JOURNAL FREE ACCESSThe author observed rontgenographically the running caurse of Fallopian canal in 52 crania of adult japanese injecting contrastmedium into Fallopian canal from Foramen stylomastoideum in regarding to the forms of crania, shorthead or dolichocephalus, to the degree of pneumatisation of middle ear, and to the age.
The result was as follows;
1) Regarding to the relation between the middle ear pneumatisation and the form of cranium, the better pneumatisation was found in shorthead than in dolichocephallus. The former showed a good developed pneumatisation in 80% of cases.
2) The vertical type of the descending part of the facialnerve was perceived in 55% by Schuller's method, being most frequent.
The type, in which the second bending bent sharply was more frequent in dolochocephallus than in shorthead. This finding is interesting.
3) By the second method of roentgenography, which the author originated, the oblique type of the descending part of the facialnerve was most frequent (68%). The type, in which the second bending sharply bent, was found frequent in dolichocephallus than in shorthead by the same method.
4) On the relation between the middle ear pneumatisation and the running course of the Fallopian canal, observed by Schaller's method and author's second method, the sharply bending type, which is seemed to be abnormal, was more frequent among the poorly developed pneumatisation. The vertical type of the Fallopian canal through Schaller's method was found frequently in various type of pneumatisation, but the oblique type was almost absent in poorly developed type, and become increasingly frequent as pneumatisation better developed.
The vertical type by the author's second method become more frequent as the pneumatisation well developed. The oblique type was found often in all types of pneumatisation.
5) Regarding to the age, the relationship between the middle ear pneumatisation and the running course of the Fallopian canal was not significant.
These results were interesting for the judging of the running course of the Fallopian canal at the middle ear area by operation.View full abstractDownload PDF (6657K) -
especially, the Influence upon the Form and the Function of the Internal EarMasayoshi Taguchi1958 Volume 4 Issue Supplement6 Pages 379-395

JOURNAL FREE ACCESSAuthor selected the method of Lindsay, as an experimental obstruction of aqueductus cocholeae and tried a modified procedure of this method on cats. As the results of studied morphological and functional findings of the internal ear, which were succeded in 7 cases, followings were shown:
1) When the operstion was successful and the condition of the animals was good, this very obstruction was performed 5 weeks. The more thick and solid obstruction demand over 7 weeks.
2) There were a few influence of the obstruction upon the surrounding area, and no particular change on cocholea, veatibule and semicircular canals except some special cases.
3) Animals restore the almost normal function after 5 weeks, even the appearance of the slightest symptom of the reactive, aseptic and serous labyrinthitis may be presumed.
4) Concerning the attitude of membrana Reissneri, its rising and sinking situation cannot be decided by the degree of obstruction or by its duration.
5) The function of the internal eai was kept in the normal range.View full abstractDownload PDF (7520K) -

JOURNAL FREE ACCESSUrn die Verhältnisse der Blutgefassverteilung des Trommelfells von Vertebraten vergleichendanatomisch zu untersuchen, hat Verf. den normalen Katzen, Eidechsen, Fröschen u. a. die Tuschelösung mit Gelatinzusatz in die Blutgefässe eingespritzt und kurz zusammenfassend folgende Resultate erhalten.
1) Die das Trommelfell der Katze unmittelbar ernährende Arteria ist die A. mallearis, welche von der A. auricularis profunda ausgeht, und der Rand des Trommelfells wird von den Übergangsästen der Kapillararterien der Tiefe des ausseren Gehörgangs sowie des Tympanums ernährt.
2) Nachdem die Venen des Trommelfells der Katze den Plexus venosus manubrii mallei und Plexus venosus marginalis membranae tympanica gebildet haben, treten sie in die V. mallearis, die V. tympanica und die V. stylomastoidea ein und fliessen mit vielen Rami communicantes mit der V. temporalis superficialis, der V. carotis interna und der V. jugularis superficialis dorsalis zusammen.
3) Das Trommelfell der Eidechse wird von der A. membranae tympani ernährt, welche von der A. carotis cerebralis ausgeht, und dessen Rand wird von den Übergängsdsten der A. membranae tympanica marginalis und der Kapillararterien des Tympanums ernährt.
4) Die Venen des Trommelfells der Eidechse versammeln sich zur V. mallearis und der V. membranae tympanica marginalis, und munden durch die V. membranae tympani in die V. carotis interna ein.
5) Das Trommelfell des Frosches wird von der A. membranae tympani, einem Ast der A. tympanica posterior, ernährt und der Rand wird von den Übergangsästen der Kapillararterien des Tympanunis ernährt.
6) Die Venen des Trommelfells des Frosches gehen häuptsachlich in die V. membranae tympani uber und miinden durch die V. tympanica superior in die V. carotis interna ein, aber die Venen der unteren Halfte des Trommelfells münden in die V. facialis ein.
7) Die Verhältnisse der Blutgefässverteilung des Trommefells von obenerwähnten drei Arten Vertebraten sind einander sehr ähnlich, und es finden sich in allen dreien die A. mallearis und das radiäre Blutgefäss. Auch der Plexus venosus manubrii mallei und der Plexus venosus marginalis membranae tympanica sind vorhandenView full abstractDownload PDF (9465K) -
Part I. Experimental Study on the Prophylactic Effect of Vitamin B1 on Auditory Fatigue and its Recovery in the Human BodyMasato Ando1958 Volume 4 Issue Supplement6 Pages 412-424

JOURNAL FREE ACCESSThe subjects studied were divided into 4 experimental groups on the basis of Sawada's urinary test: Group I-Group IV according to its reaction of ++, +, ±, or -, respectively. Group I and Group III were administered orally with 10mg. and 3mg. of vitamin B1 daily for 20days, respectively. Control values were obtained from Group II and IV. Prior to and after the course of administration, all groups were exposed to the noise (110 phons), the auditory fatigue and its recovery being observed. Both Group I and III showed the effect of vitamin B1 on those phenomena in the higher frequencies (especially C5). On the contrary, in Group II and IV there was no noticeable change in the auditory fatigue and its recovery. Thus, vitamin B1 was found to be prophylactically effective for a man's acoustic trauma, normal and lacking in this vitamin alike.View full abstractDownload PDF (1921K) -
Part II. Experimental Study on the Effect of Vitamin B1 on the Human Autonomic Nervous System exposed to NoiseMasato Ando1958 Volume 4 Issue Supplement6 Pages 425-445

JOURNAL FREE ACCESSAdrenaline test of Dresel and repeated sphygmomanometry of systolic pressure were employed to study the effect of vitamin B1 on the autonomic nervous system of the subjects under 2 conditions of resting and exposure to noise (110 phons), respectively. In adrenaline test the half of all cases for study were injected with 10 mg. of vitamin B1 daily for 10 days. It was concluded that vitamin B1 induced the tendency of alteration from S to V type in Dresel's test and becoming less sensitive to adrenaline in every administered groups against almost no change in control groups.
As to sphygmomanometry, the subjects in the first experiment were divided into 4 groups on the basis of Sawada's urinary test, two groups of positive reactions being administered orally with 10 and 3mg. of vitamin B1 daily for 14 days, and the classification and oral administration of the subjects in the second experiment were same as Part I. The administration of vitamin B1 to the persons, normal and vitamin B1 deficient, resulted in lowering the variations of systolic pressure caused by noise.View full abstractDownload PDF (2646K) -
Part III. Study on the Effect of Vitamin B1, on Acoustic Trauma by Staining of Ribonucleic Acid in the Spiral Ganglion Cells and Pryer's Reflex of Guinea PigsMasato Ando1958 Volume 4 Issue Supplement6 Pages 446-459

JOURNAL FREE ACCESSGuinea pigs, injected with 1 mg. of vitamin B1 daily from a week before noise exposure to the experiment, were sacrificed on the second, seventh, fourteenth, and twenty-first days after 3 hour's exposure to noise (100 phons). As a result of microscopic observations made on stained ribonucleic acid (RNA) in the spiral ganglion cells, vitamin B1 seemed to reduce the decrease of RNA in cytoplasm of the ganglion cells and improve its recovery rate.
Furthermore, Pryer's reflex of guinea pigs, given the same course of vitamin B1 (5 mg. daily), was examined on the first, seventh, and fourteenth days after repeated 6 hour's exposure to noise (110 phons) a day for 3 days, demonstrating that vitamin B1 brought about early reappearance of the reflex inhibited by noise, particularly in a range of high frequenciesView full abstractDownload PDF (6728K)
