Tissue polypeptide antigen (TPA) in pleural effusions.

The usefulness of tumor marker assay in pleural effusions for differential diagnosis is still debated. From the observation of common antigens on tissue polypeptide antigen (TPA) and keratins 8, 18 and 19 and vimentin, all substances contained in normal and neoplastic mesothelium, we felt it opportune to evaluate the use of TPA assay in 105 pleural effusions (46 benign and 59 malignant). The values were much higher than those found in blood.

Longitudinal study of the behaviour of certain hormonal parameters in women undergoing treatment with cyproterone acetate.

A study has been made of the behaviour of certain hormonal parameters (LH, FSH, PRL, HGH, ACTH, cortisol and testosterone) in five women aged from 17 to 28 years, during two successive menstrual cycles, the first under basal conditions and the second while under treatment with cyproterone acetate (CPA) 100 mg/day), given from the fifth to the twenty-fifth day of the cycle. On the first day of the initial cycle and the twenty-ninth day of the second cycle, the secretion of gonadotropins, prolactin, and somatotropin were measured before and after stimulation with GnRH (50 microgram, i.v.
