  • The chemical compositions of the seeds of the safflower (Carthamus tinctorius L.) plant were evaluated to determine possible compound having proliferative effects on human osteoblast cells. Three-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT) test and alkaline phosphatase (ALP) activity were used to assess the effects of the isolates on the human osteoblast-like line (Saos-2). Activity guided fractionation led to the isolation of ALP activating lignin and alkaloid glycosides through the extraction of the seeds, solvent partitioning and repeated silica gel and octadecyl silica (ODS) column chromatographic separations. The data from Nuclear Magnetic Resonance (NMR), Mass (MS), and Infrared (IR) analyses enabled the determination of the chemical structure and characterization of two compounds as a tracheloside and an N-(p-coumaroyl)-serotonin mono-${\beta}$-D-glucopyranoside. These two compounds showed respectively $149.2{\pm}4.2$ and $138.9{\pm}3.5%$ ALP activity compared to the control when evaluated at a concentration of $100\;{\mu}g/mL$.

  • This study examined the growth effects of yeast hydrolysate (YH) and a traditional Korean herbal mixture (HM, a mixture of safflower seed and gasiogapi extract). Three-week old male SD rats were divided into the following five groups: negative control (saline), positive control (foremilk 0.5 g/kg/day), YH (YH 0.5 g/kg/day), HM (HM 0.2 g/kg/day), and YH+HM (YH 0.5 g/kg/day and HM 0.2 g/kg/day). Tibia bone length was 9.22 mm in the normal control rats, while both the YH and YH+HM groups had significantly longer tibia bones than the control rats (9.75 mm and 10.46 mm, respectively). The proximal epiphyses of YH, HM, and YH+HM measured 0.75, 0.70, and 0.75 mm, respectively, while the length in the control group was 0.50 mm. Plasma insulin growth factor-1 (IGF-1) level was slightly higher in the YH group (1.36 mg/mL) than in the control rats (1.29 mg/mL), but the difference was not significant. Plasma IGF-1 level was significantly increased in the HM (1.49 mg/mL) and YH+HM (1.53 mg/mL) groups compared to the control group (1.29 mg/mL). Growth hormone (GH) levels in YH (17.45 ng/mL), HM (15.49 ng/mL), and YH+HM (16.07 ng/mL) were significantly different compared to the control group (3.63 ng/mL).

  • We have previously demonstrated that phytoestrogens isolated from safflower seeds significantly attenuated bone loss in ovariectomized rats, and directly stimulated proliferation and differentiation of cultured osteoblastic cells. In an attempt to elucidate underlying cellular mechanisms, in the present study we investigated effects of $17{\beta}-estradiol\;(E_2)$ and phytoestrogens such as matairesinol and acacetin, a type of lignan and flavonoid, respectively, on activation of mitogen activated protein (MAP) kinases, extracellular signal-regulated kinase 1 (ERK1) and ERK2, in cultured osteoblastic ROS 17/2.8 cells. Western blot analysis with anti-MAP kinase antibody showed that a wide range concentrations $(10^{-14}\;to\;10^{-6}\;M)\;of\;E_2$ as well as both phytoestrogens induced rapid and transient activation of ERK1/2 through phosphorylation within minutes. Maximum activation of MAP kinases by $E_2$ and phytoestrogens were observed at 10 and 15 min, respectively. $E_2-induced$ phosphorylation of ERK1/2 returned to the control level at 30 min, whereas phytoestrogen-induced phosphorylation was maintained at high level until 30 min. PD-98059, a highly selective inhibitor of MAP kinase, prevented phosphorylation of ERK1/2 in the cells treated either with $E_2$ or phytoestrogens. To examine a possible involvement of estrogen receptor in the activation process of MAP kinase, Western blot analysis was performed in the presence and absence of the estrogen receptor antagonists, ICI 182,780 and tamoxifen. These antagonists blocked MAP kinase phosphorylation induced not only by $E_2,$ but also by the phytoestrogens. To the best our knowledge, this study is the first to demonstrate that phytoestrogens such as flavonoid and lignan extracted from safflower seeds produce a rapid activation of MAP kinase, at least partially via membrane estrogen receptor of the cultured osteoblastic cells.

  • 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.

  • We recently extracted lignans such as matairesinol and 2-hydroxyarctigenin from safflower seeds and found that they exhibit a potent cytotoxic effect on human promyleocytic leukemia HL-60 cells. In this study, we investigated whether mechanisms of the matairesinol-induced cell death are associated with the programmed cell death, apoptosis. Matairesinol dose-dependently reduced viability of HL-60 cells with an IC/sun 50/ value of 60 $\mu$M. Staining of cells with Hoechst 33342 revealed distinct morphological features of apoptosis, such as the nuclei broken into chromatin containing fragments of various sizes in the cells exposed to 100 $\mu$M matairesinol for 24 hr. Agarose gel electrophoresis of DNA from the cells treated with matairesinol showed internucleosomal DNA degradation into oligonucleosomal sizes. DNA ladder like patterns were easily detected after treatment with matairesinol concentrations ranging from 10 to 100 $\mu$M after 24 hr. In cells treated with 100 $\mu$M matairesinol for differing time periods, the DNA ladder was detectable from 6 hr onward. A time course histogram of the DNA content analyzed by flow cytometry revealed a rapid increase in subdiploid cells and a concomitant decrease in diploid cells exposed to 100 $\mu$M matairesinol. These results indicate that matairesinol-induced HL-60 cell death was due to the DNA damage and apoptosis.

  • 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.
