| Abstract: | Gravimetric and histologic modifications in the pigeon were studied following chronic therapy with ACTH and metopirone (SU 4885) for a period of 15 days. The organs studied were proventriculus, duodenum, heart, kidney, salivary gland, pancreas, liver, uropygial gland, thymus, spleen, bursa fabricii, testis, ovary, islets of Langerhans, adenohypophysis, thyroid and interrenal and chromaffin tissue of the adrenal gland. Induced states of hyper- and hypoadrenocorticalism elicited pathomorphic changes in endocrine and reproductive systems and some other organs of the pigeon. There were many differences and similarities in the nature of response of some organs following the two experimental conditions. Many of these cellular interactions might have resulted from alteration of interrenal function in the pigeon. |
