Background: Consumption of herbal flavonoids instead of chemical drugs has increased in recent years due to fewer side effects and affordability. In this study, the effect of apigenin was investigated on inflammation induced by lipopolysaccharide in male rat's serum by measuring the pro-inflammatory cytokines, i.e., IL-1β, IL-6, and TNF-α.Methods: 90 male Wistar rats weighing 200 ±2 grams were used and divided into control, sham (solvent), and positive control (dexamethasone 15 mg/kg. ip), and 3 experimental groups which received 5, 15 or 30 mg/kg of apigenin, intraperitoneally. In 30 minutes after interventions, lipopolysaccharide (LPS) [30 μg/kg. ip] was injected. Then, at 4, 12- and 24-hour intervals, rats were anesthetized, and blood samples were prepared intracardially. Samples were centrifuged, and serums were separated and stored at -80 ° C. Measurement of IL-1β, IL-6, and TNF-α were conducted by the enzyme-linked immunosorbent assay (ELISA) method. Data were analyzed using the SPSS software version 19.Results: Pre-injection of apigenin at 5 mg/kg dosage were reduced TNF-α and IL-1β levels at 24-hours after LPS injection, compared to control (for both P P ) and 24- (P ) hours, IL-1β level at 24-hours (P ), and IL-6 level at 4- (P ) and 24- (P ) hours after LPS injection.Conclusions: Apigenin reduces proinflammatory cytokines in serum in acute inflammation induction. This impact is close to the dexamethasone effect as an anti-inflammatory steroid drug. |
