    • PURPOSE: A bacteriocin produced by Bacillus polyfermenticus showing direct antibacterial action against Helicobacter Pylori as a causative agent of gastritis is provided. Therefore, it can be used in the treatment of acid peptic disease such as gastritis and duodenal ulcers by oral administration. CONSTITUTION: A bacteriocin as an antimicrobial substance produced by Bacillus polyfermenticus controls or eradicates Helicobacter pylori. For an example, Bacillus polyfermenticus is cultured in a TBS(Difco laboratories) medium, Helicobacter pylori(KCTC 2948) is cultured in a Mueller hinton medium added with 10% bovine calf serum at 37deg.C under anaerobic conditions. Helicobacter pylori in the amount of 10¬6 cfu/ml is smeared to a solid medium and cultured, Bacillus polyfermenticus(10 microliter) remaining in a logarithmic growth phase is spotted and cultured. In the test, the inhibiting effect on the growth of Helicobacter pylori is distinctly observed.
    • 目的:提供由芽孢杆菌(polyfermenticus)产生的细菌素,其显示对幽门螺杆菌作为胃炎致病因子的直接抗菌作用。 因此,可以通过口服治疗酸性消化性疾病如胃炎和十二指肠溃疡。 构成:作为抗菌物质的细菌素,由芽孢杆菌多毛属发酵菌控制或根除幽门螺杆菌。 例如,在TBS(Difco实验室)培养基中培养芽孢杆菌,在37℃,在厌氧条件下,在加入10%牛血清的Mueller hinton培养基中培养幽门螺杆菌(KCTC 2948)。 将10〜6cfu / ml的幽门螺旋杆菌涂抹于固体培养基中并培养,保留在对数生长期的培养物(10微升)的芽孢杆菌。 在试验中,幽门螺杆菌生长抑制作用明显。

    • A method for isolating monocyte from peripheral blood mononuclear cell (PBMC) with floating density gradient centrifugation is provided to raise the purity and yield of monocyte by regulating density and osmotic pressure of histopaque or ficoll solution. A method for isolating monocyte from peripheral blood mononuclear cell (PBMC) with floating density gradient centrifugation is centrifuging PBMC using histopaque or ficoll solution. A density and osmotic pressure of histopaque or ficoll solution are 1.071-1.073g/ml and 330-340mOsm, respectively. A method for applying the density and osmotic pressure of histopaque or ficoll with determined figure is mixing PBS and NaCl solution in histopaque or ficoll solution. A dendritic cell is obtained by culturing the isolated monocyte.
