Methods Affinity chromatography purified plasminogen was digested by pancreatic elastase and angiostatin was obtained by purifying the digestion with affinity chromatography and dialysis. T739 mice were inoculated with LA795 cells. Angiostatin was given to part of inoculated and uninoculated mice by intraperitoneal injection fourteen days after the inoculation. The treatment lasted 20 days and the size of tumor, survival period, behavior of the mice and pathology of lungs, livers and kidneys were observed.

用亲和层析方法得到的血浆纤维溶酶原经胰蛋白酶消化、层析柱亲和层析、透析，得到纯化的血管抑素；以LA795细胞接种于T739小鼠；接种后第15日起腹腔内注射血管抑素共20 d，观察动物行为，测量荷瘤鼠肿块直径，记录生存期，另设未治疗对照组及观察血管抑素副作用对照组，行肺、肝、肾脏病理学检查。

It has been warranted through experiments and practical application that rare-earths-high-aluminium heat-resistant nodular iron has some intrinsic properties which are worthy of reconimandation, namely,that it will not scale after long periods of use at 1050-1100℃, will hardly break while being hammered into castings, runners or risers as the high-temperature tensile strength reaches 14-19 kg/mm2 at 800℃ or≥l3.3kg/mm2 at 900℃, with the room temperature strength close to HT 30-50 and the unnotched impact str...

本文介绍了稀土高铝耐热球墨铸铁的生产实践、化学成分；探讨了稀土作用及其用量和控制；论述了稀土和铝加入方式以及冷却速度对金相组织的影响；并对铸造工艺、铸件缺陷及分析、耐热性能及使用效果作了阐明。试验和使用证明：稀土高铝耐热球墨铸铁在1050～1100℃长时间工作不起氧化皮，热强度800℃时，14～19kg/mm~2，900℃时≥13.3kg/mm~2，室温强度近于HT30—54，a_k≈2～6kg·M/cm~2，锤击铸件或浇冒口，很难碎裂，并能机械加工。可以认为是以我国富产资源为原料，能用各种炉子熔炼、耐热和综合机械性能均较高硅、中硅中铝球铁、高铝片墨铸铁为高的一种耐热铸铁，也是镍铬系耐热材料较好的替代品。

According to documentary sources, large medallion carpets (of which the Turkish Star Ushak is a variant type) were woven in the western Anatolian town of Ushak , known for carpet weaving since the fifteenth century.

The results showed that a neural structural relation between the NRF and the ventrolateral medullary surface does exist.

结果表明NRF与腹外侧表面存在神经结构联系，微量注射酸化人工CSF和DLH于NRF能引起呼吸活动加强，微电泳H〓主要引起NRF吸气相关单位兴奋，呼气相关单位抑制，提示NRF在中枢化学感受功能中也起着一定的作用。

To promote a test zoologic of course of this one foundation deepen and the system develops, highlight course characteristic, hold experimental animal to study horizontal forward position, decide definitely below the times setting that accords with existing course development, ask to fall in the consistent proposal of wide readership and author, in April 2006 classics country news publishs total arrange to approve, rise from January 2007 " experimental animal science and management " will formal more the name is " experimental animal science ".

为推动实验动物学这一基础学科的深化和系统发展，突出学科特征，把握实验动物探究水平前沿，在符合现有学科发展的时代背景下准确定位，在广大读者和作者的一致建议要求下，于2006年4月经国家新闻出版总署批准，自2007年1月起《实验动物科学和管理》将正式更名为《实验动物科学》。

However, since fibres from these areas are projected forward into the cerebral cortex where the primary transmitter is acet ylcholine, attention has focussed on the management of this mediator in the searc h for appropriate therapeutic agents.

一些尝试关注和集中于其他的一些媒介的功能，比如作为中脑部媒介的5-hydroxytryptami ne，但是因为这些区域中的神经纤维投射向乙酰胆碱在其中起主要作用的神经皮层，关注焦点就转向寻找具有适当疗效物质来治疗和控制该类媒介。
