A recent study in rats has demonstrated that plasma prolactin levels can be influenced by pineal activity (Relkin, Adachi & Kahan, 1972). In addition, increased plasma prolactin levels as well as increased aldosterone secretory rates are produced in rats by sodium deprivation (Relkin & Adachi, 1973). In an effort to ascertain whether sodium deprivation exerts its effect on plasma prolactin levels via the pineal the following experiment was performed.
Inbred male rats of the Wistar strain were pinealectomized according to the method of Hoffman & Reiter (1965), or sham-pinealectomized, at the age of 8 weeks (185 g), and housed singly in cages under conditions of 10 h light and 14 h darkness. One half of the pinealectomized and sham-pinealectomized animals were fed a sodium-deficient test diet (Hartroft & Eisenstein, 1957) containing 8 μequiv. sodium/g, and the remaining animals were fed a diet containing 108 μequiv. sodium/g. All animals were weighed
Journal of Endocrinology is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
