ジャーナル フリーIn 4 cases of otogenous suppurative meningitis, penicillin was administered intramuscularly and also intrathecally before and after operations. Three of them were cured and one died.
The adverse effects caused by intrathecal injection of penicillin were observed in two cases, manifestations of meningeal irritations, which appeared 3 to 5 hours after the injection and continued for 6 to 20 hours.抄録全体を表示PDF形式でダウンロード (465K) -

ジャーナル フリーAuthor applied the vibration of 2, 400p. min., with the amplitude 0.5 mm., to guineapigs which were confined on a plate of the vibrator in free postures.
The guinea-pigs received two or four hours of vibration a day and it was dayly continued to make the total duration: 10, 20, 30, 40, 50, 60, 80, 100 and 160 hours for nine groups respectively.
As this vibrator produced a noise of fifty db., the author made other groups of guinea-pigs receive the noise of the vibrator without the vibration, which provided a series of nine control groups.
The number and duration of rotary nystagmus of the ten hours group were reduced a little after the experiment and in company with the increase of experimental hours, the percentage of reduction augmented, even to 15 per cent. for the 160 hours group. The percentage of reduction for the control groups was in most cases less than the experimental groups.
As for Preyer's auricular reflex, 10 hours actual vibration effected a reduction of 27 per cent, in strength, while corresponding noise without vibration caused that of 10 per cent. compared to the original value before the experiment; and the longer the hours of experiment the more pronounced reduction was obtained, which amounted to 50 per cent, for 160 hours application equally for both expriment and control groups. When comparison was made between the actual vibration groups and the noise experiment (control) groups, more pronouced effect was generally observed in the former than the latter.抄録全体を表示PDF形式でダウンロード (513K) -
第二編 振動が聽器に及ぼす影響の病理組織的所見に就て山本 馨1949 年 52 巻 7 号 p. 233-237_2

ジャーナル フリーAuthor made histological examination of the auditory organ of guinea-pigs used in the preceding report.
In general, external and middle ears are in normal condition but many changes were observed in the inner ear.
Each cells of the Corti's organ were atrophied and dimmed, nuclei disappeared or were transformed.
These changes were more marked in the upper than in the lower coils of the Corti's organ.
There were little changes in the cochleal nerve and cells of the spiral ganglion. In the vestibular capsule and both acoustic maculae, there were reduction and disappearance of otholiths, otholith membranes and cell's hairs and disturbed arrangement of epithelial cells.
The change in the vestibular nerve and the acoustic macula nerve were rather slight. There were disturbed arrangement and impaired clearness of boundary of epithelial cells of acoustic cristae of semicircular canals, but little change in nervous fibers.
The changes in cochlea were more marked in the vibration experiment groups than in the control groups while the changes in the auditory organ were of the same degree in both series, which indicates that they were caused by the noise of the vibrator.
There were slight changes in the 100 hours vibration group and marked changes in the 160 hours group in the vestibule and semicircular canals, whereas there were no changes in corresponding groups of the control.
Influences upon the auditory organ by the vibration were thus localized in the vestibule and semicircular canals, foci being found mainly in acoustic maculae.抄録全体を表示PDF形式でダウンロード (544K)
