  • Objective: To investigate the diagnostic yield of contrast-enhanced computed tomography (CT) in Crohn's disease (CD) patients presenting with acute severe lower gastrointestinal bleeding (LGIB), and the role of CT in predicting the risk of rebleeding. Materials and Methods: A consecutive series of 110 CD patients presenting with acute severe LGIB between 2005 and 2016 were analyzed. Among them, 86 patients who had undergone contrast-enhanced CT constituted the study cohort. The diagnostic yield of CT for detecting contrast extravasation was obtained for the entire cohort and compared between different CT techniques. In a subgroup of 62 patients who had undergone CT enterography (CTE) and showed a negative result for extravasation on CTE, the association between various clinical and CTE parameters and the risk of rebleeding during subsequent follow-up was investigated using Cox regression analysis. Results: The diagnostic yield of CT was 10.5% (9 of 86 patients). The yield did not significantly differ between single-phase and multiphase examinations (p > 0.999), or between non-enterographic CT and CTE (p = 0.388). Extensive CD (adjusted hazard ratio [HR], 3.27; 95% confidence interval [CI], 1.09-9.80; p = 0.034) and bowel wall-to-artery enhancement ratio (adjusted HR, 2.81; 95% CI, 1.21-6.54; p = 0.016) were significantly independently associated with increased rebleeding risks, whereas anti-tumor necrosis factor-${\alpha}$ therapy after the bleeding independently decreased the risk of rebleeding (adjusted HR, 0.26; 95% CI, 0.07-0.95; p = 0.041). Conclusion: The diagnostic yield of contrast-enhanced CT was not high in CD patients presenting with acute severe LGIB. Nevertheless, even a negative CTE may be beneficial as it can help predict the risk of later rebleeding.

  • Objective: The purpose of experimental study was to prove the effects of Boyangmakseong-bang (BYMSB) treatment on cBSA-induced in a MN mouse model. Methods: We divided mice into 4 groups. The Normal group had no treatment. We used cBSA and induced MN mouse model to the other 3 groups. The Control group was treated with cBSA (9mg/kg i.p) only. The second group, named 'BY-250', was treated with cBSA (9mg/kg i.p) and BYMSB extract (250mg/kg, p.o). The third group, named 'BY-500', was treated with cBSA (9mg/kg i.p) and BYMSB extract (500mg/kg, p.o). After cBSA and BYMSB extract treatment for 4 weeks, the increase in percentage of body weight, proteinuria, serum albumin, total cholesterol, creatinine and BUN of all groups were measured. The CD3+, CD19+, CD4+, CD8+ cell levels of spleen of all groups were analyzed. IgA, IgG, IgM, IL-$1{\beta}$, TNF-${\alpha}$, IL-6 and IFN-${\gamma}$ levels of all groups were gauged. H&E staining, immunofluorescence staining and electron microscopy of kidney were observed. Results: BYMSB showed significant decrease in the 24hrs proteinuria, serum total cholesterol, serum IgG levels and BUN levels, and showed significant increase in the serum albumin levels compared with the control group. BYMSB showed increase in the increasing percentage of body weight and IFN-${\gamma}$ levels compared with the control. BYMSB showed decrease in the CD3+ T cells, CD4+ Th cells, IL-$1{\beta}$, TNF-${\alpha}$ and IL-6 levels, but did not show significant change compared with the control. BYMSB showed considerable decrease in the thickening of the GBM on H&E staining, deposition of IgG on immunofluorescence staining and deposition of electron-density on electron microscopy of kidney compared with the control. Conclusions: According to the above results, it is suggested that BYMSB decreases the symptoms of MN induced by cBSA in a mouse model. Therefore BYMSB seems to be applicable to MN in clinical practice.

  • Absorption of Cadmium(Cd) and Arsenic(As) by lettuce following to the change of polyamine content in lettuce were examined to find the effect of these elements on lettuce growth and on the basic resistance mechanism. As the contents of Cd and As were increased in soil, the contents of these elements were significantly increased in lettuce but lettuce growth was decreased. Sequential fractionation experiment of the Cd and As treated soil was shown that exchangeable, dilute acid extractable, and organically bound form, which were more mobile and phyto-available, of Cd were increased by 5.6, 42.9, and 56.7% during a growing season whereas 17.6, 25.0, and 24.1% were increased in case of As, respectively. Specially, the Cd content of leaves and roots in lettuce was positively correlated with exchangeable, dilute acid extractable, and residual form of Cd in the treated soil. However, the As content of roots in lettuce was positively correlated with all chemical forms of As in the treated soil. The contents of putrescine and cadaverine, a kind of polyamine, were also increased in lettuce as both elements were increased in soil.

  • Elevated plasma homocysteine (Hcy) is a risk factor for cognitive dysfunction and Alzheimer disease, although the mechanism is still unknown. Both folate and betaine, a choline metabolite, play essential roles in the remethylation of Hcy to methionine. Choline deficiency may be associated with low folate status and high plasma Hcy. Alterations in DNA methylation also have established critical roles for methylation in development of the nervous system. This study was undertaken to assess the effect of choline and folate deficiency on Hcy metabolism and genomic DNA methylation status of the liver and brain. Groups of adult male Sprague Dawley rats were fed on a control, choline-deficient (CD), folate-deficient (FD) or choline/folate-deficient (CFD) diets for 8 weeks. FD resulted in a significantly lower hepatic folate (23%) (p<0.001) and brain folate (69%) (p<0.05) compared to the control group. However, plasma and brain folate remained unaltered by CD and hepatic folate reduced to 85% of the control by CD (p<0.05). Plasma Hcy was significantly increased by FD $(18.34{\pm}1.62{\mu}M)$ and CFD $(19.35{\pm}3.62{\mu}M)$ compared to the control $(6.29{\pm}0.60{\mu}M)$ (p<0.001), but remained unaltered by CD. FD depressed S-adenosylmethionine (SAM) by 59% (p<0.001) and elevated S-adenosylhomocysteine (SAM) by 47% in liver compared to the control group (p<0.001). In contrast, brain SAM levels remained unaltered in CD, FD and CFD rats. Genomic DNA methylation status was reduced by FD in liver (p<0.05) Genomic DNA hypomethylation was also observed in brain by CD, FD and CFD although it was not significantly different from the control group. Genomic DNA methylation status was correlated with folate stores in liver (r=-0.397, p<0.05) and brain (r = -0.390, p<0.05), respectively. In conclusion, our data demonsoated that genomic DNA methylation and SAM level were reduced by folate deficiency in liver, but not in brain, and correlated with folate concentration in the tissue. The fact that folate deficiency had differential effects on SAM, SAH and genomic DNA methylation in liver and brain suggests that the Hcy metabolism and DNA methylation are regulated in tissue-specific ways.

  • Peripheral bood stem cell collection (PBSCC), including peripheral blood stem cell transplantation (PBSCT), has been utilized worldwide as a very beneficial treatment method instead of allogenic Bone Marrow Transplantation (BMT) because it has many advantages such as rapid bone marrow engraftment and hematopoietic recovery, easy and safe accessibility and lower risk of rejection compared with allogenic BMT. In order to identify most the observable parameter in PBSCC, we analyzed various hematological parameters before and after PBSCC, and evaluated the correlation between the time of bone marrow engraftment and the number of CD34+ cells. Thirteen patients, who underwent 54 PBSCCs from January, 2003 to August, 2004 at Chungnam National University Hospital due to various systemic neoplasms, were analyzed in aspects of various hematological parameters including CD34+ cells using by Flow Cytometry (FCM). PBSCC harvests are described below: Mononuclear cells (MNC) $2.3{\pm}1.4{\times}10^8/kg$ and CD34+ cells $0.63{\pm}0.35{\times}10^6/kg$ on average, respectively. There was a statistical significance in Hb and Hct before and after PBSCC, but not in WBC and platelet counts. The period to reach the hematological bone marrow engraftment was 13.4(10~21) days and 19.5(11~38) days according to the criteria of absolute neutrophile counts (ANC) ${\geq}500/uL$ and platelet counts ${\geq}50,000/{\mu}L$ in peripheral blood, respectively. There was a significant correlation between the numbers of CD34+ cell and ANC (p<0.05), and a borderline significance between MNC and ANC (p=0.051). We found that a group of patients, who were infused with CD34+ cells more than $3.5{\times}10^6/kg$, reached more rapidly the period of bone marrow engraftment in platelet counts (p=0.040). This present study suggested that Hb and Hct were the most useful parameters and should be closely monitored before and after PBSCC, that a PBSCT with the dosage of more than $3.5{\times}10^6/kg$ of CD34+ cells was needed to perform successful bone marrow engraftment, and additionally that platelet counts could be more useful in indicating bone marrow engraftment than ANC.

  • 1. Objectives To compare the contents of heavy metals, residual pesticides and sulfur dioxide before/after decoction. 2. Methods The heavy metal contents before/after decoction were measured by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) and mercury analyzer. In order to analyze pesticides in 3 samples we used simultaneous multi-residue analysis of pesticides by GC/ECD, followed by GC/MSD analysis to confirm the identity of the detected pesticide in each sample. In addition, the contents of sulfur dioxide (SO2) were performed by Monier-Williams distillation method. 3. Results 1) The mean values of heavy metal contents (mg/kg) for the samples were as follows: Yuldahanso-tang (before decoction - Pb; 1.85, Cd; 0.148, As; 0.042 and Hg; 0.003, after decoction - Pb; 0.096, Cd; 0.006, As; 0.006 and Hg; 0.002), Chongsimyonja-tang (before decoction - Pb; 1.193, Cd; 0.094, As; 0.084 and Hg; 0.008, after decoction - Pb; 0.053, Cd; 0.007, As; 0.011 and Hg; not detected) and Taeyeumjowee-tang (before decoction - Pb; 0.878, Cd; 0.078, As; 0.302 and Hg; 0.004, after decoction - Pb; 0.079, Cd; 0.005, As; 0.006 and Hg; not dectcted). 2) Contents (mg/kg) of residual pesticides before/after decoction in all samples were not detected. 3) Contents (mg/kg) of sulfur dioxide (SO2) before decoction in Yuldahanso-tang, Chongsimyonja-tang and Taeyeumjowee-tang exhibited 6.1, 37.8, 31.5 and 19.7, respectively. However, contents of sulfur dioxide after decoction in all samples were not detected. 4. Conclusion These results will be used to establish a criterion of heavy metals, residual pesticides and sulfur dioxide.

  • To evaluate the therapeutic effects of BGG on atopic dermatitis, we investigated the composition of immune cells of lymph node, PBMC and skin of Dermatophagoides farinae-induced NC/Nga mice. The levels of immunoglobulins in serum were analyzed at the protein level and the amount of pathologic cytokines were investigated using CD3/CD28 stimulated splenocytes. The results are summarized below; 1. BGG showed no cytotoxic effect up to $200\;{\mu}g/m{\ell}$ on mLFC in vitro. 2. BGG showed no hepatotoxicity in vivo based on the levels of ALT and AST. 3. Atopic dermatitis was improved through naked eye examination. BGG reduced the skin clinical index from 2.9 to 1.3 (p<0.01). 4. H&E and toluidine blue staining of tissue biopsies revealed that BGG inhibited the infiltration of lymphocytes and mast cells to skin. 5. BGG reduced the number of CD19 positive B cells in PBMCs by 16% (p<0.01), whereas cells were increased by 26% (p<0.05) in lymph nodes. 6. BGG reduced the numbers of B220+/CD23+ cells by 15% (p<0.01) and 33% in PBMCs and lymph node, respectively. 7. BGG reduced the numbers of B220+/IgE+ cells in PBMCs and lymph node by 21% and 33% (p<0.01), respectively. 8. BGG suppressed the levels of IgE (13%, p<0.001) as well as IgM (34%, p<0.001), IgG2a (40%, p<0.001) and IgG2b (26%, p<0.05). 9. BGG reduced the levels of IL-4 and IFN-$\gamma$ by 7% (p<0.05) and 13% (p<0.001) in anti-CD3 and anti-CD28-activated splenocytes, respectively. 10. BGG considerably inhibited the production of TNF-$\alpha$ and IL-6 by 42% (p<0.01) and 15% in the serum, respectively. Based on the results above, we concluded that BGG has therapeutic effects on atopic dermatitis by regulating the differentiation of B cells and isotype switching of IgE. Further investigations on the molecular mechanisms of BGG on atopic dermatitis are anticipated.

  • In odor to select optimum extraction methods of volatile compounds in beef extract powder(BEP) as basic data for the development of a new detection method of irradiated BEP, four extraction methods, such as solid phase microextraction with polar fiber(S-PD) and non-polar fiber(S-CD), purge and trap(P&T) and liquid liquid continuous extraction(LLCE) methods, were tested with gas chromatography/mass spectrometry method. A total of 106 volatile compounds including 22 hydrocarbons, 7 aldehydes, 6 ketones, 13 alcohols, 6 sulfur-containing compounds, 19 nitrogen-containing compounds, 6 aromatic compounds, 17 terpenes, 8 furans and 2 miscellaneous compounds were detected in BEP by four detection methods. The most compounds(62 compounds) were detected by S-PD method, followed by P&T(43), LLCE(38) and S-CD method(30). Among these methods, S-PD and P&T methods showed a complementary interrelationship to detect volatile compounds as S-PD method showed high detectabiltiy to all compound groups except hydrocarbons and ketones, which had high volatility and low molecular weight(less than RI 1200), but P&T method showed the contrary pattern to that of S-PD method. Moreover, the most of volatile compounds detected by S-CD and LLCE methods were also detectable by S-PD or/and P&T methods. Therefore, the simultaneous application of S-PD and P&T methods were selected as the optimum volatile extraction methods of BEP.
