    With a purpose of collecting shortcomings of the current mastoid obliteration, we tried two methods with autgraft tissue. The one utilized the combined grafts with a bone tip from the iliac crest and the temporal muscle. The other is a new technique utilizing the temporalis osteomuscular flap.
    Major characteristics of the latter method are as follows. 1. "Living bone" is transplanted for reconstruction of the osseous external auditory meatus. Therefore, the bone is safely implanted without being absorbed. 2. This flap is not so atrophied because its vasculo-neural supply remains intact. 3. Since only the fascia for tympanic membrane is utilized as a free graft, there is a less chance of graft failures. 4. The fascia is contacted with the bone with enough blood supply, so its early take can be expected. 5. As the muscle and the bone are in a body, easier reconstruction of the auditory meatus is possible than the use of a free bone fragment.

    A case of potassium bromate intoxication showing a severe hearing loss and anuria was reported. This 19 years old female patient had no vertigo nor vestibular disorders, but a strong cochlear damage was suspected by electerochleography. In order to investigate the effects of potassium bromate on the inner ear, the authors performed experiments by using guinea pigs. At first, various concentration of potassium bromate (KBrO3) were injected through the guinea pigs peritoneum, and changes of cochlear function were tested by electrocochleography. Then, the animals were sacrified and the inner ear was observed by transmission and scanning plectron microscopy. The animals to which the dosis under 100mg/kg BW was injected, showed no remarkable changes. However, the animals, to which 100-150mg BW was given, showed the threshold elevation of 10-30dB and the following morphological findings: I) The stria vascularis was affected more severely than Corti's organ. II) Outer hair cells were impaired more severely than inner hair cells. III) Changes of hair cells were more clearly found in the upper turn of the Corti's organ than in the lower turn. IV) Changes of vestibular organ were not found. The animals to which the dosis over 150mg/kg BW was injected, showed no response in electrocochleogram and showed strong morphological changes.

    Sixty five guinea pigs were used to investigate the influence of rotatostimulation on the lateral crista ampullaris.
    After repeating the turning of cupulometric mode (terminal turning velocity of 180°/sec) for 24 or 72 hours, caloric test revealed the severer functional disorder in the lateral semicircular canal of the ampullopetal side than the ampullofugal side and most of these changes occured within 24 hours.
    On the other side, the morphological change of the crista ampullaris of ampullopetal side was compared with that of ampullofugal side by using light microscope, scanning and transmission electron microscope. In a group stimulated for 24 hours, damage was not clear and the difference between the ampullopetal side and the ampullofugal side was not observed. In a group stimulated for 72 hours, local damages were dominant in the central part of the crista which had a tendency to extend towards the planum semilunatum according to increment of changes. In this area, not only disappearance of the kinocilium but incomplete or complete loss of the stereocilia were observed. And degeneration of mitochondria was found especially in the upper part of sensory cells, but changes in the lower part of cells and nerve endings could not be found.
    These findings were more remarkable in the ampullopetal side than in the ampullofugal side, and suggested the predominant effect of ampullopetal endolymphatic flow.

    To investigate the gaze stabilization during walking, eye and head movements were analysed in 10 normal subjects who repeated stepping and running on the same spot. The following results were obtained.
    1. Head displacements during stepping were limited on both the vertical (less than 1cm) and horizontal plane (1.5cm on average). Thus, walking should be a suitable locomotion for gaze stabilization.
    2. Running induced a marked increase in the vertical displacement (5.5cm on average), which resulted in pitching motions of the head. The vertical eye movements which increased concomitantly with pitching motions of the head, seemed insufficient to maintain gaze fixation during vertical head displacements.
    3. Since the findings in the dark resembled those in the light, vision may not play an essential role to stabilize head and eye positions during walking.

    The aim of this study is to investigate characters of body sway in normal subjects of different ages and in ataxic patients, who were standing for one minute in Romberg's posture. Both mean values and standard deviations of each amplitude and each velocity of movement of the center of gravity (CG movement) were calculated by using a signal processor (7T08-Sanei). The frequency distributions were also displayed by the same way in each test subject.
    Frequency distribution curves of the amplitude or the velocity of CG movemcnt were usuallyclose to the normal distribution. Peak values of the frequency distributions were usually highand their standard deviations were small in normal subjects, whose standing posture lookedstable. However, peak values were low and their standard deviations were large in normalolder subjects or in ataxic patients, whose standing showed more unstable. That is the reasonwhy the standard deviations of both the amplitude and the velocity of CG movement are important variants to evaluate standing ability in test subjects.
    Eighty eight normal subjects (60 males and 28 females, 20 to 73 years old) and twenty three abnormal ataxic patients were examined in this study. The pathological cases were classified into three groups, such as the group of the peripheral vestibuar disease in the acute stage, the group of Meniere's disease in the chronic stage and the group of the central nervous system disturbance.
    The standard deviations of the velocity of CG movement in the anteroposterior direction were smaller in the younger normal subjects than in the elder ones. Therefore, this variant may be considered to be one of those which are influenced by aging.
    A discreminant analysis was carried out to differenciate the above mentioned three groups and the normal group. The group of the peripheral vestibular disease in the acute stage was discreminated from the normal except two cases (P<0.05). The group of the central nervous system disturbance was satisfactory discreminated from the other three groups (P<0.01). However, it was failed to discreminate the group of Meniere's disease in the chronic stage from the normal.

    We studied the following nonspecific humoral and cellular immunologicai factors in 240 patients with head and neck malignant tumor. On humoral factors; serum globulin, serum immunoglobulin, complement, CEA and serum immunosuppressive factor, on cellular factors; CellS of blood lymphocyte, percentage of T, B and IgG•FcR+T lymphocyte, skin reaction to PPD and PHA, MIF and PHA-induced lymphocyte transformation. These patients have already had abnormal immunological conditions compared with control non-malignant tumor subjects before treatment. Of humoral factors, serum α1, α2, γ globulin, complement and immunosuppressive factor were significantly elevated. Of the cellular factors, the number of blood lymphocyte was depressed. However, no significant difference was found in other factors.
    To elucidate the influence of histological character of tumor, stage of disease, age of patients and method of treatments on the immunological conditions, the patients were examined by the following five tests; serum α2 globulin, serum immunosuppressive factor, cells of blood lymphocyte, PHA skin test and PHA-induced lymphocyte transformation. 1) Patients with maxillary cancer or malignant lymphoma showed remarkably significant elevation of the humoral factors and depression of the cellular factors. 2) In the patients with advanced tumor, all humoral faceors were elevated and the cellular factors were depressed in the majority of patients. 3) Depressive tendency to the cellular factors was remarkably observed with aging. 4) Although the humoral factors were elevated, the cellular factors remained unchanged after the operation. While the humoral factors were unchanged, the cellular factors were depressed after the irradiation.
