[Action of 5-hydroxytryptophan on serum thyreostimulin and prolactin in primary hypothyroidism (author's transl)].

Orally 5 HTP has significantly decreased serum TSH level in eight patients with primary non treated hypothyroidism, but not in five normal subjects. Serum T4 et T3 levels did not change and serum PRL did not increase in the two groups. These results indicate a possible inhibitory action of 5 HT on TSH regulation. Action of 5 HT on PRL has not been defined here.

[Hypoparathyroidism in adults (author's transl)].

The authors studied the clinical characteristics of primary and post-operative hypoparathyroidism in 39 patients. Laboratory follow-up data were compared under two different treatment programs using either AT 10 or 25 Hydroxycholecalciferol (25 OHCC). Clinical analysis revealed the atypical characteristics of primary hypoparathyroidism. From a therapeutic standpoint, AT 10 and 25 OHCC were equally effective in provoking a return to normal plasma calcium levels, except in complex cases of vitamin D resistance. 25 OHCC proved much easier to manipulate than at 10 and offered a higher security with respect tothe risk of hypercalcemia. The biological activity of 25 OHCC seems to differ from that of AT 10, especially regarding phosphorus metabolism.

[Abnormalities of insulin secretion in coronary patients. Apropos of 67 cases].

The curve of blood insulin levels recorded during the oral provoked hypoglycaemia test (OPHG) was studied in 67 proven coronary patients. None of the curves obtained was normal. The abnormalities found in this way are of two types: either a hypoinsulinaemic response, with a high non-retarded peak (type 1) or a high retarded peak (type 2), or else a hypoinsulinaemic response, with a flat curve (type 3) or a very small late peak (type 4). The possible role of these abnormalities of insulin secretion in the pathogenesis of atheroma is discussed. The correlations between age, sex, obesity, hypertriglyceridaemia, and the OPHG curve are investigated. The preliminary results of a test in which insulin levels are monitored after intravenous provoked hypoglycaemia, followed by tolbutamide, are reported.
