    The electrical resistance of the basilar membrane was measured by potential drop produced by rectangular current across the partition between scala media and scala tympani and effects of anoxia, injecting of KCI solution, displacement of basilar membrane and sound stimulation on the electrical resistance was observed. These results were as follows :
    1) The electrical resistance of the basilar membrane, as effective resistance was found to be 400±900 ohms at the basal turn and using exploring electrode to exist on the level of the reticular layer in the organ of Corti.
    2) A small proportion of this resistance depends on oxygen supply. After anoxic anoxia lasting 4 minutes it decreased to 80% and in permanent anoxia this value persisted during one hour after death.
    3) By injecting isotonic KC1 solution into scala tympani the hair cell was depolarized and then the cochlear microphonics (CM) reduced markedly but the effects on the electrical resistance and on the endocochlear potential (EP) were slight.
    4) Mechanical displacement of the basilar membrane toward scala tympani by injecting Ringer's solution into perilymphatic space incresed EP, toward scala vestibuli diminished it. The change in EP (*EP) was proportional to the change of the electrical resistance.
    5) The change of EP in response to acoustic stimulation, namely summating potential (SP) was proportional to the change of the electrical resistance and both recovery of the electrical resistance and of SP after removal of acoustic stimulation showed same time course.
    6) Effects of anoxia, displacement of basilar membrane and acoustic stimulation on the electrical resistance of the Reissner's membrane could not recognized.
    7) The ratio of the change in EP (SP) to the resistance of the basilar membrane in acoustic stimulation was as same as the ratio of the change in EP (*EP) to the resistance in displacement of the basilar membrane numericaly.
    Consequently SP in response to acoustic stimulation may be caused by IR-drop of EP which was due to change in the electrical resistance of reticular layer which was produced by displacement of the basilar membrane

    In order to investigate the defence mechanism of infection of viruses in tonsils, theantibody value for influenza virus in tonsils and serum were measured and the following results were ob- tained. (Method) The hemagglutination inhibition test of Hirst was used in this experiment.
    Samples were obtained from the extracts of palatine tonsil and serum of 147 patients who had tonsillectomies. As an antigen virus A1/Omachi /1/53.A2/Adachi/2/57, and B/Setagaya/3/56 were used. 1) Nonspecific hemaggltination inhibitor was found more frequently in the tonsils than in the serum.;in cases where it was found inboth, hi- gher titer in thetonsils was found.
    2) Most of antibody values for A2 type in the tonsils were higher than the one in serum.
    3) Instudying the newer epidemics of influ- enza, ahigher value of antihody for the same type of virus was found in the tonsils.The antibody in tonsilis gradually released into the serum with time.
    4) ln comparing the group under 15 years old with one over 16 years old, the former showed higher values of hemagglutination inhibitor and higher percentage of antibody for every type of infinenza.
    In conclusion, thetonsils seemed to besigni- ficant in producing antibody for virus and especia- lly in young subjects they are considered to have an important defence function against influenza infection.

    Experiments was conducted with 35 grown-up
    dogs to resect the superior and inferior laryngeal
    nerves on one side, and observations was made for a long period on the figure of the vocal cords. At the same time, histological changes in the intrinsic laryngeal muscles of the animals was thoroughly investigated, and the following conclusions were made.
    1. From the experiments in resection in vari- ous parts of the main recurrent nerve, it was lear- ned that, in the various parts resected, no differe- nce was observed in the figure of the vocal cords after the resection. No change was noticed for six months in the position of the vocal cord on the side where the nerve was resected, and remained at all times in the paramedian position. Nor any movement was perceived in the vocal cord or in the arytenoid cartilage.
    2. As a histological change in the intrinsic laryngeal muscles of a dog more than three weeks after the resection of the recurrent nerve on one side, very conspicuous atrophy was observed in the thyro-arytenoid muscle on the resected side. The fact has been recognized that the degree of atrophy declined in the order of the posterior crico-aryten- oid muscle, and then the lateral cricoarytenoid muscle. No atrophy was noted in the anterior cricothyroid muscle, while slight atrophy appeared in the traverse part of the arytenoid muscle, not only on the resected side, but also on the side which was not resected.
    3. In cases where more than three months had elapsed since the resection of the main recur- rent nerve on one side, a compensatory movement on the normal side of the vocal cord was observed.
    4. In a dog whose anterior branch of the recurrent nerve on one side had been resected, the vocal cord on the resected side had taken the par- amedian position at the time of respiration. Ant- erior two-thirds of the glottis were opened spindle- shaped at the time of phonation, showing the form of the vocal cord similar to the clinically so-called "internusparesis" Histologically, atrophy has been observed only in the thyro-arytenoid muscle.
    5. In a dog whose inter-mediate branch of the recurrent nerve on one side was resected, the vocal cord on the resected side had taken the paramedian position at the time of respiration. Posterior one- third of the glottis on the resected side did not closed at the time of phonation, showing the form of the vocal cord similar to the clinically so-called
    " transversusparesis"Histologically, conspicuous atrophy was seen in the posterior crico-arytenoid muscle alone. Hence, in the case of dogs, this form of vocal cords is considered to be the real "post icusparesis"
    6. In a dog whose posterior branch of the recurrent nerve was resected on one side, no intri- nsic laryngeal muscle had showed atrophy. At the time of respiration, the vocal cord on the resected side was situated in the paramedian position, and higher than the opposite side, and therfore appeared to be shorter. So the vocal cord on the normal side looked slackened and paralyzed. At the time of phonation, both vocal cords closed together alm- ost at the median line.
    7. In the experiments of resection of both the internal and external branches of the superior lar- yngeal nerve, both vocal cords closed together, at the time of phonation, almost at the median line, and the movement of the arytenoid cartilage was normal. At the time of respiration, however, in the case of resection of the internal branch, slack- ening of the vocal cord on the normal side and of the slowness of movement was observed. In the case of resection of the external branch, slackening of the vocal cord on the resected side and of the movement was seen. Histologically, conspicuous atrophy was observed by the resection of the ext- ernal branch in the anterior crico-thyroid muscle.

    The existence of pollinosis in Japan has been often presumed from various points of view, but very few reports on pollinosis whose allergen is known are found so far. In 1963, in the district of Nikko and its neighbourhood, the authors hap- pened to meet 21 cases with allergic symptoms in nasal cavity, pharynx and conjunctiva, which often appear only in spring season.
    Based on various examinations, the authors confirm that these cases are pollinosis sensitized with Japanese cedar (Cryptameria japonica D. Don.) pollen. And this disease is named "Japanese Cedar Pollinosis"
    Cryptomeria japonica is a staple forest-tree and is found only in Japan. Its pollination in the vicinity of Nikko and Tokyo is seen from March to April.
    From 1963 to 1965, the total of numbers of patients reached 28 cases. The number of the patients increases most at the beginning of April, around when, the number of Japanese cedar pollens dispersed in the air increases most.
    The results investigated into allergens in these cases are as follows ; Prick test with Japanese cedar pollen showed positive results in 78.6% of the total of 28 cases. Positive intradermal reac- tions to the extract of Japanese cedar pollen (Torii Co. Ltd.) were observed in 89.3% of the total of 28 cases. Positive conjunctival and nasal reactions to Japanese cedar pollen were observed in 89.3% and 100% of the total of 28 cases respectively.
    In s cases Prausnitz-Kustner test were carried out and they showed positive results.
    In the stage of attacks, all cases showed eosi- nophilia in nasal mucus. The nasal mucosa sho- wed swelled ciliated epithelium and abundant goblet cells. There is subepithelial oedema and eosinophi infiltration.

    Juvenile angiofibroma originating from the right maxillary sinus was found in a 16-year-old boy, whose chief complaints were the swelling of right side cheek and frequent epistaxis.
    The patient was admitted on Sept. 3, 1964, and exploratory maxillotomy was done. The diag- nosis was decided with surgical findings and his- tological examination.
    Radical extirpation of the tumor was performed successfully under general anesthesia with hypo- thermia 2 months later after the first operation. Postoperatively he has been free from above com- plaints.
    Juvenile angiofibroma in the paranasal sinus is rare and only a few cases have been reported in the literature. The relationship between this case and juvenile nasopharyngeal angiofibroma and its surgical management were discussed.
    The authors stressed that the treatment of this tumor should be carried out surgically under the careful control of general condition of the patient.

    A case of neurinoma of cervical sympathetic origin was reported. A 16 year-old girl presentedherself with chief complaint of snoring of 9 month duration. Physical examination revealed a large bulging in the right lateral meso-hypopharyngeal wall, obscuring good visualization of the laryngeal lumen.
    Bimanual palpation showed the tumor extending deeply into the submaxillary triangle. Throughan external incision., the tumor was found in the parapharyngeal space and removed with the capsule. The tumor measured 4_??_7=3.5cm in dimensions and weighd 31gm. Histpathology of the tumor was reported as neurinoma.
    Postoperative course was uneventful but the patient developed Horner's syndrome. The authors made some comments on neurinoma in the head and neck region with reference to previous literatures.

    A 13-year-old boy came to hospital on Septe- mber 12, 1963 complaining of fever, headache, nausea and vomitting.
    Upon examination, his left eyelid was swollen rigidity of the neck and the pathologic reflex was positive. Lumbar puncture revealed the cloudy spinal fluid, the pressure of 200mm (water), and the cell count 270/3.
    In the Ist operation, the dura was seen to be exposed on the posterior wall of his left frontal sinus. When this was cut, greyish pus oozed out, and was washed out Energetic chemotherapy, and continuous drainage of the cisterna lumbalis was carried out. He, however, continued to have fever, and the 2nd operation was performed on September 18. Purulent fluid accumulated in the middle cra- nial fossa. The patient returned to nearly normal condition for a time, but on November, he was affected with occaisional convulsions and the motor aphasia gradually turned to sensory.
    It was suspected, therefore, that the cerebral abscess was the cause, and his angiogram was sur- veyed on March 19, 1964 with a result that a space occupying view was seen on the left-parieto- temporal region.
    Craniotomy was under-taken and an abscess the size of an egg was seen directly under the dura, and was diagnosed as subdural abscess.
    Subsequent improvemeut of the patient's cond- ition was seen, and is at present physically fit, except for slightly noticeable intelligence degen- eracy.

    The author observed the abnormal auditory adaptation by using subthreshold stimulus in the subjects with perceptive hearing loss, in which the threshold of the continuous tone was more increased than that of the interrupted tone in fixed rfequency Bekesy audiometry.
    The experimental procedures were as follows :
    1. The measurement of audible time, when the stimulus with the various intensities below the threshold of the continuous tone was presented separately.
    2. The changes of the threshold of the conti- nuous tone was observed by using the following different subthreshold auditory stimuli.
    i. The continuous tone stimuli with increas-
    ing velocity rate of intensity (5, 2, ldb/sec) in
    Bekesy audiometry.
    ii. The continuous tone stimuli started at
    the intensities of 0db SL, 10db below the inter-
    rupted tone threshold and 4db below the inter-
    rupted.
    The following results were obtained:
    1. The subjects was audible for certain se- conds, when the mild intensity below the conti- nuous tone threshold was given separately.
    2. No influence on the continuous tone threshold was noticed by using the steady increasing sub- threshold stimuli with increasing velocity rate of intensity (5, 2, ldb/sec).
    3, No influence on the threshold of the conti- nuous tone was found by using the steady increasing subthreshold stimuli started at the intensity of Odb SL, 10db below the interrupted tone threshold and 4db below the interrupted.
    According to these results, the author concluded that in these subjects the gap between the thre- sholds of the continuous and interrupted tone might be the marked abnormal adaptation resulted from steady increasing subthreshold stimulus.
