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 9

The relative expression levels of PK2 and PKR2 mRNA in the colon in each group (%). Data are presented as mean ± SD. Compared with the normal group: ^a𝑃<0.05, ^b𝑃<0.01; compared with the model group: ^c𝑃<0.05, ^d𝑃<0.01. N: normal group; M: model group; MM: mild moxibustion group.
