涎液的主要功能之一是保护口腔组织,抵抗细菌和病毒入侵。其中,起主要作用的是免疫球蛋白IgA和IgG,IgA是主要的保护口腔粘膜的抗体。有研究表明:吸烟者涎液IgA(SIgA)水平低下,口腔粘膜易受损伤。本文对吸烟者停止吸烟2周后的SIgA水平进行了测定。 材料和方法 20位有吸烟史者,分3次复诊测定其SIgA水平;①吸烟时,②停止吸烟后7d,③停止吸烟 One of the main functions of salivary fluid is to protect oral tissues against bacterial and viral invasion. Among them, the major ones are immunoglobulin IgA and IgG, and IgA is the main antibody that protects the oral mucosa. Studies have shown that smoker salivary fluid with low levels of IgA (SIgA), oral mucosa vulnerable. This article measured the level of SIgA in smokers two weeks after stopping smoking. MATERIALS AND METHODS Twenty patients with a history of smoking had their SIgA levels determined by three referral visits; (1) when smoking, (2) stopped smoking after 7 days, (3) stopped smoking
