The differential diagnosis of pleural effustioin remains to be solve. The aim of this study was to evaluate the diagnostic values of the fibronectin concentration and andevosine deaminase activity in the differentiation between tuberculous and malignant pleural effusion. The activity of adenosine deaminase and the concentration of fibronectin were investigated in pleural effusions from 10 patients with tuberculous pleurisy and 10 patients with malignant effusion. The mean ADA activity was significantly higher in the tuberculous pleurisy (74.01±24.05 U/L) than in the malignant pleural effusion(15.46±13.08 U/L). Based on the lowest value of ADA activity found in the tuberculous pleurisy (45 U/L), the test had a sensitivity of 1 and a specificity of 1. There was no difference between the fibronectin concentration of pleural fluid in the tuberculous pleurisy (306.62±50.52mg/ml) and in the malignant pleural effusion (250.50±144.28㎍/ml) By discriminant analysis, the ADA activity was good indicator for differentiation of tuberculous from malignant pleural effusion (% of correctly classified = 95%) and the simultaneous determinations of both parameters in not more efficient tn the differential diagnosis than in determination of only ADA activity. The present study showed that determination of ADA in pleural fluid is of great value in the differentiation between tuberculous pleurisy and malignant pleural effusion.

언론자유의 법적 제한에 관한 고찰 : 국가안보에 대한 언론자유의 제한을 중심으로

The press and the state power have a long history of conflict over the issue of "The freedom of the press" vs. "The national security". The press has made continuous effort to expand its freedom for the sake of the fundamental right to be informed but it often infringes with the national security. The state power or the Government wants to protect the state secrets. In the democratic system, the balance between the freedom of the press and national security should be maintained but the conflicts arise when each side tries to expand its right at the expense of the others. The conflicts generally arise due to the differences in the interpretation of the term "The state secrets". The present study aims to seek ideas about how to reconcile these conflicts and overcome the adversary relationship between the press and the state power. The study begins with the overview of general principles applied in the limitation of press-freedom. Then, it follows the examination of the concept and scope of the national security. The various statutes regulating the relationship between the freedom of the press and national security enacted out of the actual needs of their societies rather than theoretical necessities. Finally the same issues are examined in the Korean context. This paper examines the various questions arising from the relationship between the freedom of the press and the national security in the actual situations of Korea. In doing so, it reviews the actual statutes that have limited the freedom of the press in the past. The conflicting relationship between the press and the state power can only be improved by reducing distrust between the two parties and by sacrifing their own interests for the sake of the great cause of the genuine national interest.

Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.

선제형,박진석,한민석,김수항,김우진,박인형,이숭,유종선,박찬국 朝鮮大學校 附設 醫學硏究所 2006 The Medical Journal of Chosun University Vol.31 No.3

Gastritis cystica profunda (GCP) is a rare disease characterized by gastric foveolae elongation along with hyperplasia and cystic dilatation of the gastric glands extending into the tissue beneath the submucosa. GCP mainly develops at the gastroenterostomy stoma but can arise in a stomach that has not undergone surgery. The proposed pathogenesis is related to chronic inflammation, ischemia and the presence of a foreign body. GCP may present as a submucosal tumor, Polyp or a giant gastric mucosal fold. Endoscopic ultrasonography (EUS) is an effective diagnostic method for differentiating GCP from protruding and elevated gastric lesions. We report a case of GCP along with the endoscopic and EUS findings that were indistinguishable from a malignant submucosal tumor.

N/A Background/Aims: Liver fibrosis by the progression of the chronic process of the liver disease induces deformed microcirculations of the hepatic lobules and this eventually resulted in portal hypertension. Angiogenic stimulant factors are physiologically activated in order to repair the tissue damage. Overexpression of angiogenic factors, however, can stimulate neovascularization as in a formation of the hypervascular tumor that liberates uncontrolled overgrowing of the tumor cells. To elucidate the dynamic changes of the serum concentration of basic fibroblast growth factor(bFGF) and angiogenin in chronic liver diseases, this study is intended to employ an ELISA out of pathologically proven patients. Methods: Sera taken out of the 44 patients with chronic persistent hepatitis(5 cases), chronic active hepatitis(6 cases), liver cirrhosis(19 cases) and hepatocellular carcinoma(14 cases) were tested for bFGF and angiogenin employing Quantikine' ELISA Kits (R & D Systems Inc. Minneapolis, MN) that pathological diagnosis was proven )ater. The statistical analysis was evaluated by students t-test. Results: Serum mean value and standar<I error of bFGF concentration(pg/ml) was 11.851.98 in 19 cases of liver cirrhosis, 9.86+2.35 in 14 cases of hepatocellular carcinoma, 9.48+4.57 in 6 cases of chronic active hepatitis, and 8.29+2.63 in 5 cases of chronic persistent hepatitis. Mean value and standard error of angiogenin concentration (ng/ml) of the sera was 238.92+50.95 in 5 cases of chronic persistent hepatitis, 184.47+12.75 in 6 cases of chronic active bepatitis, 131.36+10.99 in 19 cases of liver cirrhosis, and 211.03+19.08 in 14 cases of hepatocellular carcinoma, respectively. Serum angiogenin concentration in liver cirrhosis was significantly lower than that in chronic persistent hepatitis(p=0.0033(I), and than that in chronic active hepatitis(p=0.018673). Angiogenin concentration in hepatocellular carcinoma was very significantly elevated, when compared with the level of the liver cirrhosis investigated (p=0.000569). Conclusions: These data suppoit that persistent inflammatory insults in chronic hepatitis were compensated by the elevation of angiogenin, but complete fibrosis as in liver cirrhosis showed the depressed level of angiogenin. Again, emerging of the hepatocellular carcinoma is accompanying with the elevated stitnuli of angiogenin for the neovascularization. In contrast, bFGF in this study was statistically not significant but may be related with fibrosis and reconstruction of microvascular system accompanying with progression of chronic parenchymal liver diseases to liver cirrhosis.(Korean J Gastroenterol 1996; 28:806-814)

N/A Objectives: Patients with chronic liver disease are at increased risk to develop metabolic bone disease. Although the etiology of the osteopathy in patients with primary biliary cirrhosis has not been defined, vitamin D deficiency and calcium malabsorption have been suggested as possible pathogenetic factors. In Korea, Patients with postnecrotic liver cirrhosis due to chronic hepatitis B are numerous, however, data on the prevalence and severity of osteopenia in these patient are rare. This study was performed to elucidate the mechanism of osteopenia and to examine its severity in postnecrotic liver cirrhosis. Methods: Thirty four patients with postnecrotic liver cirrhosis and thirty controls matched in age and sex were included in this study group. To obtain bone mineral density of lumbar spines in postnecrotic liver cirrhosis and control groups, measurements and comparisons of following tests were performed: Dual energy xray absorptimetry, serum calcium, serum osteocalcin, and serum 25 (OH) vitamin D. In addition, initial morning urine sample was collected to measure pyridinoline crosslinks. Results: 1) The average bone density of lumbar spines was 1.03±0.03 gm/cm² in postnecrotic liver cirrhosis group and 1.15±0.02 gm/cm² in normal controls (p<0.01). 2) The prevalence of osteopenia in the lumbar spine was 50% in postnecrotic cirrhotics compaired to 13% in controls. 3) The levels of serum calcium, 25 (OH) vitamin D and serum osteocalcin were 2.12±0.04 mmol/L, 7.38±1.00 ng/ml and 1.92±0.18 ng/ml in postnecrotic liver cirrhosis, 2.54±0.05 mmol/L and 21.68±1.90 ng/ml and 3.31±0.31 ng/ml in control group (p<0.05). 4) The levels of urinary pyridinoline crosslinks in postnecrotic liver cirrhosis and control were 82.87±7.50 nM/mM and 43.48±3.52 nM/mM, respectively (p<0.05). Conclusion: This study suggests that the incidence of lumbar osteopenia is more common in postnecrotic liver cirrhosis patients. In addition, its pathogenesis is related to vitamin D deficiency, decreased osteoblastic activity, and increased osteoclastic activity. Further studies including several hormones and histopathology of bones are needed to clearly define the mechanisms of osteopenia in postnecrotic liver cirrhosis.

Backgroud:Liver fibrosis by the progression of the chronic processes of the liver diseases induces deforrned microcirculations of the hepatic lobules. And this eventually resolted in portal hypertension. On the other hands, angiogenic stimu4nt factors are physiologically activated in order to repair the tissue damage. Overexpression of angiogenic factors, however, can stimulate neovascularization as in a fonnation of the tumor that liberates uncontrolled overgrowing of the tumor cells. Methods: To elucidate the dynamic changes of the serum concentration of angiogenin in chronic liver diseases, this study is intended to employ an ELISA in 44 pathologically proven patients. Quantikiae_(TM) human angiogenin kit (R & D,systems Inc. Mmneapolis, MN) was used for this investigation. Results:Mean value and standard error of angiogenin concentration (ng/ml) of the sera was 238.92+ 50.95 in 5 cases of chronic persistent hepatitis, 184.47+ 12.75 in 6 cases of chronic active hepatitis, 131.36+ 10.99 in 19 cases of liver cirrhosis, and 211.03+ 19.08 in 14 cases of hepatocellular carcinoma, respectively. Serum angiogenin level in the liver cirrhosis was significantly lower than in chronic persistent hepatitis(p=0.00336), and than in chronic active hepatitis(p=0.018673). Angiogenin concentration in hepatocellular carcinomas was significantly higher than the level of the liver cirrhosis investigated(p=0.00569). Conclusions:These data support that persistent inflammatory insults in the chronic hepatitis were compensated by the elevation of angiogenin but complete fibrosis as in liver cirrhosis showed the depressed level. And emerging of the hepatocellular carcinoma is accompanied by the elevated stimuli of angiogenin for the neovascularization.
