阿米巴肝脓肿患者血清sIL－2R水平与红细胞免疫功能相关性的研究

本文检测了３２例阿米巴肝脓肿患者的血清可溶性白细胞介素２受体（ｓＩＬ─２Ｒ）水平及红细胞免疫功能,并分析ｓＩＬ─２Ｒ与红细胞免疫功能之间的相关性。结果显示,阿米巴肝脓肿患者的ｓＩＬ─２Ｒ水平显著地高于正常对照组,而红细胞免疫功能则显著地低于正常对照组。经流式细胞仪测定,患者ＣＤ４细胞减少、ＣＤ８细胞增高,ＣＤ４／ＣＤ８比值下降。相关分析表明,血清ｓＩＬ─２Ｒ水平与红细胞Ｃ３ｂ受体花环率（ＲＢＣ─Ｃ３ｂＲＲ）呈显性负相关。阿米巴肝脓肿患者血清ｓＩＬ─２Ｒ水平的升高可能是导致患者红细胞免疫功能低下原因之一。     

Gamma-Interferon and Soluble Interleukin 2 Receptor in Tuberculous Pleural Effusion

To analysis the difference between systemic and local pleural T cell response in pulmonary tuberculosis, we analyzed interferon (IFN)-gamma and soluble interleukin-2 receptor (sIL-2R) in peripheral blood mononuclear cells (PBMC) culture supernatants and in pleural effusion (PE). We also investigated the association of pleural INF-gamma and sIL-2R levels with development of residual pleural thickening (RPT). The subjects in this study included patients with active pulmonary tuberculosis with or without PE (n = 46), those with nontuberculous PE (n = 32), and healthy tuberculin reactors (n = 20). Measurement of IFN-gamma and sIL-2R were made by ELISA. In pulmonary tuberculosis, IFN-gamma and sIL-2R concentrations in PBMC culture supernatants were lower than those of healthy tuberculin reactors (IFN-gamma; 258.4 +/-111.5 pg/mL versus 2792.5 +/-633.2 pg/mL, sIL-2R; 1465.0 +/-144.4 pg/mL versus 4777.1 +/-178.5 pg/mL, p < 0.05), whereas IFN-gamma and sIL-2R concentrations in PE were higher than those from nontuberculous pleural effusion (IFN-gamma; 1154.4 +/-252.4 pg/mL versus 292.0 +/-68.9 pg/mL, sIL-2R; 9805.2 +/-978.9 pg/mL versus 3426.7 +/-695.6 g/mL, p < 0.05). IFN-gamma and sIL-2R in PBMC culture supernatants were significantly lower in tuberculat patients with PE than those without PE, and the patients with a high value of IFN-gamma or sIL-2R in PE showed a low value of IFN-gamma or sIL-2R in PBMC culture supernatant, respectively. Patients with RPT had significantly higher IFN-gamma and sIL-2R values in their PE compared with those without RPT. These findings suggest that diminished systemic Th1 response in tuberculosis results from the accumulation of activated Th1 cell to the disease site, and that levels of IFN-gamma and sIL-2R in PE are useful posttreatment markers of RPT.     

肝舒胶囊对慢性肝炎患者免疫功能的影响

抑肽酶对体外循环围术期白介素-2 分泌细胞和可溶性受体表达的影响

目的：白介素和其受体介导的反应在免疫功能中有重要地位，我们着重观察白介素－２分泌细胞（ＩＬ－２Ｃ）和可溶性白介素－２受体（ｓＩＬ－２Ｒ）在体外循环（ＣＰＢ）中和术后的变化，以及抑肽酶对其影响。方法：２１例瓣膜替换手术患者分两组，对照组（１０例），抑肽酶组（１１例），体外循环中给２００万单位抑肽酶。结果：两组ＩＬ－２Ｃ在体外循环１０分钟时明显降低，３０分钟时明显增加，６０分钟时继续增加，术后达到高峰，术后１天和术后３天明显低于术前。ＩＬ－２Ｃ和库血应用呈负相关。两组ｓＩＬ－２Ｒ变化基本和ＩＬ－２Ｃ相似。但抑肽酶组在体外循环６０分钟时、术后即刻、术后１天、术后３天ｓＩＬ－２Ｒ的增加幅度低于对照组。抑肽酶组术后胸腔引流量明显低于对照组。结论：体外循环对ＩＬ－２Ｃ开始为刺激，术后转为抑制状态。ｓＩＬ－２Ｒ在体外循环后期和术后增加，这对免疫功能有不利影响，抑肽酶除改善凝血功能外，还可能改善白介素介导的免疫反应。

Increased Active Rosette Formation in Patients with Gastrointestinal Cancer after Enzyme Treatment of Lymphocytes In Vitro*

Summary: Increased active rosette formation in patients with gastrointestinal cancer after enzyme treatment of lymphocytes in vitro. B. A. J. Walters, J. C. Rutherford and J. R. Wall, Aust. N.Z. J. Med., 1978, 8, pp. 610–614. Total rosette forming cells (RFC) and active rosette forming cells (ARFC) were estimated in 33 patients presenting with gastrointestinal symptoms suggestive of cancer. When the 33 patients were grouped according to whether they had cancer or not, there was a distinct difference in the percentage of ARFC (P < 0001 Mann-Whitney Test); patients with cancer having much lower values (mean 11 6 ±4–5) than patients without cancer (mean 27 2 ± 3–6). Total RFC were generally lower in the cancer group (mean 54-8 ± 8-3) than the non-cancer group (mean 71-9 ± 4–5) a/though the range was greater. After treatment of the lymphocytes with papain, the percentage of ARFC increased. In the non-cancer group the levels reached a mean of 74-8 ± 1–8, indicating that the T lymphocyte population (mean 71-9 ± 4–5) was converted into cells all having high affinity receptors for sheep red blood cells (SRBC). In the cancer group, after papain treatment of the lymphocytes, the percentage of ARFC increased to levels greater than that obtained for total RFC, suggesting a contribution from the null cell population. Serum taken from these patients was shown to produce a decrease in the percentage ARFC obtained from normal, young individuals. Further, this decrease could be partially reversed by papain digestion indicating that serum from cancer patients may contain a factor that masks T     

Role of Soluble Interleukin-2 Receptor Levels in Patients with Latent Tuberculosis

Serum soluble interleukin-2 receptor (sIL-2R) serves as a marker of disease activity in patients with tuberculosis (TB). However, little is known about its role in latent TB. The aim of this study was to assess the levels of sIL-2R in patients with latent TB and correlate them with the purified protein derivate (PPD) test results. Patients with a diagnosis of latent TB were divided into three subgroups by induration size: <10 mm, 10–20 mm, >20 mm. Blood was collected for sIL-2R assay. Findings were compared to a healthy control group. The study group consisted of 44 patients (68% male) of mean ( ± SD) age 20 ± 10 years, and the control group consisted of 41 subjects (42% male) aged 31 ± 11 years. Comparison of the two groups yielded a significantly higher serum sIL-2R level in the patients (450 ± 224 U/ml vs. 374 ± 30 U/ml, p = 0.03). Mean sIL-2R levels were significantly correlated with the presence of latent TB (p = 0.03), and with purified protein derivative (PPD) subgroups: 387 ± 177 U/ml for induration size <10 mm, NS; 450 ± 238 U/ml for 10–20 mm, p = 0.04, and 605 ± 235 U/ml for >20 mm, p < 0.0001. sIL-2R assay may serve as an additional tool to estimate the extent of the immune response in patients with latent TB.
