Osteoporosis is the most prevalent metabolic bone disease and is characterized by diminished bone strength predisposing to an increased risk of fracture. We investigated the effects of the extract from Acyranthes Radix on the progress of bone loss in ovariectomized rats for 6 weeks. Female Sprague-Dawley 40 rats of 3-4 weeks, weight 200 ${\pm}$ 10g were divided into two groups including the sham operation group(8 rats) and ovariectomy group(32 rats). The dose-dependent effect of Acyranthes Radix extract on bone mineral density and biochemical testing was assessed in ovariectomized rat. Body weights were increased in all groups was higher in experimental group than sham operation group. The level of bone mineral density, GPT, and serum P concentration, ALP were increased experimental group, but a little increase in sham operation group at same period. This longitudinal study result made conclusion that Acyranthes Radix extract treatment appeared to improve the osteoporosis delaying the progression to the osteoporotic process in rats.

Purpose: We investigated the effects of the combined therapy in rats with rheumatoid arthritis induced by type II collagen for 28 days, which consisted of the oral administration of the AR and EA applied to zusanli acupoint(ST36). Methods: Normal group was oral administered with 0.9% NaCl $0.5\;m{\ell}/day$ to normal rats. Control group was oral administered with 0.9% NaCl $0.5\;m{\ell}/day$ to arthritic rats. Group I was oral administered with AR 500 mg/kg $0.5\;m{\ell}/day$ to arthritic rats. Group II was given 2 Hz EA of ST36 in the test group for 30 min/day to arthritic rats. Group III was oral administered with AR 500 mg/kg $0.5\;m{\ell}/day$ and 2 Hz EA of ST36 in the test group for 30 min/day to arthritic rats. We Observed effect of the histopathological changes by H&E stain of liver, kidney, knee joint and ELSIA of cytokines($TNF-{\alpha}$). Results: 1. The vacuolization of liver tissue was decreased in group I, II, III comparing with control group. 2. The glomerular sclerosis of kidney tissue was decreased in group I, II, III comparing with control group. 3. The erosion of arthritic site of knee joint tissue was decreased group I, II, III comparing with control group. In particular group III was the most effective comparing with group I, II on the histopathological view. 4. In the ELSIA test of $TNF-{\alpha}$ concentration, Control group significantly increased in the concentration more than group I, II, III. The rate of increase in concentration slowed down in group III more than group I, II(p<0.05). Conclusion: It is concluded that 500 mg/kg of AR extracts and EA have clear therapeutic effect on the rheumatoid arthritis.
