The content of major constituents and antioxidant activities of nine onion cultivars, namely yellow domestic cultivars Meapsihwang, Sinsunhwang, Yeonsinhwang, Yeongbohwang, and Yeongpoonghwang, red domestic cultivar Eumjinara, green domestic cultivar Sweetgreen, yellow-introduced cultivar Sunpower, and red-introduced cultivar Cheonjujeok, were compared. Yeongbohwang and Cheonjujeok had the highest total phenolic and total flavonoid contents among the six yellow and two red cultivars, respectively. The red cultivars displayed the highest DPPH and ABTS⁺ radical scavenging activities (DRSAs and ARSAs, respectively) and reducing power (RP). Among all cultivars, Cheonjujeok and Eumjinara had the highest DRSA, while both red cultivars had similar ARSAs. Among the yellow cultivars, Sinsunhwang and Yeongbohwang showed excellent DRSAs. The RP of the domestic cultivars was slightly higher than that of the introduced cultivars. Thus, the domestic cultivar Yeongbohwang exhibited excellent characteristics among the yellow cultivars, while the red cultivars Eumjinara and Cheonjujeok were similar.

The sulfur amino acid composition in soybean (Glycine max L.) seeds may be an essential characteristic of new cultivars for some animal diets. Variation in seed storage protein among genotypes might make it possible to improve the quality of seed protein by genetically altering seed storage protein composition through plant breeding. This study was carried out to determine if mutant strains have potential for improving seed protein quality in soybean. Ten mutant strains had a distinct characteristic of seed storage protein subunits. Among the mutant strains, the sulfur amino acid compositions(methionine plus cystein) of Keburi(P.I.417016), Keburi(P.I.506817), and P.I.54608-1 were relatively higher than those of the others and were 1.9, 2.1, and 1.8%, repectively, which might be due to low levels of ${\alpha}$, ${\alpha}$', and ${\beta}$ subunits of 7S protein. Therefore, it is concluded that the mutant strains, Keburi(P.I.417016), Keburi(P.I.506817), and P.I.54608-1 appear to be potential materials for a breeding program for improving sulfur amino acid composition, and the others also seem to be possible breeding materials for other uses.

Myxofibrosarcoma is one of the most common soft tissue tumors in elderly patients, mostly arising in the extremities, and rarely arising in the chest wall. A 53-year-old women presented with a painful chest wall mass in the manubrium. We excised the mass. The mass was located subdermally, but had infiltrated the underlying muscle layer, and was histologically diagnosed as an intermediate grade myxofibrosarcoma showing myxoid changes and hypercellularity. Here we report a rare case of chest wall myxofibrosarcoma and present a review of the literature.

Rhabdomyosarcoma is an uncommon type of soft tissue malignant neoplasm characterized by undifferentiated mesodermal tissue. Sarcomas account for approximately 1% of all laryngeal neoplasm and rhabdomyosarcomas are the rarest sarcoma found in the larynx. When the sarcoma involves the larynx, radical surgery such as laryngectomy has been considered. With recent advances of combined therapy, however, it can be treated by conservative surgeries followed by postoperative radiotherapy and/or pulse chemotherapy. With reviews of literature, we report a 47-year-old patient complaining of husky voice and throat discomfort who was finally diagnosed as rhabdomyosarcoma of the vocal fold and successfully treated by laser cordectomy followed by adjuvant chemoradiotherapy.

Pulmonary artery sarcomas are rare, high-grade malignancies, primarily affecting the proximal elastic pulmonary artery and usually manifesting as tumoral impaction on imaging. Due to similar clinical and imaging findings, pulmonary artery sarcomas are frequently misdiagnosed as pulmonary thromboembolism or, occasionally, as vasculitis. Herein, we reported a case of pulmonary artery intimal sarcoma initially misdiagnosed as pulmonary thromboembolism and vasculitis due to its relatively atypical location and morphology, along with a literature review.

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.

Leiomyosarcoma of the inferior vena cava (IVC) is a rare malignant tumor. Yet tumors of a smooth muscle origin are the most common primary neoplasms of the major veins, and the inferior vena cava is the most common site of origin. We report here on a 65-year-old female patient who had been suffering from dyspnea and abdominal discomfort for 3 weeks before admission. The abdominal computed tomography (CT) scan and IVC cavogram showed an IVC mass extending from the right atrium to above the level of the right renal vein, obstructing the IVC, and the radiological findings were suggestive of an IVC leiomyosarcoma. We resected the tumor and reconstructed the IVC with a patch PTFE graft. The follow-up abdominal CT revealed no recurrence and obstruction of the IVC for 6 months after the operation.
