查询词典 necroses

Under pathologicexamination, little tumor cells, obvious fibroses outside, calcifying necroses inside andapoptosis cells were found in the tumor tissue of all treatment groups, especially in I-125seeds combined with ADM group.

体内治疗实验①各实验组裸鼠均成活，阿霉素+~(125)I组肿瘤直径平均缩小至0.36cm(P＜0.05)；②白血球水平变化不明显；大体标本观察，心、肾、肝脏无明显改变。

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.

结果：与模型组相比，SSM能(1)提高ARF大鼠的存活率，降低24hr时Scr及BUN，改善肾功能，其疗效略优于维拉帕米；(2)减轻ARF肾脏病变程度，减少24hr肾小管坏死数及管腔内管型数；(3)对肾脏的超微结构如肾小管上皮细胞微绒毛、线粒体、内质网、肾小球上皮细胞足突、内皮细胞等形态结构均有一定的保护作用，其疗效略优于维拉帕米；(4)提高肾皮质SOD活性，降低MDA含量；(5)提高血清NO水平，同时降低血浆ET含量；(6)显著降低血清TNF-α的水平，疗效明显优于维拉帕米；(7)拮抗小管上皮细胞[Ca~(2+)]_i的升高；(8)使ARF中期(第3d时)肾组织病变较同期其它两组明显减轻，并使肾小管细胞再生修复提前，至ARF恢复期(第5d时)肾组织结构恢复重建良好；作用明显优于维拉帕米；(9)促进ARF中期肾小管上皮细胞PCNA的表达及EGF前体mRNA的合成，从而增加EGF的合成释放，而维拉帕米无此作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
