224 PURINES IN HYPOXEMIA/ISCHEMIA-REOXYGENATION IN PIGLETS

First report on infectious necrotic enteritis in piglets in Iran

Urinary purines in leukemia.

Urinary purine excretion has been determined for four normal subjects, for thirteen patients with different types of acute and chronic leukemia, and for one man with mycosis fungoides by means of paper chromatography. Differentiation between types of leukemia, based on punine excretion, was not conclusive. Increases in 1-methylhypoxanthine and 8-hydroxy-7-methylguanine in nearly all patients, a...

Methylated purines in urinary stones.

BACKGROUND The aim of the study was to measure the content of methylated purines that appear as admixtures in uric acid stones. METHODS We analyzed urinary calculi from 48 residents of Western Pomerania who underwent surgery at the urology ward in Szczecin. Stone samples were dissolved in 0.1 mol/L NaOH. Extracts were diluted in 50 mmol/L KH(2)PO(4) and analyzed by reversed-phase HPLC with ul...

Reoxygenation of Asphyxiated Newborn Piglets: Administration of 100% Oxygen Causes Significantly Higher Apoptosis in Cortical Neurons, as Compared to 21%

OBJECTIVE Evaluation of neuronal changes in an animal experimental model of normocapnic hypoxia- reoxygenation. MATERIALS AND METHODS Fifty male piglets were the study subjects; normocapnic hypoxia was induced in 40 piglets and ten were sham-operated (controls). When bradycardia and/or severe hypotension occurred, reoxygenation was initiated. Animals were allocated in 4 groups according to th...
