  • Background and Objective : Atractylodes japonica (AJ) is a commonly-used herbal medicine in Asian countries such as Korea, China and Japan. The present study was designated to evaluate the direct effects of AJ on helper T cell activities and on Th1/Th2 lineage development in vitro. Materials and Methods : Spleen cells from 8-week BALB/c mice were cultured in CR extracts containing medium without activation for 24 hours and with activation for 48 hours. CD4+ T cells were isolated and analyzed for mRNA expression levels of INF-$\gamma$, IL-4, T-bet and GATA-3 by RT-PCR and secretion cytokines levels of INF-$\gamma$, IL-2, IL-4, IL-5 and IL-10 by ELISA. Results : The results demonstrated that AJ had no mitogenic effects on unstimulated CD4+ T cells, but augmented CD4+T-cell proliferation upon activation with anti-CD3/anti-CD28 antibodies in a dose-dependent manner. AJ treatment significantly increased CD4+ T cell population and IFN-$\gamma$ expression was significantly enhanced, while IL-4 expression significantly decreased. In addition, in vitro Th1/Th2 polarization experiments revealed that AJ enhanced IFN-$\gamma$ secretion in Th1 cells, but reduced the IL-4 in Th2 cells in dose-dependent manner. Conclusion : These results suggest that AJ treatment could be a desirable alternative therapy for the prevention or correction of Th2 dominant pathological disorders, such as allergy and asthma.

  • The Purpose of this article is to study the excavated women's costume of the Joseon Dynasty, and to help identify the period of those costumes with the time of the burial unknown. The excavated women's costume is concentrated in 16th to 17th century, and the reason is due to the method of the burial. The characteristics of costumes from each period is as follows. The special features about 15th century costumes are the women's Dan-ryeong(round-collared jacket), Dae-gum style shirt(shirt with the squared collar facing each other), and skirt with horizontal dart. The 16th century costumes are the women's Dan-ryeong, wide Jegori with various length, skirt with horizontal dart, skirt with its hem folded, and pants with shoulder strap. In the 17th century, the formal dress changes to Won-sam from Dan-ryeong. The collar changes from the squared shape to the cut Dang-ko collar, and the skirt with its hem folded is not seen after the early 17th century. The long jacket changes to Dang-ui and gets settled, and the clothes becomes smaller and tighter. In the 18th century, the women's formal dress gets settled to Won-sam and Dang-ui, and the pants with shoulder strap is no longer seen. Jegori becomes shorter and smaller compared to those from the 17th century, and again gets wider and bigger in the late 18th century, and it leads to the change of making a big sized shroud.

  • In order to study the effects of iron and zinc on the lead poisoning of rats, lead with iron and zinc, or lead alone were administered orally to a total of 98 adult rats of Sprague-Dawley Species. The concentrations of lead, zinc, and iron were measured by atomic absorption spectrophotometer at every 20 days intervals of 20th, 40th, 60th, 80th and 120th day as a final measurement. Those datas were analysed and compared with those of control groups. The results were summarized as follows; 1. The concentration of lead in blood, bone. and liver tissues kept increasing in case of lead exposure group whereas it started decreasing at 60-80th day when concentration of zinc started increasing in case of combined exposure group. However, in kidney tissue, the concentration of lead in combined exposure group kept increasing up to the end of observation showing special high concentration at the final measurement at 120th day. 2. Concentration of zinc in blood and liver tissues had increased from 60-80th day in case of combined exposure group. 3. Concentration of iron in blood showed decreasing from $44.15{\pm}9.67\;to\;32.44{\pm}2.69{\mu}g/ml$ in case of lead exposure group, whereas it showed constant level of $47.50{\sim}45.65{\mu}g/ml$. However, in liver tissue it kept constant as control did from 40th to 60th days, but from 100th day on it started increasing to show much higher concentration than control.

  • This study focused on front-blouse-type skirts from the 15th and 16th centuries and aimed to investigate their formative characteristics and wearing patterns. Previous studies, literature, records, paintings, and excavated clothing items were used as research materials. The researcher categorized front-blouse-type skirts into three types based on the construction method. The first has the front-center portion of the skirt folded up, the second has the center portion cut short, and the third has horizontal dart pleats on either side. An examination of 48 items from 18 excavation sites of front-blouse-type skirts showed that only the front-center portion folded up type appeared in the 15th century, and it was only in the 16th century that the other forms of skirts were worn. Finally, based on the analysis, the pattern of wearing front-blouse-type skirts and their changing factors was deduced. Front-blouse-type skirts were identified as ceremonial skirts that were popular in the 15th and 16th centuries among the types of long skirts available. The popularity and usage of this type of skirt began to spread gradually in the 15th century. In the 16th century, various types of front-blouse-type skirts were brought into vogue by the royal family and the external register. It can be inferred that the popularity of front-blouse-type skirts gradually declined in the 17th century as other types of long skirts, folding skirts, and Sran type skirts emerged.

  • Purpose: This study investigated the cumulative effects of depressive symptoms on cognitive function over time in community-dwelling older adults. Methods: Data were investigated from 2,533 community-dwelling older adults who participated in the Korean Longitudinal Study of Aging (KLoSA) from the 5th (2014) to the 8th wave (2020). The association between cumulative depressive symptoms and cognitive function was identified through multiple regression analysis. Results: When the multiple regression analysis was conducted from each wave, the current depressive symptoms scores and cognitive function scores were negatively associated, regardless of the waves (B5th = - 0.26, B6th = - 0.26, B7th = - 0.26, and B8th = - 0.27; all p < .001). Further, when all the previous depressive symptoms scores were added as explanatory variables in the 8th wave, the current one (B8th = - 0.09, p < .001) and the previous ones (B5th = - 0.11, B6th = - 0.09, and B7th = - 0.13; all p < .001) were also negatively associated with the cognitive function score. The delta R2, which indicates the difference between the model's R2 with and without the depressive symptoms scores, was greater in the model with all the previous and current depressive symptoms scores (6.4%) than in the model with only the current depressive symptoms score (3.6%). Conclusion: Depressive symptoms in older adults have a long-term impact. This results in an accumulated adverse effect on the cognitive function. Therefore, to prevent cognitive decline in older adults, we suggest detecting their depressive symptoms early and providing continuous intervention to reduce exposure to long-term depressive symptoms.
