In vitro leptin treatment of rainbow trout hypothalamus and hindbrain affects glucosensing and gene expression of neuropeptides involved in food intake regulation.

abstract：:Ethanol (ETOH) has been shown to have pronounced effects on reproductive endocrinology in humans as well as laboratory animals. We have studied the effects of ETOH on the hypothalamic-pituitary-luteinizing hormone (LH) axis, using the male rat as an animal model. In order to better understand the method by which ETOH ...
