存活率

The modified rat laryngeal transplantation model improves survival rate of allograft and vessels patency rate, compared with those of Strome model.

Methods Eighty Class Ⅱ isogeneic F344 rats, weighing 250-350 g, were randomly divided into 2 groups(n=40). The control group adopted the Strome model. The allograft used for the experimental group preserved ascending pharyngeal artery, which formed a complex allograft together with tongue base, larynx and pharyngolarynx. End-to-end anastomosis was performed between both allograft common carotid arteries and anterior neck veins. The patency rate and survival rate of the allograft of the 2 groups were compared.

80只Ⅱ级近交系F344大白鼠，体质量250~350 g，随机分为2组，每组40只，共20对对照组采用Strome喉移植模型，实验组在切取供体喉时保留咽升动脉，将舌根、喉、喉咽作为复合移植体，供体大鼠双侧颈蓉动脉分别与受体大鼠颈总动脉、颈前静脉进行端端吻合重建移植喉血液循环，比较两组术后动静脉通畅率及移植喉存活率。

Methods On the basis of the previous two-cuff-technique, 120 cases of rat orthotopic liver transplantation were performed with modification of fast resecting the donor liver, two-stitch suturing suprahepatic inferior vena cavum and stoping bleeding with hot pin and so on.

120只大鼠行原位肝移植，在原二袖套法基础上改进切取供肝方法，二针法缝合供、受体肝上下腔静脉，出血点行热止血。结果大鼠原位肝移植手术时间缩短，手术成功率96.7%，3周存活率94.2%。

PTX at tenuates the ALI induced by LPS or sepsis in rat. The therapeutic effects of PTX include:improve oxygenation, at tenuate pulmonary edema formation, enhance animal survival in sepsis-induced ALI. The mechanisms may related with the effects of PTX inhibiting the chemotaxis, migration, activation of inflammatory leukocytes, diminishing the production of active oxygen, and inhibiting inflammatory cytokine release partly.

4PTX对大鼠内毒素性ALI及脓毒症性ALI均有一定的防治作用，主要表现在改善动脉血氧合，减轻肺水肿形成，提高脓毒症性ALI大鼠的存活率等方面，其机理可能与抑制白细胞趋化与激活，减少肺内白细胞渗出及活性氧产生，一定程度上抑制炎性细胞因子生成等有关。

The purpose of this study was to investigate the survivalof endoprosthetic reconstructions in the medium to long termin order to determine the factors associated with their failure.

本研究的目的在于调查中期至长期术后肿瘤型人工关节重建的存活率，从而确定影响手术失败的因素。

Results suggested that Terminalia catappa leaves have no effect on cell viability of SCC-4 cells. The modified Boyden chamber assays revealed that a treatment of Terminalia catappa leaves significantly inhibited the cell motility/invasion capacities of SCC-4 cells.

在本实验中，利用 50%酒精萃取的榄仁树的叶之萃取物处理 SCC-4 细胞株，并利用 MTT assays 分析方法显示榄仁树的叶萃取物并不会影响 SCC-4 细胞的存活率，而当癌细胞转移时常常会伴随著细胞外基质的分解及细胞移动能力的改变，接著我们利用 modified Boyden chamber assay 发现榄仁树的叶萃取物具有抑制 SCC-4 细胞的移动与侵袭能力。

The thalami were more sensitive to the treatment time than the concentration when EMS was used as a mutagen and 4 h was the proper treatment time under 0.4% EMS.

诱变苗在进行高温筛选时，存活率出现变化、叶色叶型发生变异，表明诱变与筛选是有效的。

The main results and conclusions are as follows: 1. Culrured neurons were damaged by simulated cerebral ischemia and reperfusion in vitro: Results:(1) The activity of the darnaged neurons was decreased, the survival rate was descent.(2) The transudation rate of LDH in cultured medium increased obviously.

体外模拟脑缺血再灌注造成了培养神经元的损伤：表现为：(1)受损神经元的活性降低，细胞存活率下降；(2)细胞培养液LDH的漏出率明显提高；(3)细胞死亡率显著上升；(4)NOS染色强阳性细胞数在缺血期和再灌注早期明显增多。

Methods and Results-: The triply n/i/eNOS-/- mice, but not singly eNOS-/- mice, exhibited markedly reduced survival, possibly due to spontaneous myocardial infarction accompanied by severe coronary arteriosclerotic lesions.

方法和结果--这种一氧化氮合酶亚型三重缺陷而非单一内皮型一氧化氮合酶缺陷的小鼠存活率显著降低，很可能是因为严重的冠状动脉硬化损害并伴发自发性心肌梗死。

The medical science research proves that the ovary cancer is unapparent in early symptom and when we discover the ovary cancer in final stage, it will make low survival rate.

医学研究证实卵巢癌在早期症状不明显，往往在最后阶段才发现，造成卵巢癌存活率很低。

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。
