Abstract We have used intratracheal instillation of bleomycin in rats to study the microanatomical changes blood vessels associated with lung fibrosis. Bleomycin is a toxic cytostatic drug employed classical models Wistar were submitted injection 1.5 units and sacrificed 2.5 months later, timing when marked fibrosis observed. casted vascular tree rat lungs by perfusion methacrylate resin. These caste studied scanning electron microscopy. Lung tissue was also light microscopy thin section The...
Background Increased sympathetic activity has been implicated in hypertension. Adenosine shown to play a role blood flow regulation. In the present study, endogenous adenosine neuromodulatory role, mesenteric arteries from normotensive and spontaneously hypertensive rats, was investigated. Methods Results The of neurotransmission studied using electrically-evoked [3H]-noradrenaline release experiments. Purine content determined by HPLC with fluorescence detection. Localization A1 or A2A...
Abstract Adenosine plays an important role in the cardiovascular system, activating adenosine A 1 , 2A 2B and 3 receptors, regulating blood flow either by acting directly on vascular cells or indirectly because of its effects central peripheral nervous systems. The aim present study was to investigate whether pattern distribution receptor subtypes is different elastic muscular, using abdominal aorta tail arteries as models. Immunohistochemistry anti‐A antibodies performed...
We have investigated the topography of particle-laden macrophages in pulmonary tissue CD-I mice after intratracheal instillation a suspension 250 µg calcium tungstate. The were sacrificed 1,3,7 and 14 days particle deposition. Lung fragments studied by scanning electron microscopy (SEM) coupled with X-ray microanalysis that allowed situ elemental identification tungsten lungs. Tungsten-positive distinctly located lungs at 1-3 when compared samples from killed 7-14 tungstate instillation. At...
An ultrastructural study of the embryonic and larval shell Anodonta cygnea was carried out by light, polarization, scanning electron microscopy, X-ray diffraction analysis. A thin outer layer (cuticle), composed β-keratin fibrils organized in parallel rows enveloped chitin material, observed. The hooks, spines, teeth are constituted cuticular formations only. calcareous inner presenting convergent prismatic monocrystals mainly aragonite, which form structures around pores inside irregular...
Abstract This research have started with the idea to exploit possibility achieve some new materials in context of Nanotechnology Constructions, aid RTM–Resin Transfer Moulding process and inclusion nanofluids, considering possibilities orientation Nanomagnetic Fluids magnetic fields, as function desired properties for specified applications possessions. The future Nanomagnenetic presence mass composite materials, can be analyzed potential aeronautics or frequently used promote RTM process....
