The purpose of this study was to analyze the research trends of randomized controlled trials on herbal medicine treatment for atopic dermatitis in China for the last 5 years. We searched for randomized controlled trials with the intervention of herbal medicine for the treatment of atopic dermatitis in the CNKI (China National Knowledge Infrastructure) from January 2014 to December 2018. For the screening of the paper, we used '特应性皮炎' and '异位性皮炎' which mean atopic dermatitis and search was limited to three areas within Medicine & Public Health: Traditional Chinese Medicine, Traditional Chinese Medicinal Herbs, Combination of Traditional Chinese Medicine with Western Medicine. Among the 136 searched studies, we selected a total of 34 studies and analyzed a year of publication, subject characteristics, study design and intervention, prescribed herbal medicine and herbs, pattern identification, evaluation criteria, and outcomes. Longmu decoction (龍牡湯) and Polia Sclerotium (茯笭) was the most frequently prescribed medicine and herb. The most commonly used pattern identification was Blood deficiency and Wind-dryness (血虛風燥), and among them, the most frequently prescribed herb is Rehmanniae Radix (生地黃). In most studies using the total effectiveness and SCORAD index as an outcome measure, the herbal medicine treatment group showed statistically better results than the control group. As a result of the safety assessment, the herbal medicine treatment group was reported having significantly fewer side effects compared to the control group. Hence, it was confirmed that the intervention including herbal medicine had a significant effect on atopic dermatitis. This study would be able to provide the basis of clinical research on atopic dermatitis and applied to the treatment of atopic dermatitis.

Objectives : To observe the effect of 4 kinds of Korean medicine and complex extracts on the anti-stress of chronic mild stress Rat model, so as to find out the machanism of its pharmacological effects. Methods : 64 healthy SD Rats were randomly divided into 8 groups. Model Design by chronic stress(CSM), and carried out the forced swimming test. We investigated the body weight, feed and water intake, feed conversion ratio and measured parameters to changes in swimming time, immobility time, 2 and 24 hours of feces, corticosterone hormone and blood glucose level. Results : In this experiments, body weight gain and feed intake were higher in all korean medicinal herb group. Swimming time were increased by Zizyphus jujuba and Gagamsanzointang(SZT) groups and immobility time was significantly lower by Zizyphus jujuba and Fluoxetine(FLX) groups. The result of corticosterone hormone level were significantly lower in Fluoxetine(FLX) and Gagamsanzointang(SZT) but blood glucose was not significantly difference. In 2 hours after fecal frequency result were significantly lower in Zizyphus jujuba group. but SZT group were increased. This result caused by acute stress but 24 hours of feces were restored to normal. Conclusions : 5 kind of Korean Medicinal Herbs extracts has good anti-stress effects, and also to clear the circulatory system and regulate blood glucose and improve bowel function. We suggest that use a single Korean medicine rather than the combination to relieve stress.

Lilium cernum Komarvo. is an important endangered plant belonging to the family Liliaceae. A method was developed for the rapid micropropagation of L. cernum through plant regeneration from bulb scales explant-derived calli. The bulb scales segments were cultured on Murashige and Skoog (MS) medium supplemented with 0, 0.5, 1.0, $3.0mg{\cdot}L^{-1}$ kinetin and 0, 0.1, 0.5, $1.0mg{\cdot}L^{-1}$ NAA or 2,4-D for callus induction. In media with $0.5{\sim}3.0mg{\cdot}L^{-1}$ kinetin and $0.1{\sim}1.0mg{\cdot}L^{-1}$ NAA and 2,4-D, 95~100% of explants produced callus. They were then transferred to MS medium supplemented with various concentrations of NAA (0, 0.01, 0.05 and $1.0mg{\cdot}L^{-1}$) in combination with BA (0, 1.0 and $2.0mg{\cdot}L^{-1}$) for bulbet formation. Bulbet induction (78%), weight (468 mg) and size (15.5 mm) were obtained the highest on MS medium containing $2.0mg{\cdot}L^{-1}$ BA and $1.0mg{\cdot}L^{-1}$ NAA. In vitro frequency of plant regeneration was not significantly treated in strength of MS and sucrose concentration. Chlorophyll contents in 1/2MS with $50g{\cdot}L^{-1}$ sucrose treatments were higher than those in control and another treatment. This in vitro propagation protocol will be useful for conservation and mass propagation of this endangered plant.

The aim of this study was to establish plant regeneration from leaf explants of Sedum tosaense Makino, which is globally rare and endangered species. The leaf explants of S. tosaense were cultured on the MS medium supplemented with different concentration of BA and NAA for callus induction. Callus induction was showed the highest (100%) on MS medium containing $2.0mg{\cdot}L^{-1}$ BA and $1.0mg{\cdot}L^{-1}$ NAA. The highest number of shoots were regenerated when callus were cultured on MS medium containing $2.0mg{\cdot}L^{-1}$ BA and $1.0mg{\cdot}L^{-1}$ NAA for 5 weeks. The axillary bud were cultured on the MS media supplemented with combination of BA and NAA for in vitro propagation. The highest number of adventitious shoot (7.9 per explants) formed at $1.0mg{\cdot}L^{-1}$ NAA and $2.0mg{\cdot}L^{-1}$ BA. For rooting, MS medium supplemented with or without $2.0g{\cdot}L^{-1}$ activated charcoal was tested. The optimal results were observed using MS medium supplemented with $2.0g{\cdot}L^{-1}$ activated charcoal, on which 85.7 (No. of root), 4.6 cm (length of root). 1,200 ppm $CO_2$ and 350 ppm $CO_2$ were supplied for make certain the effects of $CO_2$ on pre-acclimatization by photoautotrophic culture. 1,200 ppm $CO_2$ treatment was established higher than 350 ppm $CO_2$ treatment. Soil acclimatization of in vitro plantlets was the best in mixture soil consisted of peat moss and perlite with 100% survival rate and they showed the maximum growth.
