Bottom Line: Severe burn injuries may result in gastrointestinal paralysis, and barrier dysfunction due to gut ischemia and lowered vagus excitability.The plasma diamine oxidase (DAO) and intestinal permeability decreased significantly after scald injury in the EA group compared with others.However, EA after atropine injection or cervical vagotomy failed to improve intestinal motility and mucosa blood flow suggesting that the mechanism of EA may be related to the activation of the cholinergic nerve pathway.

ABSTRACT
Severe burn injuries may result in gastrointestinal paralysis, and barrier dysfunction due to gut ischemia and lowered vagus excitability. In this study we investigate whether electroacupuncture (EA) at Zusanli (ST36) could prevent severe scalds-induced gut ischemia, paralysis, and barrier dysfunction and whether the protective role of EA at ST36 is related to the vagus nerve. 35% burn area rats were divided into six groups: (a) EAN: EA nonchannel acupoints followed by scald injury; (b) EA: EA at ST36 after scald injury; (c) VGX/EA: vagotomy (VGX) before EA at ST36 and scald injury; (d) VGX/EAN: VGX before EAN and scald injury; (e) atropine/EA: applying atropine before scald injury and then EA at ST36; (f) atropine/EAN: applying atropine before scald injury and then EA at nonchannel acupoints. EA at the Zusanli point significantly promoted the intestinal impelling ratio and increased the amount of mucosal blood flow after scald injury. The plasma diamine oxidase (DAO) and intestinal permeability decreased significantly after scald injury in the EA group compared with others. However, EA after atropine injection or cervical vagotomy failed to improve intestinal motility and mucosa blood flow suggesting that the mechanism of EA may be related to the activation of the cholinergic nerve pathway.

The level of plasma DAO was detected at −0.5, 2, and 6 h after scalds injury. Data are expressed as means ± SD (n = five animals at every time point per group). ∗ versus −0.5 h among the same group, P < 0.05; # versus EA group among 2 h and 6 h, P < 0.05.

fig4: The level of plasma DAO was detected at −0.5, 2, and 6 h after scalds injury. Data are expressed as means ± SD (n = five animals at every time point per group). ∗ versus −0.5 h among the same group, P < 0.05; # versus EA group among 2 h and 6 h, P < 0.05.

Mentions: Figure 4 illustrates the effect of EA at ST36 on the gut barrier function after 35% of TBSA scald injury by detecting the activity of diamine oxidase. Scald injury induced gut ischemia and had an impact on the gut barrier function. Animals in the EA group had a significantly lower level of plasma DAO when compared with the EAN group. EA at ST36 protected the gut barrier function after scalds injury, while vagotomy or intraperitoneal injection of atropine before EA at ST36 reversed its antiparalysis effects.
