The present study was designed to explore the antioxidant effect of Bamboo powder and its immunoreactivity in pigs. We investigated the functional properties of Bamboo extracts by means of measuring the contents of total polyphenols and flavonoid as well as determining ABST, DPPH radical scavenging activity, and hydroxyl radical scavenging activity and anticancer activity. The total phenolic compound and flavonoids contents of Bamboo extracts were 171.25 mg/g and 127.5 mg/g, respectively. The DPPH radical, hydroxyl radical, ABST radical scavenging activity of Bamboo extracts were 17.3%, 12.5% and 21.5%, respectively. Evidenced by MTT and cell cycle assay, Bamboo dose-dependently inhibited the cell proliferation and induced G0/G1-phase arrest in CHO cells at concentrations of 100, 250, and 500 ${\mu}g/ml$ Bamboo extracts. More than 80% of apoptotic cells were observed by staining with annexin V in 500 ${\mu}g/ml$ Bamboo-treated CHO cells, indicating that Bamboo had potent anticancer activities. Next, to investigate the effect of Bamboo on cytokine, immunoglobulin concentration, and blood compositions, flatting pigs were fed with Bamboo powder for 38 days. Flatting pigs were divided into 4 groups; basal diet (control), basal diet supplemented with 1% Bamboo powder (T1), 2% Bamboo powder (T2), and 3% Bamboo powder (T3). The level of hemoglobin increased in the all Bamboo-fed groups compared with the normal control group. In particular, platelet levels in the all Bamboo-treated groups increased by approximately 90% compared with the levels from pig on a normal control. Serum levels of immunoglobulins (IgG, IgA) in the pigs fed Bamboo powder were modestly increased, and the interferon-${\gamma}$ level also was strongly increased in 2% or 3% Bamboo-fed groups compared with the levels in control groups. Together, these results demonstrated that Bamboo extracts had an effective capacity of scavenging for ABTS, DPPH, and hydroxyl radicals and showed correlation with potent phenol and flavonoid contents, thus suggesting its antioxidant potential. Moreover, administration of Bamboo in 2~3% improved blood parameters and platelets, and especially immunity-related ones such as IgG, IgA, and interferon-${\gamma}$, leading to be potential feed additives in flatting pigs.

This study was conducted to evaluate the effects of Zizyphus vulgaris supplementation on growth performance, blood cortisol and meat quality characteristics in finishing pigs. The total of thirty-six [Duroc${\times}$Yorkshir${\times}$Landrace] pigs ($91{\pm}2.11$ kg average initial body weight) were used in a 30-days assay. Dietary treatments included 1) CON (basal diet), 2) T1 (basal diet for 15 days and 0.1 % Zizyphus vulgaris for 15 days) and 3) T2 (0.1 % Zizyphus vulgaris for 30 days). The ADG (Average daily gain), ADFI (Average daily feed intake) and ADG/ADFI during the feeding period were not significantly differences among the treatments (p>0.05). Backfat thickness of pigs fed CON was higher than those of T1 and T2 (p<0.05). The appearance rate of A or B carcass grade was in T1 (74%) and T2 (84%) was significantly higher than that in CON (58%) (p<0.05). Pigs fed Zizyphus vulgaris 0.1 % for 30 days tended to decrease on blood cortisol compared with pigs fed CON and T1. But, there was not significantly difference among the treatments (p>0.05). The Hunter's L/sup */ (lightness) value of loin in the pork fed CON was higher than that of loin in the pork fed T1 and T2 (p<0.05). After 7 days, the L/sup */ value of loin in the pigs fed T2 was higher increased than that of pigs fed T1 and CON (p<0.05). However, a/sup */ and b/sup */ values were not affected by dietary Zizyphus vulgaris (p>0.05). There were not found remarkable differences in sensory properties (marbling, firmness and color) among the treatments. The results from the present study suggest that Zizyphus vulgaris could be a effective feed additive to improve meat quality of pigs. However, further research is needed to investigate effects of carcass characteristics.
The therapeutic potential of phosphodiesterase 4(PDE4) inhibitors in inflammatory diseases including some autoimmune diseases has been explored recently with some hopeful results. These PDE4 inhibitors are thought to show their anti-inflammatory effect by down-regulating tumor necrosis factor-a (TNF-$\alpha$) production in lymphocytes and macrophages. A high concentration of TNF-$\alpha$has been found in rheumatoid arthritis (RA) synovium and reducing TNF-$\alpha$using biological agents was proven to be an effective RA treatment. To test the possibility of using PDE4 inhibitors for RA treatment, the effects of a newly synthesized PDE4 inhibitor, DWP205505, on TNF-$\alpha$ and IL-10 production was tested in cells isolated from normal peripheral blood and rheumatoid arthritis synovial fluid. Cytokine production was assayed at the protein level by sandwich enzyme-linked immunosorbent assay (ELISA) and at the mRNA expression level by semi-quantitative RT-PCR. Another PDE4 inhibitor, RP73401, was used for comparison. DWP205505 and RP73401 had no harmful effect on cell viability up to 10 $\mu$M concentration during the 24 h culture period. DWP205505 as well as RP73401 significantly reduced TNF-$\alpha$ secretion from lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (pBMC) and synovial fluid mononuclear cells (SFMC). The effect of DWP205505 or RP73401 treatment on the mRNA expression of TNF-$\alpha$ was also studied in LPS-stimulated PBMC and SFMC. TNF-$\alpha$ mRNA expression was increased by LPS stimulation and both of the PDE4 inhibitors suppressed TNF-$\alpha$ mRNA expression. For interleukin-l0 (IL-l0), a little different results were obtained from PBMC and SFMC; IL-l0 secretion was unaffected by LPS stimulation and only minimally affected by both of the PDE4 inhibitors in PBMC. In unstimulated SFMC, DWP205505 and RP73401 slightly enhanced IL-10 secretion, while they reduced IL-l0 secretion from LPS-stimulated SFMC where IL-l0 secretion was a lot higher than unstimulated SFMC. These results suggest that the newly synthesized PDE4 inhibitor DWP205505 may have anti-rheumatoid arthritis activity.

Background : Cyclosporin A(CsA) and tacrolimus(FK506) have been widely used as immunosuppressants. The effects of CsA, or FK506, on the $I{\kappa}B/NF-{\kappa}B$ pathway have been shown to vary according to the cell type. However, their effects on the $I{\kappa}B/NF-{\kappa}B$ pathway have not been reported in bronchial epithelial cells. In this study, the effects of CsA and FK506 on the $I{\kappa}B/NF-{\kappa}B$ pathway in bronchial epithelial cells, monocytes, lymphocytes and alveolar macrophages were evaluated. The relationship between their effects on the $I{\kappa}B/NF-{\kappa}B$ pathway and $I{\kappa}B$ kinase(IKK) activity was also investigated. Methods : BEAS-2B and A549 cells, pulmonary alveolar macrophages, peripheral blood monocytes and lymphocytes were used. The cells were pre-treated with CsA, or FK506, for various time periods, followed by stimulation with TNF-${\alpha}$, LPS or IL-$1{\beta}$. The $I{\kappa}B{\alpha}$ expressions were assayed by Western blot analyses. The IKK activity was evaluated by an in vitro immune complex kinase assay, using GST-$I{\kappa}B{\alpha}$ as the substrate. Results : Neither CsA nor FK506 affected the level of $I{\kappa}B{\alpha}$ expression in any of the cell types used in this study. CsA pre-treatment inhibited the TNF ${\alpha}$-induced $I{\kappa}B{\alpha}$ degradation in bronchial epithelial cells. In contrast, the TNF ${\alpha}$-induced $I{\kappa}B{\alpha}$ degradation was not affected by FK506 pre-treatment. However, FK506 suppressed the cytokine-induced $I{\kappa}B{\alpha}$ degradation in the pulmonary alveolar macrophages, peripheral blood monocytes and lymphocytes. The inhibitory effect of CsA, or FK506, on $I{\kappa}B{\alpha}$ degradation was not related to IKK. Conclusions : CsA and FK506 suppressed the $I{\kappa}B{\alpha}$ degradation in bronchial epithelial cells, monocytes, lymphocytes and alveolar macrophages, so this may not be mediated through IKK.
International index of erectile function (IIEF) has a high sensitivity and specificity for the evaluating treatment of erectile dysfunction. IIEF was used to evaluate on an international level the effectiveness of red ginseng on patients with erectile dysfunction and determine its possible development as a natural drug. 50 patients with erectile failure who were 20 years or older and without organic cause were randomly divided into two groups. Group 1(25 patients) received red ginseng 600mg three times a day and group 2 (25 patients) received placebo in the same fashion for 8 weeks. Each group was evaluated with IIEF at the start and end of therapy. Of the 50 patients 47 (group 1 24, group 2 23) who completed the 8 week therapy were evaluated. The mean age and symptom duration of the patients was 45.7$\pm$8.7 (27-68) and 6.2$\pm$5.6(1-29) years, respectively. Patient age, symptom duration. marriage status, marriage duration, partner age were not statistic significance between the two groups (p>0.05). Blood chemistry, urinalysis, and hormonal assay did not reveal difference between the two groups. primary efficacy (erectile rigidity and its maintenance) and all domains in secondary efficacy were significantly better after therapy in group 1 compared to those of group 2 (p<0.05) except for frequency of sexual desire, degree of sexual desire, and frequency of intercourse trial (p>0.05). Group 1 patients were significantly more satisfied after treatment compared to group 2 patients with 58.3% (14/24)and 26.1%(6/23) satisfaction rates, respectively. There were no adverse reactions or complications with ginseng adiminstration. Further study into the effects of saponin and ginsenoside that are the main substances in ginseng for erectile dysfunction is needed. In addition, its possible additive effect with ginseng and sildenafil should be elucidated in the future.
The experiment was conducted to estasblish the large scale production of anti-serum against chicken IgG and to profile the developmental changes of serum IgG levels during all the feeding period(from hatching to 7 weeks of age) in broiler chicks. Blood sample were taken from Hubbard chicken hi-daily or /and weekly during the experimental period. The pure IgG was isolated from ammonium sulfate treated chicken serum by ion exchange chromatography. The quantitative assay of serum IgG were carried by RID method. It was observed that IgG concentrations were showed the highest at hatching(4.25 $m\ell$/$m\ell$), after that dicreased rapidly, lowest at 2 weeks of age(0.81 $m\ell$/$m\ell$), and gradually increased to 7 weeks of age (2.48 $m\ell$/$m\ell$) There was no differences of IgG level between sex, but the IgG levels of male chicks dicreased more rapidly and increased earlier thereafter than those of females during the first two weeks of agg.
Methicillin-resistant staphylococci (MRS) are emerging as important pathogens in humans and animals worldwide. The aim of this study was to investigate the prevalence of MRS in the racehorse population and in horse-related personnel in Korea. A total of 195 horses and 18 humans (eight veterinarians, three veterinary hospital staff, and seven horse-handlers) from racehorse farms in Korea were included in the study. The samples were collected from nasal cavities using bacterial transport medium and were cultivated on tryptic soy agar with 5% sheep blood for 3 days at $37^{\circ}C$ to confirm the presence of Staphylococcus spp. Presumptive Staphylococcus spp. isolates were identified by 16S ribosomal RNA gene analysis. The coagulase test and oxacillin susceptibility tests were performed using the tube dilution and disk diffusion methods, respectively. The presence of the mecA gene was determined using a polymerase chain reaction assay. Of the 195 horses, 29 (15.6%) yielded 29 MRS isolates. Twelve (66.7%) of the 18 horse-related personnel yielded 12 MRS isolates. All of the MRS isolates from horses or horse-related personnel were identified as methicillin-resistant coagulase-negative staphylococci (MRCNS). The result of this study suggest that the prevalence of MRS increased with the duration of antibiotic use (p = 0.002). This study also provides evidence for the zoonotic transmission of MRCNS between horses and humans, although further investigations are needed.

Objectives : Commiphora myrrha (CM) has been used in traditional medicine for treating disease such as obesity, hyperlipidemia, atherosclerosis, diabetes and osteoarthritis. However, the protective effects of CM on acute pancreatitis (AP) has not been reported. Thus, the aim of this study was to evaluate the protective effects of CM water extract on cerulein-induced AP. Methods : AP was induced in mice via intraperitoneal injection of supramaximal concentrations of the stable cholecystokinin analogue cerulein ($50{\mu}g/kg$) every hour for 6 times. Water extract of CM (0.1, 0.2, or 0.5 g/kg) was administrated intraperitoneally 1 h prior to the first injection of cerulein. The mice were killed at 6 h after the final cerulein injection. Pancreas was rapidly removed for morphologic and histochemical examination, myeloperoxidase (MPO) assay. Blood samples were taken to determine serum amylase and lipase activities. Results : Administration of CM significantly inhibited pancreatic weight/body weight ratio, pancreas histological injury. And CM administration inhibited the serum digestive enzyme elevation such as amylase and lipase on cerulein-induced pancreatitis. In addition, Pancreas MPO activity which indicates neutrophil infiltration was inhibited by CM extract on cerulein-induced pancreatitis. Conclusions : In conclusion, our results could suggest that pre-treatment of CM reduces the severity of cerulein-induced AP. Therefore, CM could be used as a protective agent against AP. Also, this study could give a clinical basis that CM could be a drug or agent to prevent AP.
Many clinical trials have demonstrated the beneficial effects of garlic (Allium sativum) on general cardiovascular health. Aged garlic extract (AGE) is known to display diverse biological activities such as in antioxidant, anti-inflammatory and anticancer activities. However, few studies have been directed on the effect of AGE on cardiovascular function. In this study, we aimed to investigate the effect of AGE and its components on platelet activation, a key contributor in thrombotic diseases. In freshly isolated rat platelets, AGE and its components have shown inhibitory activities on thrombin-induced platelet aggregation. These in vitro results were further confirmed in an in vivo platelet aggregation measurement where tail vein injection of garlic oil and S-Allylmercapto-cysteine (SAMC) significantly reduced thrombin and ADP-induced platelet aggregation. Potential active components for antiplatelet effects of AGE were identified to be SAMC and diallyl sulphide through agonist-induced platelet aggregation assay. These results indicate that aged garlic extract can be a novel dietary supplement for the prevention of cardiovascular risks and the improvement of blood circulation.

This case report describes the increment of regulatory T cells in thyroid carcinoma of a mixed breed dog compared with normal dogs. A mixed breed dog was referred for a submandibular mass and hyperthermia. Right cervical mass was detected during the physical examination and radiography identified right cervical mass suspected thyroid gland. Accurate location and size of mass was confirmed using computed tomography and 3D reconstructed images. After confirmation of mass, surgical resection was performed and evaluation of regulatory T cells in blood of this patient was performed using flow cytometric assay. The percentage of regulatory T cells was 38.28% of all CD4 (+)/CD25 (+) T cells. This result was higher than median percentage of regulatory T cells of healthy 8 beagles ($7.66{\pm}1.65%$ (p<0.01) of all CD4 (+)/CD25 (+) T cells). And masses were confirmed as giant cell thyroid carcinoma based on histopathologic examination. After surgical resection of cervical mass was performed, the owner didn't want chemotherapy. Seven days later, cervical mass came out again. And CBC showed severe leukocytosis (WBC $47.6{\times}10^3/{\mu}L$) and non-regenerative anemia (PCV 21%). Suspected pulmonic metastasis regions became more severe. Finally the dog died of severe anemia and respiratory disorder.
