Methods Infant Wistar rats were infected intranasally with M. pneumoniae once a day for four days. In the treatment groups, Xiaoer Feire Kechuan oral solution was administered daily for four days beginning from the day of infection. On day 5, blood of the rats was collected, and blood routine and biochemistry indexes were measured. All rats were sacrificed, and the weight of brain, heart, liver, and kidney was measured to calculate the organ indexes. The GM1 and GALC-Ab content in brain tissue was determined by ELISA. Pathological changes in the brain, heart, liver, kidney, and cerebellum were observed by HE staining. Results Blood routine indexes fluctuated within the normal range in the infection control group and in three of the Xiaoer Feire Kechuan oral solution groups. The serum LDH, CK, and CRE in all three Xiaoer Feire Kechuan oral solution groups were distinctly lower than those in the infection control group (P < 0.01, P < 0.05). Rat brain index and GALC-Ab content in the brain tissue showed an increase in infection control group. In the Xiaoer Feire Kechuan oral solution groups, the GALC-Ab content in brain tissue was decreased significantly. The heart, liver, and kidney tissues showed mild pathological changes in the infection group, which were reversed by Xiaoer Feire Kechuan oral solution treatment. Conclusions The extrapulmonary injury induced by M. pneumoniae in infant Wistar rats was significantly inhibited by Xiaoer Feire Kechuan oral solution.展开更多
