The purpose of this study is to work out strategy for utilization of Environmental Conservation Value Assessment Map (ECVAM) using the user survey. It surveyed system users of ECVAM about its recognition and satisfaction. The results of the survey, the ECVAM became more popular and were highly satisfied with updated data. Especially, the study found a relationship between the satisfaction of ECVAM and accuracy, utilization, and convenience of the system. However, the satisfaction has a difference between user groups, a government official and a agent for EIA including researchers. The satisfaction of the agent group was affected by the convenience, the accuracy, and the utilization in order. In the other hand, the satisfaction of the government official group was affected by the utilization, the convenience, the accuracy, and recognition in order. Therefore, we need to adopt different strategies for educations of ECVAM and publicity activities depending on user groups. To increase t...

Autoimmune pancreatitis (AIP) is a benign disorder and a unique form of chronic pancreatitis with several characteristic features. A cystic formation that mimics a pseudocyst is a rare finding. There have been a few reports of AIP complicated by pancreatic cysts. We present a case of AIP with multiple pseudocysts and obstructive jaundice caused by IgG4-associated cholangitis. We initially missed the diagnosis due to the pseudocyst. Based on the computed tomography images, laboratory findings and the therapeutic response to steroids, the case was diagnosed as AIP with pseudocysts and associated cholangiopathy.

Primary pancreatic lymphoma is rare, comprising 0.2-4.9% of all pancreatic malignancies and less than 1% of cases of non-Hodgkin's lymphoma. Many patients are diagnosed with lymphoma after radical resection. We report a rare presentation of diffuse large B cell lymphoma, appearing as a primary tumor of the pancreas. A 61-year old female was admitted to the hospital with the complaint of right upper abdominal pain. Computed tomography of the abdomen showed a well defined mass located at the head of the pancreas. A frozen section of pancreas, during laparotomy, revealed lymphoma. The patient received 6 cycles of chemotherapy and is currently in complete remission. This case underscores the importance of differentiating primary lymphoma from the more common adenocarcinoma of the pancreas as treatment and prognosis differ significantly. Primary pancreatic lymphoma should be considered in the differential diagnosis of pancreatic tumors and an attempt to obtain a tissue diagnosis is a...

The prognosis of advanced hepatocellular carcinoma (HCC) tends to be poor. Spontaneous regression of this lesion is extremely rare. In this report, we describe a case of HCC which spontaneously regressed along with a metastatic lesion of the chest wall. A huge HCC in the right lobe, the largest diameter of which was about 15 x 12 cm, developed in a 72-year-old man. He and his family refused further treatment. Three months after the diagnosis, metastasis to the chest wall was detected. We prescribed a painkiller for him in order to alleviate chest pain. Fourteen months after the diagnosis, the tumor size of the primary lesion was downsized to 3 x 4 cm in diameter. A biopsy taken from the chest wall proved to be clear cell HCC (CHCC). Since then, the metastatic lesion has also disappeared. Here, we report this unusual histologically proven CHCC with literature reviews.

The Baekdudaegan Mountain Range is a backbone of the Korean Peninsula which has special spiritual and sentimental significance for Koreans and significant ecological value to diverse organisms. Despite the importance of this region, however, the natural environment of Baekdudaegan has been severely threatened by a variety of human activity and tremendous forest fires. To make management and restoration plans for

Pseudomembranous colitis (PMC) is known to develop after antibiotic administration, but antituberculosis agents are rarely associated with this disorder. We report 6 cases of PMC after rifampicin administration; the clinical manifestations, laboratory findings, imaging findings, and clinical course are described. The median age of patients was 68 years (range, 54 to 82 y). All patients were diagnosed with active pulmonary tuberculosis by sputum smear and culture, and 2 suffered from type 2 diabetes mellitus. The average interval between initiation of antituberculosis therapy and the onset of diarrhea was 19.8 days. The anatomic distribution of PMC included the rectum and sigmoid colon in 5 cases and up to the hepatic flexure in 1 case. All patients were cured with medical treatment, which include discontinuation of rifampicin and oral metronidazole and vancomycin. PMC recurred in 1 patient after retreatment with rifampicin. Our findings suggest that patients who are treated with antituberculosis agents, who develop acute diarrhea during or after therapy, should be evaluated for PMC.
