The peripheral circulation predominat in the oral cavity depends on systemic chandes. However it appears to respond to local stimuli on its own.An important consideration in providing prosthetic treatment well-fitted to the living body is to find from the peripheral circulation how the denture supporting,mucous membrane changes following such dental treatment.The purpose of this study was to establish a way to measure the local blood flow rate in the palatal mucosa with an electrolytic regional blood flowmeter,which is improved the method by hydrogen inhalation.In this study,we have investigate using adult mongel dog,the influence of stimulation on the living body and diffusion of hydrogen gas after cardiac arrest,so that this study demonstrated that this method is better to measure the local blood flow rate. Accordingly,this method attempted to examine the reproducing capability of the electrolytic regional blood flowmeter and the local blood flow rate of the denture supporting mucous … More when giving pressure.The results showed as follow;1) In measurement of blood flow in human hard palayal mucosa,the difference of the region and the person have been recognized.But if the needle is thrusted at same point on the hard palatal mucosa and the measurement is the same condition,the data is about the same and it suggested that the reappearance had been recognized.2) At 24 hours after removed the compression attachment,a groove on the mucosa surface which was made by it was not recognized.3) The blood flow which just below the point of the region of a projection for compression was immediately decreased after set of the compression attachment.And the the tend of constant blood flow was recognized.4) At 1 week after removed the compression attachment,the blood flow which just below the point of the region of aprojection for compression was not recoveried complately.5) In the region of out of the compressive point,the blood flow was recognized complately for 1 week after the compression attachment was removed. Consequently,these results are exhibitation of the bases for the prosthetic treatment and the follow up denture. Less

口腔内主要的外周循环取决于全身的变化。然而，它似乎对局部刺激有自己的反应。在提供适合活体的义齿治疗时，一个重要的考虑因素是从外周循环中发现义齿支持的粘膜在这种牙科治疗后是如何变化的。本研究的目的是建立一种用电解局部血流仪测量腭黏膜局部血流速率的方法，该方法是对氢气吸入法的改进。在本研究中，我们利用成年杂种狗，研究了心脏骤停后刺激对活体和氢气扩散的影响，从而证明了该方法较好地测量了局部血流量。因此，本方法试图考察电解区域血流仪在加压时的再现能力和支撑黏液的义齿的局部血流速率。结果表明：1)在对人硬腭粘膜血流的测量中，已经认识到区域和人的差异。但如果针在腭硬粘膜上的同一点插入测量是相同的条件，数据大致相同，这表明已经识别了再现。2)取下压附体24小时后，黏膜表面未识别出压附体所形成的沟槽。3)在安装压缩附件后，刚好在压缩投影区域点以下的血流量立即减少。血流持续的趋势被识别出来。4)取下压迫附件1周后，压迫投影区点下方的血流未完全恢复。5)在非受压点区域，取下压附体后1周血流完全识别。因此，这些结果是义齿治疗和后续义齿的基础展示。少
