  • Villoglandular adenocarcinoma of uterine cervix has recently been described, and is characterized by good prognosis and occurrence in young women, except a small number of cases. Morphologically, it exclusively shows villoglandular growth and mild to moderate nuclear atypia, the cytologic diagnoses have been frequently missed due to interpretation error. We report here on the cytologic findings of two cases, and both cases were not diagnosed as adenocarcinoma before punch biopsy. One of these cases showed previously described characteristic features such as high cellularity and large tissue fragments with long villous fronds lined by columnar cell with mild nuclear atypia. The other showed moderate cellularity of somewhat smaller clusters without long villous structures. The clusters showed marked nuclear overlapping and the nuclei showed distinct moderate atypia with hyperchromasia and coarse chromatin pattern. The nucleoli were indistinct. Recognition of these features will be helpful to avoid underdiagnosis as a benign lesion, although diagnosis is still difficult in a portion of the cases.

  • 단어 의미 유사도 측정은 정보 검색이나 문서 분류와 같이 자연어 처리 분야 문제를 해결하는 데 큰 도움을 준다. 이러한 의미 유사도 측정 문제를 해결하기 위하여 단어의 계층 구조를 사용한 기존 연구들이 있지만 이는 단어의 의미를 고려하고 있지 않아 만족스럽지 못한 결과를 보여주고 있다. 본 논문에서는 국립국어원에서 간행한 표준국어대사전에 50만 어휘가 추가된 우리말샘 사전을 기반으로 하여 한국어 단어에 대한 계층 구조를 파악했다. 그리고 단어의 용례를 word2vec 모델에 학습하여 단어의 문맥적 의미를 파악하고, 단어의 정의문을 sent2vec 모델에 학습하여 단어의 사전적 의미를 파악했다. 또한, 구축된 계층 구조와 학습된 word2vec, sent2vec 모델을 이용하여 한국어 단어 의미 유사도를 측정하는 모델을 제안했다. 마지막으로 성능 평가를 통해 제안하는 모델이 기존 모델보다 향상된 성능을 보임을 입증했다.

  • The purpose of this study was to investigate the influence of metabolic syndrome (MS) on the lower urinary tract symptoms (LUTS), prostate specific antigen (PSA), and prostate volume in Korean men. We analyzed the data from 2654 men over the age of 40 who visited our health promotion center for regular health checkups. Of the total 2654 men, mean age, PSA level, International Prostate Symptom Score (IPSS), and prostate volume were 54.6 years, 1.21ng/ml, 6.2 points, and 27.8ml, respectively. All examinees were divided into MS group (46.5%, 1235 men) and non-MS group (53.5%, 1419). Age and prostate volume were significantly higher in the MS group. The patients were divided into three groups according to their ages: 40's, 50's, and over 60 years old. Prostate volume of the MS group in the younger age groups (40-49 years and 50-59 years) was significantly larger than that of the non-MS group. However, no difference was revealed in the age group of 60-69 years. No significant differences were found in the PSA level and LUTS between the MS and non-MS groups. In the multivariate regression analysis, central obesity was the strongest risk factor for the enlargement of prostate over 30ml among the metabolic components.

  • An adenomyoma of the gastrointestinal tract is a rare, benign, tumor-like condition histologically characterized by glandular structures embedded within a smooth muscle stroma. An adenomyoma has been considered to be as an abortive variant of an ectopic pancreas. An ectopic pancreas is defined as the presence of pancreatic tissue that lacks anatomic and vascular continuity with the main body of the pancreas. Common sites of an ectopic pancreas are the stomach, duodenum, and upper jejunum. An adenomyoma may rarely undergo a malignant transformation or cystic dystrophy. Recently, the authors an experienced a case of an incidental adenomyoma of the stomach associated with early gastric carcinoma. We report that case here.

  • A 10-year-old intact female Yorkshire terrier dog was referred for evaluation of marked abdominal distension and hemorrhagic effusion. Abdominal radiography and ultrasonography demonstrated abdominal effusion and intraabdominal mass with anechoic cystic components. On ascites cytology, neoplastic epithelial cells with vacuolated cytoplasm and prominent nucleoli were identified. Magnetic resonance imaging (MRI) showed the well-defined, heterogeneous, and large mass filled the intraabdominal cavity. At necropsy, a large mass arising from the right ovary was observed. Histopathologically, the mass was composed of papillary structures lined by neoplastic epithelial cells. The dog was definitively diagnosed as malignant ovarian adenocarcinoma with papillary pattern based on clinical and histopathological findings.

  • This study was carried out examine the effect of Celeriac Extract, which contains various anticancer ingredients, on the proliferation inhibition of human-derived cancer cells and the degree of inhibition. The five cell lines used in the experiment were lung cancer cells A549, prostate cancer cells DU-145, uterine cancer cells HeLa, breast cancer cells MCF-7, and liver cancer cells SNU-182. All cancer cells derived from the human body were used, and the inhibition of cancer cell proliferation with Celeriac Extract 10ug/mL, 100ug/mL, and 1000ug/mL was measured using the CCK-8 method. As a result of examining the inhibition of cancer cell proliferation, Celeriac Extract 1000ug/mL showed significant proliferation inhibition in lung cancer cells A549, prostate cancer cells DU-145, uterine cancer cells HeLa, and liver cancer cells SNU-182, and showed a concentration dependence. However, only a concentration-dependent decrease was observed in breast cancer cells MCF-7.In conclusion, it can be seen that the cell proliferation inhibition mechanisms of Celeriac Extract using various human-derived cancer cell lines provide the potential for cancer prevention and therapeutic development.
