ABSTRACT
OBJECTIVE:
To investigate the effects of QKF on expression of amyloid-beta (Aß), interleukin-1 beta (IL-1ß), and glial fibrillary acidic protein (GFAP) using a rat model of AD. MATERIALS ANDMETHODS:
Fifty-six male Sprague-Dawley rats were randomly divided into seven groups (eight rats each) control group, sham-operated group, AD model group, groups of AD rats administered with low, medium, and high doses of QKF, and the donepezil group. AD was established by bilateral injection of ß-amyloid (Aß) 1-40 into the hippocampus. Two days after AD was established, drugs were administered by gavage. After 14 days of treatment, we used RT-PCR, Western blotting, and immunohistochemistry to measure the transcript expression and protein abundance of Aß, IL-1ß, and GFAP, and methenamine silver staining was used to detect amyloid protein particle deposition.RESULTS:
Compared to the control group, the rats from the AD model group showed significantly greater expression levels of Aß, IL-1ß, and GFAP. However, these differences in expression were abolished by treatment with QKF or donepezil.CONCLUSION:
QKF possesses therapeutic potential against AD because it downregulated Aß, IL-1ß, and GFAP in the hippocampus of AD rats. Future studies should further examine the mechanisms through which QKF produces its effects and the consequences of long-term QKF administration.
