Effects of electroacupuncture at lower he-sea points on interleukin-1β and high mobility group box 1 in model rats with ulcerative colitis

ObjectiveTo comparatively observe the effect of electroacupuncture at digestive system-related lower he-sea points on the expressions of serum interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) of colon tissues and high mobility group box 1 protein (HMGB 1) of ulcerative colitis (UC) model rats, and to explore whether there is relative specificity of electroacupuncture at Shàngjùxū (

ST 37), one of lower he-sea points of large intestine, in treatment of bowel diseases.MethodA total of 60 SD rats were randomly divided into control group, model group, ST 37 group, Zúsānlľ (

ST 36) group, Xiàjùxū (

ST 39) group and Yánglíngquán (

GB 34) group. There were ten rats in each group; five were males, and five were females. UC models were established by clysis with 2, 4, 6-trinitrobenzene sulfonic acid/alcohol solution. After modeling, treatment was conducted for ten days, specimens were collected, colonic ulcers and inflammation were inspected visually and scored. The content of serum IL-1β and the expressions of TNF-α and HMGB 1 in colon were detected through ELISA.Results

Compared with control group, the scores of colonic ulcers and inflammation, the content of serum IL-1β and the expressions of TNF-α (except ST 37 group) and HMGB 1 were all higher (P<0.05, P<0.01);

compared with model group, the scores of colonic ulcers in ST 36 group and ST 37 group were lower obviously (P<0.05, P<0.01); the expressions of IL-1β, TNF-α and HMGB 1 in the four treatment groups were lower obviously (P<0.01);

compared with ST 37 group, the expressions of IL-1β, TNF-α and HMGB 1 in other three treatment groups were higher obviously (P<0.05, P<0.01); and the scores of colonic ulcers in ST 39 group and GB 34 group were higher obviously (P<0.05).Conclusion

The score of colonic ulcers can be reduced through electroacupuncture at ST 37, ST 36, ST 39 and GB 34, which can also reduce the content of serum IL-1β and the expressions of TNF-α and HMGB 1, and effectively inhibit inflammatory response of colon caused by UC;

the effect trend of the four acupoints in treatment of UC is: ST 37>ST 36>ST 39>GB 34, and electroacupuncture at ST 37 has the best effect with relative specificity.

Effects of adrenocorticotropic hormone and electroacupuncture on formalin-induced NOS-positiTe neurons in the spinal cord of rats

AIM:To study the effects of adrenocorticotropic hormone (ACTH)and elec-troacupunctune (EA) on formalin-induced nitric oxide synthetase (NOS) -positive neurons increases in the spinal cord of rats. METHODS: ACTH was administered by intrathecal injection (i. t )and EA stimulation on "jiaji" point was performed by 1 mA 50 Hz, 5 mA 5 Hz and 1 mA S Hz respectively. The NOS-positive neurons were assayed by NADPH-diaphorase histo-chemistry. RESULTS: The results showed that both ACTH (0. 5 u, i. t. )and EA stimulation (1 mA 50 Hz, 5mA 5 Hz, ImA 5Hz) on "jiaji"point 30 nan significantly reduced the formalin-induced NOS-positive neurons in the rat dorsal horn. The combinative use of ACTH (0. 5 u, i. t, ) and EA(1 mA 5 Hz) caused a more marked reduction of the numbers of NOS positive neurons than that of the single ACTH or EA. Those effects were partially reversed by pretreatment with either the substrate of NOS, L-arginine (10 nmol, i. t. ) or opioid antagonist naloxone(10 g, i. t ). CONCLUSION: These results sug
