BACKGROUND The relative roles of endothelin (ET)-1 and angiotensin (ANG) II in post-ischaemic acute renal failure (ARF) have not been fully established so far. With the aim of contributing to this goal, we assessed in this study the effect of ANG II and ET-1 blockade on the course of post-ischaemic-ARF. METHODS Anaesthetized Wistar rats received i.v.(More)
BACKGROUND The pathophysiology of renal ischaemia, resulting in tubular cell injury and leading to acute renal failure (ARF), remains unclear. An ever-increasing number of investigations focus on a possible role of nitric oxide (NO) in regulating circulation during ARF. In this context, we investigated the influence of chronic stimulation or inhibition of(More)
BACKGROUND Inhibition of nitric oxide (NO) synthase by L-arginine analogs is associated with elevation of blood pressure in rats. Because endothelium-dependent vasomotion in different vascular beds is not homogenous, the aim of this study was to characterize and compare regional hemodynamic responses in carotid, femoral, and renal vascular beds after(More)
Helicobacter pylori infection is supposed to be one of the major causes of digestive and other diseases. Among a lot of invasive and non-invasive methods for its detection, none is ideal. The aim is an assessment of the Helicobacter pylori infection in the stomach using breath test and comparison to other diagnostic methods, as well as following up the(More)
Total proteinuria (SSA test) and beta-2-microglobulinuria (radial immunodiffusion and radioimmunoassay tests) were measured in 60 rural patients with histologically proven tumors of the renal pelvis and ureters and as many individually matched controls. The controls were the first neighbours of the same sex, age (+/- 2 yrs), profession and migratory(More)
The authors present a patient with delayed-type allergy against insulin preparations of different species including highly purified monocomponent insulin and human semisynthetic insulin. Positive results for cutaneous delayed-type hypersensitivity and for lymphocyte blastogenesis suggested a type IV immunopathogenic reaction. Intradermal tests performed(More)
A simplified and efficient procedure for 99mTc-HMPAO-labelling of leukocytes is described. For this purpose, the pH and concentration of the 99mTc-HMPAO preparation was modified. Leukocytes were isolated from a 20 mL mixture of patient blood, 5 mL ACD and 0.8 mL methylcellulose after 1 h sedimentation of erythrocytes and centrifugation (at 400 g) of the(More)
To study the pathological significance of circulating endothelin (ET) in ARF, we measured plasma ET in seven children (mean age 8.8 +/- 4.4 years) with ARF in the most severe phase and 3.7 +/- 3.5 months later in the recovery period. Twenty-seven healthy children were included in the study as controls. Plasma ET level was measured by highly sensitive and(More)
