Free radicals have been implicated in the pathogenesis of neonatal sepsis and its complications. This study was conducted to determine the changes in the clinical status and the serum levels of lipid peroxidation products [malondialdehyde (MDA) and 4-hydroxylalkenals (4-HDA)] in 10 septic newborns treated with the antioxidant melatonin given within the(More)
Bis(2-ethylhexyl) phthalate (DEHP) is a compound widely used in plastics technology to impart flexibility to rigid polymers. We sought to determine whether the oral exposure of female rats to DEHP during gestation and suckling produces alterations in the litter. Female rats were exposed to different concentrations of DEHP suspended in drinking water (32.5(More)
Age is associated with an enhanced low density lipoprotein (LDL) oxidation and atherosclerosis, thus, subjects over 80 years without cardiovascular disease provide a model to investigate the protective factors against atherosclerosis. Serum paraoxonase (PON1), an high density lipoprotein (HDL)-bound enzyme, prevents LDL oxidation. The aim of the present(More)
BACKGROUND The treatment of acute cholecystitis in the elderly is still a subject of debate, particularly with reference to the timing of surgery and the role of laparoscopy. PATIENTS From January 1994 to June 2002 we observed 27 patients aged over 70 years with acute calcolous cholecystitis. The patients were submitted to ultrasonographic percutaneous(More)
In several models of essential hypertension in the rat, the pressor response to central cholinergic stimulation is enhanced with respect to age-matched normotensive controls. Neurochemical evidence is available from previous studies to suggest that both pre- (transmitter synthesis and release) and post-synaptic (muscarinic receptors) components of(More)
Reactive oxygen species play an important role in the pathogenesis of respiratory distress syndrome and its complications. This study was conducted to determine if treatment with the antioxidant melatonin would influence interleukin-6, interleukin-8, tumor necrosis factor alpha, and nitrite/nitrate levels in newborns with grade III or IV respiratory(More)
Several researches has focused the hypothesis that low blood lead levels could be associated with an increased risk of hypertension. To assess the relation between occupational lead exposure and elevated blood pressure a group of 27 workers, age range from 27 to 62 years, mean (SD) 36.52 (+/- 8.16) yr; length of employment mean (DS) 2.97 (+/- 1.67) yr, were(More)
The couvade syndrome can be considered to be the psychosomatic equivalent of primitive rituals of initiation into paternity. Various symptoms have been described in the husbands of pregnant women with an incidence from 11% to 65%. The most common of these are: variations in appetite, nausea, insomnia and weight gain. Seventy-three couples with the women in(More)
OBJECTIVE The assessment of sedation level in critically ill patient remains a challenge for the intensivists in order to avoid over- or under-sedation phenomena. Scoring systems commonly used still show some limitation; the introduction of Bispectral Index (an EEG parameter) could bring potential advantages in monitoring sedation. According to the reports,(More)
alpha-Amanitin is an amatoxin known to produce deleterious effects on the liver and the kidneys, when circulating in the blood. It is produced by a particular kind of mushroom called amanita phalloides. Therapeutic options employed to treat mushroom intoxication, such as haemodiaperfusion on activated charcoal, high dosages of penicillin G, oral charcoal,(More)
