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 ...
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 ...
Ornithine decarboxylase activity in retinal explants of goldfish undergoing optic nerve regeneration
(Elsevier, 1981-06)
Retinal explants cultured in the presence of fetal calf serum (FCS) exhibit an increase in the activity of ornithine decarboxylase which is maximal several hours after explanation. The measured activity of this enzyme is ...
Short-term effects of marijuana smoking on cognitive behavior in experienced male users
(Springer-Verlag, 1973-03)
The effects of smoking marijuana on the ability to use abstract concepts was tested in 12 experienced marijuana users. Each subject was tested three times, after smoking prepared 300 mg cigarettes containing either 0, 1.5 ...
Effects of tobacco smoking on the topographic EEG I
(Elsevier, 1994-09)
1. 1. The EEG and cardiovascular effects of smoking tobacco cigarettes of varying nicotine content were studied in Japanese chronic tobacco smokers.2. 2. Thirteen female and fifteen male adult normal volunteers were recruited ...
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 ...
Developmental changes in taste responses from glossopharyngeal nerve in sheep and comparisons with chorda tympani responses
(Elsevier, 1983-12)
To learn whether there are developmental changes in salt and acid taste responses from the posterior tongue, we recorded from the glossopharyngeal nerve, which innervates taste buds in circumvallate papillae, in sheep ...
Differential effects of pentobarbital, ethyl alcohol, and chlorpromazine in modifying reticular facilitation of visually evoked responses in the cat
(Elsevier, 1969-01)
Cortical visually evoked responses (VER) elicited by electrical stimulation of the ipsilateral optic tract were dramatically facilitated by stimulation of the midbrain reticular formation. This facilitation depended on the ...
Some effects of muscarinic cholinergic blocking drugs on behavior and the electrocorticogram
(Springer-Verlag, 1964-03)
Results are presented for the effects of drugs with muscarinic cholinergic blocking actions, both central and peripheral (scopolamine and 1-hyoscyamine) and primarily peripheral (methyl atropine and methyl scopolamine), ...
