Abstract

Cham-dang-gui (Angelica gigas nakai) has been used in traditional Korean medicine to treat hemotological disorders. The purpose of this study is to investigate the hematological effects of water extracts of Cham-dang-gui in rats with anemia induced by iron-free diets. Rats were divided into two groups, a regular diet group (RD) and an iron-free diet group (FeD). The iron-free diet group was then subdivided into the following three treatment groups: saline (1.0 ml/kgBW/day, FeDS), Cham-dang-gui (1.0 g/kgBW/day, FeDA), and iron (iron succinylate 14 mg/kgBW/day, FeDFe) groups. Rats were fed an iron-free diet for 6 weeks to induce iron-deficient anemia, and subsequently underwent the treatments, during which they were fed an iron-free diet for 3 weeks followed by a regular diet for 3 weeks. Body weights of the iron-diet groups (FeDS, FeDA, FeDFe) were lower than that of RD group. The blood levels of Hgb, Hct, MCV, MCH and TIBC were significantly higher in RD and FeDFe groups than those of other groups. The water extract of Cham-dang-gui with iron-free diet has no hematological effects. A regular diet followed by iron-free diets significantly increased blood levels of Hgb, Hct, and MCH.

본 연구에서는 무철분식이로 철분결핍성 빈혈 유발을 시킨 흰쥐에게 3주간 무철분식이를 섭취시키면서 saline, 참당귀 추출물 및 철분보충제를 투여한 후, 무철분식이를 일반식이로 대체하여 다시 3주간 같은 처리를 한 후 혈액학적 빈혈지표를 조사하여 결과를 요약하면 다음과 같다. 1) 실험동물의 체중은 무철분식이군에서 일반식이군에서 보다 유의적으로 낮게 나타났다. 무철분식이로 인한 저체중은 참당귀 추출물과 철분 보충제에 의해서 회복되지 않았다. 2) 혈액분석 결과 무철분식이는 모든 혈액 빈혈지표를 저하시켰으며, 철분보충제의 투여는 헤모글빈, 헤마토크릿, 평균 혈구 부피, 평균 혈구혈색소, 평균 혈구혈색소 농도, 총철결합능력이 유의적으로 회복시켰다. 무철분식이와 함께 투여한 참당귀 추출물은 혈액지표를 개선시키지 못하였다. 한편, 일반식이와 함께 섭취하였을 경우, 헤모글로빈, 헤마토크릿, 평균 혈구부피, 평균 혈구혈색소, 평균 혈구혈색소 농도, 총철결합능력 모두 유의적인 회복효과를 보였으나 일반식이만을 섭취한 군에서도 같은 회복효과를 보였다. 결론적으로, 장기간에 걸쳐 철분 섭취가 불량할 경우, 체중증가가 지연되며 후에 철분을 보충할 경우에도 체중의 회복은 개선되지 않았다. 철분결핍으로 인한 저체중의 경우, 철분보충제의 복용은 체중을 만회시키지 못하였으나 혈액학적 빈혈 지표들은 회복시키는 것으로 나타났다. 철분결핍 빈혈에서 식이철분이 부족할 경우, 참당귀의 회복효과는 미비한 것으로 나타났다. 향후 철분결핍 빈혈의 치료를 위한 생약제의 다양한 작용을 밝히기 위하여서는 영양학적인 관점에서 체내 이용률에 관한 심도 깊은 연구가 이루어져야 할 것으로 사료된다.
