This study examined the neurophysiological effects of cannabis. Cerebral blood flow (CBF) was measured in 12 long-term cannabis users shortly after cessation of cannabis use (mean 1.6 days). The findings showed significantly lower mean hemispheric blood flow values and significantly lower frontal values in the cannabis subjects compared to normal controls.… (More)
OBJECTIVE There is a growing interest for matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) in plasma as novel biomarkers in coronary artery disease (CAD). We aimed to identify the sources of MMP-8, MMP-9, TIMP-1 and TIMP-2 among peripheral blood cells and further explore whether gene expression or protein release was altered in patients… (More)
In a patient group of 90 suicide attempters, 18% showed an impaired blood-CSF barrier; of these 16 patients, all but one were younger than 45 years. When compared with 105 healthy controls, a significant difference in impairment of the blood-CSF barrier, between patients and controls, was seen only in those younger than 45 years (z = -2.66; P < 0.01).… (More)
BACKGROUND Matrix metalloproteinase (MMP)-9 may play a central role in the development and progression of atherosclerosis. Emerging evidence also indicates an association between MMP-9 and depressive symptomatology. Here, we investigated whether expression of MMP-9 and its inhibitors in blood mononuclear cells and plasma were related to depressive symptoms… (More)
Stress and inflammation are both important risk factors for coronary artery disease (CAD). However, the susceptibility to stress-induced inflammation and its determinants have been little explored in patients with CAD. Here, our aim was to study the stress-induced inflammatory response, more precisely the early release of matrix metalloproteinase (MMP)-9,… (More)

The concentrations of chlorpromazine and some of its metabolites in blood plasma and CSF from chlorpromazine-treated schizophrenics with different therapeutic results were studied. Compared to a good responder a poor responder showed very high levels of the inactive metabolite chlorpromazine sulphoxide in the CSF.
