Abstract

Immunomodulating effect of Salicornia herbacea extract on the mouse splenocytes was investigated. Crude S. herbacea polysaccharide extract (CSP) and other kinds of fine S. herbacea polysaccharides (SPI and SPII) were prepared from S. herbacea by hot water extraction and further ultrafiltration and gel filtration chromatography. In vitro experiment, the mouse splenocytes and separated T cells were treated with CSP, SPI or SPII (0.5, 1, 2, 4 mg/ml). In vivo experiment, three different S. herbacea extracts were orally administrated everyday for one week. For the basic data, body weight and physiological parameters such as organ weight and spleen index were observed. The proliferation of the cells was used as an index for immunemodulating activity and the effect of proliferation was evaluated using MTS assay. The CSP, SPI and SPII directly induced the proliferation of splenocytes and separated T cells in a dose-dependent manner. In results, the proliferation was more increased in the SPI and SPII treated cells than in the CSP treated cells. The best proliferation was shown in the splenocytes cultured with SPI at the concentration of 4 mg/ml for 24 hr. The proliferation of splenocytes and separated T-cells was higher (3.2 and 3.5 times, respectively) than the control. Moreover, when the mouse splenocytes were treated with mitogen, the efficient proliferation was shown in the splenocytes cultured with SPI. In conclusion, polysaccharides from S. herbacea showed a substantial immunomodulating activity in the mouse immune cells.

함초(Salicornia herbacea)는 염습 지대에서 자생하는 명아주과에 속하는 일년초 식물로서 우리말로는 퉁퉁마디라고 불리우며, 식용과 약용으로 이용되고 있다. 건조된 함초로부터 열수 추출을 하여 조추출물(CSP)을 얻었으며, 조추출물을 한외 여과 및 gel 여과를 통해 다당체I(SP I)과 다당체 II(SP II)를 얻었다. 이렇게 얻은 함초 추출물들은 마우스 면역 조절 활성을 확인하는데 사용되었고, 실험은 시험관 내 실험과 생체 내 실험으로 나누어 진행되었다. 시험관 내 실험에서는 $7{\sim}8$주 된 Balb/c 마우스로부터 비장 세포와 T 세포를 분리하여 시료를 농도별(0.5, 1, 2, 4 mg/mL)로 처리한 후 일정 시간 배양하여 MTS assay를 통해 세포 증식능을 확인한 결과, 비장 세포와 T 세포에서 각각 4 mg/mL 농도로 24시간 배양한 경우 시료를 처리하지 않은 대조군에 비하여 SP I이 3.2, 3.5배로 유의적인 세포 증식 활성을 나타내었다. 생체 내 실험에서는 $7{\sim}8$주 된 Balb/c마우스를 대조군과 투여군으로 나누어 7일 동안 경구 투여를 실시하였는데, 실험 종료 후 비장 세포를 적출하여 mitogen을 이용한 세포 증식능을 확인한 결과, SP I을 경구 투석한 비장 세포가 가장 높은 세포 증식능을 보였다. 즉, 함초로부터 조추출물과 다당체를 획득하여 이들에 대한 면역 활성능을 확인한 결과, 조추출물과 다당체에서 면역 세포 활성 증강 효과를 보였는데, 조추출물보다 다당체에서 더 높은 활성을 보였다. 따라서 함초 다당체는 면역 증강 활성을 가진 바이오 헬스 소재로 개발될 수 있을 것으로 기대된다.
