Results Compared with CRF group, nephrogenic hypertension of hemin group was reduced significantly at the 6th, 8th, 10th week after operation, and followed with the decrease of serum creatinine, BUN,urinary protein and the improvement of nephrogenic anemia at the 10th week after operation. Hemin not only increased the expression of HO-1, reduced the expression of ET-1 in the kidney, but also increased the concentration of carbon monoxide, reduced the level of ET-1 in the plasm.

同时，在术后第10周hemin组比CRF组血肌酐、尿素氮、尿蛋白显著降低(P＜0.05)，贫血明显改善(P＜0.05)；肾组织中HO-1表达明显增加，血浆中内源性CO水平明显升高，肾组织和血浆中ET-1水平明显降低(P＜0.05)。

Women with polycystic ovarium syndrome who had failed to conceive on treat- ment with conventional IVF-ET protocol or during six ovulatory cycle on gonadotropin un- derwent 26 cycles of IVF-ET by conbined long-acting gonadotropin-releasing hormone ago- nist and gonadotropin.

在体外受精－胚胎移植周期中，应用长效促性腺激素释放激素激动剂（go－nadotrophinreleasinghormoneagonist，GnRH－a）合用促性腺激素（gonadotrophin，Gn）治疗26例顽固性多囊卵巢综合征患者并与其中19例前次常规IVF－ET方案治疗的结果相比较。

From parasternal long axis, LVDd and LVDs were measure by M-mode;From apex four chanmber view, EDV and ESV were measure by simplified Simpson method, LVEF was calculated, and by the pulse doppler of mitral and aortic valves, mitral valve diasolic flow E wave, A wave, ICT, IRT,and ET were measured.

AMI患者74例入院后行超声心动图检查，在胸骨旁长轴用M型测量LVDs，LVDd，心尖长轴切面用简化Simpson氏法测量EDV，ESV，并计算LVEF，多谱勒超声心动图采集测量二尖瓣和主动脉瓣血流频谱，测量二尖瓣舒张期血流E峰，A峰，ICT，IRT和ET，按公式计算Tei指教=/ET。

The resultsshowed that one electron was photochemically transfered from rich electron part inside the C〓 derivatives to C〓 football. On the other hand,two step PET took place between C〓 and additional electron donor Et〓N, and so C〓anion as well as C〓 dianion could be detected in C〓/ Et〓N system.

结果表明：C〓衍生物分子内的富电子部分与C〓区域间发生分子内光诱导的一步单电子转移过程，对比而言，C〓分子与外加给体Et〓N间可相继发生两步光诱导电子转移反应，依次生成C〓和C〓阴离子自由基。

Objective To investigate the effects of benazepril on urinary excretion of endothelin-1(Et-1) and the level of plasmic Et-1 in patients with diabetes mellitus and diabetic nephropathy.

目的 探讨苯那普利对糖尿病肾病患者肾脏产生及尿液排泌内皮素-1(Et-1)的影响。

The dynamic changes of endothelin-1 in cerebrospinal fluid , brain tissues and plasma and ET〓-RNA expression in hypothalamus, hippocampus and temporoparietal grey and white matters were observed by radioimmunoassay methods and spot hybridization respectively.

四、建立双后肢高速、低速投射物致伤犬应激模型，应用核酸斑点杂交和放射免疫分析法，检测分析致伤前及致伤后10min、1h、2h、6h、8h，对犬的脑组织、血浆、脑脊液中的ET〓（内皮素-1）含量及海马、丘脑下部、颞顶叶灰、白质中ET〓-RNA表达的动态。

Results The contents of ET, ALT and total bilirubin were significantly lower on 7-day and 14-day after operations as compared with that during operations (P0.05 and P0.01). The concentration of ET in peripheral veinous blood paralleled with that in bile.

结果 术后7天、14天上述指标明显降低(P＜0.05和P＜0.01)，外周血和胆汁中ET浓度变化呈平行关系。

Though the primary stimulator of 1H is not clear, it is related to physical, cell and body fluid IH is a chronic process involving multiple faction injury and blood flowing abnormal are revamped as the main reason, the proliferation level depend on the length and width of the injure of vessel large amount research illustrate injury cause many growth factor infolded in IH, for example: template derived growth factor, fibroblast growth factor, transmission growth factor , endothelin (ET-1) et al, some early responsive gene such as c-fos、c-jun c-myc also take part in SMC proliferation after vessel injury.

虽然IH的确切起始刺激因子并未阐明，但已知与物理、细胞和体液因子有关。IH是一个多因素参与的慢性过程，损伤和血液动力学异常一真被认为是IH的主要因素。内膜增殖的程度有赖于血管损伤的长度和深度。近年来大量的实验研究结果表明，损伤等刺激引起的众多的生长因子样物质在IH中起关键作用。如血小板源性生长因子、碱性纤维母细胞生长因子、转化生长因子β、内皮素-1（ET-1）等诸如C-fos、C-jun、C-myc等早期应答基因也参与了血管损伤后SMC的增殖。

Plasma ET was higher in high altitude residents than in lowlanders, while NO lower in high altitude residents than in lowlanders.

高原居民血浆ET含量较平原居民高而NO含量较平原居民低，世居高原藏族人和移居高原汉族人相比，其血浆ET和NO含量更接近平原水平。

The main results obtained are as follows:(1)A new multisignature scheme for specified group of verifiers is proposed;(2) A new signature scheme with threshold shred verification is proposed. Based on the proposed scheme, a new password shared authentication scheme is presented to repair the security flaw in Qi et als scheme;(3) We point out some weaknesses of two directed signature scheme proposed by Lim et al.

作者取得的主要研究成果如下：(1)提出一个新的针对指定接收组的多重签名方案；(2)提出一个新的门限共享验证签名方案，并设计了一个新的口令共享认证方案，该方案可以弥补祁明等的方案的不足；(3)指出Lim et al。
