[Radiocirculography in patients with cerebrovascular disorders].

The cerebral blood flow time (CBFT) was examined in 100 patients with brain circulatory disorders with the aid of radiocirculography (RCG). Use was made of 99mCc-pertechnetate (37 MBq) and a two-channel "Gamma" radiograph manufactured in the Hungarian Republic. The rate of film movement amounts to 160 mm/min at the time constant 10.

[Struma ovarii and strumal carcinoid].

Seven ovarian tumours (3 mature teratomas, 2 strumas with malignancy 2 strumal carcinoids) have been examined histologically, hystochemically and electron-microscopically. It is shown that the cell composition of the strumal teratoma tissue is very similar to that of the ectopic thyroid. The follicular cells may proliferate either into the benign tumour (apudoma) or typical thyroid carcinoma.
