Xanthoceras sorbifolia Bunge, the sole species in the genus Xanthoceras, is a flowering plant in the family Sapindaceae. It is an important tree species being a source of edible oil and biodiesel with a capacity as a pioneer of degraded and desert land. Seeds of X. sorbifolia were collected from two plantations and two superior trees in Inner Mongolia; and one plantation and one superior tree in Liaoning, China. An inter simple sequence repeat (ISSR) analysis showed genetic variation among four artificial populations in China: two in Inner Mongolia (IM), one in Liaoning (LN), and one in Shandong (SD). The average percentage of polymorphic loci was 81.25 % for these four populations. Based on an analysis of molecular variance, 23 % of the total genetic variation was found among populations, and 77 % within populations. Traits of seeds varied considerably between and among areas, for example two trees produced quite different seeds in several traits although they are adjacent to each other in the same farm. As much attention has not been paid to the traits of seeds, there should be a genetic test to understand this variation. It is necessary to obtain information on seed characteristics first and then provide basic information for further research on the selection of superior trees and provenances.

Psoriasis is one of the most common inflammatory skin disorders, with a global prevalence of 2% - 3%. It is an autoimmune skin disorder characterized by excessive generation of plaques on the skin with typical long-lasting red, itchy, and scaly lesions. In this study, we aimed to elucidate the anti-psoriatic effect of the methanolic extract of Persicaria senticosa (PS), a bioactive edible plant extract used in traditional medicine, using a mouse model of imiquimod (IMQ)-induced psoriasis. The daily topical application of IMQ could induce human psoriasis-like lesion. The extract ameliorated IMQ-induced psoriasis. Furthermore, hematoxylin and eosin staining and the Psoriasis Area and Severity Index (PASI) scores indicated that topical application of PS led to an improvement in erythema, scaling, and thickness scores of the mouse dorsal skin and a considerable decrease in the epidermal thickness of the ear and dorsal skin in the IMQ-induced psoriatic mouse model. We also studied the effect of PS on the proliferation of keratinocytes using HaCaT cells. The extract inhibited cell proliferation and IL-6 and pSTAT3 expression induced by M5 cocktail (comprising interleukin [IL]-1α, IL-17A, IL-22, oncostatin M, and tumor necrosis factor-α) in HaCaT cells. Thus, PS might serve as a potential therapeutic agent for the treatment of psoriasis.

Diverse medicinal uses of different types of products obtainable from Brassica juncea have been known for centuries. Most such traditionally known uses of the plant have been centered on its seeds and oils obtainable from them. During more recent decades diverse bio-active molecules and their therapeutically interesting pharmacological properties of its green edible leaves have also been described, and they are now often considered to be effective substitutes for other so called "healthy" Brassica vegetables. However, little concentrated effort has yet been made to obtain a pharmacologically better defined phytopharmaceutical from this easily cultivable plant of commercial interest in many underdeveloped and developing countries. The main aim of this overview is to point out some possibilities for designing and developing such products from the plant for combating the rapidly spreading obesity epidemic in the developed countries and some other countries. Efforts to achieve such goals could as well be an economically more feasible, and culturally more acceptable, starting point for better understanding the potential health benefits of other vegetarian foods.

This study was conducted to investigate the utilization of cut pear branches for dyeing materials, and the dyeability of pear flowers for pressed flowers using red, orange, and green edible pigments. There was a significant difference of E values among 0.1, 0.5 and $1.0{\%}$ diluted solutions of edible pigments for the cut pear branches coming into flowers. In the higher concentrations of dyeing solutions and the longer dyeing periods, a values with the red pigments increased from 2.37 to 31.22, b values with the orange pigments increased from 7.04 to 45.85, and a - values with the green pigments increased from -3.88 to -36. Bloomed pear branches were immersed in diluted solutions with red, orange and green pigments for forty five minutes. Pear branches immersed in $0.1{\%}$ and $0.5{\%}$ diluted solutions bloomed normally, and each of the flowers were dyed in the colors of the dyeing solutions, respectively. The dyeability of the bloomed pear branches immersed in water and dyeing solutions for one hundred and twenty minutes decreased compared with those treated with red, orange and green pigments and dyed immediately. The dyeability of flowers for the cut pear branches dyed immediately after cutting was significantly increased compared with that immersed in water and dyeing solutions.

독특한 자연환경과 다양한 생물상을 지닌 제주도에서 지역민들에게 이용되어 왔던 자생버섯에 대한 전통지식을 조사하였다. 제주도 전 지역을 조사 대상으로 하였으며, 제주와 서귀포시 내에 있는 7개 읍과 4개의 면을 대상으로 총 50개의 마을을 조사하였으며 50~90대 사이의 노인들 93명을 방문하여 녹취하고 야장을 작성하였다. 그 결과 제주도에서 이용되어온 야생버섯은 모두 23종으로 나타났고, 그 중 독버섯은 2종, 약용버섯은 7종, 민속신앙에 이용되었던 버섯이 2종, 이용되지는 않았으나 관심 대상이었던 버섯이 2종, 그리고 식용버섯은 12종으로 조사되었다. 또한 야생버섯을 이용하는 전통지식으로 267건의 전통지식이 수집되었다. 그 중 식용버섯은 12종에서 197건의 전통지식이 수집되었고, 독버섯에 2종에서 43건이 수집 되었으며, 약용버섯에 대한 정보는 7종에서 16건의 전통지식이 조사되었다. 특이한 점은 동물의 분변이나 퇴비에 발생하는 Cyathus stercoreus을 이용하여 포자괴(spore mass)의 방출 상태를 보고 농사의 길흉을 점쳐왔다는 점이었다. 이는 제주지방만의 독특한 전통지식으로 추정된다.
