Atrial Natriuretic Peptide in Patent Ductus Arteriosus

ABSTRACT: Plasma concentrations of atrial natriuretic peptide (ANP) were measured in nine infants (age 4 days- 9 months) before and after closure of patent ductus arteriosus. Initially all patients had marked ...

ANALYSIS OF PENTANE AND ETHANE: A POSSIBLE METHOD FOR QUANTITATION OF FREE OXYGEN RADICALS

It has been claimed that free radicals play a role in the pathogenests of a variety of diseases. This hypothesis has not been tested owing to methodological difficulties. Here we describe a simple, accurate me...

25 ETHANE AND PENTANE IN EXPIRED AIR. MEASUREMENT OF LIPID PEROXIDATION IN SMALL PRETERM INFANTS. 0111

Free oxygen radicals are claimed to be of major importance in tissue damage in the newborn. Ethane (E) and pentane (P) are specific products of free oxygen radical mediated lipid peroxidation (Lipids 12: 109-1...

Correlation of Patent Ductus Arteriosus Shunting with Plasma Atrial Natriuretic Factor Concentration in Preterm Infants with Respiratory Distress Syndrome

ABSTRACT: The concentration of plasma atrial natriuretic factor (ANF) and the mechanism for its secretion were investigated in 17 preterm infants with respiratory distress. Their mean gestational age was 29 wk...

92 ETHANE AND PENTANE AS POTENTIAL INDICATORS OF NECROTIZING ENTEROCOLITIS (NEC) IN VERY LOW BIRTH WEIGHT INFANTS (VLBI)

NEC was diagnosed in 4 VLBI (GA 28.5±1.7 wk; BW 777±134 g) at 2-6 d of age on the basis of clinical symptoms, laboratory and x-ray examinations, and was confirmed in laparotomy. 0-1 d before clinical diagnosis...

16 PENTANE AS INDICATOR OF INCREASED LPID PEROXIDATION IN BB RATS DURING DEVELOPMENT OF INSULIN DEPENDENT DIABETES

Free oxygen radicals (FOR) are hypothesized to take part in the destruction of the B-cell in type I diabetes (DM). As a volatile product of lipid peroxidation, we followed breath pentane (P)(Lipids 24: 157-9, ...

Generation of Free Radicals in Lipid Emulsion Used in Parenteral Nutrition

ABSTRACT: Lipid emulsions used in parenteral nutrition are prone to peroxidation that may be an important feature of oxygen-associated tissue damage. Incubation of lipid emulsion [Intralipid (IL)] with H₂O₂ and F...

PERSISTENT PULMONARY HYPERTENSION OF THE NEWBORN (PPHN) IS SELECTIVELY LOWERED BY PROSTACYCLIN (PC)

PPHN is a common indication for ECMO because of severe hypoxemia and mortality risk. We studied the effects of PC in 8 infants (b.wt.2540-4130 g, gest. age 34-42 wk) with respiratory failure and PPHN. At mean ...

Immaturity-Dependent Free Radical Activity in Premature Infants

ABSTRACT: To examine the role of immaturity in the free radical-mediated rate of lipid peroxidation in premature infants, we studied 27 infants [gestational age, 27.1 (SD 2.4) wk; birth weight, 970 (SD 330) g]...
