title: [New enzymatic and endocrinological aspects in two cases of Werner's syndrome (author's transl)].
abstract: Results of endocrinological studies and of the investigation of intraerythrocytic glycolytic pathway carried out in two patients with Werner's syndrome are presented. An increase of glyceraldehyde 3-phosphate and 3-phospho-glycerokinase has been observed, but the significance of these original findings is still unknown. An hyperinsulinism after oral glucose overload has been demonstrated too. This finding, which has been reported by other authors, probably reflects a peripheral resistance to insulin action. Other endocrinological abnormalities were a decrease in the T3:T4 quotient and a slight delay in the FSH-LH peak to LH-RH.
