到目前为止,对同煤尘接触工人膳食中脂肪成分尚无一致的意见和可靠的理论依据。根据实验和临床研究资料,维生素代谢有明显改变。我们实验的目的是研究不同脂肪营养时,实验性肺大鼠体内某些维生素的代谢。用雄性大鼠,共分六组,每组均摄入等热量半人工合成的含不同的脂肪成份的饲料。第一组为对照组,二、三组摄入1∶1的熟猪油和葵花籽油,四组摄入1∶1∶2的奶油,熟猪油和葵花籽油,五、六组摄入1∶1∶1.2∶0.8和1∶1∶0.5的奶油,熟猪油,葵花籽油和人造奶油。各组动物在6个月实验期,按每周5
So far, there is no consistent opinion and reliable theoretical basis for the dietary fat composition of workers exposed to coal dust. According to experimental and clinical research data, vitamin metabolism has changed significantly. The purpose of our experiment was to study the metabolism of certain vitamins in experimental lung rats in the presence of different fat nutrition. The male rats were divided into six groups and each group received an equal amount of heat and semi-artificial feed containing different fat components. The first group was the control group, the second group and the third group received 1:1 mature lard and sunflower oil, four groups took 1:1:2 cream, cooked lard and sunflower oil, and the fifth and sixth groups took Into 1:1:1.2:0.8 and 1:1:0.5 butter, cooked lard, sunflower oil and margarine. Each group of animals was tested at 5 months per week during the 6-month experimental period
