JOURNAL FREE ACCESSA recent advance of the medical electronics enables us to measure various kinds of phenomena in vivo by electrical devices. Changes in physical parameters such as air flow, volume, temperature or pressure are picked up by detectors and transformed into electrical signals by transducers. Today electrical instruments can almost completely amplify and record these signals. We, however, are still confronted with misuse beyond limitations of the transducers. We should use measuring devices within their functional limits. Moreover, the obtained results should be dealt with at the level of the transducers. This is explained by comparing to a stereo system which consists of a pickup, amplifier and speaker. Reproduced sound depends entirely on the worst part of the three.View full abstractDownload PDF (1338K) -

JOURNAL FREE ACCESSIn an attempt to determine if the occurrence of an attack of Ménière's disease is definitely influenced by meteorological phenomena, an epidemiological survey was conducted in 4 cities in the north-eastern and south-western regions of Japan, namely Sapporo, Tachikawa, Gifu and Fukuoka.
The subjects involved in this study were 64 patients with Meniere's disease who had a vertiginous attack during a 1-month period from April 1 through April 30, 1977 and then visited any of 6 participating hospitals in the above-mentioned 4 cities by May 10 of the same year. Included in the study subjects were only those who could state exactly the date and the time of the day of occurrence of the attack and who, at the time of examination, demonstrated nystagmus or deviation of labyrinthine origin in addition to progression of hearing impairment.
On April 12 the vertiginous attack was noted to have struck all the 4 regions ; on April 1, 6, 9 and 16 the attack occurred in 3 of the 4 regions. On all these days there was a large trough of atmospheric pressure over the most part of the Japanese Islands. Conversely, on April 2, 18, 23, 29 and 30 on which all the 4 regions were attack-free the Japanese nation, for the most part, was under a high atmospheric pressure.
These findings led to the conclusion that the attack of Ménière's disease is apt to occur when barometric pressure is low, while it is of rather infrequent occurrence in the presence of a high barometric pressure. This is supported by mean atmospheric pressure chart.View full abstractDownload PDF (1280K) -

JOURNAL FREE ACCESSA 24-year-old man was admitted to the Toranomon Hospital in June, 1977 because of intermittent watery nasal discharge. A left “nasal polyp” had been removed when he was 12 years old. From that time there were intermittent drainage of clear colorless fluid from the left nostril and two bouts of meningitis. On intranasal inspection there was a soft reddish mass on the nasal septum in the left antero-superior nasal fossa. When the patient held his head downward there was a clear watery discharge from the left nostril.
Chemical analysis of the fluid revealed a sugar content of 64 mg. per 100 cc. Frontal tomogram of the facial bone showed bone defect of the left cribriform plate. R. I. cisternography showed C. S. F. rhinorrhea from the left anterior fossa.
A intracranial operation was performed through a bilateral craniotomy. A 4 mm. fistula and a defect of the dura mata were disclosed in the left cribriform plate. These were repaired without contamination. Postoperative course was uneventful and there has been no further nasal discharge. After the operation nasal mass was removed intranasally. Microscopic examination of the tissue showed brain tissue.
Intranasal excision or puncture of transethmoidal encephalomeningocele ought to be avoided.View full abstractDownload PDF (11830K) -

JOURNAL FREE ACCESSA case of tumor-forming amyloidosis was reported. A 46 year-old male patient with a mass of the soft palate, approximately 2X3 cm. in size, was surgically treated in our clinic. At first sight the mass was suspected as a tumor of the minor salivary gland since solitary amyloidosis of the soft palate had rarely been reported. The postoperative diagnosis was histologically established by Congo-Red stainning. The case was regarded as tnmor-forming amyloidosis because of no evidence of amyloid deposition in other organs.View full abstractDownload PDF (2693K) -
Heterotransplantation in “Nude” Thymusless MiceTadashi NAKASHIMA, Kazumi MAKISHIMA, Ikuichiro HIROTO1978 Volume 24 Issue 6 Pages 969-973

JOURNAL FREE ACCESSSuspension-type cultured cells (MC cells) derived in our laboratory in 1976 from human carcinoma of the maxillary sinus (squamous cell carcinoma) were transfered to five congenitally athymic mouse mutants,“nude”, at doses of 107 cells. Tumor formation was found locally at the site of inoculation within 10 days in every case with no distant metastases. The tumors grew rapidly and constantly and continued to grow until death (within 39 days) of the hosts. Histopathological examination of the transplanted tumors revealed the proliferation of malignant cells and shows similarity to that of the human donor material. It could be concluded, therefore, that the cultured cell, used in our study, is a established cell line of human carcinoma of the maxillary sinus.View full abstractDownload PDF (7480K) -

JOURNAL FREE ACCESSIt seems to be a rule in anatomy that the vascular network of a given organ presents a pattern adequate to the function of the organ. The vocal fold has a specific layered structure which is adequate to vibration. The purpose of this paper was to investigate the vascular network of the vocal fold from a view point of phonatory function.
Radio opaque medium was injected via the bilateral common carotid artery in the laryngeal vessels of canines. After the larynx was excised and fixed, Softex contact microradiography was performed on specimens which were cut in a sagittal, horizontal or frontal plane.
For observations of the most peripheral capillaries, Indian ink was injected in the vessels and the specimens were examined under a microscope. Although these techniques work the best with living aminals, Softex contact micrography was applied also to some larynges of human cadavers.
The most significant finding was the fact that the blood vessels of the mucosa around the edge of the vocal fold are clearly seperated from those of the muscle. They come in almost exclusively from either the anterior or the posterior ends of the vocal fold. Only in the posterior part of the human vocal fold, there are some vessels which come in the mucosa from those of the underlying structure. Furthermore, there are many direct anastomoses of arterioles and venoles in the mucosa around the edge of the vocal fold. These patterns of the vessels of the mucosa around the edge are very specific to this area which moves most markedly during vibration.View full abstractDownload PDF (20769K) -

JOURNAL FREE ACCESSNeuroleptanalgesia (NLA) without endtracheal intubation is recommended as one of the anesthesia for endoscopic microsurgery of larynx that stands presently an important situation in phonosurgery. The indications are as follows: (1) cases in which phonatory function should be examined during surgery, and (2) cases in which operation is done at the cartilagenous portion of the glottis. The administration of oxygen from one to two l/min prior to the operation should be recommended, because NLA is apt to cause respiratory acidosis and hypoxic influences to the cardiovascular system.
Two types of influences upon cardiovascular function can occur when a laryngoscope is inserted: a suppresive and accelerative effects to the heart. In the former case an increase in pulse rate, mean arterial pressure and left ventricular ejection index are presumably caused by pain and pressure of epiglottis. In the latter case a decrease in pulse rate, left ventricular ejection index, a transient drop of mean arterial pressure and an increase in central venous pressure chiefly result from vago-vagal reflex. It seems that anesthesia which we have done is very desirable to both surgeons and patients, because no seriously anesthetic complications were experienced and 75% of the cases were operated with facility by surgeons, in addition 94% of the patients were satisfied with our anesthesia. Therefore, NLA without intubation is considered to be a safe and appropriate modality of anesthesia for endoscopic microsurgery of larynx if it is carefully performed.View full abstractDownload PDF (3116K) -

JOURNAL FREE ACCESSA study team was organized comprising five university hospitals in order to critically evaluate effectiveness of a medicine for treatment of sudden deafness. Neuquinon, a coenzyme Q10 preparation, was given to 154 patients who visited the hospitals soon after the onset of sudden deafness.
Effectiveness was evaluated in terms of days after the onset and degrees of hearing loss, by comparing with effectiveness of other medicines, already scrutinized, as controls. As a result, it was found that the medicine was effective to patients who came to us within 10 days after the onset with or without steroid therapy. It is significant to use Neuquinon as a first choice of treatment of sudden deafness.View full abstractDownload PDF (2127K) -

JOURNAL FREE ACCESSThe clinical trial of isoproterenol (Isomenyl (R)), β-stimulant, on the peripheral vertigo was performed by the double blind technique. Diphenidol, which is recognized the effect on the vestibular vertigo, was used as active placebo. The subjects were 63 cases diagnosed peripheral vertigo, of which 7 cases were drop-outs and exculsion, and were divided into 3 groups (inner ear vertigo, Meniere's disease, others).
Total and each group were evaluated after 2 weeks administration. Isoproterenol on inner ear vertigo was statistically more effective against nausea and vomiting, and general improvement. Effects against other symptoms and signs were no significant difference between isoproterenol and diphenidol. Side effects of isoproterenol were few. These results show that isoproterenol is effective and safe on peripheral vertigo.View full abstractDownload PDF (1248K)
