        This study aimed to examine the effect of a mild elevation in serum cholesterol level in a porcine coronary overstretch restenosis model using a balloon angioplasty catheter or drug-eluting coronary stent. Pigs were divided into two groups and were fed a commercial normal diet (CND, n = 4) or a high-fat diet (HFD, n = 4) for 5 weeks. Coronary overstretch injury by balloon angioplasty or stent implantation was induced in the left anterior descending and left circumflex artery after 1 week of feeding. Histopathological analysis was performed at 4 weeks after coronary injury. During the experiment, the total cholesterol level in the HFD group increased by approximately 44.9% (from 65.9 ± 3.21 mg/dL at baseline to 95.5 ± 9.94 mg/dL at 5 weeks). The lumen area in the CND group was reduced in comparison with that in the HFD group after balloon angioplasty. After stent implantation, the injury score showed no significant difference. There were significant differences in the neointimal area (2.7 ± 0.33 mm2 in the CND group vs. 3.3 ± 0.34 mm2 in the HFD group, p<0.05), lumen area (2.6 ± 0.54 mm2 in the CND group vs. 2.0 ± 0.33 mm2 in the HFD group, p<0.05), and percent area stenosis (52.0 ± 7.96% in the CND group vs. 62.4 ± 5.15% in the HFD group, p<0.05). Body weight change was not different between the two groups. Increased serum cholesterol level activated vascular smooth muscle cell proliferation in the porcine coronary overstretch model.

        The spotted wing drosophila(Drosophila suzukii)is one of the serious fruit pest that has a wide range of fruit crops like blueberries, cherries and grapes. It came up the larvae cause dagmage by feeding on the pulp inside fruits and berries and spotted wing drosophila also has a adversely affect export to Austrailia and New zealand as a quarantine pest. This study conduct to survey occurrence of drosophila spp. from 2016 to 2018 on harvest period of grapevine in vinyard of Okcheon ,Yeongdong and fruit packing place for export to New zealand and USA. Vinegar and wine mixture was used to attract fruits flies. We also investigated to what color is the best stimulus to catch a vinegar flies. Our result shows that significant differences were observed in total flies trapped in red and black colors. This study will contribute to future research for monitoring and control drosophilid flies.
