title: [Effects of electroacupuncture at "Zusanli" (ST 36) on hepatic ischemic injury in rats with delayed fluid replacement after hemorrhagic shock].
abstract: OBJECTIVE
  To investigate the effects of electroacupuncture at "Zusanli" (ST 36) on the volume of hepatic blood flow, water ratio and plasma alanine aminotransferase (ALT) in rats with delayed fluid replacement after hemorrhagic shock and to provide the references for electroacupuncture at Zusanli (ST 36) in treating hemorrhagic shock.
  
  
  METHODS
  Forty SD rats with hemorrhagic shock induced by bloodletting 40% of whole blood volume were randomly divided into a hemorrhage with no treatment (NT) group, an immediate fluid replacement (IFR) group, an electroacupuncture at Zusanli (ST 36) and delayed fluid resuscitation (EA/DFR) group and a sham electroacupuncture and delayed fluid replacement (SEA/DFR) group, 10 rats in each group. No treatment was performed in NT group. IFR group was treated with fluid replacement at 10 minutes after blood loss, and EA/DFR group was treated with electroacupuncture at "Zusanli" (ST 36) at 10 minutes after blood loss, while non-acupoint was punctured in SEA/DFR group. Two EA groups were received delayed fluid replacement at 3 hours after blood loss. The volume of hepatic blood flow and ALT before blood loss and 3 h and 12 h after blood loss, and water ratio 12 h after blood loss were measured.
  
  
  RESULTS
  After blood loss, all parameters in IFR group and EA/DFR group were improved significantly in contrast with those in NT group (all P < 0.05). There was no significant difference between SEA/DFR group and NT group. Three hours after blood loss, the hepatic blood flow of IFR group was significant higher than those of NT group, EA/DFR group and SEA/DFR group (all P < 0.05), while the plasma ALT of IFR group was significant lower than those of NT group, EA/DFR group and SEA/DFR group (all P < 0.05), and the plasma ALT of EA/DFR group was lower than those of NT group and SEA/DFR group (both P < 0.05), the hepatic blood flow of EA/DFR group showed no significant difference compared with that of SEA/DFR group (P > 0.05). Twelve hours after blood loss, the plasma ALT and the water ratio of EA/DFR group and IFR group were significant lower than those of NT group and SEA/DFR group (all P < 0.05), and the hepatic blood flow of EA/DFR group and IFR group was significant higher than those of NT group and SEA/DFR group (all P < 0.05), while the plasma ALT of IFR group was significant lower than that of EA/DFR group (P < 0.05), and the hepatic blood flow of IFR group was significant higher than that of EA/DFR group (P < 0.05).
  
  
  CONCLUSIONS
  Electroacupuncture at "Zusanli" (ST 36) has a protective effects for hepatic ischemic injury in rats with delayed fluid replacement after hemorrhagic shock.
