Pheochromocytomas are neuroendocrine tumors able to synthesise cathecholamines as well as to metabolise them in metanephrines (NM,M). We assayed Adrenaline, NorAdrenaline, Dopamine and metanephrines in serum (p) and urine (u), and the chromogranin A. We measured 11 parameters (Ap, Au, NAp, NAu, Du, MNp, MNu, Mp, Mp, 3Metu, CgA). Catecholamines and metanephrines were performed using HPLC with electrochemical detection, and CgA with an immunometric as...

The aim of our study was to evaluate the reference ranges of thyrotropin (TSH) and free thyroxin (FT4) assayed with 5 methods at the second and the third trimesters of pregnancy for women with iodine intake at the lower limit of the normal range. This study used 297 sera (42 controls without pregnancy with age <40 years, 139 women at the second trimester and 116 at the third with mean age to 27 years in both groups).
