A double-blind withdrawal trial in 41 chronic schizophrenic outpatients was carried out during 6 months. Depot neuroleptics (fluphenazine decanoate or flupenthixol decanoate) were compared with placebo to evaluate clinical and neurological effects during continued therapy and during withdrawal. The drugs were significantly more effective than placebo in(More)
BACKGROUND Healthy first-degree relatives of patients with major depression (rMD+) show brain structure and functional response anomalies and have elevated risk for developing depression, a disorder linked to abnormal serotonergic neurotransmission and reward processing. METHOD In a two-step functional magnetic resonance imaging (fMRI) investigation, we(More)
Hyperbaric oxygen preconditioning (HBO-PC) can protect the heart from injury during subsequent ischemia. The presence of high loads of venous gas emboli (VGE) induced by a rapid ambient pressure reduction on ascent from diving may cause ischemia and acute heart failure. The aim of this study was to investigate the effect of diving-induced VGE formation on(More)
Decompression sickness is initiated by gas bubbles formed during decompression, and it has been generally accepted that exercise before decompression causes increased bubble formation. There are indications that exercise-induced muscle injury seems to be involved. Trauma-induced skeletal muscle injury and vigorous exercise that could theoretically injure(More)
Sixteen out of 19 patients suffering from chronic anergic schizophrenia completed a placebo-controlled cross-over study with lysine-8-vasopressin (LVP), following a schedule of 1 week of placebo, 3 weeks of LVP, starting with 22.5 IU/day, gradually increased to 67.5 IU/day, and finally 4 weeks of placebo. The psychic state was evaluated with the Brief(More)
A venous blood sample and an umbilical cord blood sample were obtained from five young women treated with the neuroleptic drug, cis(Z)-flupentixol decanoate in Viscoleo (intramuscularly) or flupentixol (orally) at the time of giving birth. In two cases amniotic fluid was also obtained, and from three of the mothers milk and simultaneous blood samples were(More)
Two pharmacolkinetic parameters viz. the minimum serum concentration in the dosage interval and the sera under the serum concentration curve have been correlated to 14 parameters for clinical outcome, viz. total points and factor points from the three rating scales, BPRS, CPRS, and side effects scale, in a double blind clinical trial of clopenthixol and(More)
Serum concentrations of zuclopenthixol were determined in a group of 20 patients treated with a depot preparation, zuclopenthixol decanoate in Viscoleo. Clinical assessments according to a Clinical Global Impression (CGI) scale, Comprehensive Psychological Rating Scale (CPRS), 16-item subscale for schizophrenia, and the UKU side effect scale were performed(More)
BACKGROUND Use of ultrasound in brain tumor surgery is common. The difference in attenuation between brain and isotonic saline may cause artifacts that degrade the ultrasound images, potentially affecting resection grades and safety. Our research group has developed an acoustic coupling fluid that attenuates ultrasound energy like the normal brain. We aimed(More)
