Abstract:
Aim To study the effects of total saponins of Panax japonicus(TSPJ) on liver inflammation of natural aging rats.Methods The experimental rats were allocated into seven groups (twelve rats in each group): three months group, nine months group, fifteen months group, twenty-four months group, and TSPJ low-, mid-and high-dose groups(10, 30, 60 mg·kg-1).When the rats were eighteen months old, the TSPJ low-, mid-and high-dose groups of rats were given lavage treatments with TSPJ 10,30, 60 mg·kg-1 respectively until twenty-four months.During lavage, we stopped a day every week for six consecutive months.HE staining was used to observe the pathological morphological changes.Western blot was utilized to test IL-1β and TNF-α protein expressions.RT-PCR method was adopted to test IL-1β, IL-6, IL-12, IL-17α, TNF-α, IFN-γ mRNA expressions.Results HE staining observation showed that as the rats grew older the hepatic cord and sinusoid were arranged in more severe disorder, and the fat vacuole and inflammatory cells were increased significantly.While every dose group of TSPJ could improve these pathological changes distinctly.The IL-1β, TNF-α protein and IL-1β, IL-6, IL-12, IL-17α, TNF-α, IFN-γ mRNA expressions were increased gradually as the rats grew older, and every dose group of TSPJ could reduce their expressions to some extent.Conclusion TSPJ could protect the aging rat liver to some extent by inhibiting the liver inflammation.
