본 실험에서는 녹용 약침액의 항 골재흡수 속성을 조사하였다. PTH, $1,25(OH)_2D_3$와 IL-1을 각각 골재흡수 인자로 사용하여 생쥐의 두개골에서 osteoblast 세포를 격리, 배양, 그리고 자극시켰을 때 collagenolysis의 증가를 보였다. 두 가지를 동시에 사용한 결과, IL-1은 골재흡수성을 촉진시키고 재 흡수력을 생산하였다. In vitro에서의 세포독성 결과는 $1-200{\mu}g/ml$의 녹용 약침액 농도 분포에서 무세포독성을 보였다. 또한 녹용 약침액은 생쥐의 두개골 골아세포 내에서 PTH (2 unit/ml), IL-$1{\alpha}$ (1 ng/ml), $1,25(OH)_2D_3$ (10 ng/ml), IL-$1{\alpha}$ 및 IL-$1{\beta}$로 인해 유발된 collagenolysis에 대해서 대항하는 보호활동성을 나타내었다. 녹용약침액은 IL-$1{\alpha}$ 와 IL-$1{\beta}$로 인해 유발된 collagenolysis에 대항하는 보호활동성을 지녔다. DAS는 IL-$1{\alpha}$와 IL-$1{\beta}$로 인해 촉진된 골재 흡수력을 억제하는 효과를 보였다. 이와 같은 결과는 녹용약침액이 골다공증과 연관된 질환에 대해서 매우 안정적인 임상적 사용이 가능한 것을 관찰할 수 있으므로 추후 이와 관련한 지속적인 연구가 필요할 것으로 사료되었다.

Anti-bone resorption properties of the Korean herbal medicine, CEDR, which is comprised 5 herbs of [Drynariae Rhizoma, Loranthi Ramus, Cibotii Rhizoma, Amydae carapax, Psoraleae semen], were investigated. Mouse calvarial osteoblast cells were isolated and cultured. Mouse osteoblasts, which were stimulated by PTH, $1,25(OH)_2D_3$, $TNF-\alpha$ and IL-1 as bone resorption agents, showed increased collagenolysis by producing the active gelatinase. IL-1 in stimulating bone resorption was examined using fetal mouse long bone organ culture. IL-1 stimulated bone resorption and produced marked resorption when present simultaneously. The results of in vitro cytotoxicities showed that CEDR extracts have no any cytotoxicities in concentrations of $1-60{\mu}g/ml$ and furthermore there is no any cytotoxicity even in concentration of $120{\mu}g/ml$ on mouse calvarial bone cells. CEDR extracts had protective activity against PTH (5 units/ml, or $IL-1{\alpha}$ (1 ng/ml) or $TNF-\alpha$ or $1,25(OH)_2D_3$ (20 ng/ml), $IL-1{\alpha}$ and $IL-1{\beta}-induced$ collagenolysis in the mouse calvarial cells. Pretreatment of the CEDR extracts for 1 h, which by itself had little effect on cell survival, did not enhance the collagenolysis, nor significantly reduced the collagenolysis by pretreatment. Furthermore, the medicinal extracts were shown to have the protective effects against collagenolysis induced by $IL-1{\alpha}$ and $IL-1{\beta}$. Pretreatment of the extracts for 1 h significantly reduced the collagenolysis. Interestingly, the CEDR extracts were shown to have the inhibiting effects against gelatinase enzyme and processing activity induced by the bone resorption agents of PTH, $1,25(OH)_2D_3$, $TNF-\alpha$, $IL-1{\beta}$ and $IL-1{\alpha}$ with strong protective effect in pretreatment with the extracts. CEDR extracts were shown to have the inhibiting effects against $IL-1{\alpha}-$ and $IL-1{\beta}-stimulated$ bone resorption and the effect of the pretreatment with a various concentrations of the medicinal extracts were significant. These results indicated that the CEDR extracts are highly stable and applicable to clinical uses in osteoporosis.
