Visceral injury has been shown to induce somatic sensitization due to neuroinflammation, but little is known about the changes
in these somatically sensitized locations. Using gastric mucosal injury (GMI) model, we investigated the local histochemical
changes around these somatic sensitized areas (sensitized acupoints). Evans Blue (EB) dye is injected through the tail vein, and
the distribution of extravasated EB dots in the skin are observed and compared with the locations of acupoints. We detected the
expression of neuroinflammatory mediator (calcitonin gene-related peptide (CGRP) and substance P (SP))-labeled nerve fibers,
histamine (HA)-, serotonin (5-HT)-, and tryptase-labeled cells in EB dots. The EB dots induced by acute GMI were found in the
skin over the back and abdomen, innervated mostly by the T9-11 dermatomere. The dots disappeared gradually during natural self-
recovery of gastric mucosa from the injury. The consistent rates between EB dots and acupoints were BL20: 88.23%, BL21: 82.35%,
DU6: 58.82%, BL17: 47.5%, RN12: 17.64%, RN13: 5.88% respectively. Furthermore, nociceptive neuropeptides SP and CGRP were
expressed much higher in extravasated EB dots than that beside the EB dots or control, which were mostly distributed through the
nerve fibers around both the vessels and the root of hair follicle. Meanwhile, mast cells gathered, degranulated and released HA
and 5-HT around the vessels in areas within extravasated EB dots. We conclude that GMI results in somatic sensitization named
sensitized acupoints, where an elevated SP and CGRP expressed in nerve fibers, as well as of HA and 5-HT released in mast cells.
