It was found that Sibelium could significantly decrease the amounts of LDH leaking from intracellular fluid and increase the neuron-membrane fluidity of hypoxic neurons.Hypoxic group had significantly higher incorporation of 3H-TDR and 3H-UR than control group,while Sibelium could decrease the incorporation of 3H-TDR and 3H-UR. In addition,Sibelium could decrease the incorporation of 3H-TDR and 3H-UR in normal cultured neurons.The results showed that Sibelium could protect the neuronmembranes against alteration caused by hypoxia and regulate the synthesis of DNA and RNA.展开更多
