Background
Over the years, Alisma Shugan Decoction (ASD), because of its potent anti-inflammation activity, has been used in traditional Chinese medicine (TCM) for treatment of many inflammation-associated disorders including those of the heart, blood vessel and brain.
Conclusion
In conclusion, the present study provides preclinical evidence for the use of ASD as an efficacious therapeutic option in cases of chemical-induced liver damage and/or fibrosis. Further large-cohort validation of these findings is warranted.
Methods
Herein, we examined the probable therapeutic effect of ASD in carbon tetrachloride (CCl4)-induced liver injury and fibrosis mice models.
Results
Our results demonstrate that ASD dose-dependently reduced the fibrosis-related increased collagen deposition secondary to liver tissue exposure to CCl4. Data from our biochemical analyses showed significantly less liver damage biomarkers including ALT, AST and hydroxyproline in the ASD-treated samples, suggesting hepato-protective effect of ASD. Furthermore, we demonstrated that treatment with ASD significantly reversed CCl4-induced elevation of TNF-α, IL-6, IL-1β and MP-1. Interestingly, NF-κB signalling, a principal regulator of inflammation was markedly suppressed by ASD treatment. In addition, treatment with ASD deregulated stress signalling pathways by suppressing the expression of markers of unfolded protein response, such as ATF6, IRE and GRP78.
