Anti-Inflammatory Activity of Water-Soluble Polysaccharide of Agaricus blazei Murill on Ovariectomized Osteopenic Rats

Abstract EN

In the present study, we investigated the anti-inflammatory activity of water-soluble polysaccharide of Agaricus blazei Murill (WSP-AbM) on ovariectomized osteopenic rats.

The rats were administered orally WSP-AbM (200 mg/kg BW) for 8 weeks.

Subsequent serum maleic dialdehyde (MDA) level, total antioxidant status (TAOS), nuclear factor kappa B (NF-κB) level, polymorphonuclear (PMN) cells level, interleukin-1β (IL-1β) level, inducible nitric oxide synthase (iNOS) level, tumor necrosis factor-α (TNF-α) level, adhesion molecule (ICAM-1), and cyclooxygenase-2 (COX-2) were determined by enzyme linked immunosorbent assay (ELISA) and immunohistochemistry, respectively.

WSP-AbM administration markedly (P<0.05) decreased serum IL-1β and TNF-α levels and the expressions of ICAM-1, COX-2, and iNOS NF-κB compared with OVX rats.

WSP-AbM administration alsomarkedly (P<0.05) decreased PMN infiltration.

In conclusion, we observed that WSP-AbM supplementation had anti-inflammatory effects in a model of osteoporosis disease.
