摘　　要：运用体外放射化学方法研究孕酮对克氏原螯虾(Procambarus clarkii)大颚器官(MO)生物合成甲基法尼酯(MF)的调控作用。结果表明,低浓度孕酮(10 pmol/L,100 pmol/L)对MO生物合成MF的抑制作用不明显;高浓度孕酮(1 nmol/L,5 nmol/L,10 nmol/L)对MF生物合成具有极显著的抑制作用(P<0.01)。表明较高的血淋巴孕酮水平对克氏原螯虾MO合成MF产生反馈抑制作用。研究中对涉及MF合成的眼柄-大颚器官-卵巢轴的调节机理作了探讨。In vitro regulation of hormone biosynthesis of MO by progesterone in Procambarus clarkii was investigated by using radiochemical method. It was found that lower concentration of progesterone （10 pmol/L, 100 pmol/L） had no conspicuously effect on MO, but higher concentration of progesterone （1 nmol/L, 5 nmol/L, 10 nmol/L） showed significant inhibitory effect on MO （P〈0.01）, which sug- gested higher level of progesterone in haemolymph had a negative feedback or inhibitory effect on MF biosynthesis of MO. A regulation mechanism of eyestalk-mandibular organ-ovary axis on MF biosynthesis was also discussed in this paper.
