Physiopathology of prolactin secretion in obesity.

In many species prolactin is of biological importance and has a major role in determining the deposition and mobilization of fat. In human physiology, outside pregnancy, prolactin secretion is altered by increasing body weight in both children and adults. Prolactin in this circumstance appears to be marker of hypothalamic-pituitary function: the prolactin response to insulin-hypoglycaemia, thyrotrophin releasing hormone stimulation and other stimulatory factors may be diminished.

Evidence for a difference in nitric oxide biosynthesis between healthy women and men.

There is indirect evidence for a gender difference in nitric oxide (NO) synthesis from vascular endothelium. The aim of the present study was to determine NO production more directly in healthy women and men by the measurement of 15N nitrate excreted in urine after the intravenous administration of L-[15N]2-guanidino arginine. Twenty-four healthy volunteers (13 men aged 22 to 40 years and 11 women aged 23 to 42 years) participated in this study.
