Relation between heat shock proteins and nitric oxide in marchers with load in desert

  Objective   To explore the relation between heat shock proteins(HSP70 and HSP27)and nitric oxide(NO) and nitric oxide synthase(NOS)in marchers in dry-heat desert.

  Methods   the plasma HPS70, HSP27, NO and NOS of 57 marchers at different speed of different time with 15 kg and of 14 controls were detected.

  Results   With 15 kg at both 3.5 and 5.0km/h, the plasma HSP27 in the marching groups were much more than the control(P < 0.05);the plasma HPS70 in the marching groups were slightly more than the control(P > 0.05);and the plasma NO in the marching groups were much lower than the control.NO for 1 hour was much more than the other marching groups at 3.5km/h.As for NOS, NOS for 1 hour was much more than the control and the other groups at 3.5km/h; and NOS for 2 hour was much lower than the control and the other groups at 5.0km/h.

  Conclusion   In the case of loading, there was a close relation between HSP27 and NO, NOS and no relation between HSP70 and NO and NOS in marchers in dry-heat desert.
