This study firstly discover and denounced that hCG is not only an important endocrine hormone in pregnancy, but also an important autocrine hormone for trophocyte and JAR cell. It directly influence cellular proliferation and endocrine function of JAR or trophoblastic cells.

六、本研究首次揭示并提出了hCG不仅是重要的妊娠期内分泌激素，而且对于JAR细胞而言，可能也适合正常妊娠滋养细胞，hCG是重要的自分泌激素，直接影响JAR细胞或滋养细胞的生长增殖与内分泌功能，可能也是必须的在局部产生作用的自分泌激素之一。

Glucocorticoids are effective in inducing apoptosis via the uncharacterized mechanisms in many hematological malignancies. GC-induced apoptosis is initiated by, and strictly dependent upon, the interaction of GC with its receptor, the GR.

糖皮质激素(glucocorticoid，GC)通过与其特异性受体-糖皮质激素受体(glucocorticoid receptor，GR)结合，不仅可诱导未成熟胸腺细胞凋亡，而且对急性白血病细胞、淋巴瘤细胞、骨髓瘤细胞等均有促凋亡作用，诱发凋亡正是应用糖皮质激素治疗白血病的分子生物学基础。

The author consider that the grana are steroid hormone according to the studies of domestic and overseas scholars, the big grana should be androgens, the small grana should be estrogens.

作者结合国内外学者的研究分析，这种颗粒物质是类固醇激素，大颗粒应该是雄性激素，小颗粒应该是雌性激素。

Compared with their thinner counterparts, obese men had lower levels of testosterone in their blood, as well as lower levels of luteinizing hormone and follicle-stimulating hormone -- both essential to reproduction.

和瘦的受试者相比，肥胖男性血液中的睾酮水平较低，同时促黄体激素和促卵泡激素的水平也较低，这两种激素对生育至关重要。

In the toped and untoped tobacco when applied with hormone, both content of IAA and GA3 increased but others decreased in tobacco that treated with IAA and GA3; The content of ABA increased significantly but the content of IAA and GA3 decreased when applied with ABA.

打顶与不打顶喷施外源植物激素的处理中，IAA和GA_3均可使叶和根中该激素含量提高，而其他激素含量下降；喷施ABA可以使烟株体内ABA明显增加，IAA和GA_3含量下降，ZR略有增加，但增幅不大。

A hormone secreted by the posterior lobe of the pituitary gland that constricts blood vessels, raises blood pressure, and reduces excretion of urine.

腺性垂体前叶脑下垂体腺的腺性前叶，可分泌包括促肾上腺皮质激素、乳汁刺激素以及促长激素的多种激素

Testosterone, the primary male sex hormone, is one in a group of related steroid hormones referred to as androgens.

睾酮是主要的雄性激素，也是一组被认为是雄性激素的类固醇激素的成员之一。

Testosterone, the primary male sex hormone, is one in a group of related steroid hormone s referred to as androgens.

The dosages of exogenous hormone were determined by the ovary maturation coefficient of brooders when inducing spawning artificially.

因此，在进行人工催产时，应根据催产亲鱼的性腺成熟系数决定外源激素的剂量，性腺成熟系数较大者，其外源激素的剂量宜小些；而性腺成就系数较小者，其外源激素的剂量宜大些。

As endogenous jasmonates exist in enantiomers in nature and at level of nanogram/per gram fresh weight, it is very challenging work to develop rapid and accurate method for qualitative and quantitative analyses of JAs. This review paper summarizes the recent advances in the analysis of jasmonates including chromatography, capillary electrophoresis, chromatography-mass spectrometry and immunoassay.

内源茉莉酸类激素通常以多种手性异构体存在，且含量超微，因此，对内源性茉莉酸类激素进行准确的定性、定量分析具有很大的难度，研究高效分离富集、高灵敏度检测以及分离与检测联用等分析方法，对加速植物激素分子作用机理研究具有重大意义。
