Abstract:
Objective To study the biological activities of Synechococcus sp.PCC7942 with trans-mutated hCu,Zn-SOD-gene.Methods Synechococcus sp.PCC7942 with trans-mutated hCu,Zn-SOD were administered orally for 20d to mice,then the activities of glutathione peroxidase(GSH-Px),catalase(CAT),superoxide dismutase(SOD) and the content of malondialdehyde(MDA) were determined.Results The activities of GSHPx in serum and the activities of CAT in blood increased obviously;the activity of SOD in serum and liver increased markedly;the content of MDA in serum and liver decreased obviously.Conclusion Synechococcus sp.PCC7942 with trans-mutated hCu,Zn-SOD-gene had obvious antioxidant effect in vivo.
