Objective: To study the anti-fatigue effect and mechanism of atrial natriuretic peptide(ANP)on mice. Method: We observed the effect of ANP(13.10
6.55 ng·kg-1
iv) on the weight-loaded swimming time of the mice and the changes of gastrocnemius malonaldehyde (MDA). In vitro experiment
we observed the effect of high dose ANP(13.10 ng·kg-1) on H2O2(0.2 mol·L-1)induced mice gastrocnemius MDA. Result: ANP (13.10 ng·kg-1) could significant increase weight-loaded swimming time(P<0.01) and reduced the contents of MDA(P<0.05)compared with control group; ANP (13.10 μg·L-1) had the protective effect on H2O2 induced tissue injury of gastrocnemius (P<0.001)
but the blocker LY83583 of protein kinase G prevented the protective effect. Conclusion: ANP has the anti-fatigue effect
its role relevant to the signal transduction pathway of ANP-cGMP-protein kinase G(ANP-cGMP-PKG).
