A 76-year-old man was admitted to our hospital for evaluation of a hepatic tumor. The tumor was described as having hyper-enhancement in the early phase and persistent enhancement in the late phase by contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI), as well as hypervascularity by angiography. CEUS assessment of the nodule showed diffuse and homogeneous enhancement in the pure arterial phase, which became progressively hypoechoic relative to the adjacent liver parenchyma during the portal vein and late phases (mixed vascular phase), and showed a contrast defect with an unclear border in the Kupffer phase. Histologically we diagnosed this hepatic tumor as CoCC. In light of the above findings and the rarity of CoCC, it is helpful to incorporate the results of several imagings, such as CT, MRI, angiography and CEUS with a second-generation contrast agent when clinically diagnosing CoCC.ArticleHEPATOLOGY RESEARCH. 39(2):207-212 (2009)journal articl

Bacteriological investigation of the pollution at Syowa Station in Antarctica
Bacteriological investigation of pollution caused by human being was conducted at Syowa Station. Special attention was paid to the contamination of Enterobacteriaceae (E. coli). The soil, water, air, snow and ice were examined both at Syowa Station and Mizuho Camp. The following results were obtained. E. coli was not detected at the bacteriological pollution monitoring points which were set up by the 15th Japanese Antarctic Research Expedition (JARE-15). On the other hand, in the waterworks and in the drinking water at Syowa Station, E. coli was detected from many parts. But no pathogenic bacteria have been found so far. However, some means of effective prevention should be considered to ensure healthy living at Syowa Station. Some birds were also examined in terms of bacteriological pollution
