The study was carried out to measure the antitumor effect of traditional doenjang (Korean soybean paste) added with Japanese apricot, garlic or ginger. Four kinds of traditional doenjang inhibited significantly the tumor growth in mice injected sarcoma-I80 cells. Especially, traditional doenjang added with ginger (Gi-TD) showed an inhibition of tumor cell activity of 97% by the administration of 1.0 mg/kg methanol extracts. Among Balb/c mouse administered doenjang extracts, the liver weight of mice fed Gi-TD was heavier than that of the group not administered doenjang. However, no difference was found between the control and doenjang administrated groups in weights of body, spleen, kidney and heart. The activity of natural killer (NK) cells was relatively high in mice administrated with the four kinds of doenjang. Particularly, mice administrated with the Gi-TD methanol extracts showed a strong activity of 82.9%. The activity of glutathione S-transferase (GST) in mice administrated with the 4 kinds of doenjang was higher than that of the group not administered with doenjang. In particular, the GST activity was the strongest in the group administrated with Gi-TD. The results suggest that Gi-TD has a strong growth inhibition activity against sarcoma-180 tumor cells.

최근 많은 관심을 가지는 유산균은 사람이나 동물의 장내 방어 장벽인 위산, 담즙산염, 췌장에 효과가 있고, 이들 생균은 장 점막에 쉽게 집락화하는 특성을 가지면서도 인체에는 무해한 균이기 때문에 식품첨가물 부분에서 GRAS(Generally Recognized As Safe)로 분류되어 있고, 이런 안전성을 기반으로 수많은 제품이 제조되어 유통되고 있다. 유산균의 다양한 연구는 유산균 생균제, 사균체, 유산균 파쇄액을 이용하여 항암 효과, 유당 단백질의 흡수 증진, 콜레스테롤의 저하 류머티스 관절염 치료 및 정장작용 개선에 효과적인 기능을 가진다고 보고하고 있다. 이런 다양한 효과를 가지는 유산균의 기능을 이용하기 위하여 금번 연구에서는 항암 활성이 우수한 Lactobacillus casei의 2차 산물인 배양여액에서 순수 분리한 것으로 UItrafiltration membrane(3, 30 KDa)으로 분리 농축한 단백질 물질인 CBT-AK5을 실험에 사용하였다. 이전 연구로 CBT-AK5가 정상세포와 암세포주를 이용한 세포 독성 실험 및 암세포 생육 억제 활성을 측정한 결과, 정상세포에 대한 세포 독성은 20% 이내로 낮은 세포 독성 효과를 나타난 반면, 각 장기별 암세포주에 대한 암세포 생육 억제 활성을 측정한 결과 70% 이상의 높은 암세포 생육 억제 활성을 나타내어 항암 활성 물질임을 확인하였다. Lactobacillus casei의 2차 산물인 배양여액에서 순수 분리한 CBT-AK5의 항암 효과에 대한 in vivo 실험을 실시하였다. In vivo 실험으로 6~8주령된 ICR mice를 사용하였고, 복수암 유발 및 고형암 유발을 위해 Sarcoma-180 cell line이용하였다. 투여 방법으로는 경구투여와 복강내 투여로 나누어 진행하였고, 각 투여 방법에 따른 치료군과 예방군으로 나누어 실험하였다. 또한 치료군과 예방군마다 다른 농도별($25\;{\mu}g/m{\ell}$, $250\;{\mu}g/m{\ell}$, $2.5\;{\mu}g/m{\ell}$ 차이도 관찰하였다. 위 실험에서 경구투여에 따른 항암 활성 효과는 양성대조군보다 체중 증가와 생존율 비교에 있어서 정상군보다 다소 높게 관찰되었으나, In vitro 실험시 높은 항암 활성 효과에 비해 유의적이지 않았다. 하지만, 복강내 투여에 따른 항암 활성 효과는 양성대조군보다 체중 증가와 생존율 비교에 있어서 높은 활성 효과가 관찰되었고, 치료군과 예방군 모두에서 항암 활성이 우수한 물질임을 확인하였다. 이상의 실험에서 Lactobacillus casei의 2차 산물인 배양여액에서 순수 분리한 CBT-AK5가 항암 활성에 우수한 물질임을 확인하였다.

저령의 균핵으로부터 중성염용액, 열수 및 메탄올 추출물을 분리하였다. 세포독성 실험 결과, 중성염용액 추출물은 $0{\sim}2,000\;{\mu}g/ml$의 농도에서 NIH3T3, Sarcoma 180 및 MCF-7에 대한 세포독성이 없었으나, 메탄올 추출물에서는 $1,000\;{\mu}g/ml$ 이상의 농도에서는 독성을 나타내었다. Sarcoma 180 복수암에 대한 항암 효과는 중성염용액 추출물을 투여한 실험군에서 66.74%의 높은 생명 연장 효과를 나타내었으며, 암세포의 생 세포 수 또한 54.2% 감소시키는 효과를 나타내었다. 중성염용액 추출물은 대조군에 비해 보체 대체 경로에서의 항보체 활성을 $85.05{\sim}88.73%$, B 임파구의 alkaline phosphatase 활성을 6배 이상 증가시킴으로써 면역 활성 효과를 향상시켰다. 또한 중성염용액 추출물을 50 mg/kg body weight의 농도로 마우스 복강에 투여하였을 때 대조군에 비하여 복강세포수가 1.7배 증가하였으며, 혈액 내 백혈구 수 또한 3.6배의 증가를 나타내었다. 간, 비장 및 흉선 등의 면역 관련 장기의 체중에 대한 중량을 측정한 결과, 중성염용액 추출물 투여군은 대조군에 비해 증가된 수치를 보였으며, 혈액생화학적 검사를 시행한 결과, 대조군과 유사한 경향을 나타내었다. 중성염용액 추출물의 총 다당류와 단백질의 함양은 각각 98.25%와 1.44%로 측정되었다. 따라서 저령균핵의 중성염용액 추출물의 항암 효과가 암세포에 대한 직접적인 세포독성에 의한 것이 아니고 면역활성에 의한 것으로 판단된다.

This study was undertaken to evaluate the antitumor activities of Cordyceps militaris of silkworm pupa (CMP) and silkworm larva (CML), as compared with the effect of cordycepin, an active compound found in Cordyceps militaris. Antiproliferation effect of the test materials were evaluated in the sarcoma-180 cells using the MTT test. For the in vivo study, ICR mice were inoculated i.p. with 1.0 ${\times}$ 10$^{6}$ sarcoma-180 cells/mouse on Day 0, and were again i.p. injected with one of the following substances from Day 1 to Day 10 : saline (control group), 50 mg/kg (CMP50, CML50) ,100 ma/kg (CMP100, CML100), or 200 mg/kg (CMP200, CML200) of Cordyceps militaris water extracts, or 1 mg/kg (C1), 2 mg/kg (C2), or 4 mg/kg (C4) of cordycepin. Pretreatment of the sarcoma-180 cells with 100 mg/ml, 500 mg/ml, and 1000 mg/ml of CML (60.1$\pm$2.5％, 49.8$\pm$3.7％, and 45.4$\pm$0.1％ of the value for untreated control cells, respectively) or CMP (68.3$\pm$2.1％, 55.1$\pm$0.9％, and 51.4$\pm$3.5％ of the value for control cells, respectively) for 48 hrs significantly decreased the survival rate (proliferation) of tumor cells (p<0.05). Body weight of the control mice bearing ascites tumor and injected with saline was 1.4 times of the value for normal animals at day 18. Mice bearing ascites tumor and injected with cordycepin (1, 2, or 4 mg/kg) exhibited a significantly lighter body weight compared with the control mice, while animals injected with CMP or CML (50, 100, or 200 mg/kg) showed a significantly lighter body weight compared with the mice injected with cordycepin. Mice injected with CMP50, CMP100, or CMP200 mg/kg (or CML50, CML100, or CML200 mg/kg) showed a 133％ (or 90％), 80％ (or 62％), and 68％ (or 52％) longer mean survival time, and those treated with C1, C2, or C4 exhibited a 54％, 91％ and 80％ longer survival time compared to the value for control mice injected with saline. These results indicate that the hot-water extracts of Cordyceps militaris of both silkworm pupa and silkworm larva have an anti-proliferation effect of tumor cells as well as the life prolongation effect in mice bearing ascites tumor, which are superior to the activities of cordycepin.

Background: Realgar which contains arsenic components has been used in traditional Chinese medicine (TCM) as an anticancer drug. However, neither Realgar nor its formula are soluble in water. As a result, high dose of Realgar has to be administered to achieve an effective blood medicine concentration, and this is associated with adverse side effects. The objective of the present study was to increase the solubility of a formula using hydrometallurgy technology as well as investigating its effects on in vitro and in vivo cell proliferation and apoptosis in Sarcoma-180 cell line. Materials and Methods: Antiproliferative activity of Realgar Bioleaching Solution (RBS) was evaluated by MTT assay. Further, effects of RBS on cell proliferation and apoptosis were studied using flow cytometry and transmission electron microscopy. Kunming mice were administered RBS in vivo, where arsenic specifically targeted solid tumors. Results: The results indicated that RBS extract potently inhibited the tumor growth of Sarcoma-180 cell line in a dose-dependent manner. Flow cytometry and transmission electron microscopy further indicated that RBS significantly induced cell apoptosis through the inhibition of cell cycle pathway in a dose-dependent manner. Further, on RBS administration to mice, arsenic was specifically targeted to solid tumor.s Conclusions: RBS could substitute for traditional Realgar or its formula to work as a potent tool in cancer treatment.

A mutant herpes simplex virus 1, mtHSV, was constructed by inserting the E. coli beta-galactosidase gene into the loci of icp34.5, the apoptosis-inhibiting gene of HSV. The mtHSV replicated in and lysed U251 (human glioma cells), EJ (human bladder cells), and S-180 (mice sarcoma cells), but not Wish (human amnion cells) cells. With its intact tk (thymidine kinase) gene, mtHSV exhibited susceptibility to acyclovir (ACV), which provided an approach to control viral replication. An in vivo test with mtHSV was conducted in immune-competent mice bearing sarcoma S-180 tumors, which were treated with a single intratumoral injection of mtHSV or PBS. Tumor dimensions then were measured at serial time points, and the tumor volumes were calculated. Sarcoma growth was significantly inhibited with prolonged time and reduced tumor volume. There was microscopic evidence of necrosis of tumors in treated mice, whereas no damage was found in other organs. Immunohistochemical staining revealed that virus replication was exclusively confined to the treated tumor cells. HSV-1 DNA was detected in tumors, but not in the other organs by a polymerase chain reaction analysis. From these experiments, we concluded that mtHSV should be a safe and promising oncolytic agent for cancer treatment.
