OBJECTIVETo establish an evaluation system for animal model with gynecological disease characterized by Qi stagnation and blood stasis syndrome, in order to disprove syndrome characteristics of the model by classic clinical prescriptions, and evaluate the specificity and reliability of the model with macroscopic biological signs and symptoms.

METHODThe model characterized by Qi stagnation and blood stasis syndrome was established by injecting adrenaline into female SD rats and conducting unpredictable chronic stimulus such as reversal of day and night, swimming in cold water, thermal stimulation in oven, noise and tail suspension for two weeks. They were also orally administered with Xiangfu Siwu Tang, Shaofu Zhuyu Tang and positive control drug aspirin in groups. A comprehensive evaluation was conducted for the model on the basis of haemorheology, four blood coagulation indexes, four diagnostic information (digital imaging of tongue, paw and tail, temperature, weight, ingestion, electrocardiograph, and open filed test), and syndrome rating.

RESULTCompared with the normal group, the model group showed obvious changes in haemorheology, four blood coagulation indexes, animal behavior, weight, ingestion, syndrome rating and heart rate. Their tongue and paw pictures were analyzed with Photoshop 7.0, showing significant difference in red, green and blue percentage composition from the normal group. Groups given aspirin and Xiangfu Siwu Tang showed notable changes in haemorheology, four blood coagulation indexes, animal behavior, weight, ingestion, heart rate, syndrome rating, and red, green and blue percentage composition in tongue and paw pictures, whereas the group given Shaofu Zhuyu Tang showed no remarkable improvement.

CONCLUSIONThe evaluation system for the animal model with gynecological disease characterized by Qi stagnation and blood stasis syndrome is established to provide reference for studies on the evaluation system for qi stagnation and blood stasis syndrome models.
