ジャーナル フリーThe study of the effects of air pollution of the false cord and ventriculus in the glottic region of the laryngeal cavity were performed using scanning electron microscopy, in view point of the defense mechanism of the glottic region due to outer stimulation from rostoration to the irreversible stage. Results were as follows:
1) The cases of sillicosis which were exposed to long term stimulation demonstrated heavy irrevesible changes and alterations in spite of sufficient restoration periods.
2) Cases of 60Co irradiation, in particular, 3000rd, demonstrated sufficient recovery after a irradiation period of three to four weeks. 6000rd exposure however, revealed irreversible changes even after a period of irradiation lasting eight weeks.抄録全体を表示PDF形式でダウンロード (16576K) -

ジャーナル フリーRegeneration of the tracheal mucous membrane of the rats from 6 hours to 14 days after curetting the anterior and the lateral walls was investigated mainly with the electron microscope and with the autoradiography.
According to the observation the following results were obtained.
1. Regeneration of the mucous membrane from 6 to 24 hours after curetting, the mucousal epithelial cells were migrated from the basal cells of the remained membrane.
2. Since 2 days after curetting, the basal cells at the margin of wound and those migrating in the wound both were increased in number to arrange in multiple layer. The basal cells were gradually differentiated into the indifferent appearance cells and then pseudostratified ciliated columnar cells and or stratified scuamous epithelium. (escalator type)
3. In H-thimidine autoradiography, the label index of migrating basal cells was within normal limit (1%) in the first 6 hours after curetting, then began to elevate after 8 hours.
The first mitotic figure was found in the remaining mucosal epithelium after 20 hours.抄録全体を表示PDF形式でダウンロード (44624K) -

ジャーナル フリーTracheotomy is playing a very important role in daily clinic. However, inability of decannulation or closing tracheostoma is not so seldom seen. When no anatomic laryngotracheal abnormality can be demonstrated, the inability to decannulate a prolonged tracheotomiged patient may in fact be explained by the temporary loss of laryngeal abductor function. This study was carried out to see if the phasic inspiratory activity of the laryngeal abductors may be altered by tracheotomy.
Eleven dogs were used for this study. Motor action potentials of the posterior cricoarytnoid muscle were electromyographically studied while varying the resistance of the upper airway and after acute and/or chronic tracheotomy. The loss of abductor activity persists as long as air way resistance remains severely reduced. Prolonged reduction of airway resistance by, for example, tracheotomy, resulted in difficulty of reestablishment of abductor function. It seems most likely that gradual reduction of tracheotomy bore or increasing ventilatory resistance by partial cannula occlusion is very effective in restoring the phasic activity of the posterior cricoarytenoid muscle in a patient with problem of decannulation due to affected abductive movement of the vocal cord.
In fact, we had a tracheotomized patient with inability of closing the tracheostoma due to sever stridor and dyspnoea.
Laryngobronchoscopic examination revealed that there was no significant anatomical and organic abnormality but for loss of laryngeal abductor function. Supported by the present experimental data, gradual reduction of the bore of tracheostoma was carried out while careful checking blood gas values.
Finaliy, laryngeal abductor function was obtained enough to inspirate respiratory air. In this paper, this case was reported and discussed in terms of the present experimental data.抄録全体を表示PDF形式でダウンロード (3525K) -

ジャーナル フリーWe have described a new techique of transbronchial biopsy of the lung by bronchofiberscope and the use of our technique in patients with diffuse diseases of the lung. Satisfactory pulmonary tissue for histology was obtained in 38 of 41 cases (92.7%). The only complication among the 41 patients was two hemoptysis. We have found that transbronchial lung biopsy has been helpful in the diagnosis of diffuse pulmonary disease.抄録全体を表示PDF形式でダウンロード (9249K) -

ジャーナル フリーDifficulty in swallowing in the second stage may be categolized into three different types such as;
1. that due to aspiration, 2. that due to stenosis or obstruction, and
3. that due to others, for example, due to pain etc.
They can be driven by malfunction of many factors, local or central, organic or functional.
Several case reports were shown in this series and clinical entities of these various malfunctions were discussed with special refereace to Sheir pathogenesis and therapeutic standpoint.抄録全体を表示PDF形式でダウンロード (818K) -

ジャーナル フリーRecently there are many early esophageal cancer, but there are several difficulties in diagnosis of them. In X-ray studies, it is very difficult to find a small erosive esophageal cancer or dyscolouring changes of esophageal cancer. On theother hands, it is easy to find these lesions in endoscopic examinations. If endoscopic screening of esophageal lesions were aveilable, we can find more early esophageal cancer.
We tried endoscopic screening of esophageal lesion, using a flexible esophagofiberscope with small calibre. 123 patients at first visit to our hospital were performed these examinations under a superficial mucosal anaesthesia, using 4% lydocain. The esophagofiberscope, we used, had sufficient performances and we made good observations in 94.4% of all patients. In 4.6% of patients, it was difficult to make precise observations, because of reflex into the esophgus. Esophageal reflex was most prominent in patients with meals about 3 hours before. It is advisable to perform this examination on the patient with meals 4 hours before, at least. Out of 123 patients, we found 37 cases with esophageal lesions (30% of all patients); one esophageal cancer, 12 hiatus hernias, and others. There was no complications in these examinations. Patients complains little hardness or pharyngeal pain.
From these studies, we could not find early esophageal cancer, but found many benign esophageal lesions. Using the endoscopic screening of esophageal lesions, we can hope several developments in studies of esophageal diseases.抄録全体を表示PDF形式でダウンロード (1646K) -

ジャーナル フリーWe have investigated comparative dianostic radiation dose to the skin and tracheobronchial tree during thoracic fluoroscopy. The purpose of this study was to determine the extent of change in the optic glass fiber within the dose range used for this radiologic examition. Mg2SiO4 thermoluminescent dosimetry was performed during thoracic fluoroscopy using an under-tube X-ray apparatus. The following conclusions were obtained.
1) Mg2SiO4 thermoluminescent dosimetry was suitable for this study both morphologically and functionally.
2) The X-ray dose to the thoracic skin measured during fluoroscopy with the new CdZnS image-intensifying machine was 1.5 R/min. On the other hand, the dose measured using the old apparatus was 3.1 R/min.
3) The irradiation dose subjected to intra-thoracic structures were determined and compared to the skin dose. Using the skin dose as 100%, the intra-tracheal lumen mean dose was 7.3%, main stem bronchus 10.5%, lobar bronchus 16.2%, segmental bronchus 19.3% and subsegmental bronchus 19.8%.
4) One can calulate a safe exposure time for the endoscope using the following correlation. The irradiation dose to skin in 1 minute, mutiplied by three is equal to the irradiation dose to the segmental bronchus in 15 minutes.抄録全体を表示PDF形式でダウンロード (5679K) -

ジャーナル フリーOne case reports a 58 year old male who suffered from tracheal stenosis after an emergency tracheotomy due to a fracture of the cricoid cartilage after a traffic accident. Two stage operations were performed. The 1st stage operation was performed for the removal of the granulation from the front wall of the cricoid cartilage to the 3rd ring of trachea. The 2nd stage operation consisted of the plugging of the deficit area with heavy marlex. Satisfactory results were obtained even after one year from the operation.
Heavy Marlex mesh is strongly suggested as useful material for the partial reconstruction of the trachea.抄録全体を表示PDF形式でダウンロード (2786K)
