It's definitely a trend, and the handwriting is on the wall for anyone using chimpanzees in research. Public sentiment has also turned against using chimpanzees, especially in invasive studies, after decades of studies on the apes revealed their intelligent, emotional natures to be similar to our own.
Best Answer: CONCLUSION: Weight gain and elevated body weight are frequently associated with prolactinomas regardless of a mass effect on the hypothalamus or pituitary function. In this series, weight loss was recorded in 70% of prolactinomas patients and in 90% of male patients who normalized their prolactin levels. We propose the inclusion of hyperprolactinaemia in the differential diagnosis of endocrine obesity and weight gain.
Prolactin has a wide range of effects. It stimulates the mammary glands to produce milk (lactation): increased serum concentrations of prolactin during pregnancy cause enlargement of the mammary glands of the breasts and prepare for the production of milk.here is a diurnal as well as an ovulatory cycle in prolactin secretion. In many mammals, there is also a seasonal change in prolactin release. During pregnancy, high circulating concentrations of estrogen and progesterone increase prolactin levels by 10- to 20-fold.
