  • The immunomodulating effect of Salicornia herbacea polysaccharides on BALB/c mice splenocytes was investigated. Crude (CS) and fine polysaccharide (PS) extracts with potential biological activity were prepared from S. herbacea. For in vitro experiments, splenocytes and separated T cells were treated with CS and PS (0.5, 1, 2, and 4 mg/mL). For in vivo experiments, the CS and PS were orally administered to BALB/c mice every day for 2 weeks. For basic data analysis, physiological parameters were recorded. Cell proliferation of splenocytes and T cells was used as an index for immunomodulating activity. The proliferation of splenocytes and separated T cells was 3.2 and 3.5 times higher than the control, respectively. Moreover, when splenocytes were treated with mitogen, the highest proliferation rate was observed in splenocytes cultured with PS. Interestingly, the stimulative activity of PS was more strongly exerted through $CD4^+$ T cells than through $CD8^+$ T cells.

  • Glycosaminoglycans(PT -Gag) were isolated from the porcine testis. From the PT -Gag, we obtained two different types of Gag fractions using Dowex macro porous Resin MSA-1 column, PT -Gag-1.5% NaCl and PT -Gag-16% NaCl. Various biological activities of the GAGs were examined in aspect of anticoagulant and immunomodulating activity. The anticoagulant activity of the GAGs was evaluated by activated partial thromboplastin time (aPTT ) assay and thrombin time (TT) assay. The GAGs of porcine testis markedly incresed the clotting times of both of aPTT and TT. showing that PT-Gag-16% NaCl was more effective than PT-Gag-1.5% NaCl. The immunomodulating activityof the GAGs was examined in relation to regulation of xytoxine prodution of murine peritoeal maerophages. Taken together. GAGs isolated from porcine testis possess bilolgical functions such as anticoagulant and immunomodulating activity.

  • Objectives: This study was designed to examine the anti-cancer activity by innate immunomodulating and anti-inflammatory effects of liriopis tuber water extract (LPE). Methods: Cell cytotoxicity was tested with 4T1 mouse mammary carcinoma cells, spleen cells, macrophage, and RAW264.7 cells. To investigate innate immunomodulating effects of LPE on macrophage, we measured tumor necrosis factor-alpha (TNF-α), interleukin-12 (IL-12), and interleukin-10 (IL-10). To investigate innate immunomodulating effects of LPE on RAW264.7 cell, we measured TNF-α, interleukin-6 (IL-6). In addition, TNF-α and nitric oxide (NO) induced by lipopolysaccharide (LPS) were measured after treating with LPE to observe innate immunomodulating effect of LPE on RAW264.7 cell. Also, mitogen-activated protein kinase (MAPK) and nuclear factor κB (NF-κB) were examined by western blot analysis. Results: In an in vitro cytotoxicity analysis, LPE affected tumor cell growth above specific concentration. As compared with the control group, the production of TNF-α, IL-12, and IL-10 were increased in macrophage. As compared with the control group, the production of TNF-α and IL-6 were increased in RAW 264.7 cell. The expression of TNF-α and NO induced by LPS after treating LPE was decreased. In addition, treatment of RAW 264.7 cell with LPE increased the phosphorylation levels of p-extracellular signal-regulated kinase (p-ERK), p-Jun N-terminal kinase (p-JNK), and p-p38. Conclusions: LPE might have impact on the anti-cancer effect by activation of innate immune system and inflammation control.

  • Glycosaminoglycans (GAGs) were isolated from the porcine testis, and their immuno-modulating and anticoagulant activity was investigated. From anion exchange chromatography (Dowex Macropolous Resin) used for further isolation of porcine testis GAGs (PT-GAGs), two fractions (PT-GAG-1.5 and PT-GAG-16) eluted by different salt concentration were obtained. In immunomodulating activity test, PT-GAG-1.5, but not PT-GAG-16, significantly enhanced the growth of murine peritoneal macrophages. In addition, treatment with PT-GAG-1.5 induced the production of cytokines, interleukin-1$\beta$ (IL-1$\beta$), interferon-${\gamma}$ (IFN-${\gamma}$) and tumor necrosis factor-$\alpha$ (TNF-$\alpha$), from murine microphages. Unexpectedly, both of PT-GAGs had no effect on the growth of murine splenocytes. The anticoagulant activity of PT-GAG-1.5 and PT-GAG-16 was examined by activated partial thromboplastin time (aPTT) assay and thrombin time (TT) assay. Both of PT-kGAGs significantly increased the clotting times of aPTT and TT in a dose-dependent manner. The anticoagulant activity of PT-GAG-16 was found to be higher than that of PT-GAG-1.5. These results suggest that PT-GAGs possess biological activities such as immunomodulating activity and anticoagulant activity.

  • 인간의 체내에서 과량으로 생성된 활성산소가 자체 방어기전에 의해서 분해 혹은 소거되지 않는 경우에 이는 생체 조직 내 세포와 면역체계에 관련된 효소들을 손상시켜 암이나 면역질환과 같은 퇴행성 질환을 야기 시키는 것으로 알려지고 있다. 이에 본 연구에서는 고대 이집트 시대이래 지금까지 서구에서 약초 혹은 향초로서 사용되어온 13종 허브추출물에 대해서 유해산소 소거능을 검색하고 SRB assay 방법에 따라 두가지 암세포주(Hepa-lclc7, KB-3-1)와 정상세포주(L-929)에 대한 세포 독성을 조사하였다. 또한 이들에 의한 대식세포의 활성화와 같은 면역체계의 증강 유도 여부를 파악하기 위하여 NO test에 따라 대식세포의 활성화 정도를 간접적으로 측정하였다. 그 결과 13종류의 허브추출물에서 일반적으로 medicinal 허브로 분류되고 있는 eucalyptus, peppermint, mate, sage, thyme, yarrow 등의 수퍼옥사이드 소거능이 다른 허브들에 비해 상대적으로 강한 것으로 나타났다. 또한 이들은 Hepa-1c1c7, KB-3-1과 같은 암세포주 및 L-929와 같은 정상세포주에 대하여도 세포독성을 나타냈으며 이때 각각의 허브추출물에 의해 측정된 암세포주에 대한 $IC_{50}$ 값들은 정상세포주에 대한 $IC_{50}$ 값들보다 크거나 유사한 경향을 나타내어 암세포주에만 선택적으로 세포독성을 나타내지 않았다. 면역증강 활성실험에 있어서는 수퍼옥사이드 소거능이 다른 허브들에 비해 상대적으로 강한 6종류의 허브추출물 중에서 sage 만이 표준시료의 37% 정도의 활성을 나타내어 각 시료의 수퍼옥사이드 소거능과 면역증강 활성과의 연관성은 크지 않은 것으로 나타났다.

  • Recently many investigators have initiated searches for immunomodulating substances from natural food sources. Ginger (Zingiber officinale Roscoe) has been used as a raw material in many traditional preparations since the ancient time. This study was performed to investigate the immunomodulative effects of Zingiber officinale Roscoe in mice, using ex vivo experiments. In order to elucidate the immunomodulative effects of Ginger, water extracts of the plant were orally administrated into mice, and isolated splenocytes and macrophages were used as experimental model. In order to identify its ex vivo effect six to seven week old Balb/c mice were fed ad libitum on a chow diet and water extracts of ginger were orally administrated every other day for two weeks at two different concentrations (50 and 500 mg/kg b.w.). After preparing the single cell suspension, the proliferation of splenocytes was determined by MTT assay. The result of ex vivo study showed that the highest proliferation of splenocytes and macrophage activatation was seen in the mice orally administrated at the concentration of 500 mg/kg b. w. of ginger water extracts. In conclusion, this study suggests that ginger extracts nay enhance the immune function by regulating the splenocyte proliferation and cytokine prodution capacity by activated macrophages in mice.

  • 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.
