  • 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.

  • 본 연구는 종계사료 내 홍화씨 및 키토산의 첨가 급여가 산란종계에서 종란 생산성 및 후기 난각질 강화에 미치는 영향을 검토하기 위하여 수행하였다. 54주령 Hy-Line Brown 산란종계 암탉 400수와 수탉 40수를 공시하여 Ca을 3.5%로 수준으로 함유한 실험사료(대조구)에 홍화씨 분말을 0.25% 및 0.50% 수준으로 첨가하거나 키토산을 0.10% 및 0.20% 수준으로 첨가한 총 5개의 실험사료(4반복)를 6주간 급여하였다. 사료섭취량 및 난생산성에서는 처리간에 차이가 없었으나, 종란율은 대조구에 비해 홍화씨 분말 및 키토산을 첨가한 모든 실험구에서 첨가 수준과 관계없이 유의하게 증가하였다(P<0.05). 평균 난각 강도는 홍화씨 분말 및 키토산 첨가에 의해 유의하게 개선되었으며(P<0.01), 난각 두께는 키토산 첨가구가 대조구에 비해 유의하게 높은 것으로 나타났다(P<0.01). 수정율 및 입란대 부화율은 대조구에 비해 키토산 첨가구에서 유의하게 개선되는 결과가 관찰되었다. (P<0.01). 경골 파쇄강도는 처리간에 큰 차이가 없었으나, 경골 내 Ca 및 P 함량은 대조구에 비해 홍화씨 분말 0.5% 첨가구와 키토산 첨가구(T3 및 T4)에서 유의하게 증가하였다. (P<0.01). 혈중 estrogen, calcitonin 및 PTH 등 호르몬 농도에서는 큰 변화가 없는 것으로 나타났다. 상기의 결과로부터 산란종계의 후기 난각질 및 생산성의 개선을 위해서는 사료 내 홍화씨 및 키토산과 같은 Ca의 이용성에 영향을 미치는 성분을 적절히 활용함으로써 후기 난각질과 부화율의 개선을 통해 종란 생산성을 향상시킬 수 있을 것으로 사료된다.
