The purpose of this study was to examine whether conjugated linoleic acid and selenium supplementation in broiler chicken diets would be effective, enhance indices of immune status and body weight, and modulate serum lipid concentration. Forty Hyline brown chickens, 1 weeks of age, were divided into 5 groups of 8 chickens. Chickens were fed the experimental diets supplemented with 1% CLA (conjugated linoleic acid; Group 1), 1% CLA + selenium (Group 2), 1% safflower-seed-oil as LA (Group 3), 1% safflower-seed-oil as LA + selenium (Group 4) or nothing (Control) for 4 weeks. After 4 weeks, serum, liver, spleen and abdominal fat were taken. Measurement of total immunoglobulin were executed using sandwich ELISA. Weight ratio of liver to body showed that the group fed with CLA were significantly higher than the group fed with CLA + selenium. Weight ratios of spleen and fat to body showed no significantly differences. In concentrations of serum total cholesterol and HDL-cholesterol, the group fed with CLA showed significantly higher values than that fed with CLA + selenium. In concentrations of serum triglyceride and LDL-cholesterol there were no significantly differences between the treatment groups. In conclusion, supplementation of CLA with selenium protected hepatomegaly and reduced level of serum total cholesterol and HDL-cholestererol in chickens.

This study was conducted to compare seed viability among 42 species after ten years of storage in the midterm storage complex ($4^{\circ}C$, 30-40% RH) at the National Agrobiodiversity Center (NAC) Korean genebank maintained by the Rural Development Administration (RDA), Republic of Korea and to suggest the relative seed longevity and suitable monitoring intervals. The germination data from initial tests and after ten years of storage were compared to measure changes in viability during storage. The decline in seed viability varied greatly among seeds from -11.5% for Triticum sp. to 80% for melon. Coriander, crowndaisy, safflower, cosmos, Chinesebellflower, waxgourd, melon, castorbean, Welch-onion, hollyhock, wild barley, and tallfescue showed significant decreases in viability of 34.2%, 73.4%, 36.5%, 30.0%, 40.2%, 71.3%, 80.0%, 65.9%, 45.5%, 51.4%, 53.0%, and 33.5%, respectively. Gardenpea, soybean, perilla, onion, wild rice, Italian-ryegrass, and pepper showed a 15-30% decline in viability, while the viability of morningglory, adzukibean, maize, and Capsicum sp. decreased by 15% to 5%. Chicory, radish, Chinese-cabbage, bottlegourd, watermelon, cucumber, pumpkin, Cucurbita sp., groundnut, kidneybean, clubwheat, sesame, wheat, Triticum sp., rice, barley, orchardgrass, buckwheat, and wild tomato showed changes in viability of <5%. The changes in storage viability also varied within families. The wild types of rice and barley showed rapid viability loss and presented different aspects from cultivars. Since seed viability of species, classified as index 1 or 2, showed germination losses >15% after ten years of storage, a viability test should be conducted with five year intervals, while species with germination loss of <15% (in index 3 or 4) can be retested at ten year intervals.

This experiment was conducted to investigate the effects of dietary safflower seed (SFS) powder and chitosan on hatching egg production and eggshell qualify in aged egg-type breeder hens. A total of four hundred 54-week-old Hy-Line Brown breeder hens were divided into five the groups and fed experimental diets either with addition of 0.25 and 0.50% SFS powder or 0.10 and 0.20% chitosan or devoid of all for 6 weeks. There were no significant differences in feed intake and laying performances among the groups. The rate of sellable egg in the groups fed diets containing SFS powder or chitosan was significantly increased compared to that of control (P<0.05), irrespective of dose-dependent manner. The addition of SFS powder or chitosan significantly improved the eggshell strength (P<0.01). Eggshell thickness was also significantly increased in the groups 134 diets containing chitosan as compared with that of control (P<0.01). Fertility and hatchability of egg set were significantly improved by dietary chitosan that those of control (P<0.05). ike contents of tibial Ca and P were significantly increased in the groups fed diets containing 0.5% SFS powder, 0.1 and 0.2% chitosan as compared with those of control. The levels of blood estrogen, calcitonin and parathyroid hormone were not affected by the dietary treatments. The overall results indicated that the proper use of some feed additives such as safflower seed powder and chitosan might provide means of improving eggshell quality and reproductive performances in aged egg-type breeder hens.

Functional healthy drinks were processed with freeze dried powders of ethanol extract from of defatted safflower (Carthamus tinctorious L.) seed cake and some useful components of the drinks were investigated. Yield of freeze dried powder was the highest as 8.42% when it extracted with 60% ethanol (60% EFDP). Each drink contained 0.02% of freeze dried powder and ranged 10.6∼13.8% of soluble solid, 2.90∼3.68 of pH, 0.10∼0.83% of titratable acidity. ‘L’ value of drink-I (DSD-I) was the highest as 94.82$\pm$2.45, ‘b’ and ‘a’ value of drink-V (DSD-V) was highest as 27.15-2.65 and 28.67$\pm$2.69, respectively. Major free sugars of drink were 6015.3∼7918.2 mg% of glucose and 1511.4∼2091.0 mg% of sucrose. The content of citric acid was the highest as 179.2∼981.3 mg%. The content of total phenol in 60% EFDP was 99.17 mg% and that of drink-II(DSD-II) and DSD-V was 307.84 mg% and 224.06 mg%, respectively. Total flavonoid was contained as 50.29 mg% in 80% ethanol extract (80% EFDP) and 125.20 mg% in DSD-V. N-[2-(5-hydroxy-1H-indol-3-yl) ethyl] ferulamide (serotonin-I) was determined as high as 18.81 ppm in 80% EFDP and ranged 2.42∼2.89 ppm in drinks. N-[2-(5-hydroxy-lH-indol-3yl)ethyl]-p-coumaramide (serotonin-II) was determined as 30.17 ppm in 80% EFDP and ranged 3.79∼4.59 ppm in drinks. Acacetin, flavonoid compound were 9.83 ppm in amyloglucosidase hydrosis + 60% ethanol extract (A + 60% EFDP) and ranged 0.98∼1.26 ppm in drinks. Electron donating ability (EDA, %) was measured and compared with 100 ppm BHA as chemical antioxidant. EDA was 93.97$\pm$2.21% in A+60% EFDP, 94.79$\pm$2.26% in DSD-I, 94.69$\pm$1.37% in DSD-II, and 93.83$\pm$1.49% in BHA. DSD-II added with hot water extract solution from Korean ginseng and safflower yellow pigment recorded the highest sensory score.

This study was to investigate the chemical compositions of germinated (GSS)- and ungerminated (UGSS)-safflower (Carthamus tinctorius) seeds. GSS had higher amount of sugar and crude fiber than UGSS, but less amounts of protein and lipid. Levels of $\alpha$-tocopherol and essential amino acids of GSS were higher than those of UGSS, although there are no difference in fatty acid composition between GSS and UGSS. Among the nine phenolic compounds detected, five phenolic compounds, except for two lignans and two flavonoids, were found in both GSS and UGSS. Four serotonin derivatives accounted for about 80 per cent of total phenolic compounds, and levels of five phenolic compounds decreased slightly with germination. These results suggest that germination may enhance the functionality of safflower seed by increasing nutritional compositions and by decreasing phenolic compounds with bitter taste and cathartic effects.

This study was conducted to estimate the days to flowering based on the effective accumulated temperature at various altitudes in the Jiri mountain region and to compare growth and yield characteristics according to the sowing date of safflower (Carthamus tinctorius) four genetic resources (local variety, IT323225, IT333473, and IT333482). The safflower four resources were sown on March 29, May 3, May 13, May 24, and June 2. The days from sowing to flowering of the safflower four resources by sowing dates were in the order of the local variety (61.0 days), IT333482 (73.2 days), IT323225 (74.0 days), and IT333473 (74.2 days). The base temperature and effective accumulated temperature for the days to flowering of the safflower four resources calculated based on the daily mean temperature were local variety 6℃, 579℃, IT323225 11℃, 766℃, IT333473 11℃, 768℃, IT333482 10℃, 750℃, respectively. As a result of applying the calculated effective accumulated temperature and daily mean temperature of the past five years (2019 to 2023) by various altitudes and the different sowing dates (every 15 days from April 1 to August 15), the days to flowering of the safflower four resources decreased from April 1 to July 15 during the sowing date and then tended to increase from August 1. In addition, the days to flowering at various altitudes were investigated in the order of plains, mid-mountain, and mountain regions. Among the yield characteristics, plant height, number of branches, number of capitula, number of seeds, and seed weight decreased as the sowing dates were delayed for the safflower four resources.

White Leghorn hens were fed a commercial formula feeds as a basal diet, which was supplemented with 3 types of plant oil safflower, evening primrose and pine seed, at the 10% level for 3 weeks. No significant changes was found between the basal diet and the oil feeding trials in the egg yolk cholesterol content, the laying rate, the egg weight, and the yolk weight, except the feed intake. In the fatty acid composition of the egg yolk lipid, however, the plant oil feedings to hens resulted in considerable increase of $C_{18:2}$ acid with a simultaneous decrease of $C_{18:2}$ acid ,and, consequently, followed by the improvement of balance with P /S and P /M /S ratio close to 1.0 and 1:1:1, which is known a desirable ratio for human health in lipid nutrition, respectively.

This study was performed to investigate therapeutic effects of Carthami Semen, Paeoniae Raidx extracts and chitosan on the growth and differentiation of human periodontal ligament cell. We found that co-treatment of methanol extracts of Carthami Semen and chitosan significantly increased the growth of human periodontal ligament cell. However, the sigle treatment groups of the extracts showed only 20-30% of the growth increase. Alkaline phosphase activity, one of differentiation markers, was increased approximately 1.5- fold by co-treatment of methanol extract of Carthami Semen and chitosan and calcified nodule formation was also increased at the similar levels as the alkaline phosphatase. But the single treatment groups showed only 20-30% increases. These results suggest that Carthami Semen and chitosan co-treatment can be used efficiently for periodontium regeneration.
