1967年以来,Ahlers等曾报道大鼠在连续照射后,甚至在照射期间就发生了血清类脂(即三脂酰甘油、总胆固醇和磷脂等)和肝、胸腺、骨髓中的三脂酰甘油浓度的增高,但连续照射所致的血清和组织类脂代谢病的病因仍未能阐明。本文报告用大鼠以每日剂量为0.57Gy的γ射线连续照射25天或30天,期间分别测定体外1-~(14)C醋酸盐掺入肝切片中的总类脂,脂肪酸和胆固醇的掺入量以及U-~(14)C葡萄糖掺入白脂肪
Since 1967, Ahlers et al. have reported that after continuous irradiation in rats, serum lipids (ie, triacylglycerols, total cholesterol, phospholipids, etc.) and triacylglycerols in the liver, thymus, and bone marrow occur even during irradiation. The increase in concentration, but the etiology of serum and tissue lipid metabolism caused by continuous irradiation has not been elucidated. This report reports the continuous determination of total lipids, fatty acids, and cholesterol in liver slices with 1-(14)C acetate incorporation in vitro using γ-rays at a daily dose of 0.57 Gy for 25 days or 30 days. Incorporation and U-~(14)C Glucose Incorporation into White Fat
