Abstract
Abstract We evaluated the anti-osteoarthritic effects of deer bone extract on articular cartilage damage by using micro-computed tomography (micro-CT) in monosodium iodoacetate (MIA)-induced osteoarthritis (OA) in rats. Male Wistar rats (6 weeks of age) were randomly divided into 5 groups (10 rats/group): sham control (SC; PBS injection+PBS 1 mL treatment); negative control (NC; MIA injection+PBS 1 mL treatment); positive control (PC; MIA injection+250 mg/kg glucosamine sulfate/chondroitin sulfate mixture treatment); low dose (LDB; MIA injection+250 mg/kg deer bone extract treatment); and high dose (HDB; MIA injection+500 mg/kg deer bone extract treatment). After 50 days of treatment, we observed that the administration of deer bone extract protected against bone destruction and reduced the number of erosion lacunae. When deer bone extract was administered, the trabecular thickness distribution (Tb.Th) (LDB: 75.9 μm, HDB: 80.7 μm vs. NC: 48.0 μm) and the trabecular bone volume fraction ratio (BV/TV) (LDB: 43.8%, HDB: 48.2% vs. NC: 39.1%) were significantly restored. Additionally, the trabecular separation (Tb.Sp) increase caused by MIA was decreased significantly with the administration of deer bone extract (LDB: 73.4 μm, HDB: 81.2 μm vs. NC: 112.0 μm). We concluded that the oral administration of deer bone extract effectively relieved the morphological changes induced by MIA injection in an animal model.

    Deer bone extract has the potential to relieve the discomfort or the articular cartilaginous damage associated with osteoarthritic (OA) and may be useful as a natural supplement for OA treatment without serious side effects. We analyzed the expression of pro-inflammatory cytokine and cartilage-related genes in monosodium iodoacetate-induced OA rats. Increases in the levels of serum... [Show full abstract]

      BACKGROUND/OBJECTIVES We investigated the anti-osteoarthritic effects of deer bone extract on the gene expressions of matrix metalloproteinases (MMPs) and collagen type II (COL2) in interleukin-1β-induced osteoarthritis (OA) chondrocytes. MATERIALS/METHODS Primary rabbit chondrocytes were treated as follows: CON (PBS treatment), NC (IL-1β treatment), PC (IL-1β + 100 µg/mL glucosamine... [Show full abstract]

        We examined the thermal stability of yeast hydrolysates before and after ultrafiltration (UF) in vitro, and the anti-obesity activity of yeast hydrolysates before and after heat treatment in vivo. Yeast hydrolysate after UF showed significantly higher thermal stability than before UF. Yeast hydrolysates before and after UF showed 3 and 4 thermal transition peaks in their thermograms,...

          The aim of this study was to investigate the effect of deer bone oil extract (DBOE) on lipopolysaccharide (LPS)-induced inflammatory responses in RAW264.7 cells. DBOE was fractionated by liquid–liquid extraction to obtain two fractions: methanol fraction (DBO-M) and hexane fraction (DBO-H). TLC showed that DBO-M had relatively more hydrophilic lipid complexes, including unsaturated fatty... [Show full abstract]
