Increased Diene Conjugates in Diabetic Subjects with Microangiopathy
Abstract
Free radicals are highly reactive unstable chemical species which have been implicated in the vascular damage associated with several disease states. Diene conjugates, probable products of free radical activity on lipids, were measured spectrophotometrically in 26 diabetic patients with microangiopathy, 36 uncomplicated diabetic patients, and 36 healthy controls. Total diene conjugates and diene conjugate to triglyceride ratios were signficantly elevated in diabetic patients with microangiopathy (0.57±0.08 and 0.31±0.14 OD units/ml respectively; mean ±SD) when compared with patients without complications (0.32±0.10, p<0.001, and 0.17±0.06, OD units/ml, p<0.011). There was no difference in total diene conjugation and their ratio to triglycerides between healthy controls and uncomplicated diabetic patients and the results were not influenced by the type of diabetes or level of diabetic control. Diene conjugate ratios repeated in 14 patients on two occasions, 6 weeks apart, with stable metabolic control were consistent. Increased diene conjugation suggesting increased free radical activity is associated with microangiopathy and this may have pathogenetic implications.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
