OBJECTIVE: To evaluate the modulation of the hypothalamus-pituitary-adrenal axis (HPA) on prolactin secretion in rats after adrenalectomy (ADX). MATERIALS AND METHODS: Plasma corticosterone, ACTH, and prolactin concentrations were measured by radioimmunoassay in rats after bilateral ADX in the short- (3 hours and 1day) and long-term (3, 7, and 14 days). RESULTS: Animals that underwent ADX showed undetectable corticosterone levels and a triphasic ACTH response with a transient increase (3h), a decrease (1d), and further increase in the long-term after ADX. Sham animals showed a marked increase in corticosterone and ACTH levels three hours after surgery, with a decrease to basal levels thereafter. Plasma prolactin levels were not changed after ADX. CONCLUSION: There are different points of equilibrium in the HPA axis after the glucocorticoid negative feedback is removed. Prolactin plasma secretion is not altered in the short or long- term after ADX, suggesting that the peptidergic neurons essential for prolactin release are not activated after ADX.

Topographical Relation

1. The thyroids of the adult Californian newt, Triturus torosus, were examined in Zenker, Champy, and Nassonov preparations, in one series in which these glands were entirely at rest, in another series in which they underwent a spontaneous activation and in a third group in which activation had been forced by intraperitoneal injections of thyroid activator. 2. As in invertebrates so in the newt the Golgi apparatus appears to consist of two components, of one which is deeply blackened, and of another one which stains much darker than the cytoplasm and corresponds to Bowen's idiosomatic substance. The former frequently forms a shell around the latter as a core. The problem has been discussed in the light of the work published recently by Owen and Bensley. 3. Only incomplete observations are available concerning a possible relation between Golgi apparatus and functional phase of the cell. (a) In the resting condition the Golgi apparatus is relatively small and compressed in an apico-basal direction. (b) In preparation for colloid release through the basal cellends, the Golgi apparatus enlarges greatly in an apico-basal direction and its trabeculae become stout. (c) In the cells in which fluid has accumulated in large lacunae and is excreted through the basal cell-ends, the Golgi apparatus begins to become fragmented into long, slender pieces. (d) In the cells in which basal excretion has ceased and the remaining liquid has been condensed into stainable droplets, the fragments are transformed into short, thick, and lumpy pieces. (e) When the colloid droplets are redissolved and transformed into vacuoles for the purpose of refilling the follicles, the Golgi bodies appear as black rings around a dark core. 4. In most instances the topographical relation existing between the Golgi apparatus and the secretion products is not specific. The distribution of the Golgi material represents merely an accurate repetition of the distribution of the cytoplasm. 5. In some instances, however, a close relationship is found between the Golgi apparatus and the secretion products (figs.12-15, 22, 23, PI. 36). 6. In no case does the Golgi apparatus show a reversal of its position from the apex to the base of the cell. In cells which are in an active state of basal excretion the Golgi apparatus may be strictly apical. Its position does not convey a knowledge of the excretion polarity of the cell.
