Dihydrofolate reductase activity did not change with variations of mitotic rate in foetal rabbit haemopoietic tissue, whereas the activity of thymidylate synthetase declined with decrease in cell divisions. Both the activities were normal in the brachydactylia strain, in which a failure in folate metabolism was previously assumed.
在胎兔造血组织中,二氢叶酸还原酶的活性不会随着有丝分裂率的变化而改变,而胸苷酸合成酶的活性则随着细胞分裂的减少而下降。在短指畸形品系中,这两种酶的活性均正常,此前曾认为该品系存在叶酸代谢缺陷。
