用放免法分析牙周组织疾病唾液IgG和sIgA的变化

Analysis on the variation of IgG and sIgA in saliva in parodontitis by using radioimmunological method

采用放射免疫法检测牙周组织疾病不同状态时唾液中ＩｇＧ、ｓＩｇＡ的变化，结果表明：全部病人唾液中ｓＩｇＡ均高于正常对照组，大部分病人唾液中ＩｇＧ高于正常对照组，疾病活动期明显于静止期。为牙周病免疫学理论提供了依据。

The radio-immunology method was used to examine and analyse the changes of IgG and sIgA in the saliva samples among 144 cases and 60 normal controls in the different states of parodontitis.The results showed that the average value of sIgA of the salive sample in case groups was substantially higher than that in the corresponding control groups.The average values of IgG of the saliva sample in most case groups were higher than those in the corresponding control groups.The activity period of parodontitis was substantially longer than the static period of parodontitis.These results provided the basis for the theory on parodontitis immunology.
