ジャーナル フリーThis is the final report of a series on our study of the equilibrium function of school children in Kanagawa Prefecture, Japan. Standard values on four kinds of screening tests were proposed as boundaries dividing well developed and underdeveloped equilibrium functions.
As screening tests, the one foot standing test in the air plain position with eyes open, the walking test with eyes closed, the twice-rotating stepping test with eyes closed, and the railwalking test with eyes open were carried out. In the fifth report, it was reported that there was no significant correlation between the values of the above mentioned screening tests and those of selective equilibration tests such as the blind-folded vertical writing test, statokinesimetry test while standing erect, or the spontaneous, positional and positioning nystagmus test, in the same test subject.
Both sets of these screening tests were examined in 225 school children in one primary school, Hiratsuka City, Kanagawa. The relationship between the value of the selective tests in the normal group, whose results on all screening test remained within the standard value, and those of the other group, which showed a worse value than the standard value in the screening tests in school was reexamined in this study. The matching of sex and grade was tried.
No correlation between the result of the screening tests and that of the selective tests was statistically confirmed.
It was the conclusion of our study that the results of the screening tests should be used to detect children with underdeveloped equilibrium functions and to encourage them to improve their equilibrium functions in physical education class.抄録全体を表示PDF形式でダウンロード (537K) -

ジャーナル フリーDepartment of Otolaryngology, Tokyo Medical and Dental University, School of Medicine, Tokyo The distribution of basophiloid cells in nasal mucosa was examined both in the patients of nasal allergy and normal controls. Basophiloid cells were stained in alcian blue (P.H. 5.8) with 0.4M MgCl2.
1) The basophiloid cells in the nasal mucosa of allergic patients were far outnumbered those of normal controls.
2) The basophiloid cells in the epithelial layer were very few in normal controls.
3) In allergic nasal mucosa, the most numerous basophiloid cells were found in the upper lamina propoia of the mucosa.
4) No difference of the number of basophiloid cells was found between ciliated area and nonciliated area except deep lamina propria of the mucosa.抄録全体を表示PDF形式でダウンロード (524K) -

ジャーナル フリーBlood flow at radiating arteriole of inner ear was measured with direct observations method in anesthetized guinea pigs, prior to and after drug (e. i. ADP and norepinephrine) injections into the unilateral common carotid artery. Value of blood velocity was determined from the displacement of plasma space ranning through the radiation arteriole per one second with the moving picture records.
Injections of ADP 0.1 and 3mg/kg induced the decrease of blood flow and arterial blood pressure (BP), and this effect almost recovered within two min. But when a further increase of ADP dose (up to 25mg/kg or more) was given, recovery time of blood flow became prolonged or the irreversible damage was observed.
A small dose of norepinephrine (0.01, 0.15mg/kg) administration produced both the increment of blood flow and arterial BP. Its increment of flow velocity was directly related to increase in systemic BP. However, a large does of norepinephrine (1.2 and 2.5mg/kg) adminis-tration led to the decrement of blood velocity irrespective of increase of BP. This phenomenon became obvious when animal's BP level was low. The dilation of blood vessel was observed after norepinephrine injection.
When the blood flow velocity of radiating arteriole stopped after ADP or norepinephrine injection, its vascular lumen was completely obstructed by the aggregated red blood cells.
These observations might represent one of the mechanisms of repeated human deafness and tinnitus.抄録全体を表示PDF形式でダウンロード (2361K) -

ジャーナル フリーSpeech levels and discrimination scores under various noise conditions were studied in fourteen individuals with normal hearing in order to clarify actual communication within noise. The noise conditions of this study consisted of three kinds of different frequency distributions based on three types of representative frequency distributions found in the investigated daily noises. The three kinds of noises were produced by a noise generator through a one-third octave band mixer. The A-weighted noise levels used varied in 10dB steps from 50dB to 90dB. Under these noise conditions, voice levels obtained for face-to-face communication 0.3 meters from talkers uttering Japanese monosyllables were investigated. Speech discrimination scores obtained according to the voice levels were analyzed. Intelligibility of consonants obtained by further analysis of the speech discrimination tests were also investigated. The results indicated that all subjects adjusted the level of his voice and maintained it in accordance with the Aweighted noise level using a normal level of effort; that different noise spectra had no effect on voice level; and that speech discrimination scores and intelligibility of consonants were affected by the frequency distributions of the noises. In selecting hearing aids for those with sensorineural hearing loss, the results of this study should be useful for understanding actual communication in noise and for setting up the test conditions for the selection of a hearing aid with optimum electroacoustic performance.抄録全体を表示PDF形式でダウンロード (839K) -

ジャーナル フリーA compulsory sinusoid wave vibration ranging from 30 to 300Hz was induced to the vocal fold of fresh excised human larynxes by pressing a vibrator on the midline of the thyroid cartilage. The vocal fold vibration, thus created, was measured and recorded as a function of frequencies and Q-values of the resonance using Ultrasonic Pulse Methods.
The resonance pattern of the vocal fold was measured and recorded under the loading of mass and longitudinal tension.
From the resonance characteristics, damping ratio, effective mass, and effective stiffness of the vocal fold were estimated.
The results obtained were as follows:
1. The resonance characteristics were almost equal before or after vertical incision of the midline of the posterior wall of the larynxes. The mean value of the resonance frequency was approximately 100Hz, while the Q-values ranged from 2.0 to 3.0.
2. Under the loading of longitudinal tension posterioly, as the tension increased, so did the appearance rate of the secondary resonance wave. And the secondary resonance frequencies and Q-values also increased in proportion to the tension given to the vocal fold. On the other hand, the primary resonance frequency was always constant (about 100Hz), regardless of the given tension. The Q-values of the primary resonance wave were also constant, ranging from 2.0 to 3.0.
3. Under mass loading, as the mass increased, the resonance frequencies and the Q-values of resonance decreased. When the mass was over 60mg, the resonance frequency had a trend to be leveling off, probably because of the change in the stiffness of the vocal fold.
4. Damping ratio, effective mass, and effective stiffness were estimated as follows:
Damping ratio:0.21±0.04
Effective mass:0.13±0.02g
Effective stiffness:51±8k dyne/cm抄録全体を表示PDF形式でダウンロード (3858K) -

ジャーナル フリーThirty three patients of cervical nodal metastasis from unknown primary were reported and discussed. They admitted Niigata Cancer Center Hospital since 1964 to 1983.
1. Limited to the twenty two patients who were treated by otolaryngological department, the incidence of unknown primary was 2.7%.
2. In 6 cases primary sites were detected. Five cases of them were tumors of head and neck origine and another was a tumor of infraclavicular region origin.
3. Histological diagnosis of metastatic nodes were squamous cell carcinoma (51.5%) carcinoma simplex and anaplastic carcinoma (24.2%) and the others (24.3%).
4. Crude survival rate was 15.6% (3 year) and 10.0% (5 year). No one survived whose metastasis occurred in the supraclavicular lymph node and/or whose primary site was found after the initiation of the therapy. Difference of survival rate was not detected between neck dissection with radiation group and excision or biopsy with radiation group.抄録全体を表示PDF形式でダウンロード (588K) -

ジャーナル フリーTwenty patients with recurrent infections diseases (angina, sinusitis and parotitis) have received immunotherapy with Broncasma Berna to study the clinical effect and the change in various serum resistance factors. Immunological parameters such as hemagglutination titer, C3 and fibronectin were measured before and after the immunotherapy. Overall clinical effect was evaluated from the reduction of infections frequency and improvement of local findings and so forth.
Clinical effect: In 80% of twenty patients were observed the reduction of infectious frequency and improvement of local findings.
Immunological parameters: Hemagglutination titer against bacteria contained in Broncasma Berna showed upward tendency and increase of its titer against Staphylococcus aureus was observed statistically (p<0.05). Fibronectin showed significant increase after treatment (p<0.001). Marked changes were not observed in other parameters.
It was suggested that Broncasma Berna was effective in immunotherapy and the effect might be due to opsonic activity.抄録全体を表示PDF形式でダウンロード (878K)
