[The effect of thyrostatic treatment on circulating thyrotropin-receptor antibodies in Basedow's disease]. / Vliianie na tireostatichnoto lechenie vurkhu tsirkulirashtite tireotropinretseptorni antitela pri bazedova bolest.

In 80 patients with Basedow's disease (20 nontreated and 60 under treatment with methimazole) were examined. The antibodies inhibiting the binding of TSH (TBII) by the radioreceptor method (Thyrotropin-Receptor-Anti-Körper Assay = TRAK), TRH-test, T3, T4, FT4, FT. TRAK-positive) values above 15 u/l) were 80% of the nontreated and 20% of the treated patients. In the course of 3 up to 6 months from the start of the treatment 60% of the examined patients were negative and at the end of the 18th month--92% were negative. A significant difference in the frequency of the recurrences was found between the TRAK-positive and the TRAK-negative patients. Between the TRAK, FT3, FT4, the size of the struma, the presence of ophthalmopathy [correction of ophthalmycthere] are positive relations. The following conclusions are made: 1. The determination of TBII and TRAK is not only of diagnostic but also of prognostic importance. 2. Methimazole exerts a specific immunosuppressive action and can lead to an immunologic remission in a comparatively short time.

[Dissociation between absorption of 131I-19-iodocholesterol and hormonal activity in corticosteroma patients]. / Disotsiatsiia mezhdu poglushchaneto na 131I-19-iodkholesterol i khormonalnata aktivnosti pri bolni s kortikosterom.

A case is described without clinical and hormonal data about Icenko-Cushing syndrome, with a scintigraphy of adrenals demonstrating the image, characteristic for corticosteroma (decompensated node). The most probable explanation of the finding is that the tumour is with restricted secretory possibilities and secrets mainly biologically inactive hormones, and furthermore it is not with an autonomous, but ACTH-dependent hormonal production.
