The organs, tissues, and cells of the lymphoreticular system have received considerable attention as targets for chemicals causing adverse effects. A basic toxicological approach is described for assessing the risk of a chemical perturbing the immune system. CD-1 mice were exposed for 14 or 90 days to one of several chlorinated hydrocarbons:(More)
Chloral hydrate has been found in our drinking water supplies at levels up to 5 micrograms/1. The purpose of this study was to evaluate the functional status of the immune system in random-bred CD-1 mice exposed to chloral hydrate for 14 and 90 days. Male mice, following 14 or 90 days of exposure to 1/10 and 1/100 the actual oral LD50, exhibited no(More)
Chloral hydrate has been found in our drinking water supplies at levels up to 5 micrograms/1. The purpose of this study was to evalute the acute and subchronic toxicology of chloral hydrate in the random-bred CD-1 mouse, to provide data for risk assessment. The acute oral LD50 of this compound was 1442 and 1265 mg/kg in male and female mice, respectively.(More)
Curvularia lunata has previously been linked to localized sinus infection in immunocompetent hosts. We treated a case of pansinusitis with extensive bone destruction and intracranial extension caused by C lunata. Curvularia lunata was identified when typical fungal macroconidia appeared on culture. Numerous surgical procedures, in addition to a 12-month(More)
Echocardiography is critical in the assessment of patients with hypoplastic left heart syndrome. Fundamental techniques and standardised approaches are useful when evaluating patients with hypoplastic left heart syndrome prenatally, after birth, and before the Norwood operation (Stage 1); after the Norwood operation, before and after the superior(More)
Manual ventilation of neonates suffering from respiratory distress is frequently performed in the hospital setting. The authors hypothesized that without manometer feedback present, experienced neonatal intensive care therapists cannot accurately estimate ventilating pressures. We also speculated that with rate feedback present, this same group could match(More)
