| pubmed-article:6254734 | pubmed:abstractText | A synthetic short chain ACTH, ACTH-1-17 (HOE 433 = Synchrodyn 1-17), beta-ala1, lys17 corticotropin (1-17)heptadecapeptide-4-N-butylamide, was tested for activity at the anticipated circadian stage of highest adrenal corticosterone responsiveness (22-HALO) in BALB/c mice. Statistically significant dose-response relations were demonstrated both in vitro (corticosterone production by adrenals incubated in Krebs-Ringer solution) and in vivo (increases in the serum corticosterone concentration). Leukocyte counts in mice injected with this ACTH showed statistically significant decreases (as compared to controls) for all kinds of cells except the neutrophil and medium-sized lymphocyte. | lld:pubmed |
