Effects of Lonicera Japonica flavone on immunomodulation in mice / 中国应用生理学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study immunomodulating activity of Lonicera Japonica flavone by investigating immune enzymatic activity of serum and antoxidized activity of lymphoid organs in mice.</p><p><b>METHODS</b>Fifty KM mice were randomly divided into control group, model group, low dose group, middle dose group and high dose group(n = 10), respectively. And low dose group, middle dose group and high dose group were given Lonicera Japonica flavone with 100 mg/kg, 200 mg/kg and 400 mg/kg every day, respectively, while control group and model group were administered with NS. After continuously giving drug 7 weeks, other groups were injected with Dexamethasome (Dex 25 mg /kg) for 3 days by subcutaneous injection, but the control group were treated with NS. And after giving Lonicera Japonica flavone 1 week simultaneously, organ indexes , the activity of acid phosphatase (ACP), alkaline phosphatase (AKP) and lysozyme (LSZ) in serum , and the content of monoamine oxidase (MAO), total antioxidant capacity (T-AOC), total superoxide dismutase (SOD) and malondialdehyde (MDA) in lymphoid organs in mice were tested, respectively.</p><p><b>RESULTS</b>Lonicera Japonica flavone could significantly improve the organ indexes, and significantly improve the activity of ACP, AKP and LSZ in serum, and significantly improve the contents of T-AOC and SOD, but reduce that of MAO and MDA in lymphoid organs in immunosuppressed mice.</p><p><b>CONCLUSION</b>Ionicera Japonica flavone can significantly improve the activity of immune enzyme in serum and the antioxidized activity of lymphoid organs in mice. It suggests that Ionicera Japonica flavone has a good immunomodulatory effects.</p>
