In 3 groups of fetuses (n = 6 each) of cattle with a body mass of 4.18 +/- 2.1 (about 160 days old), of 9.72 +/- 0.97 (about 200 days old) and of 17.12 +/- 2.61 kg (about 230 days old) the content of DNA, RNA and protein in 19 different tissues was analysed. The wet weight:DNA-, the protein:DNA- and the RNA:DNA-ratios were calculated. The growth of the different tissues in the mentioned period of the development of the fetuses by hyperplasia and hypertrophy is discussed.
对3组体重分别为4.18±2.1千克(约160日龄)、9.72±0.97千克(约200日龄)和17.12±2.61千克(约230日龄)的牛胎儿(每组n = 6),分析了19种不同组织中的DNA、RNA和蛋白质含量。计算了湿重与DNA的比值、蛋白质与DNA的比值以及RNA与DNA的比值。讨论了在上述胎儿发育阶段不同组织通过增生和肥大的生长情况。
