Background: The recognition of prevention and early detection of skin cancer has been increased more than before. Although skin cancer is not rare, most patients are little known about general awareness of skin cancer. Objectives: In this study, we survey the awareness and knowledge of skin cancer and sun protection behavior among South-Gyeongnam province. Methods: We reviewed a written questionnaire and patients’ self-checked records including patients’ basic medical information and knowledge of skin cancer protective modalities. Results: In total 284 subjects (94.7%(284/300), 67%(190/284) females, mean age 57.4 years) completed the survey. Most people (77.5%, 220/284) knew that the sun was most dangerous for their skin but relatively large portion of them (42.7%, 94/220) had no action to protective attitude like sun screen, large hat and gloves. Conclusion: The results show that many participants had known necessity of skin cancer prevention and importance of early detection, but didn’t have had any protective action. Therefore, a more effective skin cancer education and prevention program is needed. We suggest that the measurement of effects of a multimodal educational intervention on knowledge of sun protection practices and engagement in self sun-protection behaviors also need to be check.

Signalment: An 8-month-old female Alaskan malamute was presented for progressive cluster seizure disorder. Results: There were no abnormalities on neurological examination, survey radiographs, or blood analysis. Magnetic resonance (MR) imaging and computed tomography revealed extension of the olfactory bulb and frontal lobe into the nasal cavity. They also confirmed abnormal anatomy of the nasal turbinates within the rostral part of the nasal cavity and the absence of a cribriform plate. On T2-weighted and fluid-attenuated inversion recovery images, the herniated brain showed heterogeneous and hyperintense signals consistent with intraparenchymal edema. Transverse MR images showed brain herniation into the right frontal cavity and an asymmetrical lateral ventricle because of a left midline shift. On contrast-enhanced MR images, the protruding brain parenchyma was mildly enhanced. Ethmoidal encephalocele was suspected as the final diagnosis. Despite symptomatic treatment, the dog continued to exhibit seizures and was euthanized. Clinical relevance: Ethmoidal encephalocele is a rare disease in dogs. However, it could be considered as a cause of seizure in young dogs.

The College of Engineering was specialized to have a sole function for supplying technical high school teachers in 1977 and referred to as the College of Industrial Education according to the Government's policy. The economic impact mainly due to the oil-crises caused a severe problem to this college, namely discrepancy of supply to demand scale. Accordingly the number of student enrollment was to be fluctuated from 479 in 1979 through 800 in 1979 and 900 in 1980 to 430 in 1981. And the engineering departments have been attached to this Engineering Education College since 1981. These circumstanses met singnificant inefficiency in facility operation. This program aims at providing an overall relocation of the college facilities and preparing the practical system to make the joint-operation possible taking into account circulation, academic stream, budget, maintenance, etc. However this study could not get optimal spacing but some trade-off, considering the current situation.

Cimetidine is a histamine H₂-receptor antagonist, used for the treatment of endoscopically or radiographically comfirmed duodenal ulcer. pathologic GI hypersecretory conditions. and active, benign and gastric ulcer. Simple method for determining cimetidine in human plasma has been developed and validated. The analytical procedure for cimetidine showed a linear relationship in the concentration ranges from 0.05 to 5 pg/ml. Coefficient of variance (CV, ° o) for intraday and interdav validation and relative error (RE. ° o) were less than ±150 o. Based on this analytical method. the bioequivalence of two cimetidine 400 mg tablets, reference (Tagamet 400 mg) and test drug (Sinil CIMETIDINE 400 mg) was evaluated according to the guidelines set by the Korea Food and Drug Administration (KFDA). Release of cimetidine from the tablets in vitro was tested using KP VIII Apparatus II with various dissolution media (pH 1.2. 4.0. 6.8 butter solutions and water). Twenty-four healthy volunteers. 21.38±1.86 years in age and 68.71±8.68 kg in bode weight, were divided into two groups and a randomized 2x2 cross-over study was performed. After oral administration of a tablet containing 400 mg of cimetidine. blood samples were taken at predetermined time intervals and concentrations of cimetidine in plasma were determined using HPLC equipped with UV detector. The dissolution profiles of the two tablet formulations were very similar at all dissolution media. In addition. pharmacokinetic parameters such as AUC, and C_(max) were calculated and ANOVA was employed for the statistical analysis of parameters. The results were revealed that the diterences in AUCf and Cma, between the two tablets were 4.17% and 0.97% respectively. At 90% confidence intervals. the differences in these parameters were also within ± 20° o. All of the above mentioned parameters have met the criteria of KFDA guidelines for bioequivalence, indicating that the test drug tablet (Sinil CIMETIDINE tablet) is bioequivalent to Tagamet 400 mg tablet.

A self-microemulsifying drug delivery system (SMEDDS) was developed to increase the dissolution rate, solubility, and ultimately bioavailability of a poorly water soluble drug, lovastatin. SMEDDS was the mixtures of oils, surfactants, and cosurfactants, which emulsify under conditions of gentle agitation, similar to those which would be encountered in the gastro-intestinal (GI) tract. Various types of self-emulsifying formulations were prepared using four types of oil (Capryol 90, Lauroglycol 90, Labrafil M 1944 CS and Labrafil M 2125), two surfactants (Cremophor EL and Tween 80), and three cosurfactants (Carbitol, PEG 400 and propylene glycol). The efficiency of emulsification was studied using a laser diffraction size analyzer to determine particle size distributions of the resultant emulsions. Optimized formulations selected for bioavailability assessment were Carpryol 90 (40%), Cremophor EL (30%) and Carbitol (30%). SMEDDS containing lovastatin (20 mg and 5 mg) were compared to a conventional lovastatin tablet (Mevacor^? , 20 mg/tab) by the oral administration as prefilled hard gelatin capsules to fasted beagle dogs for in vivo study. The area under the serum concentration-time curve from time zero to the last measured time in serum, AUC_0→24h, was significantly greater in SMEDDS, suggesting that bioavailability increase 130% and 192% by the SMEDDS, respectively. The self-emulsifying formulations of lovastatin afforded the improvement in absolute oral bioavailability relative to previous data of lovastatin tablet formulation. These data indicate the utility of dispersed self-emulsifying formulations for the oral delivery of lovastatin and potentially other poorly absorbed drugs.
