Objective To observe the effect of acupuncture on c-fos expression in the lung tissue of asthmatic rats. Methods Totally 70 SPF grade male SD rats were randomly divided into 7 groups, i.e., the blank group (A) , the asthma model group (B) , the blank control group (C) , the asthma-model acupuncture control group (D) , the asthma model acupuncture group ( E) , the asthma model sham-acu- puncture group (F) , the blank acupuncture group (G) , 10 rats in each group. Corresponding interventions were performed to each group. The protein expression of c-fos in lung tissue of rats was detected u- sing immunohistochemistry and Western blot respectively. Results Immunohistochemistry showed negative expression of c-fos protein in Group A, C, G, and E, and weakly positive in Group B, D, and F. Results of Western blot showed the protein expression of c-fos was higher in Group B than in Group A and E (P0. 01). The protein expression of c-fos was lower in Group E than in Group D and F (P0. 05, P0. 01). Conclusion Acupuncture could reduce the protein expression of c-fos in lung tissue, thus attenu- ating inflammation reaction. |
