Much attention has been given to the role of safflower (Carthamus tinctorius L.) seed in preventing and treating osteroporosis recently. Although numerous studies were done on effects of safflower oil, no attention was given to the role of dietary fiber of safflower seeds. This study was aimed at investigating physiological significance of defatted safflower seed as a source of dietary fiber. Sprague Dawley female rats were assigned one of 5 groups: ovariectomized control (Ovx-control) group and ovariectomized rats 15% (Ovx-ss15) and 30% defatted safflower seed (Ovx-SS30), sham-operated (Sham) group and a normal group. Cholesterol was supplemented to all diets at 0.5% except the normal diet. Ovariectomized rats were pair-fed isocalorically to the Sham group. Ovariectomy caused heavier body weight, but feeding 30% safflower seed brought back to the level of Sham group. Activities of disaccharidases of jejunal mucosa were significantly lowered in Ovx-control group compared to those of Sham, and supplementation of safflower seed tended to increase the activities. Fecal weight of Ovx-SS15 and Ovx-SS30 were almost twice as those of Ovx-control Sham. Propionic acid and butyric acid concentrations per g of feces of Ovx-SS15 and daily excretion of these fatty acids were significantly increased as compared to those of Sham and Ovx-control. In concentration defatted safflower seed supplementation significantly increased fecal bulk and short chain fatty acid production in large intestine of rats.

본 실험은 경실 종자인 잇꽃의 종자구조와 발아특성을 밝히고자 수행하였다. 잇꽃 종자의 외형적 특징은 단단한 종피 표면에 제(hilum)와 주공(micropyle)이 있으며, 제는 종자의 발달과정에서 태좌와 연결되어 있었고, 주공은 암술대와 연결되어 있었던 부분이다. 종자 침종 후 2-3시간 후에 제의 표면이 열렸으며, 발아 시 유아(embryo)가 제를 뚫고 돌출되었다. 잇꽃 종자의 흡습 전에 제와 주공에 파라핀을 처리하여 밀봉한 결과, 제 부위를 밀봉한 처리에서 종자의 발아가 이루어지지 않아 잇꽃 종자의 수분과 산소 교환이 제를 통하여 이루어진다는 것을 확인하였다. 잇꽃 종자의 제가 물에 잠기도록 수분을 공급한 발아실험(top of paper method)에서는 $15^{\circ}C$에서 31.3%, $20^{\circ}C$에서 15.7%, 그리고 $25^{\circ}C$에서 6.0%가 발아하였으며, between-paper method에 의한 실험에서는 $15^{\circ}C$에서 45.5%, $20^{\circ}C$에서 30.0%, $25^{\circ}C$ 14.0%로 발아율이 나타났고, 토양에 파종한 종자는 온도에 관계 없이 80% 내외의 발아율을 보여, 잇꽃 종자의 발아에 수분공급 조건과 온도가 밀접하게 연관되어 있었다. 제(hilum)의 내부 구조를 SEM(scanning electron microscope)을 이용하여 관찰한 결과 도관요소를 구성하는 세포로 이루어져 있었다. 이러한 결과로 볼 때, 잇꽃 종자의 제(hilum)는 발아과정에서 수분흡수와 가스교환 통로가 되는 것으로 판단된다.

We conducted this study to examine the effects of safflower seed granular tea containing physiologically active polyphenols on antioxidative activities and bone metabolism. Forty postmenopausal women ages 49 to 64-years were recruited from Daegu and Gyeongbuk and were randomly assigned to either a safflower tea supplement (Saf-tea) group (n=27) or a placebo group (n=13). The Saf-tea group received 20 g of safflower seed granule tea per day containing a 13% ethanol extract of defatted safflower seeds, whereas the placebo group received a similar type of tea that lacked the ethanol extract. No significant changes in nutrient intake for either the placebo or Saf-tea groups were observed before or after the study period, except vitamin A intake increased after 6 months in the Saf-tea group. Dietary phytoestrogen intakes were similar in the Saf-tea group (60.3 mg) and placebo group (52.5 mg). Significant increases in plasma genistein and enterolactone were observed in the Saf-tea group. After 6 months of supplementation, serum levels of antioxidant vitamins such as a-tocopherol and ascorbic acid increased significantly, and TBARS levels decreased in the Saf-tea group compared to the placebo group. Serum osteocalcin levels were reduced (P<0.05) in the Saf-tea group after 6 months, whereas serum osteocalcin did not change in the placebo group. Urinary deoxypyridinoline/creatinine excretion was not different between the two groups at baseline, and did not change in either group after 6 months. Bone mineral density decreased significantly in the placebo group (P<0.01) but not in the supplemented group. It was concluded that polyphenols (72 mg/day), including serotonin derivatives, in the Saf-tea had both antioxidant and potential bone protecting effects in postmenopausal women without liver toxicity.

본 연구는 흰쥐의 난소제거로 유발한 골다공증에 대한 흥화씨(Carhamus inctorius L)의 투여 효과를 알아보기 위하여 혈청내 호르몬과 골소주의 변화를 관찰하였다 실험동물은 4개월 령의 흰쥐를 난소절제를 실시하여 골다공증을 유발 시킨 후 실험에 이용하였으며 30일간 격일 간격으로 0.03g/kg의 용량을 투여 하였다. 혈청 내에서 Insulin-like Growth Factors, Insulin-like Growth Factor binding protein-3 (IGFBP-3), Estrogen, Bone-specific alkaline phosphotase, Calcium, and Phospotase를 매 10일 간격으로 측정하였으며 비골의 골간을 채취하여 조직 형태학적인 검사를 실시하였고 체중에 대한 대퇴골 무게를 측정하였다. 홍화씨 투여 10일과 20일에서는 혈청내 IGF-I, IGF-II그리고 IGFBP-3의 변화는 대조군에 비하여 유의성 있는 변화를 관찰할 수 없었으나 홍화씨 투여 30일에 있어서는 IGF-I, IGF-II그리고 IGFBP-3의 변화가 대조군에 비하여 현저히 높은 유의서 있는 변화를 관찰할 수 있었다(p<0.05). Bone alkaline phosphatase(BALP)에 있어서도 홍화씨 투여 30일 에 가장 많은 변화가 있었으나 estrogen과 체중에 대한 대퇴골의 무게에 있어서는 유의성 있는 변화를 관찰하지 못했다. 오히려 이시기에 난소를 절제하지 않는 대조군의 estrogen치가 높게 나타났다. 난소절제로 골다공증을 유발시킨 흰쥐에 있어서 흥화씨의 투여는 혈청내 IGFs, IGFBP-3 and BALP을 높임으로서 골다공증 치료에 효과가 있는 것으로 사료됩니다.

Recently, use of natural medicine is getting more attention, and some of them are believed to be effective in　the treatment of periodontitis. Among them, the seeds of safflower(Carthamus tinctrorius L.) have been proven to be effective through its use in bone diseases such as fracture and osteoporosis. During the last few years, studies using the seeds of safflower gown in Korea have been active, and it has been reported that safflower seed extract increase the proliferation and the alkaline phosphatase(ALP) activity of human periodontal ligament fibroblast(hPDLF), osteoblast, and that they promote the mineralization process. In animal studies, when safflower seed extract were administered orally new bone formation was promoted. Recently, in an effort to find out the most effective osteogenic components, among many components of the safflower seed, various safflower seed fraction extracts were obtained by multistep extraction of the safflower components using various solvents. Among these, saf-M-W fraction extracted by methanol and water was most effective in increasing osteogenic potential of osteoblasts. In this study, the effect of safflower seed fraction extract, saf-M-W, on the growth and differentiation of hPDLF and MC3T3-E1 cell was investigated. The toxicity of saf-M-W on both cells was measured using M'IT(3-(4,5dimethylthiazol-2-y1)-2,5-diphenyl tetrazolium bromide) test, and ALP activity was measured using the colorimetric assay of hPDLF. In addition, in MC3T3-El cells, the expression of ALP, bone sialoprotein(BSP) mRNA was observed using Northern blot, and the mineralized nodule formation Was observed using von Kossa stain and phase-contrast microscope. 1. In concentrations below $10{\mu}g/ml$, saf-M-W didn't show any toxicity on hPDLF and MC3T3-El cell. 2. The change in saf-M-W concentration had no effect on the ALP activity of hPDLF. 3. In MC3T-E1 cells, mRNA expressions of ALP and BSP were greater in the experimental group treated with $10{\mu}g/ml$ concentration of saf-M-W compared with the control group. 4. In MC3T3-El cells, abundance of mineralized nodules were formed in the experimental group treated with $10{\mu}g/ml$ Concentration of saf-M-W, while no mineralized nodule was formed in the control group. These results suggest that safflower seed fraction extract, saf-M-W. didn't show any toxicity on hPDLF and MC3T3-E1 cell at concentrations below $10{\mu}g/ml$ and effectively enhanced the differentiation and osteogenic potential of MC3T3-El cell.

The purpose of this study was to analyze the sensory and mechanical characteristics, moisture content and color values of Hongwhasulgi by varying the quantity of Safflower seed powder and the types of sugar used. As a result of the quantitative analysis, it was found that as more Safflower seed powder was added to the non-glutinous rice powder, the tastiness, sweetness and coarseness of the resultant rice cake tasted almost the same as that of the raw seeds. When the quantity of the seed powder was the same, Hongwhasulgi with sugar added was moister than that with oligosaccharide, and as more seed powder was added, the rice cake became less chewy. The preference of flavor did not differ significantly among the samples. As a result of analyzing the texture, Hongwhasulgi with more Safflower seed power added and oligosaccharide used exhibited greater hardness, adhesiveness, gumminess and chewiness but lower cohesiveness, whereas springiness did not differ significantly among the samples. The moisture content of Hongwhasulgi ranged from $32.35{\sim}39.87%$. Hongwhasulgi with the sugar added was significantly moister than that with oligosaccharide added(p<0.05). Based on the above results, it is considered that the most desirable mix ratio for Hongwhasulgi is non-glutinous rice powder 190 g(95%), Safflower seed power 10 g(5%), sugar 20 g, salt 2 g, and water 35 mL.
