Abstract］Objective:To analyse the adverse drug reaction of high dose methotrexate in treatment of childhood acute lymphoblastic extramedullary leukemia.

目的：分析比较进口与国产甲氨蝶呤在预防治疗儿童急性淋巴细胞髓外白血病过程中不良反应的发生率。

Peripheral white blood cell counts and differential WBC(eosinophil,neutrophil,basophil,lymphocyte and monocyte) counts in sheep and buffaloes experimentally infected with Fasciola gigantica were studied.

对绵羊和水牛在感染大片吸虫后外周血白细胞总数计数和白细胞分类计数(嗜酸性细胞、嗜中性细胞、嗜碱性细胞、淋巴细胞和单核细胞)的特性进行研究。

Skin stimulation test and implantation in vivo found no abscess and fistule formation. Histological section showed there was moderate inflammatory reaction of forign object exciation at the early stage of implantation. At the intermediate stage, inflammatory cells decreased, mainly including lymphocytes, and there was little inflammatory reaction and antigen reaction. Meanwhile, SIS degraded sequently. At 12 weeks, SIS was almost completely degraded and absorbed.

皮肤刺激试验和体内植入研究发现，无脓肿及瘘管形成，组织切片发现SIS植入后组织反应在早期呈现出异物刺激引起轻中度炎性反应，中期时炎症细胞减少，以淋巴细胞为主，炎症反应和抗原反应都较小，同时进行程序性的降解。12周时SIS几乎完全降解吸收。

The hematolysis rate and biologic immunocompetence of pns-5 were detected with hemolysis test and experiment of splenocyte proliferation respectively.results:the hd50 of pns-5 was bigger than 8 mg/ml and it significantly increased concanavalin a and lipopolysaccharide-stimulated splenocyte proliferation in vitro in a concentration of 0.1 μg/ml.

结果：pns-5溶血性较小，其hd50大于8 mg/ml；pns-5(0.1 μg/ml)显著促进了con a和lps诱导的小鼠脾淋巴细胞增殖反应。结论：pns-5安全性好，能促进细胞和体液免疫。

Objective To investigate the role of T-lymphocyte subsets in the recurrent herpetic stromal keratitis.

目的 研究T淋巴细胞亚群在复发性单纯疱疹病毒性基质性角膜炎（stromal keratitis，SK）中的作用。

The results provide evidence that recurrent herpetic SK represents an immunopathologic process mediated by CD＋4 T cells.

CD＋ 4 T淋巴细胞是介导复发性单纯疱疹病毒性SK免疫病理反应的主要因子。

In conclusion, acute leukemia has high heterogenicity, which could be defined as AML, but more like lymphocytic origination by morphological study. Immunophenotyping analysis could contribute to the final diagnosis of malignant cells.

急性髓系白血病细胞形态学可表现淋巴细胞样特点，结合免疫分型有助于进一步确定白血病细胞的类别分型。

Objective To research the clinical significance of ratio increase of heterotypic lymphocytes in virus-infected blood.

目的探讨病毒感染血液中异型淋巴细胞比例增高的临床意义。

Lipopolysaccharide was added to induce the ES-DC maturation.The matured ES-DC was harvested 24 hours later to identifying with morphology and transmission electron microscopy.The phenotype of matured ES-DC was analyzed by flow cytometry and compared with the immatured ES-DC.

用磷酸脂多糖促进DC的成熟，收获细胞后观察细胞形态及摄片并做扫描电镜检查，分析细胞表型并与不成熟DC细胞表型做对比，异体淋巴细胞增殖实验行功能检测。

Objective To investigate an association between CTLA-4 gone 3＇ untranslated region micro-atellite polymorphisms and IDC and to explore the immunogenetic pathogenesis of IDC.

细胞毒性T淋巴细胞相关抗原-4（cytotoxic T lymphocyte antigen-4，CTLA-4）主要在已激活的T细胞上表达，通过与CIY28竞争结合B7，抑制T细胞过度激活，维持免疫系统内环境稳定。
