This study was carried out to investigate the effects of diet of Korean safflower(Carthamus tinctorious L.) seed powder on bone tissue during the recovery of rib-fracture in rats. Male Sprague-Dawley rats of 10 weeks old, weighing 370$\pm$5g, were divided into two groups including the control group(C group, AIN-76 semipurified diet) and safflower seed group(S group, AIN-76 semipurified diet+10% safflower seed powder) and were fed experimental diets for 12 days after adaptation period. After this period, the 9th right rib was fractured surgically and sham-operation was also performed. Rats were fed with experimental diets for up to 30 more days after rib-fracture. The degree of bone repair was evaluated during the recovery period at the 8th, 11th, 16th, 21st, 30th days after the surgical operation by microscopic observation of the fractured rib tissue. In callus formation, the portion of hyaline cartilage was noticably higher in S group than C group. The intracatilagenous ossification was observed at the 8th day in S group, but at 11th day in C group. The intramembranous ossification in callus was widely found over the 8th day to the 11th day in S group, but it was shown over the 11th day to the 16th day in C group. Bone resorption was also occured more rapidly in S group as indicated by large numbers of osteoclasts observed. At the 30th day, most of trabecular bones were disappeared in S group, whereas still shwon in C group over wide ranges of fractured ribs. These results imply that the supplementation of Korean safflower seed powder influences in the recovery of bone fracture by accelerating the process of bone repair.

Magnoliae cortex has been used as a drug for treatment of fractures in Chinese medicine and safflower(Carthamus tinctorius $Linn{\acute{e}}$) has been traditionally used for treatment of blood stasis. The purpose of present study was to examine the biologic effects of magnoliae cortex extract and safflower extract mixture(MSM) on human periodontal ligament cells and fetal rat calvarial osteoblasts and on healing of rat calvarial defects. The ethanolic extracts of magnoliae cortex(MCE), safflower seed(SSE), Zea May L(ZML) were prepared as positive control group. MSM mixed to the ratios of 1 : 1, 1 : 2, 1 : 5 and 1 : 10 were used as test group. The effects of each agents on the growth and survival, ALPase activity, cell proliferation and tissue regenerative effect of each extracts was evaluated by histomorphometric measuring of newly formed bone on the 8 mm defect in rat calvaria after oral administration of 2 ratio groups(1 : 5 and 1 : 10) at 3 different doses (0.1, 0.25 and 0.5g/kg per day). MSM stimulated the growth and survival rate of osteoblasts and PDL cells more than any other agents. The growth and survival rate were increased as the proportion of safflower seed extract was increased. MCE, SSE, ZML stimulated the ALPase activity of osteoblast and PDL cell in comparison to the negative control group. But all groups of MSM regardless of ratio of safflower seed extract stimulated the ALPase activity than any other agent. The ALPase activity was also increased as the proportion of safflower seed extract was increased. Although MCE, SSE, ZML stimulated the proliferation of osteoblasts. 1 : 5 and 1 : 10 ratio MSM showed significant increase in stimulation of proliferation of osteoblasts. No agent significantly increased proliferation of PDL cells. Significant new bone formation were seen where 1 : 5 ratio, 0.5g/kg group and 1 : 10 ratio, 0.25, 0.5g/kg groups were used. These results show that magnoliae cortex extract and safflower seed extract mixture can potentially increase bone regeneration ability.

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.

Safflower (Carthamus tinctorius L.) is a thistle-like annual plant mainly grown in dry hot climates as an oilseed or birdseed. Traditionally, the oil has mainly been sold in the health food market because it is unsaturated having high linoleic and oleic acid levels. With increased health consciousness in recent years, the oil quality has become a more general health issue. This study was designed to understand whether safflower seed powder has positive effects on the fracture healing in rats. Simple transverse fracture of rat fibula was made with a rotating diamond disc saw. The histologic changes of rats were observed with a scanning electron microscope. The fractured fibulae showed a complete fusion at the fracture site in the 4th to 5th week after a simple transverse fracture. Administration of safflower seed powder facilitated the speed of histologic changes without affecting qualitative changes. These results suggest that safflower seed powder nay have substances that help the fracture healing process.

Safflower has been cultivated in Korea and thought to have excellent effects on bone in oriental medicine and folk remedy and has been taken for a long time. Safflower is thought to be helpful for the development and sustenance of bones according to the result of recent assay of its components. Otherwise, any reliable experimental data have not been suggested so far. We have carried out this study to examine the prophylactic effects of safflower-seed-powder on the prevention of osteoporosis induced by the ovariectomy 12 Weeks-old Sprague-Dawley rats weighing about 230 g was kept in the experimental condition and used in this study. Animals were taken 0.3 g of safflower-seed-powder once a day for 1, 3, 5, and 7 weeks after ovariectomizing both ovaries and observed the fine structure of tibia. Tissues were fixed with traditional SEM preparation methods and decalcified for 10 hours with 10% nitric acid and dehydration, drying, and gold-coating were followed by the routine procedures and observed with scanning electron microscope (Hitachi, S-450). Loss of bone was started just after ovariectomy and thickness of bone from the medullary cavity to the compact bone was reduced and the extension of medullary cavity was serious in the control group of 7 weeks. Experimental groups taken safflower-seed-powder showed similar findings from 1 week to 7 weeks. These results suggest that the safflower-seed-powder is thought to be efficient for the prevention of osteoporosis owing to the deficiency of female sex hormone.

This study was done to investigated the phytosterol compositions of safflower (Carthamus tinctorius L.) seed. The phytoestrogen activity was also determined using CAT-ELISA Kit in ethanol extract of safflower seed. The phytosterol of safflower seeds was identified using gas chromatography-mass spectrometry after saponification of the oils. The phytosterol content and composition of safflower seed oils were 4% and identified stigmast-5-en-3-ol (3$\beta$, 24S)-form, ${\gamma}$-sitosterol (clionasterol) with Wiley MS spectrum library. The synergistic effect of human estrogen receptor (hER) has been investigated using a minimal chimeric promoters composed of the TATA region of the adenovirus-2 major late promoter (A22MLP) and two consensus perfectly polindromic Xenopus vitellogenin A2 gene estrogen responsive elements (XVEREl19). Transient transfection experiments in tile human breast adenocarcinoma cell line MCF-7, which is known to express the estrogen receptor endogenously, revealed that phytoestrogen from Carthamus tinctorius L. acts as estrogen. We have observed the transcriptional activities stimulated methanol and ethanol extract of safflower seed in MCF-7, were 0.43 and 0.37 respectively, compared to that by $\beta$-estradiol as 1.0. Our data showed that safflower seeds have estrogenic activity methanol and ethanol extracts and ethanol lower than that of $\beta$-estradiol. This result provides the first evidence that the beneficial effect of safflower seeds may be mediated, at least in part, by the stimulating effect of phytoestrogen ell bone-protecting.

This study was carried out to investigate the effects of Korean safflower(Carthamus. tinctorious L.) seed powder supplementation on bone metabolism during the recovery of rib-fracture induced by surgical operation in rats. Male Sprague-Dawley rats of 10 weeks old, weighing 370$\pm$5g, were divided into two groups after arrival : the control group(C group, AIN-76 semifurified diet) and safflower seed group(S group, AIN-76 semifurified diet+10% safflower seed powder). They were fed experimental diets for 12 days before the rib fracture operation and for 30 more days after the operation. A number 9 rib was fractured surgically and sham-operation was also performed. After the rib-fracture operation, rats were sacrificed on the 8th, 11th, 16th, 21st, and 30th day, respectively. The body weights were decreased on the 8th day after operation in both groups but recovered gradually thereafter. The fractured sections of the S group were more strongly adhered and more rapidly repaired than those of C group. Effects of safflower seed powder supplementation on indices of bone metabolism during the repairing of rib-fracture can be summarized as following. There were no differences between C and S group. In the levels of PTH and calcitonin, which regulate the concentration of plasma calcium. However, PTH level on the 8th day was significantly higher than that on the 16th day in control group. There were also no differences between groups or within groups in the levels of calcitonin. Osteocalcin levels, one of the bone-formation indices, were similar in two groups. Activities of total-ALP in plasma were highest at the 8th day in both groups and decreased thereafter, except on the 30th day in control group. The activities of bone-specific ALP that is directly related to bone calcification, showed higher levels in the S group than in the C group throughout the experimental period. They were significantly increased in the S group on the 11th, 16th, and 21st days. In comparisons of plasma calcium and phosphate levels, Ca levels were tended to be lower in the S group than in the C group and P levels showed the opposite trend. It seems that the fractured ribs were more rapidly repaired in rats supplemented with safflower seed powder than in control rats, possibly due to stimulation of bone calcification from increased activity of bone-specific ALP.

A study was carried out to investigate the effects of safflower seed powder on the improvement of lipid metabolism in high fat and high cholesterol fed rats. Male Sprague Dawley rats of 10 weeks old, weighing 325$\pm$5g, were divided into two groups; the control group(C group, high fat(10% lard) and high cholesterol(1% cholesterol)) and safflower seed group(S group, 10% safflower seed powder), they were fed experimental diets for 6 weeks. Food intake, body weight gains and organ weight had little differences between the groups. Concentration of lipoprotein in serum was remarkably lower in S group than in C group. Serum cholesterol levels were significantly lower in S group(72.94$\pm$4.08 mg/dl) than in C group(89.41$\pm$4.19mg/dl). The level of serum HDL cholesterol was higher in S group than in C group. The level of serum LDL C was significantly lower in S group than in C group. The ratio of HDL cholesterol to total cholesterol were higher in the S group than in the C group, too. The value of atherogenic index(AI) was determined to be low in S group. The content of liver triglyceride and cholesterol in the S group was lower than that of C group. ACAT activities which involves in cholesterol esterification in liver, was not significantly different between two groups.
