A group of sera from hospital patients and normal subjects has been tested for the presence
of antinuclear antibodies, and the amount of labile inhibitor to desoxyribonuclease 1 present
in each of the sera estimated. It has been found that the presence of antinuclear antibodies
is associated with a high level of inhibitor to a statistically significant degree. It has also been
found that this inhibitor is formed during the clotting of whole blood and that it is derived from
platelets. A possible relationship between the inhibitor, its formation during the clotting of …
A group of sera from hospital patients and normal subjects has been tested for the presence of antinuclear antibodies, and the amount of labile inhibitor to desoxyribonuclease 1 present in each of the sera estimated. It has been found that the presence of antinuclear antibodies is associated with a high level of inhibitor to a statistically significant degree. It has also been found that this inhibitor is formed during the clotting of whole blood and that it is derived from platelets. A possible relationship between the inhibitor, its formation during the clotting of blood, and the characteristic presence of antinuclear antibodies in systemic lupus erythematosus is discussed.
