Aim. We aimed to investigate and evaluate the preventive activity of puerarin on the ovalbumin-induced asthma rat model. Materials and Methods. Male Wistar rats were sensitized intraperitoneally on days 0, 7, and 14 and challenged to ovalbumin intratracheally on day 21. Groups of sensitized rats were treated randomly either with placebo, puerarin, dexamethasone, or puerarin combined with dexamethasone, from days 15 to 20. Inflammatory markers, including cell counts in bronchoalveolar lavage fluid (BALF), inflammatory cytokines, histopathology, and coagulation parameters, such as coagulation tests and the activity of coagulation factors, were analyzed. Results. Puerarin significantly inhibited the recruitment of inflammatory cells in BALF and lung tissue. At the same time, the release of IL-4, IL-10, and IFN- gamma in serum and the expression of mRNAs in lung tissue homogenate were changed by puerarin. Administration of puerarin also effectively rectified the coagulation disorder in asthmatic rats, such as prothrombin time (PT) (P < 0.01), thrombin time (TT) (P < 0.05), fibrinogen (FIB) (P < 0.01),the activity of factor II (FII) (P < 0.01), the activity of factor V (FV) (P < 0.05), the activity of factor VII (FVII) (P < 0.05), the activity of factor X (FX) (P < 0.05), the activity of factor VIII (FVIII) (P < 0.01), the activity of factor IX (FIX) (P < 0.05), and the activity of factor XII (FXII) (P < 0.05). Conclusions. Our results provide a clue that puerarin was useful for the preventive of allergic airway disease in rodents.
