The aim of this study was to determine and compare the preventive effect of Korean White Ginseng and Red Ginseng on oxidative stress in H₂O₂-treated HepG2 cells. The roots of ginseng were extracted with 70% methanol and partitioned with butanol to obtain saponin fractions, which have been known as bioactive constituents of ginseng. 2′,7′-Dichlorofluorescein diacetate (DCF-DA) assay and malondialdehyde (MDA) content were measured for evaluating intracellular reactive oxygen species (ROS) generation. Also, mRNA expressions and activities of antioxidant enzymes were analyzed to determine the antioxidant activity of saponin or non-saponin fractions of ginsengs. According to DCF-DA assay, H₂O₂-induced MDA release and ROS generation were significantly reduced by treatment with saponin fractions of white and red ginseng roots. Also, saponin fractions increased effectively intracellular antioxidant enzyme activities including catalase, glutathione peroxidase and superoxide dismutase in H₂O₂-treated HepG2 hepatoma cells. In general, red ginseng was more effective than white ginseng for reducing oxidative stress. These results indicate that administration of red ginseng may certainly contribute relatively stronger than white ginseng to prevent from damaging liver function by oxidative stress.

Recently biodiesel has drawn much attraction as renewable enegy due to its environmental benefits and the fact that it is made from renewable resources. However, the production cost of biodiesel is one of the main hurdle to commercialize it. One of the way to reduce the biodiesel production cost is to use the waste cooking oil as feedstock. In the conventional transesterification process of waste cooking oils for biodiesel production, the presence of free fatty acids and water causes severe problems such as formation of soap and decreasing of catalyst yield. Much effort has been devoted to solve the above problems and one of the promising way is the supercritical methanol treatment which is performed at the methanol supercritical environment (>239.45oC, >8.10 Mpa)one of the serious problems of the application of SCM process for the biodiesel production is the tough operation condition(high pressure, high temperature. In this study, we have studied about the supercritical methanol treatment for the biodiesel production with the soybean waste cooking oil as a feedstock in the present of various heterogeneous solid catalysts such as mesoporous silica and acid-doped mesorpous silica. Biodiesel conversion was increased at more mild opreation condition to the previous studies by using the catalysts. The conversion was more enhanced by modifying the catalysts.

A single residue analytical method was developed for herbicide chlorpropham in various crops. Brown rice, apple, mandarin, Kimchi cabbage, green pepper, potato, and soybean were selected as representative crops, and clean-up system, partition solvent, and extraction solvent were optimized. For high performance liquid chromatography (HPLC), $C_{18}$ column was used with elution solvents of water and acetonitrile. Limit of quantitation (LOQ) of chlorpropham was 2 ng (S/N >20), and excellent linearity ($R^2$=1.000) was achieved. Method limit of quantitation (MLOQ) was 0.02 mg/kg. For recovery tests, crop samples were macerated and fortified with chlorpropham standard solution at three fortification levels (MLOQ, 10 MLOQ, and 100 MLOQ). And then those were extracted with acetonitrile, concentrated and partitioned with n-hexane. The n-hexane layer was then concentrated, cleaned-up through Florisil$^{(R)}$ column with ethyl acetate:n-hexane (5:95, v/v) prior to concentration and analysis with HPLC. Good recoveries from 76.8 to 107.9% with coefficients of variation of less than 10% were obtained, regardless of sample type, which satisfies the criteria of Korea Food and Drug Administration. Those results were confirmed with liquid chromatography-mass spectrometry (LC-MS). The method established in this study could be applied to most of crops as an official and general method for the analysis of chlorpropham residue.

Purpose: This study aimed to determine the clinical and pathological factors associated with a higher rate of positive or close margins after breast-conserving surgery (BCS) by comparing these patients to patients with a negative margin. The second aim was to evaluate intraoperative resection margin status and reoperation rates for margin control in patients who underwent BCS. Methods: We reviewed the clinical and pathological data of all women diagnosed with invasive breast carcinoma (IBC) and ductal carcinoma in situ (DCIS) at our institution between January 2006 and December 2016. Results: During the 10-year study period, 785 patients were diagnosed with either IBC or DCIS, and 402 of these patients had undergone a total mastectomy as the primary treatment. The remaining 383 patients who underwent BCS were included in the final analysis. Of these, 100 patients (26.1%) had intraoperative positive or close margins. The remaining 283 patients (73.9%) had a negative margin intraoperatively, but 32 of these patients had positive or close margins on permanent sections. In the multivariate analyses, microcalcifications on mammograms (vs. none; odds ratio [OR], 1.911; 95% confidence interval [CI], 1.156–3.160), in situ carcinomas larger than 2.0 cm (vs. ≤2.0 cm; OR, 3.106; 95% CI, 1.193–8.086), and lumpectomy (vs. quadrantectomy; OR, 2.863; 95% CI, 1.268–6.622) showed a significant association with a positive or close surgical margins. Patients with intraoperative positive or close margins underwent more reoperation than those with negative margins (5.0% vs. 2.8%). Conclusion: After BCS, microcalcifications on mammograms, large-sized in situ carcinomas, and lumpectomy were more likely to have positive or close margins.
