Three-years-old Pinus koraiensis seedlings transplanted in the artificially acidified forest soils during growing period for 182 days from April 11 to October 9, 2002. That soil was mixed with artificial acid solution at 0, 10, 30, 60 and 90meq H ` per 1L of soil. The result was as following. Some seedlings withered up at 60 and 9OmeqH` treatment after 8 weeks. Seedling growth at control after 182 days was greater than 10, 30, 60, 90meqH` treatment. Also, Relative Growth Rate(RGR) and Net Assimilation Kate(NAR) increased at 10 and 30meqH^(+) treatments comparing to control, but those decreased at 60 and 90meqH` treatments. Leaf Weight Ratio(LWR) did not change by each treatment. There was a significantly positive correlation(r=0.99, ?0.001) between relative total dry weight(TDW) of seedlings and (Ca+Mg+K)/Al molar ratio in soil. When the (Ca+Mg+K)/Al molar ratio was l.0,the TDW decreased about 40%.

The ash content, mineral composition, total phenolics, antioxidant capacity, and neuroprotective effect of the antlers of deer fed with herb-incorporated feedstuff (HFS) or normal feedstuff (NFS) were comparatively evaluated. The contents of ash and mineral of the antler of deer fed with HFS were significantly lower than its counterpart. The ash and mineral contents of deer antlers decreased generally from the upper section toward the tip section. The ratios of Ca/ash, Ca/P, and Ca/Fe of antler of deer fed with HFS were lower than those of antler of deer fed with NFS. Antlers of deer fed with HFS had higher total phenolics, nitrite scavenging capacity, and antioxidant capacity than those of deer fed with NFS. Antlers of deer fed with HFS or NFS showed in vitro neuronal protection of PC-12 cells against oxidative stress in a dosedependent manner, where antler of deer fed with HFS generally had higher cellular viability than NFS. These results above suggest that the incorporation of the medicinal herbal complex into feedstuff may improve the biological effects of deer antlers.

저자는 1991년 4월부터 1991년 8월까지 경상대학교병원을 내원한 위 질환자 87명과 위장관 증상을 호소하지 않은 만성 표재성 위염 환자 20명을 대상으로 혈장과 위액 그리고 소변에서 vitamin C 농도를 측정하여 다음과 같은 결론을 얻었다. 1) 위액의 vitamin C 농도는 급성 위염군(1.29±1.86mg/dl)과, 증상이 있는 만성 표재성 위염군 (1.34±0.96mg/dl), 만성 위축성 위염 및 화생성 위염군(1.21±1.07mg/dl), 위궤양군(1.41±1.12mg/dl), 위암군(0.62±0.51mg/dl)에서 무증상인 만성 표재성 위염군(2.54±1.86mg/dl)에 비해 통계적으로 유의하게(p<0.05) 감소되어 있었다. 특히 위암 환자군에서 가장 낮게 측정되었다. 2) 혈장에서의 vitamin C 농도는 질환군간에 유의한 차이를 보이지 않았다. 3) 위액의 산도가 4.0이상인 저산증 환자군 (0.96±0.79mg/dl)에서 위액의 vitamin C 농도는 산도가 4.0이하인 군(1.97±1.49mg/dl)에 비해 통계적으로 유의하게(p<0.05)감소되어 있었다. 4) 위액의 산도가 4.0 이상인 저산증 환자군과 4.0 이하인 군에서 혈장(1.09±0.47 vs 1.23±0.51mg/dl)과 소변(3.46±3.24 vs 3.74±2.92mg/dl)에서의 vitamin C 농도는 유의한 차이를 보이지 않았다. 5) 혈장에 대한 위액의 vitamin C 농도비는 무증상인 만성 표재성 위염군에 비해 증상이 있는 만성 표재성 위염군, 만성 위축성 위염 및 화생성 위염군 그리고 위암군에서 통계적으로 유의하게(p<0.05)감소되어 있었으나 급성 위염군과 위궤양군에서는 유의한 차이를 보이지 않았다. 6) 혈장에 대한 소변의 vitamin C 농도비는 질환군간에서 통계적으로 유의한 차이를 보이지 않았다. The level of vitamin C was measured from the specimens of plasma, gastric juice, and urine of the symptom-free subjects of chronic superficial gastritis and other gastric diseases by 2.4-dinitropheny-lhydrazine method. The object of this study is to know the relationship between vitamin C concentration of tissue fluids and gastric diseases. Follwing results have been obtained : 1) The levels of vitamin C in the gastric juice of the patients of symptomatic chronic superficial gastritis, chronic atrophic gastritis and metaplastic gastritis, gastric ulcer, and gastric cancer were lower than those of the symptom-free subjects of chronic superficial gastritis and in the case of the patients with gastric cancer, the level was the lowest. 2) The plasma level of vitamin C concentration was not different among the specimens from the groups of the patients. 3) In the case of hypochlorhydria (pH>4.0), the level of vitamin C concentration in the of gastric juice was low. However the plasma and urine vitamin C concentrations were not different, compaired to that of the patients with gastric pH below 4.0. 4) The ratios of the gastric juice to plasma vitamin c concentrations was low in the groups of symptomatic chronic superficial gastritis, chronic atrophic gastritis and metaplastic gastritis, and gastric cancer, but the ratios were not low in patients of acute gastritis and gastric ulcer, compared to the symptom-free subjects of chronic superficial gastritis (p<0.05). 5) The ratios of the urine to plasma vitamin c concentrations in the groups of various gastric diseases were not different to those of the symptom-free subjects of chronic superficial gastritis.

1989년 5월부터 1990년 7월까지 경상대학교 병원에 내원한 218예의 간질환 환자를 대상으로 미국 Ortho Diagnostic Systems사의 효소결합면역측정법을 이용한 C형 간염바이러스 항체검사를 시행하여 다음과 같은 결과를 얻었다. 1) 총 218예의 급만성 간질환자중 208예(12.8%)에서 anti-HCV 양성이었다. 2) 총 28예의 anti-HCV 양성인 환자는 각 질환별로 만성간염 83예중 11예(13.3%), 간경변중 25예중 1예(7.1%)였다. 그러나 HBsAg 보유자 53예는 anti-HCV 가 모두 음성이었다. 3) IgM anti-HAV, IgM anti-HBc, anti-HDV 및 HBsAg이 음성이고 급성 NANB형 간염으로 진단된 5예중 anti-HCV 양성인 경우는 1예도 없었고, 만성 NANB형 40예중 6예(15.6%)에서 anti-HCV 양성이었다. 4) HBsAg음성인 환자 68예중 11예(16.25)가 anti-HCV양성이었으며, 각 질환별로 만성간염 40예중 6예(15%), 간경병증 9예중 3예(33.3%), 원발성간암 14예중 2예(14.3%)였다. 5) Anti-HCV 양성인 28예중 17예(60.7%가 HBsAg을 보유하였고, 각 질환별로 만성간염 11예중 5예(45,5%), 간경변중 8예중 5예)(62.5%), 원발성간암 8예중 6에(75%), 급성간염 1예중 1예(100%)였다. 6) Anti-HCV 양성인 28예중 5예917.9%) 만이 수혈 경험이 있고 이 5예중 2예는 HBsAg도 양성이었다. 이상의 결과에서 NANB형 간염혼자의 HBsAg 음성인 만성간질환 환자에서 anti-HCV 양성율이 다른 보고에 비해 낮은 빈도를 보였다. 그리고 anti-HCV 음성인 간질환 환자에서도 수혈의 경험이 없는 경우가 대부분이었다. The prevalence of antibody against hepatitis C virus (anti-HCV) was investigated in 218 patients with various liver diseases from May 1989 to July 1990. The presence of anti-HCV was detected by Ortho HCV antibody ELISA test. The results were summarized as follows: 1) Overall, antibody to HCV (anti-HCV) was detected in twenty-eight (12.8%) of 218 patients with various liver diseases. 2) Of twenty-eight anti-HCV-positive cases, eleven (13.3%) of 83 patients with chronic hepatitis. eight (32%) of 25 patents with liver cirrhosis, eight (18.6%) of 13 patients with hepatocellular carcinoma. and one (7.1%) of 14 patients with acute hepatitis were positive for anti-HCV. But, none of all 53 HBsAg carriers were anti-HCV positive. 3) In 5 patients with presumed acute NANB hepatitis, who had no IgM anti-HAV, IgM anti-HBc, anti-HDV, & HBsAg, none of them had detectable anti-HCV. Six (15.0%) of 40 patients with chronic NANH hepatitis were positive for anti-HCV. 4) Eleven (16.2%) of 68 HBsAg-negative patients had anti-HCV: six (15.0%) of 40 patients with chronic hepatitis, three (33.3%) of 9 patients with liver cirrhosis, & two (14.3%) of 14 patients with hepatocellular carcinoma. 5) The prevalence of HBsAg positivity in patients who had anti-HCV was 45.5%(5/11) in patients with chronic hepatitis. 62.5%(5/8) in patients with liver cirrhosis, 75%(6/8) in patients with primary hepatocellular carcinoma, & 100%(1/1) in patient with acute hepatitis. 6) Only five (17.9%) of 28 anti-HCV positive-patients had a history of blood transfusion. Our data show that the prevalence of anti-HCV is low in patients with NANB hepatitis and HBsAg-negative chronic liver diseases in contrast to other reports. And among patients with anti-HCV-positive chronic liver disease, most of them had no discernable history of parenteral exposure.

Biloma is abnormal extraductular collection of bile within e defined capsular space, caused by either trau- matic or spontaneous rupture of the biliary tree. Since the term $quot;Biloma$quot; had been introduced in 1979, many cases formed following trauma have been reported, yet spontaneous form has been reported rarely. Furthermore, biloma associated with biliary stone has never been reported in Korea. We report a 58-year-old woman with biloma associated with intrahepatic duct and common bile duct stones.
