Objective : to investigate the modalities and treatments with atopic dermatitis. Methods : We made up a questionnaire consisting of symptoms, birth, family history, previous treatments of atopic dermatitis. We interviewed mild to severe 60 atopic dermatitis patients with questionnaire, from August to October, 2008 who were participating in clinical trials of Kyunghee University East-west neo medical center. Results : The results obtained are summarized as follows: 1. 49(81.7%) out of 60 patients reported previous or current use of medical treatment, and most common type of medical treatment was topical corticosteroid (95.9%). Oral antihistamine (61.2%), oral corticosteroid (61.2%) were also commonly used. 2. 31(51.7%) out of 60 patients reported previous or current use of oriental medical treatment, and most common type of oriental medical treatment was herbal medicine(100%). Acupuncture (41.9%), Herbal external supplements (22.6%) were also used. 3. 36(60.11% ) out of 60 patients reported previous or current use of folk remedies, and the most common type of folk remedy was extract of tree(Mokcho-ak)(75.0%). Aloe(61.1%), Charcoal(22.2%) were also commonly used. Conclusion : It seems the frequency of folk remedies used were related to severity of AD.

The results obtained from te field investigations of Chuja Island conducted for 5 days from July 18 to 22, 1980 and from August 12 to 16, 1981 are summarized as follows: Vascular plants of this island disclosed by the present study consisted of 86 families, 210 genera, 228 species, 38 varieties and 4 래금. Nineteen species of evergreen broad-leaved trees were discovered, including Litsea japonica Juss, Camellia japonica L. and Machilus thunbergii Sieb. et Zucc. These indeciduous latifoliate trees were preserved in poor condition. Ten-twenty years old Pinus thunbergii was confirmed to be the predominant species. Seaside plants encountered were 6 species, including Vitex rotundifolia L. Fil. and Asterspathullfoius Max., but they were poorly distributed. Naturalized plants comprised a total of 12 species. This varied number of species is considered attributable to the frequent access of men owing to convenient marine traffic. the destruction of vegetation of this island may be attributed to human interference (loggin for boat construction, building and charcoal materials) ever escalated by high population density. It is worthy of noting that Bochmeria penosa Nakai et Stake which forms a large community in this island can be used as textile resources.

It is very important to determine the age of the Cultural Properties in archeology. In about 1950, W.F. Libby and a team of scientists at the University of Chicago developed the Radiocarbon Dating technique. Radiocarbon($^14$C) Dating is probably one of the most widely used and best known absolute dating methods. Radiocarbon ages are conventionally specified to the year 1950. This year is 0 BP year. BP is the initial of Before Present. The $^14$C within an organism is continually decaying into stable carbon isotopes. When $^14$C decays, it emits a $\beta$ - particle with an energy content of 156 KeV and becomes 14N. Only the $\beta$ - particle is detected by Liquid Scintillation Counting. $^14$C has a half life of 5730 years. It has been used to date samples as old as 50,000 years. Radiocarbon determinations can be obtained on organic material : wood, charcoal, shell, etc. The results of radiocarbon dating using Benzene Synthesizer and Liquid Scintillation Counter are KCP539 $4030\pm60$BP year, KCP540 $3980\pm60$BP year, KCP575 $4870\pm50$, KCP576 $100\pm50$BP year, KCP577 $130\pm50$BP yea and KCP578 $210\pm70$BP year.

CJ-50002 is an oral vaccine against V.vulnificus infection composed of whole cell lysate of V. vulnificus. The general pharmacological properties of CJ-50002 were evaluated in various animals and in vitro system. CJ-50002 at oral doses of 0.2, 2 and 20 mg/kg had no effect on general behavior in mice, chromo- and electro-convulsions in mice, writhing syndrome induced by acetic acid in mice, body temperature in rats, charcoal meal propulsion in mice and urine and electrolytes excretion in rats. However, oral administration of CJ-50002 at dose of 20 mg/kg prolonged the hexobarbital-inuced sleeping inducing time in mice. In anesthetized dogs, CJ-50002 showed no effect on blood pressure, heart rate and ECG but decreased the respiratory rate and femoral blood flow at dose of 20 mg/kg. p.o. CJ-50002 had no effect on the contractile response of the isolated guinea pig ileum to various spasmogen at concentrations of 0.2, 2 and 20 $\mu\textrm{g}$/ml, respectively. Since these pharmacological effects of CJ-500o2 were observed at dose much greater than those in clinical use (approximately 0.16 mg/kg, p.o.), it is likely that this vaccine may be relatively free of undesirable effects in clinical practice.

DK1001 is a thebain derivative, which is newly synthesized as an alkaloid analgesic. This study was designed to study effects of DK1001 on the ligands binding to the opioid receptor subtypes, and general pharmacology of DK1001. DK1001 inhibited the binding of [$^3H$]DAMGO, a selective mu-subtype agonist, to the opioid receptor of rat forebrain in a concentration-dependent manner. $EC_{50}$ of DK1001 was significantly lower than that of morphine. DK1001 inhibited the binding of 〔$^3$H〕DPDPE, a selective delta-subtype agonist concentration-dependently. DK1001(0.5 mg/kg) had no effects on behavior, body temperature, blood pressure. respiratory rate, and intestinal charcoal propulsion of mice. In addition, DK1001 did not affect on the contractilities of isolated muscle strips of aorta, ileum, and trachea of rats. These results suggest that DK1001 might be a potent analgesic without serious side effects.

Purpose: The number of glyphosate and glufosinate intoxication cases are increasing in Korea. This study was undertaken is to compare the clinical manifestations of poisoning by these two herbicides and to document severities and clinical outcomes. Methods: We retrospectively evaluated cases of glyphosate or glufosinate intoxication among patients that visited our emergency department between January 1, 2013, and December 31, 2017. Incidences of intoxications were analyzed over this five year period, and underlying diseases, transportation, mental state, shock occurrence, inotropics, gastric lavage, charcoal administration, intubation and ventilator therapy, and hemodialysis were investigated. In addition, we included transfer to the intensive care unit, incidences of pneumonia and of other complications, death, and hopeless discharge. Results: There were 119 cases of glyphosate intoxication and 42 of glufosinate intoxication. Levels of consciousness were lower for glufosinate and vasopressor usage was higher due to a high shock rate (p=0.019). In addition, many patients were referred to the ICU for intubation and ventilation. The incidences of pneumonia and of other complications were significantly higher for glufosinate. Conclusion: Overall glufosinate intoxication was found to be more severe than glyphosate intoxication as determined by complication and ICU admission rates.
