was injected into both sides of the soft palate submucosa near the tonsils. Those in the second group were injected with 0.5% procaine solution in the same manner.
    The results of these procedures were 84 patients completely to partially cured, 14 unchanged, and 2 with progression of their disease. There was no difference in effectiveness of the saline and procaine.
    From this study the following conclusions were made:
    1. The healing mechanism of “Heilanaesthesie” is unrelated to the action of local anaesthetics, contrary to former reports, and is thought to be nonspecific stimulation to the neurovascular system rather than blocking of nerves.
    2. Because there is no direct connection in innervation of the injected area and remote lesions. the effect resembles Reilly's phenomenon. If the given stimulus is strong the reaction may be expessed as Reilly's phenomenon, and if weak may produce the healing effects as “Heilanaesthesie”
    The authors are of the opinion that the diagnostic value of the “Heilanaesthesie” and of tonsillectomy as a cancellation-based diagnosis of focal infection may be doubtful.

    The cases of congenital malformation of the middle ear have often been reported, but the condition limited to the stapes alone as presented in this paper, seems to be rare in literature.
    The patient was a girl of 13 years old whose chief complaint was hard of hearing. No abnormal finding was seen on otoscopic examination, but functional examination revealed the impairment of hearing which might be attributable to congenital stapes fixation or otosclerosis. On exploring the middle ear cavity, it was found that the stapes on each side were malformed, the left malleo-incudal joint was dislocated and a part of the right Fallopian Canal was impaired as to expose the facial nerve.
    Fenestration operation was performed on the left ear with remarkable improvement of hearing.
    The same procedure will be tried on the right ear in the near future.
    Review of the literature and some considerations on the development of the malformation of the case were made from the aspect of embryology.
