Background: Although paclitaxel is a widely used chemotherapeutic agent for the treatment of solid cancers, side effects such as neuropathic pain lead to poor compliance and discontinuation of the therapy. Ethyl pyruvate (EP) is known to have analgesic effects in several pain models and may inhibit apoptosis. The present study was designed to investigate the analgesic effects of EP on mechanical allodynia and apoptosis in dorsal root ganglion (DRG) cells after paclitaxel administration. Methods: Rats were randomly divided into 3 groups: 1) a control group, which received only vehicle; 2) a paclitaxel group, which received paclitaxel; and 3) an EP group, which received EP after paclitaxel administration. Mechanical allodynia was tested before and at 7 and 14 days after final paclitaxel administration. Fourteen days after paclitaxel treatment, DRG apoptosis was determined by activated caspase-3 immunoreactivity (IR). Results: Post-treatment with EP did not significantly affect paclitaxel-induced allodynia, although it tended to slightly reduce sensitivities to mechanical stimuli after paclitaxel administration. After paclitaxel administration, an increase in caspase-3 IR in DRG cells was observed, which was co-localized with NF200-positive myelinated neurons. Post-treatment with EP decreased the paclitaxel-induced caspase-3 IR. Paclitaxel administration or post-treatment with EP did not alter the glial fibrillary acidic protein IRs in DRG cells. Conclusions: Inhibition of apoptosis in DRG neurons by EP may not be critical in paclitaxel-induced mechanical allodynia.

Contrast enhanced magnetic resonance imaging using gadolinium-based contrast agent (GBCA) is a very useful in vivo technique to visualize the inner ear pathology including endolymphatic hydrops. Although systemic intravenous (IV) administration can visualize the perilymph space, the visualization was possible by indirect passage of contrast agent through blood-perilymph barrier. All animal experimental procedures were performed under anesthesia with 5% isoflurane. Lipopolysaccharide (LPS) was instilled into the left tympanic cavity through the tympanic membrane using a sterile 27gauge needle to induce hydrops model. Tucker-Davis Technologies system was used to measure Auditory Brainstem Responses (ABRs). For intracerebroven-tricular (ICV) administration, 25 µmol of GADOVIST (Bayer, Berlin, Germany) was used and diluted GADOVIST injection was 10 µl. MR imaging was acquired with a 9.4 Tesla MRI scanner. Transmit-receive volume coil with 40 mm inner diameter and 75 mm out diameter was used. ICV administration well demonstrated the strong enhancement along the cerebrospinal fluid (CSF) microcirculation pathway including CSF fluid in the subarachnoid space and CSF space of the inner ear structures. On the other hand, IV administration showed no contrast enhancement along the CSF microcirculation pathway and showed weak enhancement in the inner ear structures. In case of rat hydrops model, ICV administration showed that the reduced contrast enhancement in the perilymph space of the hydrops induced inner ear compared to the contrast enhancement in the perilymph space of the normal inner ear. New systemic ICV administration method provide contrast enhancement of GBCA in the inner ear through CSF microcirculation pathway.

의료인이 환자에게 직접 조제한다는 이유로 의약품공급자로부터 의약품을 취득하여 보관하고 있다가 스스로에게 투약한 경우의 약사법상 쟁점을 검토하였다. 의료인이 자가 투약 행위를 한 경우 의약품공급자나 의료인이 약사법에 따라 형사처벌될 수 있다. 그 가벌성은 약사법에서 규정한 의약품 유통 질서 훼손에 있다. 첫째, 의약품공급자가 의료인에게 의약품을 판매하는 것은 약사법 제47조 제1항 제1호 나목 위반죄의 구성요건에 해당한다. 다만, 약사법상 허용되는 직접 조제를 위해 판매한 경우 형법상 정당행위에 해당하여 위법성이 조각된다. 그러나 의약품공급자가 의료인의 자가 투약 목적을 알면서도 의약품을 판매한다면 위법성이 조각되지 않아서 형사처벌될 수 있다. 둘째, 의료인이 약사법상 직접 조제를 위하여 의약품을 취득한다고 명시적, 묵시적으로 의약품공급자를 기망하고 의약품을 취득하여 자가 투약한 경우, 기망에 의한 의약품 교부로 의료인에게 형법상 사기죄가 성립할 수 있다. 셋째, 의료인의 자가 투약 시 약사법상 조제 행위가 수반되므로 약사법 제23조 제1항 위반죄의 구성요건에 해당한다. 이때 위법성이 조각되지 않는다. 왜냐하면 의료인의 자가 투약 행위는 약사법에서 의료인에게 부여한 특별한 지위를 남용한 것으로 의약품 유통 질서를 해치고 의약분업의 취지를 훼손하는 것이어서 형법상 정당행위로 볼 수 없기 때문이다.

A 5-year-old, 2.7 kg, spayed female Scottish Fold cat presented with hematemesis after administration of oral zaltoprofen, a non-steroidal anti-inflammatory drug, by the owner. Diagnostic imaging and blood analyses indicated development of acute kidney injury (AKI) resulting from zaltoprofen ingestion. To correct dehydration and anemic conditions, the cat received intravenous fluid therapy with whole blood transfusion and peroral N-acetylcysteine. Clinical signs resolved, but persistent azotemia was unresolved indicating that AKI could progress to chronic kidney disease. This case suggests that although zaltoprofen may have low adverse effects on humans, administration of zaltoprofen in cats can have serious adverse effects.

Hydrogels for medical devices such as hydrophilic dressing, moisturizing healing band, hydrophilic intravenous catheter and soft contact lens were evaluated for their cytotoxicity according to the International Organization for Standardization (ISO) procedures. To test indirect cytotoxicity of hydrogel products, dissolution medium and dissolution condition were selected based on the guideline for medical devices. Cytotoxicity was low in all the case of hydrogel products. Soft contact lens showed no significant difference in dissolution between complete medium and saline. Currently, there is no specific guidelineto test hydrogel for medical devices in Korea with consideration of characteristics of hydrogel. Thus, proper method of cytotoxicity evaluation should be selected depending on the characteristics and usages of hydrogels for medical devices.

Background: Although Korean government have been adopting several policies to expand coverage of National Health Insurance (NHI) program, the coverage rate is still below average across Organization for Economic Cooperation and Development countries. This study was to identify public perception on appropriateness of coinsurance rate and factors associated with coinsurance rate in National Health Insurance. Methods: For this cross-sectional study, 507 participants over aged 20 years were recruited from telephone surveys. Respondents experienced at least one and more visiting medical facilities due to medical problems in last 12 months. Demographic factors, socioeconomic positions, and experiences on medical utilization were measured in order to identify factors associated with perception appropriateness of coinsurance rate. Results: The 49.9% (n=209) of the public responded that the coinsurance rate of NHI program was appropriate. There were no differences in positive perception according to socio-demographic factors and experiences on medical utilization except for gender, residential area, and felt expensive when using medical services. People who felt burden of medical expenditure were more likely to perceive coinsurance rate inappropriate (odds ratio, 2.33; 95% confidence interval, 1.52-3.58) Conclusion: In spite of the relatively low coverage rate of NHI, this study identified that 49.9% of the public perceived the current coinsurance rate was adequate. However, people who felt the burden of medical expenditure were still had a negative perception of the coinsurance rate needed to decrease the coinsurance rate.

Background: The purpose of this study is to identify the factors infecting the medical care utilization from a new perspective by newly classifying the categories of administrative districts using the urban decline index and medical vulnerability index as indicators. Methods: This study targeted 150,940 people who used medical services using the 2015 cohort database (DB), 2010-2015 urban regeneration analysis index DB, and 2014-2015 public health and medical statistics DB. The decline of the region was classified using the urban decline index typed using k-means clustering and the medical vulnerability index typed using the quantile score calculation. Regression analysis was performed 3 times with medical expenditure, length of stay, and the number of outpatient visits as dependent variables. Results: There were 37 stable region (47.4%), 29 health vulnerable region (37.2%), and 12 decline region (15.4%). The health vulnerable region had lower medical expenditure, fewer outpatient visits, and a higher length of stay than the stable region. The decline region was all higher than the stable region but had no significant effect. Conclusion: The factors that cause the health disparity between regions are not only factors related to individual health behavior but also environmental factors of the local community. Therefore, there is a need for a systematic alternative that properly considers the resources within the community and reflects the characteristics of the population.

2,3,7,8-Tetrachlorodibenzo-$\rho$-dioxin(TCDD) is a ubiquitous, persistent environmental contaminant and the most powerful carcinogen categorized by IARC. Although the mechanism of carcinogenesis by TCDD is poorly understood, several studies have shown that the skin is one of target organs far TCDD. In this study, we investigated the neoplastic transformation of human keratinocyte-derived cell line, HaCaT, by chemical transformation method using N-methyl-N'-nitro-N-nitrorsoguanidine(MNNG) and TCDD. We found that subsequent exposure to TCDD for 3 weeks after initial exposure to MNNG markedly induced transformed cells. It was suggested that TCDD can act as a potent promoter in HaCaT cells. Furthermore, these transformed cells showed morphological alternations in soft agar and increased telomerase activity. Therefore, the TCDD treatment of HaCaT cells by initiated with MNNG could promote neoplastic transformation without stimulation by exogenous growth factors. As a result, TCDD had a strong potency as a promoter in nontumorigenic immortalized human epidermal keratinocytes.
