In cases of anterior crossbite patients, there are many problems. They are dissatisfied with facial appearance and in difficulties for speaking, and sometimes are related to reduced vertical dimension. Vertical dimension is defined distances between two points which one is on maxilla and the other is on mandible. Loss of vertical dimension may causes temporomandibular disorder, loss of masticatory function, and collapse of occlusion. This is a clinical study of 50 years old male with reduced vertical dimension and anterior-crossbite. We treated patient with fixed bridge and conventional removable partial denture, and then the activity of masseter and temporalis muscle were recorded and analyzed by means of Biopak?? system(Bioresearch Inc., Millwakee Wisconsin). The result was satisfactory functionally and esthetically.

Aims: This study aimed to investigate hepatitis B virus (HBV) reactivation among hepatitis C virus (HCV) infected patients treated with oral direct acting antiviral (DAA) therapy in areas endemic for HBV in Korea. Methods: A total of 821 HCV-infected patients receiving oral DAA therapy from March 2015 to November 2016 were evaluated. Serum HBV DNA and HCV RNA was regularly assessed during and after DAA treatment in patients with HBV-HCV coinfection. HBV virological reactivation was defined as a >1 log increase in HBV DNA from baseline or a reappearance of HBV DNA for those with baseline undetectable HBV DNA. Clinical reactivation was defined as a serum alanine aminotransferase level ≥3-fold over the upper limit of normal or > 100 U/L. Results: Prior to DAA therapy 95.8% (787/821) had HBsAg testing and 1.7% (13/787) were positive. HBV virological reactivation was found in 7 (53.8%) of the 13 patients. HBV-related clinical reactivation was not observed in our cohort. Conclusions: For HBV-HCV co-infected patients, the risk of HBV virological reactivation was present after oral DAA treatment for HCV infection. Monitoring the HBV DNA level during oral DAA therapy for HCV infection is warranted.

Field survey were conducted in to evaluate the insect damage to growing Lemonbalm(Melissa officinalis). Lemaonbalm, belonging to the Lamiaceae family, is a smelling perennial shurb which is possible to grow in Korea. To date, there has been minimal research regarding plant culture, pest insect occurrence and management research about herbal plants in Korea. Meanwhile, it grows for processed food and cosmetics in Jellabukdo, and necessity to pest management is on the rise. Chrysolina exanthematica(Coleoptera: Chrysomelidae) was realized not pest but general insect in Korea. But, in this survey, it is found to pest about lemonbalm. Damage period was concentrated in April. Rest period was decreased in density. At size of Chrysolina exanthematica, larva is 7.0*3.6mm, pupa is 8.3*5.3mm, and adult is 9.7*6.7mm. In farm surveying about Chrysolina exanthematica host preference of 5 species herb plants, Lemonbalm has great preference but, Oregano has no preference. Surveying leaf damage about 6 species in Lamiaceae family in lab., Lemonbalm belonging to Melissa genus has great damage, Some species in Mentha genus have little damage. And, Oregano in Origanum genus no damage. In Growth characteristics of healthy and damage plant, plant length on damage plant is decreased 41.3%, number of tiller is decreased 67%. Fresh and dry plant weight of damaged plant is decreased 66.7%, 64.2% compared with healthy plant. Because damage of insect can influence on plant main contitutents, we analysed the constitutent parts of extracts from supercritical fluid extraction system using gas chromatography/mass spectrometer.
