Objective: To correlate the effects of the Electroacupuncture (EA) with the levels of TNF-α and the gastric contractility in both ulcerated and non-ulcerated control rats.
Methods: Before the experiments, a magnetic marker was surgically implanted in the gastric serosa of all animals used in this study. Ten days after the surgical procedure, the animals were randomly assigned in groups (n=9 per group) whose received by gavage phosphate buffered saline (non-ulcerated control groups) or ethanol (ulcerated groups). EA treatments were applied every three days during 16 consecutive days in both control (C) and ulcerated (U) groups at sham (S) point (CS and US) and ST-36 acupuncture point (CST-36 and UST-36). Magnetic and electrical gastric activity recordings were also performed. TNF-α was measured by ELISA and all data were statistically analysed by ANOVA.
Results: In the ulcerated animals which received sham EA (US), the frequency and amplitude of contractions were reduced, whereas the levels of TNF-α were increased. EA applied at UST-36 group had significantly increases in the frequency and in the amplitude of contractions. A clear inverse correlation (ρ=0.9) between motility parameters and TNF-α levels in ulcerated rats was observed.
Conclusion: EA in ST-36 had improves the gastric contractility in ulcerated rats by a pathway that involves decreases in the levels of TNF-α.
