Releasing and inhibiting hormones Releasing and inhibiting hormones Releasing hormones and inhibiting hormones are hormones whose main purpose is to control the release of other hormones, either by stimulating or inhibiting their release. They are also called liberins () and statins () (respectively), or releasing factors and inhibiting factors. The examples are hypothalamic-pituitary hormones that can be classified from several viewpoints: they are hypothalamic hormones (originating in the hypothalamus), they are hypophysiotropic hormones (affecting the hypophysis, that is, the pituitary gland), and they are tropic hormones (having other endocrine glands as their target). For example, thyrotropin-releasing hormone (TRH) is released from the hypothalamus in
Pituitary pars intermedia dysfunction increased predisposition to infection usually take between 30 days and 1 year to improve. Cyproheptadine may be added to the treatment regime in horses that are inadequately responding to pergolide, but is usually only used in horses with advanced PPID on high doses of pergolide. Pituitary pars intermedia dysfunction Pituitary pars intermedia dysfunction (PPID), or equine Cushing's disease, is an endocrine disease affecting the pituitary gland of horses. It is most commonly seen in older animals, and is classically associated with the formation of a long, wavy coat (hirsutism) and chronic laminitis. Unlike the human and canine forms of Cushing's
