JOURNAL FREE ACCESSA new surgical technique, the laryngoscopic procedures with the operating microscope for removal of singer's node's polyps or other benign lesions of the larynx, has been employed. Intruments invented and used for this technique include a supplemental lens attached to the conventional operating microscope, a modified direct laryngoscope through which a binocular view of the larynx can be obtained, a self-retaining chest arm attached to the larygoscope, vanious types of forceps and scissors and a small knife with a long handle.
One hundred and fifty patients with laryngeal lesions were subjected to the current study.
The advantages of microsurgery of the laryx are that 1) the lesions of the larynx are so magnified through the microscope that even minute changes invisiale to the naked eyes are well observed and meticulous procedures in the larynx are feasible, and 2) the binocular stereoscopic view of the larynx allows accurate and precise approach of the instruments to the lesion with the best focus on the forceps or knife and the lesion.
Microsurgery can be usefully applied to surgical procedures of the larynx which may be impossible by the naked eye.
Results of pre-and postoperative examinations of the patients phonation are discussed.
In an experiment, the larynx of dogs was surgically manipulated by means of microsurgery and the histological examination was carried out on the removed larynx.View full abstractDownload PDF (19719K) -

JOURNAL FREE ACCESSRelations between air pollution and its effects on the nose and throat were studied in three polluted cities and one unpolluted city in Japan. Primary school boys and girls in each city were examined with the aid of a physical examination. At the same time, we asked them some questions of diseases on the nose and throat. After all the answers were arranged by statics, it was compared with the result of physical examination. In conclusion, paranasal sinusitis, pharyngitis and laryngitis were found in very high rate in each polluted city. There is no difference in rate of rhinitis and enlarged tonsil between polluted and unpolluted citied.View full abstractDownload PDF (1203K) -
A Basic Investigation on the Esophageal Motility by Means of Intraluminal Pressure MeasurementsMasaoki Uchida1966 Volume 17 Issue 6 Pages 273-293,249

JOURNAL FREE ACCESSIntraesophageal pressure measurements by the use of electrical pressure transducer was obtained in 60 healthy adult subjects.
1) In the resting state, high pressure zone were recorded on both ends of esophagus.
These indicate Pharyngoesophageal Junction (PEJ) and Gastroesophageal Junction (GET).
2) The upper sphincter (PEJ) relaxed 0.4 second after begening of a swallow, remained relaxation 0.8 second, and then closed.
3) The speed of peristaltic wave was not constant in various parts of esophagus, its slows down in 20cm-25cm from incisors and GEJ.
4) Abnormal peristalsis is often observed. There were non-peristaltic wave a peristalsis, repetitive non-peristaltic wave and others.
5) These abnormal waves is ovserved, generally, in lower two-third of esophagus and more frequently in older subjects than younger ones.
6) The lower esophageal sphincter (GEJ) opened 2.5 second after a swallow, remained negative phase 8.0 second, and then closed.View full abstractDownload PDF (9548K) -

JOURNAL FREE ACCESSIt is well known that reconstruction of the trachea following extensive resection is safely accomplished by direct anastomosis. However, the extent of resection which still permits direct end-to-end anastomosis has remained undifined.
In order to study the limitation in length of tracheal resection, the author measured extensibility of the trachea by means of tracheography. The trachea was extended by about 7% of its initial length in a deep inspiration phase. Head and neck extension produced more increase of trachea of 14% on the average.
The author also measured maximal extensibility of corpses' resected tracheas and found that the extensibility was definitely in inverse proportion to the age. A relationship between them as follows.
Maximal Extensibility (%) =46.54-0.43×Age
Assuming that limitation in length of tracheal resection was equor to maximal extensibility minus extension in respiration, limitations ard obtained.View full abstractDownload PDF (2292K) -

JOURNAL FREE ACCESSAmmonia gas intoxication occurs very rarely, though its use has been increasing in various industries. A 43 year-old female worker in freezing plant and a 23 year-old sailor in refrigerator ship, both surviving severe acute ammonia gas intoxication, came to our clinic with chronic respiratory distress. Diagnosis was chronic laryngotracheo-bronchitis. Respiratory function test in both cases revealed marked obstruction in respiratory tract, which coincided with irreqularly narrowed lumen of the bronchial trees visualized by bronchography. Diffusion capacity in the alveoli and arterial gas contents were within normal range. These findings indicated that mucosal damage was severe in proximal part of the respiratory tract, while slight in peripheral end. This could be explained by the fact that ammonia gas has very high solubility into water and, eventually, it is absorded quickly in the mucosa of proximal part of respiratory tract.
Broncoscopy in both patients showed marked longitudinal folds in the bronchial mucosa and narrowing of the bronchial lumen on expiration.View full abstractDownload PDF (1149K) -

JOURNAL FREE ACCESSOne aspect of our research has been to investigate the relationship between bronchial obstruction and chrouic respiretory disease. Bronchial obstruction was produced in dogs, and the effects studied of verying intervals therafter using bronchoscopic roentgenologic, bacteriologic, and histologic methods. Our findings included the following.
1. Bronchoscopic changes were noted in the bronchial wall, including edema, redness and the later appearance of granulation tissue.
2. The nature and amount of mucous secreation, and the appearance and disappearance of vavious microorganismus were studied with regard to the duration of obstruction. Notably, Gramnegative rods were found to appeare only after prolorged periods of obstruction (11 weeks). Inference can be made of the effectiveness of bronchial self-toilet, with regard to mucus debris and bacteria.
Further reseach is needed to clarify there mechanismus.
3. Using the image amplifier, the foreign body reaction of the bronchial wall was studied as an influencing factor on the degree of obstruction, and the movement of the thorax and bronchial tree immediatory after insert a foreign body into the bronchus was recorded.
4. Histologic studies ware made of the bronchial foreign body recection and of the peripheral changes, such as atelectasis and emphysema.View full abstractDownload PDF (5365K) -

JOURNAL FREE ACCESSWhen 4% Lidocaine solution was used for topical anesthesia, bacteriologic examination of tracheo-bronchial secretions occasionally showed negative cultures for bacteria in spite of the demonstration of microorganisms on direct smear tests.
To see if the anesthetic solution had any effect in producing these contradictory results, experiments were carried out with pure bacterial cultures and it was found that 4% Lidocaine solution suppressed the growth of bacteria.
Therefore, in order to assure accurate results whenever secretions are taken for bacteriologic examination, one should be careful not to take specimens that might contain some of the anesthetic solution.View full abstractDownload PDF (2997K) -
