title: Circadian variations of certain blood components currently investigated.
abstract: The circadian variations of serum components such as: cholesterol, LDH, GOT, alkaline phosphatase, proteins, bilirubin, ferrous ions and creatinine were investigated. Blood collection was made two times in 24 hrs.: 5-6 p.m. and 7-8 a.m. on the next day. The data obtained allowed the classification of the subjects into two groups: stable and variable. The most interesting observations were: evening decrease of cholesterol, evening increases of LDH with a tendency of intensification of the LDH5 fraction in the zymogram and evening decreases of ferrous ion.
