A simplified assay method of superoxide dismutase activity for clinical use
Abstract
A simple and inexpensive assay method of superoxide dismutase (SOD) activity of various biological materials has been developed. SOD activity can easily be measured by reading the medium's intense absorbance directly, and many samples can be treated in a short time using a reaction stopper which acts for a long time. Reproducibility of the assay method was excellent for the sample from an individual estimated at two different times (a week to a month) and the coefficient of variance was 5.1%. The mean and standard deviation of SOD activities of 45 blood samples from normal Japanese males 32.9 +/- 10.5 microgram per ml of blood; estimated using bovine SOD standard. The SOD activity of the fluid from lavaged lungs was 15.7 +/- 1.8 microgram/ml, and that of lung tissue homogenates from rats was 2.85 +/- 0.66 microgram/mg of protein.

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.
