Prenatal ethanol exposure reduces the density of the N-methyl-D-aspartate (NMDA) receptor agonist binding sites and decreases the capacity to elicit long-term potentiation (LTP) in hippocampal formation of 45-day-old rat offspring. We hypothesized that prenatal ethanol exposure would reduce metabotropic-glutamate receptor (mGluR)-activated phosphoinositide(More)
The effect of ethanol exposure during different periods of prenatal or postnatal development on hippocampal N-methyl-D-aspartate (NMDA) receptor binding was studied in rat. Fetal rat pups were exposed to ethanol for different periods of time during gestation via maternal consumption of a 3.35% ethanol liquid diet. In a separate experiment, neonatal pups(More)
PURPOSE The aim of this case series report is to assess the effectiveness of aspiration and injection of triamcinolone acetonide for treatment of wrist synovial cysts in children. METHODS Twenty-one records of pediatric patients with synovial cyst on the wrist treated with aspiration and triamcinolone acetonide injection were selected for analysis of(More)
BACKGROUND A symmetric case-crossover design was used to analyse the short-term relationship between air pollution, pollen and emergency calls to medical services. METHODS This study covered patients who made medical emergency calls in the City of Vigo (Spain) during the period 1996-1999. Morbidity data were obtained from the records of the 061 Medical(More)
A captive 10-year-old female northern pintail (Anas acuta) with a history of unilateral lameness was diagnosed at necropsy with polycystic disease most severely affecting the right kidney. The lameness was attributed to pressure on the sacral nerve plexus caused by the unusually large cyst arising from the right kidney. Polycystic kidney disease previously(More)
The release of tritium (3H) evoked by tyramine, potassium (K+) and 5-hydroxytryptamine (5-HT) from goat pial arteries preloaded with [3H]noradrenaline (3H-NA) was studied. In normal Krebs-bicarbonate solution (KBS) all these agents caused a transient increase in radioactivity release over the basal spontaneous outflow. The pattern of release evoked by 5-HT(More)
This study analyzes the changes induced by subarachnoid hemorrhage (SAH) on the contractile responses and the noradrenaline release evoked in cat cerebral arteries by histamine. The dose-dependent vasoconstriction induced by histamine on the cerebral arteries of normal cats was significantly reduced by diphenhydramine and phentolamine. When SAH was produced(More)
1. 5-Hydroxytryptamine (5-HT) induced dose-dependent contractions in the isolated cat femoral artery, which were reduced by LSD, methysergide, phentolamine and reserpine pretreatment (only at low doses). 2. Pentobarbital (PB) and Mn/+ relaxed the arteries previously contracted with 5-HT. These drugs reduced the contraction evoked by this amine as it was(More)
Previous studies of schoolchildren in Costa Rica have shown an asthma prevalence of 23% and a high level of sensitization, particularly to mite allergens. As a continuation of these studies, some 400 dust samples were collected from various places in Costa Rica, and parts of these were analyzed for specific mite and cockroach allergens, as well as for the(More)
