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 4

The integral optic density of the expression of PK2 and PKR2 in the colon of each group. Data are presented as M, min-max. Compared with the normal group: ^a𝑃<0.05, ^b𝑃<0.01; compared with the model group: ^c𝑃<0.01. N: normal group; M: model group; MM: mild moxibustion group.
