title: [Effects of serum containing oral liquid of Guilu-Erxian on the therapy of osteoporosis at the cellular level].
abstract: This study sought to assess the effects of serum containing Guilu-Erxian (GLEX) on treating osteoporosis at the cellular level. First, Enzyme-digestion was used to obtain osteoblasts from newborn SD rats. Alkaline phosphatase staining was used to identify osteoblasts. The proliferation and the secretion of Insulin Like Growth Factor-1 (IGF-1) of osteoblasts were examined. Second, osteoclasts were generated by inducing bone marrow cells of SD male rat (6-9 weeks) with 1,25(OH)2D3. The osteoclasts were identified through tartrate-resistant acid phosphatase (TRAP) staining. Bone pits of osteoclasts were observed through Electron Scanning Microscope. At the same time, TRAP(+) cells with more than two nuclei and TRAP activity of osteoclasts were examined. Last, serum containing Guilu-Erxian was made through serum pharmacology. And we observed the effects of serum containing Guilu-Erxian on the function of osteoblasts and osteoclasts. We found that high doses of serum containing Guilu-Erxian had obvious effects on stimulating the multiplication and capability of secreting IGF-1 of osteoblasts cultured in vitro. Middle doses obviously inhibited the formation of osteoclasts and bone pits; TRAP activity of osteoclasts was also lowered clearly. This study indicated that Guilu-Erxian has positive effects on treating osteoporosis.
