Specification and verification of periodontal pathogens relate to various vascular diseases

制备了检测牙龈卟啉单胞菌和T.制备了组织标本中的局部组织。免疫组化法检测牙周病病原体在病变牙龈组织和动脉粥样硬化标本中的表达。采用聚合酶链反应方法对斯里兰卡Buerger病患者的口腔和血管标本进行牙周病原体检测。对有头颈部肿瘤病史的患者，用福尔马林固定石蜡包埋的口腔近端淋巴结进行牙周病原体检测。这些侵入牙龈组织的细菌可能通过淋巴结转移到外周动脉。

The monoclonal antibodies effective for the detection of P. gingivalis and T. forsythia localized in tissue specimens were prepared. Periodontal pathogen was detected in diseased gingival tissue and atherosclerosis sample by immunohistochemistry. Oral and vascular samples of Buerger disease patients in Sri Lanka were detected periodontal pathogens by polymerase chain reaction method. The existence of periodontal pathogens in formalin-fixed and paraffin embedded lymph nodes proximal to oral cavity was examined from patients with histories of head and neck cancer. These bacteria invaded in gingival tissues might translocate peripheral arteries via lymph nodes.
