Pharmacological challenges were separated by a minimum of 72 h. Plasma cortisol levels following ethanol in sons of alcoholics and controls. Given this relationship, we assayed ACTH from the same samples. The effects of pharmacological challenges on plasma DOC were analyzed using linear mixed-effect models with monkey as the subject variable and experimental phase three levels: baseline, induction, and self-administration as the independent variables. Variations in adrenal androgen production among nonhuman primates. Figure 3. Brain Res Rev — Psychoneuroendocrinology — All analyses were conducted using R 2. Thus, our blood collection procedure provides a stable condition under which the native circuitry regulating the adrenal output appears to be in homeostasis at baseline and can serve as a comparative basis across the experimental phases.

    Google Scholar. The individual timecourses show that both challenge doses of ethanol blunted circulating DOC. Developmental, diurnal and oestrous cycle-dependent changes in the activity of liver enzymes.

    All animals were trained to participate in awake venipuncture and had been doing so each week in their home cage for over 6 months prior to collection of the samples reported here.

    The DOC response is summarized across the experimental phases by area under the curve A.

    In a study using low stress, resting conditions i. Toggle navigation. During both baseline and induction the lowest DOC concentration was measured at min following the challenge. Additionally, an extensive literature describes the consequences of long-term alcohol consumption on HPA axis function. Adaptation of the hypothalamic-pituitary-adrenal axis to chronic ethanol stress. All challenges of the HPA axis, except for the dexamethasone challenge, were conducted in the primate chairs.

    As the biological response to stress is the activation of the HPA axis, the Hoek HW, van Hoeken D: Review of the prevalence and incidence of eating disorders.

    Peak DOC was significantly dampened during ethanol induction 0.

    One well-documented consequence of HPA axis over-activation is decreased sensitivity to glucocorticoid negative feedback 10 The HPA axis response to ethanol has been suggested as a risk factor for developing alcoholism, and acute, low doses of ethanol suppress cortisol more among alcohol-drinking sons of alcoholics than controls Psychoneuroendocrinology —9.

    Summaries of the ethanol self-administration data are available online www.

    The current dataset is an extensive investigation of the mechanisms related to HPA axis activation that regulate DOC concentration over the course of ethanol induction and self-administration in non-human primates. In a study using low stress, resting conditions i. Differential hypothalamic-pituitary-adrenal activation of the neuroactive steroid pregnenolone sulfate and deoxycorticosterone in healthy controls and alcohol-dependent subjects. The apparent discrepancies in regulation of DOC responses following long-term ethanol exposure might be the result of species differences or the different experimental procedures, i.

    Thus, our blood collection procedure provides a stable condition under which the native circuitry regulating the adrenal output appears to be in homeostasis at baseline and can serve as a comparative basis across the experimental phases.

    ACTH Cortrosyn; 0. Steroids — These data show that HPA axis modulation of the neuroactive steroid precursor DOC is markedly altered by the schedule induction of ethanol drinking and long-term voluntary ethanol self-administration.

    Specifically, DOC is increased by injections of naloxone hypothalamic and CRH pituitarysuppressed by dexamethasone hypothalamic, pituitary, adrenalbut unchanged by ACTH adrenal or ethanol [1.

    Circulating DOC in human and non-human primates is mainly of adrenal origin, and its secretion is regulated by the HPA axis, in a manner similar to cortisol 2633 —
