Two Insulin Studies -- Part I: Circadian Cycles of Insulin in Normal and Diabetic Man / Part II: The Role of Insulin in Lipogenesis in Chick Embryo Heart

Abstract

In the first study, the research was concerned with the study of the circadian cycle of insulin secretion in normal and diabetic man, with and without chloropropamide treatment. It was designed to investigate insulin release after food intake and the possible correlation to other circadian cycles. As background for the second study, it has been demonstrated that the chick embryo heart is an excellent tool for insulin study. It was shown that the permeability of the chick embryo heart changes during ontogeny and that an insulin transport system developed on the seventh day of incubation.
