Hepatocellular carcinoma frequently metastasizes through direct extension, lymphatic, and hematogenous routes. The most common sites of metastasis are the lungs and the lymph nodes, glands, bones, spleen, kidneys, colon, and pleura are the sites of metastasis in decreasing order of frequency. But metastasis to the ovary is very rare. It is thought that metastasize to the ovary occurs through infiltration or dissemination. However, we observed ovarian metastasis of primary hepatic tumor in a 34-year old female who suffered from lower abdominal pain. At first, it was diagnosed as a primary ovarian tumor. But histologically, it presented sinusoidal pattern surrounded by the tumor cells and contained rounded by the tumor cells and contained round hyaline globules in minority of the cytoplasm. Then, the histologic features of percutaneous, sono-guided liver biopsy speecimen of the liver mass are similar to those of resected ovarian tissues. Therefore, we concluded that ovarian tumor was originated from hepatocellular carcinoma. In summary, this report examines a case of hepatocellular carcinoma with ovarian metastasis in a female and reviews the literature.

Park,Yong-Jin,Cho,Gyu-Taek,Ma,Kyung-Ho,Lee,Sok-Young,Lee,Jung-Ro,Kim,Young-Chang,Cho,Eun-Gi,Kim Chang-Yung,Nam,Jung-Hyun,Rao,V,Ramanatha,Kang,Hee-Kyoung 한국자원식물학회 2004 Plant Resources Vol.7 No.2

Genetic background and phylogenetic relationships among 20 Korean wheat cultivars were assessed using microsatellites after amplifying with 13 SSR primer pairs. Average allele number per primer pair was 3.36. Genetic similarities for every pair of cultivars ranged from 0.42 to 0.97, with 0.69 of overall average. Korean cultivars were divided into two major groups based on microsatellite DNA polymorphisms. Group I consisted of relatively old cultivars developed until 1970s, and group II contained the recent cultivars developed during 1980s and 1990s. Amongst old elite cultivars/lines, ‘Yukseung 3’, ‘Norin 12’ and ‘Norin 72’ contributed most to the genetic background of cultivars belonging to group I, and ‘Norin 4’, ‘Norin 12’, ‘Norin 43’ and ‘Norin 72’ to group II, respectively. The phylogenetic relationship of Korean wheat cultivars was in accordance with the genealogical data of each cultivar. The genetic background of each cultivar was assessed from the point of breeding and germplasm management such as variety identification and duplicated accessions for assisting in developing a system for the registration of new variety based on the molecular characterization in future.

목지은,박상진,최기운,최호영 대한치과보존학회 2000 Restorative Dentistry & Endodontics Vol.25 No.4

Urea in the oral cavity is hydrolyzed mainly by bacterial ureases to ammonia, which in turn, raises pH of the oral environment, maintaining oral pH homeostasis, thereby inhibiting dental caries. Streptococcus salivarius has been shown to be a major contribution to oral ureolysis. Synthesis of urease by S. salivarius appears to be constitutive, but can be greatly enhanced in the acidic environment. It has been presumed that ureolytic activity of S. salivarius strains isolated from caries-active site is greater than that of strains from caries-free site. However, no in vivo study has supported the presumption. The present study was performed to observe the ureolytic activity of S. salivarius strains isolated from different environments in the same individual, finding out whether the ureolytic activity is related to dental caries. For the purpose, S. salivarius strains were isolated from caries-active site (>C2), a caries-free site of the tooth, and the dorsum of the tongue of each of 50 patients having decayed teeth. The strains isolated from the patients who harbored S. salivarius in more than two sites were selected and then their ureolytic activities were measured. In order to examine clonal diversity of the strains , their ureC genes were amplified by polymerase chain reaction (PCR) and then restricted with EcoRV, and the protein profiles of the strains were compared by SDS-PAGE. The results were as follows : 1.Of 50 patients, 13 patients harbored S. salivarius in more than two sites; a total of 61 S. salivarius strain were isolated from the patients and selected for the study. 2.Of 17 isolates from the caries-active site of 9 patients harboring S. salivarius in more than two sites including carious lesion, 10 (58.8%) showed a high ureolytic activity (> 200㎛ol/min/mg). While, 19 out of 44 isolates (43.2% ) from the caries-free site of the teeth and the dorsum of the tongues of 13 patients were the strains with a high ureolytic activity. 3.Of 9 patients harboring S. salivarius in more than two sites including caries-active site, 6 patients were found to have the strains in the caries-active site showing a lower ureolytic activity than the strains in the other sites.

Objectives : To clarify clinical features of panic disorder and to compare the characteristics of cognitive patterns, avoidance behaviors, and coping strategies among patients who have panic disorder with or without agoraphobia. Methods : Family backgrounds, cognitive patterns in the first panic attack, coping strategies, and avoidance behaviors were compared among the three groups classified by panic patients with mild agoraphobia(mild PDA=66), severe agoraphobia(severe PDA=71), and without agoraphobia(PD=21) Results : 1) Severe PDA reported significantly high panic attack frequency and more dysfunctional level than PD. 2) Catastrophic thinking of 'dying' in PD was significantly frequent than the other groups. Other fears of 'going craze or loss of control' in severe PDA were the highest among the three groups, though it was not significant. Specific thinking process or interpretation in the first panic attack was not significantly different among the three groups. 3) As avoidance behaviors became worse, the frequency of avoidance behaviors and the patters of avoidance behaviors increased. Conclusions : The results suggested that as avoidance behaviors became worse, the frequency of panic, maladaptive functioning and the patterns of avoidance behaviors increase. This might be why we need to decrease avoidance behaviors through exposure as the treatment.

석회석을 이용하여 혐기성 처리를 위한 폐광산폐수의 화학적 전처리 특성을 평가하였다. 반응시간에 따른 석회석에 의한 처리시 반응종료 2시간에 pH 3.67이였고 SO42-4.7%, Fe 26%, Al 22%, Pb 18% 및 Mn 8%의 제거효율로서 소석회에 비하여 낮은 처리특성을 보여주고 있다. 석회석의 반응속도는 온도가 증가함에 따라 감소하는 경향을 보였다. 혐기성 석회석 충진층의 경우에 실험기간내 pH는 평균 4.51이였고 SO42-4.5%, Fe 15.3%, Al 20.1%, Pb 23.7% 및 Mn 5.87%의 평균 제거효율을 나타내었다. 혐기성 석회석 충진층은 pH 상승효과가 그다지 없었으며 SO42- 및 중금속제거율 또한 아주 낮아 석회석만으로 폐광산폐수의 처리에는 한계점이 있는 것으로 평가되었다. 그러나, 폐광산폐수를 SRB에 의한 처리시의 전처리 공정으로 활용한다면 강산성인 폐광산폐수를 초기에 pH를 상승시켜 처리계에 높은 알칼리도를 제공함으로서 시스템의 안정화에 기여할 수 있을 것으로 여겨진다. This research was carried out to investigate chemical pretreatment using limestone in treat in g abandoned mine drainage with anaerobic treatment. If treating limestone with abandoned mine drainage. after 2day. pH was increased to 3.67, and So₄^{2-}, Fe. Al. Pb and Mn were removed 4.7%. 26%. 22%. 18% and 8%. respectively. It could be showed that limestone did slowly react with temperature increasing. If treating anaerobic limestone packing column with abandoned mine drainage. for experimental period. average pH was 4.51, and average So₄^{2-}, Fe. Al, Pb and Mn were removed 4.5%. 15.3%. 20.1%. 23.7% and 5.87%. respectively. So, it would not be suitable for abandoned mine drainage. But if utilizing limestone as pre- treatment process for treating abandoned mine drainage with SRB, becaus it did initally neutralize abandoned mine drainage, it could forward to stabilize system.

Effects of (±)-camphor on liver cytochrome P450 enzymes were investigated in male ICR mice. Mice were treated intraperitoneally with 0, 200, 400 and 800 mg/kg of (±) -camphor in corn oil for 3 consecutive days. Twenty four hr after the final treatment, the animals were subjected to necropsy. The activities of serum aspartate aminotransferase and serum alanine aminotransferase were slightly changed by the treatment with (±)-camphor at the doses used. Administration o(±)-camphor to mice significantly induced the hepatic activities of pentoxyresorufin O-depentylase and benzyloxyresorufin O-debenzylase and weakly induced ethoxyresorufin O-deethylase in dose-dependent manners. The present results suggested that (±)-camphor might act as a relatively specific inducer of hepatic cytochrome P450 213 in male ICR mice.
