The distribution of platelet monoamine oxidase (MAO) activity is examined in a large cohort of 18-year-olds from a college setting. A mixture of three distributions is needed to describe the data, even when a power transformation is used to remove skewness in the distribution. This is compatible with MAO activity being controlled by a single major locus(More)
The authors studied platelet monoamine oxidase (MAO) activity in 29 schizophrenic inpatients and 26 schizophrenic outpatients during a 4-week double-blind trial of chlorpromazine with imipramine or thiothixene with placebo. The found that significantly more schizophrenic patients than normal control subjects had low platelet MAO activity after 4 weeks.(More)
Postmortem levels of native neopterin (D-erythro-neopterin) were measured in cerebral cortical samples from 44 human immunodeficiency virus type 1-infected and eight uninfected, nonneurological control patients. Cerebral cortical gray and white matter neopterin levels for the controls ranged from 0.5 to 7.2 pmol/mg of protein in contrast to neopterin levels(More)
The effects of possible confounding factors on endogenous breath acetaldehyde levels were examined in alcoholic and non-alcoholic subjects. Demographic characteristics, family history for alcoholism, smoking and drinking history, and breath acetaldehyde levels were assessed. Differences in endogenous breath acetaldehyde levels could not be attributed to(More)
Endogenous (fasting) breath acetaldehyde levels were assessed as a discriminator between alcoholic and non-alcoholic subjects. The influence of smoking as a potential confounding variable on breath acetaldehyde was determined. Individuals with a history of smoking and/or drinking had higher endogenous breath acetaldehyde levels as compared to controls. Mean(More)
Since highly differentiated cells of mammalian immune systems reportedly have binding sites for a variety of neurohumoral agents, we investigated parameters related to possible existence of dopamine receptors on murine lymphoid cells. Using a dopamine antagonist, [3H]spiroperidol, we found evidence for displaceable binding on mouse spleen cells. Total and(More)
Serum prostaglandin E (PGE) levels were measured in rats immediately following electrical stimulation of the mesencephalic periaqueductal gray (PAG) region and the nucleus raphe magnus (NRM) and compared to controls. An additional group received aspirin prior to PAG stimulation. A significant increase in serum PGE levels was found after stimulation of the(More)
