to ascertain if the age-related reduction in the concentration of alpha-mshi may be a result of a decline in the production of pro-opiocortin , we determined the content of immunoreactive acth ( acthi ) , alpha-msh ( alpha-mshi ) , gamma-lph ( gamma-lphi ) , and protein , in 3 regions of the brain of young ( 4 months ) and old ( 26-28 months ) female rats : the medial basal hypothalamus ( mbh , the region containing the perikarya of the acth/msh/lph neurons ) , the preoptic anterior hypothalamus ( poa ) , and the thalamus ( regions containing axons of these neurons ) .
