BACKGROUND: Although current dietary guidelines recommend to increase the consumption of whole grain, these recommendations are mainly derived from the belief that replacing fats with carbohydrate may reduce risk of coronary artery disease (CAD) by improving serum lipids. Our objective was to evaluate whether the isocalorical replacement of refined rice with whole grain reduce CAD risk factors such as insulin demand and lipid peroxidation in CAD patients. METHODS: Thirty-eight male patients with CAD were provided with 70 g powder of whole grain (220 kcal) for 16 weeks, replacing cooked refined rice as a carbohydrate source of breakfast. An oral glucose tolerance test (OGTT) was performed in all subjects to determine the effect of whole grain consumption on serum concentrations of insulin and glucose in CAD patients with different degree of glucose tolerance. RESULTS: With the substitution of whole grain for refined rice, serum glucose concentrations decreased by 24% without altering body weight and energy intake. Estimates of daily fiber and vitamin E intakes increased by 24% and 50%, respectively. Whole grain consumption in CAD patients without diabetes decreased fasting glucose (22%) and the area under the curve (AUC) for insulin (26%) and glucose (19%) during an OGTT. CAD patients with diabetes also showed reductions in fasting glucose (27%) and AUC for glucose (25%) during the OGTT, compared with baseline values. Whole grain consumption reduced plasma malondialdehyde and homocysteine and urinary 8-epi-prostaglandin F 2alpha concentrations by about 30%. Lipid-corrected concentrations of alpha-carotene, retinol, alpha- and gamma-tocopherol and lycopene increased by 22-46%, compared with baseline values. Whole grain consumption decreased the percentage composition of w6 fatty acids of serum phospholipid increased by 14%. CONCLUSION: The replacement of refined rice with whole grain as a carbohydrate source of a meal showed significant beneficial effects on glucose, insulin and homocysteine concentrations and lipid peroxidation in CAD patients. These effects are likely to substantially reduce the risk factors of CAD and diabetes in CAD patients.

The purpose of this study was to investigate the pattern of individual fatty acid intake and to compare serum lipid levels and total serum fatty acid composition of high school students in Seoul (total:234;male:91;female:143). In serum lipid levels, total cholesterol (Chol.), HDL -Chol. and LDL-Chol. levels of female students were significantly higher than those of male students and there was no significant difference between High Fish & Low Meat intake (HFLM) and Low Fish & High Meat intake (LFHM) groups. The average fat intake was 22 - 25 energy % of total subjects and especially, that of LFHM group was 29%, which were over the recommendation level. Although the average P/M/S ratio of dietary fat was 1.1/1.2/1.0, the average range of omega 6/omega 3 fatty acid ratio of dietary fat was found to be 17.9 - 20.7, which was far beyond the suggested range, 4 - 10. The average intake of cholesterol of total subjects was 360mg. LFHM group had more meats and beverages such as carbonated drinks and tended to have less beans, vegetables and mushrooms. In addition, LFHM group had more energy and fat intake than those of HFLM group, the P/S ratio of dietary fat (0.73) was lower than the recommended ratio. Serum C16:0 composition of LFHM group was significantly higher than that of HFLM group, and EPA and DHA composition of HFLM was significantly lower than that of LFHM. Therefore, in HFLM group, the P/S ratio of serum fatty acids was significantly higher and the omega 6/omega 3 ratio was lower. Dietary C18: 0 was negatively correlated with serum EPA and DHA composition. Individual PUFA intake was negatively correlated with serum C16:0 and sum of SFA, and positively correlated with serum C18:2omega 6 (LA), sum of omega 6 and sum of PUFA. Serum C18:1, C18:3omega 3 and C20:4omega 6 (AA) compositions were not correlated with dietary fatty acid. Only serum triglyceride (TG) levels were significantly correlated with serum fatty acid compositions. Sum of SFA, C14:0, C16:0, sum of MUFA and C18:1 compositions were positively correlated with serum TG levels, but LA, AA, sum of PUFA and P/S ratio were negatively correlated with it.

PURPOSE: Growing data on the relationship between cytokine expression and the progression of renal diseases make these cytokines potential targets for therapeutic interventions. Weexamined the helper T1-cell- and macrophage-associated cytokines in anti-glomerular basement membrane (GBM) antibody-induced nephritis in mice and their temporal relationships with renal tissue fibrosis. METHODS: Kidneys were harvested on days 1, 3, 7, 11, and 16 after glomerulonephritis was induced with anti-GBM antibody. The progression of renal fibrosis was serially monitored to quantitate the accumulation of cortical extracellular matrix, and various cytokines were measured simultaneously. RESULTS: A single injection of anti-GBM antibody successfully produced severe crescentic glomerulonephritis. Proteinuria increased abruptly and both mesangial matrix expansion and interstitial fibrosis progressed rapidly. Cortical fibronectin and type III collagen increased continuously, reaching a peak on day 7, and the deposition of type III collagen followed the same pattern, in parallel with that of urinary transforming growth factor 1 (TGF-1) expression. Serial cytokine measurements revealed a sustained increase in interleukin (IL) 6 and monocyte chemoattractant protein 1 (MCP1) from day 3, but neither IL12, IL18, nor interferon changed significantly. Real-time polymerase chain reaction confirmed these features at the transcription level. CONCLUSION: MCP1 and IL6 correlated with the progression of renal fibrosis, with no increase in Th1- inducing cytokines. This confirms MCP1 and IL6 as attractive therapeutic targets for renal fibrosis in crescentic glomerulonephritis.

This study was conducted to evaluate changes in plasma concentration and urinary excretion of carnitine, as well as plasma lipid level and fatty acid composition, caused by short term supplementation of carnitine in humans. Ten healthy male subjects (21.2 +/- 0.5 years old) received oral carnitine supplementation (4 g/day) as tablets for two weeks. Fasting blood and random urine samples were collected from each subject both prior to and at the end of carnitine supplemention program. Following the 2 weeks of carnitine supplementation, plasma total carnitine (TCNE) concentration increased 20% (85.1 +/- 7.4 vs 67.3 +/- 9.1 micro mol/1, p>0.05), while urinary excretion of total carnitine increased ten times compared to the value measured prior to the supplementation (3051 +/- 692 vs 278 +/- 90.1 micro mol/g creatinine, p<0.01). Non-esterified carnitine (NEC) comprised from 71 to 88% of TCNE in plasma, and from 32 to 40% of TCNE excreted in the urine. Two weeks of carnitine supplementation in healthy adults significantly elevated plasma level of acid soluble acylcarnitine (ASAC) which is esterified mostly with short chain fatty acids (21.6 +/- 1.6 micro mol/l) compared to the value measured prior to the supplementation (6.4 +/- 0.8 micro mol/l) (p<0.05). Carnitine supplementation significantly increased plasma HDL-cholesterol level (p<0.05), and decreased the atherogenic index (p<0.05), but failed to cause any significant change in plasma levels of total cholesterol, triglyceride, and free fatty acids. Plasma triglyceride and phospholipid fatty acid compositions were not significaly affected as well by the oral supplementation of carnitine in subjects with normal range of blood lipid levels.

Both diabetic retinopathy (DR) and coronary heart disease (CHD) are clinically significant in diabetic patients. We investigated the correlation between the severity of DR and the presence and severity of CHD among type 2 diabetic patients. A total of 175 patients who were examined at the DR clinic and underwent dual-source computed tomography (DSCT) angiography within 6 months were included. The degree of DR was graded as no DR, nonproliferative DR (NPDR), and proliferative DR (PDR). The severity of CHD and the numbers of significant stenotic coronary artery on DSCT angiography according to DR grade were assessed. The mean Agatston Calcium Score (ACS) in patients with PDR was significantly higher than other groups (P < 0.001). The overall odds of an ACS increase were about 4.7-fold higher in PDR group than in no DR group (P < 0.001). In PDR group, in comparison with in no DR, the odds of having 1 or 2 arterial involvement were 3-fold higher (P = 0.044), and those of having 3 were 17-fold higher (P = 0.011). The c-index, one of the predictability values in regression analysis model, was not significantly increased when PDR was added to classical CHD risk factors (0.671 to 0.706, P = 0.111). Conclusively, patients with PDR develop a greater likelihood of not only having CHD, but being more severe nature. PDR has no additional effect to classical CHD risk factors for predicting CHD.

The development of a prophylactic vaccine that targets human papillomaviruses (HPV) 6, 11, 16, and 18 to prevent cervical cancer has increased interest in the ethnic and geographical distributions of HPV genotypes. We investigated HPV prevalence and type distribution by restriction fragment mass polymorphism (RFMP) testing a total of 60,775 specimens (aged 18-79 yr, median 44) taken from liquid-based cytology. Overall HPV positive rate of total patients was 34.2%. Among the positive patients, 87.7% was single type infections, and 12.3% was multiple HPV types. HPV-16 was the most prevalent genotype observed in 2,307 (26.0%), followed by type 52 in 2,269 (25.5%), type 58 in 1,090 (12.3%), type 18 in 633 (7.1%), type 56 in 436 (4.9%). The pattern of high risk-HPV positive rate according to age showed U-shape with a peak in HPV prevalence among women less than 30 yr of age, and a second peak among the older females aged 70 to 79 yr. The leading four high-risk HPV genotypes were HPV-16, HPV-52, HPV-58, and HPV-18 in descending order. In conclusion, this study provides the most representative prevalence and type-specific distribution of HPV among Korean women, and demonstrates that the epidemiology of HPV infection is different from that of other regions of the world.

OBJECTIVE: The present study aimed to evaluate the efficacy of low frequency (LF) repetitive transcranial magnetic stimulation (rTMS) over the right dorsolateral prefrontal cortex (DLPFC) for the treatment of obsessive-compulsive disorder (OCD). METHODS: Twenty-seven patients with treatment resistant OCD were randomly assigned to 3 week either active (n=14) or sham (n=13) rTMS. The active rTMS parameters consisted of 1 Hz, 20-minute trains (1,200 pulses/day) at 100% of the resting motor threshold (MT). OCD symptoms, mood, and anxiety were assessed at baseline and every week throughout the treatment period. RESULTS: A repeated-measures analysis of variance (ANOVA) was used to evaluate changes on the Yale-Brown Obsessive Compulsive Scale (YBOCS). Our results revealed a significant reduction in YBOCS scores in the active group compared with the sham group after 3 weeks. Similarly, a repeated-measures ANOVA revealed significant effect of time and time×group interaction on scores on the Hamilton Depression Rating Scale and the Clinical Global Impression-Severity scale. There were no reports of any serious adverse effects following the active and sham rTMS treatments. CONCLUSION: LF rTMS over the right DLPFC appeared to be superior to sham rTMS for relieving OCD symptoms and depression in patients with treatment-resistant OCD. Further trials with larger sample sizes should be conducted to confirm the present findings.

BACKGROUND: Pyelonephritis is one of the major causes of chronic renal failure in children, and the transforming growth factor-beta1 (TGF-beta1) is a molecule with pivotal roles in fibrogenesis. This study was performed to investigate the alteration and clinical implications of urinary TGF-beta1/creatinine ratio in children with acute pyelonephritis. METHODS: Urine was collected from 67 normal children and 25 children with acute pyelonephritis. After routine urinalysis, urine TGF-beta1 was quantitated by ELISA method and creatinine was measured by alkaline picrate method. Urinary TGF-beta1/ creatinine ratios in children with pyelonephritis were compared with those of age-matched controls, and sequential changes of the ratios in pyelonephritic children were traced after antibiotic treatment. Correlation of urinary TGF-beta1/creatinine ratio with the degree of pyuria and renal scar was analyzed each. RESULTS: Neonates showed higher urinary TGF-beta1/creatinine ratios than older children. The ratio increased in acute pyelonephritis and gradually returned to the control level two days after antibiotic treatment. Urinary TGF-beta1/creatinine ratio in acute pyelonephritis was not correlated with the degree of pyuria and renal scar. CONCLUSION: The age should be considered in evaluation of urinary TGF-beta1/creatinine ratio in children. The ratio increases in acute pyelonephritis, and is independent of the degree of pyuria or renal scarring.
