  • Objectives : This study was performed to investigate the anti-fibrogenic effect of greater celandine on cultured rat hepatic stellate cells. Materials and Methods : Hepatic stellate cells (HSC-T6) were treated with various concentrations of greater celandine extract for 24, 48, and 72 hours. The extraction was done with distilled water. After the treatment, cell viability, proliferation, mRNA of the ${\alpha}SMA$, TIMP-1, TIMP-2, collagen I ${\alpha}$ 1, MMP-2, IL-6, TGF-${\beta}1$, PDGFr-${\beta}1$, Bcl-2, Bax, Bcl-xl, caspase-3, caspase-9 and the activities of SOD and catalase were measured by using MTT assay, BrdU assay, real-time PCR, superoxide dismutase assay and catalase assay. Results : The viability, proliferation, mRNA expression and synthesis of collagen of the hepatic stellate cells were inhibited as the concentration increased, which indicates the herb has an inhibitory effect on fibrogenesis of the liver by regulating the fibrosis associated genes in transcription. Conclusions : These results suggest that greater celandine would be beneficial in the treatment of fibrotic patients as well as for patients with chronic hepatitis.

  • Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease characterized by hepatic fat accumulation, while nonalcoholic steatohepatitis (NASH) is an advanced form of NAFLD characterized by hepatic inflammation, fibrosis, and liver injury, resulting in liver cirrhosis and hepatocellular carcinoma (HCC). Given the evidence that ginseng and its major bioactive components, ginsenosides, have potent anti-adipogenic, anti-inflammatory, anti-oxidative, and anti-fibrogenic effects, the pharmacological effect of ginseng and ginsenosides on NAFLD and NASH is noteworthy. Furthermore, numerous studies have successfully demonstrated the protective effect of ginseng on these diseases, as well as the underlying mechanisms in animal disease models and cells, such as hepatocytes and macrophages. This review discusses recent studies that explore the pharmacological roles of ginseng and ginsenosides in NAFLD and NASH and highlights their potential as agents to prevent and treat NAFLD, NASH, and liver diseases caused by hepatic steatosis and inflammation.

  • 신장섬유화는 내 외부적인 요인들에 의해 발생하며, 그 요인들에 의해 염증이 생기고 지속적인 손상이 일어날 경우 신기능의 상실이 유발된다. 또한 신장섬유화는 세포 외 기질의 과다축적, TGF-${\beta}$나, TNF-${\alpha}$, IL-1과 같은 사이 토카인에 의해 발생하며, TGF-${\beta}$는 신장 섬유화의 과정과 Type I collagen과 fibronectin, PAI-1을 포함한 섬유화 관련 인자들의 발현 유도에 중요한 역할을 한다. 본 연구에서는 TGF-${\beta}$를 처리한 신장섬유화 유도 모델에서 Moringa oleifera Lam 추출물에 대한 섬유화 관련 인자들의 영향을 확인하였다. 실험 결과 TGF-${\beta}$로 유도된 신장 섬유화 세포에서 모링가 추출물이 fibronectin, Type I collagen과 PAI-1의 단백질 및 mRNA 발현을 저해하였으며, 모링가 추출물 중 모링가 뿌리추출물이 가장 영향이 있는 것으로 확인 되었다. 모링가 뿌리추출물이 어떠한 기전을 통하여 섬유화 관련 인자들의 발현을 조절하는지 알아보기 위한 TGF-${\beta}$로 유도된 $T{\beta}RII$ 및 그 하위 기전의 인산화 정도를 확인한 실험에서 모링가 뿌리추출물이 TGF-${\beta}$로 유도된 $T{\beta}RII$과 그 하위기전의 Smad4, ERK의 인산화를 저해하였다. 그러나 TGF-${\beta}$에 의해 유도된 JNK와 p38, PI3K/AKT의 인산화에는 영향이 없었다. 따라서 모링가 뿌리추출물이 TGF-${\beta}$로 유도된 신장 섬유아세포에서 $T{\beta}RII$와 그 하위 기전인 Smad4, ERK를 통해서 Type I collagen 과 fibronectin, PAI-1의 발현을 조절하여 섬유화를 저해 한다는 것을 예상할 수 있다. 결론적으로 모링가 뿌리추출물이 섬유화 치료 및 완화에 좋은 물질이 될 수 있을 것으로 생각된다.

  • A 65-year-old woman was admitted due to poor oral intake and a dry cough over the previous 3 months. The physical examination was remarkable for bibasilar crackles, and plain chest radiography showed reticulation in both lower lung fields. A pulmonary function test demonstrated a restrictive pattern with a reduced diffusing capacity of the lung for carbon monoxide. High resolution computed tomography showed reticulation and honey-combing in both peripheral lung zones, which was consistent with usual interstitial pneumonia pattern. Her skin showed livedo reticularis. The erythrocyte sedimentation rate and C-reactive protein level were elevated, and hematuria was noted on urinary analysis. A serologic test for auto-antibodies showed seropositivity for Myeloperoxidase-Anti-neutrophil cytoplasmic antibody (MPO-ANCA). A kidney biopsy was performed and showed focal segmental glomerulosclerosis. She was diagnosed as having pulmonary fibrosis with microscopic polyangiitis (MPA) and treated with high dose steroids. Here we report a case of pulmonary fibrosis coexistent with microscopic polyangiitis.

  • Hepatic disease has been noted and reported for involvement various detrimental factors. Among many detrimental injury factors, alcohol has been noted for hepatitis, fatty liver, fibrosis, and hepatic cirrhosis. The purpose of this study is to develop animal model for hepatic fibrosis in pig with ethanol, and to search new anti-fibrogenic agent. Twelve male Landrace pigs were divided into 3 groups of 4 animals each. Group 1, 2 and 3 were fed with ceramic water only, ceramic water + liquid diet containing 20% ethanol and normal tap water + containing 20% ethanol for 12 weeks, respectively. At week 12, all pigs were immediately sacrificed for collection each tissue and blood. Serologically, serum ALT and AST levels were significantly reversed in group 2, comparing to group 3. They were normal range in pigs of group 1. Microscopically, macrovesicular lipid droplets and moderate necrosis were evident in the tap water + ethanol fed group 3. However, ceramic water intake group 1 showed normal. Moreover, in group 3, little fatty changes and mild necrosis were observed. Collagen fibers were detected in the spaces of surrounding periportal and interlobular areas in the group 3 of tap water + ethanol, but collagen synthesis and its thickness of fibrotic septa connecting portal tracts was markedly reduced in the group 2 of ceramic water + ethanol. In immunohistochemistry, myofibroblasts were detected in the ethanol and tap water treated group 3. No or a few myofibroblasts were observed in groups 1 and 2. CYP 2E1 was rarely detected in group 1 fed ceramic water. However, group 2 showed slightly activation of CYP 2E1 in the area of pericentral, while CYP 2E1 was significantly activated in group 3 fed tap and ethanol. Taken together above, alcohol fibrosis model in pig was established. Furthermore, ceramic water had an inhibitory and protecting ability for alcohol-induced hepatic damages.

  • Background and Objectives: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease mainly affecting young women of childbearing age. SLE affects the skin, joints, muscles, kidneys, lungs, and heart. Cardiovascular complications are common causes of death in patients with SLE. However, the complexity of the cardiovascular system and the rarity of SLE make it difficult to investigate these morbidities. Patient-derived induced pluripotent stem cells (iPSCs) serve as a novel tool for drug screening and pathophysiological studies in the absence of patient samples. Methods and Results: We differentiated CMs from HC- and SLE-iPSCs using 2D culture platforms. SLE-CMs showed decreased proliferation and increased levels of fibrosis and hypertrophy marker expression; however, HC-and SLE-monolayer CMs reacted differently to SLE serum treatment. HC-iPSCs were also differentiated into CMs using 3D spheroid culture and anti-Ro autoantibody was treated along with SLE serum. 3D-HC-CMs generated more mature CMs compared to the CMs generated using 2D culture. The treatment of anti-Ro autoantibody rapidly increased the gene expression of fibrosis, hypertrophy, and apoptosis markers, and altered the calcium signaling in the CMs. Conclusions: iPSC derived cardiomyocytes with patient-derived serum, and anti-Ro antibody treatment could serve in effective autoimmune disease modeling including SLE. We believe that the present study might briefly provide possibilities on the application of a combination of patient-derived materials and iPSCs in disease modeling of autoimmune diseases.

  • It has been reported that antisynthetase syndrome belongs to the idiopathic myositis group which includes pulmonary interstitial disease, arthritis, Raynaud's phenomenon, and mechanic's hand, associated with the anti-Jo1 antibody. A 60- year-old man presented with one month history of lower limbs weakness, rapidly progressive exertional dyspnea, and arthralgia. A markedly increased titers of anti-Jo1 antibodies were found. Chest CT showed idiopathic pulmonary fibrosis. Muscle biopsies were consistent with polymyositis. A high dose corticosteroids and cyclosporine were not effective. We report a case of antisynthetase syndrome, in which immunosuppressive agents could not rescue the deteriorating disease course.
