Abstract: On the basis of New fertilitypromoting intrauterine infusion liquid (NFPL), 3 additive prescriptions were composed respectively by adding drugs of reducing fever, promoting blood circulation and replenishing Qi. Four prescriptions were used to treat rabbit experimental endometritis by intrauterine infusion and their curative effects were compared according to clinical pathological changes of symptom, uterine morphology, micro-and ultra-structure of endometrium after administration. The results showed that NFPL possessed significant curative effect. Clinical symptom of affected rabbits in NFPL group was abated, uterine perimeter and index decreased, endometrial inflammation extinguished and trauma recovered quickly. Prescription 2 was of better efficacy and could be used as an alternative of NFPL.
