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- κ B) level, polymorphonuclear (PMN) cells level, interleukin-1 β (IL-1 β ) 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-1 β and TNF- α levels and the expressions of ICAM-1, COX-2, and iNOS NF- κ B 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.
在本研究中,我们研究了姬松茸水溶性多糖(WSP-AbM)对去卵巢骨质疏松大鼠的抗炎活性。大鼠口服 WSP-AbM(200mg/kgBW)8 周。随后通过酶联免疫吸附试验(ELISA)和免疫组织化学法测定血清丙二醛(MDA)水平、总抗氧化状态(TAOS)、核因子-κB(NF-κB)水平、多形核(PMN)细胞水平、白细胞介素-1β(IL-1β)水平、诱导型一氧化氮合酶(iNOS)水平、肿瘤坏死因子-α(TNF-α)水平、细胞间黏附分子-1(ICAM-1)和环氧化酶-2(COX-2)。与 OVX 大鼠相比,WSP-AbM 给药显著降低了血清 IL-1β 和 TNF-α 水平以及 ICAM-1、COX-2 和 iNOS NF-κB 的表达。WSP-AbM 给药还显著减少了 PMN 浸润。综上所述,我们观察到 WSP-AbM 补充对骨质疏松症模型具有抗炎作用。
