Massive dosage alinamin F (thiamine tetrahydrof uryl sulfide) therapy (150mg/day) was performed on 267 ears suffering from various type of perceptive deafness. Therapeutic effect was found in 34.5% of the series. It must be emphasized that the earlier the patient began to undergo this treatment, the more favorable result was obtained. 79.2% of the patients who began to undergo the treatmant within one week from the onset of the disease proved effective, and in the cases that were treated within one month from the beginning of deafness 74.3% benefited from the treatment. To our regret, nearly half of the series had began to undergo the treatment in more than half years from the onset of deafness with satisfactory result only in less than 30% of them.The therapeutic effect was most markedly observed when the treatment was continued during two or three months.

Physiological properties of the pharyngeal constrictor muscles were investigated by an electromyogram. The adult dogs were carefully anesthetized under neuroleptoanalgesia. Bipolar hooked wire electrodes were inserted into upper and lower portion of the hyopharyngeal, thyropharyngeal and cricopharyngeal muscle.The contraction of the middle pharyngeal constrictor muscles showed a regularity of phasic pattern in fashion sinchronized with expiration. However the cricopharyngeal muscle burst unconcerned with respiration.The contraction of the cricopharyngeal muscle was transitorily inhibited on swallowing. The bursts of the hyopharyngeal muscle were synchronized with thyropharyngeal muscle contracted simultaneously.Bursts of the upper portion of the thyropharyngeal muscle preceded to the bursts of lower portion with a time lag of 200 msec, which meant us occurence of peristaltic movements.

The middle and inferior pharyngeal constrictor muscles which are composed of the hyopharyngeal, thyropharyngeal and the cricopharyngeal muscle directly act and convey the bolus from the pharynx to the cervical esophagus. These muscles spread over the midposterior of the thyroid and cricoid cartilage like belts, and act like peristaltic movement of the visceral smooth muscle.Histochemical and physiological studies were done used the canine cricopharyngeal muscle just after sacrifice.Histochemical study;The fresh muscle were frozen and sectioned by cryostat The specimens were then stained by myofibrillar adenosine triphosphatase, phosphorylase, reduced nicotinamide adenine dinucleotid dehydrogenase and succinic dehydrogense. The cricopharyngeal muscle was occupied mainly by the type I fiber, whose occupational ratio was 57%. The type I fiber was recognized at the ratio of 12% in the hyopharyngeal, 20% in the thyropharyngeal, and 16% in the cervical esophageal muscle.Mechanogram:The muscle specimen was diluted by the modified Krebs solution aerated by 95% O2. The cricopharyngeal muscle was then electrically stimmulated by 0.5 msec duration rectangular impulse. Time to reach peak tension in single twitch was 380 msec in the cricopharyngeal muscle and 70 msec in the brachial muscle. The cricopharyngeal muscle was easily fused by 10Hz stimmulation, and formed the complete tetanus. The hypoharyngeal and thyropharyngeal muscle didn't show K+-induced contracture, but the cricopharyngeal muscle partially show this contracture while 118 mMol KCI solution was diluted.Manometric study in man:A recording catheter with four openings of diaphragmatic transducers 1.5cm apart was swallowed through the nose until the lower esophagus and the recording on swallowing 2ml of water was done with the catheter withdrawn. The sequences of study were done aiming to the pressure change, first, on swallowing at the level of the nasopharynx, oropharynx, hypopharynx and upper most of the esophagus, and secondarily, of dynamic propelling force to convey the bolus ahead in the esophagus. It was an interesting result that there was a physiological low pressure zone around the vallecula of the pharynx. This result reflects the phenomenon that patient complaining of mild dysphagia remains the rest of barium at the vallecula on esophagography. Force to withdow the ball from the esophagus was stronger in male than in female, and at the level of the cricopharyngeal muscle, strain gauge showed the force of 700g in male and 400g in female.

A new surgical technique was deviced in order to prevent the stricture of the permanent tracheostoma. This procedure is composed of two principles ; that is, to avoid the damage of the cartilage at the entrance of the trachea and to cover the margin of the tracheal mucosa with the skin by the inverting suture with the round needle and the nylon thread.The first stage: The perichondrium of the second tracheal cartilage is stripped and then the cartilage is removed. The trachea is horizontally divided just under the inferior margin of the first tracheal cartilage and the tube is inserted into the trachea for general anesthesia.The second stage: After the total laryngectomy is performed, five inverting sutures are tied at the cartilaginous portion of the tracheal end and the margin of the skin covers the mucosal edge of the trachea. These sutures should be carefully carried out in the way which the needle must not pierce the third tracheal cartilage but only the mucosa. The interrupted suture is done at the membranedus portion of the trachea. Any cannula is not used after the surgery.
