High tidal volume ventilation is detrimental to alveolar fluid clearance (AFC), but effects of ventilation pressure (P) on AFC are unknown. In anesthetized BALB/c mice ventilated at constant tidal volume (8 ml/kg), mean AFC rate was 12.8% at 6 cmH(2)O P, but increased to 37.3% at 18 cmH(2)O P. AFC rate declined at 22 cmH(2)O P, which also induced lung damage. Increased AFC at 18 cmH(2)O P did n...
OBJECTIVE To compare the effectiveness and associated costs of carbonic anhydrase inhibitors + beta-blocker versus alpha-2 adrenergic agonists + beta-blocker in glaucoma therapy, as documented by The United Kingdom General Practitioner Research Database (UK-GPRD). RESEARCH DESIGN Patient chart analysis. METHODS Patient records were screened for diagnoses of ocular hypertension or glaucoma, ...
Mechanisms of beta-receptor stimulation-induced improvement of acute lung injury and pulmonary edema
Acute lung injury (ALI) and the acute respiratory distress syndrome are complex syndromes because both inflammatory and coagulation cascades cause lung injury. Transport of salt and water, repair and remodeling of the lung, apoptosis, and necrosis are additional important mechanisms of injury. Alveolar edema is cleared by active transport of salt and water from the alveoli into the lung interst...
BACKGROUND Controversy remains regarding the effectiveness of bronchodilators in wheezy infants. AIMS To assess the effect of inhaled beta(2) agonists on lung function in infants with malacia or recurrent wheeze, and to determine whether a negative effect of beta(2) agonists on forced expiratory flow (V'(maxFRC)) is more pronounced in infants with airway malacia, compared to infants with whee...
Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis in infants and children worldwide. We wished to determine whether intratracheal administration of beta-agonists improved alveolar fluid clearance (AFC) across the distal respiratory epithelium of RSV-infected mice. Following intranasal infection with RSV strain A2, AFC was measured in anesthetized, ventilated BALB/c mic...
