外源性硫化氢对骨骼肌疲劳的影响

Abstract

Abstract: To investigate the effects of NaHS, an exogenous hydrogen sulfide donor, on skeletal muscular fatigue. Toad gastrocnemius was stimulated by pulse electric curent. The results showed that NaHS at concentrations of 5×10^-4 mol/L (in vitro, P < 0.01), 1×10^-3 mol/L (in vitro, P < 0.01), 2×10^-3 mol/L (in vitro, P < 0.01) and 5.6 mg/(kg·BW) (in vivo, P < 0.01) could prolong the time of contraction amplitude decreasing to 90%, 50% and 10% of the maximum contraction amplitude. The study showed that exogenous hydrogen sulfide had effect on antifatigue.
