Abstract: | Discrete areas of freshly obtained adult bovine brain were assayed for their content of immunoreactive β-lipotropin (β-LPH), ACTH and β-endorphin. Highest concentrations (pg/100ug protein) of β-LPH were present in hypothalamus (517 ± 81), hippocampus (218 ± 60), central grey rostral mesencephalic level, pons, striatum, and spinal cord (163–258). Lesser concentrations (49–138) were present in other parts of the limbic system, brain stem, cortex and thalamus. Immunoreactive ACTH concentrations were highest in hypothalamus (1702 ± 487) and hippocampus (210 ± 40), with markedly lesser concentrations (5–24) being present in all the other aforementioned areas. Immunoreactive β-endorphin concentrations in hypothalamus were 1990 ± 510, in hippocampus 280 ± 50. |
