본 연구에서는 국내산 50% 에탄올 복령추출물(KPE)과 중국산 50% 에탄올 복령추출물(CPE)의 약리활성 비교를 위하여 전 지방세포주인 3T3-L1 세포주와 암세포주인 Sarcoma 180 세포주를 이용하여 지방축적 억제활성과 항암활성을 비교하였다. 또한 노지재배 및 시설재배의 1년산 복령과 2년산 복령의 50% 에탄올 복령추출물(LPE, FPE)에 대해서도 50% 항암억제활성($IC_{50}$)로 중국산 복령과 비교하였다. 추가적으로 현재 시중에서 유통되고 CPE와 KPE의 안전성 자료를 획득하고자 단회 경구 독성시험을 실시하였다. CPE와 KPE를 3T3-L1 세포에 처리 후 48시간 이후에 대조군과 비교 시 지방축적 억제를 보였으나(p< 0.05), CPE와 KPE 사이에서는 지방축적 억제활성의 차이가 없었다. Sarcoma 180에 대한 CPE와 KPE의 항암활성을 비교할 때 시험한 농도에서 유사한 활성을 보였지만 $300{\mu}g/mL$의 고농도에서는 KPE가 CPE보다 높은 항암활성을 보였다(p < 0.05). 중국산 복령을 대체하고자 인공재배에서 생산된 노지재배 복령(LPE)과 시설재배 복령(FPE)의 항암활성 비교에서 CPE의 항암활성보다 높게 나타났다(p < 0.05). 단회 독성시험에서 CPE와 KPE의 $LD_{50}$(반수치사량)은 2,000 mg/kg 이상으로 추정되었다. 위의 결과를 종합 시 암세포주인 Sarcoma 180 세포주를 이용한 항암활성측정법은 중국산과 국내산의 원산지 검증의 생물활성검증의 보조수단으로 활용이 가능할 것으로 기대되었다. 국내에서 인공재배 되는 노지재배 복령 및 시설재배 복령은 중국산 복령을 대체하여 수입 감소의 효과를 기대할 수 있으며 지방축적 억제활성 및 항암활성의 기능성 원료로 활용이 가능할 것으로 생각되었다.

The anticancer activities of petroleum ether extract of Panax ginseng root(crude GX) and its partially purified fraction from silicic acid column chromatography (7:3 GX) were studied with Sarcoma 180(S-180) or Walker carcinosarcoma 256 (Walker 256) in vivo and with L1210 leukemic lympocyte in vitro. Potential cytotoxic activities of the crude GX and against L1210 cells were compared with those of 5-Fluorouracil (5-FU) and saponin derivatives (Panax-diol, Panax-triol, Diol saponin, Triol saponin) in vitro. In order to observe the physiological effects of the crude GX and 7:3 GX on the animals with cancer, hemoglobin(Hb), red blood cell(R.B.C) and white blood cell after treatment with each GX in comparison with corresponding control groups, respectively. The anticancer effects of the crude GX and 7:3 GX were estimated by measuring the survival time of S-180 bearing mice after treatment with them. The experimental results obtained are summarized as follows; 1. The one unit of cytotoxic activity against L1210 cells was equivalent to 2.54$\mu\textrm{g}$ and 0.88$\mu\textrm{g}$of the crude GX and 7:3 GX per ml of culture medium, respectively. 2. The cytotoxic activities of Panax-diol, Panax=triol, Diol saponin and triol saponin against L1210 cells were not detected. 3. The anticancer activities of 5-FU against L1210, S-180 and Walker 256 were very effective in vivo and vitro tests. 4. The significantly increased W.B.C values of mice after inoculation with S-180 cells were reduced to normal range by the crude GX treatment. 5. The significantly decreased Hb values of rats after inoculation with Walker 256 were recovered to normal range by oral administration of the crude GX. 6. The survival times of mice inoculated with S-180 cells were extended about 1.5 to 2 times by the 7:3 GX treatment compared with their control group.

Thymic extract showed antitumor effect to sarcoma mice with higher dose$(200{\mu}g/mouse/day$ i.p., 4weeks) but not with low dose$(5{\mu}g/mouse/day$ i.p., 6 weeks). Direct cytotoxicities were exhibited against sarcoma 180, L1210 and MOLT-4 by MTT assay. The spleen weight of mice were increased but the number of circulating lymphocytes were not increased after long-term(2 weeks) administration of thymic extract. Evaluating the mitogenesis by MTT assay. $\%$ absorbance of human lymphocytes was not increased by thymic extract. Cell cycle statistics of S phase and $G_2/M$ phase was not increased in the presence of that by PI staining. The formation of rosette was induced, irrespectively of exposure time short-term(l hour) and long-term(2 weeks). The population of mouse blood T-cell to bind Lyt2-antimonoclonal antibody and to $L_2T_4$ were increased after administration of thymic extract$(2-200{\mu}g/mouse/day)$. From the above results, it is suggested that thymic extract exerts antitumor activity by stimulating T cells to differeniate in vivo but not in vitro.

In the previous study we described the antitumor effect of GLB, a protein-polysaccharide fraction separated from the growing tips of Ganoderma lucidum, against sarcoma 18 0 solid tumor in ICR mice. In this study, we separated an acidic protein-polysaccharide fraction, GLB-A, and a basic protein-polyaccharide fraction, GLB-B, from GLB by differential precipitation, and elucidated their antitumor and immunomodulatory activities. When ip injected at the dose of 50mg/kg/day into the ICR mice, GLB-A and GLB-B inhibited the growth of ip implantated sarcoma 180 cells by 32.4% and 21.0%, respectively. Of these, GLB-A increased the % lymphoblast in the spleen of the tumor-bearing and the normal mice by 20.9% and 123.0%, and the CD4/CD8 ratio by 73.3% and 22.4%, respectively. GLB-A also increased the expression of CD25 (IL-2 receptor alpha ch0ain) in normal mice by 82.0%. These results strongly suggest that GLB-A is a promising candidate for antitumor immunomodulatory medicine.

목적 : bFGF (basic fibroblast growth factor)는 섬유아세포(fibroblast)에서 분비하는 대표적인 성장인자로 섬유아세포뿐 아니라 간질조직과 골수 및 다른 상피 근원세포의 성장에도 관여하며 방사선보호제 역할에 관한 연구가 시도되고 있다. 이 연구는 방사선보호제로서의 bFGF의 기능을 알아보고자 하였다. 대상 및 방법 : 간엽조직 기원(mesenchymal origin)인 마우스육종 180 종양세포를 생쥐 대퇴부 피하에 이식하고 bFGF를 투여한 후 전신방사선조사(6, 8, 10 Gy)하여 생쥐의 생존률을 조사하고 bFGF (3, $6\;{\mu}g$/쥐)의 방사선보호효과를 관찰하였다. 동시에 이식한 마우스 180 고형종양을 국소방사선조사한 후 bFGF가 종양성장에 미치는 영향을 알아보았다. 또한 bFGF에 의한 방사선보호효과의 기전을 이해 하고자 소장점막, 골수, 폐조직 및 이식종양조직에 대한 병리 조직학적 검사와 DNA terminal transferase nick-end labeling assay 방법으로 아포프토시스(apoptosis) 빈도를 측정하였다. 결과 : 1) 방사선조사단독군에 비해 방사선조사와 $6\;{\mu}g$ bFGF 투여병행군에서 생쥐의 골수치사를 감소시켜 생존률이 증가되었다(p<0.05). 2) 방사선조사단독군에 비해 방사선조사와 $6\;{\mu}g$ bFGF 투여병행군에서 공장 소낭선 깊이 및 미세융모 길이가 의의 있게 증가되었다(p<0.05). 소낭선세포의 아포프토시스 빈도는 방사선조사단독군에 비해 방사선조사와 bFGF 투여병행군에서 방사선조사후 8시간, 24시간에 감소하였으며 bFGF를 고용량 투여한 군에서 뚜렷하였다. 3) 골수조직에서는 방사선조사 후 7일, 14일째 세포 밀도가 방사선조사단독군에 비해 방사선조사와 $6\;{\mu}g$ bFGF 투여병행군에서 증가하였으며 특히 거핵구(megakaryocyte) 계열의 증가가 뚜렷하였다. 4) 폐조직의 H-E 염색 조직소견에서 방사선단독군과 방사선조사와 bFGF 투여병행군 간의 차이는 없었다. 5) 골수 및 폐 조직에서 bFGF 투여에 따른 초기 아포프토시스 빈도의 차이는 려었다(p>0.05). 6) 양성대조군과 bFGF단독투여군 비교시 bFGF투여에 의한 종양성장은 관찰되지 않았으며(p>0.05) 방사선조사단독군과 방사선조사와 $6\;{\mu}g$ bFGF 투여병행군에서도 종양성장곡선의 차이는 없었다(p>0.05). 결론 : 이상의 결과로 bFGF는 소장점막 및 골수세포에 방사선보호효과가 있었으며 그 기전은 조혈모세포 및 소장낭선세포의 성장 및 재생을 촉진하고 조기에 방사선으로 유도된 아포프토시스를 감소시키기 때문인 것으로 생각된다.

Augmentation of antitumor activity of antitumor drugs in combination with Lactobacillus casei HY2782 (LC2782) was studied against Sarcoma-180 (S-180) and Lewis lung carcinoma (3LL). Antitumor drugs used in this study were 5-fluorouracil (5-fu) and cyclophosphamide (CP). The prolongation effect of LC2872 on the life span of mouse intraperitoneally implanted with S-180 was stronger than that of OK-432 and BCG, while the inhibitory effect of OK-432 and BCG on the growth of 3LL solid tumor was a little stronger than that of LC2782. Average survival rates of mice administrated LC2782, OK-432 and BCG were 192%, 141%, and 112%, respectively, when that of the control was 100%, Intralesional administration of 5-Fu, CP, 5-Fu+LC2782 and CP+LC2782 resulted in 93%, 69%, 99% and 73% inhibition rates against 3LL solid tumor proliferation. The combination therapy of 5-Fu or CP with LC2782 significantly prolonged the life span of S-180-inoculated ICR mice. Average survival rates of mice administrated 5-Fu and CP alone were 115% and 99%. Furthermore, survival rates of mice administrated 5-Fu and CP in combination with LC2782 were 226% and 244%, respectively.
