Objectives: The purpose of this study was to identify the influence of equality perception and organizational commitment on turnover intention of jobs among psychiatric hospital nurses. Method: Data were collected by questionnaire survey among 158 nurses working in 10 psychiatric hospitals from August 1st to September 30th. 2004. Results: The degree of turnover intention of jobs was significantly different by marital status, religion, qualification of psychiatric specialized nursing, monthly income and the location of hospitals. The correlation analysis showed that the turnover intention of jobs decreased as the equality perception and the organizational commitment increased. The hierachical multiple regression analysis showed that significantly related variables with turnover intention of jobs were religion, monthly income, equality perception and organizational commitment. The model explanation power was 53.1%. Conclusion: Because the equality perception explained 53.1% of variance of turnover intention among psychiatric nurses and organizational commitment was related with the turnover intention of nurses at psychiatric hospitals, activation strategy of organization must include the promotion strategy of equality perception and organizational commitment to decrease turnover intention of jobs among nurses.

Steroid acne and pityrosporum folliculitis have similar clinical manifestations. So it was not casy to do differential diagnosis of these two diseases. We have tried to find out the different points between these diseases in clinical characteristics, positive rate of the malassezia spores, and their response to antifungal agents. We studied 21 patients with acneiform eruptions which were distinct from acne vulgaris. Patients were divided into two groups by steroid treatment history. Among 21 patients, 6 were administered steroid just before eruption and 15 were free from steroid within 6 months. We have examined malassezia spores with 10% KOH/Parker blue black ink mount from papules, pustules and comedones according to the patients skin lesions. The malassezia spores detected in 5 paticnts(83.3%) in the former and 9 patients(60%) in the latter. In malassezia folliculitis, the frequency of which showed above the (3+) score of malassezia spore under microscopy was higher than in steroid acne. Mean duration of the disease was 70.4 weeks in latter group, which was longer than 5.2 weeks of the former group. And there were some differences between two groups in the distribution of the lesions. Mean treatment duration was same in two groups (4 wks, 3.5 wks). Steroid acne patients would be treated better with antifungal agents than with acne regimens.

Cytogenetic effects of radiation exposure and ionic contrast media were evaluated in peripheral lymphocytes. Accentric chromosome fragments produced n cells by radiation exposure or othe agents give rise to imcronuclei in daughter cells. The micronuclei could be counted readily in larger number of cell which provided a sensitive measure of radiation exposure and contrast media induced chromosome aberration. Radiation exposure and contrast media induced microunclei formations in human lymphocytes were counted in vitro and in vivo. Results were as follows: 1. Micronuclei in lymphocytes were produced by exposure to contrast media and/or radiation. 2. Numbers of micronuclei formation in peripheral lymphocytes after enhanced CT were more increased than inert condition. 3. Lymphocytes of micronuclei formation were increased in number of the plate prepared with contrast media only, but the number of lymphocyte of microniclei formation was not proportional to the concentration of contrast media. 4. The number of lymphocytes of radiation exposure and contrast media induced micronuclei formation was increased than te preparation with contrast media only. 5. The number of lymphocyte of radiation exposure and contrast media induced micronuclei formation in vitro was more increased than enhanced CT in vivo.

The effect of cadmium ?? on the [³H] quinuclidinyl benzilate (QNB) binding of the muscarinic receptors in the cerebrum was examined. ?? Inhibited [³H]QNB binding in both dose-dependent and time-dependent manners and this inhibitory action was irreversible. The ?? Value of ?? to inhibit [³H]QNB binding in the presence of 100 pM [³H]QNB in the cerebral microsome pretreated with ?? at 37℃ for 15 min was about 50㎛. The inhibition of [³H]QNB binding by 50㎛ ?? followed biphasic kinetics ; there is a rapid inhibition phase during first 10 min incubation periods and a slow inhibition phase after a rapid phase. ?? decreased the binding site concentration for [³H]QNB binding without affecting the affinity of QNB. These results suggest that sulphydryl group plays an important role to maintain the muscarinic receptor conformation for [³H]QNB binding.

The purpose of this study was to evaluate the elastic memory process in cold worked stainless steel wire and the effect of heat treatment on it. 0.018 inch round and 0.019×0.025 inch rectangular wire(ORMCO stainless wire) were used in this study. Each wire type had 4 groups: non-heat treatment group, furnace heat treatment group, electric current heat treatment group, and bending after heat treatment group. Each group was consisted of 10 specimens. With the Jig, each wire was bent into v-shape uniformly, and width of two free ends of each v-shape wire was measured by caliper (to the point of 0.1㎜ correctly) at time interval of off-jig, after heat treatment, 1,2,3,4 hours, 1,2,3,4,5,6 days, 1,2,3,4 weeks after. The results were as follows; 1. In non-heat treatment group and bending after heat treatment group, elastic memory process was occured 60% within 1 hour, and more than 90% within 1 week. 2. In furnace and electric current heat treatment group, almost all elastic memory process was occured during heat treatment, and then specimen was stabilized dimensionally. 3. Magnitude of deformation by elastic memory was greater in heat treatment group than non heat treatment group and bending after hear treatment group. 4. There was no remarkable difference in deformation pattern between 0.018 inch round wire and 0.019×0.025 inch rectangular wire.

Objectives : This open prospective study was performed in order to evaluate the efficacy and extrapyramidal adverse effects of nemonapride in the schizophrenic patients, and was compared wit one of typical antipshchotics. haloperidol and one of atypical antipsychotics, risperidone. Methods : Thirty male and female schizophrenic patients(DSM-Ⅳ) were treated for 12 weeks with haloperidol(n=10), risperidone(n=10) and nemonapride(n=10). The overall efficacy was assessed at baseline, 1st week, 2nd week, 4th week, 8th week, and 12th week by the Positive and Negative Syndrome Scale for Schizophrenia(PANSS). Also the overall safety was assessed in the same time period by the Extrapyramidal Symptom Rating Scale(ESRS). Results : There were no significant differences in PANSS scores(total, positive, negative, and general psycho­pathology subscale) among haloperidol, risperidone, and nemonapride groups, Treatment responders, defined as at least 20% reduction of baseline total PANSS score, were achieved by 8 patients(80%) in haloperidol group, 10 patients(100%) in risperidone group, and 8 patients(80%) in nemonapride group. And there were no significant differences in ESRS total scores among haloperidol, risperidone, and nemonapride group. Inter-group comparison among haloperidol, risperidone and nemonapride group, as assessed by the ESRS, revealed no significant differences in the shifts to the maximum score, 9.4(±9.4), 6.2(±8.4), and 11.3(±8.1) respectively, and also revealed no significant differences in the mean time reaching the maximum score, 4.5(±4.5) week, 7.8(±4.8) week, and 4.6(±4.4) week, respectivily. Conclusion : There wee no significant differences in the efficacy and extrapyramidal adverse effects among haloperidal, rispecridone and nemonapride groups. These results suggest that nemonapride was as efficacious and safe in he treatment of schizophrenia, as well known and widely used antipsychotics, haloperidol and risperidone.

The muscarinic antagonist l-[benzilic-4, 4'-³H]quinuclidinyl benzilate([³H]QNB) bound to a single class of muscarinic receptor with high affinity in guinea pig ileal membranes. The K_(D) and B_(max) values for [³H]QNB calculated from analysis of saturation isotherms were 54 pM and 156 fmol/mg, respectively. H₁-blockers inhibited [³H]QNB binding to ileal membranes with K_(i) values ranged from 0.008 μM to 1.6 μM. The pseudo-Hill coefficients of H₁-blockers for inhibition of [³H]QNB binding to the ileal membranes were close to unit. The K_(i) values for H₁-blockers were similar to the K_(M) values calculated by Schild plot of functional data obtained from inhibition of the carbachol-induced contraction in guinea-pig ileum, suggesting that binding of H₁-blockers vs [³H]QNB in ileal membranes represents an interaction with a receptor of physiological relevance. The K_(H) values of H₁-blockers for H₁-receptor estimated from inhibition of the histamine-induced contraction were the range of 0.15 nM to 56.5 nM. The K_(M)/K_(H) ratio of H₁-blockers varied over a wide range of 3 to 2300. Thus, the antihistaminic potencies of H₁-blockers do not correlate with their antimuscarinic potencies, which suggest that antihistamines have different antimuscarinic potencies in therapeutic blood levels causing similar antiallergic effect. Among 13 traditional antihistaminics examined in this study, drug having the highest and the lowest K_(M)/K_(H) ratio is triprolidine and diphenidol, respectively. The present results demonstrate that the antimuscarinic property of antihistamines is not necessary for their antiallergic effect, and data on the affinity of antihistamines for muscarinic and H₁-receptors can be an important parameter in the selection and evaluation of these drugs.
