Differences between prostaglandins I(2) and E(2) in their renal synthesis and pathophysiological roles were investigated in unilateral renovascular hypertension of different severities in 18 patients: 6 with mild stenosis (<75% of the diameter) of the renal artery, 7 with moderate stenosis (75% to 90%), and 5 with severe stenosis (>90%). Before and after aspirin administration (10 mg/kg), renal...

BACKGROUND Osteogenesis Imperfecta (OI) is characterized by a number of deviations in the orofacial region. The aims of the present study were to investigate the occurrence of temporomandibular disorders, to evaluate the psychosocial status, and to assess the dental occlusion in a population of adult OI patients. METHODS Participants (n = 75) were classified with mild OI, type I (n = 56), or ...

BACKGROUND Forced expiratory volume in 1 second (FEV1)/forced expiratory volume in 6 seconds (FEV6) has been proposed as an alternative to FEV1/forced vital capacity (FVC) for detecting airway obstruction. A fixed cut-off value for FEV1/FEV6 in a Korean population is lacking. We investigated a fixed cut-off for FEV1/FEV6 as a surrogate for FEV1/FVC for detecting airway obstruction. MATERIALS ...

objective(s): the aim of this study wasto investigate the effects of mild hypothermia therapy on oxidative stress injury of rabbit brain tissue after cardiopulmonary resuscitation (cpr). materials and methods: rabbit models of cardiac arrest were established. after the restoration of spontaneous circulation, 50 rabbits were randomly divided into normothermia and hypothermia groups. the followin...

STUDY OBJECTIVES To determine respective contributions of alveolar and proximal airway compartments in exhaled nitric oxide (NO) output (QNO) in pediatric patients with asthma and to correlate their variations with mild symptoms or bronchial obstruction. PATIENTS AND DESIGN In 15 asthmatic children with recent mild symptoms, 30 asymptomatic asthmatic children, and 15 healthy children, exhaled...
