In order to examine the effect of extrahepatic cholestasis induced by common bile duct ligation on the hepatic function, the pharmacokinetics of antipyrine and d-propranolol were investigated in rats. In addition, in an attempt to observe the degree of direct hepatic injury, light and electron microscopic observations and conventional pathologic test using serum were performed. Five days after common bile duct ligation, antipyrine(15 mg/kg) and d-propranolol(3 mg/kg) were intravenously administrated to the rats, respectively. The total clearances of antipyrine and d-propranolol were significantly(p<0.05) decreased. Because hepatic clearance of antipyrine poorly extracted by the liver and that of d-propranolol highly extracted by the liver are respectively dependent on the hepatic intrinsic clearance and the hepatic blood flow, it may be concluded that extrahepatic cholestasis following five days after common bile duct ligation decreased the hepatic intrinsic clearance and the hepatic blood flow. SGPT, SGOT, cholesterol, bilirubin(total bilirubin, direct bilirubin) and alkaline phosphatase were significantly increased(p<0.05). The proliferation of bile ducts was prominent, and degeneration and necrosis of hepatocytes were observed by light microscope. Also, ultrastructurally, bile canaliculi were containing the amorphous materials and losing microvilli, and SER and RER in hepatocytes were dilated and vacuolated.

목 적 : 담도 폐쇄증의 생존율을 높이기 위해서는 조기 진단 및 치료가 필수적이다. 빠른 감별 진단이 중요함에도 불구하고 DISIDA 스캔은 담도 폐쇄증을 진단하는데 있어 민감도(100%)는 높으나 특이도가 낮아 진단 가치가 낮다. 그러나 감별 진단을 할 시간이 비교적 충분한 경우에는 시도할 수 있는 검사이므로 DISIDA 스캔의 시행 가치가 있는 임상적 기준을 찾아보고자 한다. 방 법 : 1996년 4월부터 2005년 12월까지 경북대학교병원 소아과에 신생아 또는 영아기 담즙정체증으로 내원한 환자 중 담도 폐쇄증과 감별이 필요하였던 총 87명의 영아(남아 58명, 여아 29명)를 대상으로 DISIDA 스캔을 시행하였다. 대상 환아의 나이는 평균 59.1일(생후 18-139일)이었다. 환아들을 후향적으로 담도 폐쇄증 환아 군, 비담도 폐쇄증군(신생아 간염 증후군, 총 정맥영양 관련 담즙정체증 포함)으로 분류하였다. 비담도 폐쇄증군은 DISIDA 스캔에서 소장 내 방사능이 보이는 군과 보이지 않은 군으로 나누었다. 환아의 최종 진단과 DISIDA 스캔 결과에 따라 5개 군으로 분류한 다음 각 환자의 나이, 직접 빌리루빈, AST, ALT, ALP, GGT 간의 상관 관계를 산점도를 통해 비교 분석하였다. 분석한 그림을 바탕으로 환자를 직접 빌리루빈이 5 mg/dL 이상인 군과 5 mg/dL 미만인 군으로 나누어 담도 폐쇄증에 대한 DISIDA 스캔의 진단적 민감도, 특이도, 정확도를 비교 분석하였다. 결 과 : DISIDA 스캔을 시행한 87명 중 담도 폐쇄증 환아는 16명 모두에서 소장 내 방사능이 나타나지 않았다. 담도 폐쇄증이 아니었던 71명 중에서는 25명(35%)에서 소장 내 방사능이 보이지 않아 높은 위양성 결과를 보였다. 담도 폐쇄증에 대한 DISIDA 스캔의 진단 민감도와 특이도는 각각 100%(16/16)와 70.4%(50/71)였으며 정확도는 75.9%(66/87)였다. 총 87명의 환아들을 5개 군으로 분류한 후 산점도를 통해 비교 분석한 결과 나이, AST, ALT, ALP, GGT 등은 최종 진단을 예측하는데 도움을 주지 못하였으며 DISIDA 스캔의 진단율에도 영향을 주지 않았다. 직접 빌리루빈 수치 5 mg/dL 미만인 경우 위양성률은 9.7%(5/31)였으나 5 mg/dL 이상인 경우의 위양성률은 42.5%(17/40)에 달하였다. 결 론 : 신생아 담즙정체성 간질환에서 담도 폐쇄증 감별을 위한 DISIDA 스캔은 직접 빌리루빈이 5 mg/dL 이상일 경우 진단적으로 유용하지 않으므로 가능한 다른 진단법을 신속히 시행하여 담도 폐쇄증을 진단하는 것이 바람직할 것으로 생각한다.

방사선이 간 담도계에 미치는 영향을 검토하기 위하여 선형가속장치에 의한 4MV X선 10, 15 및 20Gy를 흰쥐의 간 일부에 각각 조사한 후 1, 2, 4 및 8주에 간 담도계 손상의 지표로 이용 되고 있는 혈중 alkaline phosphatase 및 bilirubin의 함량을 측정 검토한 결과 먼저 alkaline phosphatase의 활성은 전 조사선량군에서 상승경향을 나타내었으며, 특히 20 Gy 8주군에서 현저한 상승을 나타내었고, 혈중 bilirubin의 함량도 시간 경과와 함께 상승경향을 나타내었으며, 20 Gy 8주군은 유의하게 상승하였다. 이상의 실험 성적을 종합해 볼때 방사선 조사로 인한 간 담도계의 장해는 조사된 선량에 따라 10 및 15 Gy군에서는 기간 경과와 함께 점차 회복되는 경향이었으나, 20 Gy군에서는 오히려 증가 된 것으로 보아 부분조사에서도 20 Gy가 한계선량임을 확인할 수 있었으며, 방사선치료시 간의 일부가 조사야에 포함되지 않도록하는 주의가 필요하다고 생각된다.

본 연구는 용혈의 영향과 허용 hemolysis index (HI)를 조사하기 위해 용혈된 검체와 재채혈된 검체의 결과를 비교하였다. 용혈 전·후, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), amylase (Amy), direct bilirubin (D-bil), total bilirubin (T-bil), creatine phosphokinase (CK), gamma glutamyl transferase (GGT), iron, potassium (K), lactate dehydrogenase (LDH), magnesium (Mg), phosphorus (Phos), total protein (TP), uric acid (UA) 항목에서 유의미한 결과를 보였다. LDH, K, iron, AST, CK, GGT, TP, Amy, Phos는 용혈 정도와 결과 사이에 높은 상관관계가 있었다. Quality control (QC) high standard deviation (SD)을 이용하여 구한 허용 HI, HI^QChigh를 비교했을 때 AST, D-bil, CK, LDH는 비슷했지만 Amy, GGT, K, iron, Phos, TP는 장비의 cut-off HI보다 낮은 HI에서부터 영향 받았으며 ALP, ALT는 높게 나왔다. 그리고 paired t-test를 통해 유의미한 결과가 없었던 albumin, cholesterol, triglyceride 항목에서도 HI>200에서는 유의미한 결과가 나왔기 때문에 재채혈하는 것이 바람직하다고 생각되며 HI<100일 때 영향을 받는 항목들이 있었던 연구 결과를 기반하여 약한 용혈이 나타나는 HI>50부터 용혈 기준을 설정하는 것을 권장한다.

Glucuronidation by the uridine diphosphateglucuronosy-ltransferase 1A enzymes (UGT1As) is a major pathway for elimination of particular drugs and endogenous substances, such as bilirubin. We examined the relation of eight single nucleotide polymorphisms (SNPs) and haplotypes of the UGT1A gene with their clinical factors. For association analysis, we genotyped the variants by direct sequencing analysis and polymerase chain reaction (PCR) in 218 healthy Koreans. The frequency of UGT1A1 polymorphisms, -3279T>G, -3156G>A, -53 $(TA)_{6>7}$, 211G>A, and 686C>A, was 0.26, 0.12, 0.08, 0.15, and 0.01, respectively. The frequency of -118 $(T)_{9>10}$ of UGT1A9 was 0.62, which was significantly higher than that in Caucasians (0.39). Neither the -2152C>T nor the -275T>A polymorphism was observed in Koreans or other Asians in comparison with Caucasians. The -3156G>A and -53 $(TA)_{6>7}$ polymorphisms of UGT1A were significantly associated with platelet count and total bilirubin level (p=0.01, p=0.01, respectively). Additionally, total bilirubin level was positively correlated with occurrence of the UGT1A9-118 $(T)_{9>10}$ rare variant. Common haplotypes encompassing six UGT1A polymorphisms were significantly associated with total bilirubin level (p=0.01). Taken together, we suggest that determination of the UGT1A1 and UGT1A9 genotypes is clinically useful for predicting the efficacy and serious toxicities of particular drugs requiring glucuronidation.

In western medicine, there are some reports about herbal medicine induced hepatitis, but in oriental medicine, there are few reports about that. We experienced one case of drug acute cholestatic-hepatitis in the treatment of oriental medicine for HNP. We treated the patient with acupuncture, physical therapy and herb medicine. The patient's symptoms improved after two weeks of treatment. In the course of treatment, the patient intermittently complained of general weakness, nausea, yellowish urin, dyspepsia, and abdominal discomfort. We recognized that total bilirubin(7.2mg/dl), direct bilirubin(5.5mg/dl), serum transaminase(AST 360U/L, ALT 354U/L), alkaline phosphatase(16.6 K/A), urobilinogen(++) and bilirubin(++) were elevated. We diagnosed drug induced hepatitis. We stopped giving herb medicine and began giving Saeng gan gunbi-tang and Injin-oryung-san. Saeng gan gunbi-tang and Injin-oryung-san have been used to treat hepatic disease and have been known to have beneficial effects. After 3weeks on medication, the clinical symptoms and liver function improved. So, we report this case to bring more attention to the safety and toxicity of herbal medicine.

Acute hepatitis is caused by virus, alcohol. toxins and drugs. Clinical symptoms of acute hepatitis are severe fatigue, jaundice, nausea, hepatomely, lymphadenopathy. We encountered two cases of acute hepatitis, one C type viral hepatitis and the other hepatitis by overuse of medicine. The symptoms of the latter are severe fatigue, petechia and heartburning. The symptoms of the latter are severe fatigue, nausea, dyspepsia, yellow urine and skin. We recognized that total bilirubin. direct bilirubin, serum transaminase, alkaline phosphatase and gamma glutamyl transferase were elevated. We treated both patients with herb medicine(Gagamsaenggan-tang). Gagamsaenggan-tang has been used to hepatic diseases and have been known to have beneficial effects. The patients' symptoms began to improve after about two weeks of treatment. After 3 weeks on medication, the clinical symptoms and liver function of two patients were improved.

This work was conducted to investigate dietary supplementation of oyster mushroom fruiting bodies on biochemical and histological changes in hyper and normocholesterolemic rats. Six-week old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. Feeding a diet containing a 5% powder of Pleurotus ostreatus fruiting bodies to hypercholesterolemic rats reduced plasma total cholesterol, triglyceride, low-density lipoprotein (LDL), total lipid, phospholipids, and LDL/high-density lipoprotein ratio by 30.18, 52.75, 59.62, 34.15, 23.89, and 50%, respectively. Feeding oyster mushrooms also significantly reduced body weight in hypercholesterolemic rats. However, it had no adverse effects on plasma albumin, total bilirubin, direct bilirubin, creatinin, blood urea nitrogen, uric acid, glucose, total protein, calcium, sodium, potassium, chloride, inorganic phosphate, magnesium, or enzyme profiles. Feeding mushroom increased total lipid and cholesterol excretion in feces. The plasma lipoprotein fraction, separated by agarose gel electrophoresis, indicated that P. ostreatus significantly reduced plasma ${\beta}$ and pre-${\beta}$-lipoprotein but increased ${\alpha}$-lipoprotein. A histological study of hepatic cells by conventional hematoxylin-eosin and oil red O staining revealed normal findings for mushroom-fed hypercholesterolemic rats. These results suggest that a 5% P. ostreatus diet supplement provided health benefits by acting on the atherogenic lipid profile in hypercholesterolemic rats.
