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)
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)
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)
Platelet monoamine oxidase (MAO) activity levels were determined before and 180 minutes after ingestion of ethyl alcohol in 30 healthy men aged 21 to 25 years. The subjects included 15 men with alcoholic first-degree relatives who were matched by demography, height-weight ratio, and drinking history with 15 control subjects who had no family history of(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)
Cerebrospinal fluid was collected from the lateral ventricles and cisternal space from beagle dogs under light pentobarbital anesthesia. Homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA), and 3-methoxy-4-hydroxyphenylglyco-sulfate (MOPEG-SO4) levels in the liquor taken from these two regions were evaluated, and the ventricular-cisternal ratio(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)
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)
