Root,immunoassay of ELISA(enzyme linked immunosorbent assay) was employed to determine IAA concentration in root tip, unilateral application of agar block containing IAA on root tip was carried out to investigate the effect of exogenous IAA on phototropic response.

为了研究生长素在水稻根负向光性反应中的作用，用含有IAA的琼脂块贴附在种子根的根尖表面观测IAA对根的生长效应，用ELISA法测定根尖的IAA含量，并对种子根弯曲部分进行半薄切片，结果表明：(1)种子根的生长方向既受光的调控也受外施的IAA的调控，根尖向贴有含IAA琼脂块的一侧弯曲生长；(2 )不定根在光照 1.5h后，背光侧的IAA含量明显大于向光侧；(3)种子根尖发生弯曲生长是伸长区的细胞不均等生长所致。

Compound A and B both inhibited the chemotaxis of polymorphonuclear leukocyte stimulated by fMLPP with 〓and 〓respectively.

目的：对剖宫产术后患者采用患者自控静脉镇痛与患者自控硬膜外镇痛的效果和不良反应进行比较分析。

By using β-NADPH-diaphorase histochemical staining technique,wefound for the first time that NOS activity was detected in the epithelium of airpathway and endothelium of vessels but was not detected in the small vessels(ID＜100μm),and the NOS express in pulmonary vascular endothelium of preascitic andascitic broilers were elevated,especially in the endothelium and smooth muscle layer ofsmall vesseles with thicker walls and of muscularized nomuscular artery in asciticbroilers.

本研究从田间自然发生腹水症的肉鸡群中选取正常肉鸡、亚临床腹水鸡和腹水鸡为实验对象，通过比较这三种肉鸡血流动力学、心电图、动静脉血血气、肺外动脉舒张反应性、肺血管结构以及肺组织一氧化氮合酶的活性和分布等方面的不同，探讨了肺动脉舒张能力在肉鸡肺动脉高压形成中的作用和机制。

These two mutants were prototrophic type and could cause hypersensitive reaction on tobacco leaves.However,their virulence decreased greatly in comparison with wild type.

经SDS-PAGE电泳，筛选出2个胞外蛋白减少9种的突变株PM2644和PM239，其可以引起烟草叶片典型的过敏性反应，致病力比野生型菌株显著降低，皆为原养型菌株。

Every indicatrion has statistics difference after six mouthstreatment of Two rattan mixture which include body function, activity index number of pathogenetic condition, total swelling arthrosis, total self-assessment, rachialgia, rachiodynia rhachitis, activity of thoracic skeleton, schober, distance between fingers and ground, left flection of antisternum, right flection of antisternum, antisternum hypsokinesis, distance between head and wall, ESR, C reactive protein: every indicatrion has statistics difference after the treatment of Sulfasalazine except the indicatrion of distance between head and wall.

二藤合剂组治疗6个月后其各项观察指标(包括躯体功能、病情活动指数、肿胀关节总数、总体自我评价、脊柱痛、脊柱炎症，胸廓活动度、Schober、指地距、脊椎左屈、脊椎右屈、脊椎后仰、枕墙距、血沉、C反应蛋白)与治疗前相比，均有统计学差异(P＜0.05)；柳氮磺吡啶组除枕墙距外，其余观察指标亦均有统计学差异(P＜0.05)。

Berberine is mainly used to treat major used in enteric bacterial infection,recently,researches showed that Berberine can not only be used to treat cardiovascular disease,endocrine disease,nutritional and metabolic disease,central nervous disease,tumors,but also can improve immune function and anti-graft rejective reaction of skin besides its antibacterial action.

黄连素在临床上主要用于治疗肠道细菌感染，但大量研究和临床应用表明，黄连素除了有抗菌作用外，还可用于治疗心血管疾病、内分泌、营养及代谢疾病、中枢神经系统疾病、肿瘤等疾病，同时具有增强免疫机能及抗皮肤移植排斥反应等作用。

Therefore, collagen metabolism is the center of the extracellular matrix remodeling in intracranial saccular aneurysms, while the essence of the remodeling process is a kind of autoimmunological and inflammatory reaction.

因此，胶原代谢是囊性动脉瘤细胞外基质重塑的核心内容，而重塑过程的实质是一种以细胞免疫为主的免疫炎性反应。

Low reaction of fetus to inflammation, different extracellular matrix, component of collagen fiber and cell factors may take part in scarless healing process. Regulation of gene expression may play an important role in the process. But the concrete mechanism of scarless healing is not clear yet and still needs more researches and elucidations.

胎儿对炎症的低反应性、胎儿不同的细胞外基质、胶原纤维的成分、细胞因子可能也参与了无瘢痕愈合过程、基因表达调控在其过程中可能也起重要作用，但无瘢痕愈合的具体机制还不明了，有待进一步研究阐明。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
