ABSTRACT

Bone injury inflicted at varying time intervals during 24 hr day-night cycle caused significant varying increase in plasma 17-OHCS levels in all traumatized animals and the levels remained elevated up to 24 hr after trauma. The level of plasma 17-OHCS was found to be aberrated in all the traumatized animals. Thus, adequate adrenocortical response to trauma and aberration in the adrenocortical secretory activity appears inevitable irrespective of the time at which the trauma is produced. However, the degree of response depends on the particular time at which the trauma is inflicted.

ABSTRACT

Los resultados del tratamiento de la enfermedad de Cushing siguen siendo muy variables, lo cual indica que aún no se conoce su fisiopatogenia. La revisión de 12 casos en los que el diagnóstico se estableció mediante pruebas hormonales y tomografia craneal computada y se sometieron a microcirugía hipofisaria, reveló que el índice de curación fue bajo (42 por ciento) después del primer tratamiento y que el resto falleció (tres pacientes) o requirió de otro tratamiento. Se puede concluir que aunque en la actualidad no hay dificultad para establecer el diagnóstico, su tratamiento debe individualizarse. En caso de microadenoma el tratamiento de elección es operación transesfenoidal y, cuando se presenta persistencia, el siguiente recurso puede ser radioterapia ordinaria auxiliada por fármacos en forma temporal para disminuir los efectos del cortisol elevado en la sangre. En caso de macradenoma, que es índice de mal pronóstico, se debe hacer hipofisectomía y seguirse de radiación ordinaria. La adrenolectomía debe reservarse para los casos en que haya contraindicación absoluta para la operación hipofisaria

ABSTRACT

Dorsal septum is an intermediary centre in between the hippocampus and hypothalamus and it has got inhibitory influence over the hypothalamo-pituitary-adrenal axis. Stimulation of the dorsal septum manifested with fall in adrenocortical output whereas its lesion has opposite response. Ventral septum is a facilitatory area regarding activation of the hypothalamo-pituitary-adrenal axis. It is a balancing centre lying in between the higher central nervous system structures and the hypothalamus. Stimulation and lesion of the ventral septum led to rise and fall in adrenal venous 17-OHCS output respectively. Adrenocortical response to stress of burn was not blocked or inhibited following lesion of the dorsal as well as ventall septum.
