Postnatal ontogeny of acetylated and non-acetylated B-endorphin in rat pituitary
(Elsevier, 1983)
Extracts of the anterior lobe and intermediate lobe of postnatal (P) (Day P1, P7, P14, P21, P28, P35, P42) and adult male Spraque-Dawley rats were analyzed by both a Beta-endorphin (B-END) radioimmunoassay and a radioimmunoassay ...
The effects of footshock stress on regional brain dopamine metabolism and pituitary [beta]-endorphin release in rats previously sensitized to amphetamine
(Elsevier, 1987-07)
The repeated intermittent administration of amphetamine (AMP) produces an enduring enhancement in the response of dopamine (DA) systems in the brain to a subsequent "challenge" with amphetamine. However, former amphetamine ...
The morphology of the seminiferous tubules of mammalia. Preliminary note
(Wiley Subscription Services, Inc., A Wiley Company, 1913-06)
No Abstract.
Cortisol response to a psychological stressor and/or nicotine
(Elsevier, 1990-05)
The effects of a psychological stressor and nicotine upon corticosteroid release were investigated using a full factorial, repeated-measures design in eight moderate smokers. Sessions involved the presentation of either ...
Selective inhibition by alcohol and cortisol of natural killer cell activity of lymphocytes from cord blood
(Elsevier, 1994-12)
1. 1. The immunosuppressive effects of drugs such as alcohol or hormones such as cortisol may be age-related. To test this hypothesis, the authors investigated the in vitro effects of ethanol (EtOH) and cortisol on Natural ...
Effects of morphine treatment on pro-opiomelanocortin systems in rat brain
(Elsevier, 1990-06-11)
In previous studies to determine whether chronic opiate administration might negatively feedback upon endogenous opioid systems in the CNS, investigators found no changes in steady-state concentrations of opioid peptides ...
Development of hypothalamic opioid neurons: A combined immunocytochemical and [3H]thymidine autoradiographic study
(Elsevier, 1985-02)
Using a combined technique of immunocytochemistry and [3H]thymidine autoradiography, we have determined the "birth-date" of opioid peptide containing neurons in three hypothalamic nuclei. These include proopiomelanocortin ...
Dexamethasone attenuation of the cortisol response to nicotine in smokers
(Springer-Verlag, 1990-06)
The effect of corticosteroids upon the cortisol response to nicotine from smoking was investigated in five heavy smokers. Corticosteroid activity was manipulated by administering dexamethasone, a synthetic glucocortoicoid ...
Immunocytochemical localization of pro-opiomelanocortin-derived peptides in the adult rat spinal cord
(Elsevier, 1986-07-16)
A dispersed descending pro-opiomelanocortin (POMC) fiber system has been demonstrated by peroxidase-antiperoxidase (PAP) immunocytochemistry in the adult rat spinal cord. [beta]-endorphin, adrenocorticotrophic hormone ...
