  • Objectives : The aim of this study was to investigate the anti-obesity potential and mechanisms of action of Rhizoma Atractylodis(RA) herbal acupuncture in high fat diet- induced obese ICR mice. Methods : Sample solutions for herbal acupuncture were prepared from the Rhizoma Atractylodis water extract powder at concentration of 150mg/kg and 300mg/kg with distilled water. Five week-old ICR mice acclimatized to the laboratory environment for 1 week were allocated into four groups: regular diet group (RD), high fat diet group(HFD), groups fed HFD with 150mg/kg RA herbal acupuncture treatment (RAE 150) and with 300mg/kg RA herbal acupuncture treatment(RAE 300). Herbal acupuncture groups were injected with either 150mg/kg or 300mg/kg of Rhizoma Atractylodis(RA) subcutaneously onto both Sinsu($BL_{23}$) alternately on the same time everyday for 30days. Body weight, gross appearance of epididymal fat area, blood glucose, insulin, insulin resistance(HOMA-IR), non-esterified fatty acid, cholesterol, triglyceride, AST, ALT, histological analysis of white adipose tissue, gene expression responsible for adipocyte differentiation and AMPK activation were analyzed. Results : RA herbal acupuncture inhibited the development of weight gain, hyperglycemia, hyperinsulinemia, hyperlipidemia, increases of AST and ALT, and the enlargement of fat cell size induced by HFD. Also, RA herbal acupuncture inhibited the expression of PPAR-${\gamma}$, C/$EBP{\alpha}$, aP2, LPL, FAS, SCD-1 and enhanced the activation of AMP-activated protein kinase. Conclusions : The results of this study demonstrate that RA herbal acupuncture can exert the anti-obesity effect and it is partially mediated by activation of AMPK and inhibition of the gene expressions responsible for adipocyte differentiation. Further studies will be required to ascertain the nti-obesity effect and mechanisms of action of RA herbal acupuncture in animal models and human for aclinical application.

  • This study was conducted to examine the effects of supplementing brown seaweed by-products (BSB) in the diet of ruminants on ruminal fermentation characteristics, growth performance, endocrine response, and milk production in Holstein cows. In Experiment 1, the effects of different levels (0%, 2%, and 4% of basal diet as Control, 2% BSB, 4% BSB, respectively) of BSB were evaluated at 3, 6, 9, 12, and 24 h in vitro batch culture rumen fermentation. The pH tended to be higher for the higher level of BSB supplementation, with the pH at 12 h being significantly higher (p<0.05) than that of the control. The concentration of ammonia nitrogen was lower at 3, 9, 12, and 24 h incubation (p<0.05) compared with the control, and tended to be low at other incubation times. Volatile fatty acid concentration appeared to be minimally changed while lower values were observed with 4% BSB treatment at 24 h (p<0.05). In Experiment 2, effects of levels (0%, 2%, and 4%) of BSB on growth performance, endocrine responses and milk production were studied with Holstein dairy cows during transition. Dry matter intake, daily gain and feed efficiency were not affected by BSB supplementation. The concentration of plasma estrogen for the control, 2% BSB and 4% BSB after three months of pregnancy were 55.7, 94.1, and 72.3 pg/mL, respectively (p = 0.08). Although the differences of progesterone levels between BSB treatments and the control were minimal, the concentration in 4% BSB treatment increased to 157.7% compared with the initial level of the study. Triiodothyronine and thyroxine levels were also higher after both three months and eight months of pregnancy than the initial level at the beginning of the study. In addition, BSB treatments during one month after delivery did not affect daily milk yield and composition. In conclusion, the present results indicate that supplementation of BSB did not compromise ruminal fermentation, and animal performance at lower levels and hence may have potential to be used as a safe feed ingredient in dairy cows.

  • The main goal of this study was to produce transgenic piglets by the method of injection of sperm-mediated exogenous DNA. Spermatozoa (1$\times$106 sperm of final concentration) obtained from caudal epididymis were mixed with pBC1-hEPO (20 ng/${mu}ell$) or pcDNA3 LAC Z (20 ng/${mu}ell$), and followed by electroporation (500 V, 25 ㎌). Matured oocytes having the first polar body and dense cytoplasm were selected and centrifuged at 12,000g for 6 min. After sperm injection, the oocytes were activated electrically (1.7 ㎸/cm, 30 $\mu$ sec, single pulse) in 0.3 M mannitol solution. Eggs injected sperm were cultured in NCSU 23 medium (0.4% BSA) at 39$^{\circ}C$, 5% $CO_2$ in air for 192 h. This study were comprised 3 experiments. Experiment 1 compared the developmental efficiencies between the sperm-injected oocytes (Group 1) and further activated electrically (Group 2). Experiment 2 compared the expression of pcDNA3 LAC Z in the embryos produced by Group 1 and Group 2. Finally, experiment 3 carried out transfer of embryos (1-8 cell stage) transfected with pBC1 -hEPO into surrogate recipients synchronized by injection of combination of PG600 with hCG. The rates of cleavage and development into blastocyst stage in Group 2 were significantly higher than those of Group 1 (71.3% and 28.1% vs. 43.3% and 10.3%, respectively, p<0.05). Thirty (24.2%) out of 124 embryos analyzed in Group 2 were positive by X-gal. Similarly, in Group 1, 16.3% (8/49) were positive. After transfer of 789 embryos to 7 recipient gilts, three out of them examined by ultrasound became pregnant. One recipient is in day 50 pregnancy. On day 54 of gestation, two were carried out uterotomy in order to confirm the pregnancy One had 7 and another had 2 fetuses. We conclude that injection of sperm-mediated gene transfer will be used as a valuable tool for the production of transgenic piglets.

  • FoxO1, FoxO3a and FoxO4 belong to the FoxO gene family, which play important roles in the PI3K/PKB pathway. In this study, we cloned the porcine FoxO1, FoxO3a and FoxO4 sequences and assigned them to SSC11p11-15, SSC1p13 and SSC xq13 using somatic cell hybrid panel (SCHP) and radiation hybrid panel (IMpRH). RT-PCR results showed that these three genes are expressed in multiple tissues. Sequencing of PCR products from different breeds identified a synonymous T/C polymorphism in exon 2 of FoxO3a. This FoxO3a single nucleotide polymorphism (SNP) can be detected by AvaII restriction enzyme. The allele frequencies of this SNP were investigated in Dahuabai, Meishan, Tongcheng, Yushan, Large White, and Duroc pigs. Association of the genotypes with growth and carcass traits showed that different genotypes of FoxO3a were associated with carcass length and backfat thickness between 6th and 7th ribs (BTR) and drip loss (p<0.05).

  • This study was performed to investigate the effect of desalinated underground seawater (named as 'magma seawater', MSW) of Jeju Island in Korea on lipid metabolism and antioxidant activity. MSW was collected from underground of Han-Dong in Jeju Island, and freely given to high fat diet (HFD)-fed C57BL/6 mice for 10 weeks. Although there were no significant differences in the body weight changes and plasma lipid levels, hepatic triglyceride levels were significantly lower in the MSW group than in the normal tap water (TW)-drunken control group. Furthermore, the activity of fatty acid synthase (FAS) was significantly decreased and carnitine palmitoyltransferase (CPT) activity was increased in MSW group compared to TW group. Similarly, real-time PCR analysis revealed that mRNA expressions of lipogenic genes were lowered in MSW groups compared to the control group. In a morphometric observation on the liver tissue, accumulation of fats was remarkably reduced in MSW group. Meanwhile, in vitro assay, tree radical scavenging activity measured by using diphenylpicrylhydrazyl (DPPH) was increased in MSW group. The 2'-7'-dichlorofluorescein diacetate (DCF-DA) staining followed with fluorescent microscopy showed a low intensity of fluorescence in MSW-treated HepG2 cells, compared to TW-treated HepG2 cells, which indicated that the production of reactive oxygen species by tert-butyl hydroperoxide (t-BHP) in HepG2 cells was decreased by MSW treatment. The antioxidant effect of MSW on t-BHP-induced oxidative stress in HepG2 cells was supported by the increased activities of intracellular antioxidant enzymes such as catalase and glutathione reductase. From these results, we speculate that MSW has an inhibitory effect on lipogenesis in liver and might play a protective role against cell damage by t-BHP-induced oxidative stress.

  • Scutellariae Radix (Scu.), one of the immune-regulatory substances, is recognized to play the role in the metabolic process of inflammation, allergy and immunity. It has been traditionally used in the Oriental medicine to treat inflammatory bowel diseases (IBD). The purpose of this study was to evaluate the effects of water extracts of Scutellariae Radix on the spleen lymphocyte immune function in the Balb/c female mice treated with dextran sodium sulfate (DSS) to induce colitis. Water extract of Scutellariae Radix (100 mg/kg) and sulfasalazine (50 mg/kg) were administrated orally for 2 weeks of experimental period. Mice were divided into three experimental groups randomly: DSS group (5% DSS was ad libitum for 5 days) as control group, DSS + Scu. (water extracts of Scutellariae Radix for 2 weeks after 5% DSS was ad libitum for 5 days) as experimental group, and DSS + Sulfasalazine group (Sulfasalazine for 2 weeks after 5% DSS was ad libitum for 5 days) as positive control group. Levels of Ig A, Ig E, CD4$^{+}$, CD8$^{+}$, TNF-$\alpha$ and other cytokines were measured. Treatment of DSS for 5 days induced bowel inflammation and the treatment with Scu. water exteract and sulfasalazine significantly recovered the damage. The length of intestine of DSS group was significantly shorter than that of other groups. The serum and fecal concentration of Ig A of SS + Scu group was higher than those of DSS group. The contents of CD4$^{+}$ T cells was higher in the DSS + Scu. group than the other groups and CD8$^{+}$ T cells was the lowest in DSS + Sulfasalazine group. The Ig A level of cultured supernatant of spleen lymphocyte was the highest, while the Ig E level was the lowest in SS + Scu group. The concentration of TNF-$\alpha$, cytokine secreted from the Th1 cell in the supernatant spleen lymphocyte, was the highest in the DSS group and the lowest in the DSS + Scu. group. The concentration of IFN-${\gamma}$ and ll...-12 was lower in the DSS + Scu. group than those of the other groups. The concentration of IL-4 in the supernatant of spleen lymphocyte was the lowest in the DSS + Scu. group but IL-10 was not significantly different. Based on these findings, water extract of Scutellariae Radix exhibited the inhibitory effect via IL-4 production thereby inhibited the production of Ig E and strengthened immune system, and alleviated injury in DSS- induced colitis mice model.

  • Oligomeric proanthocyanidins (OPCs), classified as condensed tannins, have significant antioxidation, anti-inflammation and anti-cancer effects. This study was performed to investigate the anti-inflammatory effects of OPCs and the mechanism underlying these effects in lipopolysaccharide (LPS)-stimulated bovine mammary epithelial cells (MAC-T). Real-time PCR and ELISA assays indicated that OPC treatment at 1, 3 and 5 ㎍/ml significantly reduced the mRNA and protein, respectively, of oxidant indicators cyclooxygenase-2 (COX-2) (p < 0.05) and inducible nitric oxide synthase (iNOS) (p < 0.01) as well as inflammation cytokines interleukin (IL)-6 (p < 0.01), IL-1β (p < 0.01) and tumor necrosis factor-α (TNF-α) (p < 0.05) in LPS-induced MAC-T cells. Moreover, OPCs downregulated LPS-induced phosphorylation of p65 and inhibitor of nuclear factor kappa B (NF-κB) (IκB) in the NF-κB signaling pathway (p < 0.01), and they inhibited p65 translocation from the cytoplasm to the nucleus as revealed by immunofluorescence test and western blot. Additionally, OPCs decreased phosphorylation of p38, extracellular signal regulated kinase and c-jun NH2-terminal kinase in the MAPK signaling pathway (p < 0.01). In conclusion, the anti-inflammatory and antioxidant activities of OPCs involve NF-κB and MAPK signaling pathways, thus inhibiting expression of pro-inflammatory factors and oxidation indicators. These findings provide novel experimental evidence for the further practical application of OPCs in prevention and treatment of bovine mastitis.
