    The histopothological study of both cochleas of the inner ear was performed in an autopsy case which had been treated with a total dose of 55 g of streptomycin sulfate against pulmonary tuberculosis.
    Each hair cell was identified on the cochlear reconstruction of a whole mount specimen in both ears. Both inner and outer hair cells were counted in number separately: Outer hair cells 10121 (right) and 8529 (left), while inner hair cells 3140 (right) and 3141 (left). Both inner and outer hair cells were missing near the base of the cochlea due to streptomycin ototoxicity and probably due to ageing degeneration as well. Other degeneration patterns due to streptomycin included a more pronounced fragility of outer hair cells as compared with inner hair cells particularly in the basal part of the cochlea, and the loss of outer hair cells of the first row which was more distinct in the basal turn of the cochlea.
    The loss of inner hair cells was scarcely detected in the apical part of the cochlea, while that of outer hair cells was more pronounced in the apical part than in the middle part of the cochlea.
    Remaining outer hair cells were 76% (right) and 64% (left) of the normal figures, while inner hair cells were 92% in both sides of the ears. The reduction of both inner and outer hair cells was supposed to be the cause of the threshold elevation of both ears in the audiogram. However, the loss of hair cells seems to be too mild to explain the hearing loss. The discre- pancy between the threshold elevation and the loss of hair cells could be produced by the presence of functionally impaired hair cells.

    Power spectral analysis of auditory slow vertex responses of five normal hearing adults was carried out. Analysis time is 512 msec and 1024 msec.
    Results:
    1, When acoustic stimuli were perceived, the power spectra of 3-9c/s at 512 msec analysis time were higher than at 1024 msec analysis time, and when acoustic stimuli were not perceived, there were little differences between the two analysis times.,
    2. The power spectra at 512 msec analysis time, 10 dB stimuli were high at 4-9 c/s, with a peak at 4-5 c/s.
    3. The sum of power spectra of 3 c/s to 9 c/s at 1024 msec analysis time showed clear difference between auditory evoked responses and spontaneous brain activity. The sum at stimulations increased with stimulus intensity.
    4, The sum of power spectra of 4 c/s to 9 c/s at 512 msec analysis time, showed clearer difference between auditory evoked responses and spontaneous brain activity than at 1024 msec analysis time.

    Three cases of acute cerebellar ataxia in children were reported and reviewed from the otoneurological point of view.
    Case t: A 6-year-old boy, several days after the development of skin eruption of chicken pox, complained of an occipital headache with a low-grade fever, followed by a staggering gait and incoordination of the arms. Otoneurological examination showed him to have an ataxic gait, an intention tremor, a bradylalia, dysmetric eye movement, an ataxic pursuit pattern for the eye tracking test (ETT). However, the results of the optokinetic nystagmus pattern (OKP) and rotation tests were within normal limits. These data suggest that the lesion dispersed diffusely within the cerebellum.
    Case 2: A 10-year-old boy, several days after an upper respiratory infection, complained of epigastralgia, an occipital headache and a staggering gait. Otoneurological examination showed him to have an ataxic gait, a dysdiadochokinesia of his left hand and upward vertical positional and positioning nystagmus and backward stepping. However, the results of OKP, rotational and ET tests were within normal limits. These data suggest that the lesion was localized in the vermis of the cerebellum.
    Case 3: A 3-year-old girl, 6 days after the development of skin eruptin of chicken pox, complained of a staggering gait and incoordination of the arms. Otoneurological examination showed her to have an intention tremor, wide-based back- and forward-stepping and an ataxic gait. However, neither nystagmus nor abnormal eye movement were observed and the results of optokinetic nystagmus and rotational tests were within normal limits. These data suggest that the lesion was within the cerebellum.
    The clinical courses of the three cases were very good, and they recovered completely within a few weeks.
    In conclusion we stress that the responsible lesion of acute "cerebellar" ataxia was just within the "cerebellum", and the participation of the brain stem could be excluded.

    A radiographic survey was performed on 50 temporal bones of 25 skulls in order to study the relationship of the facial canal to the tympanomastoid fissure.
    A fine metal wire was glued on the tympanomastoid fissure and the facial canal was filled with a few wires, then the specimens were examined in antero-posterior and lateral projections.
    The horizontal distances between the facial canal and the tympanomastoid fissure were measured at four points, that is, 5 mm, 10 mm, 15 mm from "pointer" along the tympanomastoid fissure, and "pointer" itself.
    The results are as follows:
    The means of the distances were 0.44 mm, 0.06 mm, 0.46 mm and 2.02 mm, respectively, posterior to the tympanomastoid fissure at "pointer", 5 mm, 10 mm and 15 mm on the right side, and 0.66 mm, 0.22 mm, 0.78 mm and 2.34 mm at each point on left side.
    The means of the depth were 8.52 mm, 10.71 mm, 11.49 mm and 10.07 mm medial to the tympanomastoid fissure at each point on the right side and 8.34 mm, 10.83 mm, 11.55 mm, 10.16 mm on the left side. These numerals did not indicate the horizontal distances between the center of the facial canal and the tympanomastoid fissure, but the distances between the proximal mark of the facial canal and the tympanomastoid fissure.
    The standard deviation was the smallest at the point of 10 mm, and the next smallest at the point of 5 mm.
    From the facts above mentioned, it can be concluded that the distance variation between the facial canal and the tympanomastoid fissure was tympanomastoid fissure was the smallest in the range of 5-10 mm from the "pointer", and in such a range, the facial canal could be detected between 2 mm anterior and 3 mm posterior to the tympanomastoid fissure at the depth of around 8-13 mm.

    Recently the treatment of the olfactory disturbance has been investigated in many institutions extensively. However, the fruits of these studies were still far from perfect. In this study the treatment of the disturbance of the olfactory epithelium was investigated, because etiology of the olfactory disturbance was considered mostly as the abnormal change of the olfactory epithelium caused by nasal diseases (sinusitis, allergic or hypertrophic rhinitis etc).
    The results of treatment 1376 outpatients visiting the olfactory clinic of the Department of Otorhinolaryngology at Showa University were presented as follows:
    1) 1376 patients were divided into 4 types, respiratory olfactory disturbance, epithelial olfactory disturbance, combined olfactory disturbance and central olfactory disturbance, and 96% of them were of epithelial and combined type.
    2) In treatments 2 or 3 drops of 0.1% *-methasone or 0.1% dexamethasone nose drop were applied on olfactory mucosa in the patients, head down position as basic treatment.
    3) As the result of treatment, 87.5% of respiratory type, 68.6% of epithelial type and 75.7% of combined type were recovered completly or remarkably but none of the central type recovered.
    4) Side effects were studies after the administration of 5 ml/week of 0.I% dexamethasone or 0.1% *-methasone solution for 16 weeks, and the results of rapid ACTH test and the other adrenocortical function studies were normal.
    By this treatment, nearly 70% of the patients visiting our clinic were recovered completly or satisfactorily.
    Therefore nose-drops of adrenocortical hormone were considered very useful for the treatment of olfactory disturbances.

    A question has been presented as to whether the basophilic granular cells in allergic nasal secretion belong to the blood basophils or the tissue mast cells. The purpose of this study is to answer this by electron microscopic observation on blood basophils and basophilic granular cells in the nasal secretion and mucous membrane.
    From the results obtained, two types of basophilic granular cells were observed in both nasal secretion and mucous membrane. One of these, similar to the blood basophil, was small, round or oval in shape and lobulated in the nuleus, with a uniformly fine granular pattern of the specific granule. The other, similar to the tissue mast cell, was large, pleomorphic or oval in shape, mononucleated and varied in the pattern of the specific granule from granule to granule, showing scrolls, lamellae, reticula or granules.
    The majority of the basophilic granular cells in the nasal secretion belonged to the former type of cells, while the majority in the deeper layer of the mucous membrane belonged to be latter, and two-fifth of cells close to the subepithelial layer belonged to the former and the remaining three-fifth to the latter.
    Conclusively, the majority of the basophilic granular cells in nasal secretion belongs to the blood basophils, and mainly emigrates from the subepithelial small blood vessels of the nasal mucous membrane through the intraepithelial space.

    One hundred and eleven children with bilateral hearing loss of unknown etiology have been followed up for a period of 1 to 6 years. Audiograms were studied from the view point of progression of hearing loss. Children were classified into 2 groups of 47 hereditary cases and 64 cases with unknown etiology.
    The conclusions obtained were as follows.
    1, Average hearing level deteriorated slowly during the observation period of 1-6 years. No difference was observed between both groups of the hereditary and unknown. Average deterioration was accounted for about 10 dB in 5-6 years.
    2. In 39 cases out of 111 cases (35, 1 % : hereditary group 29.8% and unknown group 39.1%), hearing level detetriorated more than 15 dB.
    3. The dominant shape of audiograms in cases with progressive hearing loss was gradually sloping, and in a few cases abrupt shape.
