Improvement in inflammation and airway remodelling after acupuncture at BL13 and ST36 in a mouse model of chronic asthma:

Improvement in inflammation and airway remodelling after acupuncture at BL13 and ST36 in a mouse... Background: Asthma is a chronic inflammatory disease that affects millions of people worldwide. Chronic asthma is commonly resistant to steroid therapy. Acupuncture has an anti-inflammatory effect and has been widely used as an add-on therapy for asthma. Objective: To evaluate the effects of acupuncture on the inflammatory response and airway remodelling in the bronchioles of an asthma mouse model. Methods: A chronic asthma model was produced in female BALB/c mice by ovalbumin (OVA) sensitisation. 32 mice were randomised into four groups: control; asthma (OVA); OVA+BL13; and OVA+BL13+ST36. OVA was administered by intraperitoneal injection on days 0 and 14 followed by aerosol exposure of 1% OVA three times a week for 6 weeks. Manual acupuncture (MA) was performed three times a week for 6 weeks at BL13 alone, or BL13 in combination with ST36, in the two MA-treated groups. At the end of the experiment, blood samples were collected to determine eosinophil and neutrophil counts and lung tissue was prepared for histological examination. Results: A pronounced reduction in the neutrophil count was achieved after MA at BL13+ST36 (P=0.005) while the eosinophil count was lowered after MA both at BL13 (P=0.007) and BL13+ST36 (P=0.006). Reduction in the bronchiolar epithelial and smooth muscle thickness and the number of goblet cells was observed after MA at BL13 (P=0.001, P=0.001 and P=0.002, respectively) and BL13+ST36 (P=0.001, P=0.002 and P=0.001, respectively). Conclusion: Acupuncture can reduce the inflammatory response and prevent airway remodelling in a chronic asthma mouse model. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acupuncture in Medicine SAGE

Abstract

Background: Asthma is a chronic inflammatory disease that affects millions of people worldwide. Chronic asthma is commonly resistant to steroid therapy. Acupuncture has an anti-inflammatory effect and has been widely used as an add-on therapy for asthma. Objective: To evaluate the effects of acupuncture on the inflammatory response and airway remodelling in the bronchioles of an asthma mouse model. Methods: A chronic asthma model was produced in female BALB/c mice by ovalbumin (OVA) sensitisation. 32 mice were randomised into four groups: control; asthma (OVA); OVA+BL13; and OVA+BL13+ST36. OVA was administered by intraperitoneal injection on days 0 and 14 followed by aerosol exposure of 1% OVA three times a week for 6 weeks. Manual acupuncture (MA) was performed three times a week for 6 weeks at BL13 alone, or BL13 in combination with ST36, in the two MA-treated groups. At the end of the experiment, blood samples were collected to determine eosinophil and neutrophil counts and lung tissue was prepared for histological examination. Results: A pronounced reduction in the neutrophil count was achieved after MA at BL13+ST36 (P=0.005) while the eosinophil count was lowered after MA both at BL13 (P=0.007) and BL13+ST36 (P=0.006). Reduction in the bronchiolar epithelial and smooth muscle thickness and the number of goblet cells was observed after MA at BL13 (P=0.001, P=0.001 and P=0.002, respectively) and BL13+ST36 (P=0.001, P=0.002 and P=0.001, respectively). Conclusion: Acupuncture can reduce the inflammatory response and prevent airway remodelling in a chronic asthma mouse model.
