Objectives : The aim of this study was to evaluate the single oral dose toxicity and safety of Bojungikgi-tang (Buzhongyiqi-tang) and fermented Bojungikgi-tang (Buzhongyiqi-tang) extracts in male and female ICR mice. Methods : In the single oral dose toxicity study, non-fermented and fermented Bojungikgi-tang (Buzhongyiqi-tang) were administered to male and female ICR mice as an oral dose of 1250, 2500 and 5000 mg/kg. Changes of body weights, general behaviors, adverse effects and mortality were determined throughout the experimental period. Hematological parameters, serum chemistry, organ weights and necropsy findings were evaluated at the end of the experiment. Results : There was no mortality or sign of toxicity in the single oral dose toxicity study. There were also no significant differences in body weights, organ weights, and hematological parameters, serum chemistry values between treatment and control groups. Conclusions : The results obtained in this study suggest that the 50% lethal dose of fermented Bojungikgi-tang (Buzhongyiqi -tang) in both female and male mice can be considered as well over 5,000 mg/kg, so these medicines can be safe in clinics.

1. The effects of chloroform to the tissue lactic dehydrogenase (LDH) activities and its isozymes and to the tissue glutamic dehydrogenase (GDH) activities and its isoaymes are studied using the experimental albino male adult rats in this paper. The tissues studies are liver, kidney, heart, and brain. Besides the control group, two experimental groups are studied providing succeedingly 4 days interpariental administrations of chloroform, 0.0025ml and 0.025ml per day respectively. The changes of body weights, weights of organs, activities of GDH and LDH and their isozymes of each tissues, are analysed. 2. The body weights of rats are decreased due to the chloroform administration. 3. There are no significant differences of weights of organs due to the chloroform administration. 4. The significant decreases of tissue GDH activities and the significant changes in percent distribution of the GDH isozymes are found due to the chloroform administration. This weight be interpretated that chloroform effects to the protein and amino acid metabolism of rats. 5. Due to the chloroform administration, the significant changes in tissue LDH activities and in percent distribution of tissue LDH isozymes indicating the decreases of $LDH_1$ which is the aerobic heart type and the increase of $LDH_5$ which is the anaerobic muscle type, are observed. This could be estimated that chloroform effects to the carbohydrate metabolism, particularly to the anaerobic glycolysis of rats.

중년기 여성들에서 체중증가로 인한 여러 가지 건강문제가 심각해지는데 폐경으로 인한 sex steroid hormone의 변화에 기인되는 것으로 생각된다. Sex steroid hormone의 부족은 체중, 특히 체지방의 축적을 가져오고 한편 뼈의 손실을 가져온다고 알려져 있다. 본 연구에서는 폐경기 후의 여성들과 유사한 조건을 만들기 위해 성숙한 암쥐를 이용하여 난소절제를 한후 장기적인 체조성의 변화를 조사하였다. 난소절제한 쥐들은 체중과 체지방의 무게가 유의적으로 증가한데 반하여 근육과 뼈의 무게는 대조군과 비교할 때 커다란 변화가 없었다. 이 연구결과는 폐경기 여성들에게 일어나는 체조성 변화에 미치는 sex steroid hormone의 영향을 조사하기 위한 실용적인 animal model로 난소절제한 쥐의 사용가능성을 암시해 주고 있다.

Objectives : The object of this study was to observe the favorable anti arthritic effects of Euiiin-tang($y{\grave{i}}y{\breve{i}}r{\acute{e}}n-t{\bar{a}}ng$) aqueous extract(EIITe), has been traditionally used in Korean medicine for treating rheumatoid arthritis on collagen induced arthritic(CIA) DBA/1 mice. Methods : In the present study, effects of EIITe on the releases of human tumor necrosis factor(TNF)-${\alpha}$, interleukin(IL)-$1{\beta}$, matrix metalloproteinase(MMP)-13 and production of Nitric oxide(NO) were observed by in vitro. In addition, to observe the effects on the CIA mice, three different dosages of EIITe, 300, 150 and 150 mg/kg were orally administered once a day for 18 days from 24hrs after antigen challenges(type II collagen) on 21 days after immunization using Type II collagen Freund's complete adjuvant. Six groups, each of 8 DBA/1 mice per group were used in the present study as follows. Changes on the body weights, macroscopic arthritis scores, splenic weights, splenic TNF-${\alpha}$ and IL-6 contents, articular cartilage(femur and tibia) collagen and glycosaminoglycans-chondroitin sulphate, sulphate and hyaluronic acid contents, histopathological observations(microscopic arthritis scores, thicknesses of femur and tibia cartilage thicknesses were monitored, compared to that of dexamethasone, a potent anti inflammatory agents, 1 mg/kg treated mice. Results : As results of collagen challenges, marked decreases of body weights and gains, articular cartilage collagen and glycosaminoglycan - chondroitin sulphate, sulphate and hyaluronic acid contents were observed with increases of macroscopic arthritis scores, splenic weights, splenic TNF-${\alpha}$ and IL-6 contents, articular cartilage(in the both femur and tibia) loss and damages. However, these CIA signs were significantly and dosages dependently inhibited by treatment of EIITe 300 and 150 mg/kg as compared with CIA control, respectively. In addition, the releases of TNF-${\alpha}$, IL-$1{\beta}$, NO and MMP-13 were markedly and dose dependently inhibited by treatment of EIITe, invitro. Although CIA were more favorably inhibited by treatment of dexamethasone 1 mg/kg as compared with EIITe 300 mg/kg, marked decreases of body weights were detected in dexamethasone 1 mg/kg treated mice. Conclusions : The results obtained in this study suggest that over 150 mg/kg of EIITe showed favorable anti arthritic effects on the CIA mediated by immunomodulatory and/or anti oxidative effects. However, detail mechanism studies should be conduced in future with the screening of the biological active compounds in this herb. lthough CIA were more favorably inhibited by treatment of dexamethasone 1 mg/kg as compared with EIITe 300 mg/kg, marked decreases of body weights were detected in dexamethasone 1 mg/kg treated mice, in the present study.

Objectives The object of this study was to observe the effects of Hyeongbangjihwhang-tang (HB; Soyangin prescription) on the 5/6 NTX induced CRF rats. Methods Each of Hyeongbangjihwhang-tang aqueous extracts 200mg/kg were orally administered once a day for 35 days from 4 weeks after 5/6 NTX surgery. Four groups, each of 8 rats per group were used in this study, were sham group, CRF group, ${\alpha}$-Tocoperol group and HB group. Changes on the left remnant kidney weights, serum BUN, creatinine levels, caspase-3, PARP immunoreactivities were observed to nephroprotective effects, and relative immunomodulatory effects were monitored based on the changes of lymphatic organ weights and splenic cytokine contents. In addition, the changes on the kidney MDA, GSH contents and SOD, CAT activities were also calculated for antioxidant effects, and the effects on the CRF related cachexia were demonstrated based on the changes of body and epididymal fat pad weights, serum TG, TC, LDL and HDL levels. Results and Conclusions 1) HB was significantly decreased the left remnant kidney weights, serum BUN, creatinine levels and caspase-3, PARP immunoreactivities. 2) HB was significantly increased lymphatic organ weights and splenic cytokine contents. 3) HB was significantly increased body and epididymal fat pad weights, and was significantly decreased serum TG, TC, LDL and HDL levels. 4) HB was significantly decreased MDA contents, and was significantly increased GSH contents and SOD, CAT activities. The results obtained in this study suggest that HB significantly retarded immunosuppressions and cachexia related to the 5/6 NTX induced CRF through modulations of oxidative defense systems. Especially HB showed the highest favorable effects more than those of ${\alpha}$-tocoperol.

The purpose of this study was to assess the relationship between the mother's interest in weight control and its association with the preschooler's obesity and weight related concerns. This was a cross-sectional study based on 470 parents' self-reports. To score interests in weight control, mothers rated each of 6 items on a five-point Likert scale ranging from disagree (1) to agree (5). The perceptions of mothers' weights and their children's weights, mothers' Body Mass Index (BMI), preschoolers' Weight-Length Index (WLI) (%), and weight-related concerns were determined. The mothers' BMI was significantly correlated with interest scores of weight control in mothers (r=0.632, p<0.001) while their children's obesity was weakly correlated with the mothers' interest scores (r=0.133, p=0.025). Mothers with a high interest of weight control reported higher percentages of family history of obesity than mothers with lower interests (63.2% vs. 36.8%, p<0.001). Two-thirds of the mothers (65.4%) were accurate in their perceptions about their weights. Similarly, 63.7% of mothers knew exactly their children's weight-statuses. Compared with mothers with low interest in weight controls, mothers with high interest in weight control had lower correct-perceptions about their weights (p<0.05) but higher correct-perceptions about their children's weights. More than two-thirds of mothers (85%) reported not worrying about their children's obesity in the future. Only 14.3% of the mothers were satisfied with their current weight statuses. Three-fourths of mothers preferred exercise as an effective weight-control method for their children, 20% preferred diet therapy and 5.5% preferred behavior modification. More girls were overweight / obese, than boys (overweight: 16.1% (girl) vs. 12.8% (boy), obese: 5.4% (girl) vs. 4.5% (boy)). About 40% of overweight girls' mothers had low interests in their weight controls with low correct-perceptions in their children's weights, which suggests possible elevated risk of obesity, especially in girls, in the future.

This study investigated heritability for bovine growth estimated with genomewide single nucleotide polymorphism (SNP) information obtained from a DNA microarray chip. Three hundred sixty seven Korean cattle were genotyped with the Illumina BovineSNP50 BeadChip, and 39,112 SNPs of 364 animals filtered by quality assurance were analyzed to estimate heritability of body weights at 6, 9, 12, 15, 18, 21, and 24 months of age. Restricted maximum likelihood estimate of heritability was obtained using covariance structure of genomic relationships among animals in a mixed model framework. Heritability estimates ranged from 0.58 to 0.76 for body weights at different ages. The heritability estimates using genomic information in this study were larger than those which had been estimated previously using pedigree information. The results revealed a trend that the heritability for body weight increased at a younger age (6 months). This suggests an early genetic evaluation for bovine growth using genomic information to increase genetic merits of animals.

Increasing demands of high corrosion resistant sheet steels for the automotive body panels have been leading to a tendency toward heavier coatings of electroplated sheet steels. The specimens were prepared from lab-scale electroplating simulator with various coating weights of zinc, zinc-iron and zinc-nickel coated sheet steels and evaluated in the light of the application for the automotive body panels. Corrosion resistances by sacrificial action were improved with increasing coating weights for all electroplated sheet under survey, but blistering resistances of pure zinc coated sheet steels were not as much. On the other hand, the adhesions of heavy alloy coatings showed poor powdering performances by the external compressive or tensile forces.

The objectives of this study were to investigate the progress of obesity in women from childhood to adulthood and to analyze the characteristics of obese figures through comparing their body proportions to normal-weight people, to provide a basic reference for development of new size categories and improved pattern grading. Body measurement was made on 6,704 women age between 7-39 in Sizekorea 2004 database. The age range was divided into three groups: children(7-12), teenagers(13-18) and adults(19-39). The result of research into the characteristics of body proportions of obese figures and the classification of different figure groups of obese people are as follows: The ratio between width and circumference for each part of the body was investigated according to body weight which was grouped into three different weights of low, normal and obese body weights. And the result demonstrated that in all the ranges of age, the obese groups had the lowest ratio between width and circumference, having a thick body shape. And according to the result of comparing the ratio of the circumference of each body part divided by the waist circumference, the obese group also showed a low ratio, indicating that they have bigger waist circumference than any other body parts. By analyzing the ratio of circumference of body parts divided by waist circumference, three factors were identified as contributing to obesity. Using the factor loadings of the upper, distal and lower body obesity, a cluster analysis was carried out and three different categories of obesity were defined; abdominal obesity, distal obesity and proximal obesity.
