The authors used intracerebral microdialysis to harvest allantoin and parabanic acid, potential markers of in vivo oxygen radical activity, from the frontal lobe cortex of three patients in the neurointensive care unit after serious aneurysmal subarachnoid haemorrhage. Clinical events involving
Uric acid is an end-product of purine metabolism in Man, and has been suggested to act as an antioxidant in vivo. Products of attack upon uric acid by various oxidants were measured by high performance liquid chromatography. Hypochlorous acid rapidly
The crystal structure of parabanic acid (1H,3H-imidazoletrione, C3H2N2O3, Mr = 114.1) at 123 K [monoclinic, P2(1)/n, Z = 4, a = 10.704 (2), b = 8.187 (2), c = 4.969 (1) A, beta = 92.32 (1)o] has been determined by
Suitability of reverse-phase columns from different sources for separation of uric acid from its oxidation products.
