[Method] Healthy Kunming mice pretreated with methylprednisolone for the purpose of immunity decrease were randomly divided into 15 groups, and each mouse was intraperitoneally inoculated with 1.0 ×104 N. caninum. Four hours later, the mice were gavaged with various Chinese medicines. Seven days post-administration, eyeball blood sampling was conducted and the serum was used for antibody level detection with ELISA method. [Result] Four among the 15 Chinese medicines showed lower antibody positive rates. [Conclusion] Scutellaria baicalensis, Stemona sessilifolia, Gastrodia elata and Coptis chinensis could enhance the immunity level of mice infected by N. caninum.展开更多
