Ultrastructural evaluation of eosinophilic leukocytes from a 2-yr-old asymptomatic girl with chronic benign neutropenia (CBN) revealed a variety of morphological abnormalities. All eosinophils obtained from blood and marrow specimens contained multipole microcrystalloids in most of the mature cytoplasmic granules. An increase in crystalloid-free, immature granules in late (bilobed nuclei) eosin...

OBJECTIVE To purpose an inflammatory risk score for aortic aneurysm endovascular treatment. METHODS Twenty-five patients were followed-up from preoperative period to third month postoperatively (1-hour, 6-hour, 24-hour, 48-hour, 7-day, 1-month, 2- month and 3month). Inflammatory variables were C-reactive protein, hemosedimentation velocity, interleukins (IL-6, IL-8), tumor necrosis factor-Alp...

OBJECTIVE To experimentally compare the structural and ultrastructural changes in isolated hypertrophied rabbits' hearts submitted to cardiac arrest protected using sanguineous and crystalloid cardioplegia solutions. METHOD The study comprised two experimental groups and one control group. In Experimental Group I, cardiac arrest was achieved by the continuous infusion of tepid sanguineous car...

BACKGROUND Hypertonic solutions are considered to have a greater ability to expand blood volume and thus elevate blood pressure and can be administered as a small volume infusion over a short time period. On the other hand, the use of hypertonic solutions for volume replacement may also have important disadvantages. OBJECTIVES To determine whether hypertonic crystalloid decreases mortality in...

Crystalloid-containing bodies that may be lysosomes were observed by electron microscopy in acinar and striated duct cells of normal fasted rat parotid glands. The crystalloids varied in number from animal to animal and from lobule to lobule. They consisted of either parallel linear densities with a 5Snm periodicity, or of alternating major dense and minor light lines, with a 15 nm distance bet...
