  • 면역억제활성이 알려진 Cerves korean TEMMINCK var. manchur-icus Swinhoe(Nokyong) 약침(CPH)은 다모 뿔의 녹용을 열수추출한 용액이다. 본 연구에서는 녹용 약침의 효과를 adjuvant 유발 관절염 실험용쥐를 이용하여 골체, 골강도 및 골대체율의 감소를 평가하였다. 위의 골 대사 관련 검정실험을 위하여 6주령의 암컷 실험용쥐에 20일간 약물투여를 실시하였다. 실험적인 관절염유발은 실험용쥐의 뒤쪽 다리에 Adjuvant를 주사하여 유발시킨 결과, 요부의 골 무기질함량과 밀도(BMC, BMD) 그리고 압축강도는 관절염 실험용쥐에서 감소되었다. 10일 경과 후 골형성도(BFR/BS, BFR/BV)의 조직형태학적 기준척도인 혈청 osteocalcin 수가 정상대조군과 비교해 볼 때 현저하게 감소되었다. 그러나, 몸무게로 나눈 BMC치는 관절염 유발군과 정상군 사이에 큰 차이가 보이지 않았다. 그리고 골무기질 함량은 정상군에 비해 감소하지 않았다. 20일 경과후 몸무게로 나누거나 나누지 않은 BMC치 모두, 관절염 군에서 요부 몸체의 골무기질 함량과 강도가 정상군과 비교해 볼 때 현저하게 감소되었다. 잔존 소주(小柱)의 무기질 침착 표면은 현저하게 감소하였으며 파골 세포의 수는 증가하였다. 초기부터 매일 Shinsu(B23)에 CPH 약침 투여(10, 20, $50{\mu}g/kg$)는 20일 경과후 만성적인 다리 부종을 현저하게 방지하였으며, 골 무기질함량, 골강도 및 소주골 형성등의 감소와 파골세포수 증가도 완화하였다. Adjuvant주사로 장애를 받았던 연령대비 요부 길이 증가도 유지되었다. 이러한 결과는 Adjuvant에 의한 관절염 실험용쥐의 2차적인 골관절염에서 충분히 요추 몸체뼈와 강도 감소를 나타내기 위해서는 적어도 20일이 필요하다는 것을 제시하였다. 본 결과로부터 CPH가 실험용쥐의 관절염에 대한 골체, 골강도 및 골대체율을 조절하는데 유효하게 작용하고 있음을 알 수 있었다.

  • Thirty two species of coastal plants (mainly halophytes) were investigated for their free amino acids and the total and water-soluble nitrogen contents in leaves. All plants except some species (e.g. Scutellaria and Linaria) contained proline, but only Ageratum. Tetragonia and Raphanus in rather high amounts, that it can be thought to serve as a cytoplasmic osmolyte. In some plant species (Euphorbia. Glehnia. Peucedanum. Raphanus and monocotyledonous Carex and Zoysia), however, hydroxyproline. (OH-Pro) rather than proline were accumulated to a considerable extent. The concentrations of total free amino acids were low in Aster tripolium, Linaria. Lysimachia. Plantago. Rumex, Vitex and especially in the members of the Chenopodiaceae and Crassulaceae. Marked differences also occurred in the nitrogen levels. Aizoaceae, Chenopodiaceae, Convolvulaceae, Cruciferae, Euphorbiaceae and Leguminosae usually showed high values of total and soluble amino nitrogen, while the opposite was true for most of the Cyperaceae, Gramineae, Lamiaceae, Plantaginaceae, Scophuriaceae, and Verbenaceae. The free amino acids in the investigated plant species contributed very little to the nitrogen content, but in plants of Euphorbia, Messerschmidia and Orostachys. their amino acid-N made up for 25∼30% of the total nitrogen. In conclusion, only a few cases did proline known as compatible solute constitute a significant proportion of the free amino acid pool in coastal plants.

  • The purpose of this study was to examine the effects of dietary caffeine supplementation on bone mineral density and bone mineral content in ovariectomized rats. Twenty eight female Sprague-Dawley rats (body weight $210\;{\pm}\;5\;g$) were divided into two groups, ovariectomy (OVX) and Sham groups, which were each randomly divided into two subgroups that were fed control and control supplemented with caffeine diets (caffeine 0.03% diets). All rats were fed on experimental diet and deionized water ad libitum for 6 weeks. Bone mineral density (BMD) and bone mineral content (BMC) were measured using PIXImus (GE Lunar Co, Wisconsin) in spine and femur. Serum alkaline phosphatase activity (ALP) and osteocalcin and urinary DPD crosslinks value were measured as markers of bone formation and resorption. The results of this study indicate that body weight gain and food intake were higher in OVX groups than in Sham groups regardless of diets. There were no differences weight gain between the control and caffeine groups in both OVX and Sham groups. Within the OVX groups, serum Ca concentration was lower in rats fed caffeine than in rats fed the control diet. Serum ALP, osteocalcin, urinary Ca, and phosphate were not different in each group. Spine BMD, spine BMD/weight, and spine BMC/weight, femur BMD/weight and femur BMC/weight of ovariectomy groups were significantly lower than Sham groups. Within the OVX group, there were no differences in spine BMD and BMC and femur BMD and BMC. These results indicate that no significant differences in spine and femur BMD were found due to 0.03% caffeine intakes in diet in OVX rats for 6 weeks. No negative effect of caffeine in 0.03% diet on bone mineral density were found in the present study. Further investigation of the relation between caffeine and bone mineral density are warranted.

  • To investigate the bioactivities of Solidago virga-aurea var. gigantea Mig. Root (SVR), we studied the effect of a SVR methanol extract on the activity of bone metabolism. Spraque-Dawley three-week-old female rats were randomly assigned to groups as follows : non-supplemented rats and supplemented with SVR at 10, 50, 100 mg/kg bw/day. Every week determined weight gain and food intake, urine and blood examination of mineral content of calcium and phosphorus was performed each at experimental periods of 3 and 9 weeks respectively; bone mineral density and bone mineral content were also assayed. There were no significant differences in body weight or feed efficiency ratio levels. However, the biological value of calcium and phosphorus excretion in the group supplemented with SVR extract decreased significantly more than that in the group not supplemented with SVR extract. Also, spine BMD, femur BMC and pelvis BMC per weight were significantly greater on SVR extract supplemented groups than that of the control group. In conclusion, it might be expected that methanol extract of SVR does not impair the growth of rats and may improve bone metabolism in rats.

  • The genome size is one of the basic characters of an organism, and it is widely applied in various fields of biology, such as systematics, breeding biology, population biology, and evolutionary biology. This factor was recently highlighted in genome studies because choosing a representative of a plant group having the smallest genome size is important for the efficiency of a genome project. For the estimation of the genome size, flow cytometry has recently been highlighted because it is a convenient, fast, and reliable method. In this study, we report the genome sizes of 15 taxa of Lamiaceae from nine genera distributed in Korea using flow cytometry. Data pertaining to the genome size for all of our species have not been reported thus far, and the data from Agastache, Clinopodium, Elsholtzia, and Isodon are the first reported for each genus. The genome sizes of 15 genera and 39 species were reported to the Plant DNA C-values Database (http://data.kew.org/cvalues/). Scutellaria indica L. has a genome size of 0.37 pg (1C). This is the fourth smallest value among the 98 Lamiaceae taxa in the Angiosperm DNA C-value Database, indicating that this taxon can be used as a reference species in the genome studies in Lamiaceae as a native Korean species. The largest genome size observed in this study is in Phlomis umbrosa Turcz. (1C=2.60 pg), representing the possible polyploidy origin of this species in the family.

  • The purpose of this study is to compare and analyze the bone mineral content of women who went through osteoporotic menopause and that of women who are healthy. For the purpose, this researcher sampled some women and divided them into three groups. Group 1 consisted of women who were pre-menopausal and healthy, group 2, women who were post-menopausal and health and group 3, women who went through osteoporotic menopause. The researcher measured the bone density of all the subjects and compared its difference among the three groups. Then the researcher compared and analyzed the influences of bone density on the spine among women of each group or those of all the groups. Among all regions of the spine, that of most region was spongiosa which was ovally shaped. The researcher measured the bone mineral content of spongiosa which existed in a particular section of the spine between T12 and L4. Findings of the study can be summarized as follows. The older women were, the lower their bone density was. Especially, women who had osteoporosis were significantly lower in bone density than those who were healthy. In all women, except those of group 1, bone density more and more lowered as the measured region of the spine gradually moved from T12 to L4. From a statistical view, the bone density of the entire vertebral body could discriminate the groups 1, 2 and 3. But it was not possible to discriminate between the groups 2 and 3 only with the bone density of the most interested region as mentioned above.

  • This study suggests designs for fashion-cultural products that can communicate the uniqueness of Korean traditional culture. To this end, motives and printing patterns were created based on the formative beauty of traditional sewing crafts. A literature review was completed to identify characteristics of Korean traditional sewing, and the motives were developed through Adobe Illustrator CS4 and Adobe Photoshop CS4. Those motives were applied to handkerchiefs, neckties, pouches, and handbags. The sewing crafts used in this study included thimbles, bobbins, and chumoni (a Korean traditional pouch). The motives were produced in a manner that best exemplified the unique formative beauty of the sewing crafts while also presenting modern images of the crafts. The motives from thimbles reflected the lateral side of their originals, while the motives from bobbins adopted fan- or rectangular-shaped bobbins. The motives from chumoni were based on Duruchumoni and Guichumoni. A total of 12 motives were developed, and a total of 36 textile designs were suggested based on those motives. A total of 42 designs for fashion-cultural products, including handkerchiefs, neckties, pouches and handbags, were developed. Among them, motives applied to handkerchiefs were expanded to apply to scarfs, as well.

  • Irradiation is widely used for the treatment of malignant diseases, and possibly cause the osteoporosis. The densitometry and bone scintigraphy are valuable when used to monitor the patients longitudinally to access the progression of osteoporosis and risk of osteoradionecrosis. To evaluate the osteoporosis after irradiation of Cobalt-60 gamma ray on the lumbar spines of New Zealand white rabbits, bone densitometry by dual photon absorptiometry and bone scintigraphy were performed weekly. The decrease of bone density began at the first week after irradiation, and were in the nadir at 4-6th week. The osteoblastic activity measured by bone scintigraphy decreased in the first week, and was in the nadir at 4-6th week. The severity of these changes were related to the radiation dose. In conclusion, the osteoporosis before the presentation of the osteoradionecrosis can be diagnosed early with the dual photon absorptionmetry and bone scintigraphy.

  • The effects of vitamin $D_{3}$ supplementation on bone mineral density and bone mineral content in ovariectmized rats were investigated. Forty female Sprague-Dawley rats (body weight 180 g) were divided into two group, ovariectomy and Sham groups, which were each randomly divided into two subgroups that were fed casein and casein supplemented with vitamin $D_{3}$ diets. Bone mineral density (BMD) and bone mineral content (BMC) were measured using PIXlmus (GE Lunar Co, Wisconsin, USA) in spine and femur on 6 weeks after feeding. Osteocalcin and urinary DPD crosslinks value were measured as markers of bone formation and resorption. The body weight gain and food efficiency ratio (FER) were higher in OVX groups than in Sham groups regardless of diets. Serum Ca concentration and urinary Ca excretion were higher in vitamin $D_{3}$ supplemented group than in casein group in Sham and OVX. Crosslinks values were higher in OVX groups than in Sham groups. Spine BMD and femur BMD of ovariectomy group were significantly lower than Sham groups, however vitamin $D_{3}$ supplemented groups were significantly higher than control groups in Sham and OVX. In conclusion, dietary vitamin $D_{3}$ supplementation on ovariectimized rats were significantly increased bone mineral density and bone mineral content in spine and femur.

  • A recent study reported that a diet rich in isoflavones is beneficial for bone formation in growing rats. It therefore seemed desirable to find out whether the beneficial effect of isoflavones in ovariectomized rats could also be reproduced with same amount of isoflavones which used for growing rats. To study the effect of isoflavones, an equal amount of isoflavones which used for growing rats, on bone mineral density and bone mineral content in ovariectmized rats were performed. Forty female Sprague-Dawley rats (body weight $210{\pm}5g$) were divided into two groups, ovariectomy and sham groups, which were each randomly divided into two subgroups that were fed casein and casein supplemented with isoflavones diets for 9 weeks after operation. All rats were fed on experimental diet and deionized water ad libitum for 9 weeks. Bone mineral density (BMD) and bone mineral content (BMC) were measured using PIXImus (GE Lunar Co, Wisconsin) in spine and femur. Serum alkaline phosphatase activity (ALP) and osteocalcin and urinary DPD crosslinks value were measured as markers of bone formation and resorption. The results of this study indicate that body weight gain and food intake were higher in ovariectomy groups than in sham groups regardless of diets. Serum Ca concentration was lower in ovariectomy groups than in SHAM groups. Serum ALP, osteocalcin, and crosslink value were increased in ovariectomy groups. Spine BMD/weight, femur BMD/weight, and femur BMC/weight of ovariectomy groups were significantly lower than SHAM groups after 9 weeks. However, isoflavones supplemented group in ovariectomy groups, serum ALP and osteocalcin concentrations, spine BMD/weight and spine BMC, femur BMD/weight and femur BMC/weight were significantly increased after 9 weeks. In conclusion, the beneficial effect of isoflavones on bone in ovareiectomized rats was shown on 9 weeks after feeding with an equal amount of isoflavones supplementation which used for growing rats.
