PURPOSE: The goal of this study was to evaluate the impact of life style characteristics on the prevalence risk of metabolic syndrome (MS). METHODS: A total of 581 adults were recruited from a cardiovascular outpatient clinic. A newly developed comprehensive life style evaluation tool for MS patients was used, and patient data related to the MS diagnosis were reviewed from the hospital records. RESULTS: The overall prevalence of MS was 53.2%, and the mean of MS score was 2.6 for patients at a cardiovascular outpatient clinic (78% of the patients had hypertension). Dietary habits among the life style characteristics had significant influence on the prevalence risk of MS and MS scores. And also interestingly, the classification and regression tree (CART) model suggested that the high prevalence risk groups for MS were older adults (61.5< or =age<79.4), and adults between 48.5 and 61.5 yr of age with bad dietary habits. CONCLUSION: This study indicates that nurses should focus on dietary habits of patients (especially patients classified as high prevalence risk for MS) for improvement and prevention of MS prevalence risk.

BACKGROUND: Color Doppler echocardiography is sensitive in detecting mitral regurgitation and useful in quantitating its severity. The presence of an eccentric regurgitant jet suggests that regurgitation is caused by prolapsing or flail leaflet of mitral valve. Until recently the direction of regurgitant jet in mitral valve prolapse has been examined in a single(parasternal short axis view) or orthogonal plane using color Doppler echocardiography, and few in the apical rotation method of a transducer. The purpose of this study was to clarify the usefullness of the apical rotation method of a transducer in detection of the direction of mitral regurgitant jet and diagnosis of the sites of mitral valve prolapse. METHODS: Twenty four patients(8 men and 16 women, mean age:47.3+/-18.8 years) with mitral valve prolapse with eccentric regurgitant jet were examined by two-dimensional and color Doppler echocardiograply using conventional parasternal long and short axis views, and four apical longitudinal planes(four chamber, vertical, two chamber and transverse views) obtained by the apical retation method of a transducer. RESULTS: Thirty one regurgitant jets were detected in twenty four patients, eighteen patients had anterior, nine patints posterior, and three patients bi-leaflet(anterior and posterior) prolapse. In eighteen patients with anterior leaflet prolapse, ten had medial, eight had middle, three had lateral, and three had two portions(two, medial and middle; one, middle and lateral) prolapse. In nine patients with posterior leaflet prolapse, five had medial, three had middle, two had lateral, and one had two(medial and middle) scallop prolapse. CONCLUSION: Color Doppler echocardiography by the apical rotation method of transducer is useful in assessment of the site of prolapse in patients with mitral valve prolapse with eccentric regurgitation.

To detect the cardiac source of embolism in patient of ischemic stroke of uncertain etiology, biplane transesophageal echocardiography and contrast echocardiography with hand-agitated saline were performed 27 patients(sixteen men and eleven women) of transient ischemic attack and cerebral infarction without definitive cardiac symptom and sign. Transesophageal echocardiography showed potential sources of embolism in nineteen patients (70.4%) including atrial septal aneurysm(n = 9, three of them had patent foramen ovale), spontaneous contrast echo(n = 3), mitral valve prolapse(n= 1), unknown thickening of the tip of the mitral valve(n = 1) and atherosclerotic plaque in descending aorta(n = 7). Thus transesophageal echocardiography and contrast echocardiography identify potential cardiac source of embolism, and provide the rationale of the thrombolytic and anticoagulant therapy in patients with ischemic stroke without obvious cardiac disease.

Distortion of vowels in dysarthria associated with amyotrophic lateral sclerosis can be detected at the perceptual, physiological, and acoustical levels of analysis. Sound spectrography was used to analyse the formants of vowels which reflect position and space of articulatory organs. We analyse status and progression of dysarthria in 54 year old women with amyotrophic lateral sclerosis using sound spectrography. Target formant frequencies were measured from select words containing the vowels /a/, /e/, /i/, /o/, /u/. Results revealed that dysarthric patient exhibited smaller vowel space areas and less systematic changes in vowel spaces for pronouncing different vowels in comparison with normal control. Changes of vowel formants in sound spectrographic analysis reflected progression of dysarthric symptom in this patient. We conclude that acoustic analysis of vowels using sound spectrography is a useful tool to visualize and quantitatively analyse the severity and progression of dysarthria due to paralytic articulatory organ.

Single spore isolates of Plasmodiophora brassicae e4 and e9 obtained from diseased Chinese cabbage were identified as race 4 and race 9, respectively, by the Williams' differential variety set. To confirm the possibility of variation in same generation and progeny of a single spore isolate of P. brassicae, random amplified polymorphic DNA (RAPD) analysis was conducted using the URP 3, 6 and OPA 7 primers. There was no difference in band type at each part of the gall of Chinese cabbage obtained by inoculation of e4 and e9 and amplification using the URP 3 and 6 primers when the same generation was analyzed. In addition, the progeny analysis, which was expanded to the third generation and conducted using the URP 3 and OPA 7 primers, revealed no differences in the band type of the e4 isolate. Based on these results, the single spore isolate of P. brassicae was genetically stable.

OBJECT: This study was designed to evaluate the effects of olanzapine on the schedule-induced polydipsia(SIP) which is one of animal model of obsessive-compulsive disorder in rats. We administered olanzapine as a serotonin and dopamine blocking agent, fluoxetine as a selective serotonin reuptake inhibitor, and haloperidol for the dopamine antagonist to rats which showed schedule-induced polydipsic behavior. METHODS: Spraque-Dawley rats weighing 200-250gm were individually housed and maintained and allowed free access to water. The rats were placed on a restricted diet. To induce polydipsia, rats were placed in the cage where a pellet dispenser automatically dispensed 90mg pellets on a fixed-time 60 seconds(FT-60s) feeding schedule over 150 minute test session per day. Water was available at all times in the cage. After 4 weeks of daily exposure to the FT 60s feeding schedule, experimental rats met a predetermined criterion for polydipsic behavior(greater than 3 times of water per session on average). 5 groups of rats were administered olanzapine(3mg/kg, i.p), olanzapine(10mg/kg, i.p), fluoxetine(5mg/kg, i.p.), haloperidol(0.1mg/kg, i.o), and vehicle(1cc/kg, i.p) for 3 weeks. The rats were tested once a week to access schedule induced polydipsic behavior. Water bottles were weighted before and after the 150-minute test session. The chronic effects of administration of experimental drugs on schedule induced polydipsic behavior were analyzed with ANOVA and Scheffe test as a post-hoc comparison. In order to measure water consumption in non-polydipsic food-deprived rats, a separate group of rats(N=8) were individually housed and given a single bolus(14.5gm) of food per day which maintained them at their average body weight. RESULTS AND CONCLUSION: There results were as follows : 1) After 4 weeks of scheduled feeding procedure, the experimental group showed significant differences than the bolus control in the amount of water consumption as compared with their average water intakes for 4 weeks. At the same periods, there were no differences between the experimental group and the bolus control in the body weight. 2) The fluoxetine group showed significant decrease in the amount of water intake over the 3 weeks of drug treatment as compared with their average amount of polydipsic water intakes. The olanzapine 3mg group showed significant decrease in the amount of water intake at 3rd weeks of drug treatment as compared with their average amount of polydipsic water intakes. The olanzapine 10mg group showed significant decrease in the amount of water intake at 2nd and 3rd weeks of drug treatment as compared with their average amount of polydipsic water intakes. However, the haloperidol group and the vehicle control group showed no changes of amounts of water intake for 3 weeks of treatment as compared with their average amount of polydipsic water intakes. 3) The fluoxetine group showed significantly lower amounts of water intake than the haloperidol group at 2nd weeks of drug treatment. And also the fluoxetine group showed significantly lower amounts of water intake than the haloperidol group and the vehicle control at 3rd weeks of drug treatment. The olanzapine 3mg group and the olanzapine 10mg group showed significantly lower amounts of water intake than the haloperidol group and the vehicle control at 3rd weeks of drug treatment. Above findings suggest that the fixed time feeding procedure for schedule-induced polydipsia as an animal model of obsessive compulsive disorder was effective to the evaluation of pharmacological challenge study. The authors assume that the serotonin hypothesis and the serotonin-dopamine interaction hypothesis are preferred to the dopamine hypothesis in the biological etiology of obsessive-compulsive disorder.
