“…The rise in the concentration of a calcium in the blood which occurs both after adrenalectomy and after removal of the corpuscles-in contrast to the con¬ sequences of these operations in freshwater animals-may be due to alteration in the rate of absorption of calcium from the gut. This would mean that an adrenal hormone may influence transport across the intestinal epithelium (see Ussing, Kruli0ffer, Hess Thaysen & Thorn, 1960 ;Gaunt & Chart, 1962 ;Cofre & Crabbé, 1965). Cognisance must also be taken of the change in renal function.…”

The distribution of water, electrolyte composition (Na, K, Ca, Mg, PO4, Cl) and extracellular fluid volume of eels (Anguilla anguilla L.) were investigated under different experimental conditions. Adrenalectomy of the freshwater eel was followed by an increase in body weight, a fall in the amount and concentration of sodium in serum and muscle and a shift of water into the cells. The concentration of serum potassium remained within the normal range. Adrenalectomy of the sea-water eel was followed by a decrease in body weight and an increase in the concentration of extra-and intracellular sodium. The concentration of serum calcium also increased, that of potassium remained within the normal range but the actual content diminished.Removal of the corpuscles of Stannius from the freshwater eel gave some effects similar to adrenalectomy. There was, however, no significant increase in body weight but the concentrations of serum potassium and calcium rose. Removal of the corpuscles from the sea-water eel brought about changes similar to, but less pronounced than those after adrenalectomy. The results of the injection of mammalian corticotrophin, cortisol, aldosterone and anti-aldosterone compounds are given. They are discussed in the light of the possible roles of the adrenal cortex and the corpuscles of Stannius in the maintenance of homeostasis of the eel in different environments.

The relative weight of the Mongolian gerbil adrenal is one of the largest of any animal species. The adrenal cortex of the gerbil can be divided into three major zones and one zone located between the zona fasciculata and zona reticularis. Mitochondria1 cristae of zona glomerulosa cells are plate-like, those of the zona fasciculata are tubular whereas cristae are extensively developed and plate-like in the zona reticularis. Lipid droplets are numerous in fasciculata cells and sparse in glomerulosa and reticularis cells. Fasciculata and glomerulosa cells contain tubules of smooth endoplasmic reticulum whereas rough reticulum predominates in reticularis and border cells. Abundant lysosomes are found in glomerulosa cells; lysosomes are aggregated beneath the cell membrane of reticularis cells. Whorls of concentric lamellae of rough endoplasmic reticulum are localized exclusively to cells in the border zone. Cells in the border zone resemble those of the reticularis because of a virtual absence of smooth endoplasmic reticulum although mitochondria1 cristae are tubular and therefore similar to those of the zona fasciculata. It is suggested that cells in the border zone represent a reserve of cells which may transform into fasciculata cells upon stimulation.
