RESUMO
<p><b>OBJECTIVE</b>To further analyze and identify effective components of anti-asthma in acupuncture serum.</p><p><b>METHODS</b>Changes of eosinophils in the peripheral blood of rats with eosinophilia were observed for 10 days after intravenous injection of the different segments of serum (serum: normal saline = 1:20, 2.5 mL/kg, from the first day of the model establishment, for 3 consecutive days).</p><p><b>RESULTS</b>After intravenous injection of different segments of serum, the eosinophil counts in the peripheral blood decreased significantly from the 3rd day as compared with those of the model group (P<0.05).</p><p><b>CONCLUSION</b>The effective components of acupuncture serum from asthmatic rats treated by acupuncture for eosinophils are not a single component, and acupuncture stimulation may produce many kinds of components of anti-asthma.</p>
