A destructive collar rot of safflower occurred severely research farm of at Kyongsangnam-do Agricultural Research and Extension Services in 1999. Incidence of the disease at 3 fields in Chinju was ranged from 21.6 to 34.2% Upper parts of infected stems were mostly blighted and white mycelia were found on the lesions. The same fungus was isolated consistently from the infected tissues and confirmed its pathogenecity to safflower. The causal fungus of collar rot disease was identified as Sclerotium rolfsii by the examination of colony type sclerotium formation and pathogenicity test. This fungus also causes stem rot crown rot wilt or blight on the safflower. This is the first report on the collar rot of safflower caused by Sclerotium rolfsii in Korea.

Many natural medicines have been studied for their capacity and effects of antibacterial, anti-inflammatory and regenerative potential in periodontal tissues. Safflower seed has been traditionally used as a drug for treatment of bone fracture in oriental medicine. The purpose of the present study was to compare the effects of safflower seed extract and bone substitute on bone formation and regeneration in artificial defects in mongrel dogs. The bony defects were made with round bur at mandible and tibia. Extracts of safflower seed and bovine bone were placed directly at each defect for experimental group, and the defect of control group was sutured without any other treatment. Experimental animals were sacrificed at 8 weeks. And then histopathologic reading and histomorphometric study was done. There was not significant differences between control and experimental groups in osteoclastic activity and infiltration of inflammatory cells. However, new capillary proliferation, fibrosis and new bone formation were prominent in safflower seed extract group. The mandibular defects of safflower seed extract group were healed with dense connective and bony tissues, and endochondral bone formation was observed in tibial defect of safflower seed extract group only. New bone area of safflower seed extract group was more significantly increased than that of control and that of bone substitute group. These results indicate that direct local application of safflower seed extracts on bony defects seems to reduces the early inflammatory response and to promotes the bone regeneration.

Many synthetic bone materials have been studied for their potential of regenerative effects in periodontal tissue. Safflower seeds have been traditionally used as a drug for the treatment of fracture and blood stasis in oriental medicines. The purpose of this study was to assess and compare the osseous responses in rat calvarial defects between bone substitutes such as calcium carbonate and bovine-derived hydroxyapatite and feeding of safflower seeds. The calvarial defects were made with 8 mm trephine bur in 24 Sprague-Dawley rats. Two graft materials were implanted in each experimental groups, whereas the control and safflower seed feeding groups were sutured without any other treatment. And then the rats of safflower seed feeding group were supplied with 3 g/day of safflower seeds. Each group was sacrificed at 4 weeks and 8 weeks. To study a histopathology related to bone healing and regeneration, Goldner's Masson Trichrome stain was done at each weeks. The tissue response was evaluated under light microscope. There were more osteoblastic activity, new bone formation, dense bony connective tissues in bovine-derived hydroxyapatite group compared to other groups at 8 weeks. The osseous defect area of safflower seed feeding group was filled with prominent fibrous tissues, where less inflammatory infiltration and new capillary proliferation. In the early phase of bone healing, safflower seed feeding reduces the inflammatory response and promotes the proliferation of connective tissue. These results suggest that natural bovine-derived HA and safflower seed feeding could enhance the regenerative potential in periodontal defects.

Safflower seed extract was prepared by a high-pressure extraction technology and its quality characteristics were compared to that of other conventional extraction techniques, such ultrasonic and reflux extractions. Safflower seeds were extracted with 80% aqueous ethanol by three above extraction methods, and further fractionated with Diaion HP-20 column chromatography to obtain a partially purified safflower seed extract (PPSSE). Among the three extraction techniques examined, the reflux extraction showed the higher yields of EtOH extract and PPE than the ultrasonic and high-pressure extractions. Levels of most phenolic compounds in the EtOH extract of safflower seed are higher in reflux and ultrasonic extractions than the high pressure extraction, but levels of two serotonin aglycones, N-(p-coumaroyl)serotonin (CS) and N-feruloylserotonin (FS), in PPSSE were higher in the high pressure extraction than the reflux and ultrasonic extractions. In addition, color values (L and a) of the PPSSE were higher in the high-pressure extraction than the reflux and ultrasonic extractions, although there were no significant differences in pH and UV maxima absorption spectra among three extraction techniques. These results indicate that the high-pressure extraction technology is a simple and effective extraction for preparation of a high quality of safflower seed extract containing CS and FS with anti-wrinkle activity.

The purpose of this study was to make ramyon from Korean cultured wheat by adding with hot water extract powder from safflower seed in order to add the value of it. The cooking quality, instrumental texture and sensory characteristics of ramyon were analyzed. The ramyons with 0.1%, 0.3%, 0.5%, and 0.7% of hot water extract powder(HEP) from safflower seed, control, and those with 3% and 5% of dried powder(DP) from safflower seed were compared. The yield of HEP was 7.8%. Lightness, redness, Max. weight, strength, hardness, adhesiveness, cohesiveness and springiness were measured. As the amounts of HEP and DP was increasing, ramyons smelled stronger and was getting harder and chewier, while became less transparent and had no difference in elasticity and adhesiveness. In overall acceptability, both control and ramyon with HEP had similar points. From three important factors, appearance, color and smell to make ramyon more acceptable, addition of 0.3～0.5% of hot water extract powder from safflower seed was found to be the best. However, further studies on smells are needed to make processed foodstuffs with safflower seed.

홍화씨기름의 과산화물값과 공액이중산값은 빛의 존재와 상관없이 산화시간과 산화온도가 증가함에 따라 증가했으나, 동일한 온도에서는 빛의 존재 하에서 높은 과산화물값과 공액이중산값을 보여 빛은 홍화씨기름의 산화를 촉진시켰다. 빛은 홍화씨기름 산화 및 토코페롤 분해 속도의 온도의존성을 감소시켰으며, 따라서 산화온도는 광산화에서보다는 자동산화에서 더욱 중요한 인자로 작용했다.

Safflower(Carthamus tinctorius $Linn\acute{e}$ has been traditionally used for the treatment of blood stasis, and Dipsasi Radix has been used as a drug for fracture in Chinese medicine. The purpose of present study was to examine the biologic effects of safflower extract and Disasi radix extracts on the periodontal. ligament cells and osteoblastic cells and on the wound healing of rat calvarial defect. The ethanolic extract of safflower blossom, safflower seed and Dipsasi Radix(125, 250, and 500 ${\mu}g/ml$) were prepared as test group, and PDGF-BB(lOng/ml) and unsafonifiable fraction of Zea Mays L.(125, 250, and 500 ${\mu}g/ml$) were employed as positive control. The effects of each agents on the growth and survival, ALPase activity, expression of PDGF-BB receptor, chemotactic response of PDL cell and ATCC human osteosarcoma MG63 cells in vitro were examined. The tissue regenerative effect of each extracts was evaluated by histomorphometric measuring of newly formed bone on the 8mm defect in rat calvaria after oral administration of 3 different dosages groups : 0.02, 0.1 and 0.35g/kg, per day. It was also employed the same dosages of unsaponifiable fraction of Zea Mays L. as positive controls. Safflower blossom extract, safflower seed extract, and Dipsasi Radix extract stimulate the cellular activity of MG63 cells in concentration range of $125-500{\mu}g/ml$, and safflower bolssom extract and safflower seed extract stimulate also the cellular activity of periodontal ligament cells in concentration range of $250-500{\mu}g/ml$. In activity of ALPase, $250-500{\mu}g/ml$ of safflower blossom extracts showed significant stimulating effects on MG63 cells, and the same concentration range of safflower seed extracts showed significant effect on periodontal ligament cells. In the recovery on PDGF-BB receptor expression which was depressed by $IL-1{\beta}$, $125-250{\mu}g/ml$ of safflower blossom extracts and $250-500{\mu}g/ml$ of safflower seed extracts showed significant increasing effect on MG63 cells, and $500{\mu}g/ml$ of safflower blossom extract and $250-500{\mu}g/ml$ of safflower seed extracts showed significant effect on periodontal ligament cells. In chemotactic response, among all tested group, safflower seed extracts only were chemotactic to MG63 cells and periodontal ligament cells in concentration range of $125-500{\mu}g/ml$. Also in the view of bone regeneration in rat calvarial defect model, the only group that was orally administrated 0.35g/kg, day of safflower seed extract showed significant new bone formation. These results suggested that safflower extracts might have a potential possibilities as an useful drug for adjunct to treatment for regeneration of periodontal defect.

To study effect of non-fat components present in plant seeds on lipid metabolism, defatted safflower and perilla seed powders were used in high cholesterol diets for ovariectomized (ovx) female Sprague-Dawley rats weighing 227$\pm$15g. Experimental groups were six as follows; normal group without ovariectomy and cholesterol-free diet, sham and ovx-control groups with high cholesterol and cellulose for dietary fiber, ovx-est group with the same diet as ovx-control but with eight subcutaneous injections of 50$\mu\textrm{g}$ 17$\beta$-estradiol. ovx-safflower and ovx-perilla with 29% and 16% (w/w) of each defatted powder in high cholesterol diets at the expense of cellulose. Weight gains were lower in normal and sham groups and food efficiencies were lower in normal,ovx-est and ovx-safflower groups compared with ovx-control. Uterus weights were dramatically reduced by ovariectomy but restored completely by 17$\beta$-estradiol and partially (~5%) by defatted safflower. Plasma levels of total cholesterol were not different among ovx-control, sham, vx-est and ovx-safflower groups (90.8~95.1 mg/dL) but that was lower in ovx-perilla (80.4$\pm$6.2 mg/dL). Plasma triglyceride (TG) levels were lower in sham (76.6$\pm$7.0 mg/dL) and ovx-perilla (79.2$\pm$5.8 mg/dL) groups. Liver cholesterol levels were lower in sham, ovx-est, ovx-safflower and ovx-perilla groups (26.6~29.8 mg/g) than ovx-control (36.5$\pm$3.2 mg/g). But liver TG levels were reduced only sham and ovx-est groups compared to control group. Fecal excretions of bile acid and cholesterol were highest in ovx-safflower group (30.8$\pm$5. and 32.1$\pm$5.7 mg/g) compared with other ovx groups (20.8~23.1 and 12.1~19.5 mg/g). These results suggest that both perilla and safflower seeds contain groups (20.8~23.1 and 12.1~19.5mg/g). These results suggest that both perilla and safflower seeds contain non-fat and non-fiber components having lipid lowering effects.
