A method for assessing arteriosclerosis comprising measuring the serotonin level in whole blood, serum or platelet-rich plasma and rating the serotonin level on such a scale that the lower it is, the more serious the arteriosclerosis is.

Method for assessing arteriosclerosis and diabetic nephropathy

A method of analyzing vitamin E components in a lipoprotein by subjecting a lipoprotein-containing sample to ion exchange chromatography to separate the lipoprotein, reacting the separated lipoprotein to a pretreating solution containing an organic solvent and a surfactant to liberate vitamin E components, and then subjecting the liberated vitamin E components to reverse phase chromatography. Also described is a method of judging various pathological conditions such as the pathological conditions of diabetes, the risks of coronary artery diseases, and the pathological conditions of myocardial infarction using levels of vitamin E components in the lipoprotein as an index.
