Olanzapine-Induced Neutropenia.

Olanzapine-induced neutropenia is a rare adverse effect that is currently poorly described in literature. Although neutropenia is a known adverse effect of clozapine, it has been associated with the use of other antipsychotic medications like olanzapine. This case report describes and reviews a case of olanzapine-induced neutropenia in a schizophrenic patient.

Gonadotropin-inhibitory hormone identification, cDNA cloning, and distribution in rhesus macaque brain.

Gonadotropin-inhibitory hormone (GnIH) is a hypothalamic neuropeptide that modulates the reproductive physiology of birds and mammals by inhibiting gonadotropin secretion from the anterior pituitary gland. GnIH can also directly inhibit reproductive behaviors, possibly via action within the brain. Identification of the distribution of GnIH neurons and fibers may provide us with clues to how the brain controls reproductive activities of the animal.
