    It is a well known fact that the amplitude of cochlear potentials is in linear relation with the sound pressure. From this relationship, it was possible to estimate quantitatively the function of the conductive organ in the middle ear. However, it was very difficult to keep the stable recording of the cochlear potentials over a long period of time because recorded cochlear potentials were greatly affected even by slight change in the recording condition. After analysing the causes of instability in recording the cochlear potentials, the authors established the technique of the stable recording. The factors of unstable recording of the cochlear potentials were as follows:
    1) The instability in the sound field.
    2) The leakage between the recording electrode and the ground, which was affected by the amount of the labyrinthine fluid and the exudate from mucous membrane in auditory bulla.
    3) The damage of labyrinth by flowing out of the labrinthine fluid.
    Authors′ new thchnique:
    The drill made of 2O0μ steel wire was insulated by silicon varnish and was driven into the cochlea with the boring-machine which was the micro-motor attached to Peterf-type micro-manipulator. This drill was the recording electrode. Then the location and the depth of the electrode driven into the cochlea were regulated by the micro-manipulator and the labyrinth was not damaged because of no gap between the bored hole and the drill. The mucous membrane in the auditory bulls was injured so little that the exudate was scarcely observed and the leakage between the recording electrode and the ground was so small that it was negligible.
    By this technique, stable recording was almost always obtained with the change with in 1 db for over 30 hours.

    It was demonstrated experimentally in rabbits that the duration of caloric nystagmus did not always represent the activity of the peripheral labyrinthine function.
    The duration of nystagmus due to labyrinthine disorders of one side ear (Meniere′s disease) reveals frequently a directional preponderance by caloric test. Directional preponderance which consist of prolonged duration of nystagmus to one direction by caloric stimulation of either ear does not indicate a hyperactivity of one labyrinth.
    The rabbit which has an unbalance in peripheral labyrinth function shows the spontaneous nystagmus, but it disappeares gradually by the central compensation. In these rabbits it is found that the spontaneous nystagmus is induced by an unbalance in central pathway of the labyrinth after caloric stimulation, thereby the duration of nystagmus is prolonged.
    When the cerebellum was injured, the duration of nystagmus was prolonged by caloric stimulation of peripheral labyrinth, but directional preponderance was not reverled distinctly, when theperipheral labyrinth was kept in the balance.

    With the purpose to clarify the relationship between sugar metabolism and inner ear function, the author investigated the effect of insulin on cochlearmicrophonics as well as the behavior of blood circulation and glycogen precipitation in the inner ear. Cochlear microphonics and action potentials were measured by means of vestibulotympanal recording in guinea-pigs and round window recording in cats, using pure tone and click sound. In order to know the condition of the blood flow in the inner ear, continuous registration of the veiocity of the blood and the pressure in the vertebral artery, internal carotid artery and internal jugular vein were obtained using Rein's The rmostromuhr. The venous blood sugar level was estimated by Somogyi's micro-colorimetric method.
    The intravenous injection of regular insulin caused the decrease of blood sugar level, hypotension and lowering of the body temperature. On the other hand, the blood flow in the vertebral artery increased promoting the circulation in the inner ear. The hypoglycemic condition induced by insulin injection did not depress the sensitivity of cochlear microphonics, as far as the heart was in normal function, even in the hypophysectomyzed guinea-pig. The recovery time of cochlear microphonics was not affected after the exposure to pure tone of 95 phon at 4000cps for 30 seconds, while a remarkable delay was shown after the transient cessation of breathing in the hypoglycemic animals. Determined by PAS reaction with salivary digestion, the precipitation of glycogen in the inner ear tissue was not modified by insulin injection, except in the hypophysectomyzed guinea-pig.
    In the condition of insulin hypoglycemia, the function of the inner ear was well preserved to be compensated by the increase of the blood flow in the vertebral artery. In the case of the lack of oxygen supply, however, the sugar metabolism was disturbed and the sugar reserved in the tissue was utilized. When the reserved sugar was used up, the function of the inner ear was disturbed by the hypoglycemia. The blood sugar was believed to be an indispensable factor in the maintenance of the inner ear function.

    The frequency selectivity of the ear is measured by combination of two oscillators and an electronic switch in respect to relative difference limen in the normal ears as well as in the pathological ears with perception deafness. The differen limen is greater in the ears of perception deafness that: in the normal ears. However, the individual variation of the D.L. makes obscure differential diagnosis. Only D.L. for 4000 is found available in differential diagnosis.
    The authors explain that measure of relative D.L. is not suitable representation of the frequency selectivity of the ear and that it should be replaced by another type of measure i.e. Q from the dynamical theory of resonance. Various values of Q are calculated from the relative D.L. actually obtained from the normal ears and then compared with the mechanical Q of the basilar membrane. A marked difference between the two types of Q indicates that the sharp frequency selectivity of the ear depends more exclusively upon the neural mechanism of the ear including the hearing center than the resonance mechanism of the basilar membrane.

    Clinical studies, chiefly about renal function, on 97 patients with chronic tonsillitis and tonsillar focal infection (articular rheumatism 8, acute nephritis 14, and chronic nephritis 5) were done.
    Cardiac function was studied by electrocardiogram.
    One mounth after the tonsillectomy, those renal and cardiac function were again examined.
    The results were as follows:
    (A) Impairment and recovery of the renal function
    (I) Group A; 65 cases of chronic tonsillitis without complication
    Renal function test on these caces showed impairment of RPF in 23 caces (35.4%), of GFR in 20 caces (30.8%) and of FF in 18 caces (27.7%).
    (2) Group B; 5 caces of chronic tonsillitis with the history of nephritis
    Number of renal impairment caces was 4 in RPF (80%), 3 in GFR (60%) and I in FF (20%).
    Among those 66.6% and 66.6% showed recovery.3) Group C; 8 caces of chronic tonsillitls with articular rheumatism
    Number of renal impairment caces was 4 in RPF (50%), 3 in GFR (37.5%) and 4 in FF (50%).
    Among those 75%, 100% showed recovery respectively.
    (4) Group D; 14 caces with acute nephritis
    Number of renal impairment caces was 4 in RPF (28.6%), 12 in GFR (85.7%) and 11 in FF (78.6%).
    Among those 50%, 91.7% and 90.8/ showed recovery respectively.
    One mounth after tonsillectomy, most of them recovered from acute nephritis and their GFR was markedly increased.
    (5) Group E; 5 caces with chronic nephritis
    Thcse caces were in the compensated stage of chronic nephritis, therefore only 1 cace showed impairment and recovered after tonsillectomy.
    But on the contrary, other caces which had normal function, showed following impairments after tonsillectomy; 2 caces in RPF, 1 cace in GFR and 3 caces in FF.
    (B) Impairment and recovery of the cardiac function
    Myocardial damage was demonstrated on electrocardiogram in 4 out of the 42 caces (9.4%). avated.
    (C) Local and general symptoms
    (1) From 80 to 100% of each gronp was a type of habitual tonsillitis.
    (2) The findings of the palatine tonsils were as follows:
    1) cryptic (burried), 2) abherent, 3) the surface was uneven, 4) superior tonaillar fossa was deep and filled with pus or plug, 5) local redness of anterior palatine arch, 6) swelling and pain, due to pressure of submaxillary lymph gland and 7) slight fever.
    Such symptoms were far lighter in group A than in other groups.

    1) Anesthesia and the administration of fluid during the operation: After tracheotomy, the patient is intubated and the anesthesia is given with closed circulating system. During operation heal canula is inserted to prevent aspiration pneumonia. Five hundred cc of dextran and then equal amount of blood is given intravenously during the operation.
    2) Radiation before and after the operation: Before the operation X-ray radiation is given.The radiation is done from four directions and is each direction 2000r. is given. The total amount 2000r. After the operation radium is given, average 1500mg hours.
    3) Incision and the extent of operation: When the tumor is a median type, formal extraction method is employed according to Hoshino′s incision. When the tumor is a lateral type, adding to the above, transverse incision method along the zygomatic arch is employed, and the arch and all masseter muscles are removed. When the tumor is infiltrating into the orbit, the contents of the orbit are removed. When the tumor does not infiltrate into the palate, the incisors on the affected side and the mucosa of the palate are not removed. To sum up, returning to the principle of operation, it is devised that necessary and sufficient incision and removal are to be done.
    4) For the last two and half years, 22 cases were operated and 12 of them are now alive without recurrence.

    To establish a theoretical equation of hearing restored by the tympanopiasty, hearing restored by various types of operation was examined by means of the mesurement of cochlear potential in guinea pig. The results were as follows :
    1) Data obtaineb dy the experiment were calculated by classical method of Wullstein cal equation of Schmitt and various inconsistencies were found.
    2) The new theoretical equation was established with consideration of two factors, which Schmitt entirely had neglected, i.e. difference in mobility between oval and round windows, and the action of the sound vibrating the whole skull transmitted through bone conduction upon internal ear (the equation of Maruyama & Tsuchida).
    3) The equation of Maruyama & Tsuchida is as follows:
    db=20log 43/43F-0.162d+0.215
    F : The ratio of sound pressure transformation when 1 is taken as normal.
    d: 1-D/100
    D: The ratio of sound transmission loss.
    4) Application of this theoretical equation showed no inconsistency in the analysis of experimental data.
    5) The ratio of sound pressure transformation of the artificial ear drum was conveniently expressed by the ratio of effective area.
    6) The ratio of sound pressure transformation of the artificial ear drum closely related to the shape of section lining.
    7) When a columella was placed out of the center of the membrane, the ratio of the effective area of the membrane was decreased.
    8) The thiner was a plastic membrane, the greater was the ratio of effective area; when the abdominal skin of a guinea pig was used, the thickness showed no significant influence upon the ratio. A skin had a greater ratio of effective area than a plastic membrane of the same thickness.
    9) The effect of phase shift by the ear drum upon hearing was considered almost negligible when hearing loss was below 30db.
    10) The consideration made in the experiment of guinea pig was likewise applied to the case of human tympanoplasty and a new theoretical equation was established.
    The nomograph of the equation was illustrated

    Wir haben einen klinischen Fall, 51 jahrigen Mann, des anfallsweise auftretenden Lageschwindels, der wahrend des Anfalls von dem grobschlagigen, richtungswechselnden Lagenystagmus begleitet war, berichtet.
    Es liegt eine Besonderheit, insofern es den Schwindelverlauf betrifft, daran, dassd der Schwindel dieses Falls ganz anfallig nach den symptomlosen Zwischenzeiten wiederhohlt. Aber wenn der Sitz der Meniereschen Erkrankung peripher im Labyrinth lokalisiert ist, wird die Hypothese, dass richtungswechselnder Lagenystag mus auf ein zentrales Geschehen hinweist, entkraftigt.
    Trotz dem genannten Schwindelverlaufe waren weder positive Zentralsymptome noch aktiver klnischer Befund, der die Erkrankung des periphere Labyrinths beweist, zu finden, bis auf die massige Hirnarteriosklerose.
    Demnach fallt es uns ein, dass dieser Fall eine Quelle seiner Symptome wahrscheinlich zur zentralvaskularen Disfunktion oder Veranderung fordern musste.
    Dann haben wir uber den mehreren Probleme auf die Diagnose erforscht and ferner betont, dass die Untersuchung des Lagenystagmus grosse klinische Wichtigkeiten wie die anderen hatte.

    There has been two opposite opinions about the findings of bone tissue in chronic paranasal sinusitis. Some authors consider the histological finding of the bony wall of the paranasal sinuses as pathological chronic inflammatony reaction, but the others consider it physiological. Using rabbits. tion by the following procedures, such as: various foreign bodies i.e. fragments of bone, tooth or gauze inserted into the right maxillary sinus (group 1), 2% solution of egg white albumin poured into the right maxillary sinus of the sensitized animals (group 2). The left maxillary sinuses were served as control.
    The results were as follows:
    Group 1 : In all specimens the mucous membrane of paranasal sinus showed the infiltration of inflammatory cells or the fibrosis. In the early stage, osteoclastic and ostesblastic activities were seen. In the late stage, osteoblastic activity was prominent.
    Group 2: The progress of the tissue rection was very rapid. The mucous membrane showed marked edema but no significant changes were observed in bone tissue in anystage.
    At least in chronic paranasal sinusitis with infiltrating or fibrotic type of mucosal changes, changes in the bone tissue were thought to be pathological caused by the inflammation of the mucous membrane.
