The Measurement of Blood Flow in Oral Soft Tissues by Regional Blood Flowmeter.

口腔内的外周循环主要取决于全身循环。然而，它本身似乎对局部刺激有反应。在提供适合活体的义齿修复治疗时，一个重要的考虑因素是从外周循环中找出义齿支持、粘膜在牙科治疗后的变化。本研究的目的是建立一种用电解局部血流计测量腭部粘膜局部血流速度的方法，并对氢气吸入方法进行改进。在本研究中，我们使用成年单凝胶犬，研究了刺激对活体的影响和心脏骤停后氢气的扩散，从而证明该方法是测量局部血流速度的更好方法。因此，该方法试图检测电解局部血流计的重现性和支持粘液…的义齿的局部血流量施压时更多。结果显示：1)在测量人的硬腭粘膜血流量时，已经认识到了区域和人的不同。但如果针在硬腭粘膜的同一点上刺入，且测量条件相同，则数据基本相同，这表明已经识别到了重现。2)在移除加压附件后24小时，3)加压附着物固定后，位于加压投影区正下方的血流立即减少，呈恒定血流趋势。4)拔除加压附着物后1周，加压加压投影点正下方的血流仍未完全恢复。5)加压附着物取出后1周，可完全识别加压加压区域外的血流。这些结果为义齿的修复治疗和后续义齿修复提供了依据。较少

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
