Free Radical Scavenging Capacities and Alleviating Actions of Polysaccharides Extract of on Methylprednisolone-Induced Immunodepression in Rats.

BACKGROUND

Natural products have been said to show immunomodulatory and antioxidant activities. The research study was aimed to assess the immunomodulatory and free radical scavenging activities of crude polysaccharide from dry mushroom fruiting bodies of .

MATERIALS AND METHODS

Hot water extract of polysaccharide extract of was prepared and tested in white albino Wister rats for its immunomodulatory activities effect on methylprednisolone-immunosuppressed animals. In addition, the radical scavenging activity of the polysaccharide was evaluated using nitrite and hydrogen peroxide.

RESULTS

The result of the study showed that the polysaccharide increases the phagocytic index, energy metabolism of macrophages, spleen index, and nitric oxide in a concentration-dependent manner in immunosuppressed animals. Also, it was observed that the extract increased dose-dependent total oxidative stress and thymus index. Finally, the crude polysaccharide-rich extract showed nitrite and hydrogen peroxide scavenging activity in a concentration-dependent manner.

CONCLUSION

Polysaccharide-rich extract possesses immunomodulatory and antioxidant properties.
