Mild Moxibustion Decreases the Expression of Prokineticin 2 and Prokineticin Receptor 2 in the Colon and Spinal Cord of Rats with Irritable Bowel Syndrome

Figure 5

PK2 expression in the spinal cord of chronic visceral hypersensitivity model rats (immunohistochemical detection). Yellow stains denote PK2-positive expression as shown by the arrows. PK2 was mainly expressed in the large, medium, and small neurons, vascular endothelial cells, and the interstitium of the spinal cord. (A3) normal group, (B3) model group, and (C3) mild moxibustion group. Scale bar: 20 μm.
