본 연구는 골다공증유발 rat에 녹용추출물의 투여가 예방 및 치료효과에 미치는 영향을 구명하고자, 양측 난소를 적출한 후 골다공증이 유발된 rat에 암, 수녹용 추출물 525, 1,250 mg/kg을 투여했을 때 체중, 대퇴골의 중량, 장기중량, 골회분량의 측정 및 조직학적, 전자현미경적 검사 등을 실시하였다. 1. 골다공증유발 rat에 암, 수녹용 추출물을 투여했을 때 체중은 정상대조군에 비하여 유의한 증가를 나타냈다 (p＜0.05). 2. 골다공증유발 rat에 암, 수녹용 추출물을 투여했을 때 우측, 좌측의 femur 중량은 정상대조군에 비하여 감소하였다. 3. 골다공증유발 rat에 암, 수녹용 추출물을 투여했을 때 골회분량은 정상대조군에 비하여 약간 감소된 치를 나타냈으나 유의성은 인정되지 않았다. 4. 골다공증유발 rat에 암, 수녹용 추출물을 투여했을 때 간과 비장 및 신장의 각각 정상대조군에 비하여 감소된 치를 나타냈다. 5. 골다공증유발 rat에 암, 수녹용 추출물을 투여했을 때 조직학적 및 전자현미경적 소견은 정상대조군에서는 소주골간의 연결이 비교적 잘 유지되어 있고 골소실을 발견할 수 없었으나 난소적출군은 정상군에 비하여 소주골이 가늘어졌거나 소주골간 연결부분의 대다수가 끊어져 골양이 많이 소실되었음이 관찰되었으며, 녹용처리군에서는 소주골의 형태가 굵고 연결부분이 잘 유지되어 정상군과 유사한 소견이 관찰되었다. 위의 결과들에서 암, 수녹용 추출액은 난소제거후의 골소설을 억제하므로 골다공증의 예방과 치료에 효과가 있는 것으로 판단된다.

In this study, we investigated the preventive and therapeutic effects of antler-extract for osteoporosis. Rats were ovariectomized bilaterally and were fed up with Ca- and P-free diet in order to induce osteoporosis. Body weight, organ weight, the weight of femur and bone ash quantity were examined for 5 weeks. We also performed histological and electronical microscopic examinations. 1. After adminstration of female and male antler extract to osteoporosis-induced rats at the doses of 625 and 1250 mg/kg, respectively, the body weights were significantly increased compared with those of normal control group's which was 230.2:t2.3-281.0:t2.5g (p＜0.05). 2. The weights of both right and left femur of osteoporosis-induced rats, administered with female or male antler-extract, little decreased compared with those of normal control group. 3. The bone ash quanties of femur of osteoporosis-induced rats, administered with female or male antler-extract, little decreased compared with those of normal control group. 4. The weights of liver, spleen, and kidney of osteoporosis-induced rats, administered with female or male antler-extract, decreased compared with those of normal control group. 5. Histological and electronic microscopical findings were (1) that in normal control rats the connectional of lacunae appeared well and were without loss of bone mineral, (2) that in ovariectomized rats the connections of lacunae were mostly broken and were with loss of bone mineral compared with those of normal control rats, (3) that in osteoporosis-induced rats, administrated with female or male antler-extract, the shape of lacunae and the connections of them were similar to those of normal control rats. These findings suggest a possible protective and therapeutic effects of female or male antler extract against bone loss in ovariectomized rats.
