Obesity is characterized by a state of chronic low-grade inflammation and insulin resistance, which are aggravated by the interaction between hypertrophic adipocytes and macrophages. In this study, we investigated the effects of tangeretin on inflammatory changes and glucose uptake in a coculture of hypertrophic adipocytes and macrophages. Tangeretin decreased nitric oxide production and the expression of interleukin (IL)-6, $IL-1{\beta}$, tumor necrosis $factor-{\alpha}$, inducible nitric oxide synthase, and cyclooxygenase-2 in a coculture of 3T3-L1 adipocytes and RAW 264.7 cells. Tangeretin also increased glucose uptake in the coculture system, but did not affect the phosphorylation of insulin receptor substrate (IRS) and Akt. These results suggest that tangeretin improves insulin resistance by attenuating obesity-induced inflammation in adipose tissue.

The effects of liquid pig manure (LPM) on the yield and nutrient supply of green manure crops, such as hairy vetch alone and hairy vetch + rye mixture, were investigated. We used three treatments: no-fertilizer (NF); LPM, $4.0t10a^{-1}$ ($N-P_2O_5-K_2O=4.0-0.024-4.0kg10a^{-1}$); and chemical fertilizer (CF; $N-P_2O_5-K_2O=4.0-0-4.0kg10a^{-1}$). The green manure crops, namely, Vicia villosa Roth. (hairy vetch) and Secale cereale L. (rye). were sown on March 11 and harvested on June 24, 2014. Yield of green manure crops significantly increased in hairy vetch + rye mixture plot compared with the hairy vetch alone plot. In hairy vetch alone plot, yield of green manure crops was increased by application of LPM and CF, but there were no significant differences. Yield of green manure crops in hairy vetch + rye fresh mixture plot significantly increased by the LPM and CF treatments, but no difference was noted between the LPM and CF treatments. Nitrogen supply by the green manure crops was higher in hairy vetch + rye mixture plot than hairy vetch alone plot. However, there was no significant difference. Phosphorus and potassium supply significantly increased in hairy vetch + rye mixture plot compared with hairy vetch alone plot. By treating LPM and CF, the nitrogen, phosphorus and potassium supply were higher than those in no fertilizer. In conclusion, LPM could replace CF. When planting green manure crops, the hairy vetch + rye mixture was more effective than hairy vetch alone to effectively use green manure crops.

'Sangdojosaeng' is a new cultivar from bud spot of Citrus unshiu 'Sasaki unshiu' which has late maturity habit. It was found in 1996, and primary selected and named as 'JARES108' in 1998. 'JARES108' was grafted on to adult satsuma mandarin trees in Seogwipo-si and Jeju-si in 2000. Four years survey on the characteristics of trees and fruits from 2003 to 2006 was carried and confirmed the superiority. Thus it was finally selected as 'Sangdojosaeng'. 'Sangdojosaeng' is a very early wase type satsuma mandarin. It shows relatively strong tree vigor among the very early wase type varieties and its branches are spreading. Its ripening time is late October, 25 days earlier than 'Sasaki unshiu'. Compared to 'Ueno wase' which has similar characteristics with 'Sangdojosaeng' such as ripening time, tree vigor, fruit type and peel color, its soluble solid content of fruit is $0.6^{\circ}Bx$ higher and acidity was a little lower than 'Ueno wase'. Because this cultivar has good quality and its tree makes vigorous growth among very early wase type varieties in Jeju, we expect to substitute it for some very early wase type varieties such as 'Miyamoto wase', 'Ichifumi wase', 'Yamakawa wase', etc.
