Varicella (chickenpox) is a highly contagious airborne disease caused by primary infection with the varicella zoster virus (VZV). Following the resolution of chickenpox, the virus can remain dormant in the dorsal sensory and cranial ganglion for decades. Shingles (herpes zoster [HZ]) is a neurocutaneous disease caused by reactivation of latent VZV and may progress to postherpetic neuralgia (PHN), which is characterized by dermatomal pain persisting for more than 120 days after the onset of HZ rash, or "well-established PHN", which persist for more than 180 days. Vaccination with an attenuated form of VZV activates specific T-cell production, thereby avoiding viral reactivation and development of HZ. It has been demonstrated to reduce the occurrence by approximately 50-70%, the duration of pain of HZ, and the frequency of subsequent PHN in individuals aged ${\geq}50$ years in clinical studies. However, it has not proved efficacious in preventing repeat episodes of HZ and reducing the severity of PHN, nor has its long-term efficacy been demonstrated. The most frequent adverse reactions reported for HZ vaccination were injection site pain and/or swelling and headache. In addition, it should not be administrated to children, pregnant women, and immunocompromised persons or those allergic to neomycin or any component of the vaccine.

Volatile organic compounds emitted to the atmosphere can cause adverse effects on human health and participate in photochemical smog formation reactions. The destruction of a series of VOCs has been carried out by non-thermal plasma in other researches. And the characteristic of non-thermal plasma was operated at atmospheric pressure and low temperature. A new type non-thermal plasma reactor was investigated combined Glidarc plasma with water jet in this research. Also, it was found that the water-jet had an significant effect on the toluene removal efficiency. But too much water content does not favor toluene decomposition by decreasing of reaction temperature. The input toluene concentration, gas flow rate, water flow rate and specific energy input were used as experiment variables. The toluene removal efficiency, energy efficiency and specific energy input were 75.3%, 146.6 g/kWh and $1.12kWh/m^3$ at a water flow rate of 100 mL/min.

In organic chemistry amide synthesis is performed through condensation of a carboxylic acid and an amine with releasing one equivalent of water via the corresponding ammonium carboxylate salt. This method is suffering from tedious processes and poor atom-economy due to the adverse thermodynamics of the equilibrium and the high activation barrier for direct coupling of a carboxylic acid and an amine. Most of the chemical approaches to amides formations have been therefore being developed, they are mainly focused on secondary amides. Direct carbonylations of tertiary amines to amides have been an exotic field unresolved, in particular direct carbonylation of trimethylamine in lack of commercial need has been attracted much interests due to the versatile product of N,N-dimethylacetamide in chemical industries and the activation of robust N-C($sp^3$) bond in tertiary amine academically. This review is focused mainly on carbonylation of trimethylamine as one of the typical tertiary amines by transition metals of cobalt, rhodium, platinum, and palladium including the role of methyl iodide as a promoter, the intermediate formation of acyl iodide, the coordination ability of trimethylamine to transition metal catalysts, and any possibility of CO insertion into the bond of Me-N in trimethylamine. In addition reactions of acyl halides as an activated form of acetic acid with amines are reviewed in brief since acyl iodide is suggested as a critical intermediate in those carbonylations of trimethylamine.

Food allergy is defined as an immunologically-mediated adverse reaction to food.The food allergy as a clinical entity has been recognized for many years, although there is yet no general consensus as to the incidence of this syndrome. One difficulty in studying food allergies has been the lock of a reasonable animal model in which reactions could be induced by orally administrating foods. It has been generally accepted that the initial target for an immediate reaction to food is the mast cells, within the gastronitestinal mucosa, and such cells are sensitize in vivo by food-specific immunoglobulin(Ig) E. Degranulation of these cells facilitates the entry of an antigenic epitope into the lymphatic system and blood stream, thereby causing further degranulation of the mast cells and basophils throughout the boy. Accordingly, the author attempted to develop an animal model that is indicative of evaluating IgE-mediated immediate hypersensitivity. It is also necessary to evaluate the effects of nutritional envioronments on dietary protein-dependent allergy and the regulatory mechanisms of dietary fats on IgE-mediated immune response. In this review, animal models to evaluate a food ingredient, effects of dietary fats and curcuminoids, milk whey protein hydrolysates on allergic reaction, and effect of dietary fat in splenic immune cells are presented.

Objective: This study is to evaluate the awareness, needs, and barriers in patient counseling for hospitalized foreign patients. As the number of foreign population increases in Korea, demands on quality of Korean health services are rapidly increasing. Previously most of the studies have focused on the availability and utilization of healthcare service, and prevalence of disease for foreigners, however, no study has been conducted on quality of direct-patient care such as patient counseling. Method: In the present study, a survey was conducted on a total of 161 participants between March 7 and May 7 in 2014. The study subjects were consisted with 103 foreign patients who had experienced inpatient care within 1 year and 58 hospital pharmacists who work in the hospital with foreign inpatients. Results: Firstly, the hospital pharmacists were highly aware of the necessity of counseling for foreign inpatients. Secondly, the largest portion of barrier to patient counseling service was accounted a lack of foreign language skills. Lastly, the monitoring of efficacy, potential adverse reactions and discharge follow-up were emphasized. Conclusion: Effective communication skills would be essential to improve pharmaceutical care services to foreign inpatients.

Japanese encephalitis is the leading cause of viral encephalitis in Asia, where it accounts for up to 50,000 cases. Approximately 20% of affected patients die, and 30-50% of survivors have significant neurological sequelae. Inactivated mouse-brain derived Japanese encephalitis vaccines has been effectively implemented to control the disease effectively in Korea and several other Asian countries. However, the vaccine is expensive and difficult to produce, requires multiple doses, and has been associated with hypersensitivity reactions and rare adverse neurologicale events. The live-attenuated SA14-14-2 vaccine derived from primary hamster kidney (PHK) cells was developed in China and has been used there since 1988. Outside China, it has been licensed and used in Korea and several other Asian countries. This vaccine is effective and inexpensive. However, the lack of precedence for using a PHK cell substrate in a live-attenuated vaccine is a special issue of concern. The WHO working group has recommended additional safety studies in selected high-risk groups, as well as ongoing post-marketing studies to ensure long-term safety. Recently, a new inactivated vaccine and live-attenuated chimeric vaccine have been developed from vero cells. With this background, this article summarized the current status of Japanese encephalitis vaccination worldwide and in Korea.

There are several data in the literature indicating a great variety of pharmacological activities of Polypodium genus, which exhibit antiinflammatory and immunomodulatory activities. Since one of our main interests is to obtain natural immunoregulatory agents devoid of pharmacological adverse effects, we used flow cytometry analysis to highlight relative contributions of a water-soluble fraction of different concentrations of Polypodium rhizome extracts on lymphocyte subpopulations, NK and LAK activity. To measure their potential immunoregulatory activity a T cell proliferation assay in response to phytohemaglutinin (PHA) and mixed lymphocyte reactions were chosen. As a confirmatory bioassay we studied the effect of our extracts on CD45RO and CD95 antigen expressions. The results indicate that CD95 expression dramatically increases after peripheral blood lymphocyte activation and treatment with Polypodium leucotomus, cambricum and vulgare extracts, suggesting a powerful intrinsic pro-apoptotic effect.

The objective of this study was to link conformational changes of proteins at a water/methylene chloride interface to their destabilization upon emulsification. When 4 aqueous protein solutions (bovine serum albumin, $\beta$-lactoglobulin, ovalbumin, or ribonuclease) were emulsified in methylene chloride, considerable proportions of all the proteins became water insoluble aggregates. There were also noticeable changes in the compositions of their water-soluble species. A series of water/methylene chloride interfacial reactions upon the proteins was considered a major cause of the phenomena observed. Based on this supposition, the interfacial tension was determined by a Kruss DVT-10 drop volume tensiometer under various experimental conditions. It substantiated that the interfacial tension was high enough to cause the adsorption of all the proteins. Under our experimental conditions, their presence in the aqueous phase resulted in reductions of the interfacial tension by the degrees of 8.5 - 17.1 mN $m^{-1}$. In addition, dynamic changes in the interfacial tension were monitored to compare relative rates at which the adsorbed proteins underwent conformational, structural rearrangements at the interface. Such information helped make a prediction about how easily proteins would denature and aggregate during emulsification. Our study indicated that emulsifying aqueous protein solutions in organic solvents should be handled with care, due to adverse interfacial effects.

Objective: This study aimed to investigate pharmaceutical care for critically ill neonates and suggest targeted strategies compatible with the Korean health-system pharmacy. Methods: Articles that reported pharmacy practices for critically ill neonates were reviewed. Pharmaceutical care practices and roles of neonatal pharmacists were identified, and criteria were developed for neonates in need of specialized care by clinical pharmacists. Results: Neonatal pharmacists play many roles in the overall medication management pathway. For clinical decision support, multidisciplinary ward rounds, clinical pharmacokinetic services, and consultation for pharmacotherapy and nutrition support were conducted. Prevention and resolution of drug-related problems through review of medication charts contributed to medication safety. Pharmaceutical optimization of intravenous medication played an important role in safe and effective therapy. Information on the use of off-label medicine, recommended dosage and dosing schedules, and stability of intravenous medicine was provided to other health professionals. Most clinical practices for neonates in Korea included therapeutic drug monitoring and nutrition support services. Reduction in medication errors and adverse drug reactions, shortening the duration of weaning medicines, decreasing the use and cost of antimicrobials, and improvement in nutrition status were reported as the outcomes of pharmacist-led interventions. The essential criteria of pharmaceutical care, including for patients with potential high-risk factors for drug-related problems, was developed. Conclusion: Pharmaceutical care for critically ill neonates varies widely. Development and provision of standardized pharmaceutical care for Korean neonates and a stepwise strategy for the expansion of clinical pharmacy services are required.
