  • We previously showed that Asb-4 and Asb-17 is uniquely expressed in developing male germ cells. A recent report showed that Asb-9 is specifically expressed in the kidney and testes; however, detailed expression patterns in developing germ cells have not been shown. Northern blot analysis in various tissues demonstrated that mAsb-9 was strongly expressed in the testes. Expression analysis by RT-PCR and Northern blot in developing mouse testes indicates that mAsb-9 is expressed from the fourth week after birth to adulthood, with the highest expression in round spermatids. Expression sites were further localized by in situ hybridization in the testes. Pachytene spermatocytes and spermatids expressed mAsb-9 but spermatogonia and generated spermatozoa did not. This study reveals that mAsb-9 could be a specific marker of active spermatogenesis and would be useful for studies of male germ cell development.

  • Research has established a strong connection between a diet rich in antioxidants and a decreased incidence of cardiovascular disease and cancer. These diets prominently feature fruits and vegetables containing high amounts of vitamins A, B, C and E, carotenoids, and minerals. Different processing conditions for these foods can alter their nutrient complement and potency. This study compared the antioxidant properties of a range of processed fruits and vegetables to see which yielded the highest level of antioxidant activity. We used an acetaminophen-induced oxidative stress mouse model to evaluate the antioxidant effects of extracts of processed apple, pear, carrot, cabbage, broccoli, and radish. Our results showed that the administration of these fruits decreased the expression of oxidative stress indicators such as ALT, AST, catalase, superoxide dismutase, GPx, and 8-OHdG. They also significantly protected mice livers from APAP-induced damage, as shown by histological evaluation. Our results have demonstrated the positive effects of processed fruits and vegetables in a mouse model of oxidative stress.

  • As an attempt to control respiratory disease in swine, specific immunologloblin Ys(IgYs) against bacterial pathogens of the diseases were produced and specificity of the IgYs was analysed with Western blot in the previous studies. In this studies, the immunoprotective effects of produced IgY were evaluated in the mice. Mice were challenged with minimal lethal doses of P multocida 3A and 4D, B bronchiseptica and A pleuropneumoniae serotype 2 after intraperitoneal administration of IgY and the protectivity by IgY was dose-dependent at the concentration of 100, 200 and 400 mg/ml. These results suggested that IgY could be a potential immunoprophylactic candidates against those pathogens in swine and apply and effective source of passive immunity for other disease in animals.

  • Objectives : This study aimed to evaluate the protective effects of Seonpyejeongcheon-tang (SJT) on elastase-induced lung injury. Materials and Methods : The extract of SJT was treated to A549 cells and an elastase-induced lung injury mouse model. Then, various parameters such as cell-based cytoprotective activity and histopathological findings were analyzed. Results : SJT showed a protective effect on elastase-induced cytotoxicity in A549 cells. This effect was correlated with analysis for caspase 3 levels, collagen and elastin contents, protein level of cyclin B 1, Cdk1, and Erk1/2, and gene expression of TNF-$\alpha$ and IL-$1{\beta}$ in A549 cells. SJT treatment also revealed a protective effect on elastase-induced lung injury in mouse model. This effect was evidenced via histopathological findings, including immunofluoresence stains against elastin, collagen, and caspase 3, and protein levels of cyclin B1, Cdc2, and Erk1/2 in lung tissue. Conclusion : These data suggest that SJT has pharmaceutical properties on lung injury. This study thus provides scientific evidence for the efficacy of SJT for clinical application to patients with chronic obstructive pulmonary disease.

  • Adenosine deaminase gene from Nocardioides sp. J-326TK was cloned by polymerase chain reaction using primers (PI, PII and PIII) constructed from the highly conserved amino acid sequences among Escherichia coli, mouse and human. A PCR product of about 800bp, as expected from the sequence of E. coli adenosine deaminase gene, was obtained from Nocardioides sp. J-326TK chromosomal DNA double-digested with EcoRI and Pst I. DNA sequencing of the PCR product after cloning into pT7Blue T-vector shows 99.5% and 98.9% homologies in nucleotide and amino acid sequences, respectively, with the E. coli adenosine deaminase whereas 59.5% and 46.8% homologies with the human adenosine deaminase, indicating the evolutionarily relationship of these organisms.

  • Cisplatin is the most effective and widely used chemotherapeutic agent for many types of cancer. Unfortunately, its clinical use is limited by its adverse effects, notably bone marrow suppression leading to abnormal hematopoiesis. We previously revealed that neuropeptide Y (NPY) is responsible for the maintenance of hematopoietic stem cell (HSC) function by protecting the sympathetic nervous system (SNS) fibers survival from chemotherapy-induced bone marrow impairment. Here, we show the NPY-mediated protective effect against bone marrow dysfunction due to cisplatin in an ovarian cancer mouse model. During chemotherapy, NPY mitigates reduction in HSC abundance and destruction of SNS fibers in the bone marrow without blocking the anticancer efficacy of cisplatin, and it results in the restoration of blood cells and amelioration of sensory neuropathy. Therefore, these results suggest that NPY can be used as a potentially effective agent to improve bone marrow dysfunction during cisplatin-based cancer therapy.

  • Effect of brine mineral water(BMW) on contact hypersensitivity reaction(CHR) was estimated using trimellitic anhydride (TMA) induced CHR in the mouse. BMW exhibited potent inhibitory activity on TMA induced CHR. BMW treatment suppressed the ear swelling, and attenuated hyper-activated lymph nodes stimulated by TMA challenge, thereby reduced their weight. The immunological index was analyzed after BMW administration in CHR. The level of serum IgE was significantly down regulated after BMW treatment. Furthermore, BMW showed inhibitory property of cytokine production. BMW treatment suppressed not only Th2 type cytokine, IL-4 but also pro-inflammatory cytokines such as TNF-${\alpha}$ and IL-6. From the histological analysis, the inflammatory context appeared by atopic dermatitis lesion after challenging with TMA are diminished by BMW treatment. Our results suggest that BMW may attenuate the development of CHR, and can be available for functional ingredient.

  • Background: Cigarette smoke (CS) is considered a principal cause of chronic obstructive pulmonary disease (COPD) and is associated with mucus hypersecretion and airway inflammation. Ginsenoside compound K (CK), a product of ginsenoside metabolism, has various biological activities. Studies on the effects of CK for the treatment of COPD and mucus hypersecretion, including the underlying signaling mechanism, have not yet been conducted. Methods: To study the protective effects and molecular mechanism of CK, phorbol 12-myristate 13-acetate (PMA)-induced human airway epithelial (NCI-H292) cells were used as a cellular model of airway inflammation. An experimental mouse COPD model was also established via CS inhalation and intranasal administration of lipopolysaccharide. Mucin 5AC (MUC5AC), monocyte chemoattractant protein-1, tumor necrosis factor-α (TNF-α), and interleukin-6 secretion, as well as elastase activity and reactive oxygen species production, were determined through enzyme-linked immunosorbent assay. Inflammatory cell influx and mucus secretion in mouse lung tissues were estimated using hematoxylin and eosin and periodic acid-schiff staining, respectively. PKCδ and its downstream signaling molecules were analyzed via western blotting. Results: CK prevented the secretion of MUC5AC and TNF-α in PMA-stimulated NCI-H292 cells and exhibited a protective effect in COPD mice via the suppression of inflammatory mediators and mucus secretion. These effects were accompanied by an inactivation of PKCδ and related signaling in vitro and in vivo. Conclusion: CK suppressed pulmonary inflammation and mucus secretion in COPD mouse model through PKC regulation, highlighting the compound's potential as a useful adjuvant in the prevention and treatment of COPD.

  • PURPOSE. The aim of present study was to identify characteristic and response of mouse bone marrow (BM) derived low-adherent bone marrow mesenchymal stem cells (BMMSCs) obtained by quantification of extracellular matrix (ECM). MATERIALS AND METHODS. Non-adherent cells acquired by ECM coated dishes were termed low-adherent BMMSCs and these cells were analyzed by in vitro and in vivo methods, including colony forming unit fibroblast (CFU-f), bromodeoxyuridine (BrdU), multi-potential differentiation, flow cytometry and transplantation into nude mouse to measure the bone formation ability of these low-adherent BMMSCs. Titanium (Ti) discs with machined and anodized surfaces were prepared. Adherent and low-adherent BMMSCs were cultured on the Ti discs for testing their proliferation. RESULTS. The amount of CFU-f cells was significantly higher when non-adherent cells were cultured on ECM coated dishes, which was made by 7 days culturing of adherent BMMSCs. Low-adherent BMMSCs had proliferation and differentiation potential as adherent BMMSCs in vitro. The mean amount bone formation of adherent and low-adherent BMMSCs was also investigated in vivo. There was higher cell proliferation appearance in adherent and low-adherent BMMSCs seeded on anodized Ti discs than machined Ti discs by time. CONCLUSION. Low-adherent BMMSCs acquired by ECM from non-adherent cell populations maintained potential characteristic similar to those of the adherent BMMSCs and therefore could be used effectively as adherent BMMSCs in clinic.

  • Mahwang-Shin-Gung-San has been found inhibiting the mast cell-mediated anaphylactic reaction. This report describes an inhibitory effect of Mahwang-Shin-Gung-San (MSGS) on the immediate-type cutaneous allergic reactions. MSGS has concentration -dependently inhibited the ear swelling response induced by compound 48/80 in mouse by intradermal injection. The mast cells in mouse ear tissue undergone ear-swelling response by compound 48/80 were stained by alcian blue/nuclear fast red. MSGS significantly inhibited the compound 48/80-induced degranulation from mast cells in ear tissue. MSGS concentration-dependently inhibited the histamine release from the rat peritoneal mast cells (RPMC) by compound 48/80. We also studied the effect of MSGS on mast cell-dependent passive cutaneous anaphylaxis (PCA) activated by dinitrophenyl IgE antibody. MSGS showed potent inhibition of PCA by oral administration. These results indicate that MSGS inhibits immediate-type allergic reactions by inhibition of mast cell degranulation in vivo and in vitro.
