    Sammanfattning : The occurrence and distribution of endothelin (ET)-1-immunoreactive (ir) protein, neuro-endocrine markers and neurohormonal peptides in endocrine cells and nerves in human non-neoplastic and neoplastic adrenal cortex are described.ET-1-ir cell groups were regularly seen in human adrenal cortex, mainly in zona fasciculata, but not in the medulla.

    Sammanfattning : African green monkeys (AGMs) are highly susceptible to captivity-induced stress. An investigation of spontaneous deaths of laboratory confined AGMs at the Institute of Primate Research, Nairobi, Kenya over a period of 7.5 years documented mild to severe gastric mucosal erosions and ulcers in 83 of 260 (32%) necropsies.

    Sammanfattning : I developed a precision-cut adrenal slice culture procedure to investigate cytochrome P450 (CYP) catalysed irreversible binding and adrenocorticolytic effects in human, rodent, and fish adrenal tissue, ex vivo. Autoradiography and radioluminography of exposed tissue slices showed that the potent adrenal toxicant 3-methylsulphonyl-2,2´-bis(4-chlorophenyl)-1,1´-dichloroethene (MeSO2-DDE) causes a selective metabolite binding in zona fasciculata (ZF), which is diminished by the CYP11B1 inhibitor metyrapone.

  4. 4. Inflammation-Induced Gene Expression in Brain and Adrenal Gland

    Författare :Linda Engström; Anders Blomqvist; Tomas Hökfelt; Linköpings universitet; []

    Sammanfattning : The autonomic nervous system serves to maintain a constant inner environment, a process termed homeostasis. Thus, in response to the homeostatic challenge posed by infectious agents, the autonomic nervous system answers to signals from the immune system and elicits adaptive physiological and behavioral reactions.

  5. 5. Adrenocorticolysis Induced by 3-MeSO2-DDE : Mechanisms of Action, Kinetics and Species Differences

    Författare :Veronica Lindström; Ingvar Brandt; Ulrika Bergström; Eva Brittebo; Hans Tjälve; Uppsala universitet; []

    Sammanfattning : The DDT metabolite 3-methylsulphonyl-DDE (3-MeSO2-DDE) induces cell death specifically in the adrenal cortex of mice after a cytochrome P45011B1 (CYP11B1)-catalysed bioactivation. This substance is not only an environmental pollutant, but also a suggested lead compound for an improved chemotherapy of adrenocortical carcinoma (ACC). LÄS MER
