13. Stereological study of vasa vasorum in coronary arteries with different degrees of atherosclerosis / Estudo estereológico dos vasa vasorum em artérias coronárias com diferentes graus de aterosclerose
Introdução: Cerca de 50% dos casos de doença arterial coronária aterosclerótica (15% das mortes masculinas e 25% femininas) não são explicados pelos clássicos fatores de risco. Vasa vasorum coronários podem associar-se à aterosclerose coronariana; contudo, sua anatomia e fisiopatologia não estão completamente elucidadas. Objetivos: Realizar estud

14. Measurement of the ultrasonic properties of human coronary arteries in vitro with a 50-MHz acoustic microscope
Ultrasonic attenuation coefficient, wave propagation speed and integrated backscatter coefficient (IBC) of human coronary arteries were measured in vitro over the -6 dB frequency bandwidth (36 to 67 MHz) of a focused ultrasound transducer (50 MHz, focal distance 5.7 mm, f/number 1.7). Corrections were made for diffraction effects. Normal and diseased coronar

15. Comparison between Adventitial and Intimal Inflammation of Ruptured and Nonruptured Atherosclerotic Plaques in Human Coronary Arteries
OBJECTIVE: To verify the possible role of adventitial inflammation in atherosclerotic plaque vulnerability and coronary artery remodelling. METHODS: We compared the mean numbers of lymphocytes in the adventitia and in the plaque of ruptured thrombosed and stable equi-stenotic coronary segments of 34 patients who died due to acute myocardial infarction. We al

16. Alterações semelhantes a displasia fibromuscular (ADSFM) em vasos mesentericos : um fenomeno de remodelamento?
The study of vascular diseases is of growing importance, since cardiovascular diseases are one of the most important causes of death. Arterial remodelling is a non-specific phenomenon due to various different pathological processes. The aim ofthis study was to investigate adventitial fibromuscular dysplasia-like lesions (FMDLL) in mesenteric arteries and to

17. Great amount of C.pneumoniae in ruptured plaque vessel segments at autopsy. A comparative study with stable plaques
A possible relationship between C.pneumoniae (CP) infection, atherosclerosis and acute myocardial infarction is a debated matter. Now we performed the search of CP in histological segments of fatal ruptured plaques and of stable plaques by histochemistry (Macchiavello stain), immunohistochemistry and in situ hybridization techniques. Electron microscopy and

18. Localization of a constitutively active, phagocyte-like NADPH oxidase in rabbit aortic adventitia: Enhancement by angiotensin II
Superoxide anion (O2−) plays a key role in the endogenous suppression of endothelium-derived nitric oxide (NO) bioactivity and has been implicated in the development of hypertension. In previous studies, we found that O2− is produced predominantly in the adventitia of isolated rabbit aorta and acts as a barrier to NO. In the present studies, we character
