  2. 1. Endothelin-1-immunoreactive protein and neuroendocrine differentiation and nerve supply in human non-neoplastic and neoplastic adrenal cortex : Immunohistochemical, ultrastructural, and biochemical findings

    Author : Qing Li; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; adrenal cortex; human; endothelin-related protein; innervation; neuroendocrinedifferentiation; immunohistochemistry; electron microscopy; biochemistry; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Abstract : 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.

  4. 2. Studies on stress in African green monkeys (Cercopithecus aethiops) : Stress associated cortisol and prolactin levels, lymphocyte modulation and pathological changes in adrenal cortex, stomach and hippocampus in the African green monkey (C. aethiops)

    Author : Mbaruk Abdalla Suleman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; adrenal cortex; capture; confinement; cortisol; husbandry; housing; hippocampus; lymphocytes; prolactin; stomach; stress; wild; African green monkeys; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : 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.

  5. 3. Adrenal Bioactivation and Toxicity of 3-MeSO2-DDE, o,p´-DDD and DMBA Investigated in Tissue Slice Culture

    Author : Örjan Lindhe; Jan Alexander; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; adrenal cortex; 3-MeSO2-DDE; o; p´-DDD; DMBA; bioactivation; binding; toxic; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Abstract : 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.

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

    Author : Linda Engström; Anders Blomqvist; Tomas Hökfelt; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inflammation; brain; adrenal gland; stress; lipopolysaccharide; interleukin-1; Neurobiology; Neurobiologi;

    Abstract : 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.

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

    Author : Veronica Lindström; Ingvar Brandt; Ulrika Bergström; Eva Brittebo; Hans Tjälve; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Toxicology; 3-methylsulphonyl-DDE; o; p -DDD; CYP11B1; adrenal cortex; tissue-specific toxicity; bioactivation; kinetics; Y-1 cells; Toxikologi; Biology; Biologi;

    Abstract : 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). READ MORE
