ABSTRACT
This study was aimed to observe the therapeutic effect onendometritis rat model by Gui-Zhi Fu-Ling (GZFL) capsuleand its mechanism. Endometritis rat model was replicated. After 15 days, rats were randomly divided into six groups, which were the sham operation group, model group, lowdosage (0.5 g·kg-1) of GZFL capsule group, middle dosage (1.0 g·kg-1) of GZFL capsule group, large dosage (2.0 g·kg-1) of GZFL capsule group, and Fu-Ke Qian-Jin (FKQJ) capsule (1.2 g·kg-1) group. After 28-day intragastric administration of medication, pathological changes of endometrium were observed. The contents of monocyte chemoattractant protein-1 (MCP-1), interleukin-1β (IL-1β), interleukin-10 (IL-10) were determined in blood serum.The expression of TGF-β1 in endometritis rats were measured by immunohistochemistry. The results showed that GZFL capsule canobviously alleviate the pathologi-cal damage of endometrium in rat model. In comparison with sham operation group, the serum IL-10 content in the model group was significantly decreased, contents of MCP-1and IL-1β were significantly elevated; the TGF-β1 pro-tein expression was significantly elevatedin the uterus tissues. After the treatment of GZFL capsule, compared with the model group, the serum IL-10 was obviously elevated in the treatment group. The contents of MCP-1 and IL-1βwere obviously decreased. The expression of TGF-β1 in the uterus tissues was obviously decreased. It was concluded that GZFL capsule had treatment effect on endometritis. The mechanism may be related to the regulation of inflam-matory cytokines.
