The study aim was to evaluate urinary excretion of Retinol Binding Protein (RBP), compared with urinary excretion of N-acetyl-beta-D-glucosaminidase (NAG), in preterm infants with anoxia and netilmicin treatment. Urinary RBP and NAG were evaluated in 83 preterm newborns divided in 4 groups: 37
Urinary N-acetyl-beta-D-glucosaminidase activity was assayed in fullterm and preterm polycythemic neonates, in preterm infants with hypoxia, and in healthy newborns. There were no significant differences between fullterm and preterm babies or between appropriate for gestational age and small for
OBJECTIVE
To assess the time course of biochemical responses to neonatal anoxia.
METHODS
Neonatal anoxia was induced by placing 2-day-old rat pups into a glass chamber with 100% N(2) atmosphere, T=36.5 degrees C, for 20 minutes. The samples of serum, brain, lungs and liver were taken after 10
Effect of hypoxia on renal prostaglandin E2 (PGE2) production was shown in asphyxic newborn infants and experimental hypoxic rats. In asphyxic infants, at postnatal day 1, the urinary excretion of PGE2 in severe asphyxia (1.00 +/- 0.19 pg/kg/min, n = 10) was lower than that of the mild asphyxia
The authors investigated the urinary N-acetyl-beta-D-glucosaminidase (NAG) activity in the case of 101 normal healthy and 20 polycythemic newborns and prematures, and 50 prematures suffering from hypoxia on the 1st, 2nd, 4th, 14th, and 28th day after birth. The obtained activities were referred to
The isoenzyme forms of N-acetyl-beta-D-glucosaminidase (NAG) have been studied in the urine of patients with renal disease, those with stable and rejecting renal transplants, and after surgery. Besides the increase in total urinary NAG excretion as an indicator of renal damage, changes were shown in
A radioprotective effect of hypoxia was studied in kidney radiation. The use of hypoxic respiratory mixture containing 8% oxygen (the normal content is 21%) enhances kidney resistance to local single and fractionated irradiation. Determination of renal activity of succinate dehydrogenase, lactate
Urinary N-acetyl-beta-D-glucosaminidase (NAG) activity was assayed in 20 polycythemic newborns and prematures, together with 50 prematures suffering from hypoxia on the 1st, 2nd, 4th, 14th, and 28th day after birth. The enzyme was also assayed in 101 healthy newborns which provided normal reference
This study intended to analyze: (1) the effects of acute and severe hypoxia exposure on skeletal muscle oxidative stress and oxidative damage markers; (2) the protective role of the antioxidant glutathione against oxidative damage; and (3) the expression of heat shock protein 70 kDa (HSP70) induced
The kidney function can be assessed by a number of methods. The urinary excretion of enzymes, in particular N-acetyl-beta-D-glucosaminidase (NAG), is considered a relatively simple, cheap, fast and non-invasive method in the detection and follow-up of renal tubular function under various conditions.
BACKGROUND
Asthma is a chronic inflammatory disorder of the airways which results in chronic hypoxia. Chronic hypoxia and inflammation can affect renal tubular function.
OBJECTIVE
The aim of this study was to investigate renal tubular function and early kidney injury molecules such as urinary
BACKGROUND
Perioperative renal dysfunction following abdominal aortic aneurysm (AAA) repair is multifactorial and may involve hypotension, hypoxia and ischaemia-reperfusion injury. Studies of cardiac and hepatic transplant surgery have demonstrated beneficial effects on renal function of high-dose
The present pre- and postnatal study was carried out to investigate the effect of melatonin (MEL), a potent antioxidant, on biochemical variables in the in vivo model of intrauterine hypoxia in rats. Chronic hypoxia was induced pharmacologically by the administration of the anticonvulsant phenytoin
The cytoprotective effect of ulinastatin, a Kunitz-type protease inhibitor, was studied in L2 cells treated with antimycin A, which induces depletion of cellular adenosine triphosphate (ATP), so-called <hypoxia>>. Antimycin A treatment with 2 microM significantly elevated the release of
OBJECTIVE
Hypoxia occurs following convulsions, and hypoxia is one of the most common causes of acute renal damage. The aim of this study was to investigate urinary levels of kidney injury molecules, including neutrophil gelatinase-associated lipocalin (NGAL), N-acetyl-β-D-glucosaminidase (NAG), and
