    Sound stimulation(256, 512, 1024 and 2048cps) was given to the fish(carassius auratus Linne) in water and hearing test was performed by observing the responses to sound, particularly the backing movement of pectoral fins.
    The response disappeared when the lower portion of the labyrinth was destructed or the swimbladder was ruptured, while the fish responded normally after the destruction of upper portion of the labyrinth, lateral-line organ and the sensory organs of the skin and the extraction of the lateral line nerve.
    Morphological studies of the fish labyrinth were performed and the remarkable findings were as follows.
    1) The whole labyrinth is found encapsulated in u semitransparent elastic membrane(Membrana propria), which histologically resembles bone tissue.
    There exists no space between the M.propria and the membranous labyrinth.
    2) The sacculus is small but has a complicated structure.The infero-medial part of the wall (bridge), which is not covered by M.propria and histologically double-layered, makes up the laterosuperior wall of the cavity, which can be reasonably called as the perilymphatic space because of its direct communication to the intracranial space.
    The sagitta is fixed to the macula sacculi at the superior and inferior edge and its wing-like process touches the bridge.
    3) Sound is transmitted from swimbladder to the sacculus via the Weberian ossicles, sinus impar and ductus communicans.
    4) The macula sacculi is more densely innervated and vascularized than the macula of the utriculus and Lagena.
    Morphologically, it seems reasonable to presume that the vibration of"bridge"be percepted by the sensory hairs of the macula sacculi.

    The labyrinthine influences on skeletal muscles were histologically studied in unilaterally labyrinthectomized frogs.
    Histological examinations of muscles of the neck and extremities were carried out on the first to thirtieth day follwing labyrinthectomy with observations of posture, body weight and labyrinthine reflexes.
    The main results obtained were as follows:
    1) Deep neck muscles contralateral to the operated labyrinth revealed histological changes such as cloudy swelling of the muscle fibers with unclear spaces in between, poor staining of the muscle fibers and sarcolemmal nuclei and plump and other irregular appearances of the sarcolemmal nuclei with obscure contents.
    2) In the deep neck muscles homolateral to the side of labyrinthectomy, no significant histological changes were demonstrated;sharply defined the muscle fibers with no swelling and most of the sarcolemmal nuclei showing normal elongated oval shapes with the prominent nucleoli.
    3) In superficial neck muscles, there were no histological changes demonstrated, neither contralateral nor homolateral to the side of labyrinthectomy.
    4) Although the histological changes were markedly demonstrated in the first to third week following labyrinthectomy, they were already seen shortly after operation and slightly reduced in fourth week.
    5) The histological changes were demonstrated in the contralateral deep neck muscles of the first to fourth intervertebral regions and they were not seen in the muscles caudal to the fourth vertebra.
    6) The muscles of the extremities, either extensor or flexors, revealed no above-mentioned histological changes on both sides following unilateral labyrinthectomy and the muscle fibers and nuclei showed quite normal appearances.
    7) Concerning the activity of succinic dehydrogenase of the neck muscles, there were no significant changes demonstrated on both sides following unilateral labyrinthectomy.
    These results apparently indicate that the labyrinthine muscle tone is not given directly to the muscles of the extremities, but that it is closely related to the deep neck muscles contralateral to the labyrinth at work.

    The author was able to produce equilibrium disturbance by infecting candida albicans in rabbits.Fifty-three rabbits were to be pretreated with dead candida before they were innoculated with alive candida.Candida was injected intravenously into the rabbits.
    The author performed the routine vestibular function test and obsrved histologically these equilibrium disturbed rabbits, and researched their etiology and pathophysiology.
    The resuits obtained were summarized as follows:
    1) Spontaneous nystagmus occured in 16 cases.
    2) Positional nystagmus occured in 33 cases.
    3) Caloric test was employed in all cases.14 cases had bilateral C.P., 24 cases unilateral C.P., 9 cases D.P., l case C.P.+D.P.and 5 cases had normal reaction.
    4) Postural reflex lowered in 25 cases.
    5) Head distorsion was found in 17 cases.
    In pathological finding, inflammatory exsuda tive changes a week after the last injection and productive changes over a month after, were found in the labyrinth and the brain of infected rabbits.
    In the labyrinth, marked changes, microabscess, hemorrhage, exsudative retention and fibrinous net were found.
    In the brain, microabscess, hemorrhage and degeneration of nervous cell were observed.Candida bodies were found in microabscess both labyrinth and brain in early stage.
    Equilibrium disturbance was mostly innoculated with labyrinthine destructive changes, however it was related withe brain changes partially.

    The developmental processes of auditory conditioned response and hearing acuity in infants under one year of age, including newborns, were studied using a combination of pure tones through a loudspeaker and electric shocks of alternating current given on the left calf.An auditory screening test by observing unconditioned auditory responses to various noises was first established to select subjects with normal hearing.Some preliminary experiments were performed in order to establish this conditioned avoidance response audiometry.
    The results obtained are as follows:Most of the infants, except some one less than 2 months old, gave definite unconditioned responses to the pure tone of 500c.p.s.at 90db.All infants could be conditioned with a combination of pure tones and electric shocks.There were observed some difference in the acquisition, extinction and generalization of the conditioned response in infants of6-9 months old, particularly in infants of 6months old.Hearing acuity rose gradually with the increase of age.There were no great difference in hearing acuity in infants from 4 to 11 months of age. In conclusion, this conditioned avoidance res ponse audiometry is useful for evaluating hearing acuity in infants less than one year old.

    Gunma district is one of the regions which have high morbidity of atrophic rhinttis in Japan.
    About 7500 students of ages from 4 to 20 years in Gunma Prefecture were examined rhinologically, and following results were obtained.
    In this region, atrophic changes in the nasal cavity with or without discharge were frequently seen, and the incidences of nasal atrophy with discharge(atrophic rhinitis) were 9.8% in males and 11.0% in females, and the incidences of nasal atrophy without discharge were 15.8% and 20.0%.
    The incidences of atrophic rhinitis and of nasal atrophy in females were higher than in males, on the contrary the incidences of hypertrophic and simple chronic rhinitis were higher in males, and sinusitis and sinusitis with atrophy were equally seen in males and females.
    Chronic rhinitis and atrophic rhinitis accompanied with nasal discharge decreased with age, and normal nose increased.
    Extreme atrophy with rudimentary turbinates was found in 7 cases, but no crust and fetor was seen in children.
    The cases of nasal atrophy without discharge were more frequently seen in mountain village than in city, however the differrence between village and city in the incidence of atrophic rhinitis accompanied with purulent discharge was not significant.

    Twenty-eight-years-old house wife diagnosed ophthalmologically as left optic atrophy with apex syndrome had been treated conservatively about 40 days in an university hospital, but v.s. rsened nil.On August 30, 1965, she was hospitalized in NIHO-Institute.Rhinological Diagnosis was chronic bilateral odontogenic sinusitis and left rhinogenic retrobulbar optic neuritis.
    Pansinectomy of both sides, removal of 2 and decompression of the left optic canal by the transethmoidal route were performed.
    Grades of the inflammation of sinuses were as follows:Left side:Maxillar cavity:severe.
    Frontal sinus:severe.Posterior ethmoid:mild.
    Only the most posterior ethmoid near the optic canal:severe.Sphenoidal sinus was not found.
    Right side:Maxillar cavity:severe.Ethmoid: severe.Frontal sinus:mild.Sphenoidal sinus was very big, and developed to the left optic canal, and its inflammation was severest.
    In the specimens of the mucous membrane of the right sphenoidal sinus obtained during the operation many big bony sequestrums were found.
    Route to the optic canal of the development of the inflammation was confirmed as follows:2, maxillar sinusitis, ethmoiditis, sphenoidal sinusitis of the right side and then the left optic canal, were involved.

    For the purpose of selecting the suitable operative methods and establishing the best therapeutic policy, it seems more reasonable to classify the carcinoma of the maxilla by the degree of extension rather than the direction of extension of the tumor.The degree of extension was expressed as circumscribed(T1), relatively circumscribed (T2), extensive(T3) and superextensive(T4) as in
    TNM classification.Taking the metastasis into consideration, four stages(Stage I_??_IV) were determined.To make the classification easily understandable and precise, a schematic figuer was used instead of verbal description to show the border of extension to the highly complicated surrounding structures. 233 cases of carcinoma of the maxilla treated by us during 1957_??_1964 were thus classified, and the crude survival rates were compared.When treated in our routine combined method, the rate for Stage I_??_II and Stage III were high.The former, when treated with radiation alone, showed the relatively satisfactory.When the Stage III was treated with radiation alone, the rate was as poorly as for the Stage IV.

    Concerning on the classification of carcinoma of the paranasal sinuses, that was determeined at the 8th International Oto-Rhino-Laryngological
    Congress, we made our latest proposal to the classification.
    T1:Tumor without bone diestruction localis in the maqillary or ethmoid sinus.
    T2:Tumor with minimal infiltration in the surrounding tissue.The bone destruction of the posterior wall is strictly and the invasion into the nasal cavity is generously taken into consideration, respectively.
    T3:Tumor with deep infiltration in other anatomical structures.Radical operation is possible when combined with the exenteration of orbital content, the resection of masseter and the removal of face skin.
    T4:Tumor with inoperatively extensive infil tration, such as the base of the skull, contralateral side or the epipharynx.
    The borderplane between the degrees of extension were shown by the schematic figure as the our old classification. 163 patients, who were treated in our hospital during the period of 1957 to 1962 were classified in regard to the stages derived by various classification and the modes of treatment and the 3 year crude survival rates were reviwed.
    In conclution, the difference between the stages were shown most remarkable by our latest classification of carcinoma of the maxillary and ethomoid sinuses.The result suggests the rationality of our classification and our mode of the treatment.

    Recent advancement of neck dissection made the field of operation wider into larger vessels of the neck.Otolaryngologists are now paying more attention to biological influences exercised by the suspension of the common carotid artery circulation, in particular.
    The author used the canulating type Electromagnetic flow meter to measure and recorded quantitatively the experiment dog's blood flow of the common carotid artery and vertebral artery respectively, and observed * quantitative change of arterial circulation following the occlusion of the jugular vein and common carotid artery.
    These are to dynamically clarify the effect to be brought about by vessels thus processed upon the cerebral circulation from the side of blood flow amount.The results were as follows:
    1) The range of the common carotid artery flow was 26_??_72 m.l./min with the average of 52 m.l./min in 16 dogs.
    2) In 7 dogs, the range of the vertebral artery flow was 6_??_36 m.l./min with the average of 21 m.1/min.
    3) So far as acute experimental cases concerned, either unilateral or bilateral occlusion of the external jugular veins did not cause any change in the common carotid raterial flow.
    4) The unilateral occlusion of the common carotid artery caused a rapid increase of about 50% on an average in arterial flow of the contralateral common carotid artery.
    5) The right vertebral artery had on an average 55% increase of blood flow by the occlusion of the ipsilateral common carotid artery, but little change of the flow by the occlusion of the contralateral common carotid artery.The left vertebral artery had an about 9% increased flow after the occlusion of either the ipsilateral or the contralateral common carotid artery.
    6) Summarizing the above results, in the case of unilateral occlusion of the carotid artery, the involved loss of blood flow is supposed to be compensated by 60_??_80% through the contralateral common carotid artery and vertebral arteries(the rate of the vertebral arterial flow is assumed to be 1/2 of that of the common carotid artery), and the overall loss of the blood-flow would be minimized.
    7) In the case of unilateral ligation of the common carotid artery, the compensatory capacity of increase of blood flow, quantitatively speaking, is greater in the contralateral common carotid artery than in the vertebral arteries.From this fact we can infer that in regard to the function of peripheral collateral circulations, the right and left lateral circulation is better than the anteriorposterior collateral circulation.
    8) The elevation of systemic blood pressure caused by the ligation of the common carotid artery has only a secondary significance in the compensatory mechanism of increasing blood-flow at the carotid arterial system.

    The changes in the average evoked response in human EEG to pure tone burst were studied of its latency, amplitude, wave form and rate of appearance in different anesthetic levels.
    Pentberbiturate sodium(Mintal) was injected by 5mg/kg either intramusculary or intravenously to 12 subjects, ranging in age from 6 to 24 years.
    The evoked response was lead from the needle electrode on the vertex and the depth of anesthesia was determined from the pattern of EEG in frontal lead.
    The depth of anesthesia was divided into the following five stages accorcing to the pattern of
    EEG:first stage, high voltage fast activity;second stage, low voltage fast activity;third stage, slow wave superimposed with low voltage fast activity; fourth stage, slow wave;fifth stage, patterns observed during lightening depth of anestesia.Those four stages from first stage to fourth stage were generally observed during increasing depth of anesthesia.
    During the period of lightening depth of anesthesia, the pattern of EEG appeared to be so unstable that further classification was not attempted and designated as the fifth stage in the present study.
    The amplitude and rate of appearance of the evoked response showed considerable variety depending on the depth of anesthesia, while its wave form and latency appeared to be nearly the same.
    As the anesthesia deepend, the amplitude of short latency components decreased, while that of the long latency components increased.
    In the second stage, the evoked response to tone burst was most clearly observed of all the stages of anesthesia, and its amplitude was almost twice as large as that of the waking state or of the fifth stage.
    It was assumed from those data that the long latency componets differed from the short latency components in its origin and could reasonably be similar to the K-Complex.
