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.

Purpose : The purpose of this study was to investigate relationships among family support, self-care, and quality of life of patients with arthritis through a survey. That will be basic data to plan nursing intervention for promoting quality of life for patients with arthritis. Method : The convenient sample of this study consisted of 120 patients with arthritis and data were collected using questionnaires during August 2006 from two OPDs of rheumatoid centers in C University hospitals. The study instruments were used to measure Self Care (So, 1992), Family Support (Kang, 1984), and Quality of Life (Ro, 1988). The data were analyzed using ANOVA, Duncan test, and Pearson correlation. Result : The mean scores were 3.56 for family support, 4.16 for self-care, and 3.19 for quality of life. The level of self-care was significantly higher in those men, having an occupation, higher income, and living with family members. The level of family support was significantly higher in those men, having an occupation, living with family members, and having a helper. The level of quality of life was significantly higher for those men, having a higher income, and shorter length of illness. Three relationships were found to be positively correlated: 1) between the levels of family support and self-care (r=.53), 2) between the levels of self-care and quality of life (r=.55), and 3) between the levels of family support and quality of life (r=.54). Conclusion: Therefore, a nursing intervention program needs to be developed to promote family support, and self-care for quality of life for patients with arthritis.

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.

The purpose of this study is to identificate root canal system including ideal access placement, root curvature. canal configuration, incidence of isthmus in mandibular incisors for success of endodontic treatment. 200 mandibular incisors were selected. The ideal access placement was determimed as follows. The teeth were radiographed from mesiodistal and buccolingual views using intraoral dental film. The image was divided into coronal, middle and apical third using the proximal film. Straight line access was determined by measuring the faciolingual canal width and placing points at midway point between the buccal and lingual wall at the junction of the middle and apical third and at the junction of coronal and middle third of the root canal. A line was drawn connecting these two points extending through the crown of the tooth. The point at which the line crossed the external crown surface was recorded as facial, incisal, lingual. Degree of root curvature was determined by Schneider Protractor Method. Both section method and clearing method were used in this study. By section method, 100 mandibular incisors were embedded in clear resin and transeverse serial sectioned at 0.5, 1.0, 2.0, 3.0, 4.0, 5.0mm level from root apex. The resected surfaces were stained by methylene blue and examined under ×40 marginification with a stereomicroscope. By clearing method, 100 mandibular incisors were cleared in methysalicylate after decalcification with 10% nitric acid and evaluated under ×18 magnification with a stereomicroscope. The results were as follows; 1. 29% had the center of the plotted straight-line access facial to incisal edge, whereas 71% had straight-line access at the incisal edge. When incisal wear classified as extensive, the straight-line access was plotted on the incisal edge 95%. When incisal wear classified as slight/none, the straight-line access was plotted on the facial 65.9%. 2. Degree of curvature of main canal was straight or almost straight, and only 10% in buccolingual direction had a degree of curvature greater than 20 degrees and 5.5% in mesiodistal direction had. 3. In section method, canal configuration analysis showed that 51% of the specimen classified as type Ⅰ, 27% as type Ⅱ, 12% as type Ⅲ, 10$ as type Ⅳ. For thoses sections with two canals, the incidence of an isthmus was 26.7%, 64.3%, 79.2%, 96.3%, 97.4%, 97.6% at each level and highest in 3~5mm sections. 4. In clearing method, canal configuration analysis showed that 74% of the specimen classified as type Ⅰ, 11% as Ⅱ, 6% as type Ⅲ, 9% as type Ⅳ. These results suggested that traditional access from lingual should be moved as far toward the incisal as possible to locate and debride the lingual canal and root canal system should be cleaned. shaped completely and obturated three dimensionally for successful endodontic treatment.

오은경,박형건,배기현,최옥진,최은경,최창근,한진희,정태천 한국환경독성학회 2002 환경독성보건학회지 Vol.17 No.4

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.

본 연구에서는 이취를 유발하는 조류가 정수공정에 유입되었을 경우, 대표적인 고도종수처리 공정으로 알려진 오존처리공정에서 오존접촉시 pH, 총유기탄소(TOC), 자외부 발현성물질(UV-254) 및 NH4+-N 등의 변화특성을 조사하였다. pH가 초기에 7.4에서 오존접촉 10분까지는 급격한 pH 저하현상을 보인 후에 pH는 서서히 감소하는 현상을 보이며 오존접촉 100분에는 2.1까지 저하되었다. TOC와 UV-254는 오존과의 접촉시간에 따라 지속적으로 감소하는 경향을 나타내었다. NH4+-N와 NO2--N의 농도에 비해 NO3--N은 비교할 수 없을 정도의 높은 농도 차이를 보이고 있다. 오존접촉시간이 길어질수록 전기전도도 값도 높아지는 것을 알 수 있었다. The objectives of this research were to estimate variation characteristics of pH. TOC. UV_254 and NH₄^{+}-N. etc. if odorous generated algaes flowed into water treatment plant and they contacted with ozone known as typical advanced treatment. Initial pH 7.4 did suddenly decline to early l0min. and then pH drop did almost occur. and pH decreased to 2.1 in ozone contact 100min.. TOC and UV-254 continued to decrease with passed time of ozone contact. NO₃^{-}-N cocentration was much higher than NH₄^{+}-N and NO₂^{-}-N for whole test period. Conductivity showed high as passed time of ozone contact.
