Over-the-counter (OTC) drugs refer to medicines that are generally safe when used according to the product label. We aimed to assess and reflect upon changes in perception of health and health-related demands by decades in Korea according to the consumption and sales trends of OTC drugs. This study was conducted by literature search on the production and sale rankings of OTC drug market in Korea. Changes in the OTC drug market were analyzed and organized by decades to evaluate changes in drug demands and the influence of national and societal factors. There was a specific trend in the most popular drugs by decades. In the 1950s, drugs of top necessity were antibiotics and helminthics. In the 1960s, the pharmaceutical industry quickly grew and invigorators, such as Bacchus$^{(R)}$, Alps$^{(R)}$, Aronamin$^{(R)}$, were top manufactured drugs. Popularity of these invigorating drinks and vitamin products continued until the 1990s. In 1990s, sales of topical nonsteroidal anti-inflammatory drugs (Ketotop Plaster$^{(R)}$, Trast Patch$^{(R)}$), and in 2000s, gum disease medicine (Insadol$^{(R)}$) and liver and intestine supplement (Ursa$^{(R)}$) were prominent. However, after the separation of prescribing and dispensing in 2000, the sales of OTC drugs decreased dramatically from 58.7% of the total market share in 1990s to 39.6% in 2000 and this trend has continued. In 2012, thirteen OTC drugs were allowed to be sold in convenience stores, and as the sales of health functional foods have been expanding beyond pharmacies, sales of invigorators and nutritional supplements in pharmacies have continued to decrease. As government's drug expenditure will continue to grow, reclassification of OTC drugs based on established safety information and deliberate team efforts on continued development of OTC drugs to meet the health demands of Koreans are required by the healthcare professionals, pharmaceutical industries, and the government.

It's a threat for the public health that H1N1 (Influenza virus A) causes disease and transmits among humans. WHO (world health organization) declared that the infections caused by the new strain had reached pandemic proportions. The approved neuraminidase inhibitors (Zanamivir and Oseltamivir) and related investigative drug (BCX-1812) are potent, specific inhibitors of influenza A and B viruses. These drugs are highly effective to prevent influenza A and B infections. Early therapeutic use reduces illness duration and respiratory complications. Recently, we found one of the potent inhibitor of erystagallin A ($IC_{50}$ of 2.04 ${\mu}M$) for neuraminidase target, this inhibitor shows most similar structure to its natural substrate, sialic acid. Therefore, we chose 1l7f to get the receptor structure for docking study among many crystal structures. A docking study has been performed in Surflex-Dock module in SYBYL 8.1. In the present study, we attempt to compare the docking studies of pterocarpin and erystagallin A with neuraminidase receptor structure. In the previous report, the methoxy group of pterocarpin had H-bonding with Arg residues. The present docking results for erystagallin A showed the backbone of hydroxyl group shows significant H-bonding interactions with Arg152 and Arg292. The results showed that erystagallin A interacts more favorably with distinctive binding site rather than original active site. Therefore, we tried to reveal plausible binding mode and important amino acid for this inhibitor using docking and site id search calculations of Sybyl. The results obtained from this work may be utilized to design novel inhibitors for neuraminidase.

Objectives: The aim of this study is (1) to investigate the historic changes and pharmacological efficacies of Woohwangchungsim-won and (2) to discuss the necessities for Woohwangchungsim-won's clinical applications. Methods: This study was performed through (1) investigating the ancient literature records related with Woohwangchungsim-won and analyzing Woohwangchungsim-won's composition, dosage and indications, (2) searching articles about Woohwangchungsim-won on 10 major Korean web and 3 major foreign web article search engines and analyzing Woohwangchungsim-won's pharmacological efficacies and indications. Results: Woohwangchungsim-wom has been used for cerebrovascular diseases such as stroke and palpitation. Also, there are some ancient literature records of Woohwangchungsim-won's clinical applications in neuropsychiatric disorders such as depression and bipolar disorder. In addition, there have been a number of experimental studies which demonstrate Woohwangchungsim-won's neuroprotective effect on cerebral cortex and hippocampus injury. So, it is possible to infer that Woohwangchungsim-won can be used for the treatments of neuropsychiatric disorders associated with neuronal cell death in cerebral cortex and hippocampus. But there have been no or less experimental studies which demonstrate the pharmacological efficacy of Woohwangchungsim-won on such disease. Conclusion: It is necessary that further experimental studies which demonstrate Woohwangchungsim-won's pharmacological efficacy on neuropsychiatric disorders should be done and Woohwangchungsim-won's clinical applications should be expanded on the basis of those related experimental results.

Objectives : The purpose of this study is to explore the trends of Chuna(manipulation) treatment on neck pain and cervical disc displacement. Methods : We set up the two searching strategies and investigated the latest clinical trials on Chuna(manipulation) therapy for Neck disorders and cervical disc herniation through PubMed search. The searched papers were analyzed and the year, journals, article types of literatures were examined. Of the articles, Randomized controlled trials(RCTs) are assessed by Jadad scale. Results : Studies on Chuna(manipulation) treatment to cervical disc herniation were very few. Articles on Chuna(manipulation) treatment to neck pain were relatively more than those of cervical disc herniation. The most frequently published journal was J Manipulative Physiol Ther. The main design of study was RCT. The limited quality assessment of RCT was conducted by Jadad scale and the average Jadad score was 1.73, which indicates low quality in terms of Jadad evaluation criteria. Conclusions : International trends of studies on Chuna therapy of cervical disease is increasingly reviewed. Although this review has several limitations, analyzing the latest trends of studies on Chuna(manipulation) treatment on neck pain and cervical disc displacement is necessary for further studies.

The purpose of this study was to quickly and effectively identify the Nosema disease of bumblebees in Gangwon Province in Korea. Bumblebees are crucial pollinators of various crops, and microsporidia are the critical pathogens of these hosts. When bumblebees are infected with Nosema bombi, their abdomens can become distended. Paralyzed and infected workers often become sluggish and die early. We have identified the morphology of the microsporidium by light and electron microscopy, and found it to have fairly small oval spores, as has been described previously in many other articles. For the specific and sensitive diagnosis of the microsporidian parasite N. bombi in bumblebees, we have developed an improved method of the polymerase chain reaction (PCR) for expeditious diagnosis. Two pairs of primers were tested on N. bombi and the related microsporidia Nosema apis and Nosema sp., both of which infect Bombus ignitus and Bombus hypocrita sapporoensis. Furthermore, we have verified and analyzed the 16SrRNA sequence data of N. bombi in bumblebees by using the Basic Local Alignment Search Tool (BLAST) server at the National Center for Biotechnology Information.

The immune staus is known to be decreased in malignant disease and radiation therapy (RT), used as a therapeutic tool, further decrease this-attenuated immune status. We measured the number of peripheral lymphocytes, its subsets and lymphoblast transformation for PPD, PHA, monoclonal antibodies including anti-CD3 and anti-CD2 before and after RT in 19 patients with squamous cell lung cancer to search the fine mechanism behind the RT-induced attenuation of lymphoblast transformtion for mitogens and antigen. The results were as follows; 1) The number of lymphocytes and its subsets decreased significantly after RT, but the percentages of lymhocyte subsets did not change aftr RT except interleukin-2 receptor positive T lymphocytes. 2) The function of lymphoctes, measured by lymphoblast tranformation for PHA and PPD, decrased after RT and the compositions of PBMC used for lymphoblast transformtion were not different before and after RT. 3) The mitosis of lymphocytes to anti-CD2 or anti-CD3 decreased significantly after RT. And IL-2 plus anti-CD3 increased the mitosis than that of anti-CD3 only after RT, but before RT there was no difference. In conclusion, we suggested the fine mechanism behind the RT-induced attenuation of immune response might be the dysfunction of lymphocytes in terms of impaired synthesis of IL-2 rather than the decrease of circulating lymphocyte numbers.
