Estimation of oestrogen and progesterone receptors in chronic rhinitis.

The turbinates of 38 patients with chronic rhinitis were examined biochemically for oestrogen and progesterone receptors. Low levels of oestrogen-receptor-like activity (1-20 fmol/mg protein) were found in 50% of patients of both sexes. Progesterone receptor activity was also weak (1-16 fmol/mg protein) but was present only in 5 female patients. Immunocytochemical assay failed to demonstrate focal areas of oestrogen receptor activity. One juvenile nasopharyngeal angiofibroma was negative for both oestrogen and androgen receptors. Other possible mechanisms of hormonal action are considered.
