Purpose: Purposes of this study were to understand the current trends on complementary therapy in relieving chemotherapy-induced nausea and vomiting and to suggest the future research direction. Method: Subjects were selected on CINAHL, MEDLINE, Korean Academy Data Base from 1980 to 2001 which used nausea, vomiting, chemotherapy and complementary therapy as key words in experimental studies. Eight korean articles and twenty-one international articles were analyzed in terms of general characteristics, research methods, and types of complementary therapy. Data were analyzed by using descriptive statistical methods. Result: Since 2000, researchers have more actively used complementary therapy. In subject characteristics, mean age was 35.5 years old, 45% of the researchers were performed with high level of incidence of chemotherapy induced vomiting, 14% of them set limit of consecutive cycle during research, and 65% of them did not comment the selecting criteria of sample. About 60% of them were designed post-test only control group: 35% used INV by Rhodes, 31% used Likert scale, and 24% used VAS for dependent variable. Muscle relaxation therapy was mostly applied for relief of nausea and vomiting. Conclusion: Further studies will be needed to control extrinsic variables affecting nausea and vomiting in research design and to accumulate evidence with studies applying various complementary therapies.

<연구목적> HBx형질전환 생쥐에서 발생한 간세포암종의 발암과정에 종양유전자(H-rgs, c-myc)의 발현 정도를 조사하고자 하였다. <연구방법> 정상생쥐 12마리(4-18개월) 및 HBx 형질전환 생쥐 44마리(4-18개월)를 대상으로 포르말린에 고정하고 파라핀에 포매한 간 조직을 이용하여 면역조직화학적염색을 실시하였다. 실험군은 정상 부위, 이형성 부위 및 종양 부위로 구분하였으며, 종양 부위는 소결절성병변 부위와 간세 포암종 부위로 구분하였고, 이형성병변 부위는 이형성병변만 발견되는 부위, 소결절성병변과 동반된 이형성병변 부위 및 간세포암종과 동반된 이형성병변 부위로 구분하였다. <연구결과> H-rgs의 발현은 정상 간조직에 비하여 이형성병변 부위(P<0.05) 및 종양 부위(P<0.01)에서 증가하였으며, 소결절성병변 부위과 간세포암종 부위 사이에서는 간세포암종 부위에서 증가된 경향이었으나 통계학적으로 유의한 차이가 없었으며, 각 이형성병변 부위 사이에서도 유의한 차이는 없었다. c-myc의 발현은 정상 간조직 및 이형성병변 부위에 비해 종양 부위에서 증가하였으며(P<0.001), 소결절성병변 부위와 간세포암종 부위에서는 비슷하였고, 각 이형성병변부위 사이에서도 비슷하였다. <결론> HBx형질전환 생쥐에서 발생하는 간세포암종의 발생에 H-rgs는 이형성 변화를 일으키는 시기에 관여하며, c-myc은 이형성병변에서 암으로 이행하는 시기에 관여할 것으로 생각한다. Background: This experiment was designed for the expression of H-ras and c-myc in hepatocarcinogenesis of the HBx transgenic mice. Methods: Immunohistochemical stains in the paraffin embedded tissue of the liver were used for the detection of H-ras and c-myc in the 12 normal mice and 44 HBx transgenic mice of the 4-18 month old. Results: Expression of the H-ras was significantly increased in the dysplastic area (P<0.05) and tumor area (P<0.01) than in the normal liver. But there were no differences of H-ras expression between areas of microscopically identified hepatocellular carcinoma (MI-HCC) and grossly identified hepatocellular carcinoma (GI-HCC) and dysplastic areas among the only dysplastic areas, dysplastic areas with MI-HCC and GI-HCC. Expression of the c-myc was significantly increased in the tumor area (P<0.001) than in the normal liver and dysplastic area. But there were no differences of c-myc expression between areas of MI-HCC and GI-HCC, and dysplastic areas among only dysplastic areas, dysplastic areas with MI-HCC and GI-HCC. Conclusions: Our study suggests that H-ras is related to the dysplastic change and c-myc is related to the neoplastic change in the hepatocarcinogenesis of the HBx transgenic mice.

연구배경: 다양한 고형암에서 HO-1의 높은 발현이 알려져 있고, 그것의 항산화와 항세포고사의 역할로 인해 빠른 암종의 성장에 중요한 역할이 있음이 보고되고 있다. 대표적인 활성산소종 생성 항암제인 Cisplatin은 현재까지 폐암치료에 가장 광범위하게 사용되고 있으나, 여러 내성발생이 임상치료의 주요문제로 대두되고 있다. 저자들은 A549 폐암세포주에서 HO-1의 발현이 증가되었고 HO-1 활성억제제나 siRNA 방법을 통해 생존율의 의미 있는 감소와 세포고사가 유도됨을 보고한 바 있다. 이 연구의 목적은 A549 폐암세포주에 cisplatin 처리시 HO-1의 발현의 증가유무와 기전을 규명하고 실제 HO-1의 억제가 cisplatin에 의한 항암제 감수성을 증가시키는지를 알아보는데 있다. 방법: 비소세포폐암세포주인 A549, NCI-H23, NCI-H157, NCI-H460을 이용하였다. 세포독성은 MTT 방법으로 구하였고, HO-1, Nrf2, MAPK의 발현은 Western blotting으로 확인하였다. 또한 MAPK억제제들을 전처치한 후 cisplatin에 의해 유도된 Nrf2와 HO-1의 발현에 미치는 영향을 역시 Western blotting으로 관찰하였다. A549세포에 활성억제제인 ZnPP나 HO-1 small interfering RNA (siRNA)을 주입하여 cisplatin과의 병합요법시 생존율의 배가효과 유무를 MTT 방법으로 확인하였고, 이러한 효과가 ROS 형성과 HO-1의 발현변화와 관련되는지를 알아보기 위해 carboxy-H2DCFDA 방법과 Western blotting을 통해 각각 확인하였다. 결과: Cisplatin 처리시 다른 세포주에 비해 A549세포가 의의 있게 내성을 보였다. 10μM의 농도에서 시간 의존적으로 HO-1, Nrf2, MAPK의 발현이 증가하였고, MAPK 억제제들을 전 처치하였을 때 cisplatin에 의해 유도된 HO-1과 Nrf2의 발현이 억제됨을 확인하였다. HO-1의 활성억제제인 ZnPP와 HO-1 siRNA를 통해 HO-1 mRNA를 직접 억제하는 방법으로 cisplatin과 병합치료시 단독치료에 비해 의의 있는 생존율의 감소를 보였다. 이러한 효과는 활성산소종의 생성 증가와 HO-1의 발현억제에 의한 결과임을 확인하였다. 결론: Cisplatin 처리시 HO-1의 발현은 MAPK-Nrf2-HO-1의 경로를 통해 증가하였고, 부분적으로 치료에 대한 내성과 관련이 있었으며, ZnPP 등의 활성억제제나 siRNA를 통한 knock-down 방법으로 HO-1을 표적으로 억제하는 치료방법을 통해 cisplatin의 항암제 감수성을 증가시켰다. Background: Heme oxygenase-1 (HO-1) is known to modulates the cellular functions, including cell proliferation and apoptosis. It is known that a high level of HO-1 expression is found in many tumors, and HO-1 plays an important role in rapid tumor growth on account of its antioxidant and antiapoptotic effects. Cisplatin is a widely used anti-cancer agent for the treatment of lung cancer. However, the development of resistance to cisplatin is a major obstacle to its use in clinical treatment. We previously demonstrated that inhibiting HO-1 expression through the transcriptional activation of Nrf2 induces apoptosis in A549 cells. The aim of this study was to determine of the inhibiting HO-1 enhance the chemosensitivity of A549 cells to cisplatin. Materials and Methods: The human lung cancer cell line, A549, was treated cisplatin, and the cell viability was measured by a MTT assay. The change in HO-1, Nrf2, and MAPK expression after the cisplatin treatment was examined by Western blotting. HO-1 inhibition was suppressed by ZnPP, which is a specific pharmacologic inhibitor of HO activity, and small interfering RNA (siRNA). Flow cytometry analysis and Western blot were performed in to determine the level of apoptosis. The level of hydrogen peroxide (H2O2) generation was monitored fluoimetrically using 2`,7`-dichlorofluorescein diacetate. Results: The A549 cells showed more resistance to the cisplatin treatment than the other cell lines examined, whereas cisplatin increased the expression of HO-1 and Nrf2, as well as the phosphorylation of MAPK in a time-dependent fashion. Inhibitors of the MAPK pathway blocked the induction of HO-1 and Nrf2 by the cisplatin treatment in A549 cells. In addition, the cisplatin-treated A549 cells transfected with dither the HO-1 small interfering RNA (siRNA) or ZnPP, specific HO-1 inhibitor, showed in a more significantly decrease in viability than the cisplatin-only-treated group. The combination treatment of ZnPP and cisplatin caused in a marked increase in the ROS generation and a decrease in the HO-1 expression. Conclusion: Cisplatin increases the expression of HO-1, probably through the MAPK-Nrf2 pathway, and the inhibition of HO-1 enhances the chemosensitivity of A549 cells to cisplatin.

Background: In aged skin, degradation of collagen fibers, which occupy the majority of the extracellularmatrix in the dermis, and changes of aquaporin 3 (AQP3) and skin constituents, such as hyaluronic acidand ceramide, cause wrinkles and decrease skin moisturization to contribute to dryness and lowerelasticity skin. Red ginseng (RG) is used as a cosmetic and food material and is known to protect fromUVB-induced cell death, increase skin hydration, prevent wrinkles, and have an antioxidative effect. But,in general, RG used as a material is the soluble liquid portion in the solvent, and the part that is notsoluble in the solvent is discarded. Thus, we made the whole RG into microgranulation and dispersed inwater to produce gel form for using entire RG, and it was named red ginseng NaturalGEL (RG NGEL). Methods: RG NGEL was investigated for matrix metalloproteinases inhibitory activity, induction of Type Icollagen, AQP3, hyaluronan synthetase 2, serine palmitoyl transferase, ceramide synthase 3, and filaggrinexpression and compared with RG water extract. Results: RG NGEL reduced the levels of UV-induced matrix metalloproteinases and increased Type Icollagen in human fibroblast cells and upregulated AQP3, hyaluronan synthetase 2, serine palmitoyltransferase, ceramide synthase 3, and filaggrin expressions in human keratinocytes compared with RGwater extract. Conclusion: RG NGEL has the potential as an effective reagent for antiaging cosmetics to improve wrinkleformation and skin hydration.
