Adrenal depletion during hypoglycemia without participation of the Golgi apparatus.
Adrenal depletion in rats due to hypoglycemia was effected by prolonged administration of adrenaline, without artificial increase in insulin levels. In spite of significantly enhanced catecholamine turnover in this stadium Golgi complexes - which are usually reported to develop hypertrophy during adrenal depletion using insulin induced hypoglycaemia - could never be observed. This leads to the conclusions, that firstly the presence of hypertrophic Golgi complexes is not necessarily linked with increased catecholamine turnover and secondly that permanent adrenalin application suppresses and insulin application promotes the formation of Golgi systems. Moreover, our electromicrographs do strongly suggest, that catecholamine turnover is linked with the rough endoplasmatic reticulum.
