[Relationship between avascular necrosis and lipid and purine metabolisms].

The serum levels of uric acid, triglycerides, cholesterol, and lipoproteins were determined in 35 patients suffering from primary avascular necrosis. The results were compared with those of a control group and with those of patients suffering from gout. The frequency distribution of the results in the three groups was of the log-normal type and statistical calculations were made on logarithmic transformations of the serum values.
