Electroacupuncture at ST25 inhibits jejunal motility: Role of sympathetic pathways and TRPV1

Figure 5 Jejunal response of type C rats to electroacupuncture stimulation at ST25, and effect of propranolol and clenbuterol on electroacupuncture- induced inhibition of jejunal contraction in type C rats. Representative examples of electroacupuncture (EA) stimulation at ST25 with different intensities in type C rats (A); The fitting curve of the inhibitory effect of EA stimulation at ST25 on jejunal motility in type C rats (B); Representative examples of EA stimulation at ST25 with different intensities after administration of propranolol administration (C); The fitting curve of inhibitory effect of EA stimulation at ST25 on jejunal motility in the presence of propranolol (D); Representative examples of EA stimulation at ST25 with different intensities after administration of clenbuterol (E); The fitting curve of inhibitory effect of EA stimulation at ST25 on jejunal motility in the presence of clenbuterol (F). ∆: Time of drug administration (n = 8).
