The number of children reporting rhinitis by month is compared with air pollutant concentrations in Lisbon, where they live and attend school. INAA, ionic exchange chromatography and data accessed through the internet were statistically processed wit

There is much controversy regarding the ability of sunscreens to prevent ultraviolet (UV)-induced immune suppression. Epidermal Langerhans cells (LC) play a key antigen-presenting role in the afferent limb of the immune system's response to antigens

Exposure to subcarcinogenic doses of ultraviolet (UV) radiation suppresses tumor immunity, thus permitting the emergence and growth of highly immunogenic skin cancers in mice. Sunscreens prevent UV carcinogenesis; however, there are conflicting repor

The effects of treatment with 0.2 mg/kg of indomethacin on the cerebral blood flow and cerebral oxygen consumption of hypotensive, unanesthetized, newborn pigs were investigated. Hypotension was induced by hemorrhage (30 ml/kg) which reduced mean art

We examined the effects of 20 minutes' cerebral ischemia on cerebral microcirculatory responses to topical norepinephrine and systemic hypotension in three groups (sham-operated control, 2-3 hours postischemia, and 24 hours postischemia) of anestheti

Vasopressin may be important in maintenance of arterial pressure and redistribution of cardiac output in hypotensive and asphyxiated newborns. We used chronically instrumented, unanesthetized, 4-day-old pigs to investigate the effects of hypotensive

Effects of ischemia (20 min) on cerebral cortical prostanoid synthesis and microvascular responses to hypercapnia and topical acetylcholine were examined in anesthetized newborn pigs. Pial arteriolar dilation in response to hypercapnia (10% CO2 venti

The effects of cerebral ischemia on cerebral microvascular reactivity and prostanoid synthesis were examined in chloralose-anesthetized newborn pigs. Microvascular responses and periarachnoid cerebrospinal fluid (CSF) prostanoid concentrations were d

The response of circulating catecholamines to asphyxia in unanesthetized, spontaneously breathing neonatal piglets was measured before and after treatment with indomethacin. Prior to treatment with indomethacin, baseline levels [geometric mean, pg/ml
