objective to investigate whether hypoxia preconditioning exist in adipose tissue,and construct the hypoxemic model of adipose tissue.methods after injected different density cocl2 to rat's subcutaneously of groin,use immunohistochemical method detect hif-1α protein,and use rt-pcr detect hif-1α mrna.results after injected different density cocl2,the adipose tissue of rat's groin express different degree of hif-1αprotein and hif-1αmrna.,and reach the peak when the density is 20-40 mg/kg and the time is 3 h.conclusion hypoxia preconditioning exist in adipose tissue,and the effect of preconditioning is most evidence when the density is 20-40 mg/kg and the time is 3 h.

目的 探讨脂肪组织中是否存在缺氧预适应现象，构建cocl2致缺氧的缺氧模型。方法不同浓度的cocl2大鼠腹股沟区皮下层浸润注射，分别用免疫组织化学法和rt-pcr法检测该区脂肪hif-1α蛋白和hif-1α mrna的表达情况。结果用不同浓度的cocl2行化学缺氧后在不同时间点观察有不同程度的hif-1α蛋白和hif-1α mrna表达，其中，在浓度为20～40 mg/kg，时间为3 h时脂肪组织中hif-1α表达达高峰。结论脂肪组织存在缺氧预适应现象；cocl2的浓度选择20～40 mg/kg，时间选择3 h时缺氧预适应效果较佳。

The lead concentrations of trees and soils in urban Guangzhou are measured in this study.The results show that:mean lead concentrations of tree and top soil are respectively 23.4 mg/kg and 63.9mg/kg.

本研究测定了广州城市树木和土壤的铅含量，结果表明：广州城市树木叶子和表土的平均含量分别为23.4mg/kg和63.9mg/kg。

In order to accomplish this change, our research have made several important break-through by revising new formulation especially in (1) catalyst mix,(2) adjustment of water content,(3) addition of chain extenders and crosslinkers, and(4) utilization of long-chained polyols. By doing so, the general performances of our new non-yellowing foam products are comparable to those of the traditional TDI based products. In certain mechanical properties in areas such as tensile strength, split tear strength, and elongation our measured values of 1.89 kg/cm2, 1.47 kg/cm, and 355 % respectively have out-performed the old materials.

能在研究中突破的原因，是因针对聚胺酯发泡体配方中的催化剂、水含量、链长剂种类、交联剂及搭配商业之改质长链三元醇，做各式各样之配方调整而成，与传统商业用之芳香族发泡体相比较，基本的成泡指数及性质相比拟上已相近，在抗张(1.89 kg/cm2，比TDI系统增加2.2倍)、撕裂(1.47 kg/cm，比TDI系统增加1.7倍)、延伸率(355 %，比TDI系统增加1.6倍)等机械性质上甚至比芳香族发泡体有更佳的表现。

The results presented in this paper indicated that sodium salt of 3,7-bishemis uccinate of 7-hydroxycholesterol (RS 634) at the dose of 45mg/kg/day (×7,ip) could increase DNA, RNA and protein syntheses in bone marrow cells and protein synthesis in liver,spleen and serum, but no markedly effects on DNA and RNA synthesis in liver and spleen of mice bearing EAC were observed, In the subacute test on rats RS 034 (400mg/kg/day, x30 ip) showed no evident effects on the number of RBC, WBC and the percentage of lym...

本文报告的结果表明7β-羟基胆固醇双琥珀酸单酯钠(RS 024)在有效抗肿瘤剂量下(45mg/kg/day，×7ip)对荷瘤小鼠骨髓细胞DNA、RNA和蛋白质合成有促进作用，对肝、脾的DNA、RNA合成无显著影响，但能促进肝，脾中及血清蛋白质合成。按400mg/kg/day连续给药30天，对大鼠红细胞、白细胞数及淋巴细胞百分率无明显影响。提示该药在有效抗癌剂量下毒性较小，并在一定程度上对免疫功能有增强作用。

The objective of this paper was to investigate the effect of different treatments on fermentation quality of Xinjiang small reed and its nutrition constituent at different growth periods (heading period, blooming, fruiting). The five kinds of ensiling treatments (Fresh grass ensilage, fresh grass +10.0 g or 15.0 g molasses/kg, fresh grass +2.0 mL or 3.0 mL formic acid/kg) were carried out in the same growth period and its fermentation qualtiy and nutriton constituent were compared with each other.
