  • After infection of male mice with the plerocercoids (spargana) of Spirometra mansoni, serum levels of estrogen and testicular weight were analyzed by enzyme-linked immunosorbent assay (ELISA) and weighing machine, respectively. The serum level of estrogen increased progressively in infected mice compared with normal controls, whereas the testicular weight of infected mice decreased significantly (P < 0.05). These results suggest that certain substances from spargana change the steroid hormone metabolisms in the host by unknown pathways, and chronic infection may contribute to change of the function of steroid hormone target organ, i.e., testis, in male mice.

  • The change in bodyweight, organ weight and the amount of water intake were investigated to assess the effect on a range of toxicological parameters of varying dosages of polyacetylene compounds. Concerning inhibition of solid tumor growth induced by Sarcoma-180 cells in the ICR mouse strain, relytionships between the dosage of polyacetylene compoilnds used and several toxicological parameters were observed. When 40μmoles/kg b.w. of panaxydol tvas administered for 3 consecutive days, the suppression of body weight growth in Wistar rats was about 17% that of the control group, however, the body weight gain was normalized 4 days after stopping arlnlinistration of the polyacetylene compounds. When the dosage of polyacetylenes was reduced to 20μmoles/kg b.w., the change in body weight gain was alleviated to within l0% of the control and the suppremission of the body weight gain increased in order for Panaxydol, Panaxynol, and Panaxytriol. The organ weight did not show any significant change between the control and the polyacetylene administered groups. Electron micrographs of the liver tissues of ICR mice injected with 40Umoles/kg b.w. of panaxydol gave no further significant information about toxicological changes. Keywords Polyacrtylenes, toxicological parameters, body weight, panaxydol, organ weight, electron micrographs .

  • Plant-based cultural assets using straw and grass as household goods of our people's have been used as indispensable tools for practical living for a very long time. However, only a limited number of artifacts were unearthed so far due to tile fragility of the material. For this reason, research on plant-based cultural properties had close to no progress, and the appropriateness of the PEG method, high-grade alcohol method, alcohol--ether-resin method, and Paraloid B-72 used in preserving plant-based cultural properties has not been sufficiently investigated. Therefore, this study examined the weight change rate by applying the methods of Primal MC-76 and vacuum freeze-drying used mostly as a earth-layer hardening material among PEG and acrylic resin, which are applied widely for preservation of waterlogged archaeological wood, as a means to preserve plant-based cultural properties along with the examination of the subject material, and an experiment was also performed on moisture absorption. The findings as a result were, first, the plant-based material being studied was found to be Typha (Typha orientalis Presl). Secondly, the weight change experiment applying $PEG\#400$ and $PEG\#4000$ confirmed a steady increase of weight if PEG -2Step is used for treatment. Third, in preserving all subject materials with soil, treatment with $PEG\#4000$, Primal MC-76, and vacuum freeze-drying showed that tile vacuum freeze-drying method resulted in the largest or $20\%$ reduction in weight, while Primal MC-76 resulted in $18\%$ and $PEG\#4000$ in $8\%$ of weight reduction. It was concluded that, considering the stability of soil measurement, this came to be because resin permeation was carried out along with tile drying process. Fourth, the weight changes were found to be around $10\%$ in various humidity conditions after the preservation treatment. The greatest weight change rate was seen in the case of $PEG\#4000$, particularly having chemicals gush out in a high humidity (RH $84\%$ or higher) environment. In the case of Primal MC-76 and vacuum freeze-drying methods, $6\~8\%$ weight changes were detected, and the lowest weight change was found in the case of the vacuum freeze-drying method. Fifth, as for color changes after treatment, blackening occurred most strongly with $PEG\#4000$, while Primal MC-76 and vacuum freeze-drying manifested colors closest to dry straw or grass. However, the texture of straw was not very evident in the case of Primal MC-76, due to a glossy surface, but vacuum freeze-drying was found to offer tile best result in terms of texture. Putting together the results of the above experiments, vacuum freeze-drying presented after being treated with PEG2-Step the most stabilized changes in weight, while it offered the smallest change in color as well.

  • The color changing of the wood surface was tested by accelerated weathering test that can simulate the outdoor condition with short period. In early parts of accelerated weathering test, weight and volume of specimen all were increased due to the moisture evaporation by its high temperature and illumination level, but weight and volume of specimen all were decreased from middle parts to last. However, significancy showed between control group and accelerated weathering test group in terms of weight and volume. According to the results of color-difference meter, in the early parts of the accelerated weathering test lightness, redness and yellowness all showed a clear increasing or decreasing trend. However, after three weeks all values were almost never change. Until the early parts of the test, lightness was decreased and there was not a considerable change after three weeks in the test. Redness showed a some change in early parts of the test, but this also showed not great change after middle parts of the test as like lightness. Yellowness also showed same pattern. These results could be verified through the visual inspection. As like weight and volume, significancy showed between control group and accelerated weathering test group in terms of color-difference test. In all accelerated weathering test group, color-differences of after test was lower than that of before test. To correctly analyze this cause, more additional research will be need on each of temperature, humidity and illumination factors.

  • In this study, the effect of supplementary materials(GGBS, PFA, SF) on sulfuric acid corrosion resistance was assessed by measuring the compressive strength, corroded depth and weight change at 7, 28, 56, 91, 180 and 250 days of immersion in sulfuric acid solution with the pH of 0.5, 1.0, 2.0 and 3.0. Then, it was found that an increase in the duration of immersion and a decrease in the pH, as expected, resulted in a more severe corrosion irrespective of binders: increased corroded depth and weight change, and lowered the compressive strength. 60% GGBS mortar specimen was the most resistant to acid corrosion in terms of the corroded depth, weight change and compressive strength, due to the latent hydraulic characteristics and lower portion of calcium hydroxide. The order of resistance to acid was 60% GGBS>20% PFA>10% SF>OPC. In a microscopic examination, it was found that acid corrosion of cement matrix produced gypsum, as a result of decomposition of hydration products, which may loose the structure of cement matrix, thereby leading to a remarkable decrease of concrete properties.

  • Purpose: The purpose of this study was to identify the level of body perception, obesity, and factors associated with stages of exercise and dietary habits change in university students. Methods: A descriptive design was used. Data were collected from 279 university students using structured questionnaires. Results: The body perception was significantly associated with self rated health (F=27.89. p<.001), weight satisfaction (F=137.74. p<.001) and weight control interest (F=39.19. p<.001). The BMI was significantly associated with weight satisfaction (F=34.08. p<.001) and weight control interest (F=19.59. p=.003). But the body perception and BMI were not significantly associated with depression (F=2.17, p=.073, F=0.86. p=.462), the change of exercise (F=25.91. p=.055, F=20.34. p=.061), and dietary habits (F=12.96. p=.677, F=11.29. p=.505). The related factors affecting the change of exercise behavior were counter conditioning, self efficacy, eating behavior, and helping relationship, including 30.4% R-square. The related factor affecting the change of dietary habit was only eating behavior, including 20.0% R-square. Conclusion: This study can provide useful information to develop effective programs for the change of exercise and dietary habits considering university students' stages of change according to the transtheoretical model.

  • In this study, the aim was to investigate the effect of Mahwangpohang-tang on the expression of obesity-related genes and cytokines in high fat diet induced obesity mice. In order to investigate the effects of Mahwangpohang-tang(MHPH) on the obesity-related genes and cytokines, C57BL/6 mice were fed with high fat diet. C57BL/6 mice were divided into three groups and fed for 13weeks. Body weight change, diet intake change, final increase of body weight, the ratio of the adipocyte in body weight, the expression of leptin gene in primary adipocytes, the expression of UCP-2 in primary adipocytes, the production change of $TNF-\alpha$ and leptin in primary adipocytes, the expression of leptin in adipocytes tissue. The body weight of Mahwangpohang-tang(MHPH) intake mice was significantly lower than high fat diet group. The amount of the adipocyte in body weight was decreased Significantly. In primary adipocytes, leptin gene expression and the expression of UCP-2 did not change significantly. In primary adipocytes, the amount of $TNF-\alpha$ was significantly decreased at dose of $100{\mu}/ml$ density. In adipocytes tissue, the expression of leptin did not change significantly. These results suggest that MHPH may inhibit the expression of obesity-related genes and cytokines in high fat diet induced obesity mice

  • Purpose: The purpose of this study was to show the effects of voluntary change of weight bearing on the vastus medialis oblique and the vastus lateralis ratio during squat exercise. Methods: Twenty-four healthy adults were recruited for this study. The subjects performed squat exercise with median weight bearing, lateral weight bearing and non-changed weight bearing. The muscle activities of the vastus medialis oblique and the vastus lateralis were measured during the squat for all three conditions. The measured data were analyzed using one-way ANOVA to investigate the effect of muscle activation on the each condition. The statistical analyses were performed using SPSS ver. 17.0, and a p-value of less than 0.05 was considered significant for all cases. A post-hoc test was performed using Tukey's test. Results: The study showed that the vastus medialis oblique and the vastus lateralis ratio significantly changed according to the voluntary change of weight bearing during a squat. The vastus medialis oblique and the vastus lateralis ratio significantly decreased under the condition of voluntary lateral weight bearing. Conclusion: We suggest squat exercise on median weight bearing to increase the vastus medialis oblique and the vastus lateralis ratio. If your patient has.

  • The purpose of this study was to investigate the effects of turmeric intake and weight training on blood alcohol concentration, liver enzyme levels of and their effects on health promotion in adult males. There was no significant difference of taking turmeric powder combined with weight training exercise on blood alcohol levels in adult men who consumed alcohol on a regular basis. There was also no change on the change of body composition. The results were collected from elite athletes that had spent more than 10 years in their respective sports so it is difficult to observe any significant results from 8 weeks, short-term exercises of 1RM 70~80%, 3 times per week. In the next study, it is necessary to divide the subjects into more diverse groups and subject them by varying amounts of turmeric intake, exercise, etc., in order to fully study and understand the effects on blood alcohol level, change, and health promotion. Consequently, this study demonstrated there were no significant differences in the effects of continuous drinking habits of adult men's turmeric powder intake and weight training exercise on changes in GOT, GPT, γ-GTP, and blood alcohol concentrations. Moreover, health improvements themselves didn't affect changes in body composition.
