ABSTRACT
Objective To study the effect of ultrashortwave irradiation and chest-wall vibration therapy on serum eosinophil cationic protein(ECP)and percentage of eosinophil(EOS%)in the sputum of children with mild to moderate asthma. Methods A total of 68 children with asthma were divided into a control group and a treatment group.The control group WaS treated with conventional treatment only,while the treatment group was given ultrashortwave irradiation and chest-wall vibration therapy in addition to the conventional treatment.The serum ECP,EOS% in induced sputum,FEV1.0%,and PEF% were measured before and after treatment.The relationships among ECP,EOS%,FEV1.0% and PEF% were analyzed.Results FEV1.0% and PEF% were negatively correlated with serum ECP and EOS% in children with asthma.Compared with the control group,ECP and EOS% were significantly reduced after treatment,while FEV1.0% and PEF% were significantly elevated. Conclusion Uhrashortwave irradiation and chest-wall vibration therapy can improve ventilation by ameliorating airway inflammation and obstruction.
