A new conventional simple and direct 125I-radioimmunoassay (RIA) for serum progesterone is described. In comparison with the classical tritiated assays which are preceded by extraction, the assay is more simple, less time-consuming, less subject to error and hence less expensive. In normal cycling females the serum progesterone range during the follicular(More)
A multicenter, randomized double-blind study of 6 months' duration was performed in 540 patients (average age 54 years, 57% male) with mild-to-moderate essential hypertension to determine the relative effects on quality of life of cilazapril, atenolol, and nifedipine retard. Quality of life was assessed by using both a self-administered and an(More)
