The abnormal accumulation of collagen is progressive and often results in impairment of liver function, i.e. liver cirrhosis. Collagen synthesis requires several posttranslational events. Prolyl 4-hydroxylase is the key enzyme in collagen synthesis that catalyzes the hydroxylation of peptide-bound proline residues to 4-hydroxyroline.(omitted)

Objective & Method : By investigating physiological function of tri-energizer, symptoms, and organ coordination, we obtained following conclusion. Tri-energizer is the membrane structure that surrounds the five visceral organs and six hollow organs, and filled with fluid. Tri-energizer acts as the passage for the flow of qi energy. Result & Conclusion : Therefore, dysfunction of the tri-energizer is caused by abnormal evaporation and metabolism. Upper-energizer regulates cardiopulmonary function, middle-energizer regulates spleen and stomach functions, and lower-energizer regulates liver, kidneys, small and large intestines, and bladder functions. Such a functional specialization is possible by receiving the source of qi through the wall wrapping around the internal organs. Tri-energizer represents the exterior and interior relationship by acting as the membrane structure supporting the five visceral organs and six hollow organs and at the same time, as the pericardium surrounding the heart.

Objectives: To observe safety and efficacy of herbal medicine for psoriasis patients. Methods: We did retrospective chart review for 107 psoriasis patients who had been treated by herbal medicine for 2 months, and we analyzed the liver function test (LFT) results and Psoriasis Area and Severity Index (PASI) scores of before and after the treatment. Results: The mean LFT and the number of patients with abnormal LFT decreased after the treatments. More than 95% of patients with normal LFT maintained normal results at after the treatment, and only 2.1% and 4.6% patients with normal LFT showed abnormal Glutamic Oxaloacetic Transaminase (GOT) and Glutamic Pyruvic Transaminase (GPT) results at after the treatment. Also, both mean PASI scores for all patients and patients with abnormal LFT before the treatment decreased significantly. Conclusions: This study suggest that herbal medicine may be safe and effective treatment for psoriasis.

Plasma glucose levels before and after oral glucose administration have been compared in a group of 76 thyrotoxic subjects and a group of 8 normal control subjects in order to study the effect of glucose loading in thyrotoxicosis. Following were the results: 1. The mean fasting plasma glucose level was elevated in the thyrotoxic group(95.5mg%) compared to normal control group (88mg%). 2. The peak of glucose tolerance curve is at 30 minutes after glucose administration in both groups, but its mean value was 44mg% higher in thyrotoxic group than in control group. 3. The plasma glucose levels returned towards the fasting level in the later stage of the test more rapidly in thyrotoxic group than in control group. 4. 69.6% of oral glucose tolerance tests were impaired in the thyrotoxic group, and the occurance of abnormal glucose tolerance could be related to the degree of thyrotoxicity, sex and age. 5. The mechanisms of the impaired glucose tolerance in thyrotoxicosis are thought to be related to an increased rate of glucose absorption from gastrointestinal tract, abnormal liver function with decreased hepatic glycogenesis, increased glucose oxidation, decreased pancreatic release of insulin, and genetic relationship between diabetes and thyrotoxicosis.

Acute infectious mononucleosis, caused by Epstein-Barr virus(EBV), is a self limited lymphoproliferative illness that is common in adolescents and young adults. It shows many complications in multiple organ systems, but the hepatobiliary and the respiratory complication is uncommon. We report a case with thickened gallbladder wall and pneumonia as complications of acute infectious mononucleosis in a child. Also the related literature were reviewed. A 4 year old boy presented with a history of high fever, cough, and abdominal distension for 20days. Physical Examination revealed audible crackles in whole lung field and gross hepatomegaly. Chest X-ray showed pneumonia and liver function tests were abnormal. Ultrasonography and computed tomography revealed a thickened gallbladder wall and hepatosplenomegaly. The diagnosis of primary Epstein-Barr viral infection was eventually made by specific serologic tests. The patients's fever subsided 6 weeks later and pneumonia was recovered around this time. Liver function tests returned near normal 2 months later and ultrasonography of gallbladder was normal at this time.

중년 남성 근로자에 대한 알코올 섭취와 혈청지질, 간기능검사치 및 비만지표와의 관련성을 알아볼 목적으로 2013년 1월부터 12월까지의 기간 동안에 종합건강검진을 받았던 30~59세의 남성 근로자 2,175명을 대상으로 이들의 1일 알코올 섭취량과 혈압, 혈청지질, 간기능검사치 및 비만지표와의 관계를 검토하였다. 연구결과, 혈압은 음주량의 증가와 함께 유의하게 높은 값을 보였으며, LDL-콜레스테롤 및 중성지질(TG)도 음주량이 증가할수록 높아지는 경향을 보였으나 HDL-콜레스테롤은 음주량이 증가할수록 낮아지는 경향을 보였다. AST, ALT, ALP 및 ${\gamma}$-GTP도 음주량이 증가할수록 높아지는 경향을 보였으나 비만지표에서는 뚜렷한 차이가 없었다. 혈압(SBP, DBP), 혈청지질치(HDL-C, LDL-C, TG) 및 간기능검사치(AST, ALT)가 비정상으로 높아질 위험비는 소량 음주군에 비해 다량 음주군에서 유의하게 상승하였다. 위와 같은 결과는 다량의 음주는 혈압, 혈청지질 및 간기능검사치 증가와 유의한 관련성이 있었으나 비만지표와는 유의한 관련성이 인정되지 않음을 시사하고 있다.

Background : Traditional herbal medicine is used extensively among the Korean populations, and other Asian countries employ similar therapies as well. In recent years, extensive focus was laid on adulteration of the herbal medicine with liver damage. The use of herbal preparations as remedies for various medical conditions has continuously increased in Korea. Large proportions of Korean patients use herbal medicinal products, folk remedies, and health food. However, studies on the safety of herbal products are conducted on a less than sufficient basis even in the countries like Korea where herbal medicine is being used extensively. Some of the reports on the safety of herbs were done by the doctors of western medicine but lack of knowledge and misclassification led to misunderstandings. Objectives : This study aims to verify the evidences on safety of frequently used 4 herbal medications (Sipjeondaebo-tang, Bojungikgi-tang, Ohjeok-San, Yukmaijihwang-tang) in the lab animal model. Methods : Sprague-Dawley rats was treated by 4 herbal medications during 31 days. After 1 month, we checked body weight, liver weight, and serum enzyme associated with liver function. Results : There is no significant difference in body weight and liver weight after 1 month of administrations. In all experimental groups, no abnormal findings was observed in histotogical research and lab liver Functions test(AST, ALT etc). Conclusions : These four herbal medications, frequently used in oriental medicine clinics and hospitals, are safe from hepatoxic events in the lab animal model.

Objective: Approximately 30% of preeclamptic pregnancies exhibit abnormal liver function tests. We assessed liver injury-associated enzyme levels and circulating transforming growth factor beta (TGF-β) levels in an arginine vasopressin (AVP)-induced pregnant Sprague-Dawley rat model. Methods: Pregnant and non-pregnant Sprague-Dawley rats (n=24) received AVP (150 ng/hr) subcutaneously via mini-osmotic pumps for 18 days. Blood pressure was measured, urine samples were collected, and all animals were euthanized via isoflurane. Blood was collected to measure circulating levels of TGF-β1-3 isomers and liver injury enzymes in pregnant AVP (PAVP), pregnant saline (PS), non-pregnant AVP (NAVP), and non-pregnant saline (NS) rats. Results: The PAVP group showed significantly higher systolic and diastolic blood pressure than both saline-treated groups. The weight per pup was significantly lower in the AVP-treated group than in the saline group (p<0.05). Circulating TGF-β1-3 isomer levels were significantly higher in the PAVP rats than in the NS rats. However, similar TGF-β1 and TGF-β3 levels were noted in the PS and PAVP rats, while TGF-β2 levels were significantly higher in the PAVP rats. Circulating liver-type arginase-1 and 5'-nucleotidase levels were higher in the PAVP rats than in the saline group. Conclusion: This is the first study to demonstrate higher levels of TGF-β2, arginase, and 5'-nucleotidase activity in PAVP than in PS rats. AVP may cause vasoconstriction and increase peripheral resistance and blood pressure, thereby elevating TGF-β and inducing the preeclampsia-associated inflammatory response. Future studies should explore the mechanisms through which AVP dysregulates liver injury enzymes and TGF-β in pregnant rats.

간-폐 증후군이란 진행된 간경변을 가진 환자에서 폐혈관의 확장으로 인해 동맥혈 산소 포화도가 감소하는 것을 특징으로 한다. 간경화 환자에서 동맥 산소 포화도의 감소가 보고된 이후로 간-폐 증후군은 말기 간질환을 가진 성인의 13-47% 정도에서 발생한다고 보고하고 있으나, 소아에서 발생한 국내 보고는 없다. 또한 시상하부 및 뇌하수체 기능 저하를 보이는 환자에서 비알코올성 지방간이 급격하게 간부전으로 진행되는 증례가 최근에 보고되고 있다. 저자들은 지방간을 가진 소아에서 두개인두종 절제술 후에 발생한 뇌하수체기능저하증으로 인해 간질환이 급격하게 진행하여 간-폐 증후군으로 발현된 증례를 경험하였기에 보고하는 바이다. 두부 수술 후에 시상하부 및 뇌하수체 기능 저하를 보이는 환아에서는 내분비 질환이나 대사 장애 뿐 아니라, 간질환에 대한 추적 관찰이 필요할 것이다.
