重症肌无力血清抗乙酰胆碱受体抗体和抗突角前膜抗体监测的…

用ＡＢＣ－ＥＬＩＳＡ法对５０例重症肌无力（ＭＧ）病人血清中抗乙酰胆碱受体抗体（ＡｃｈＲａｂ）和抗突触前膜抗体（ＰｒＭａｂ）进行检测，结果发现，（１）ＭＧ患者抗体总阳性３７例（阳性率７４％），其中ＡｃｈＲａｂ阳性３３例（６６％），ＰｒＭａｂ２９例（５８％），二者均显示重症患者阳性率高于轻症。（２）血清中两种抗体滴度重症患者均明显高于轻症，胸腺肿瘤ＡｃｈＲａｂ滴度明显高于胸腺增生病例，抗体滴度与胸腺病     

白细胞介素—2辅助治疗结核病疗效观察

1993年9月～1994年12月,我院用长春生物制品所的白细胞介素-2治疗结核15例,现报道如下.病例选择及治疗方法1.病例选择结核病人15例,均为男性,年龄29～42岁,肺结核4例,其中2例同时伴有腰背部软组织结核性脓肿;颈淋巴结核11例,4例合并脓肿,2例脓肿破溃.上述病例均经病理检查确诊,包括脓肿局部穿刺脓液送检;肿大淋巴结局部穿刺活检,肺结核根据胸片所示并行PPD试验阳性者.在外院均常规三联抗痨治疗半年以上,效果不佳.入我院后继续抗衡外加用基因工程白细胞介素-2免疫治疗.     

老年急性心肌梗死患者T淋巴细胞亚群与SIL—2R的检测

以间接免疫荧光法、单克隆与多克隆双抗体夹心法测定了２０例老年急性心肌梗死患者及健康老人外周血Ｔ细胞亚群、可溶性白细胞介素－２受体（ＳＩＬ－２Ｒ）的水平，发现老年急性心肌梗死组ＯＫＴ３、ＯＫＴ４、ＯＫＴ８水平显著降低，ＯＫＴ４／ＯＫＴ８与ＳＩＬ－２Ｒ水平则明显升高，提示老年急性心肌梗死患者Ｔ细胞亚群变化与ＳＩＬ－２Ｒ水平有一定关系。     

香菇多糖注射液对慢性乙型肝炎外周血单个核细胞膜IL—2受体表达的影响

The effects of lentinan on peripheral blood mononuclear cell (PBMC) expression of IL-2 receptor in patients with chronic hepatitis B in vitro and in vivo were studied. The expression percentage of IL-2 receptor in 44 patients with chronic hepatitis before treatment was 36.74 +/- 7.74, which was lower than healthy subjects, and was 48.92 +/- 3.79 after 2 months treatment of lentinan, which was approximated the normal control. PBMC from 30 patients with chronic hepatitis B were cultured in vitro with or without lentinan. The percentage of expression IL-2 receptor was 12.81 +/- 2.62 without lentinan and was 35.70 +/- 4.87 in the presence of lentinan. The concentration of lentinan stimulating expression of IL-2 receptor was between 0.2 to 200 g.ml-1. The results suggest that lentinan stimulates expression of IL-2 receptor on PBMC, which is associated with the therapeutic effectiveness of lentinan treatment.     

多囊卵巢综合征患者卵巢间质胰岛素样生长因子受体的表达

目的：探讨肥胖及非肥胖多囊卵巢综合征（ＰＣＯＳ）患者卵巢间质胰岛素样生长因子（ＩＧＦ－Ⅰ）受体基因的定量表达。方法：用逆转录基因扩增技术（ＲＴ－ＰＣＲ），检测３５例ＰＣＯＳ患者（肥胖组１５例，非肥胖组２０例）及２０例正常妇女（对照组）卵巢间质细胞ＩＧＦ－Ⅰ受体ｍＲＮＡ的表达量（灰度比值）。并对ＩＧＦ－Ⅰ受体基因ｍＲＮＡ逆转录的ｃＤＮＡ产物进行限制性内切酶酶切分析。结果：ＰＣＯＳ两组ＩＧＦ－Ⅰ受体基因的表达量显著高于对照组，ＰＣＯＳ两组灰度比值为１．１８４±０．２４０，对照组灰度比值为０．９９９±０．０８６（Ｐ＜０．００１）。非肥胖组（１．２３８±０．３８７）明显大于肥胖组（１．０５８±０．１０９，Ｐ＜０．１）。酶切分析证实，３组ＩＧＦ－Ⅰ受体基因扩增片段相同，ＰＣＯＳ两组未发现明显的碱基突变存在。结论：ＰＣＯＳ患者卵巢间质ＩＧＦ－Ⅰ受体基因呈过度表达。且ＰＣＯＳ非肥胖患者局部ＩＧＦ－Ｉ受体表达高于ＰＣＯＳ肥胖患者。
