Plasma Activity Levels in Radio-iodine Tests of Thyroid Function

Abstract

ABSENCE OF PULMONARY ARTERY BRiTiSH 493MEDICAL JOURNAL.displaced towards the affected side. The presence of a large pulmonary artery, which may even be aneurysmal, on the contralateral side and the absence of the shadow of a normal pulmonary artery at the hilum on the affected side are important signs. The latter feature may be difficult to appreciate on routine films, for the displaced heart may obscure the hilum. Penetrated films and tomograms of the hila are therefore of value. Bronchograms usually show a normal bronchial tree, as in the patient reported here, but in a few of the reported cases the affected lung has been small, in one case unilobar and in others agenetic. Confirmation of the absence of one of the pulmonary arteries can be obtained by angiocardiography.Summary A case of congenital absence of the left pulmonary artery occurring asymptomatically in a man of 30, associated with a right-sided aorta, is recorded. The literature is reviewed.

Autoimmune Phenomena in Pernicious Anaemia

“…of 1311; urinary excretion for the period of 6 to 24 hours after the dose; red-cell uptake of [13 I]tri-iodothyronine in vitro (Hamolsky et al, 1959); and plasma proteinbound radioactivity at 48 hours (Hughes and Miller, 1956). In some patients the thyroid uptake test was repeated 24 hours after intramuscular injection of 10 units of thyroid-stimulating hormone (T.S.H.…”

The Assessment of Thyroid Function: Prepared for the Association of Clinical Biochemists Scientific and Technical Committee

“…Normally the 48-h PB l a 1J is less than 0'4 % dose/litre of plasma but in thyroid overactivity it exceeds 0'7 %dose/litre (Hughes and Miller, 1956). The accelerated production of hormone by the thyroid in thyrotoxicosis can be distinguished from the much slower process in euthyroid individuals by measuring the plasma radioactivity 48 h after an oral dose of 5-50 p.Ci of 131 1 or 1251.…”
