Objective: To observe the synergistic protective effect of mangiferin combined with puerarin on spontaneously hypertensive rat (SHR) inflammation injury
in order to provide the experimental basis for clinical prevention and treatment of hypertensive patients with myocarditis induced by hypertension. Method: Eight rats with normal blood pressure rat (WKY) were taken as blank group (A); 72 10-week-old SHR rats were taken as the study object and randomly divided into model group (B)
benazepril group (C
10 mg·kg-1·d-1)
single mangiferin group (D
20 mg·kg-1·d-1)
single puerarin group (E
20 mg·kg-1·d-1)
mangiferin (20 mg·kg-1·d-1)+puerarin (10 mg·kg-1·d-1) group (F)
mangiferin (20 mg·kg-1·d-1)+puerarin (20 mg·kg-1·d-1) group (G)
mangiferin (20 mg·kg-1·d-1)+puerarin (40 mg·kg-1·d-1) group (H)
mangiferin (10 mg·kg-1·d-1)+puerarin (20 mg·kg-1·d-1) group (I)
and mangiferin (40 mg·kg-1·d-1)+puerarin (20 mg·kg-1·d-1) group (J). The rats were orally administered with drugs (10 mL·kg-1) for consecutively two months. They were fasting for 12 h before being put to death. The morphology of myocardial tissues in SHR was observed under microscope. Immunohistochemical assay and enzymelinked immunosorbent assay (ELISA) were used to detect interleukin (IL)-6
IL-10 and tumor necrosis factor-α(TNF-α). Result: Heart tissues of rats of each group showed no significant morphological change; immunohistochemistry and ELISA results showed that compared with the model group
each drug treated group showed decreases in myocardial IL-6
IL-10
TNF-α levels to varying degrees (P < 0.05
P < 0.01). Conclusion: Mangiferin combined with puerarin have no significant effect on morphology of heart tissues of SHR
but can down-regulate abnormal elevation of inflammatory cytokines IL-6
