  • 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.

  • B형간염바이러스(HBV)의 만성 감염은 간경화와 간세포암 발생 빈도를 현저히 높인다. HBV 감염의 임상적 결과는 숙주 유전적 요인과 바이러스의 유전자 변이, 그리고 환경적 요인 등에 결정된다. HBV 복제를 위한 HBV의 pre-genomic RNA 전사는 바이러스의 core promoter 활성화에 의해 조절된다. Core promoter 돌연변이는 급성간 질환과 간세포암 발생에 연관되어 있다. 본 연구팀은 미얀마의 HBV 감염 환자들로부터 바이러스 유전자를 획득하여 core promoter 부위의 유전자 변이들을 파악하였다. Core promoter의 상대적 유전자 활성 차이를 분석하기 위해서 core promoter를 luciferase reporter에 재조합한 시스템을 제작하였다. 분석한 core promoter의 유전자 변이들 중에서 C1731T와 G1806A 돌연변이가 HBV core promoter의 전사 활성화를 증가에 관여하였다. 돌연변이 부위를 중심으로 전사 인자들의 가능한 결합 부위 변화를 컴퓨터 프로그램 분석을 통해 조사한 결과, C/EBPβ와 XBP1 반응 부위가 새롭게 생성되었음을 도출하였다. C/EBPβ의 세포 내 발현은 C1713T 돌연변이를 가진 core promoter의 전사 활성을 증가시켰으며, XBP1 발현은 G1806A 돌연변이를 함유한 M95 promoter를 활성을 증가시켰다. HBV 감염의 치료는 약제 내성과 백신 회피 돌연변이 발생으로 문제점을 가지고 있는 상황에서, 이 연구 결과는 HBV core promoter 돌연변이의 분자생물학적 그리고 임상학적 중요성을 제공한다.

  • 이 연구는 메톡살렌이 함유된 건강 보조 식품인 헤모힘의 안전성을 조사하는 것을 목표로 했다. 헤모힘은 전 세계적으로 판매되는 건강 보조 식품으로 인삼과 경쟁 관계에 있는 제품이다. 건선 및 백반증 치료용 식물 추출물인 메톡살렌이 함유되어 있는 것으로 보고되었다. 메톡살렌은 간독성을 유발하는 것으로 알려져 있지만, 대부분의 사례는 식품이 아닌 의약품으로 섭취했을 때 발생한 것으로 보고되었다. 헤모힘의 주원료인 당귀, 천궁, 백년초 등 천연물에서 추출한 성분의 섭취로 인한 간독성 보고는 아직 없다. 그러나 최근 홍콩에서 헤모힘 섭취 후 급성 간염이 발생한 사례가 보고되었다. 간독성 위험이 높은 약물을 함께 복용했는지 확인되지 않았고, 경과에 대한 설명이 없으며, 당근, 셀러리 등 일반 식품에 함유된 메톡살렌과 헤모힘의 메톡살렌을 정량적으로 비교하지 않았으며, 환자의 기저 질환에 대한 설명이 없어 헤모힘으로 인한 간염이라고 단정하기는 어렵다. 반면에 피험자 수가 충분하였던 헤모힘이 안전하다는 연구도 있다. 안정성을 주장하려면 더 많은 연구 논문이 필요하다고 생각된다.

  • 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.
