Method for measuring the Flow of Saliva from the palatal Glands by Using the Iodine-Starch Reaction

本研究采用新发明的碘-淀粉反应法测定腭腺的分泌量。将用碘溶液和淀粉溶液两种溶液涂成的滤纸置于上颚粘膜表面。应用30秒后，取下滤纸，观察变色区域。不同大小的黑点在个别腺体可以准确地看到。用计算机系统对5名志愿者的变色面积进行了三次测量。三次测量面积比较，差异无统计学意义（p<0.23）。结果表明，该方法具有良好的重现性。这种新设计的方法被认为是有用的测量分泌量的腭腺和小唾液腺的功能诊断。

The purpose of this study was to measure the quantity of secretion of the palatal gland by using newly devised method applied iodine-starch reaction. A filter paper, painted with two kind of solution of iodine and starch solution, was placed on mucosal surface of the palate. After 30 sec of application, the filter paper was removed and the discolored area was observed. Various size of black spots at the individual glands could be accurately visualized. The total discolored areas of five volunteers were measured three times with computer system. The areas measured three times were compared statistically and there were no differency ( p<0.23 ). These results indicate that this application was good reproducibility.This newly devised method was considered useful for measuring the quantity of secretion of the palatal gland and as functional diagnosis of the minor salivary gland.
