title: Antidiuretic hormone immunoactivity in tumour tissue from patients with bronchogenic carcinoma: with and without hyponatraemia.
abstract: Antidiuretic hormone (ADH) immunoactivity (28--164 pg/mg wet weight) was detected in the tumour tissue of only three out of thirty-two patients with carcinoma of the bronchus. All three patients had small oat-cell tumours and two had persistent hyponatraemia prior to death. Serum sodium was not obtained in the third patient. Serum sodium was normal in the remaining twenty-nine patients with undetectable ADH immunoactivity.
