  • Objectives : The purpose of this study was to investigate the anti-caner effect of cobrotoxin on the prostatic cancer cell line(PC-3). Methods : After the treatment of PC-3 cells with cobrotoxin, we performed fluorescence microscope, MTT assay, Western blotting, Flow cytometry, PAGE electrophoresis and Surface plasmon resonance analysis to identify $NF-{\kappa}B$ the change of calcium and NO. Results : 1. The expression of $NF-{\kappa}B$ was decreased at 1nM and It·as decreased significantly at 2, 4, 8nM. 2. $I{\kappa}B,\;NF-{\kappa}B$ inhibitor, was decreased significantly at 8nM and $p-l{\kappa}Ba$, phosphrylation of $I{\kappa}B$, was decreased significantly at all concentrations of cobrotoxin. 3. The expressions of p50 and p65 were decreased significantly and dose-dependently at 1, 2, 4, 8nM. 4. The expression of p53 was increased significantly at 1, 2, 4, 8nM. 5. The calcium concentration in cell wasn't changed at 1, 2, 4, 8nM, but was increased dose-dependently at 30, 70, 130, 250nM comparing with lower dose of cobrotoxin. 6. The NO concentration in cell was increased significantly at 1, 2, 4, 8nM. 7. In immunochemical staining, we found that cobrotoxin-immunochemical complex move into intracellular space dose-dependently. Conclusion : These results indicate that cobrotoxin has anti-cancer effects by inducing apoptosis.

  • BACKGROUND/OBJECTIVES: Platycodon grandiflorum (PG), an oriental herbal medicine, has been known to improve liver function, and has both anti-inflammatory and antimicrobial properties. However, little is known about the immune-enhancing effects of PG and its mechanism. In this study, we aimed to investigate whether fermented PG extract (FPGE), which has increased platycodin D content, activates the immune response in a murine macrophage cell line, RAW 264.7. MATERIALS/METHODS: Cell viability was determined by Cell Counting Kit-8 assay and the nitric oxide (NO) levels were measured using Griess reagent. Cytokine messenger RNA levels of were monitored by quantitative reverse transcription polymerase chain reaction. To investigate the molecular mechanisms underlying immunomodulatory actions of FPGE in RAW 264.7 cells, we have conducted luciferase reporter gene assay and western blotting. RESULTS: We found that FPGE treatment induced macrophage cell proliferation in a dose-dependent manner. FPGE also modulated the expression of NO and pro-inflammatory cytokines, such as tumor necrosis factor-α, interleukin (IL)-1β, and IL-6. The activation and phosphorylation levels of nuclear factor kappa B (NF-κB) were increased by FPGE treatment. Moreover, 5-aminoimidazole-4-carboxamide ribonucleotide, an activator of AMP-activated kinase (AMPK), significantly reduced both lipopolysaccharides- and FPGE-induced NF-κB reporter gene activity. CONCLUSIONS: Taken together, our findings suggest that FPGE may be a novel immune-enhancing agent acting via AMPK-NF-κB signaling pathway.

  • Primary malignant lymphoma of the lung is a very rare disease, which consists of 0.34% of entire malignant lymphoma. The majority are low-grade B-cell tumors, and because of their morphological peculiarities and overall excellent prognosis, many cases, like many other extranodal lymphomas, have been mislabelled as "pseudolymphomas" in the past. For these reasons their true incidence is difficult to estimate. An incidentally discovered mass in the right middle lobe of a 36-year-old woman was operated on November 9, 2001 at Hanyang University Hospital. A right upper lobectomy was done and the pathologic diagnosis of extranodal marginal zone B-cell lymphoma of MALT type was made.

  • In order to evaluate the antiallergic effects of Kamiyukgunja-tang (KYGJT), studies were done. We measured the cytotoxic activity for lung fibroblast cell, cytokines transcript expression, production of INF-γ, IL-10, IL-4, GM-CSF, IL-1 β, TNF-α. IL-5 proliferation of B cell in anti-CD40mAb plus r1L-4 stimulated murine splenic B cells. The results were obtained as follows : 1. KYGJT was not showed cytotoxicity in the fibroblast lung cell. 2. KYGJT increased the gene synthesis of INF-γ, IL-10, GM-CSF(m-RNA). 3. KYGJT decreased the gene synthesis of IL-1β, IL-4, TNF-α, IL-5(m-RNA). 4. KYGJT decreased the appearance of TNF-α significantly. 5. KYGJT decreased the appearance of IgE significantly. 6. KYGJT decreased the proliferation of B cell significantly. 7. KYGJT decreased the appearance of Histamin Release Production significantly. The facts above prove that KYGJT is effective against the allergy. Thus. I think that we should study on this continuously

  • In order to investigate the distribution of dominant Bifidobacterium species in intestinal microflora of Korean adults and seniors, SDS-PAGE profiles of whole cell proteins were used for the identification of bifidobacteria. To confirm the reliability of SDS-PAGE, the Bifidobacterium species identified by SDS-PAGE of whole cell proteins were validated by using 16S rDNA sequencing analysis. The results of SDS­PAGE corresponded well with those determined by the analysis of 16S rDNA sequencing. Based on the analysis of SDS-PAGE patterns on unidentified fecal strains which showed positive in fructose-6-phosphate phosphoketolase activity, B. adolescentis, B. longum, and B. bifidum were identified in the feces of adults, and B. adolescentis, B. longum, B. bifidum, B. breve, and B. dentium were identified in those of seniors. In most of the fecal samples tested, the predominant Bifidobacterium species consisted of only a few species, and differences in the distribution and numbers of Bifidobacterium species were observed between adults and seniors. B. adolescentis and B. longum were found to be the most common species in feces of adults, but not in seniors. Accordingly, the distribution and abundance of bifidobacteria in the human intestinal microflora varied depending on the age of hosts.

  • Angiocentric T-cell lymphoma is a rare form of peripheral T-cell lymphoma. The disease typically manifests clinically as an aggressive, progressively destructive disorder often with a fatal outcome. It is the aim of the present paper to derive further studies evaluating the effectiveness of Korean traditional medicine on angiocentric T-cell lymphoma with intra-abdominal metastasis. A patient with high fever, weight loss, night sweat and general weakness(B symptoms) was diagnosed as angiocentric T-cell lymphoma and chemotherapy was done more than 10 times. But the response to chemotherapy was poor, finally the lymphoma involved liver and spleen. The abdominal CT showed the hepatosplenomegaly, diffuse lymphoma of liver and spleen, massive ascites, minimal pleural effusion. Then the patient gave up the chemotherapy and only herb medications (Bohyunsoamtang-A,B) were administered. The ascites, high fever and hepatosplenomegaly gradually reduced to normal. He survived for 7 years after first diagnosis, which is much longer than average survival time in angiocentric T-cell lymphoma with B symptoms. This case may give us a possibility of that Korean traditional herb medications offer potential benefits for patients with angiocentric T-cell lymphoma, and more researches are needed.
