Effects of marching with load of 1.5 kilograms in dry-heat desert on heat shock protein 70 in human lymphocyte

  Objective   To explore the regulation of heat shock protein 70(HSP70)in human lymphocyte in case of marching without load in dry-heat desert.

  Methods   The lymphocyte HSP70 of 54 marchers at different speed at different time and 14 controls were detected.

  Results   There was signficant difference between different speeds at the same time(P < 0.05);The lymphocyte HSP70 of group for 3 hours was obviously more than that of the control and the group for 2 hours at 3.5km/h; The level of HSP70 for 1 and 2 hours is more than the control at 5.0km/h(P < 0.05), but less than for 3 hours(P < 0.05).

  Conclusion   The lymphocyte HSP70 increased with speed and time.The blood lymphocyte HSP70 was more sensitive than plasma HSP70 in the monitor of heat injure and heat tolerance.
