Hemophagocytic syndrome(HPS) has four subgroup, sporadic disorder, associated with acute infection, familial form seen in children, and associated with malignant disorders, immunodeficiencies, defective leukocyte function. Histologically, Hemopoietic cells are actively ingested by moncytes/macrophages in various organs, including lymph nodes, bone marrow, liver, and spleen. Epstein-Barr virus(EBV) is now thought to be one of the major causes for the virus-associated hemophagocytic syndrome(VAHS). Epstein-Barr(EB) virus infection is common, with up to 90% of individuals demonstrating positive titiers by age 20. Although elevated liver function tests commonly occur, severe hepatitis is rare. Only seven cases of ascites complicating Epstein-Barr infection are reported, but none clearly demonstrate the abscence of other causes of hepatic dysfunction. We are reporting a case of Epstein-Barr Virus-associated hemophagocytic syndrome with ascites.

SKT is consisted of skullcap radix, knope-sedge radix and trametes mushroom. SKT mixture extract has been used for curing breast cancer and cervical cancer as a folk medicine without any kind of experimental evidence to support the rationales for its clinical use. This study was undertaken to investigate the antitumor effects and toxicity of SKT. Tumor was induced by implantation of B16F10 melanoma cells $(1{\times}10^6\;cells/mouse)$ into abdominal skin in ICR mice and SKT application (5 mg/mouse, p.o.) was initiated 4 days prior to tumor induction and lasted for 42 days. SKT significantly inhibited not only tumor growth but also metastasis of i.v. implanted melanoma cells into lung and showed prolonged life span of tumor bearing mice. The combined theraphy of SKT with doxorubicin was more effective against tumor metastasis into lung. SKT almostly recovered serum SGPT to normal level of galactosamine/LPS-induced hepatitis mice. High dose of SKT did not show any acute side effects. But, in vitro SKT did not inhibit the growth of melanoma cells, which suggests that the antitumor effects of SKT might be menifested by indirect mechanisms.

Sayuksan has been widely applied to treat a variety of diseases such as acute hepatitis, gastritis, and colitis. Sayuksan consists of medicinal herbs such as Glycrrhizae uralensis Fischer, Paeonia lactiflora Pallas, Bupleurum falcatum Linne, and Poncirus trifoliata Rafinesqul. Methanol extracts (1 mg/mL) from the four kinds of medicinal herbs did not show antibiotic activities against general test strains and multi-drug resistant strains. The antibacterial activity of fermented medicinal herbs extracts with Lactobacillus spp. strain was confirmed as Gram-positive bacteria which are higher than Gram-negative bacteria. Extracts of Glycrrhizae uralensis Fischer fermented with Lb. casei KCTC 3109 displayed inhibitory diameters of 16 mm against Pseudomonas aeruginosa P01828. Superoxide dismutase (SOD)-like activity of the medicinal herb extracts was not determined, but the extract of Paeonia lactiflora Pallas fermented with six strains of Lactobacillus spp. had the highest antioxidant activity. SOD-like activity of Paeonia lactiflora Pallas extracts fermented by Lb. brevis KCTC 3498 was $41.4{\pm}0.8%$, which was the highest antioxidant activity among the fermented extracts with the other medicinal herbs.

Biphenyl dimethyl dicarboxylate (DDB) has been used for the treatment of acute and chronic hepatitis. However, its poor solubility in water, $2.5\;{\mu}g/ml$, caused low bioavailability of the drug after its oral administration. In order to increase the dissolution of DDB in gastrointestinal tracts, consequently to increase the bioavailability of the drug, DDB tablet was prepared with solid dispersion of DDB with poloxamer 338 or 407 using a direct compression method. To improve the flowability of the solid dispersion, Aerosil was used as an adsorbent. The effect of formulation variables (poloxamer and Aerosil contents) on the dissolution rate of DDB from tablets was investigated using an analysis of variance. The dissolution rate of DDB from tablets was evaluated with KP II (paddle) method. The dissolution patterns of the drug from the tablet prepared with poloxamer 407 were affected significantly by the contents of poloxamers and Aerosil over the range employed, but those of the drug from the tablet prepared with poloxamer 338 were not. The optimum formulation of the DDB tablet, showed the same dissolution pattern as that of the reference, was obtained after polynomial equations of drug dissolution profiles for each formula were fitted to contour plots. The optimum formulation ratios of DDB:poloxamer 407:Aerosil were 1:2.5:2.5 and 1:5:5.

Cryoglobulinemia is the presence of globulins in the serum that precipitate on exposure to cold temperatures(cryoglobulins). Pulmonary complications of cryoglobulinemia include interstial infiltration, impaired gas exchange, small airway disease and pleurisy. Only one other acute respiratory distress syndrome(ARDS) case has been described in patients with cryoglobulinemia. A 55-years old man was admitted with dyspnea. He had been diagnosed as being a hepatitis B virus antigen carrier 15 years ago. On the first admission, chest radiography showed a bilateral pleural effusion and a patchy infiltration on both lungs. On protein- and immuno-electrophoresis, cryoglobulinemia was confirmed. The patient was treated with corticosteroid and plasmapheresis. Forty-five days after the diagnosis, the patient complained of progressive dyspnea and showed a diffuse bilateral pulmonary infiltration on chest radiography. Despite intensive care with mechanical ventilation, the patient died as consequence of hypoxemia and multiple systemic organ failure. On a pathologic examination of the postmortem lung biopsy, multiple necrotizing vasculitis and increased infiltration of the lymphocytes and monocytes were observed. In conclusion, ARDS developed as a result of pulmonary hemorrhage due to cryoglobulinemia-associated vasculitis.

Chronic infection by hepatitis B virus (HBV) greatly increases the risk for liver cirrhosis and hepatocellular carcinoma (HCC). The outcome of HBV infection is shaped by the complex interplay of the mode of transmission, host genetic factors, viral genotype, adaptive mutations, and environmental factors. The pregenomic RNA transcription of HBV for their replication is regulated by the core promoter activation. Core promoter mutations have been the reason for acute liver failure and are associated with HCC development. We obtained HBV genes from a patient in Myanmar who was infected with HBV and identified gene variations in the core promoter region. For measuring the relative transactivation activity of the core promoter, we prepared the core-promoter reporter construct. Among the gene variations of the core promoter, the mutations of C1731T and G1806A were associated with increase in the transactivation of the HBV core promoter. Through computer analysis for searching for a tentative transcription factor binding site, we showed that the mutations of C1713T and G1806A newly created C/EBPβ and XBP1-responsive elements of the core promoter, respectively. The ectopic expression of C/EBPβ largely increased the HBV core promoter containing the C1713T mutation and that of XBP1 activated the M95 promoter containing the G1806A mutation. Our efforts to treat and prevent HBV infections are hampered by the emergence of drug-resistant mutations and vaccine-escape mutations. Our results provide the biological properties and clinical significance of specific HBV core promoter mutations.

This study aimed to examine the safety of HemoHIM, a dietary supplement containing methoxsalen. HemoHIM is a dietary supplement marketed globally, and a competitor to ginseng. It has been reported to contain methoxsalen, a plant extract for treating psoriasis and vitiligo. Methoxsalen is known to cause hepatotoxicity, but most of the cases has been reported from ingestion as a drug, not a food. There are no reports of hepatotoxicity from the consumption derived from natural products such as Angelica gigas, Cnidium officinale, and Paeonia lactiflora, which are the main ingredients in the HemoHIM. However, a recent case of acute hepatitis was reported in Hong-Kong after ingestion of HemoHIM. It is difficult to conclude that hepatitis was caused by HemoHIM, because there was no check of co-occurring medications with a higher risk of hepatotoxicity, no description of the progress, no quantitative comparison of methoxsalen in HemoHIM to it in common foods such as carrots and celery, and no description of the patient's underlying diseases. On the other hand, there was a study that suggest hemoHIM is safe, and that study had adequate number of subjects even though more studies are needed to ensure safety.

Transfusion related acute lung injury (TRALI) is a serious, potentially life-threatening complication of transfusion therapy that is sometimes under diagnosed and under reported. Patients with TRALI present with dyspnea/respiratory distress and fever. The symptoms, signs and chest radiological findings in TRALI are similar to transfusion associated circulatory overload, which makes it is difficult to distinguish it from circulatory overload. Although the mortality rate in cases of TRALI is relatively low, TRALI is the third most common cause of fatal transfusion reactions next to ABO blood type incompatibility and hepatitis. Mild-to-moderate cases of TRALI may be misdiagnosed as volume overload. Recently, we encountered two cases where the patients suffered from dyspnea and fever after a transfusion. and review of the relevant literature.

Objectives: The purpose of this study is to investigate safety of postpartum herbal medicine by assessing the effect of taking herbal medicine of postpartum period on liver function. Methods: A retrospective chart review was conducted on 167 mothers who underwent liver function tests (LFT) within 3 months before and after childbirth among mothers who gave birth at ○○ Hospital between January 1, 2016 and May 31, 2018. Mothers with abnormally elevated LFT during pregnancy were excluded. Among 167 women, 6 women are herbal-medicine-group took herbal medicine for 5-6 weeks during postpartum period, and 161 patients are general -group who did not take herbal medicine. LFT Variation of Subjects before and after childbirth were compared between the two groups. And subjects who had elevated liver levels above the normal range after delivery were classified separately, the characteristics and causes of changes in liver levels were analyzed, and the presence or absence of drug-induced liver damage was confirmed. Results: Among a total of 167 subjects, there were 5 women in the herbal-medicine-group and 150 women in the general-group who had changes in liver values within the normal range after childbirth. Aspartate transaminase (AST) change before and after childbirth in the herbal-medicine-group was 3.40±1.82, and AST change in the general-group was 2.92±8.59, showing no significant difference between the two groups (p=0.901). Increase of Alanine transaminase (ALT) before and after childbirth in the herbal-medicine-group was 5.60±3.65, and ALT change in the general-group was 8.01±11.81, showing no significant difference between the two groups (p=0.651). There were 12 subjects who had elevated AST, ALT above the normal range after delivery, including 1 in the herbal-medicine-group and 11 in the normal mothers group. Valuation of 1 Subject of the herbal-medicine-group before and after delivery was 17 IU/L of AST and 52 IU/L of ALT. Because results of AST, ALT is under the standard to diagnose to liver damage, she was observed without any treatment. However the cause of AST, ALT elevation was not found in the chart, she was receiving treatment for diabetes and hyperlipidemia. The general-group had an average increase of AST 35.64±22.67 IU/L and ALT 53.00±26.80 IU/L. As a result of analyzing the cause, there were direct causes such as autoimmune hepatitis, chronic hepatitis B, and acute pyelonephritis. Abnormal elevations in liver levels were also found in mothers with hypothyroidism, diabetes, and fever of unknown cause, although they were not direct causes. Conclusions: To investigate the safety of taking herbal medicines, we assess the variation in AST and ALT within 3 months before and after delivery in the herbal-medicine-group and general-group. There was no significant difference between two groups.

Background: Infection with hepatitis B virus (HBV) is a major global public health problem, with a wide spectrum of clinical manifestations. Human cytosolic glutathione-S-transferases (GSTs) include several classes such as alpha (A), mu (M), pi (P), sigma (S), zeta (Z), omega (O) and theta (T). The present study aimed to investigate the role of GST omega genes (GSTO1 and GSTO2) in different groups of patients infected with HBV. Materials and Methods: HBV groups were classified according to clinical history, serological tests and histological analysis into normal carriers (N), acute (A), chronic (CH), cirrhosis (CI) and hepatocellular carcinoma (HCC) cases. The study focused on determination of the genotypes of GST omega genes (GSTO1 and GSTO2) and GST activity and liver function tests. Results: The results showed that GSTO1 (A/A) was decreased in N, A, CH, CI and HCC groups compared to the C-group, while, GSTO1 (C/A) and GSTO1(C/C) genotypes were increased significantly in N, A, CH, CI and HCC groups. GSTO2 (A/A) was decreased in all studied groups as compared to the C-group but GSTO2(A/G) and GSTO2(G/G) genotypes were increased significantly. In addition, GST activities, albumin and TP levels were decreased in all studied groups compared to the C-group, while the activities of transaminases were increased to differing degrees. Conclusions: The results indicate that GSTO genetic polymorphisms may be considered as biomarkers for determining and predicting the progression of HBV infection.
