【摘要】 用3H-甘氨酸参入法研究了家蚕五龄幼虫丝腺、脂肪体和中肠等器官白质合成活性的动态变化及蜕皮激素(简称MH)的影响。研究结果表明,五龄前期一次添食和每天连续添食MH能显著提高后部丝腺丝心蛋白和脂肪体蛋白质的合成活性,而抑制中肠蛋白质和五龄中后期中部丝腺丝胶蛋白的合成活性。此结果,为阐明MH对蚕体蛋白质合成的调控作用提供了直接的证据。更多还原

【Abstract】 The 3H-glycine laballed method is used for studying the effect of B-ecdysone ( MH ) on the change of the protein synthesis activity in the silk gland, fat body and midgut during the fifth instar larvae of Bom-byx mori. The results obtained in the present experiment showed that oral administration of MH for once at the early stage and daily continuously in th fifth instar larvae can enhance apparently the activity of the fibroin synthesis in the postrior portion of the silk gland and the protein synthesis in the fat body, but inhibit the activity of the skein synthesis in the middle divison of the silkgland and the protein synthesis in the midgut, which provide direct evidence for elucidating that the MH can regulate the protein synthesis of Bombyx mori.更多还原
