In order to study the interrelationship between the dental pulp and the periodontal tissues, acute response of the periodontal ligament (PL) blood flow to an application of histamine solution to the dental pulp and the gingival sulcus was investigated using laser Doppler velocimetry. The results were as follows:1. When histamine solution was directly applied to PL, PL blood flow increased immediately after its application. This increase disappeared after washing out the histamine.2. PL blood flow also increased after applying the histamine solution to the exposed pulp surface and the gingival sulcus, respectively. These increases did not disappear after washing out the histamine in the applied area.These results indicate that a measurement of tissue blood flow following an application of histamine solution as a tracer is methodologically useful to evaluate an inflammation spread between the tissues.

为了研究牙髓和牙周组织之间的相互关系，急性反应的牙周膜（PL）血流组胺溶液的应用于牙髓和龈沟进行了研究，使用激光多普勒测速仪。结果如下：1.当组胺溶液直接应用于PL时，PL血流量在其应用后立即增加。这种增加在洗掉组胺后消失。PL血流量也增加后，应用组胺溶液暴露的牙髓表面和龈沟，分别。这些增加并没有消失后，冲洗掉组胺在应用区域。这些结果表明，组织血流量的测量后，应用组胺溶液作为示踪剂是方法学上有用的，以评估组织之间的炎症扩散。
