Abstract
In the 1 st section, a survey of methods for the conventional hormone laboratory was given in four lectures on the following topics: (1) determination of urinary estriol in pregnancy (B. Runnebaum, Heidelberg), (2) determination of urinary total estrogens in pregnancy (E. Kuss, Munich), (3) determination of estrogen fractions in non-pregnancy urine (W. Nocke, Marburg), (4) determination of total estrogen in non-pregnancy urines, using semi-automatic extraction (B. J. Smyth, Edinburgh). Following this section, conventional methods were thoroughly discussed. The 2nd section was dealing with methods for the highly specialised hormone laboratory. Five lectures on the following subjects were presented: (1) determination of the newly discovered estrogens (H. Breuer, Bonn), (2) separation of 81 different phenolic steroids by multiple paper chromatography (R. Knuppen, Bonn), (3) gas chromatography and mass spectrometry of estrogens (H. Adlercreutz, Helsinki), (4) estrogen methods using radio-active isotopes (J. H. H. Thijssen, Utrecht), (5) future developments in estrogen methodology (H. Breuer, Bonn). After this section, there was a panel on estrogen methodology followed by a general discussion. The symposium including the discussions will be published in full detail elsewhere.
