The objective of this study was to determine the anti-diabetic effect of the water extract of Neolentinus lepideus in a diabetic mouse model. Seven-week-old C57BL/KsJ-db/db mice were fed either a control diet (CD) or diet supplemented with 1% or 5% of N. lepideus water extract (NLWE1 or NLWE5) for 10 weeks. Oral administration of NLWE significantly decreased the body weight gain compared to that of CD-fed group. Mice in the NLWE group had significantly lower levels of fasting serum glucose, fatty acids, and low-density lipoprotein cholesterol compared to those in the control group. These effects were accompanied by reduced fatty liver and improved glucose tolerance in the NLWE group. Taken together, these results suggest that N. lepideus might have potential as a dietary supplement to control diabetes.

This study was carried out with the goal of improving accessibility for farmers in record management. The pre-survey for farm records found that the main reasons for lack of records were “no need” and “no time” to keep such records. Based on the results of the pre-survey of smartphone-based farm recordkeeping, the major composition articles were management books, daily work logs, analysis books and additional books compiled by setting log in, notice and suggestions. The number of smartphone- based farm record books was 4,430 nationwide. We also updated farms keeping records on seven occasions for user convenience. Regional differences in the utilization ratio of record books showed that continuous promotion and education aimed at users were key points of success for farm recordkeeping books.

In this study, the anti-oxidant, anti-tumorigenic, anti-hypertensive, anti-thrombic, anti-diabetic, and anti- inflammatory properties of 18 different species of genus Pleurotus were investigated. In addition, the amino acid, β-glucan, and polyphenol contents were also measured. The β-glucan and polyphenol contents were the highest in Pleurotus cornucopiae var. citrinopileatus (yellow Pleurotus) of all species. The yellow Pleurotus also exhibited the highest physiological activity as assessed by the DPPH IC, Cytotoxic activity, ACE activity and so on. To confirm the mechanism for the physiological activity of the yellow Pleurotus, we performed further examinations within ICR mice. The yellow Pleurotus reduced glucose, triglyceride and total cholesterol levels in the ICR mice blood for 4 weeks after feeding, and also significantly lowered both GOT and GPT levels. Taken together, our data indicates the yellow pleurotus is a promising functional food ingredient.

Background : This study provides Profitability Analysis information on Baeksoooh (Cynanchum wilfordii), One of the Crops excluded from the production cost survey. and it will contribute to increase the income of farmers. The purpose of this study was to survey and analyse the farm business performance of new economic crops cultivated in small area. Method and Results : In this study, we selected Baeksoooh, which is also called Baekhasuo, as a subject of investigation, based on the roots of C. wilfordii Hemsley. We visited 20 farmers who cultivated Baeksoooh in Jecheon, we surveyed the quantity, price of farmhouse receipts, cost of each branch, the status of agricultural machinery and facilities, and We analyzed income, operating expenses, and income per unit area. and also We set up a proper management model. It can be cultivated in all regions of Korea, but it is the main production area of Jecheon in Chungcheongbuk-do under the cool climate conditions. Most are being traded for medicinal uses. Looking at the profitability per 10a by Baeksooh's business performance, The result of this study are follows as. In the case of the top 20% farms, the gross quantity of the C. wilfordii is 332 ㎏ per 10a, the gross income was 11,418, managing cost was 2,259, income was 9,158 thousand won per 10a. In the average farms surveyed, the gross quantity of the C. wilfordii is 205 ㎏ per 10a, the gross income was 4,611, managing cost was 2,418, income was 2,193, production cost was 3,169 and net income was 1,445 thousand won per 10a. In the lower 20% farms cultivation, the gross quantity of the C. wilfordii is 46 ㎏ per 10a, the gross income was 89, managing cost was 1,848, income was – 1.759 thousand won per 10a. The professional farm management scale based on Baeksoooh's income of 20 million won is 43.4 a, it can produce 890 ㎏ with 1,176 hours per years, and the income is 9,522 thousand won Conclusion : Because the Baeksoooh being processed and circulated as health functional food have raised questions about their feasibility, Production and consumption declined sharply. but Consumption is expected to increase gradually and it is likely to grow, but prices are expected to fluctuate. Therefore, The bottom 20% farmers should benchmark the top 20% farms and cultivate the appropriate scale. and It is necessary to cultivate in consideration of supply and demand of manpower as well as proper size and cultivation.
