JOURNAL FREE ACCESSThis is an abstract of the special presentation read at the general meeting of Japan Broncho-esophagologrical Society in 1968.
The epithelium lining of the esophagus and the trachea of higher vertebrae (human, rabbit, rat, mouse, guibea pig, cat, chicken and pigeon) was observed with light and electron microscopy. The esophageal mucous membrane is the stratified squamous epithelium consisted of basal, spindle, granular and corneal layer. Although several authors suggested that the stratified squamous epithelium of the esophagus undergoes cornification in animals that take coarse vegetable food, the relationship between the character of cornification and nature of food needs further investigations. The fine structure of keratohyalin granules found in esophageal epithelium was described in detail and morphological character of keratin located in stratum corneum was discussed. It is interesting to note that an electron dense material similar to the keratohyalin granules which attached to tonofilament, appears along the inner leaflet of the plasma membrane, and that this material seems to make thick the plasma membrane. Origin and function of membrane-coating granules (MCG) found in esophageal epithelium were described in detail
On the other hand, lining of trachea is ciliated columnar epithelium interposed by goblet cells. The ultrastructural findings of cilia, centrioles and basal body were discussed in comparison with the function of these cell organelles. The precursor body of centriol was found in the supranuclear region or near GOLGI area of the ciliated cell. Formation of this cell organelles, however, needs furthermore studies. Numerous goblet cells were scattered throughout the epithelium and the ultrastructural findings of their four functional stages were described in detail. Furthermore, several interesting cells found in tracheal epithelium, brush cell in rat, non-ciliated endoplasmic reticulum-rich cell in mouse and bat, were observed.View full abstractDownload PDF (2456K) -
With Special References to Clinical and Experimental Studies on Regional Pulmonary CirculationMasaki Ebuchi1969 Volume 20 Issue 6 Pages 255-269

JOURNAL FREE ACCESSThe regional pulmonary circulatory function on asthmatic lungs and the various factors concerned with them were studied in 92 asthmatic patients and 28 dogs of model of asthma, using pulmonary perfusion scaning in asthmatic attack and non-attack.
1. In asthmatic attack, some regional pulmonary circulatory defects with little variety were seen in all cases and in non-attack, most of those defects were shown the improvement.
2. Those phases were proved on the pulmogram by 133Xe and the findings of scinti-camera.
3. The defects of the regional ventilatory function in attack were seen to be closely connected with the defects of regional pulmonary circulation.
4. Various abnormalities were seen in bronchi and unequal findings were found in pulmonary arterial vessels and capillaries in the model of asthma of dogs caused histamine. They were shown to identify with the findings of pulmonary scintigram.View full abstractDownload PDF (4561K) -

JOURNAL FREE ACCESSAiming at prevention of lowering of pulmonary function, we performed bronchoplasty instead of right pneumonectomy usually indicated on 2 cases of primary lung cancer. In the surgical procedure sleeve resection and anastomosis are performed at the part of the broncus between the right main bronchus and the intermediatetrunk so that the right middle and lower lobes are preserved. Case 1, 1 year and 5 months after surgery and Case 2, 1 year after surgery both have been rehabilitated already. The part of anastomosis on the both cases reveals no sign of stenosis and keeps sufficient lumen. Neither recurrence nor metastasis is present, and bronchospirometry revesls satisfactory function of the remaining lobes. Tumor was epitheloid cancer on the both cases.View full abstractDownload PDF (3822K) -

JOURNAL FREE ACCESSA 31 years old male who had post traumatic stenosis of the trachea associated with laryngeal nerve paralysis was treated by end-to-end anastomosis of the trachea In this procedure the thyro-hyoid muscles and pharyngoconstrictos were cut and the lower part of the trachea was free from the superior mediastinum before the stenotic portion of the trachea was removed and end-to-end anastomosis of the trachea was performed.
Post-operatively no swallowing difficulty was observed even under cineradiography, and the air way was still patent 2 years and 6 months after the surgery.
Aphonia was present in the early postoperative stage, but vocal function improved gradually and considerably, and at present, we can observe a good motility of the false vocal cords and the left vocal cord.
Improvement of phonetic function has been proved on cineradiogram, radiogram and electromyogram, and according to the results of these observations, the author considered the regeneration of the recurrent nerve.View full abstractDownload PDF (1466K) -

JOURNAL FREE ACCESSA case of“bronchial adenoma”was reported. A young woman, aged 24, was admitted to our clinic of Kyushu University, complaining of dyspnea and wheeze for several months.
By bronchoscopy, a round reddish tumor of the anterior wall of trachea under cricoid cartilage was found and it obstructed trachea almost completely.
After tracheotomy, a partial resection of trachea including the tumor was performed under general anesthesia.
Pathological diagnosis was “bronchial adenoma”, cylindroma type and the tumor cells had spread to the peritracheal tissue histologically. The patient is now well without recurrence over a year following surgery.
Although the adequate histological classification has not been established, “bronchial adenoma”has to be considered as a potentially malignant tumor and a radical operation should be necessary.View full abstractDownload PDF (2353K)
