해바라기를 주원료로 한 복합조성물인 해바톤(HYE-BATON, (주) 새벽을여는사람들)의 면역활성 증진효과와 당뇨 및 지질대사에 미치는 영향을 분석하였다. 시험관 내에서 HYEBATON을 첨가하여 먼역세포를 배양한 결과 면역세포가 현저하게 활성화되었다. 생쥐에 HYEBATON을 투여한 결과 세포 매개성 면역반응이 증진되었으며, 암세포 이식 생쥐에서 종양의 생장을 억제시켜 생존기간을 연장시키는 경향을 보였다. 또한, HYEBATON이 혈당과 지질 대사에 미치는 영향을 흰쥐에서 살펴보았다. 쥐를 정상식이군, streptozotocin (STZ) 투여에 의한 당뇨군, 고지방식이군으로 나누어 HYEBATON을 7주간 투여하였다. 경구포도당 내성 검사에서 HYEBATON은 당뇨군의 증가된 공복시 혈당을 감소시켰으며, 경구로 포도당을 투여 시에도 당뇨군의 혈당을 계속 낮게 유지시켰다. HYE-BATON 이 지질대사에 미치는 영향을 살펴본 결과, HYE-BATON은 정상식이군, 당뇨군, 고지방 식이군의 혈중 및 간의 콜레스테롤과 지질의 양을 유의성 있게 감소시키거나 혹은 감소시키는 영향으 ?보였다. 한편, 시험관내 유전독성시험 및 생지의 급성독성시험에서 HYE-BATON은 안전한 것으로 평가되었다. 이러한 결과로 보아 HYEBATON은 면역활성 증진효과 뿐만아니라 당뇨 쥐의 혈당 및 지질대사 개선효과를 보였으므로, 면역증징 및 당뇨와 지질대사 개선을 위한 기능성 식품으로서 활용이 기대된다.

This study was performed to investigate the increasing of immune activities from Centella asiatica L. Urban by several solvent extraction with ultrasonification process. Ethanol extracts at $60^{\circ}C$ and associated with ultrasofication showed more 15% yield than normal $100^{\circ}C$ water extracts. And ethanol extracts showed higher yield than water extraction at each process. It can be concluded that yield due to polarity of compound in C. asiatica from HPLC peak. All of extracts from C. asiatica revealed lower cytotoxicity than 32%. The ethanol extracts with ultrasofication showed higher promotion on human B and T cell growth, about 10% compared to the control. The secretion of IL-6 and TNF-a was also enhanced as $4.86\;{\times}\;10^{-4}\;pg/cell$ and $5.73\;{\times}\;10^{-4}\;pg/cell$ each, by the addition ethanol extracts with ultrasonification to T cell. NK cell activation was improved up to 10% higher than the control, through adding the samples. It can be concluded that the ethanol extracts from C. asiatica has higher immune activities followed by ultrasonification process, possibly, by higher yield than conventional extraction process.

상황버섯은 오랜 역사와 전통이 있는 소재로서 폴리페놀류가 함유되어 있어 항암, 혈중콜레스테롤 저하, 혈압강하 등의 약리효과가 있는 것으로 알려져 있다. 본 연구에서는 in vivo 실험을 통해 CPA (Cyclophosphamide)로 유도된 면역저하 마우스 모델에서 상황버섯 투여 농도에 따른 cytokine 활성 효과를 확인하여 상황버섯의 면역 증진 효과를 평가하고, 유효한 농도를 선정하여 시제품을 제작하고자 하였다. 연구결과, 림프기관 장기 무게(흉선, 비장, 악하림프절)와 혈청과 비장의 cytokine이 CPA군(CPA control)에 비해 상황버섯 추출물 투여군에서 유의적으로 증가하였다. 또한 실험을 퉁해 선정한 유효한 농도인 50 mg/kg의 농도로 시제품을 제작하였으며, 상황버섯 특유의 떫은 맛을 감쇄하기 위해 아스코르빈산과 NaHCO3을 첨가하여 최적 배합 비율을 선정하여 음료 200 mL당 상황버섯 추출물 55.6 mg (0.0278%), 아스코르빈산 200 mg (0.1%), NaHCO3 60 mg (0.03%)이 함유 되도록 제작하였다. 본 연구 결과 상황버섯추출물은 CPA로 인해 감소된 사이토카인 분비를 상향 조절함으로써 면역저하 상태를 개선시켜 면역 증진 효과가 있는 것으로 판단된다.

Immune activities of two different extracts of Kadsura japonica Dunal. by typical extraction processes using water and ethanol at 60 $^{\circ}$C and 100 $^{\circ}$C were compared to them by ultrasofication system and through traditional fermemtation process. The fermented broth Kadsura japonica Dunal. definitely improved the growth of human B and T cell up to 30% and 22%, respectively, compared to the control. The secretion of TNF-${\alpha}$ and IL-60 was also enhanced by the addition of the fermented broth, up to 35%. NK cell activation was significantly improved up to 1.4 times higher than the case of adding other extracts. It was also found that this broth could yield higher nitric oxide production from macrophage than Lipopolysaccharides (LPS). It can be concluded that Kadsura japonica has immune activities and, in general, the culture broth from a conventional fermentation has higher immune activities, possibly by yielding immuno-modulatory compounds, not existed in typcial extraction systems as the result of HPLC analysis.

We studied the inhibitory effect of solvent fractions from doenjang on mutagenicity using Salmonella typhimurium TA100 in Ames test. We also investigated the effect of solvent fractions from doenjang on the growth of tumor cells and the production of interleukin-2 (IL-2). The treatment of dichlorormethane and ethylacetate fractions (2.5 mg/assay) from doenjang to Ames test system inhibited aflatoxin B$_1$ (AFB$_1$) induced mutagenicity by 96% and 97%, respectively, and showed a higher antimutagenic effect than other solvent fractions. In case of N-methyl-N'-nitro-N-nitrosoguamidine (MNNG) induced mutagenicity, the ethylacetate fraction showed the highest inhibitory effect (by 75%) among the other sol-vent fractions, although the inhibitory effect was not stronger compared to AFB$_1$ induced mutagenicity. The treatment of dichloromethane and ethylacetate fractions markedly inhibited the growth of Yac-1 (by 80% and 94%, respectively) and sacroma-180 cancer cells (by 60% and 96%, respectively) after 4 days of incubation at 37${\circ}$C. To elucidate the immunological mechanism of antitumor activity of doenjang, spleen cells of Balb/c mouse were exposed to the dichloromethane and ethyl-acetate fractions for 24 hours at 37${\circ}$C . The culture supernatants following the treatment of djchloromethane and ethylacetate factions to spleen cells increased the production of IL-2. These results indicated that the anticarcinogenic effect of doenjang was mediated by the production of IL-2.

To confirm therapeutic functionality of Urechis unicinctus which have been favored as a special seafood in Korea, the antitumor and immunological effect of those glycoprotein were studied. 4mg/kg dose of glycoprotein from Urechis unicinctus was most effective in solid tumor growth inhibition (43.63%) of sarcoma 180 cells. However, in case of mice injected with more than dose of 20mg/kg, tumor growth was not inhibited. The higher prolongation ratios were achieved at levels of 2mg/kg with 31.2% and 4mg/kg with 28.9%. The cytotoxic effect of glycoprotein on sarcoma 180 cells was increased slightly as administering level was increased. Number of total peritoneal exudate cells in all the glycoprotein administered groups increased remarkably meaning that Urechis unicinctus gly coprotein could help to improve immunity. Notable body weight change was not resulted in the glycoprotein treated mice compared with control group, but the ratios of both liver or spleen to body weight were increased in mice injected with 20mg/kg and 40mg/kg. These results suggest that the glycoprotein from Urechis unicinctus could stimulate immunity of the mouse bearing tumor cells. Furthermore, the number of leucocytes was also increased by 38.78% at the dose of 20mg/kg and by 46.30% of control at 40mg/kg, while the lower level of 2mg/kg or 4mg/kg showed no effect in increasing leucocyte number. The biochemical values such as GOT and GPT in serum were not changed in mice injected with glycoprotein in comparision with control group.

홍화 (Carthamus tinctorius)는 오래 전부터 각종 감염성 질환이나 암을 치료하는데 효과가 있는 것으로 알려져 왔다. 최근 각종 천연산물에 사람과 동물의 건강을 증진시키는 효과가 있는 것이 밝혀지면서, 홍화의 면역조절 효과에 대한 관심이 높아지고 있으나 이에 대한 과학적 자료가 부족한 실정이다. 따라서, 본 연구는 홍화의 면역 조절 활성을 확인하기 위해 수행되었으며, 면역능 실험을 위해 주로 이용되는 실험용 닭(White Leghorn chickens)에게 홍화잎을 첨가한 실험식이를 3주간 급여한 후 관련 요인들을 분석하였다. 실험 결과, 홍화잎을 섭취한 실험동물에서 비장 면역세포의 증식이 많았고, $Y{\delta}$-TCR+ 세포의 비율이 높아졌으며, 십이지장에서는 IFN-Y, IL-8, IL-10, IL-15 및 NK-lysin 같은 사이토카인의 발현이 높아졌다. 따라서, 홍화잎은 식이와 함께 급여하였을 때 면역 증강 효과가 있는 것으로 밝혀졌으며, 홍화잎을 이용한 각종 제품 개발이 기대된다.
