OBJECTIVE: To explore the protective effects and mechanisms of electroacupuncture (EA) at Zusanli (ST36) acupoint in rats with severe acute pancreatitis (SAP).
METHODS: Sixty-six male Sprague-Dawley rats were randomly assigned to three groups of 22 each: a SAP model group (SAP group), a shamoperated group (sham group) and a EA at ST36 acupoint group (EA group). A rat model of SAP was induced by pancreatic duct injection with 3.5% sodium taurocholate. EA was performed at ST36 acupoint for 30 min after induction of SAP and 30 min before sacrificed. The rats were killed at 3 h (n=7), 6 h (n=7) and 12 h (n=8) after operation, and blood samples were taken for the measurement of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and acetylcholine (Ach) by enzyme-linked immunosorbnent assay. The pathological changes of pancreatic tissue, volume of ascites and pancreatic weight/body weight ratio were measured.
RESULTS: The serum concentrations of TNF-α and IL-6 in the EA group were significantly lower than in the SAP group at 3, 6 and 12 h after the operation (p<0.05). Serum Ach in the EA group was significantly higher than in the SAP group at various time points after operation (p<0.05). The other parameters were clearly improved after treatment with EA.
CONCLUSION: EA at ST36 acupoint might have a therapeutic effect in rats with SAP through activating the cholinergic anti-inflammatory pathway.
