OBJECTIVES: This study was peformed to compare and measure the changes of corpus callosum of the schizophrenic patients with those of controls, to compare according to clinical symptoms, onset age. METHOD: Brain magnetic resonance imaging study was performed in 38 schizophrenic patients and 28 controls, and the authors measured cerebral area, anterior, middle, posterior callosal areas, vertical width, perpendicular width and maximal horizontal callosal length. The schizophrenic patients were assessed by the PANSS. To correct cerebral areas, ANCOVA was used with cerebral areas as covariants. And two-tailed t-test, ANOVA were used to compare callosal measurements according to subgroups. RESULTS: The schizophrenic patients, compared with controls, were significantly wider in posterior callosal area and thinner in anterior vertical width. The schizophrenic patients with prominent positive symptoms were significantly wider and thicker in middle callosal area, anterior middle vertical width than controls, and those with prominent negative symptoms were significantly thinner in posterior vertical width than those with prominent positive symptoms and wider in anterior area than controls. Early onset patients were significantly thicker in middle perpendicular area than controls. CONCLUSIONS: There were various controversial findings about corpus callosal pathology of the schizophrenic patients. This study, after correction of cerebral area, revealed increased sizes of several parts of callosal regions, and then it suggested neurodevelopmental abnormalities. And also significant differences in callosal regions according positive and negative symptoms suggested that these reflected the heterogeneities of schizophrenia.

OBJECTIVE: To assess the impacts of stroke on sexual activities and functioning of patients with stroke and to study the associations of clinical and psychosocial factors with sexual changes following stroke. METHOD: Ninety-seven patients with stroke were interviewed and completed questionnaire concerning their prestroke and poststroke coital frequency, sexual satisfaction, and sexual functions such as erection, ejaculation, and vaginal lubrication. RESULTS: Sexual activities such as coital frequency and sexual satisfaction were decreased in patients after stroke. Sexual dysfunctions including impotence (68%), a decline in ejaculation (66.7%), and a decline in vaginal lubrication (89.5%) were high. Subjective reasons for decreased sexual life after stroke were denial of spouse, impotence, decreased libido, no opportunity of sexual activity due to hospitalization or no sexual partner, fear of relapse, physical discomfort due to hemiparesis and so on. Comparing sexual group with no sexual group after stroke, there were different in age (p=0.040), brain lesion site (p=0.036), prestroke coital frequency (p=0.048), erectile ability (p=0.005), and ejaculation (p<0.001). CONCLUSION: The decline in sexual activities and functioning was due to interpersonal, physical, psychological factors among patients following stroke.

OBJECTIVES: This study was purposed to determine the levels of PCBs and DDE in adipose tissue and serum and to evaluate the relations with factors affecting these levels. METHODS: We analyzed adipose tissues and sera from 52 gynecologic benign disease patients aged 27-78 years, except hormonal diseases such as breast cancer and endometriosis. We also surveyed age, education, occupation, body mass index (BMI), smoking, drinking, number of children, and duration of breastfeeding by questionnaires. Tissue and serum levels of PCBs and DDE were measured using gas chromatography. RESULTS: The median and geometric mean levels of PCBs were 48. 29 ng/g, 56. 78 ng/g for adipose tissue and 4. 67 uc/L, 4. 85 m/L for serum, and those of DDE were 142.89 ng/g, 117.06 ng/g for adipose tissue and l. 75 m/L, 2.09 ua/L for serum, respectively. Adipose tissue and serum levels for DDE showed high correlation (r=0. 310, p=0. 0002), but those of PCBs didn' t (r=0.029, p=0.2582). In analyses of the differences of the means of log transformed adipose tissue and serum PCBs and DDE levels for groups of potential covariates, only adipose tissue DDE levels were significantly associated with number of children (p=0.015), age at first birth (p=0.014) and BMI (p=0.035). In multiple regression analysis, adipose tissue DDE levels were significantly increased with decreasing number of children and increasing age at first birth. CONCLUSIONS: This study suggested that parity and adiposity were associated with levels of DDE in adipose tissue, and adipose tissue is a better biomarker than serum for evaluating the long-term exposure of organochlorines.

BACKGROUND: Nonspecific elevations of CK-MB, cTnT have been well known in patients with chronic renal failure(CRF) on maintenance hemodialysis. It has been suggested that recently developed cTnI seldom shows nonspecific elevations in these patients. Status of CRF patients can be divided into three groups: predialysis group, hemodialysis group and peritoneal dialysis group. Until now, most researchers have studied CK-MB, cTnT and cTnI only in CRF patients receiving maintenance hemodialysis. No previous studies have ever compared the differences of the nonspecific positivity of CK-MB, cTnT and cTnI according to the different status of CRF patients. METHODS: Nonspecific positive ratios of cTnI, cTnT, & CK-MB in were evaluated 20 predialysis patients, 13 CAPD patients and 20 hemodialysis patients. No one had had any evidence of myocardial ischemia during the previous 3 months before the study entry. The predialysis group was again divided into two groups according to the cut off level of serum creatinine of 3.0 mg/dl. Authors also compared the nonspecific positive ratios of cTnI, cTnT, CK-MB between diabetic CRF group and non diabetic CRF group. The sensitivity, specificity and false positive ratios of each enzymes were examined on and 6 hours after arrival in 21 CRF patients who visited the emergency room with the complaint of chest pain. RESULTS: 1) There were no nonspecific significant elevations of cTnI in CRF patients regardless of the status of CRF. But there were significant nonspecific elevations of CK-MB, cTnT in them. It was more marked in cTnT especially with the cut-off value of 0.1 ng/ml. 2) Nonspecific positive ratios of cTnT was significantly increased in diabetic CRF patients. 3) The sensitivity and specificity of cTnI were 100% and 93.3% each, which were significantly higher than those of CK-MB(83.3%, 66.7%) & cTnT(66.7%, 53.3%). CONCLUSION: In CRF patients, the nonspecific positive ratios of CK-MB, cTnT were higher than that of cTnI, and only cTnI did show significant specific elevations in all the CRF patients with acute myocardial infarction. It is likely that the status of CRF patients, dialysis mode, the sampling time point would not give significant changes in the nonspecific positive ratios of CK-MB, cTnT and cTnI.

Pichia ohmeri is a very rare pathogen of human infection. To date, two cases of P. ohmeri infection were reported worldwide. We have experienced a case of catheter-related P. ohmeri fungemia. The patient had been admitted due to cerebrovascular accident in rehabilitation center since August 1998. He had been bedridden due to previous cerebrovascular accident and undergone several episodes of nosocomial infection. Multiple antimicrobial agents had been used with central venous catheter for parenteral nutrition. On February 1999, he had developed fever and dyspnea. Vancomycin and imipenem were administered empirically and central venous catheter was removed on the impression of central venous catheter related infection. Blood culture and catheter tip culture grew P. ohmeri. He developed septic shock and finally led to death before the administration of amphotericin B.

BACKGROUND/AIMS: The serum cytokeratin-18 (CK-18) has been suggested to be a surrogate marker of non-alcoholic fatty liver disease (NAFLD). The aim of this study was to investigate the correlation between CK-18 and metabolic parameter in NAFLD patients. Correlation between CK-18 and macronutrient composition was also assessed. METHODS: A total of 212 subjects were recruited. Blood chemistry including fasting glucose, cholesterol level, AST, ALT, and CK-18 were compared. Data on calorie intake and carbohydrate consumption were acquired by five-day-diet diary using 24 hour recall method. RESULTS: Plasma CK-18 were markedly increased in patient with NAFLD compared with control group (420.4+/-282.3 vs. 313.6+/-179, p<0.001). Plasma CK-18 were positively correlated with systolic blood pressure (r=0.130), ALT (r=0.503) and negatively correlated with HDL cholesterol (r=-0.246). NAFLD patients with metabolic syndrome had higher CK-18 level than those without metabolic syndrome (484.0 vs. 372.1 U/L, p=0.021). When NAFLD patients were subdivided into two groups with CK-18 cut-off value of 400 U/L, patients with CK-18 level over 400 U/L showed higher body mass index (28.0+/-4.5 vs. 25.5+/-4.3), subcutaneous abdominal fat (283.5+/-172.2 vs. 195.7+/-147.8), AST (52.7+/-26.3 vs. 40.7+/-23.5) and ALT (102.0+/-52.6 vs. 61.2+/-32.2). Calorie intake (r=0.301) and carbohydrate intake (r=0.305) also showed positive correlation with CK-18. CONCLUSIONS: Plasma CK-18 showed positive correlation with metabolic parameters as well as calorie and carbohydrate intake when its cut-off value of greater than 400 U/L was used.
