T cell subsets of peripheral blood lymphocyte were studied in 21 splenomegalia patientswith advanced schistosomiasis japonica,24 splenectiomized patients with AS,and 20 normal persons.The results showed that the rates of CD_4￣+,CD_3￣+ and ratio of CD_4￣+/CD_8￣+were significantly decreased in both groups of patients,as compared with thecontrols.

21例晚期血吸虫病巨脾型患者和24例切脾患者、20例正常人外周血T细胞亚群检测结果表明：晚血患者两组CD_3~＋、CD_4~＋细胞百分率及CD_4~＋／CD_8~＋比值显著低于正常人（P＜0.01），巨脾组与切脾组CD_3~＋、CD_4~＋、CD_8~＋细胞百分率和CD_4~＋／CD_8~＋比值差异无显著性（P＞0.05）。

P＜0.01. 28d, q=4. 0452, p＜0.05 . Corresponding pathologic result shows that the corneal stromal of height edema increase thickness to have infiltration of inflammation cells with hyperplasia of fibroblast cell and large vessel. The collagen fiber in stromatic layer is dissolved and destroyed seriously, suggesting that in addition to HSV-1's direct destructuring effect, inflammatory cells that might play an important role in the pathology of HSK induce the immune-pathological reaction.

相应的组织病理学研究结果显示（UV-B 14天）：病毒对照组角膜基质层高度水肿、增厚，并有大量中性粒细胞等炎性细胞浸润、成纤维细胞和新生血管增生，胶原纤维肿胀、分解等，说明除HSV-1对角膜组织直接破坏外，炎性细胞介导的免疫病理反应在复发性HSK发病机理是重要的因素。

The protein had the same antigenicity as IgG, and the change of the protein had the same tendency as SHP-2, which was higher in canceration groups than in uncanceration groups and control groups in thymus cells, but there weren't significant change in bone marrow cells;⑧ The change law of the expression of SHP-1 and SHP-2 during γ-ray induced malignant transformation in BEAS-2B cell is that the expression of SHP-1 was increased synchronistically with malignant transformation of cell, and the expression of SHP-2 didn't have significant correlation with malignant transformation of cell.

癌变组胸腺细胞中SHP-2 mRNA编码PTPase催化区的700～1096bp间可能出现甲基化；⑦癌变组的胸腺细胞中存在一相对分子质量约为55×10〓的蛋白质，它与IgG具有相同的抗原性，其表达量的变化趋势与SHP-2的蛋白表达变化趋势基本一致，即在胸腺细胞中明显高于对照组及未癌变组，但在骨髓细胞中对照组高于癌变组；⑧SHP-1、SHP-2在γ射线诱发的BEAS-2B细胞恶性转化过程的变化规律：SHP-1蛋白表达量的升高与细胞的恶性转化在时间上基本一致，而SHP-2蛋白表达量与恶性转化无明显关系。

Analysis of the cells in HCC supports the presence of cells with stem-cell properties (e.g., immortality, transplantability, and resistance to therapy).

对于肝癌细胞的研究我们知道肝细胞型肝癌中的细胞具有干细胞特性，如永生性，可移植性以及对治疗手段的抵抗性。

A pure and single K+ current of ultrarapid delayed rectifier K+ current or transient outware K+ current is respectively expressed on Xenopus Oocytes. This is a moderm pharmacological model for evaluation class Ⅲ antiarrhythmiv durgs, overcomes many defcts such as lacking human fresh cardiac muscle cells as material and co-expression of many currents on cell membrane. A new compound A1998 from Ocean material is evaluated in this model for class Ⅲ antiarrhythmic functions.

Results After six passages in BHK-21 cells, cytopathic effect was observed by microscopy. The rescued virus was rejuvenated once in unweaned mice, and then came back to cell passage. We found that the poly tract of rescued virus was shortened when the virus was passaged twice in BHK-21 cells. Although the data of LD50 in mice and TCID50 in BHK-21 cells showed that the virulence and infectivity of genetic engineering viruses were lower than its parental virus, no significant difference was observed between the genetic engineering viruses with the different length poly tract.

我们发现，基因工程毒在BHK-21上连续传代至第6代时，可见明显的致细胞病变效应(cytopathic effect，CPE)；在经过一代乳鼠接种之后再重新适应到BHK-21细胞的过程中，poly区段出现了缩短现象；乳鼠致病性试验和BHK-21细胞TCID50测定结果表明，尽管基因工程毒与母本毒相比毒力偏低，但含有不同长度poly的基因工程毒之间并无显著差异。

The predacious organs of the strain are annulus and cohesive nets and the hypha which is different from the vegetative mycelium. In the cytosol there are many electro-densities which are about circular particles in different size and array on the marginal area of the hypha cell of the predacious organs, this is the important character of the fungus.

菌株的捕食器为菌环和菌网，形成捕食器的菌丝细胞结构不同于一般的营养菌丝，胞质中含有许多电子密集体，呈大小不等的黑色类圆形颗粒状，多数排列在捕食器菌丝细胞的边缘区域，这是捕食线虫性真菌捕食器菌丝细胞的一个重要特征。

2The histopathology of TMJ of PA rats showed pronounced proliferation of the synovium cells, some lytic collagenous fibers and degenerative chondrocytes in the condyles, and exudated protein and desquamating cells in the articular cavities with some fibrinous adhesions.

Results: Compared with control dogs, sections from AF dogs showed cellular hypertrophy, disarranged cell bundles and increasing connective tissue.

结果：与对照犬相比，AF犬肺静脉肌袖内心肌细胞增大、排列紊乱；细胞核大小不甚规则，核异型性明显，细胞内可见肌纤维断裂；心肌纤维之间连接组织积聚，使心肌细胞之间的间隔增宽。

A 46-year-old man presented with a gradually growing nodule on the left dorsal foot, which had been present for over 10 years. In the beginning, the lesion was treated as a keloid. Because of poor response to treatment, biopsy was arranged. Sections showed a dermal tumor composed of numerous foamy cells, hyalinized wiry collagen, spindle cells and entrapped collagen. The foamy cells were positive for KP1(CD68) and negative for S-100 protein and HMB-45. The histological and immunohistochemical results were consistent with the diagnosis of lipidized fibrous histiocytoma.

一位46岁男性从十年前开始於左足背上出现一个逐渐长大之结节，一开始被当作蟹足肿给予治疗，因为对治疗的反应不好，故安排了切片检查，病理显示一个由大量泡沫状细胞，坚硬而透明之胶原纤维，梭状细胞，胶原纤维束所构成的真皮肿瘤，免疫组织化学染色显示KP1(CD68)阳性，S-100 protein与HMB45阴性，综合病理与免疫组织化学染色结果，诊断为脂肪性纤维组织细胞瘤。
