摘要: 目的:探讨复发性口腔溃疡(ROU)的免疫发病机制。方法:应用CTLL法和短寿命抑制性T细胞(Ts)功能测定技术,对36例ROU患者和41例正常对照 组外周血白细胞介素2(IL-2)活性和Ts功能进行检测,并观察转移因子治疗后IL-2及Ts的 变化。结果:ROU患者外周血单个核细胞产生IL-2活性水平明显低于正常对照组(P<0.01),Ts抑制功能与正常对照组比较差异无显著性(P>0.05)。经转移因子治疗后ROU患者IL-2活性水平较治疗前明显提高(P<0.05),转移因子治疗前后ROU患者Ts功能变化差异无显著性 (P>0.05)。结论:ROU患者细胞免疫功能低下及T细胞亚群功能失衡与本病发病有关;转移因子治疗ROU可提高ROU患者IL-2活性。

Abstract: Objective To investigate the immunologic mechanism of recurrent oral ulcer(ROU). Methods The IL-2 activities and T suppressor(Ts) cell functions in peripheral blood of 36 ROU patients were detected with CTLL and short-term Ts cell functional detection technique. Results The IL-2 activity of single-nuclei cells in peripheral blood of ROU patients was lower than that in normal controls (P<0.01), while the suppressing function of Ts cells had no difference between the two groups. The IL-2 activity of ROU patients increased sifgnificantly after treated with transfer factor compared with before treatment (P<0.05), while the Ts cell function did not change after treatment(P>0.05). Conclusion The ROU patients have a low cell immune function and an imbalanced T cell sub-clone, which may be related to the development of ROU. The effect of transfer factor on ROU is closely related to its function of up-reguating IL-2 activity.
