본 조사는 내장산 국립공원내 굴거리나무 군락지를 대상으로 시설양묘를 위한 기초자료를 구명하고자 광환경이 다른 조건에서 자라고 있는 치수의 생장특성을 조사하였다. 굴거리나무 군락지의 생육 환경은 전형적인 하계 다우형 기후를 보였고, 토양은 미사질양토로, 유기물 함량 11.42~15.61%, 전질소 함량 0.50~0.76%, 양이온 치환용량(C.E.C) 18.92~23.32c㏖/㎏, pH 4.85~5.58 범위를 나타내었다. 조사구별 전광대비 광 환경의 차이는 상대 투광율이 조사구 A가 71~76%, 조사구 B는 37~42%, 조사구 C는 65~70%, 조사구 D는 28~33%로 나타났다. 굴거리나무의 치수는 모수의 수관 밑과 경사진 곳에 집중적으로 분포하는 경향을 보였고, 광환경 조건이 상대적으로 높은 조사구 A와 C가 1,550본/ha, 1,250본/ha이었으며, 총 물질 생산량도 조사구 A가 5.37g, 조사구 C가 5.29g로 광환경 조건이 낮은 조사구 B와 D의 4.42~4.51보다 높게 나타났다. T/R율은 1~2, 엽면적비는 139.71~183.50㎠ㆍg?¹, 엽면적비는 39.68~60.66㎠ㆍg?¹, 엽건중비는 0.28~0.33㎠ㆍg?¹ 범위 내에서 광량이 적어질수록 높게 나타났다. 굴거리나무 치수의 발생과 생장은 토양내 유기물 함량보다 광량이 많은 영향을 미치는 것으로 판단되며 시설양묘 적용시 전광대비 65~70% 이상의 광환경의 관리가 굴거리나무의 초기 생장에 중요한 역할을 미칠 것으로 판단된다. This study aimed to examine foundational data for container seedling production with the subject of Daphniphyllum macropodum community in Mt. Naejang National Park. To achieve the goal, it investigated the growth characteristics of young tree seedlings growing in places with different light intensity environment. Regarding the growth environment of Daphniphyllum macropodum community, it was typical heavy rain summer climate, and the soil was silt loam with the organic content as 11.42~15.61%, total nitrogen as 0.50~0.76%, cation exchangeable capacity (C.E.C) as 18.92~23.32 c㏖/㎏, and pH as 4.85~5.58. About light intensity environment changed by research plots, relative transmittance of solar radiation was 71~76% in plot A, 37~42% in plot B, 65~70% in plot C, and 28~33% in plot D. The seedlings tended to be intensively distributed either under the crown of their mother tree or in the slope site, and plot A and C where light intensity environment is relatively more favorable showed 1,550 tree/ha and 1,250 tree/ha. Total biomass production of Daphniphyllum macropodum seedlings was 5.37 g in plot A and 5.29 g in plot C, so they were higher than 4.42~4.51 g in plot B and D with relatively less favorable light intensity environment. The T/R ratio was 1~2, leaf area rate was 139.71~183.50 ㎠ㆍg?¹, leaf area ratio was 39.68~60.66 ㎠ㆍg?¹, and leaf dry weight ratio grew higher in the range of 0.28~0.33 ㎠ㆍg?¹ as the intensity of radiation became less. It is thought that in the generation and growth of Daphniphyllum macropodum seedlings, the intensity of light has more effects than the organic content in soil. And it is also thought that in the application of container seedlings production, light environment management over 65~70% to full sun light intensity will affect significantly the initial growth of Daphniphyllum macropodum.

인위적인 수분처리에 대한 묘고생장 결과 물푸레나무는 수분처리의 영향을 크게 받지는 않았으나, 토양수분이 감소할수록 생장이 감소하였고, 들메나무는 상대적으로 토양수분이 높은 처리구(78~90%)에서 높은 생장을 보였다. 물푸레나무와 들메나무의 큰원직경 또한 토양수분이 감소할수록 생장이 감소하는 경향을 보였다. 물질생산량의 변화는 물푸레나무의 경우 잎, 줄기, 뿌리 등 건중량이 각 처리구별로 토양내 수분이 낮아질수록 통계적으로 유의성을 보이면서 감소하는 경향을 나타냈으며, 토양수분이 78~90%(A)인 처리구에서는 상대적으로 18~30%(D)처리구에 비해 약 2배 이상 높은 물질 생산량을 나타냈다. 들메나무도 각 처리구간에 차이를 보이면서 A처리구와 D의 처리구에서는 통계적으로 유의성을 보였다. 이는 토양수분이 묘목의 수세 약화 및 잎을 포함한 조직의 연화 등 생리적인 부분에 영향을 미치는 것으로 생각된다. 물푸레나무와 들메나무의 엽 특성중 SLA는 토양수분처리에 따라 통계적으로 유의성을 보이진 않았지만 처리구간 수분함량이 적을수록 감소하는 경향을 나타냈다. 그러나 LAR과 LWR의 경우에는 각 처리구간 토양내 수분함량이 적을수록 통계적으로 유의성은 나타나지 않았지만 증가하는 경향을 나타냈다. Although the result of the tree height growth after water treatment, Fraxinus rhynchophylla has little affection by the artificial water treatment, the growth showed decreased tendency as the soil moisture decreased, and F. mandshurica showed high growth in relatively high soil moist 78~90% treated area, The growth of root collar diameter of F. rhynchophylla and F. mandshurica also showed decreased tendency as soil moisture decreased. The changes of biomass according to dry weight of root, stem, leaves of F. rhynchophylla demonstrating statistical significance as moisture contents of soil is lower showing decreased biomass tendency and in the treatment of 78%~90%(A) moisture content showed more than double the higher biomass compare to the treated area of 18~30%(D) moisture contents. Also F. mandshurica showed statistical significance in A and D treatment demonstrating differences among each treatment. This can be purported to have physiological effects like weakening of seedling and softening of tissues including leaves as soil moisture decreased. Ultimately it is regarded to the main reason of unsatisfactory growth for F. rhynchophylla and F. mandshurica that are weak to drought resistance. SLA, which is one of the special traits of leaf area of F. rhynchophylla, didn't show statistical significance between moisture process, it demonstrated decreased tendency as the moisture content interval is minimal. LAR and LWR showed increased tendency while moisture content didn't show statistical significance between treatments as they are minimal.

Purpose: This study was aimed at evaluating the timing of clinical recurrence after surgical removal of the primary tumor. Methods: The hazard rate for recurrence during the first 5 years after surgery was studied in 1,225 female patients from 1995 to 2003 at Kyungpook National University Hospital. Subset analyses were performed according to menopausal status and axillary lymph node involvement. Results: The group of premenopausal women has one peak hazard rate in the 18~24 month period after surgery, while that of postmenopausal women has two peaks at 18~24 months and 42~48 months. The hazard rate of node positive group is much higher than node negative group at all periods. In the premenopausal group, patients with less than 3 node metastases have a peak hazard rate at about 18~24 months, while those with more than 4 lymph node metastases have that in 6~12 months. In the postmenopausal group, patients with less than 3 node metastases have the peak hazard rate at 18~24 months, while more than 4 lymph node metastases have two peaks at 18~24 months and 42~48 months. Conclusion: Both premenopausal and postmenopausal groups similarly show the peaked hazard rate of recurrence at about 2 years after surgery. In premonopausal young women, the status of nodal metastasis affects early recurrence, while in postmenopausal women, more nodal metastasis related with late recurrence at about 45 months. Menopausal status according to axillary node involvement shows the different recurrence pattern.

Background / Aims : Hepatocellular carcinoma(HCC) is a drug -resistant tumor. The expression of a multidrug resistant gene, P-glycoprotein(P-gp) is a major mechanism of drug resistance. The aims of our study were, firstly, to observe the expression rate of P-gp in HCC tissue obtained by percutaneous fine needle aspiration(PCNA) from stage IV HCC patients; secondly to examine the association between P-gp and chemotherapeutic response ; and finally to investigate the correlation between p53 protein expression and P-gp expression. Subjects and Methods : We studied 29 cases of stage IV HCC treated by systemic chemotherapy. Expression of P-gp and p53 were evaluated by immunohistochmical staining of HCC tissue with human monoclonal anti body, JSB-1(Anti P-gp ) and DO-7(Anti p53), respectively. We analyzes the results of immunohistochmical staining of HCC tissues of the patients in relation to chemotherapeutic response and other clinical charateristics. Results : The expression rate of P-gp was 27.5%. Partial response to anti-cancar chemotherapy was observed in 16.7% of the to chemotherapeutic response, none of the response to anti-caner chemotherapy was observed in 16.7% of the patients. Although we could not see a statisrically significant association between to chemotherapeutic response expression and chemotherapeutic response , none of the response patients showed chemotherapeutic response P-gp expression. p 53 protein expression was found in 45% of the patients. There was no significant correlation between p 53 protein expression and P-gp expression. Conclusions : Although the number of our study subjects was small, chemotherapy- responsive patients didn't show P-gp expression. P-gp expression might be used as a predictor of response to potentially toxic anti-cancer chemotherapy in HCC patients. Futher study is warranted to confirm our results.

Primary sclerosing cholangitis (PSC) is a progressive, inflammatory disease affecting extra- and intra- hepatic bile ducts with characteristic radiologic and histologic findings. PSC is frequently associated with ulcerative colitis (UC) and the incidence of cholangiocarcinoma is increased in those patients with PSC and UC. We experienced a case in which primary sclerosing cholangitis, ulcerative colitis, and peripheral cholangiocarcinoma were combined. The patient was a 37-year-old female and complained of jaundice. To our knowledge, this is the first report which has presented the association of three disease entities in Korea.

Background/Aims: About 15% of Korean hepatocellular carcinoma(HCC) are negative both of Hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus (anti-HCV)in their sera. They can be classified as a non-B, non-C hepatocellular carcinoma group(NBNC group). The aims of our study were, firstly, to describe the clinical characteristics of Korean NBNC HCC and compare them with those of HBsAg-positive HCC(HBV group) and anti-HCV-positive HVV(HCV group). Secondly we wanted to assess the frequency of viremia of HBV, HCV and transfusion-transmitted virus(TTV)in NBNC HCC patients. Methods : we prospectively collected clinical data and sera from 113 NBNC HCC patients and performed PCR for HBV DNA, HCV RNA and TTV DNA. We also collected clinical data from 125 HBsAg-positive HCC patients during a similar period. Results : The mean age of the NBNC HCC group was 59 years, in-between that of the HBV and the HCV groups. A History of heavy alcohol drinking was found in 48% of the NBNC HCC group. This was significantly higher than that of the HBV group, but similar to that of the HCV group. Serum α FP level in the NBNC HCC group was more frequently in the normal range compared to that in the HBV and HCV groups. The detection rates of HBV DNA, HCV RNA and TTV DNA in the NBNC HCC group were 17%, 13% and 67% respectively. Conclusions : The NBNC HCC patients seemed to comprise a heterogeneous group of various etiologies and clinical presentations. About one third of these patients displayed evidence of viremia of HBV or HCV.
