Effects of all-trans retinoic acid(retinoic acid) on DNA replication, H2B histone and DNA topoisopmerase I(Topo I) gene expression have been investigated in human promyelocytic leukemia cell line HL-60. DNA synthesis decreased at 24 hours after exposure of retinoic acid in the HL-60 cells. H2B histone mRNA rapidly reduced at 48 hours and Topo I and c-myc mRNA at 24 hours in retinoic acid-exposured HL-60 cells, respectively. The levels of c-myc, H2B histone and Topo I gene expression were reduced in proportion to the concentration of retinoic acid. The H2B histone mRNA in retinoic acid-exposured cells was elevated by cycloheximide treatment, while the level of Topo I mRNA was constant. These results suggest that regulations of H2B histone, c-myc and Topo I gene expression are different from one another, and repression of Topo I gene is closely correlated with c-myc gene during retinoic acid-induced differentiation of HL-60 cells.

林靖恩,李明姬 服飾文化學會 1999 服飾文化硏究 Vol.7 No.5

The objectives of this study were to investigate the relation between personality(activity, emotional stability, and dominance) and clothing design preferences, and to examine the differences of clothing design preferences according to demographic variables of men, Subjects for the study were 255 male white-collar workers ranging in ages from twenties to fifties, in Seoul and Kwangju City, Korea. The men with higher activity of personality preferred the double jacket with 4 buttons, the combination of light color jacket and dark trousers, glen check pattern jacket, herringbone pattern jacket, light beige color dress shirts. The higher the imotional stability, the higher the preferences on diverse patterns such as fine stripe, plaid, hound's-tooth check, and small check pattern. The men with higher dominance preferred dark blue color suit, glen check pattern suit, and necktie of red circle, and disliked the necktie of gray circle. The men in their 20's and 30's liked the single jacket with 3 buttons, the suit of fine stripe and the necktie of gray circle more than the 40's and 50's did. The middle income group liked herringbone pattern most among three income groups. The higher the men's age and income were, the more they liked the conservative style such as a single jacket with 2 buttons. The men who reside in Seoul liked the suit of gray circle, the jacket and trousers of same color, the patternless jacket, and the patternless suit more than the men in Kwangju. Therefore, the men in metropolitan area preferred conservative clothing image. Fine stripe pattern and patternless materials were preferred when men wore jacket and trousers of same color, while glen check pattern was preferred as the pattern of jacket when jacket and trousers of different color. Male white-collar worker liked single jacket more than double jacket, and preferred the dark blue color suit and necktie, patternless suit, fine stripe suit, and the pale blue dress shirs generally. The present findings provide that the presonality of male has influence on the clothing design preferences, and it is possible to infer men's personality by their attire.

치아이동시 골세포간 활성 조화에서 세포간 교통의 중요성이 차츰 인식되고 있으며 세포간 교통을 위한 교통반의 존재가 확인되고 있다. 동물실험 모델에서 실험적 치아이동을 통해 조성된 압박 및 견인측 치주인대에서 교통반 단백의 일종인 connexin 43의 발현을 관찰함으로써 인접 연조직 및 골 조직 내에서 세포 신호 전달 양상의 한 부분을 파악하고자 하였다. Sprague-Dawley계 백서 27마리를 대조군(3마리)과 실험군(24마리)으로 나누었으며, 실험군은 견인력(75g)을 가한 후 12시간, 1일, 4일, 7일, 14일, 28일이 경과한 후 각각 4마리씩 희생시켜, connexin 43의 발현을 면역조직화학적으로 관찰한 바 다음과 같은 결과를 얻었다. 1.대조군에서의 connexin 43 발현은 치은, 상아질, 치주인대, 치수, 골세포에서 경미하였다. 2.교정적 치아이동에 반응하는 치수, 치주인대, 골모세포, 파골세포, 골세포부위에서 connexin 43의 발현이 많았으나 치은, 상아질, 상아모세포에서의 발현은 견인력 적용기간에 관계없이 대조군과 큰 차이가 없었다. 3.치수에서 connexin 43의 발현은 교정력을 가한 4일에서부터 증가하여 7일째까지 크게 증가한 후 14일째부터 감소되었으며 28일째에는 대조군과 차이가 없었다. 4.치주인대에서 connexin 43의 발현은 주로 혈관을 중심으로 치조골 면을 따라 압박측에서 주로 나타났는데 교정력을 가한 12시간에서부터 증가하여 4일에서 가장 많은 발현을 보인 후 7일부터 감소하기 시작하였다. 5.골모세포 및 골세포에서 발현은 실험 1일째부터 출현해 4일째에 가장 많은 발현을 보였고 7일 이후에는 크게 감소하였으며 파골세포에서의 발현은 골모세포와 골세포보다 실험 4일째에 더 많이 관찰할 수 있었다. Bone remodeling in response to force requires coordinated actions of osteoblasts, osteoclasts, osteocytes, and periodontal ligament cells. Coordination among these cells may be mediated, in part, by cell-to-cell communication via gap junctions. This study was designed to evaluate the expression of gap junction, connection 43 in periodontal tissue during the experimental movement of rat's incisors, by LSAB(labelled streptavidine biotin) immunohistochemical staining fort connexin 43. Twenty seven Sprague-Dawley rats were divided into a control group(3 rats), and 6 experimental groups(24 rats) where 75g of force was applied from helical springs across the maxillary incisors. Rats of experimental groups were sacrificed at 12 hours, 1, 4, 7, 14 and 28 days after force application, respectively. And the tissues of a control group and experimental groups were studied immunohistochemically. The results were as follows : 1.In control group, the expression of connexin 43 was rare in gingiva, dentin, cementum, periodontal ligament and bone cells. 2.In experimental group, the expression of connexin 43 was increased in pulp, periodontal ligament, osteoblasts, and osteoclasts, comparing to that in control. And it was rare in gingiva, dentin, and odontoblasts regardless of the duration of force application, which was not different from that of control group. 3.The expression of connexin 43 in pulp of experimental group began to increase in 4-day after force application and got to the highest degree at 7-day. And it decreased after 14-day to be similar to that of control group at 28-day. 4.The expression of connexin 43 in periodontal ligament was noted in small capillaries adjacent to alveolar bone, showing higher intensity of immunolabelling after 4-day. And it was stronger in the pressure side than in tension side of periodontal ligament. After 7-day, decrease in connexin 43 expression was observed. 5.The expression of connexin 43 in alveolar bone began to increase 1-day, reached to the highest degree at 4-day, and decreased at 7-day. And the expression in osteoclasts was more than that in osteoblasts or osteocyte at 7-day.
