1正常和早熟雄性河蟹副性腺蛋白和血淋巴中17β-雌二醇及睾酮浓度的比较显示文摘采用常规生物技术方法,比较分析和测定正常(体质量20~30g)和早熟(95~130g)雄性河蟹Eriocheir sinensis的副性腺蛋白和血淋巴中17β-雌二醇和睾酮浓度的差异。结果表明,正常雄性河蟹和早熟雄性河蟹的副性腺中蛋白质的种类无明显差异,但是,早熟雄性河蟹副性腺中分子量在66.4~97.2k Da的蛋白表达量明显少于正常雄性河蟹。早熟雄性河蟹血淋巴中睾酮和17β-雌二醇的浓度显著低于正常雄性河蟹。分子量在66.4~97.2kDa间的河蟹副性腺蛋白质、睾酮及17β-雌二醇含量低可能是雄性河蟹性早熟的重要原因之一。潘颖 2018水产学杂志2018,31,3:1
2Chromatographic Fraction of Polygonum hydropiper Root Modulates the Expression of Transforming Growth Factor-βI (TGF-βI) in Rat Uterus during Days 2-6 of Gestation显示文摘Objective To examine the effect of the root extract on the growth factor during early pregnancy from day 2 to day 6 of gestation. Methods A purified form of root extract of Polygonum hydropiper was obtained by Thin Layer Chromatography (TLC). Localization of transforming growth factor (TGF)-βI was studied by immunohistochemistry and the expression of the mRNA of TGF-βI was studied by Reverse transcriptase Polymerase Chain Reaction (RT-PCR) in uterine tissue from day 2 to day 6 of gestation. Results The TLC fraction treated in a dose of 5 mg/kg body weight per day showed decreased the number of implantation sites. The expression of TGF-βI from day 2 to day 6 of gestation was altered by the TLC fraction and suppression of the mRNA transcript of the TGF-βI on day 6 of gestation during implantation. Conclusion The root extract of Polygonum hydropiper in a dose of 5 mg/kg body weight per day decreased the expression of TGF-βI in the implantation sites of rat uterus.Pranjiv Goswami Ajit Hazarika Hirendra N Sarma 2011Journal of Reproduction and Contraception2011,22,3:0
