Résumé
Primary intestinal lymphangiectasia is a congenital lymphatic disorder characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen and responsible for protein losing enteropathy. As a result, generalized edema, hypoalbuminemia, and lymphocytopenia are clinically manifested. We could not find the reason by several examinations. Therefore, we performed double balloon enteroscopy (DBE), and intestnal lymphangiectasia was diagnosed histologically by a biopsy. DBE is a safe and effective method to diagnose small bowel lymphangiectasia. We report a case of primary intestinal lymphangiectasia, which occurred in a 54-year-old male patient with generalized edema and ascites.

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD), one of the components of Agent Orange, has been reported to be a deadly poison despite its presence at extremely small doses. TCDD is reported to cause various kinds of cancers and other harmful effects on humans. However, a correlation between exposure to TCDD and acute coronary syndrome (ACS) is not yet proven. Thus, we examined the correlation between exposure to TCDD and ACS through an analysis of coronary angiograms from veterans of the Vietnam War. Two hundred fifty-one consecutive men undergoing coronary angiograms owing to ACS between April 2004 and May 2009 at Gwangju Veterans Hospital were analyzed. Included subjects were between 50 and 70 years of age. The patients were divided into two groups: 121 patients who had been exposed to TCDD (Group I) and 130 patients who had not been exposed to TCDD (Group II). Clinical and coronary angiographic findings were evaluated. Baseline clinical characteristics, inflammatory markers, and echocardiographic parameters were not significantly different between the two groups. The incidence of hypertension (71.1% vs. 60.0%, p=0.039) and hyperlipidemia (27.3% vs. 16.9%, p=0.038) was higher in Group I than in Group II. Total occlusion, stent length, stent use, and coronary lesion characteristics were not significantly different between the two groups. The rate of major adverse cardiovascular events (MACE) had no relationship with exposure to TCDD. Exposure to TCDD might not affect severity or the rate of MACE in persons with ACS.

BACKGROUND: Cigarette smoking is an important modifiable cardiovascular risk factor, which is known to acutely increase arterial stiffness. But the chronic effects of smoking on arterial stiffness are still controvertial. We studied the effects of chronic cigarette smoking on arterial stiffness in Korean subjects. METHODS: Our subjects included those >18 years of age (n=2685, 991 females) who had undergone a pulse wave velocity from July 2004 to June 2008. They were classified into two groups, smokers (n=641) and non-smokers (n=2044). In addition to the pulse wave velocity (PWV), we reviewed the highly sensitive C-reactive protein levels in a random manner when it was available. RESULTS: Males were predominant in the smokers group. Smokers had significantly higher heart-femoral PWVs than non-smokers (1083.6+/-264.1 cm/sec vs. 1041.3+/-257.3 cm/sec; p<0.001). There was no linear relationship between smoking duration and PWV (r= -0.225, p=0.506) even after adjusting for age, sex, and body mass index. Furthermore, there was no difference in the ankle-brachial index between the two groups. On the multivariate regression analysis, age, male gender, hypertension, and diabetes were independent predictors of increased arterial stiffness. CONCLUSION: In this study, chronic cigarette smoking increased central arterial stiffness in Korean subjects.

BACKGROUND: Foot-and-mouth disease virus (FMDV) is a small single-stranded RNA virus which belongs to the family Picornaviridae, genus Apthovirus. It is a principal cause of FMD which is highly contagious in livestock. In a wild type virus infection, infected animals usually elicit antibodies against structural and non-structural protein of FMDV. A structural protein, VP1, is involved in neutralization of virus particle, and has both B and T cell epitopes. A RNA-dependent RNA polymerase, 3D, is highly conserved among other serotypes and strongly immunogenic, therefore, we selected VP1 and 3D as vaccine targets. METHODS: VP1 and 3D genes were codon-optimized to enhance protein expression level and cloned into mammalian expression vector. To produce recombinant protein, VP1 and 3D genes were also cloned into pET vector. The VP1 and 3D DNA or proteins were co-immunized into 5 weeks old BALB/C mice. RESULTS: Antigen-specific serum antibody (Ab) responses were detected by Ab ELISA. Cellular immune response against VP1 and 3D was confirmed by ELISpot assay. CONCLUSION: The results showed that all DNA- and protein-immunized groups induced cellular immune responses, suggesting that both DNA and recombinant protein vaccine administration efficiently induced Ag-specific humoral and cellular immune responses.
