Transverse CAT of the myocardium with 201 T1.

A new computerized axial tomographic (CAT) scanner (J&P Tomoscanner) which enables the transverse section viewing of any organ labelled by one of the monophotonic gamma-ray emitting racers commonly used in Nuclear Medicine, has been recently commercialized. Its abilities in visualising the 201 T1 labelled myocardium are evaluated with normal hearts and patients with documented infarctions. Positive results have been obtained, allowing an interesting approach to the estimation of the anatomical extent of necrosis.

[In vitro biosynthesis of iodothyronines from diiodo-3,5-L-tyrosyl-diiodo-3,5-L-tyrosine (author's transl)].

A comparative study of two types of in vitro synthesis of iodothyronines has been done from 3,5-diiodotyrosine and from diiodo-3,5-L-tyrosyl-diiodo-3,5-L-tyrosine (Tyr(I)2-Tyr(I)2) (equimolecular in tyrosyl rings). Incubations are made with rat thyroid gland minces in Eagle's medium or with thyroid microsomal fraction. Synthesis of thyroid hormones from Tyr(I)2-Tyr(I)2 is faster and more important than from diiodo-3,5-L-tyrosine (Tyr(I)2). A mechanism of iodothyronine formation via Tyr(I)2-Tyr(I)2 and different from the one occuring for Tyr(I)2 is suggested.
