肾小球硬化是多种原因引起肾小球损伤后出现的共同转归，是慢性肾功能衰竭的主要病理基矗近年来，随着对肾小球硬化机制认识的不断深入，肾小球系膜细胞、细胞外基质及各种细胞因子在肾功能进行性减退过程中所起的作用倍受关注。

In order to investigate the role of ICAM-1 and VCAM-1 in the pathogenesis of glomerulonephritis, ICAM-1 and VCAM-1 expression were evaluated from both protein and gene level by in vivo and in vitro study, We have conducted (1) immunocytochemical analysis and in situ hybridization to examine the alteration in expression of ICAM-1 and it's relationship with interstitial infiltrating cells and TNFα; A total of 64 renal biopsies were classified in three groups according to the degree of cellular proliferation and infiltration in glomerulus;(2) indirect immunofluoresence and immunoblotting. methods to detect the VCAM-1 level both in renal tissue and in serum from the patients of lupus nephritis (17cases) and crescentic nephritis (4 cases);(3) Cell ELISA and northern blot technique to study the effects of TNFα and IL-1β on ICAM-1 and VCAM-1 surface expression and gene expression by cultured human mesangial cells .

为了探讨ICAM-1和VCAM-1在肾小球疾病中的作用，本文从蛋白质和基因两个水平，整体（研究ICAM-1时根据肾小球内细胞增生和浸润程度，将64例病人分为A.B.C三组）和细胞培养两个方面，做了如下工作，（1）利用免疫细胞化学和原位杂交技术观察了ICAM-1在64例肾小球疾病患者中的表达及其与间质浸润细胞、TNFα之间的关系；（2）利用间接免疫荧光和膜免疫印迹方法检测了VCAM-1在17例狼疮肾炎和4例新月体肾炎病人肾组织及血清中的表达；（3）利用细胞ELISA和Northern杂交技术研究了IL-1β或TNFα对体外培养的人肾小球系膜细胞ICAM-1和／或VCAM-1表面表达及mRNA表达的调节作用。

Hemorheology was determined in 55 cases of hematuria (30 cases of glomerulose hema- turia and 25 cases of nonglomerulose hematuria).

观察55例血尿病人（其中肾小球性血尿30例，非肾小球性血尿25例）的血液流变学的指标，结果表明肾小球性血尿和非肾小球性血尿有显著差异（P＜0.01）。

In order to distinguish the type of GFP positive cells in glomeruli further, we also carried out fluorescence histochemistry double staining, the results of it were: the GFP positive cells in recipients glomeruli in mice of the four, five, six groups were blood cells in glomeruli capillary loop, but not the glomeruli resident cells, for example, endothelial cells, epithelial cells or intercapillary cells.

为了进一步鉴别受体鼠肾小球内GFP阳性细胞的种类，我们进行了免疫荧光组织化学双染色，结果显示：④、⑤、⑥组受体鼠肾小球内的GFP阳性细胞可能是肾小球毛细血管袢内的血细胞而非肾小球的固有细胞，即内皮细胞、上皮细胞或系膜细胞。

All rats were killed twelve weeks later, the right kidneies were used for observing pathological change, and the expression of MCP-1 in nephridial tissue were detected by immunohistochemical method. Results (1) Change of morphology: the structure of renal tubule was normal in control group, most glomcruluses were segmented sclerosis in GS group, the renal lesions in valsartan group was minorer than this in GS group.

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
