[Expression of CCR3 and CD34 in lung tissues and bone marrow of Guinea pig asthmatic models].

Aim: To explore the mechanism of asthma, by evaluating the changes of CCR3 and EOS expression in the lung tissues and bone marrow of Guinea pig asthmatic models at different times.

Methods: Guinea pigs (GPs) were sensitized and challenged by OVA to establish the asthmatic model (A, B, C, D, E) . The GPs in control (N) were sensitized and exposed to sterile saline.
