Background: Solar urticaria (SU) is an uncommon type of photodermatoses characterized by erythematous wheal with pruritus after sunlight exposure, which shows a female predominance. Only a few studies to analyze the clinical features of SU were reported in Asia. Objectives: We aimed to analyze the clinical and photobiological characteristics of SU in Korea. Methods: We retrospectively investigated the medical records of patients with SU who visited the department of dermatology, Konkuk university medical center from January 2005 to January 2020. Results: Of a total of 44 patients, 36 (81.8%) were male and 8 (18.2%) were female. The mean age at onset was 17.6 years (range, 5-47) and the mean threshold time was 19.7 minutes. Among 32 patients who underwent phototesting, the action spectrum most commonly implicated was ultraviolet (UV) A only in 12 (37.5%), and then visible light (415nm) only was responsible for SU in 8 (25.0%). Three patients (9.4%) were induced by both UVA and visible light (415nm). Even 4 patients (12.5%) were triggered by only natural sunlight. Serum immunoglobulin E levels were measured in 33 patients, and 17 (51.5%) showed values higher than normal. The treatment most widely used were oral antihistamine (43.2%), followed by phototherapy (13.6%). Conclusion: SU is a rare photodermatosis in Korea, which shows a male preponderance. In this study, UVA and visible light (415nm) were predominant action spectrum of SU.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

Basal cell carcinoma(BCC) and squamous cell carcinoma (SCC) are very prevalent neoplasms of the human skin. Ultraviolet radiation in sunlight is a well-established mutagen of the p53 gene and is one of basal cell carcinoma and squamous cell carcinoma. The newly-formed vascular network is important for neoplasms to grow beyond a size of about 1 ㎣. Recent reports have suggested the hypothesis that a mutant p53 protein is closely related with capillary density. Immumohistochemistry for p53 protein and CD34 was performed in 20 cases of BCCs and 14 SCCs to evaluated the relationship between p53 protein and capillary density. The results were as follows:1. The microvessels stained by CD34 were mainly located in the interface of tumor cells and stroma. 2. There was no difference in the microvessel density according to the histologic types and age of the patients, but a higher microvessel density was noted in male patients. 3. The aggressive BCCs and the less-differentiated SCCs showed higher p53 immunostaining. 4. The mean microvessel density of cases showing strong positive immunostaining of the p53 gene(54.73±17.75) was higher than that of others(39.75±18.30). These results suggested that p53 protein expression and microvessel density are not related to the histologic types and age of the patients, but that differentiation and biologic behavior such as the infiltrating property of tumors and the microvessel density are closely related to p53 protein expression.

In order to characterize pharmacokinetic profiles according to route of a new enrofloxacin salt form (Enrotil®), it was given to 4 healthy pigs via oral (p.o.), intramuscular (i.m.) or intravenous (i.v.) administrations at a dose rate of 5 ㎎/㎏ body weight. Enrofloxacin (ENFX) in serum was detected by bioassay using E. coli BE1186 as a test organism. The biological elimination half-lives (t_1/2(β)) of ENFX were 6.76±0.99 h (i.v.), 7.16±2.30 h (i.m.) and 11.45±3.90 h (p.o.), Volume of distribution (Vd) of enrofloxacin was 2.20±0.31 L/㎏ (i.v.), 2.52±0.60 L/㎏ (i.m.) and 1.88±0.33 L/㎏ (i.m.). Mean residence time (MRT) was 8.77±1.26 h after i.v. injection and the maximal concentration time (Tmax) following p.o. and i.m. administration was 0.76±0.09 h and 0.60±0.12 h, indicating a rapid absorption from these routes. Bioavailibility (F) was calculated as 64.1% for p.o. administration and 59.71% for i.m. injections. In summary, the newly formulated enrofloxacin salt form has shown a high water solubility, rapid absorption and large tissue distribution, suggesting a potential antibacterials for oral application on a large scale in veterinary sectors.

In our study, the noise levels of the schools, the hospitals and the apartment complexes located near the main street in Masan city were computed by the computer simulation method. The sourse of noise were mainly traffic noise. The noise level chart was attained and compared with the values which was investigated in 1988. The noise values of hospitals, schools and apartment complexes were generally increased by 0 ~3 dB over those of 1988. The noise volues of twenty nine schools, seven hospitals, twenty two apartments and twenty three apartment complexes were higher than the international allowance(55dB) for city. But the noise levels of eighteen schools(62%), tow hospitals(29%), nine apartments(41%) and five apartment complexes(22%) were low than our national allowance(65dB) for city. The noise problems of three hospitals, six cohools, thirteen apartments, and nine apartment complexes were very critical. We have suggested possible improvement methods for the noise problems of the traffic.
