I. ObjectiveThe present study was undertaken in order to determine the onset of monaural deafness, especially whether it is congenital or acquired, making an investigation into the sense of sound direction in monaural hearing impairment and monaural deafness and compairing them between hearing-impaired patients and normal hearers.II. SubjectsThis study was carried out on 26 patients with monaural hearing impairment, 22 patients with monaural deafness and 10 normal hearers.III. MethodsA circle with a radius of 1.3m was drawn around a fixed patient's position in a sound proof room, and the circle was divided into 16 directions at an equal angle of 22.5°. A blindfolded hearer was instructed to listen to a speaker for white noise of 60dB (A) for one second and verbally answer in which direction he heard the noise. The normal hearers were tested in 4-, 8-, and 16-directions, and the hearing-impaired patients were tested in only 8-directions.IV. Results1. Normal HearersThe rate of correct answers decreased with increasing directions of sound.The incorrect answers in 4-direction testing were only confusion between forward and backward directions, and similar incorrect answers were made in 8- and 16-direction testing. All other incorrect answers were errors of less than 45°.2. Monaurally Hearing-impaired PatientsThe rate of correct answers on the whole was low.There was such a relationship between the rate of correct answers and the mean hearing level of patients that the total rate of correct answers decreased with increasing hearing impairment. This correlation was statistically significant, and there was a still more significant correlation between the degree of hearing impairment and the rate of correct answers as to the right and left directions.Incorrect answers were errors of90° or less on the healthy side, while errors were made for all directions on the affected side.3. Monaurally Deaf PatientsThe rate of correct answers was by far lower on the affected side.Whereas many errors were within 45° on the healthy side, errors were made for all directions on the affected side.Judging from the onset of hearing loss, the monaurally deaf patients were divided into a group of 8 patients who obviously had sudden aquired deafness and a group of 9 patients who were presumed to have congenital monaural deafness. The mean rate of correct answers of the former group was superior to the latter group's, particularly on the effected side.

Thirty-five patients with cedar pollinosis were studied for clarifying the specificities of HLA antigens. Identification of HLA types was based on the result of the lymphocyte microcytotoxity test. There was a significantly high incidence of HLA-A10 and HLA-BW15 in cedar pollinosis.The incidence of HLA-A10 was 11.7% in the control group and 68.6% (X2=49. 1, p<10-6, Pc <10-5) in the patients, while that of HLA-BW 15 was 37. 1 % (X2= 12.8, p=5×10-', Pc=8 × 10-3) in the patients compared to 11.7% in the control.

By means of pellet tracking technique using an x-ray microbeam system, observations of articulatory movements were made on clinical cases of cerebellar degeneration. In some selected cases, electromyographic study was also performed. The data were specifically examined with reference to the range, velocity and consistency (reproducibility) of the movements of the articulators as well as to the pattern of coordination of the different articulators involved. It was found in the case of ataxic dysarthria of cerebellar origin, that the dynamic patterns were best repesented by difficulty in initiation of purposive movements and inconsistency of artieulatory movements, particularly in repetitive production of monosyllable. On electromyography, breakdown of the rhythmical patterns in the articulatory muscles was quite obvious in the repetition of monosyllables. It was suggested that analysis of dynamic aspects of the dysarthrias shoulc he a promising approach for elucidating the nature of central problems of speech productior and for differential diagnosis of various types of dysarthrias.

Six patients with nasal allergy due to Japanese Apricot pollen which are called "Ume" pollen were clinically examined. All cases had hyperrhinorrhea and nasal obstruction with ocular symptoms, and one of them also had itching in the pharynx. They have lived for 8 to 47 years near by a large grove of Japanese apricot and 4 of them were fruit-growers. Among these four cases, three have suffured from nasal and ocular symtoms while they were working in the grove. These cases had positive skin reaction to clude "Ume" pollen extract, and five patients also reacted to nasal and ocular provocative tests.Serum IgE value by RIST was distributed from 98 to 2300IU/ml (mean value 887IU/ml). Specific anti-"Ume" pollen IgE in the serum was measured by BrCN activated RAST method, and serum value of five patients was 1.6 timed to 3.5 times higher than that of non-allergic subjects.Air-borne "Ume" pollen collected in a grove were observed from the beginning of February to the middle of March, and maximum grain count was 43 per cm2 in 24 hours.

The discrimination of mono-syllable words (67S word-list) pronounced by a male and a female speaker was investigated in noise in 39 normal hearing subjects. The subjects listened to the test words at a constant level of 62 dB together with white or weighted noise in four S/N conditions. By processing the data with logit transformation, S/N-discrimination curves were presumed for each combination of a speech material and a noise. Regardless of the type of noise, the discrimination scores for the female voice started to decrease gradually at a S/N ratio of +10dB, and reached 10 to 20% at-10dB. For the male voice in white noise, the discrimination curve was similar to those for the female voice. On the contrary, the discrimination score for the male voice in weighted noise declined rapidly from a S/N ratio of +5dB, and went below 10% at -5dB. The discrimination curves seem to be shaped by the interrelations between the spectrum of the speech material and that of the noise.

The spinal location of individual motor nuclei of the thoracic dorsal paravertebral muscles was investigated in the cat, using retrograde labelling of motoneurons with horseradish peroxidase (HRP). HRP was injected into the peripheral nerves innervating Mm. rotatores, M. multifidus, M. spinalis dorsi, M. longissimus dorsi and M. iliocostalis. The retrogradely-labelled motoneurons of a particular muscle were arranged in a longitudinal column-like fashion for the length of one segment in a localized area of the spinal ventral horn (the ventromedial or the lateromedial nuclei in lamina IX of Rexed). To compare the relative locations of the motor nuclei of different muscles in the ventral horn, two different muscle nerves (one for each side) were injected with HRP bilaterally at the same segmental level. The motor nuclei of Mm. rotatores, M. multifidus, M. spinalis dorsi, M. longissimus dorsi and M. iliocostalis were arranged in this order from the medial to the lateral portion of the ventral horn. This mediolateral order of arrangement of the motor nuclei was discussed in relation to the classification of the dorsal paravertebral muscles based on the comparative anatomical study.

Twenty normal hearing young adults ingested 1.4ml alcohol per kg body weight over 60 minutes. Then the blood alcohol levels, breath alcohol levels were measured by Dupont ACA blood analyzer and DPA-2 breath analyzer. Also the thresholds and the amplitudes of the acoustic reflex were measured by impedance audiometer ZO-72, using 1.5sec., 500Hz., pure tone stimulation contralaterally in 13 persons, and ipsilaterally in 7 persons. First, the thresholds were decided and then the amplitudes were recorded after the stimulation by the sounds of 20dB more than those of before drinking alcohol. The results were as follows: 1) In 13 persons who the stimulation were given contralaterally, the amplitudes were decreased at the point of just finishing drinking. Four persons showed remarkable decrease, while five showed no significant change. 2) In 7 persons, who the stimulation were given ipsilaterally, the thresholds were increased at the points of just finishing drinking, 30 minutes later, 60 minutes later. No variability was found among them. 3) No significant relations were found not only between the blood alcohol levels and the changes of the thresholds, but also between the blood alcohol levels and the changes of the amplitudes. From the above mentioned, it was concluded that the acoustic reflex was depressed when people drink alcohol, and people will get morepossibilities of suffering from acute sensorineural healing loss if they are exposed to loud sounds while drinking, like in discos.

A standard olfactory acuity test using T & T olfactometer has recently been developed and gradually becomes in wide use, while the conventional intravenous olfaction test is also widely used.In the present experiment we studied the relationship between results of these olfactory tests and prognosis in 180 patients with olfactory disturbances who had received the nose-drop treatment with glucocortico steroid hormone. As a result, cure or improvement was attained in 88 percent of the patients who gave a positive reaction to the standard olfactory acuity test and in 66 percent of those who were judged to be scaleout in this test.In the case of the intravenous olfaction test, cure or improvement was attained in 90 percent of cases which gave a positive reaction and in 40 percent of the negative cases. Particularly in reference to the patients who gave a negative reaction to the intravenous olfaction test, one out of 65 cases attained cure and 39 cases remained unchanged. The intravenous olfaction test proved most effective among the tests to tell the prognosis of olfactory disturbances.

The bone-conducted vowels were picked up by the vibration transducer of the accelerationtype applying to three anatomical sites on the heads (forehead, upper jaw and mastoid region)of the healthy adults.A comparative studies on the speech signals from these three regions of the head were done acoustically. The results were summarized as follows; i) for the pickup of speech signals from the body surface, the vibration transducer of small acceleration type (Rion Co. PV-06)was the most satisfactory in point of a signal-to-noise ratio, intelligibility of the speech and practical use. 2) the relative intensities of the speech signals were decreased in regular order i, u, e, o and a. 3) the spectral characteristics of these vowels were highly similar to those which were recorded from the micropone at the position in the distance of 30 cm from the lips, although there was an inclination of the increased low-frequency components with the decrease of high-frequency in the spectrum. 4) from the results of the articulation score, intelligibility of the vowels was much better in recorded sounds from the upper jaw and forehead compared with that from the mastoid region.

It is well known that histamine is the most important chemical mediator of nasal allergy, and histamine hypersensitivity of the nasal mucosa has been also recognized in the patients with nasal allergy. Therefore, the degradation or inactivation of histamine released from basophilic cells following reaginic antigen-antibody reaction is very important in the patients from a view point of the defence mechanism of the body. The purpose of this study is to investigate the levels of plasma histaminase of allergic patients both in pollen season and in season without pollen of Japanese cedar. The patients have developed clear symptoms due to allergen challenge during the pollen season. Higher plasma histaminase activity was revealed in pollen season than that out of season. Furthermore, close relations were recognized among the plasma histaminase activity and nasal symptoms, local findings, eosinophils in nasal secretion, and histamine sensitivity of nasal mucosa during the pollen season.

1984年から1998年の15年間に関西医科大学耳鼻咽喉科において手術を施行した甲状腺分化癌を対象に統計学的観察と予後因子の検討を行った.対象症例は乳頭癌177症例, 瀘胞癌50症例, 男性45名, 女性182名, 年齢は13歳から89歳であった.年度別症例数から甲状腺腫瘍症例の増加, 特に乳頭癌の増加が確認された. 一方瀘胞癌の症例数の増加傾向は見られなかった.年齢分布として乳頭癌は40代から60代にpeakを認め, 瀘胞癌は50代にpeakが認められた.原発巣切除に関して, 乳頭癌はT因子が大きくなるにつれ, より広い原発巣切除が行われていたが, 瀘胞癌は術前, 術中に確定診断がつきにくいためか, 峡葉切除術が大部分 (70%) を占めていた.リンパ節郭清に関して, 乳頭癌症例はTが大きくなるに従い, より広い範囲の郭清術が施行されていた. 一方瀘胞癌症例は原発巣切除と同様確定診断がつきにくいためか, リンパ節郭清は70%がD1領域郭清であった.局所再発が22症例, 遠隔転移が6例に認められた. 局所再発22症例中手術で14例がsalvageできた.死亡症例は17症例に認められ, 乳頭癌12症例 (原病死は11症例), 瀘胞癌5症例 (原病死は2症例) であった. 原病死13症例の中でT4症例が10例, T3症例が3例, Nla症例が3例, Nlb症例が8例を占めていた. 死亡症例に関してはやはり進行症例が多かった.予後因子としてT, N, M, 年齢, 性別を対象として検討した. 乳頭癌の予後因子は被膜外浸潤, 遠隔転移, 年齢であり, 瀘胞癌の予後因子は遠隔転移であった.乳頭癌の5年生存率は93.0%, 10年生存率は88.8%であった. また瀘胞癌の5年, 10年生存率は93.5%であった.今回は分子生物学的検討, 癌遺伝子の検討は行わなかったが, T1N0乳頭癌症例で頸部再発を認めたことから今後はこれらの検討も必要と考えられる.
