Objectives : This experimental study was designed to investigate the effect of SBY-III extract on the weight, cell size of epididymal fat-pad, fat accumulation area in liver, serum lipid level and UCP1 mRNA in brown adipose tissue of high fat diet-fed obese rats continued by high fat diet and regulated by normal Diet. Methods : The body weight gain, weight of the internal organs(epididymis, liver, brown adipose tissue), insulin, triglyceride, total cholesterol, total lopod, free fatty acid, expression of UCP1 mRNA were measured in high fat diet-fed obese rats continued by high fat diet and regulated by normal diet. The experimental study are divided into exp-I and exp-II. Each study was administered normal diet, high fat diet and SBY-III according to each situation. Normal group is normal diet for 8 weeks. Exp-I are divided into control group(high fat diet for 8 weeks) and sample group(high fat diet for 8 weeks and SBY-III for last 2 weeks). Exp-II are divided into control group(high fat diet for 6 weeks and normal diet for 2 weeks) and sample group(high fat diet for 6 weeks and normal diet with SBY-III for 2 weeks). These were then compared mutually. Results : 1. Irrespective of diet control, sample group taken SBY-III showed the more effective decrease of weight gain than control group and diet control-fed sample group with SBY-III showed the more effective decrease of weight loss including weight gain than control group. 2. Irrespective of diet control, sample group taken SBY-III showed the more effective decrease cell size of epididymal fat-pad, fat accumulation area in liver than control group. 3. Non diet control-fed sample group taken SBY-III showed the more effective decrease of serum triglyceride, total lipid, free fatty acid than control group and diet control-fed sample group taken SBY-III showed the decrease of serum triglyceride, free fatty acid than control group. 4. Only diet control-fed sample group taken SBY-III showed the decrease of UCP1 volume. Conclusions : These results shows that SBY-III has effects on anti-obesity, especially keeping pace with diet control.
This thesis amis to demonstrate basically that language has the potential enough to be able to determine human's belief, attitude and behavior for Spinoza. As long as the language could be conceived with the potential to do, then it is very important in human community. And it is through dynamic and changeable, not fixed state, that meaning of this language is revealed. For Spinoza, even sign and its meaning compose one language system, but both of which are different from the other community. Because language as sign used in a specific society is articulated expression of body image, each imagination as idea is necessarily followed by its sign. This fact makes us say that language express imaginal knowledge. But language should not be considered as an means to express adequate idea of it. By the reason that order of meaning is only determined by the connection of signs, and that of meanings, each meaning of sign is not fixed. In this respect, certain meaning is changeable on account of changing new order of ideas. Through re-arranging new order of meaning, language could express more adequate and better idea than before. but what the most important fact is that it is not sufficient to express adequate idea by the means of language. Power of language determining human's belief and attitude does not depend on whether meaning of sign is true or not, but on hegemony of order of meaning. with this regard, this world could be seen as battle area of conflicting for orders of meaning. The more members accept newly created rational thought through newly arranged words, the more new views of value gain power. Solidarity of man using common language can change the world. For this purpose, first step depends on freedom of thought, freedom of deliverance of thought in which spinoza insists through A Theological - Political Treatise.

Objective : Chronic acid reflux esophagitis (CARE), one of gastroesophageal reflux disease (GERD) is increasing worldwide. Coptidis rhizoma extract (CRE) is a traditional herb that cures a variety of diseases. This study was conducted to evaluate the protective effect of CR on rats with chronic acid reflux esophagitis. Methods : The antioxidant activities were evaluated through radical scavenging assays using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazolin-6-sulfonic acid) (ABTS) radical scavenging assays. CARE was surgically induced in 5-week-old male SD rats by ligating the border between forestomach and glandular portion with a 2-0 silk tie and covering the duodenum using 18-Fr $N{\acute{e}}laton$ catheter. To evaluate the esophageal protective effect of CRE, rats were divided into 3 groups: Nor (normal rats), Veh (chronic acid reflux esophagitis induced rats), CR (chronic acid reflux esophagitis induced rats treated with CRE 200 mg/kg body weight). Results : The administration of CRE significantly prevented the mucosal injury of the esophagus tissue and histological findings improved the esophageal lesion. It has been shown that inflammation is prevented by the increase of antioxidant-related factors (Nrf-2, HO-1, SOD, catalase, and GPx-1/2) through the antioxidant pathway of esophageal tissue. The administration of CRE reduced the increase of serum peroxynitrite ($ONOO^-$) and markedly reduced the protein expression of inflammatory mediator such as $NF-{\kappa}Bp65$, $p-I{\kappa}B{\alpha}$, iNOS, and IL-6. Conclusions : Overall, these results suggest that CRE administration confirmed the protective effect of esophageal mucosa, suggesting that it is a potential treatment for chronic acid reflux esophagitis.

This study assessed the impact of the toltrazuril derivative N-(4-(4-Fluorophenoxy)-3-methylphenyl) acetamide on natural cytotoxic cell (NCC) activity of olive flounder, Paralichthys olivaceus spleen. Five groups of fifteen olive flounder, comprising non-treatment and vehicle control groups, were randomly assigned. N-(4-(4-Fluorophenoxy)-3-methylphenyl) acetamide was injected intramuscularly at doses of 120, 150 and 200 mg/kg body weight; a total of ten injections were given over the course of 30 days. The NK activity of flounder splenic cells was evaluated against YAC-1, mouse lymphoma cells or HINAE cells with a choice of co-cultivation times of 4 or 18 hrs. In case of YAC-1 co-culture we observed a significant increase in cytotoxicity at a dose of 200 mg/kg, up to 3.06 times more than that of the control group. Only the trial with the 4 hrs co-culture produced a significant difference in the HINAE cell experiment; the experimental group at the 200 mg/kg dose exhibited the maximum cytotoxicity, demonstrating 2.3 times more cytotoxicity than the control group. Furthermore, the expression level of IL-12b was markedly induced in the group with 200 mg/kg, which was 6.62 times greater than that of the control group. In terms of the altered NK cell activity, the repeated high doses of N-(4-(4-Fluorophenoxy)-3-methylphenyl) acetamide can cause changes in the normal performance of immune function.
The main goal of this study was to produce transgenic piglets by the method of injection of sperm-mediated exogenous DNA. Spermatozoa (1$\times$106 sperm of final concentration) obtained from caudal epididymis were mixed with pBC1-hEPO (20 ng/${mu}ell$) or pcDNA3 LAC Z (20 ng/${mu}ell$), and followed by electroporation (500 V, 25 ㎌). Matured oocytes having the first polar body and dense cytoplasm were selected and centrifuged at 12,000g for 6 min. After sperm injection, the oocytes were activated electrically (1.7 ㎸/cm, 30 $\mu$ sec, single pulse) in 0.3 M mannitol solution. Eggs injected sperm were cultured in NCSU 23 medium (0.4% BSA) at 39$^{\circ}C$, 5% $CO_2$ in air for 192 h. This study were comprised 3 experiments. Experiment 1 compared the developmental efficiencies between the sperm-injected oocytes (Group 1) and further activated electrically (Group 2). Experiment 2 compared the expression of pcDNA3 LAC Z in the embryos produced by Group 1 and Group 2. Finally, experiment 3 carried out transfer of embryos (1-8 cell stage) transfected with pBC1 -hEPO into surrogate recipients synchronized by injection of combination of PG600 with hCG. The rates of cleavage and development into blastocyst stage in Group 2 were significantly higher than those of Group 1 (71.3% and 28.1% vs. 43.3% and 10.3%, respectively, p<0.05). Thirty (24.2%) out of 124 embryos analyzed in Group 2 were positive by X-gal. Similarly, in Group 1, 16.3% (8/49) were positive. After transfer of 789 embryos to 7 recipient gilts, three out of them examined by ultrasound became pregnant. One recipient is in day 50 pregnancy. On day 54 of gestation, two were carried out uterotomy in order to confirm the pregnancy One had 7 and another had 2 fetuses. We conclude that injection of sperm-mediated gene transfer will be used as a valuable tool for the production of transgenic piglets.

Objectives : The present study was designed to evaluate the anti-inflammatory and anti-oxidative stress activities through regulation of Nrf2-mediated genes by Rhei rhizoma and Glycyrrhiza rhizoma combined extract (RGE) in reflux esophagitis.Methods : The antioxidant activity of RGE in vitro was measured in terms of radical scavenging capacity such as DPPH and ABTS. RGE was administered at 350 mg/kg body weight prior to induction of reflux esophagitis. Reflux esophagitis was induced that tied the pylorus and the transitional junction between the forestomach and the corpus in Sprague-Dawley rats.Results : RGE scavenged DPPH and ABTS effectively and IC50of RGE each were 4.9 μg/ml and 45.6 μg/ml. Our results show that RGE administration markedly ameliorated mucosal damage upon histological evaluation. In serum and esophagus tissue, RGE significantly suppressed the oxidative stress biomarkers. Reflux esophagitis induced rats exhibited down-regulation of antioxidant-related proteins in the esophagus; however, the levels with treatment of RGE were significantly higher than those of vehicle reflux esophagitis rats. RGE treatment caused significant reductions in activation of NF-κB transcription factor. Thus, RGE significantly exhibited potent anti-inflammatory activities by suppressing the protein expression levels of pro-inflammatory proteins such as COX-2 and iNOS and inflammatory cytokines such as TNF-αin the esophagus tissue.Conclusions : Reflux esophagitis caused considerable levels of oxidative stress in the esophageal mucosa and the administration of RGE reduced the esophageal mucosa damage through the regulation of Nrf2 and NF-κB pathways. Our findings can considered as supplementary therapy in the prevention or treatment of reflux esophagitis.
This paper pay attention to silent puppets which appear in the traditional puppet performance. Not only movement of silent puppets which are involved with expression of body of the mime, but also various methods overcome limits of the silent are studied in this paper. Through the study of performance method and historic unfolding aspects, I confirm two main points. First point is that overcome limits of the silent, through the diversity of performance aspects. Second point is that silent puppets have been existed since the early stage of history, and show typical unfolding aspects on their way. Combining two main points, We can say that silent puppets go through continuous unfolding aspects on their way and have meaning of existence. The meaning of existence are that silent puppets seek deviant desire which deviate from everyday life and transcendental desire which seek a freedom through an imagination or an idea. It is interesting that the reasons of existence are associated with the emphasis of necessity which is encouragement of audience's desire and imagination that are necessary of accomplish of mime. After all, silent puppets say that diverse attempts which overcome limits of the silent are accomplished with the performance aspects and historic unfolding aspects, and through that sought unusual communication. Through the performance methods and signification aspects, silent puppets say that diverse groping for which maximize of audience's imagination, stimulation of imagination for audience's spontaneousness, and diverse groping for audience mind performance have been performanced as well. I think that those are the voice of silent puppets for activity of mime in the korea.

Particulate matter and ultra-particle matters generally refer to very small floating dust, such as 1/6 to 1/7 and 1/20 to 1/30, respectively, compared to the thickness of human hair, and contain various types of heavy metal ions. In addition to breathing, particle matters (PM) that flows in through the gaps in the pores of the skin can induce health problems in the body's tissues and skin, so it must be removed by blocking the inflow or by washing. Through this study, we confirmed the possibility that heavy metal ions can be adsorbed and removed by using Oryza sativa (Rice) bran oil (OSBO). In addition, the cell viability is much higher than that of grain-derived components through cytotoxicity experiments, and the cytoprotective effect of an external stimulus source can be expected. It was confirmed that the expression amount of COL1A1 mRNA increased, and accordingly, it was believed that wrinkles that might be caused by moisture lost by heavy metal ions in fine dust could be alleviated. Based on the results of these experiments, we tried to present a cosmetics containing OSBO, which is a wash-off formulation, in order to finally remove heavy metals.
Objective: To examine the potential of intravoxel incoherent motion (IVIM) and blood oxygen level-dependent (BOLD) magnetic resonance imaging for detecting renal changes after iodinated contrast-induced acute kidney injury (CI-AKI) development in a diabetic rabbit model. Materials and Methods: Sixty-two rabbits were randomized into 2 groups: diabetic rabbits with the contrast agent (DCA) and healthy rabbits with the contrast agent (NCA). In each group, 6 rabbits underwent IVIM and BOLD imaging at 1 hour, 1 day, 2 days, 3 days, and 4 days after an iohexol injection while 5 rabbits were selected to undergo blood and histological examinations at these specific time points. Iohexol was administrated at a dose of 2.5 g I/kg of body weight. Further, the apparent transverse relaxation rate (R2*), average pure molecular diffusion coefficient (D), pseudo-diffusion coefficient (D*), perfusion fraction (f) were calculated. Results: The D and f values of the renal cortex (CO) and outer medulla (OM) were significantly decreased compared to baseline values in the 2 groups 1 day after the iohexol injection (p < 0.05). A marked reduction in the D* values for both the CO and OM was also observed after 1 hour in each group (p < 0.05). In the OM, a persistent elevation of the R2* was detected for 4 days in the DCA group (p < 0.05). Histopathological changes were prominent, and the pathological features of CI-AKI aggravated in the DCA group until day 4. The D, f, and R2* values significantly correlated with the histological damage scores, hypoxia-inducible transcription factor-1α expression scores, and serum creatinine levels. Conclusion: A combination of IVIM and BOLD imaging may serve as a noninvasive method for detecting and monitoring CI-AKI in the early stages in the diabetic kidney.
Purpose : To determine the role of cytokines in the apoptosis of rat's liver following irradiation. Materials and Methods : Sprague-Dawley rats were irradiated to entire body with a single dose of 8 Gy. The rats were divided Into 5 groups according to the sacrlfice day after irradiation. The liver and blood after 1, 3, 5, 7, and 14 days irradiation were sampled for evaluation of mechanism of apoptosis and role of cytokine in relation to radiation-induced tissue damage. The study was composed of microscopic evaluation of liver tissue, in situ detection method for apoptosis, immunohistochemical stain of IL-1, IL-4, IL-6 and TNF, bioassay and radioimmunoassay of IL-6 in liver tissue and blood. Results : Radiation-induced liver damage was noted from first day of radiation, and most severe parenchymal damage associated with infiltration of chronic inflammatory cells was seen in the groups of 5 days after radiation. A number of apoptosis were observed 1 day after radiation on both light microscope and in situ method. Afterwards, the number of apoptosis was gradually diminished. On immunohistochemical study, IL-1 and TNF were expressed 1, 3 days after radiation, but not expressed after that. IL-4 was not expressed in the entire groups. IL-6 was expressed with strong positivity in 1, 3 days after radiation. Bioassay and RIA of IL-6 in liver tissue and blood showed the highest value in 1 day after radiation, and the value is diminished after then. Conclusion. Apoptosis seemed to be the important mechanism of radiation-induced liver damage, and is possibly induced by the release of cytokines, such as IL-1, IL-6, TNF in view the simultaneously increased appearance of pooptosis and cytokines.
