Two hundred and twenty five patients of Takayasu's arteritis were studied over 13 years. Male:Female ratio was 1:7. Mean age of the study population was 19 +/- 4 years. Of these 225 patients, 75 patients had symptoms and/or signs of cardiac involvement and these patients were subjected to coronary angiography. Significant coronary artery occlusion (i.e. more than 50% narrowing of luminal diameter) was present in 9 patients. Incidence of coronary artery lesions in Takayasu's arteritis is 12% in this study. The proximal segments of coronary arteries were involved while the distal segments were spared. Out of 34 patients with angina pectoris, only 3 patients had significant coronary arterial narrowing. 相似文献

The expression and regulation of class II antigens in normal and inflammatory bowel disease peripheral blood monocytes and intestinal epithelium 总被引:2,自引:0,他引:2
Elevated constitutive expression of major histocompatibility (MHC) class II antigens occurs in the enterocytes of patients with IBD. It has been suggested that this aberrant expression of class II molecules may play a role in the pathogenesis of IBD. We examined two possible reasons for such a finding. 1) Heightened sensitivity of IBD enterocytes to endogenous gamma interferon (gamma IFN) and 2) enhanced endogenous secretion of gamma interferon by intestinal cells in close proximity to the enterocytes (lamina propria lymphocytes). Constitutive and gamma interferon stimulated HLA-DR and DP density on intestinal epithelial cells (IEC) and peripheral blood monocytes (PBM) from UC patients (IEC n = 13; PBM n = 20), CD patients (IEC n = 14; PBM n = 18) and non-IBD controls (IEC n = 12; PBM n = 20) were measured via flow cytometry (mean channel fluorescence). gamma IFN production by PHA stimulated and unstimulated lamina propria lymphocyte (LPL) cultures of UC patients (n = 11) CD patients (n = 8) and non-IBD controls (n = 11) was measured using a vesicular stomatitis virus/WISH cell bioassay. We found significantly greater gamma IFN secretion by IBD-derived PHA stimulated LPL than from non-IBD stimulated controls (CD = 39.4 +/- 12.4u; UC41.5 +/- 6.8u; NL = 22.4 +/- 8.3u, p less than 0.05) while gamma IFN induced HLA-DR and DP upregulation was no greater in IBD-derived IEC and PBM than in non-IBD controls.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

In recent years, the indications for permanent pacemakers have expanded. The interest has focussed on hypertrophic cardiomyopathy, dilated cardiomyopathy and a new entity called hypertensive hypertrophy with cavity obliteration (HHCO). Pacemaker therapy is establishing itself for the prevention of atrial fibrillation. Pacing for neurocardiogenic syncope with newer pacing mode has encouraging datas. Pacemaker for long QT syndrome, after cardiac transplant and for haemodynamic improvement in occasional cases of first degree atrio-ventricular block is getting attention. The AHA and ACC guidelines updated in 1998 for implantation of cardiac pacemakers, now include several of these newer indications. 相似文献
