Pulmonary vascular sequestration of leukocytes has been reported to increase in some models of lung injury, including that induced by gram-negative bacterial lipopolysaccharide (LPS). Neutrophils recruited to the lung likely participate in LPS-induced lung inflammation and associated injury, but the functional activities of these pulmonary vascular(More)
Acute renal failure (ARF) is associated with erythropoietin (EPO) deficiency anemia. The present study was designed to determine whether the course of ARF can be altered by preventing EPO deficiency and the associated anemia. Sprague-Dawley rats were injected with a single dose of cisplatin (CP), 7 mg/kg intraperitoneally, and randomized into recombinant(More)
BACKGROUND The underlying mechanisms of elevated IgE level in atopic patients are still obscure, however, extensive efforts have been tried to identify an immunological parameter as a predictor of atopy. OBJECTIVE This study compared the difference in cytokine production by cord blood mononuclear cells between new borns with high-risk of allergy (family(More)
Effects of iron overload on intestinal function and structure are unknown and were, therefore, investigated. Sprague-Dawley rats were randomized into an iron-overloaded group, which received a single subcutaneous injection of 1.2 g/kg elemental iron-dextran complex, and placebo-treated pair-fed controls. Animals were studied after a 10-month observation(More)
Experiments were designed to determine the cause of the selective dysfunction of G(i) proteins, characterized by a reduced endothelium-dependent relaxation to serotonin (5-hydroxytryptamine), in coronary arteries lined with regenerated endothelial cells. Part of the endothelium of the left anterior descending coronary artery of female pigs was removed in(More)
Fifteen neuroendocrine carcinomas of the skin (Merkel cell tumors) were stained within the constraints of tissue availability by the Grimelius method and immunohistochemically for keratin, neuron-specific enolase (NSE), carcinoembryonic antigen (CEA), S-100, common leukocyte antigen (CLA), met-enkephalin, bombesin, calcitonin, ACTH, gastrin, and(More)
Three unusual cutaneous tumors are described along with ultrastructural and immunohistochemical studies. All lesions were asymptomatic red-brown papulonodules. Light microscopic examination revealed a whorled configuration of spindle-shaped cells, some concentrically arranged around blood vessels. Immunohistochemical panels exhibited positive staining only(More)
In the porcine coronary artery, regenerated endothelium is dysfunctional as regards the responses to endothelium-dependent agonists. The current study aimed to determine the possible involvement of histamine in such dysfunction. Pigs were treated chronically with pyrilamine (H1 receptor inhibitor, 2 mg·kg(-1)·day(-1)) with part of their coronary endothelium(More)
We studied the urinary concentrating capacity in experimental hemochromatosis. Sprague-Dawley rats were randomized into iron (Fe)-loaded (injected sc with 1.2 g elemental iron/kg body weight as iron dextran) and pair-fed control groups. The urinary concentrating ability was studied after 10 months of iron loading. At basal condition, urine osmolality (Uosm)(More)
