ジャーナル フリーThe vestibular functions in the pathological cases were examined with the minor rotatory stimulations. The findings were compared with those in the normal cases, especially in the para- meter of the distributions of the nystagmus frequencies. Subjects consisted of twenty cases of unilateral labyrinthine disorder, five cases of acoustic tumor and ten post-operative cases of cerebello-vermis tumor. The following conclusions were obtained in each pathological entity, respectively.
1) Unilateral labyrinthine disorder cases.
Per-rotatory nystagmus indicated the functions of the cupula-endolymphatic systems better than the post-rotatory one. However, the affected side was hardly determined by this test.
The per-rotatory nystagmus frequencies had the tedency to decrease in the course of central compensations. The vesibular recruitment phenomena were suspected in seven cases. The multiple peaks observed in the declination courses, were considered abnormal response.
2) Acoustic tumor cases.
The per-rotatory and the post-rotatory nystagmus showed the distributions of the lower frequ- encies. However, the nystagmus frequency patterns resembled those of the normal cases.
3) Post-operative cases of the cerebello-vermis tumor.
The preponderance of the nystagmus and the operative findings of the cerebello-vermis tumors did not correspond in many cases.抄録全体を表示PDF形式でダウンロード (1457K) -

ジャーナル フリーAs to the relations between tonsillitis and nephritis, many clinical and experimental studies are known nowaday. We wish here to discuss about some renal pathologies of experimental animals sensitized for a certain long period by streptococci to make chronic tonsillitis similarly seen in human tonsils. First of all, we injected repeatedly the emulsions of high powered A-type hemolytic streptococci into the tonsils of rabbits, and after a long period of continuous sensitization, tonsils were removed and the supernatant of the extirpated tonsillar tissue emulsion was injected intravenously. Then renal biopsy was made and the renal tissues were studied histologically and immunofluorescently.
Thus, we obtained the following results:
1) Post-streptococcal glomerulonephritis similar to that of human being could not obtained experi- mentally by the intratonsillar injections of hemolytic streptococci.
2) No definite interrelations were observed between renal pathology and ASLO titer nor urinary protein.
3) A certain degree of various pathological glomerular changes were observed in the renal tissues obtained by intravenous injections of extirpated tonsillar emulsions during the latter half of the sensitization period.
4) Renal glomeruli were thought to be always influenced by chronic tonsillar foci, so that the influence of chronic tonsillar inflammations to the onset, recurrence, and chronicity of nephritis could not be neglected.抄録全体を表示PDF形式でダウンロード (1930K) -

ジャーナル フリーIn the preceding paper, the authors presented the Circular Eye-Tracking Test as one of new approaches in vestibular examination. This test was performed by an apparatus in which the visual stimulus moved drawing a circle clock-wise at 120°/sec with the radius of 25. 5cm. The apparatus was set 70cm before the patient, whose eye movements pursuing a visual stimulus were recorded by ENG.
With an accumulation of our experiments, the authors could reaffirm two good advantages of the Circular Eye-Tracking Test; simultaneous recording of the horizontal and vertical components of eye movement pursuing a visual stimulus, and decrease of the artifacts by the movement of upper eyelids which often appeared in the vertical eye-tracking test.
In this study, 55 cases with central disorders were examined by the Circular Eye-Tracking Test and 23 cases showed abnormal eye movement. We classified them into three groups as follows:
i) abnormalities found mainly in the horizontal component (6 cases of congenital nystagmus and 1 case of post traumatic normal pressure hydrocephalus).
ii) abnormalities found mainly in the vertical component (6 cases including: basilar impression+ Arnold Chiari's malformation+ platybasia+ scoliosis, and Wernicke's encephalitis).
iii) abnormalities found both in the horizontal and vertical components (10 cases including plt- tybasia+ Arnold Chiari's malformation+ basilar impression+ syringobulbia, and late cerebellar cortical atrophy),
In any of these three groups, the central spontaneous nystagmus was always superimposed on the pursuit movement in the Circular Eye-Tracking Test.
The data presented here are not sufficient to affirm that the abnormalities of the horizontal and vertical components in the Circular Eye-Tracking Test are directly related to the lesions at the locations controlling horizontal and vertical eye movements respectively. But it should be noted that in not a few of these cases we found coincidence between the physiopathological lesions and abnormalities recorded by the Circular Eye-Tracking Test抄録全体を表示PDF形式でダウンロード (4201K) -

ジャーナル フリーObservations on the intra subject variability of articulatory motor function were performed in order to clearify the sensory motor feedback self-control function.
Measurements of vowel formant frequencies and voice onset time of speech sounds spoken 100 times by 5 normal male adults were performed and mean values, intra subject standard deviations and relative standard deviations were calculated.
Mean values of the first formant frequencies and the second formant frequencies showed almost the same values as those found in previous literatures.
Intra subject standard deviations of the distribution of formant frequencies were 20-60 Hz relative to the mean valures of formant frequencies, but relative standard deviations showed almost the same values, 3-6% in each vowel.
Intra subject standard deviations of voice onset time were between 5 and 12 msec. without relation to the length of voice onset time, and the relative standard deviations were the same in each consonant.
It was clarified that distributions of measurements of 100 trials showed normal distribution. The author pointed out that the self controlled physiological function works within normal range of variability which was shown by infra subject standard deviation, and relative standard deviation might be considered as self control index in the term of servo technology.
The author hypothesized that the measurement of intra subject standard deviation in speech behavior would give us useful information for the diagnosis and prognosis of speech disorders.抄録全体を表示PDF形式でダウンロード (2044K) -

ジャーナル フリーOne hundred and eighty infants and children with chief complaint of hearing loss or speech One hundred and eighty infants and children with chief complaint of hearing loss or speech mental dificiency and group with combination of these two defects. Each group was subjected to evoked response audiometry (ERA) and behavior test, and their threshold values were compared. evoked response audiometry (ERA) and behavior test, and their threshold values were compared. evoked response audiometry (ERA) and behavior test, and their threshold values were compared. The subjects of this study were 19 normal children, 126 with hearing loss, 21 with mental deficiency and 14 with hearing loss and mental deficiency. Sixty one cases of the group with hearing loss were subjected to the play audiometry which is the most reliable, and the results were compared with those of ERA.
As a result it was found that ERA threshold of normal group ranged from 20 to 50 dB (36. 1dB on an average), while it was 30 to 60dB (49. 1 dB on an average) in the mentally deficient group, showing a difference of 10 to 15dB from the normal group. And this difference deficient group, showing a difference of 10 to 15dB from the normal group. And this difference ERA and play audiometry was -10 to 20dB (6.3dB on an average), and threshold of ERA was somewhat higher than that of the play audiometry. The threshold difference between ERA and behavior test was -20 to 10dB, and ERA gave lower threshold than the behavior test, but in the group with developmental quotient less than 50 ERA threshold was higher than that of the behavior test. Every one of these groups had the peaks mainly of P2 and N2, but showed no difference in the their latency.抄録全体を表示PDF形式でダウンロード (996K) -

ジャーナル フリーClinical epidemiological investigations were undertaken on the incidence, causal factors and the adequate time for operation of harelip and cleft palate. The effect of pharyngeal flap operation on the speech was also studied.
Materials were 377 cases of harelip and cleft palate (192 males and 185 females) who were selected from the patients operated at the Department of Oto-Rhino-Laryngology, National Nagoya Hospital, between October 1948 and December 1973. Of 377 cases, there were 66 harelip, 227 cleft palate and 84 combined cases with harelip and cleft palate.
Results were as follows:
1. Incidence
i) Twelve out of 10, 153 babies born at the Hospital during 1915-1972 were the cases of harelip and cleft palate, i. e. 1 to 850.
ii) No significant difference was to be noted between the sexes.
iii) The left side was more predominant than the, right, side.
iv) No significant difference was observed between the first child and others.
2. Causal Factors
i) Family incidence was about 7.4%.
ii) Parental Factors
a) Mothers of the patients were found out more predominantly in the group who were 25-30 years of age. This is probably due to the high frequency of delivery in this age-span.
b) No significant difference was to be noted in the parent educational backgrounds.
c) The cases were somewhat more frequently found in the low-income group.
3. The adequated time for operation.
Most of harelip cases were operated when they weighed about 3.5 to 4.5 kg.
In cleft palate cases, good results in speech was obtain in the cases who were operated between 1 and 2 years of age.
4. Effects for speech.
The patients treated with speech therapy after the operation showed satisfactory results, and the better results were obtained in the cases with high I.Q..
In the patients with poor speech, the pharyngeal flap operation was done with satisfactory results.抄録全体を表示PDF形式でダウンロード (1106K) -
