Recently, nonsteroidal anti-inflammatory drugs (NSAIDs) have been found to be useful in the chemoprevention of colon cancer. To investigate whether indomethacin, an NSAIDs, induces apoptosis and thus assess the possibility of its application in the chemoprevention of human lung cancer, we have performed MTT assay, TUNEL assay, DAPI staining, and flow cytometric analysis using human lung carcinoma cell line NCI-H1299. Through morphological and biochemical analyses, it was demonstrated that NCI-H1299 cells treated with indomethacin (0.5 mM) exhibit classical apoptotic features. These results suggest that indomethacin induces apoptosis in NCI-H1299 cells and that NSAIDs, including indomethacin, may be a useful tool for the chemoprevention of human lung cancer.

Background: Nursing college students are exposed to information about diseases or drugs, and are likely to have a distorted perception of drug knowledge or behavior. The study aimed to identify knowledge and attitude about drugs and current status of self-medication among nursing students. Methods: The subjects were 172 nursing students from a university in Busan. Data were collected with structured questionnaires and analyzed using descriptive analysis, t-test, and one-way ANOVA using SPSS 23.0. Results: Nursing students had a high level of knowledge about drugs, but attitudes toward drugs were relatively low. 83.7% of patients had experience of self-medication. The methods to acquire information for self-administration were 29.9% by smart phone and 27.1% by internet. The use of nonsteroidal anti-inflammatory drugs (NSAIDs) among self-medication drugs was the highest. The most common reason for self-medication was 'I thought it to be a mild disease', and the pharmacists were the most affected by choice of self-medication. The knowledge about drugs was statistically significant according to grade, school life satisfaction and subjective health status. The attitudes about medication were statistically significant according to grade and self-medication experience. Conclusion: Nursing college students need drug safety education to improve awareness and practice of correct drug use.

A survey we conducted suggests that the ingestion of veterinary drug residues in edible animal parts constitutes a potential health hazard for its consumers, including, specifically, the possibility of developing multidrug resistance, carcinogenicity, and disruption of intestinal normal microflora. The survey results indicated that antibiotics, parasitic drugs, anticoccidial, or nonsteroidal anti-inflammatory drugs (NSAIDs) are broadly used, and this use in livestock is associated with the appearance of residues in various animal products such as milk, meat, and eggs. We observed that different cooking procedures, heating temperatures, storage times, fermentation, and pH have the potential to decrease drug residues in animal products. Several studies have reported the use of thermal treatments and sterilization to decrease the quantity of antibiotics such as tetracycline, oxytetracycline, macrolides, and sulfonamides, in animal products. Fermentation treatments also decreased levels of penicillin and pesticides such as dimethoate, malathion, Dichlorodiphenyldichloroethylene, and lindane. pH, known to influence decreases in cloxacillin and oxacillin levels, reportedly enhanced the dissolution of antimicrobial drug residues. Pressure cooking also reduced aldrin, dieldrin, and endosulfan in animal products. Therefore, this review provides updated information on the control of drug residues in animal products, which is of significance to veterinarians, livestock producers, and consumer health.

Nonsteroidal anti-inflammatory drugs (NSAIDs), particularly the highly selective cyclooxygenase (COX)-2 inhibitors have been shown to decrease the growth of tumor, in part, by inhibition of neovascularization. Recently, besides mature endothelial cells, endothelial progenitor cells (EPCs) have been shown to contribute neovascularization in angiogenic tissues. In this study, we addressed a question whether nimesulide, a selective COX-2 inhibitor, could affect differentiation of EPCs into adhesive endothelial cells in vitro. Total mononuclear cells were isolated from cord blood by Ficoll density gradient centrifugation, and then the cells were incubated with nimesulide or vehicle control for 7 days. The number of adherent and spindle-shaped cells decreased by nimesulide treatment in a concentration-dependent fashion at a concentration range of 5 - 200 ${\mu}M$. Moreover, the adherent cells double positive for DiI-ac-LDL uptake and lectin binding significantly decreased upon nimesulide treatment. There was no change of expression of CD31 between treatment and control groups, whereas slight reduction was detected upon treatment in expression of VE-cadherin, ICAM-1, vWF, ${\alpha}v$, and ${\alpha}5$. Nimesulide also reduced cell viability during first 3 days' culture and induced apoptosis in adherent EPCs, resulting in increased annexin-V-positive and propidium iodide-negative cells. Taken together, these results suggest that nimesulide could be applied for the inhibition of new vessel formation, in part, by inhibiting differentiation and survival of EPCs.

Objective: The purpose of this study was to report the effectiveness of Korean medicine in the treatment of functional dyspepsia in a fibromyalgia patient with a history of long-term NSAIDs use. Methods: The patient was diagnosed as a Soeumin, one of the four constitution types in Korean medicine, and treated with herbal medicines such as Seungyangikgibuja-tang and Pyeongjinsunjeom-san. Acupuncture and moxibustion treatment were also performed. The severity of symptoms was assessed using the Numerical Rating Scale (NRS) of epigastric pain, daily oral intake changes, the Korean Gastrointestinal Symptom Rating Scale (KGSRS), the Gastrointestinal Symptom Score (GIS), and the Functional Dyspepsia-Quality of Life (FD-QOL) score. Results: After treatment for 48 days, the severity of epigastric pain decreased from NRS 8 to NRS 0, and daily oral intake was increased. The KGSRS score decreased from 55 to 43, the GIS score was reduced from 18 to 10, and the FD-QOL score also decreased from 69 to 55. Conclusions: This study suggests that Korean medical treatment could be an effective option for treating functional dyspepsia in fibromyalgia patients with a history of long-term NSAIDs use.

Rheumatoid arthritis(RA) is the most common inflammatory joint disease and a major cause of disability, morbidity, and mortality. It occurs worldwide, affecting approximately one percent of adults. Inflammation of the synovial membrane surrounding a joint leads to swollen, tender, and stiff joints RA has no known cure and the diagnosis is made based on clinical criteria and many different options exist for treatment. All of these factors magnify the importance of the patient-physician interaction and place a premium on the art rather than the science of medicine. The major goals of therapy for RA are to relive pain, swelling, and fatigue; improve joint function; stop joint daage, and prevent disability and disease-related morbidity. Some combination of nonsteroidal anti-inflammatory drugs(NSAIDs), steroids, and DMARDs is necessary in almost patients. In many combinations of different DMARDs or DMARDs plus biologicals are necessary for optimal control. Additionaly, all patients with RA should be educated about their disease and the therapies that will be used. Patient education is essentially early in the disease course and on going basis Much research is focused on the further development of biological agent for treatment of RA. Elucidation of the trigger or trigers for RA may allow us to begin to think about prevention of RA.

The bone resorbing activity of $PGE_2$ and elevated level of prostaglandins(PGs) and thromboxanes (TXs) in inflamed gingiva which are cyclooxygenase(C) metabolites have been well documented. Nonsteroidal anti-inflammatory drugs(NSAIDs) have been known to suppress gingival inflammation and bone resorption through the specific inhibitory action on the C pathway thereby decrease of various C metabolites. Recent studies provide unequivocal results that gingival tissue metabolizes arachidonic acid(AA) mainly through lipoxygenase(L) pathway. And the results of our previous experiments suggest that indomethacin may have inhibitory action on L as well as C. Thus we started this study to show the influences of several C inhibitors on the L activity at therapeutic and toxic dosage. Periodontal tissue samples were obtained from patients with advanced periodontitis and incubated with $^{14}C-AA(0.2{\mu}Ci)$ and various enzyme inhibitors. The tissue lipid extracts were separated by means of thin layer chromatography(TLC) and analyzed by means of autoradiography and TLC analyzer. Our results showed that aspirin inhibited C more selectively than L, however at higher concentration it also decreased HETEs production significantly. Indomethacin showed dose-dependent inhibition of L as well as C and all of the L metabolites were decreased to the same degree by high concentration of indomethacin. AA-861, which is an experimental tool of selective L inhibitor, showed inhibition of HETEs production but no effect on the production of $TXB_2$, PGs and $LTB_4$. Various propionic acid derivatives NSAIDs(ibuprofen, flurbiprofen, naproxen) showed the same patterns of effect on AA metabolism each other that was profound inhibition of PGs production, to the less degree HETEs and $TXB_2$ production, and of no effect on the $LTB_4$ production.

When stenting is applied to treat myocardial infarction, antiplatelet agents are administered to prevent thrombosis, which increases the risk of bleeding. Patients with myocardial infarction are also more likely to have osteoarthritis simultaneously, because both diseases occur frequently in elderly patients. Patients with osteoarthritis often use analgesics, especially nonsteroidal anti-inflammatory drugs (NSAIDs); hence, patients with both diseases use analgesics and antiplatelet agents simultaneously. The risk of bleeding increases with the use of antiplatelet agents and this is further increased when NSAIDs are added. We would like to report a case that reflects this situation. A 60-year-old man underwent stenting after ST-elevation myocardial infarction, and was treated with aspirin and clopidogrel. This patient also received a pelubiprofen prescription from another physician to treat osteoarthritis. After the patient took pelubiprofen twice, he found a bruise on his wrist and reported it to the pharmacist. It is unlikely that this is rare in community pharmacies, so pharmacists should pay careful attention to the concomitant administration of analgesics to patients receiving antiplatelet agents and should provide appropriate education to patients.

연구 방법 : Nonsteroidal anti -inflammatory drugs (NSAIDs)는 대장앙의 항암 예방약제로 사용되고 었다 지속적으로 NSAIDs를 복용하면 대장암에 걸릴 위험도가 40-50% 감소되는 것으로 알려져 있다. NSAIDs가 대장암에서 종양의 크기를 감소시키는 것에 대한 정확한 기전은 알려져 있지 않으나, 일부 연구자들은 NSAIDs를 고농도로 투여하였을 때 세포 주기를 조절하는 유전자 발현의 변형과 세포고사의 유도로 설명하고 있다. 그러나 폐암에서 NSAIDs의 암 예방효과에 대해 확립 된 바 없어, 저자들은 NCI-H1299 세포주에서 NSAIDs가 세포고사를 유도하는지 알아보고자 하였다. 방 법 : 세포 독성은 MTT 방법으로 측정하였고, 세포고사를 알아보기 위해 유세포 분석과 핵산 염색을 시행하였다. 세포고사의 기전을 알아보기 위해 caspase family의 활성을 측정하였고, 세포고사의 마지막 단계인 PARP와 ICAD의 분절을 westem blot으로 확인하였다. 결 과 : NCI-H1299 세포에서 NaSaL 처리 시 생존율이 농도와 시간에 의존적으로 유의하게 감소하였고, 생존율의 감소는 세포주기에서 $subG_0/G_1$의 증가와 핵산 염색시 핵의 분절의 관찰로서 세포고사가 일어남을 관찰하였다. 10 mM NaSaL 처리 후 caspase-3 protease의 활성은 24시간에 증가하여 30시간에 최고에 이르고 감소하였으나 caspase-6, 8, 9 proteases의 활성은 의미 있는 증가가 없었다. PARP와 ICAD의 분절은 농도와 시간 의존적으로 증가하였다. 결 론 : NCI-H1299 폐암 세포주에서 NaSaL은 caspase-3 protease의 활성을 통하여 유도되었다.
