We measured the concentration of endogenous digitalis-like factors (EDLFs) in milk or colostrum of women during nursing on different days after delivery. EDLF concentrations were assayed by a solid-phase RIA involving antidigoxin antibodies and by a radioreceptor assay (RRA) involving human placenta Na+/K(+)-ATPase. The mean (SD) EDLF concentrations as(More)
BACKGROUND Helicobacter pylori has attracted increasing attention among gastroenterologists because of its pathogenic potential, stimulating the search for non-invasive diagnostic tests. AIMS In this study the efficacy of a new enzyme immunoassay designed to detect H. pylori antigens in stools (HpSA) was evaluated before and after eradication therapy. (More)
After having characterized epidemiologically, etiopathogenetically diagnostically, prognostically and psychologically the childhood headache, the A.A. refer data relative to 94 children of age in between 6 and 16 years, of which 51 females and 43 males, suffering for migraine (diagnosed by Bille's criteria). The ratio between migraine and sex, age,(More)
The lungs are a site for the uptake, accumulation, and storage of exogenous basic amines. The compound N-N-N'-trimethyl-N'-(2-hydroxy-3-methyl-5-iodobenzyl)-1,3 propanediamine (HIPDM) is a basic amine that can be labelled with radioactive iodine and detected by external counting. Intravenously injected 123I-HIPDM is extracted by the human lung, where it is(More)
In an attempt to confirm the presence of endogenous substances with cardiac glycoside-like activity, the biological and immunological cardiac glycoside-like activity was measured by a sensitive solid-phase radioimmunological assay (RIA), two radioreceptor assays (RRA), and a 86Rb uptake method in normal subjects and in some pathophysiological conditions(More)
The aim of our study was to evaluate whether adrenals are involved in the secretion of endogenous digitalis-like factor(s) with polarity similar to (or less than) that of ouabain (EDLF-1), and whether acute plasma volume expansion is a physiological releasing stimulus for this factor(s) in humans. For this purpose, we measured the concentration of this(More)
Recent studies have provided evidence that hypoxia may stimulate the release of endogenous digitalislike factors (EDLF). Obstructive sleep apnea (OSA) is characterized by intermittent hypoxia during sleep and may be associated with sympathetic activation and a high risk of developing hypertension. This study was designed to measure EDLF in the plasma of(More)
