  • This study investigated the anti-cancer effects of Salicornia herbacea L. fractions in human ovarian cancer cells (OVCAR-3). S. herbacea powder was extracted with 95% EtOH and sequentially fractionated with hexane, dichloromethane (DCM), ethyl acetate, butanol, and H2O. Further, the growth inhibitory effects of the six fractions were determined using the MTS assay. The DCM fraction dramatically decreased cell viability. Similarly, the cell cycle was arrested at the subG1 phase in DCM-treated cells. To confirm apoptosis, the cells were stained with annexin V/FITC-PI solution. Total, early, and late apoptotic cells were significantly increased in the DCM fraction. The mRNA expression of Bcl-2 was reduced, whereas the pro-apoptotic factors Bax and Bak were increased in DCM fraction-treated cells. These results indicated that the DCM fraction in S. herbacea exhibited strong apoptotic effects through the p53-dependent signaling pathway.

  • The early gonadal development and sex differentiation of the mandarin fish, Siniperca scherzeri was described from hatch to the 130th day post-hatch (DPH). Primordial germ cells were observed on the just hatched fry (5.10 mm in total length (TL)) and began to protrude into the peritoneal cavity between mesonephric duct and gut. The primordial gonad, with the formation of genital ridge, developed on the 8-10th DPH (10.77-12.47 mm TL). Ovarian differentiation was identified by the presence of ovarian cavity and meiotic oocytes from the 40th DPH (29.75 mm TL). Testicular differentiation was identified by the presence of spermatogonial cells with efferent duct also from the 40th DPH. Sex differentiation of the mandarin fish was identified as gonochoristic type.

  • The root of Adenophora triphylla is a highly valued medicinal resource that is used to prevent human obesity, cancer, and inflammation, whereas young leaves or sprouts of A. triphylla are used as food ingredients. In this study, we compared the antioxidant and anticancer activities of 70% ethanol extracts of A. triphylla roots and leaves. The leaf extract exhibited stronger 2,2-diphenyl-1-picrylhydrazyl (DPPH)-radical scavenging activity, reducing power, and oxygen radical absorbance capacity (ORAC) than the root extract. Furthermore, the leaf extract was observed to be a potent source of anticancer compounds that were effective against A549 (lung cancer), LNcaP (prostate cancer), SKOV3 (ovarian cancer), and Caco-2 (colorectal cancer) cells. These results indicate that not only the roots but also the leaves of A. triphylla can serve as valuable sources of functional materials in the pharmaceutical industry.

  • Circulating tumor cells (CTCs) in the bloodstream of cancer patients provide an accessible source for detection, characterization, and monitoring of nonhematological cancers. The effectiveness of the CTC-Chip for the isolation of ovarian cancer cells was demonstrated by adapting the herringbone-chip (HB-Chip). The motions of the particles on the HB chip were simulated by a unique combination of buoyant, gravitational forces, and helical flows with a computational modeling. The motions of cells are demonstrated by applying polystylene bead and ovarian cancer cells into the microfabricated HB-Chip. The experimental results from beads and cells are well accordance with the simulated ones, as previously reported by Toner group. Thus, I expect that these modeling and experimental skills will play key roles in the clinical applications on CTC isolation as well as the basic research on characterization of CTCs under flow.

  • Various lines of evidence suggest that dietary components protect the initiation of carcinogenesis. In this study, the ethanol extracts (AGE) and the methanol and hexane partition layers (AGEM, AGEH) of the Angelica radix were screened for their cytotoxic effects using the MTT assay on HepG2, HeLa, MCF7 and SW626 cells and for their ability to induce quinone reductase (QR) in HepG2 cells. AGEM and AGEH of the Angelica radix showed the strongest cytotoxic effects on HepG2 and HeLa cells. Cell growth was inhibited by 99.8% and 99.8% on HepG2 cells and 99.3% and 99.4% on HeLa cells, at dose of $100\;\mu\textrm{g}/ml$ of AGEM and AGEH extracts respectively. AGE and AGEH significantly induced QR activities in the HepG2 cells. The QR activities of HepG2 cells grown in the presence of AGE, AGEH, and AGEM at the concentration of $50\;\mu\textrm{g}/mL$ were 313.5, 273.3 and 133.3 nmol/min/mg protein, respectively. Therefore, based on these studies, Angelica radix may be developed into a potentially useful cancer chemopreventive agent.

  • 목 적: 본 연구의 목적은 유방암 세포(MCF-7) 이식 누드 마우스 모델을 이용하여 육종용 열수 추출물의 면역활성 효과를 통한 항암 활성을 체계적으로 평가하는 것이다. 육종용 열수 추출물은 유방암 치료제로 자주 사용되는 대표적인 경구용 항암제인 tamoxifen 경구 투여군과 비교하여 분석 연구하였다. 방 법: 총 110마리의 6주령 암컷 누드 마우스를 준비하여, 7일간 적응 후 체중이 일정한 마우스를 선정하여 우측 둔부 피하부위에 MCF-7 세포를 이식하였다. 종양세포 이식을 한 지 20일 후, 종양 크기 및 체중을 기준으로 그룹 당 8마리씩 본 실험에 사용하였다. MCF-7 이종 이식 21일 후부터 매일 1회씩 35일간 육종용 열수 추출물을 10 ml/kg의 용량(400, 200 및 100 mg/kg)으로 경구 투여하였으며, tamoxifen 역시 10 ml/kg의 용량(20 mg/kg)으로 경구 투여하였고, 정상 및 종양 이식 매체 대조군에서는 멸균증류수만 종양 이식 21일 후부터 동일한 방법으로 35일간 경구 투여 하였다. 결 과: 본 실험의 결과, MCF-7 세포 이식을 함으로써 현저한 비장 및 하악하 림프절 무게, 혈중 IFN-γ의 함량, IL-1β 및 IL-10의 함량, 비장내 TNF-α, 비장세포 및 복강 대식구의 활성의 감소가 관찰되었고, 비장 및 하악하 림프절의 림프구 감소에 의한 조직병리학적 위축 또한 관찰되었다. 그리고 체중 및 증체량의 감소 역시 관찰되었으며, 혈중 IL-6 함량의 증가, 난소 주위의 지방 무게의 감소 및 조직병리학적으로 난소 주위의 축적 지방 조직 위축 현상이 인정되어, 종양 이식 후에 전형적인 종양과 관련된 면역억제와 악액질 현상이 유발된 것으로 판단되었다. 한편 육종용 열수 추출물 400, 200 및 100 mg/kg 경구 투여군에서는 종양 이식 대조군에 비해 유의성 있는 현저한 항암활성이 투여 용량 의존적으로 관찰되었다. 또한 tamoxifen 20 mg/kg 경구 투여군에서는 종양 관련 악액질 소견이 오히려 악화되는 반면, 육종용 열수 추출물 경구 투여군에서는 면역활성 및 악액질 억제 효과가 관찰되었다. 결 론: 본 연구 결과, 육종용 열수 추출물의 적절한 경구 투여는 심각한 부작용 없이, 종양 관련 악액질 소견을 포함하여, 효과적인 유방암 치료 수단을 제공할 수 있을 것으로 기대된다.

  • In this study, we investigated the preventive and therapeutic effects of antler-extract for osteoporosis. Rats were ovariectomized bilaterally and were fed up with Ca- and P-free diet in order to induce osteoporosis. Body weight, organ weight, the weight of femur and bone ash quantity were examined for 5 weeks. We also performed histological and electronical microscopic examinations. 1. After adminstration of female and male antler extract to osteoporosis-induced rats at the doses of 625 and 1250 mg/kg, respectively, the body weights were significantly increased compared with those of normal control group's which was 230.2:t2.3-281.0:t2.5g (p<0.05). 2. The weights of both right and left femur of osteoporosis-induced rats, administered with female or male antler-extract, little decreased compared with those of normal control group. 3. The bone ash quanties of femur of osteoporosis-induced rats, administered with female or male antler-extract, little decreased compared with those of normal control group. 4. The weights of liver, spleen, and kidney of osteoporosis-induced rats, administered with female or male antler-extract, decreased compared with those of normal control group. 5. Histological and electronic microscopical findings were (1) that in normal control rats the connectional of lacunae appeared well and were without loss of bone mineral, (2) that in ovariectomized rats the connections of lacunae were mostly broken and were with loss of bone mineral compared with those of normal control rats, (3) that in osteoporosis-induced rats, administrated with female or male antler-extract, the shape of lacunae and the connections of them were similar to those of normal control rats. These findings suggest a possible protective and therapeutic effects of female or male antler extract against bone loss in ovariectomized rats.

  • A 4-year-old female Shih-tzu dog weighing 5.1 kg was referred with abdominal distension and diagnosed as cystic papillary adenocarcinoma with metastasis to serosal surface of abdomen by biopsy. Intraperitoneal chemotherapy with cisplatin (50 $mg/m^2$) diluted in normal saline (250 $ml/m^2$) was initiated following removal of ascites one month after ovariohysterectomy (OHE). Clinical response was great and had no side effects during the chemotherapy period (3 relapses, 33 months after diagnosis). However, pleural effusion occurred with ascites and renal failure at the end of treatment. Eleven treatments of cisplatin were performed during 35 months after diagnosis. Intraperitoneal cisplatin instillation has been effective to control malignant ascites and pleural effusion in ovarian cancers and could be a reasonable palliative treatment. This is the first case report describing intraperitoneal cisplatin chemotherapy in metastatic ovarian cyst papillary adenocarcinoma in Korea.
