Plasma levels of plasminogen activator inhibitor 1 （PAl-l） modulate this risk. A deletion/insertion polymorphism within the PAl-1 loci （4G/4G, 4G/5G, 5G/5G） affects the expression of this gene. The present study investigated the association between PAl-1 loci polymorphisms and HTN in Korean women. Methods Korean women （n=1312） were enrolled in this study to evaluate the association between PAl-1 4G/5G gene polymorphisms and HTN as well as other metabolic risk factors. PAl-1 loci polymorphisms were investigated using polymerase chain reaction amplification and single-strand conformation polymorphism analysis. Results The three genotype groups differed with respect to systolic blood pressure （P=0.043）, and diastolic blood pressure （P=0.009） but not with respect to age, body mass index, total cholesterol, low or high density lipoprotein cholesterol, triglycerides, or fasting blood glucose. Carriers of the PAl-1 4G allele had more hypertension significantly （PAl-1 4G/5G vs. PAl-1 5G/5G, P=0.032; PAl-1 4G/4G vs. PAl-1 5G/5G, P=0.034）. When stratified according to PAl-1 4G/5G polymorphism, there was no significant difference in all metabolic parameters among PAl-1 genotype groups in patients with HTN as well as subjects with normal blood pressure. The estimated odds ratio of the 4G/4G genotype and 4G/5G for HTN was 1.7 （P=0.005）, and 1.6 （P=0.015）, respectively. Conclusion These findings might indicate that PAl-1 loci polymorphisms independently contribute to HTN and that gene-environmental interaction may be not associated in Korean women.展开更多

Various supplements and nutraceuticals for relieving of fatigue have been used. However, there are a few studies to evaluate the efficacy and the safety of the drug tbr fatigue alleviation, we conducted using URSA Complex to evaluate the efficacy on physical fatigue via score changes in the checklist individual strength （CIS）. Methods： The study was designed as a multicenter, randomized, double-blind, placebo-controlled trial, with subjects randomized to one of the two arms, receiving either placebo or URSA Complex administered as identical capsules. The primary efficacy endpoints of this clinical trials are the ratio of improving CIS scores 〈 76 points in patients at the end （4 weeks）. Secondary efficacy variables are as follows one is an improvement of fatigue and the other is an improvement of the liver enzyme. Results： The fatigue recovery rate in who had improved CIS scores of 〈 76 points were 70.0%, 50.9% in the therapy group and placebo group, respectively （P = 0.0l 9）. The fatigue recovery rate in CIS score was higher in URSA Complex therapy group than placebo group. The difference between therapy group and placebo group was statistically significant at 4 weeks later, but not 2 weeks. Conclusions： Our results provided that the URSA Complex was effective in alleviating physical fatigue. The adverse event frequency in the therapy groups was similar to that in the placebo group.展开更多
