Results: NGF and TrkA were mainly distributed in intercalated duct, striated duct, excretory duct cells in salivary gland tissues around neoplasm, proven by pale brown positive response in cell membrane and plasm. p75 was not only found in duct epithelial cells in salivary gland tissues around neoplasm, but also apparently in serous acinus plasm.

研究发现：肿瘤周围涎腺组织中，NGF和TrkA主要分布于闰管、纹管及排泄管细胞，表现为胞膜及胞浆呈棕黄色阳性反应。p75在肿瘤周围涎腺组织中，不仅分布于导管上皮细胞，浆液性腺泡胞浆亦呈明显的阳性反应。

This result indicates that WT1 gene plays an important role in differentiation and development of fetal kidney and may be the factor that promotes metanephric blastemal cell to differentiate into epithelial cell.

结果显示小胎龄肾组织中WT1蛋白在胚基细胞和幼稚肾小球细胞核表达而大胎龄组肾组织中WT1在肾小管细胞胞浆表达，阳性率分别为57.1％(8/14)和46.2%(6/13)，提示WT1基因在胚胎肾分化发育的过程中起着重要作用，WT1蛋白可能是促进后肾胚基细胞向上皮细胞分化的调控因子，其表达在时间上和空间上都受到严格的调控，WT1的表达异常可能导致胚基细胞分化停滞。17例肾母细胞瘤WT1蛋白表达阳性率为41.2%(7/17)，阳性部位在胚基型和上皮型肿瘤细胞核，表达部位和阳性率与早期胚胎肾相似，其中间质型肾母细胞瘤均为阴性，胚基型和上皮型肾母细胞瘤阳性率70%(7/10)，两组间阳性率有显著差异。

RESULTS: After differentiation of human adherent myoblasts by neural induction medium, no cells with a neural cell morphology (ie., small, refractile cell body with dendritic cell extensions) were seen. All remaining myoblasts cultured with neural induction medium, myoblasts with proliferation medium and myotubes with differentiation medium containing 20 mL/L HS were positive for β Tubulin Ⅲ. C2C12 myoblasts were negative for β Tubulin Ⅲ. In contrast, all the above cells were negative for the markers Neurofilament Mr 68×103 and GFAP.

By the Spearman＇s correlation analysis, apoptosis of renal tubuli was positively related to Bax protein expression and negatively to Bcl-2 protein expression.

经Spearman's相关性分析，肾小管细胞Bax蛋白表达与肾小管细胞凋亡呈正相关，而Bcl-2蛋白表达则与细胞凋亡呈负相关。

Results: in contrast with model group, SSM can (1) increase the survival rate of ARF in rats, cut down Scr and BUN at 24hr, improve renal function, slightly surpass Vp in its therapeutic effect;(2) mitigate the extent of renal pathologicchanges, decrease the numbers of renal tubule necroses and casts;(3) protect renal ultrastructure such as microvilli, mitochondria, endoplasmic reticulum of TEC, podocytic process of glomerulus epithelial cell,endothelial cell etc, better than Vp;(4) enhance SOD activity, lower MDA contents in renal cortex;(5) enhance NO contents in serum, reduce ET levels in plasma;(6) evidently cut down TNF- a contents in serum, superior to Vp;(7) antagonize calcium overload in TEC;(8) alleviate renal pathological changes in ARF metaphase (at 3d), advance regeneration and recovery of TEC, restore renal structure in ARF convalescence (at 5d), and better than Vp;(9) increase the expression of TEC PCNA and prepro EGFmRNA in ARF metaphase.

Results of the experimental groups: Comparison with the control groups, in 6h and 8h groups eminences of ependymal cells with cobblestone-like appearance were seen, their microvilli were further richer, and a number of microholes could be found on their base. In body part of SFO cell membrane of some ependymal cells were broken completely, their cytoplasm was no longer seen, and cell nucleus located at one side of the cell, 5-7μm in diameter and dividing lobe-like in shape. Beside those cells some ependymal cells appeared many folds on the top of surface. In 2h and 16h groups the observation results seemed no significant differences from the corresponding control groups.
