1.Candida albicans test for the screening of phototoxicity in anthistamines.
Korean Journal of Dermatology 1993;31(2):191-196
BACKGROUND: Antihistamine drugs are used widely in many conditions. Although some antihistamines may cause a photosensitive reaction,many physicians are not awae of it. OBJECTIVE: For examination of the phototoxic potential of antihistamines, we performed the Candida albiecrns test which is simple, cheap, and good for the screening of many drugs. MEHTODS: Thirty microliters of each solute of various antihistamines were applied to the Sabraud dextrose agar plate in which Candida albicans were applied diffusly. Four hours after the application, 60J/cm fo UVA was irradiated for two days. The irradiated. plates and nonirradiated control ones were incubated in a dark room for 48 hours, and examined for lear zones arround the drug, which means a positive results for the phototoxic potential of the drugs. RESULTS: Mequitazine, thiethylperazine, perphenazine and cllorromazine showed positive results, whereas others did not. An additional Candida albicans test using 0.1%, 0.01%, and 0.001% of the positive drugs revealed tht chlorpromazine, thiethylperazine aderphenazine showed positive results at 0.1%, but negative at 0.01 and 0.001%. Mequitazine was niegative at 0.1, 0.01, and 0,001%, Additional studies of the Candida albicans test using 5% and 10% of the diphenhydramine and dimenhydrinate, those were known photosensitizers but they slowed negative results at this study and revealed very weak posit,ive result in 10% diphenhydramine. CONCLUSION: A photosensitive reaction such as photoallergy and persistent light react,ion may be triggered by the phenothiazine antihistamines. Negative result in 1%, and very weak positive results in 10% diphenhydramine may be due to different mechanism of phototoxicity, or the low phototoxic potential of diphenhydrainine.

BACKGROUND: Chronic actinic dermatitis (CAD) is a rare disease worldwide. It has been defined on the basis of three criteria: 1) clinical - a persistent eczematous eruption on sun- exposed area with possible extension into non-exposed areas, 2) photobiological - a reduction in the minimal erythema dose to UVB irradiation, and possibly longer wavelengths, and 3) histologic - an appearance consistent with chronic eczema, with or without the presence of lymphoma-like changes. However, only a few clinicohistopathologic and photobiological analyses of CAD have been undertaken in Korea. OBJECTIVE: To explore photoallergens and/or allergens causing or thought to be associated with CAD in Korean patients, and to compare the photopatch or patch test results in Korea with those from other countries. METHODS: Thirty-five Korean patients with CAD were enrolled for this study. Photopatch tests were carried out by applying two sets of the Scandinavian photopatch series to each patient. Two days after application, the photopatch tests were analysed, and one set of the photoallergens was irradiated with 50% of the MED-UVA. Both sets of photoallergens were examined 2 days later. A European standard series was used to assess the patch tests. At two and four days after application, patch tests were analysed. RESULT: Twenty-seven of the 35 patients (77.1%) who had photopatch tests showed positive responses; balsam of Peru, promethazine HCl, perfume mix, fentichlor, chlorhexidine digluconate, and chlorpromazine HCl were the common photoallergens that elicited a positive response. Twenty-one of the 35 patients (70%) showed allergy to nickel, chrome, and/or ammoniated mercury. Noticeably, photoallergens such as balsam of Peru, perfume mix, cobalt, and captan revealed positive reactions in the patch tests, too. CONCLUSION: In 77.1% and 74.3% of CAD patients, photoallergens and allergens were identified, respectively. Among them, 57.1% showed positive reactions including both photopatch and patch tests. After the most frequent photoallergens, perfume and spices, and phenothiazines or related antihistamines ranked next and were found to be a unique characteristic to Korea. Photopatch and patchtests are the method for detecting photoallergens and allergens as important initiating agents and are the diagnostic tool for the epidemiologic study of CAD.

PURPOSE: This study was done to identify practical exercise performance and to define the factors related to exercise performance in middle-aged women. METHODS: The researchers collected data from 206 middle-aged women, ages 40 to 59. The measurements used were a scale for degree of exercise performance, and self-efficacy scale, affect, perceived barriers and benefits related exercise, body-shape perception, and the youngest child's education stage. The data were analyzed with SPSS/WIN 17.0 and SAS program using t-test, ANOVA, and stepwise multiple regression. RESULTS: Exercise performance showed significant differences according to body-shape perception (F=5.45, p<.01), the youngest child's education stage (F=4.44, p<.05). Exercise performance had a significant strong positive relation with self-efficacy (r=.616), a moderate relation with self-rated health (r=.428) and with affect related exercise (r=.519), a mild relation with perceived benefits (r=.339) and with social support (r=.239), and a negative mild relation with perceived barriers (r=-.330) with 99% significance. Self-efficacy, affect, perceived barriers, and the youngest child's education stage explained 46.4% of a variance in exercise performance in middle-aged women. The factor most influencing was self-efficacy related exercise at 37.9% of the variance. CONCLUSION: We can conclude that self-efficacy, affect, perceived barriers, and the youngest child's education stage should be considered as important factors for developing program of middle-aged women.

PURPOSE: The purpose of this study was to investigate the relationship between nurse managers' facilitative communication as perceived by nurses and nurses' self-esteem. METHODS: The subjects were 256 staff nurses at B hospital of C University in Kyeonggi-do. The data were collected between December 1, 2009 and January 12, 2010. The collected data were analyzed using the SAS program through t-test, ANOVA, Scheffe test, Pearson's correlation coefficients. RESULTS: Nurses' self-esteem was higher when nurse managers perceived them as facilitative communicators in empathic understanding and genuineness subgroup of facilitative communication (p<.05). There was a positive correlation between nurse managers' facilitative communication and nurses' self-esteem(r=.15, p=.015). Also there was a positive correlation among the nurse managers' facilitative communication subgroups, empathic understanding; genuineness; concreteness(r=0.18, p=.004; r=0.18, p=.003; r=0.19, p=.002) and nurses' self-esteem. CONCLUSION: Nurse managers are in need of facilitative communication. Therefore, job education and training for improving nurse managers' communication skills particularly related to empathic understanding, genuineness and concreteness are required.

6.A study on the consumer's perception of front-of-pack nutrition labeling.
Nutrition Research and Practice 2009;3(4):300-306
The goal of this research is to investigate the present situation for front of pack labeling in Korea and the perception of consumers for the new system of labeling, front of pack labeling, based on the consumer survey. We investigated the number of processed foods with front of pack labeling in one retailer in Youngin-si. And we also surveyed 1,019 participants nationwide whose ages were from 20 to 49; the knowledge of nutrition labeling, the knowledge of 'front of pack labeling', and the opinion about the labeling system. The data were analyzed using SAS statistics program. The results were as follows: 13.4% of processed foods had front of pack labeling, and 16.8% of the consumers always checked the nutrition labeling, while 32.7% of the consumers seldom checked it. In addition, 44.3% of the consumers think that 'front of pack labeling' is necessary, and 58.3% of the consumers think it is important to show the percentage of daily value as a way of 'front of pack labeling'. However, 32% of the consumer think the possibility of 'front of pack labeling' is slim. Meanwhile, 58.3% of the consumers think that it is important to have the color difference according to contents. The number of favorite nutrients in the front of pack was four or five. It seems that the recognition of current nutrition labeling has the influence on the willingness of using the future 'front of pack labeling'. Along with our study, the policy for 'front of pack labeling' has to be updated and improved constantly since 'front of pack labeling' helps consumer understand nutrition facts.

Journal of Laboratory Medicine and Quality Assurance 2009;31(2):281-285
BACKGROUND: Clostridium difficile is the most common pathogen of antibiotic-associated diarrhea. Toxigenic strains produce toxin A and toxin B. The pathogenicity of C. difficile is due to the production of these two exotoxins. This study aimed to evaluate diagnostic value of two enzyme immunoassay by comparison of concordance rate to diagnose C. difficile-associated infection. METHODS: C. DIFF QUIK CHEK (TECHLAB, USA) that detect glutamate dehydrogenase antigen and VIDAS C. difficile Toxin A&B (BioMerieux, France) that detect toxin A and toxin B were done in 122 fecal specimens to detect C. difficile. RESULTS: In the total 122 stool specimens, 17 cases showed positive results in both tests. One specimen showed discrepancy that positive result in VIDAS C. difficile Toxin A&B (relative fluorescence value, RFV=2.93) but negative result in C. DIFF QUIK CHEK. Therefore, the concordance rate between two tests was 95.1% (116/122). Both anaerobic culture and in-house PCR for toxin B were negative in the discrepant fecal specimen and there was no clinical evidence that support C. difficile-associated diarrhea, so we concluded result in VIDAS C. difficile Toxin A&B as false positive. CONCLUSIONS: Although these two enzyme immunoassays targeted different antigen, they showed high concordance rate. The discrepant case was concluded to false positive in VIDAS C. difficile Toxin A&B test because it showed negative results in culture and PCR for toxin B and there were no clinical evidences of C. difficile-associated infection. It could be needed for analysis about conditions that cause false positive result in enzyme immunoassays to detect C. difficile toxin.

8.Past, Present and Future of Psychopharmacology in Korea.
Korean Journal of Psychopharmacology 2005;16(4):257-271
History of psychopharmacology in Korea since 1885 was reviewed, when western medicine was firstly introduced to Korea. Barbiturates and fever therapy had been main therapies for mental patients until 1940s. The true era of psychopharmacology started around 1960 with introduction to Korea of chlorpromazine followed by other phenothiazines and meprobamate. Since then, Korean psychopharmacology has developed following international development in psychopharmacology and neuroscience. Around 1990s, second generations of antidepressants and antipsychotic agents had been introduced to Korea. These days, most major psychotherapeutic drugs have become available in Korea soon after they appeared in world market. Meanwhile most researches were clinical ones until 1990s. However basic researches have been limited due to not only lack of financial support but poor conditions for research. Recently general condition for research are improving with general economical development of Korea. Many young researchers have returned to Korea after years of training abroad and are leading researches and international activities. Future directions for researches in psychopharmacology and for activities of Korean College of Neuropsychopharmacology (KCNP) are discussed related to future social changes and especially focused on integration of drug treatment with psychosocial treatment.

OBJECTIVETo test the possibility that certain efficient substrates for lipoxygenase (LOX) produce shuttle oxidants that stimulate the generation of reactive oxygen species from other chemicals.
METHODSMetabolic interactions were conducted in vitro between chlorpromazine (BZ) or other phenothiazines and benzidine or other xenobiotics mediated by soybean lipoxygenase (SLO) or purified human term placental lipoxygenase (HTPLO) in the presence of hydrogen peroxide, and the rates of xenobiotics oxidation were measured by spectroscopic analysis.
RESULTSChlorpromazine cation radical (CPZ(*+)) generated by lipoxygenase triggered a rapid oxidation of benzidine to benzidine diimine cation. Under the experimental conditions used, the metabolic interaction resulted in a 42-fold greater stimulation than BZ alone in the rate of BZ oxidation. The magnitude of stimulation of benzidine oxidation exhibited a dependence on the pH of the reaction medium, amount of the enzyme, and concentration of chlorpromazine, BZ, and hydrogen peroxide. A number of other phenothiazines were also found to stimulate BZ oxidation, albeit to a lesser degree. Chlorpromazine cation radical stimulated the oxidation of all six other xenobiotics tested. The highest stimulation (94-fold) was noted in the oxidation of tetramethyl phenylenediamine to Wursters blue radical, while the lowest stimulatory response (2-fold) was observed in guaiacol. Preliminary data showed that purified HTPLO also displayed a similar stimulatory response to benzidine oxidation in the presence of chlorpromazine.
CONCLUSIONBoth soybean lipoxygenase and purified human term placental lipoxygenase can mediate stimulatory response to the oxidation of benzidine and other xenobiotics in the presence of phenothiazines.

OBJECTIVE: To investigate the patterns of antipsychotic use in China and to analyze the factors that influence antipsychotic prescriptions. METHODS: A standardized survey was conducted from May 20 to 24 2002 in five different regions of China with varying economic levels. The patterns of antipsychotic medication use were analyzed in a sample of 4,779 patients with schizophrenia. The survey gathered information on demographic characteristics, clinical profiles, and antipsychotic medications prescribed. Multiple logistic regression was used to analyze factors related to patterns of antipsychotic medication use. RESULTS: A plurality of patients with schizophrenia was treated with clozapine (39%); this was followed by risperidone, sulpride, chlorpromazine, perphenazine, and haloperidol. More than 56.3% of patients were treated with only one atypical antipsychotic. The mean daily dose of chlorpromazine was 365+/-253 mg (mean+/-standard deviation), and 6.5% of patients were treated with depot injections of typical antipsychotic medications. A total of 73.7% (n=3,523) of patients with schizophrenia received monotherapy, 24.8% (n=1,183) received two antipsychotics, 1.1% (n=52) received three antipsychotics, and one received four different antipsychotics. Patients often simultaneously received other classes of medications including anticholinergic agents, benzodiazepines, beta-blockers, antidepressants, and mood stabilizers. Economic status and clinical symptoms were the main factors that contributed to the patterns of antipsychotic prescription. CONCLUSION: The present study suggests that atypical antipsychotic medications, especially clozapine, are the primary psychiatric treatments of choice in the management of schizophrenia in China. Moreover, the economic status and clinical profile of the patient are the major factors affecting the prescription of antipsychotic medication.
