The effects of prostaglandins and oxytocin on the contractility of detrusor muscle was investigated in the isolated detrusor muscle strips of rabbit. Contractility was measured on the Physiograph with force transducer by means of Magnus method in the Locke`s solution. The results were summarized as follows. 1. Prostaglandin E, and F2a enhanced the contractility of detrusor muscle and that was more potent in prostaglandin E2. 2. Indomethacin reduced the contractility of detrusor muscle. 3. The effects of prostaglandin E2 and F2a on the contractility of detrusor muscle was not blocked by indomethacin and atropine. 4. Oxytocin enhanced the contractility of detrusor muscle significantly and the patterns of enhancement was similar that of the prostaglandins. 5. Progesterone reduced the contractility but the estrogen didn`t affect the contractility of detrusor muscle. 6. The effect of oxytocin on the contractility of detrusor muscle was not affected by progesterone estrogen and also was not blocked by indomethacin and atropine. From the above results, it was suggested that oxytocin enhance not only the contractility of detrusor muscle but also its action was similar that of prostaglandins.

PURPOSE: To evaluate dysphagia objectively and quantitatively, and ta clarify the effect of neck position and viscosity changes in patients with aspiration and laryngeal penetration. MATERIALS AND METHODS: We studied 35 patients with dysphagia and 21 normal controls using videofluoroscopy and scintigraphy. Videofluoroscopy was performed with barium with three different viscosity, and scintigraphy was done, with water, yogurt, and steamed egg mixed with Tc-99m tin colloid. 1f aspiration was found during videofluoroscopic examination, patients neck position was changed and study repeated. Videofluoroscopy was analyzed qualitatively. We calculated 7 quantitative parameters from scintigraphy. According to the videofluoroscopic findings, we divided patients into 3 subgroups; aspiration, laryngeal penetration, and no-aspiration group. RESULTS: The result of videofluoroscopy revealed that the most cornmon finding was the delay in triggering pharyngeal swallow. Pharyrigeal transit time (PTT) and pharyngeal swallowing efficiency(PSE) in patients with aspiration were significantly different from other groups. After neck position change, aspiration could be reduced in all of 7 patients, and laryngeal penetration reduced hy about 82%. PTT ancl PSE were also improved after position change. Aspiration and laryngeal penetration occurred more frequently in thin liquid swallowing than in thick liquid and solid swallowing. CONCLUSION: PTT and PSE were useful for the evaluation of dysphagia. Aspiration and laryngeal penetration could be reduced when appropriate position assumed, We could decrease the chance of aspiration by changing the patient diet consisIency. Scintigraphy might be useful tool to quantitate and follow up these changes.
