[Functional diagnostics of the adrenal cortex following long term treatment with prednisolone].

Promounced cases of disturbances of the function of the adrenal cortex may more certainly be found out with the help of the enlarged sinacthen test than after a stimulation done only but once. In a long-term prednisolone therapy of 10 mg/a day we could observe signs of disturbances of the function of the adrenal cortex. A clear evidence in the estimation of the individual value is possible only in decreased plasmacortisol levels which are during the whole course of the experiment. When a prednisolone therapy is established for a longer time apart from the sequels at the adrenal cortex should be thought also of the great number of the side effects caused by the catabolic properties of the cortico-steroids.

Effect of chlorphentermine on hormone content and function of the adrenal cortex in rats.

Amphiphilic drugs like chlorphentermine induce a generalized lipid storage disease upon chronic application. The adrenal cortex is among the organs most heavily affected. We therefore determined the urinary corticosterone excretion during the treatment of rats with chlorphentermine and the corticosterone content of the adrenals and its blood level at the end of the treatment period. In addition, the responsiveness of adrenal cortex was tested by application of ACTH. During treatment, the corticosterone excretion declined considerably. Both the corticosterone content of the adrenals and the plasma level were found depressed at the end of a treatment period of 8 weeks. The ACTH evoked response was also diminished. The results indicate that the chlorphentermine-induced lipidosis is associated with a reduced corticosterone production of the adrenal cortex of rats. At present it cannot be decided whether the cortical insufficiency is causally related to lipidotic alterations of the cortical cells, or whether it is caused or additionally influenced by alteration at a higher level, e.g. hypothalamic centers or anterior pituitary.

About the relationship between adrenal cortex and thyroid gland of rats (shift-effect).

In the present paper the inverse quantitative relationships between the thyrotropical system and the adrenocorticotropical system should be demonstrated under different acute experimental conditions by caryometric investigations. In stimulating the adrenal cortex system by a single injection of 0.2 ml saline solution (0.9%)/rat the nuclear sizes of the thyroid follicular cells decreased timedependend whereas the nuclear parameters of adrenal cortex fasciculata cells increased. In inhibiting the adrenal cortex system and stimulating the thyrotropical system by a single injection of 50 micrograms TRH/rat the thyroid nuclear values increased timedependend biphasically and the adrenal cortex parameters decreased correspondingly. The inverse relationships of the histometric parameters of both endocrine organs proved to be highly significant (p less than or equal to 0.001). The mathematical relations could be expressed by the straight line y = 63.76 - 1.05 x.
