Abstract

The sap of the white birch is one of the most widely used herbal medicines to treat gastrointestinal tract, jaundice, and various periodontal diseases. The purpose of this study was to measure the effect of white birch sap on in vivo immune agents in mice. The treatment of white birch sap on the forced swimming test has been used as a screening model for new immune enhancement agents. The hematological examination was significantly different in neutrophil, lymphocyte, and monocyte counts between treatment and control groups. Moreover the white birch sap changed the phagocytic index, immobility duration time, and leukocyte counts in mice.

면역증진기능성 식품으로서 자작나무 수액의 개발 가능성을 확인하기 위하여 자작나무로부터 채취한 수액을 동결건조하여 이를 수컷 ICR mouse에 경구 투여한 후 탄소제거시험과 부동시간 측정을 통해 면역증진 효과를 살펴보았다. 탄소제거능 시험에서 500 mg/kg B.W.의 용량으로 자작나무 수액 동결건조물을 투여하였을 때 멸균생리식염수만을 투여한 대조군에 비해 유의성있는 (p<0.05) 탐식지수(phagocytic index)의 증가가 있었으며, 강제수영 부하시험(FST) 결과 부동시간(immobility time)은 2주간 500 mg/ kg B.W의 용량으로 시험물질을 투여한 동물에서 대조군의 부동 시간과 비교하여 유의적으로 감소하였다(p<0.05). 125, 250, 500 mg/kg의 용량으로 6주간 투여한 동물에서 대조군 보다 부동 시간이 감소하였다. 특히 250, 500 mg/kg 용량 투여군에서 통계적으로 유의한(p<0.05) 부동시간의 감소가 관찰되었으며, 혈액학적 검사결과 백혈구계 세포 수의 증가를 나타내었다.
