Daily, for 14 days, rabbits of one group were injected with corticotropin, i.e. ACTH-zinc-phosphate (10 units/kg), whereas rabbits of another group were given (in addition) sodium ribonucleate (40 mg/kg) through a tube into the stomach. Formation of lysyl-tRNA, leucyl-tRNA, and alanyl-tRNA in the liver and the skeletal muscles proved to be significantly greater in the animals which received ACTH together with sodium ribonucleate, as compared to that in the animals given the hormone alone. Hyperglycemia, hepatomegaly, and emaciation were less pronounced in the animals given both the preparations.

The "cobalt" variant of rainbow trout (Oncorhynchus mykiss) lacks most of the pars intermedia of the pituitary, and shows significant obesity with an enlarged liver and a fat accumulation in the abdominal cavity. Plasma levels of growth hormone, prolactin, and somatolactin were significantly lower in the cobalt variant than those in the normal trout. In contrast, plasma insulin level was four times higher than that in the normal. Plasma levels of total protein, free cholesterol, and triacylglycerol were higher in the cobalt, while those of glucose and fatty acids were not different from the normal levels. In the white muscle, red muscle, liver, and mesenteric fat, the cobalt showed higher contents of triacylglycerol than the normal fish. There was no significant difference in tissue contents of phosphatidylcholine between the two groups of the trout, except for that in the mesenteric fat, exhibiting significantly lower content than in the normal fish. Activity of triacylglycerol lipase in the liver in vivo was lower in the cobalt than that in the normal trout, while there was no significant difference between the two in the cultured liver slices. Desacetyl-alpha-MSH stimulated lipolysis of triacylglycerol similarly in the cultured liver slices from the normal trout and from the cobalt variant. Results from this study suggest that the lack of pars intermedia and the increased plasma level of insulin are involved in a depression of lipid mobilization and obesity in this variant of rainbow trout.

A 13-year-old, crossbreed dog presented with a history of recent onset polydipsia, progressive lethargy, weakness and reduced appetite. Blood tests showed raised concentrations of alkaline phosphatase and alanine aminotransferase with marginally low serum potassium. There was a leucocytosis with a mature neutrophilia and no eosinophils. Endocrine tests showed a normal aldosterone concentration and an exaggerated adrenocorticotropic hormone (ACTH) stimulation test, consistent with a diagnosis of hyperadrenocorticism (HAC). A diagnosis of adrenal-dependent HAC was made, based on the presence of a calcified mass involving the left adrenal gland, and hepatomegaly, on radiography and ultrasonography. The owners declined surgical adrenalectomy. Medical management with trilostane rapidly improved the clinical signs and normalised the serum chemistry. ACTH stimulation tests showed an improvement in post-ACTH cortisol concentrations and were used to make dose adjustments where necessary. At the time of writing, no adverse side effects had been seen and the dog remained well after 80 weeks of treatment.

Hyperadrenocorticism is a common endocrinopathy which results from the excessive production of cortisol by the adrenal cortex. In the majority of cases, this increased secretion of cortisol results from stimulation of the adrenal cortex by adrenocorticotrophic hormone secreted from the pituitary gland. In a smaller number of cases adrenal tumours are present. Clinical signs are variable but commonly include polydipsia and polyuria, polyphagia, obesity, a pendulous abdomen, hepatomegaly, alopecia, lethargy, weakness and anoestrus. Haematology, serum chemistry analysis and urinalysis should be performed on a dog with suspected hyperadrenocorticism. Finding a significant number of changes that are consistent with hyperadrenocorticism often allows a presumptive diagnosis to be made. Other tests can then be used to confirm the diagnosis and to help localise the cause, including liver biopsy, radiology, ultrasonography, gamma camera imaging, computed tomography, and measurement of blood and urine hormone levels. The ACTH stimulation test, low dose dexamethasone suppression test and measurement of the urine cortisol:creatinine ratio are used to assess whether hyperadrenocorticism is present. The high dose dexamethasone suppression test, measurement of plasma ACTH, corticotropin-releasing hormone stimulation test, and a modification of the urinary cortisol:creatinine ratio test are then implemented to determine the aetiology. The treatment of choice for adrenal neoplasia is surgical removal of the affected adrenal. On the other hand, pituitary hyperplasia or neoplasia may be treated either surgically, by bilateral adrenalectomy or hypophysectomy, or medically. The drug which is chosen most commonly for medical management is 1,1-dichloro-2(O-chlorophenyl)-2-(P-chlorophenyl) ethane (op'-DDD), which can be used to suppress adrenal function or to completely destroy the adrenal cortex. The antifungal agent ketoconazole also suppresses adrenal steroid synthesis and provides an alternative form of medical treatment for hyperadrenocorticoid dogs.
