This study was peformed to elucidate the effects of antler, red ginseng, safflower seed, ipriflavone and estrogen on ovariectomized rats. The rats were fed with Ca and P deficient diet for five weeks to induce osteoporosis. After this period, these animals were fed with normal for and treated every other day with antler(600mg/kg, PO), red ginseng(200mg/kg, PO), safflower(200mg/kg, PO), ipriflavone(80mg/kg, PO) and estrogene(400$\mu\textrm{g}$/kg, IM) for S weeks. During the treatment, the rats were examined for body, organ, femur and femur ash weights. And electron-microscopical examinations were also performed on femora. The results are summarized as follows : 1. The body weights of the antler, red ginseng, safflower, ipriflavone and estrogen-treated groups after five weeks of treatment, were 303.0$\pm$3.0g, 273.3$\pm$4.4g, 288.3$\pm$5.1g, 300.5$\pm$5.2g, 320.5$\pm$4.2g, respectively. They, except the red ginseng-treated group, were significantly higher than 278.4$\pm$2.7g of normal control group(P<0.05). And the body weight of non-treatment group was 29it.2$\pm$5.5g which was higher than that of control group, too. 2. The weights of left femur after five weeks of treatment were showed 0.83$\pm$0.2g by antler, 0.89$\pm$0.2g by red ginseng, 0.87$\pm$0.2g by safflower 0.83$\pm$0.1g by ipriflavone and 0.78$\pm$0.1g by estrogen-treated group. They were a little lower than 0.97$\pm$0.1g of normal control group. Non-treatment group showed 0.83$\pm$0.1g which was lower than that of control group but not significant. 3. The weights of ashed left femora after five weeks of treatment were showed 0.36$\pm$0.01g by antler, 0.40$\pm$0.01g by red ginseng, 0.41$\pm$0.01g by safflower, 0.36$\pm$0.01g by ipriflavone and 0.35$\pm$0.01g by estrogen-treated group. Those results were significantly lower than 0.43$\pm$0.01g of normal control group. And non-treatment group showed 0.29$\pm$0.01g of femoral ash which was significantly lower than that showed by control group(p<0.05). 4. The femoral Ca contents of the antler, red ginseng, safflower, ipriflavone and estrogen-treated rats were 19.6$\pm$0.7%, 17.8$\pm$1.1%, 18.8$\pm$0.9%, 18.0$\pm$1.1%, 15.3$\pm$1.1%, respectively, after five weeks of treatment. The femoral Ca contents of antler and safflower-treated groups were higher than that of control group which showed 18.2$\pm$0.9% of Ca The non-treatment group, showing 15.3$\pm$0.7%, had significantly lower content of Ca than normal group(p<0.05). 5. The weights of liver, spleen, and kidney in the osteoporosis-induced rats during the treatment with antler, red ginseng, safflower, jpriflavone and estrogen showed not significant changes. 6. The connections among the trabeculae of control group were maintained well, showing no bone loss. However, the connections among the trabeculae of non-treatment group were thinner than those of control group and were almost disconnected and the lacunae were found to be broadened. Antler and safflower-treated group showed only slight changes. The recovery rates were prominent in antler, safflower, estrogen-treated groups but they were insignificant in red ginseng and ipriflavone-treated groups.

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 conducted to examine the effect of polyphenols from safflower seed on HMG-CoA reductase (HMGR) activity, LDL oxidation and Apo A1 secretion from Hep3B cell. The safflower seed polyphenols were matairesinol (Iignan), enterolactone (lignan metabolite), acacetin (flavone) and serotonin derivative. In addition to safflower polyphenols, mevastatin, ${\alpha}-estradiol,\;{\alpha}-tocopherol$ and soy genistein were tested as reference compounds depending on the type of the test. HMGR source was liver microsome obtained from rat fed 2% cholestyramine for 10 days. Inhibition of HMGR activity was greater with mevastatin (53%) than safflower serotonin derivatives (45%), followed by genistein (35%), but was very small with matairesinol, enterolactone and acacetin. LDL oxidation induced by $CuSO_4$ was suppressed by all the test material used in the present study and in the order of safflower serotonin derivatives> matairesinol > ${\beta}-estradiol$ > genistein > acacetin > enterolactone. Apo A1 secretion from Hep3B cell was significantly stimulated by mevastatin, but moderately (p<0.1) by ${\beta}-estradiol$ and genistein as well as enterolactone. These results suggest that the safflower polyphenols improve body lipid status via inhibition of cholesterol synthesis and suppression of LDL oxidation.

we are investigated the anti-inflammatory effects of Safflower and Mother wort Ethanol Complex Extracts(SEC) on lipopolysaccharide (LPS)-activated RAW 264.7 cells. The results demonstrated that pretreatment of SEC(500㎍/mL) significantly reduced NO production by suppressing iNOS protein expression in LPS-stimulated cells. Anti-inflammatory effects by Safflower and Mother wort Ethanol Complex Extracts were observed in the following. Safflower and Mother wort Ethanol Complex Extracts inhibited the translocation of NF-κB from the cytosol to the nucleus via the suppression of IκB-α phosphorylation and also inhibited LPS-stimulated NF-κB transcriptional activity. These findings suggest that Safflower and Mother wort Ethanol Complex Extracts exert anti-inflammatory actions and help to elucidate the mechanisms underlying the potential therapeutic values of Safflower and Mother wort Ethanol Complex Extracts. Therefore, Safflower and Mother wort Ethanol Complex Extracts could be regarded as a potential source of natural anti-inflammatory agents.

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.

Biological activity of phenolic compounds in seeds and leaves of safflower (Carthamu tinctorius L.) were evaluated using several in vitro and in vivo assays. Six phenolic constituents were isolated from the seeds and identified as N-feruloylserotonia, N- (p-coumaroyl)serotonin, matairesinol, 8′-hydroxyarctigenin, acacetin 7-O-$\beta$-D-glucoside (tilianine) and acacetin. Six phenolic compounds exhibited considerable antioxidative activity, and especially two serotonins showed potent DPPH radical scavenging activity and antiperoxidative activity against rat liver microsomal lipid peroxidation induced by the hydroxyl radical generated via a Fenton-type reaction. Additionally, six phenolic compounds possessed comparable cytotoxicity against three cancer cells, Hela cell, MCF-7 and HepG2 cell, and particularly acacetin and its glycosides had the most potent cytotoxicity. Moreover, we found that feeding safflower seeds attenuated bone loss, and lowered levels of plasma and liver lipids in ovariectomized rats. Serotonins, lignans and flavones stimulated proliferation of the osteoblast-like cells in a dose-dependent manner (10$^{-15}$ ~10$^{-6}$ M), as potently as E$_2$ (17$\beta$-estradiol). Particularly, serotonins were mainly responsible for bone-protecting and lipid lowering effects in ovariectomized rats. Meanwhile, eight flavonoids, including a novel quercetin-7-O-(6"-O-acetyl)-$\beta$-D-glucopyranoside and seven kown flavonoids, luteolin quercetin, luteolin 7-O-$\beta$-D-glucopyranoside, luteolin-7-O-(6"-O-acetyl)-$\beta$-D-gluco-pyranoside, quercetin 7-O- -glucopyranoside, acacetin 7-O-$\beta$-D-glucuronide and apigenin-6-C-$\beta$-D-glucopyranosyl-8-C-$\beta$-D-glucopyranoside were first isolated and identified from safflower leaf. Among these flavonoids, luteolin-acetyl-glucoside and $\beta$quercetin- acetyl-glucoside showed potent antioxidative activities against 2-deoxyribose degradation and lipid peroxidation in rat liver microsomes. Luteolin, quercetin and their corresponding glycosides also exhibited strong antioxidative activity, while acacetin glucuronide and apigenin-6, 8-di-C-glucoside were relatively less active. Finally, changes in phenolic compositions were also determined by HPLC in the safflower seed and leaf during growth stages and roasting process to produce standardized supplement powerds. These results suggest that phenolic compounds in the roasted safflower seed and leaf may be useful as potential sources of therapeutic agents against several pathological disorders such as carcinogenesis, atherosclerosis and osteoporosis.

This study was designed to examine effects of the various levels of sardine and safflower oil mix on lipid contents of serveral tissues in dietary hyperlipidemic rats. Experimental oils were 16% butter(control group), 8% butter +8% olive oil(group 2) 8% butter+8% sardine oil(group 3) 8% butter+6% sardine oil+2% safflower oil(group 4), 8% butter+4% sardine oil+4% safflower oil(group 5),8% butter+2% sardine oil+6% safflower oil(group 6) and 8% butter+8% safflower oil(group 7). The diet administered to the male rats of Sprague-Dawley were fed for 4 weeks. In livers, total cholesterol and triglyceride, phospholipid concentrations were lowest in the group 5 and free cholesterol concentrations were lower in the groups 4 and 5, particularly. Total cholesterol and triglyceride concentrations in brain were significantly lower in the group 5 and phospholipids were lowest in the group 3, while free cholesterol were group 7. In testes, total cholesterol and triglyceride, phospholipid, free cholesterol concentrations were lower in the all experimental groups than the control group, but those of kidney were lower in the groups 3, 7 than in the control group. Feeding mixed oil having equal quantity of sardine oil and safflower oil were effective on the reduction of the lipid contents in the principal tissues. It might be due to the effects of appropriate ratios of P/S, 0.85 and n-6/n3-p, 2.85 in the test lipids.

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.

Safflower (Carthamus tinctorius) seeds are wellknown traditional oriental medicines that have long been used for the remedies of blood stasis and bone formation in east Asia. In this study, ethyl acetate (EtOAc) was used for extraction of the main chemical compounds from C. tinctorius seeds. Four major compounds were identified, acacetin, cosmosiin, N-feruloyl serotonin and N-(p-coumaroyl) serotonin. Each compound was evaluated for its inhibitory activity against the inflammatory process of macrophages. All compounds significantly inhibited production of lipopolysaccharide (LPS)-stimulated nitric oxide (NO) and pro-inflammatory cytokines. The protein levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were dramatically decreased by serotonins in a dose-dependent manner in LPS-stimulated RAW 264.7 macrophages. These results suggest that serotonin derivatives from safflower seeds may reduce inflammation-related diseases.

Safflower is a world-wide plant for multiple uses. flower of safflower is honghwa(紅花) which has been used for heart disease in oriental medicine. but its seed was not used in oriental medicine. after the publication of "Shinyak(神藥)" - the late 1980s, its seed(紅花子, hongwhassi) was known as good for bone fracture, osteoporosis and menopausal disorders. so many researchers studied hongwhassi and delivered lots of papers. the concern of each paper is different. this paper is a review paper. this paper studied documentary records about hongwhassi, and analyzed hongwhassi research trend. the trend consists of cultivation, ingredient analysis, osteoporosis, atherosclerosis, periodontal ligament and phytoestrogen. many papers lack of information about plant origin. so this paper supplements the standard form of plant origin(when sowing, where grow up, which direction, what kind etc).
