已往有些研究者证明了电离辐射能减少大鼠再生肝脏的 RNA 的合成和多核糖体RNA 的形成。但对这种改变的机理,特别是同肾上腺有何关系尚不清楚。为此,作者研究了肾上腺切除之大鼠(在杀死前两次腹腔注入醋酸皮质素,每次每只鼠2毫克,第一次在照射前12小时,第二次在肝切除前1小时)和未切除肾上腺大鼠再生肝脏 RNA的合成情况。 Some researchers have previously demonstrated that ionizing radiation can reduce the synthesis of RNA and the formation of polysome RNA in rat regenerative liver. However, the mechanism of this change, especially with the adrenal What is not clear. To this end, the authors studied adrenalectomized rats (corticosteroid acetate was injected ip two times prior to each injection, 2 mg per mouse per time, first for 12 hours before irradiation and second for 1 hour prior to hepatectomy ) And non-excised rat adrenal regeneration of liver RNA synthesis.
