Precise and detailed clinical research and evaluation based on objective standards are imperative factors in securing reliability of a clinical test. Built on this principle, this clinical test has been conducted during the period between March 1999 and March 2000 dealing with 31 outpatients treated with ShiHo-GuizhiTang or ShiHo-GuizhiTang modify and ShiHo-GuizhiTang mixed prescriptions at the Sung-bo ORIENTAL MEDICAL CLINIC. A variety of information relating to those patients has been collected and analyzed under such criteria as precise diagnoses and their clinical effectiveness. The analysis was duly based on "The theory of cold syndrome". Then, the 31 patients' individual clinical information was compared one another by breaking down the results into sub-categories including gender, age, disease, main symptom, blood pressure, pulse beats, syndrome of abdomen, treatment period, modify and mixed prescription, and evaluation. The result of this clinical test can be summarized as follows: First, ShiHo-GuizhiTang appears to be more frequently prescribed in the case of female patients than in the case of male patients despite the fact that it does not necessarily need to be applied only to female. In addition, the numbers of prescriptions of ShiHo-GuizhiTang in the two age groups consisting of elementary school children and economically active adults respectively were the highest among other age groups. Second, ShiHo-GuizhiTang proved to be most effective in treatment for respiratory ailments and arthritis. Third, ShiHo-GuizhiTang brought down blood pressure of hypertension patients and at the same time benefited patients with normal or lower-than-normal blood pressure who were vulnerable to diseases due to low disease-resistance. Fourth, ShiHo-GuizhiTang was effective in the case of frequent pulse(rapid pulse) and thereby indicating the fact it carries Taiyang superficies syndrome. 지맥 arises from suppressed immune responses owing to adrenocortical hormones. ShiHo-GuizhiTang controls and revitalizes those suppressed immune systems which stem from slow pulse and, as a consequence of that process, helps them return to normal condition of pulse. Fifth, from the standpoint of syndrome of abdomen, feeling of obstruction in the epigastrium serves as an important standard in the process of diagnosing diseases and evaluating effectiveness of treatments. Sixth, according to the results of the clinical test with the 31 patients, a total of 81 percent of test subjects benefited from the treatment. The figure is the sum of 52 percent of I-class (both main symptom and accompanying symptoms had been eliminated) and 29 percent of II-class (part of main symptom and accompanying symptoms had been eliminated) respectively. All told it is safe to say that ShiHo-GuizhiTang can elect to be a viable clinical treatment. In conclusion, it is estimated that this clinical study has drawn up guidelines for objective diagnostic standards and evaluation on specific treatments' effectiveness. This will lead to more general application of ShiHo-GuizhiTang. On top of that, this study could also provide an opportunity to stress the significance of ShiHo-GuizhiTang and ShiHo-GuizhiTang modify and ShiHo-GuizhiTang mixed prescriptions as an alternative treatment for collagen disease which comes from environmental degradation and pollution.

The purpose of this study was to investigate the effects of vitamin C supplementation and yoga practice on total antioxidant status (TEAC), lipid peroxidation, and blood lipid profiles of middle-aged women. Thirty two women ($53.34{\pm}5.08$ years old) in B city volunteered and the signed consents were received before the study. Experimental groups were normal (n=8), vitamin C intake group (n=8), yoga group (n=8), and vitamin C intake with yoga group (n=8). Total experimental period was 12 weeks. Yoga group practiced yoga 3 times a week for 12 weeks with intensity of RPE $13{\sim}15$. Each practice was 60 minutes. Vt. C group was instructed to take 1 g of Vt. C every day after dinner meal. Changes in TEAC after 12 weeks were 28.23% for the normal group, 30% for Vt. C group, 26.58% for yoga group, and 43.66% for Vt. C with yoga group; the increases in TEAC among groups were not significantly different. Serum malondialehyde (MDA) concentration of the normal group increased by 10% during 12 weeks of experiment while that for the Vt. C, yoga, and Vt. C with yoga group were significantly decreased by 25%, 32.14%, and 33.87%, respectively (p<0.05) compared with the normal group. Neither yoga, Vt. C supplementation nor combined program for 12 weeks were effective enough to change the serum lipid profiles compared with the normal group. In conclusion, Vitamin C supplementation or regular yoga practice seems to have health promoting effects of retarding the oxidative stress by decreasing lipid peroxidation in middle-aged woman.

This study evaluated the close crop recycling method by using the extract from defective onions. The mixture of the diluted extract (1/500) and nutrients was applied seven times on the onion leaves without spilling it onto the field. The yield and quality of the onions produced by this method (recycle) were compared to those grown organically (control) and conventionally (normal). The yield from the recycling field was increased significantly by 9% compared to that of the control field, while it was decreased by 11% compared to the normal field (p < 0.05). This lower yield was explained by the differences of the mulching vinyl and the fertilizers between the treatments which effect the onion growth during the winter. The content of quercetin in the onions from the recycling filed was increased significantly by 34% and 44% compared to those of the control and normal field, respectively (p < 0.05). It seemed that minerals and biologically active substances in the defective onion extract were effective in increasing the onion growth. In terms of soil microbial biomass, arbuscular mycorrhizal fungi was increased significantly in the recycle field by 40.1% and 30.6% compared to those of the control and normal fields, respectively (p < 0.05). On the other hand, microbial stress (cy19:0/18:1w7c) was decreased in the recycle field by 21.0% and 14.1% compared to those of the control and normal fields, respectively.

This study was performed to investigate the protective effects of acupuncture on the liver in the oxidative stress caused by cadmium accumulation. Sprague-Dawley male($150{\pm}30g$) rats were stabilized for a week and divided into 5 groups which is normal, control, $LR_3$ acupuncture, $BL_{23}$ acupuncture and sham acupuncture group. For three days experimental groups were received oral doses of cadmium 2 mg/kg twice a day. Acupuncture was given bilaterally at each point 10 times for two weeks. The depth of stimulation was 1 mm at right angles and torsion of acupuncture was produced 2 times per second for 1 minutes. The liver was shipped off and taken weight at the last day of two weeks, and hepatic functions was confirmed through alanine transaminase(ALT) and aspartate amino-transferase(AST). We measured reactive oxygen species of serum, liver and kidney, and compared expression levels of superoxide dismutase(SOD), catalase, glutathione peroxidase(Gpx), nuclear factor erythroid derived 2-related factor 2(Nrf-2), heme oxygenase-1(HO-1), nuclear factor-${\kappa}B$ (NF-${\kappa}B$), cyclooxygenase-2(COX-2), inducible nitric oxide synthase(iNOS), Bax and Cytochrome c. $BL_{23}$ acupuncture group significantly increased liver weight and decreased ALT compared to control group. For the oxidative stress, $LR_3$ acupuncture group significantly reduced reactive oxygen species, and $BL_{23}$ acupuncture group significantly reduced reactive oxygen species and inflammation-related protein compared to control group. But $LR_3$ acupuncture group and $BL_{23}$ acupuncture group didn't significantly reduce apoptosis-related protein. Therefore $LR_3$ and $BL_{23}$ acupuncture showed the effects of antioxidant and anti-inflammatory, especially $BL_{23}$ acupuncture was more effective than $LR_3$ acupuncture on the protection of liver in the oxidative stress.

Objectives: The aim of this study was to investigate the correlation between the obesity rate in elementary school students in Daejeon and the relevant factors such as social-demographical factors, genetic factors, birth factors, diet factors and intelligence factors. Methods: For the research, 443 fourth grade students, 405 fifth grade students and 417 sixth grade students from six elementary schools in Daejeon Metropolitan City Participated in this study and classified into three groups: normal-weight group, mild obesity group, and moderate or severe obesity group. Results: The total obesity rate of the elementary school students in the school district of Daejeon Metropolitan City was 14.2%; the rate of mild obesity was 7.2%; the rate of moderate obesity was 5.5%; and the rate of severe obesity was 1.5%. The obesity rate of surveyed boys was 16.9%, and the obesity rate of girls was 11.1%. The significant factors for girls' obesity were fathers' EMI, mothers' EMI, living standards, constant demand of foods, preference for greasy foods, frequency of eating snacks, and daily walking hours. It was found that students' subjective mind and objective health index were related to obesity. In the case of obese students, they had more concern about their health and more stress from the dissatisfaction of their physical appearance than normal students. Conclusions: From the above evidences, it is apparent that the obesity of elementary school students has strong relations with eating habits rather than physical activities. It is to be hoped that obesity prevention programs such as effective meal guidance. parental guidance for watching TV, and intense physical activities will be included in the curriculums of health education for elementary school students.

Objectives : Secondary amenorrhoea is the absence of menses for three months in a woman with previously normal menstruation or nine months for women with a history of oligomenorrhoea. It can be caused by stress, extreme weight loss, and excessive exercise. The purpose of this study was to report the clinical effects of herbal medicine on secondary amenorrhoea.Methods : We employed oriental medical treatments; herbal - medication (Hyunburikyungtang gamibang), acupuncture and moxibustion. We treated the patients one or two times a month with oriental therapy method. They took medicine three times a day after a meal. During taking medicine, we let the patients avoid fatty food, flour based food and alcohol. We evaluated the status of the patient, on the basis of the state of menstration and F2 level of Yangdorak. Because we diagnosed the condition of patients with the pattern of liver depression and qi stagnation, so F2 level of Yangdorak was an important point of the diagnosis. Yangdorak machine was Tormeter Iw - zen at Towatech Co.,Ltd.Results : After taking treatment - several times acupuncture and moxibustion during some period and taking herbal-medicine, they had menstrain naturally without taking any hormone drug. Also the amount of menstration has gradually increased. The F2 level of Yangdorak returned to normal range. The feeling of cold on hands, feet and lower abdomen was much improved.Conclusions : Herbal medicine (Hyunburikyungtang gamibang) with oriental medical treatments, acupuncture and moxibustion was effective in the treatment of secondary amenorrhoea.

BACKGROUND/OBJECTIVES: Red grape seeds as functional food are a good source of important bioactive components such as phenolics and antioxidants, which decrease oxidative stress that contributes to the pathogenesis of hepatotoxicity. The current study was conducted in order to evaluate the protective effect of red grape dried seeds (RGDS) on antioxidant properties, lipid metabolism, and liver and kidney functions of rats with paracetamol (750 mg/kg) induced hepatotoxicity. MATERIALS/METHODS: RGDS was added to the basal diet at 5, 10, and 20%. Thirty five adult male rats were assigned to five groups (n = 7) for a six-week feeding period; group (1) normal control, group (2) induced control, groups (3, 4, and 5) fed a diet with RGPS at different levels, 5, 10, and 20%, respectively. At the end of the feeding period, animals' blood and tissues were collected for estimation of serum lipid profile, serum liver, and kidney biomarkers. The protection was measured by detecting lipid peroxidation (LPO), glutathione (GSH), superoxide dismutase (SOD), Catalase (CAT) (in liver tissues), and liver histological examination. RESULTS: The results showed a significant (P < 0.05) decrease in levels of serum cholesterol, triglycerides, low density lipoprotein (LDL-C), and very low density lipoprotein (VLDL-C), with a significant increase in level of high density lipoprotein (HDL-C) for RGDS groups compared to induced control. Rats administered a diet containing RGDS levels produced significant (P < 0.05) hepatoprotection by decreasing the activities of liver enzymes, kidney parameters, and lipid peroxidation, while levels of GSH, SOD, and CAT were increased significantly to near the normal levels. CONCLUSION: The RGDS 20% group was more effective than others against hepatotoxicity of paracetamol, which may be attributed to RGDS total phenols and antioxidant contents, which were 1.438 mg and 1.231 mg, respectively.

In this study, fatigue crack growth rate of a cracked railway bogie frame under variable amplitude loading is predicted by applying linear elastic fracture mechanics. For this purpose, we find the critical points by reference surveying on cracked railway bogie frames. And we make an effective load history by synthesizing the dynamic load measured from the critical points of railway bogie frame during commercial line operation and the static load calculated from structural analysis. Crack growth analyses are performed at the 3 critical points under the commercial operation loading condition by assuming an initial crack size as 40 mm. and the results are compared with the experimental results from Japanese railway bogie frame crack growth case. From the analysis results, we find that around 500,000 km operating distance is necessary to bring crack growth from the initial crack to unstable crack. And it takes around 3.8 normal operating years. We conclude that it is enough time to detect the crack between normal maintenance period.

Purpose: The purpose of this study was to examine the effects of oral cryotherapy on oral mucositis, reactive oxygen series, inflammatory cytokines, and oral comfort in patients undergoing chemotherapy for gynecologic cancers. Methods: Participants were randomly assigned to the experimental group (n=25, receiving oral cryotherapy during chemotherapy) and the control group (n=25, receiving the usual care consisting of 0.9% normal saline gargles three times before meals). Oral mucositis was assessed using the oral assessment guide, while oral comfort was assessed using the oral perception guide. Reactive oxygen series was measured as total oxidant stress, and the level of two inflammatory markers, interleukin-6 (IL-6) and tumor necrosis factor-alpha ($TNF-{\alpha}$), were examined. The data were analyzed using t-test, chi-square test, Fisher's exact test, Mann-Whitney U-test, and repeated measures analysis of variance. Results: There was a significant difference in the oral mucositis score, reactive oxygen series score, $TNF-{\alpha}$ level, and oral comfort score between the two groups, and there were significant changes over time and in the group-by-time interactions. There was a significant difference in the IL-6 score between the two groups, but there were no significant changes over time or in the group-by-time interactions. Conclusion: The study results revealed that oral cryotherapy was more effective than the usual care regime of normal saline gargles for reducing oral mucositis, reactive oxygen series, and inflammatory cytokines and for improving oral comfort in gynecologic cancer patients undergoing chemotherapy.

This paper proposes a new finite element formulation based on enhanced first-order shear deformation theory including the transverse normal strain effect via the mixed formulation (EFSDTM-TN) for the effective thermo-mechanical analysis of laminated composite structures. The main objective of the EFSDTM-TN is to provide an accurate and efficient solution in describing the thermo-mechanical behavior of laminated composite structures by systematically establishing the relationship between two independent fields (displacement and transverse stress fields) via the mixed formulation. Another key feature is to consider the thermal strain effect without additional unknown variables by introducing a refined transverse displacement field. In the finite element formulation, an eight-node isoparametric plate element is newly developed to implement the advantage of the EFSDTM-TN. Numerical solutions for the thermo-mechanical behavior of laminated composite structures are compared with those available in the open literature to demonstrate the numerical performance of the proposed finite element model.
