An Angiotensin I Converting Enzyme Polymorphism Is Associated with Clinical Phenotype When Using Differentiation-Syndrome to Categorize Korean Bronchial Asthma Patients
In this study, genetic analysis was conducted to investigate the association of angiotensin I converting enzyme (ACE) gene polymorphism with clinical phenotype based on differentiation-syndrome of bronchial asthma patients. Differentiation-syndrome is a traditional Korean medicine (TKM) theory in which patients are classified into a Deficiency Syndrome Group (DSG) and an Excess Syndrome Group (ESG) according to their symptomatic classification. For this study, 110 participants were evaluated by pulmonary function test. Among them, 39 patients were excluded because they refused genotyping. Of the remaining patients, 52 with DSG of asthma (DSGA) and 29 with ESG of asthma (ESGA), as determined by the differentiation-syndrome techniques were assessed by genetic analysis. ACE insertion/deletion (I/D) polymorphism analysis was conducted using polymerase chain reaction (PCR). Student's t, chi-square, Fisher and Hardy-Weinberg equilibrium tests were used to compare groups. No significant differences in pulmonary function were observed between DSGA and ESGA. The genotypic frequency of ACE I/D polymorphism was found to differ slightly between DSGA and ESGA (P = .0495). However, there were no significant differences in allelic frequency observed between DSGA and ESGA (P = .7006, OR = 1.1223). Interestingly, the allelic (P = .0043, OR = 3.4545) and genotypic (P = .0126) frequencies of the ACE I/D polymorphism in female patients differed significantly between DSGA and ESGA. Taken together, the results presented here indicate that the symptomatic classification of DSGA and ESGA by differentiation-syndrome in Korean asthma patients could be useful in evaluation of the pathogenesis of bronchial asthma
Antioxidant Effect of Bee Venom Herbal Acupuncture
Bee venom has been clinically used to control the pain of inflammation disease etc. in general. Although the effect of bee venom herbal acupuncture has been reported, its mechanism has not been fully elucidated yet. Free radical metabolism seems to occupy a remarkably common position in the mechanisms of inflammation and ageing related disease. Oxidative damage to DNA, lipids, proteins and other molecules may contribute to the development inflammation disease. NO or DPPH is one of the free radicals and a mediator in inflammation diseases. The objective of this study is to investigate the scavenging effect of bee venom herbal acupuncture against NO and DPPH.
The followings are the summary of the results: (1) There is no significant scavenging effect of bee venom herbal acupuncture on NO in BVS and BVP group. (2) There is a significant scavenging effect of bee venom herbal acupuncture on DPPH in BVS-1 and BVP-1 group. These results suggest that bee venom herbal acupuncture can be used for inflammation diseases such as rheumatoid arthritis. This study would provide important basic data on the possibility of the clinical treatment of bee venom herbal acupuncture. Further studies are required to investigate the antioxidative effects of it
Qigong program on insomnia and stress in cancer patients: A case series report
Background: In recent years, the interest in Qigong as an alternative therapy has grown following reports of its ability to regulate psychological factors in cancer patients. This is a case series to evaluate the outcome measures of Qigong when used as an adjunct to standard medical care to treat insomnia and stress in cancer patients. Patients and methods: The Qigong program was applied to four cancer patients with insomnia, stress, and anxiety. The program consisted of 30-min sessions involving exercise, patting of the 12 meridians, and spontaneous breathing exercises three times a week for a period of 4 weeks. The Pittsburgh Sleep Quality Index was measured as the primary outcome, while the Stress Scale, the State–Trait Anxiety Inventory, and the Functional Assessment Cancer Therapy–General determined the secondary outcomes. Insomnia, stress, and anxiety levels were examined weekly, while quality of life was examined on the first visit and the last visit. Results: The Pittsburgh Sleep Quality Index and Stress Scale scores were reduced after conduct of the Qigong program. Conclusion: This study could provide a better understanding of Qigong’s influence on insomnia and stress in cancer patients. However, a larger controlled trial should be conducted to confirm these findings
Analytic approach to analyzing the performance of membrane dehumidification by pervaporation
As life quality has been greatly improved recently, the importance of humidity control has increased. Various kinds of humidifiers and dehumidifiers have been developed and utilized widely in our daily lives and industrial processes. In this work, we focused on dehumidification facilitated by a pervaporation system that employs a nonporous membrane. The system mainly consists of two parallel chambers separated by the membrane and a vacuum pump that constantly drives moisture removal. The membrane-pump couple sets out a vapor concentration gradient across the membrane to permeate water vapors from the feed chamber of ambient wet air to the low-pressure permeate. The experiments were performed in a constant temperature and humidity chamber to supply the constant concentration of vapor to the feed chamber. We measured the outlet humidity and the water vapor transport rate, the mass of vapor permeated through the membrane, under various experimental conditions of different feed flow rates and feed chamber heights. As the flow rate increases, the outlet humidity is decreased, whereas the water vapor transport rate is increased. However, they are independent of the height in our experiment range. Combining the mass transport theory of the membrane and volume conservation of an infinitesimal control volume, we have established theories of the outlet humidity and the water vapor transport rate. The experimental data points are entirely consistent with our theory curves. Comparing the experimental results to the theories, we also have derived the membrane coefficient.11Nsciescopuskc
