    Notes: The present study sought to investigate the effects of preexercise stretching on delayed onset muscle soreness (DOMS), i.e. soreness, tenderness and loss of muscle force, that usually occurs after strenuous or unaccustomed eccentric exercise. Ten female volunteers performed 10 sets of 10 maximal isokinetic eccentric contractions for knee flexion with both legs after a 5-min ergometer cycling warm-up. Prior to the exercise for one leg, randomly chosen, 4×20 s of static stretching for the hamstring muscle group was implemented. Rated soreness, tenderness on algometer pressure and loss of maximal eccentric contractile force was evaluated preexercise and 24, 48 and 96 h postexercise. The exercise bout produced severe DOMS, with parameters peaking and troughing at 48 h postexercise. However, no significant differences were found, regarding any of the parameters, when comparing stretched and nonstretched legs. The present study thus suggests that preexercise static stretching has no preventive effect on the muscular soreness, tenderness and force loss that follows heavy eccentric exercise.

    Notes: Summary In a single-blind pilot study 0.4 mg naloxone i.v. was found temporarily to reduce or abolish auditory hallucinations in four cases of chronic schizophrenia whereas saline was without effect. In one of these patients there was a similar reversal also of her visual hallucinations. Two additional cases who denied hearing voices before the injections, reported no subjective effects.

    Notes: Abstract  This paper is the consensus of a workshop that critically evaluated the utility and problems of video playbacks as stimuli in studies of visual behavior. We suggest that video playback is probably suitable for studying motion, shape, texture, size, and brightness. Studying color is problematic because video systems are specifically designed for humans. Any difference in color perception must lead to a different color sensation in most animals. Another potentially problematic limitation of video images is that they lack depth cues derived from stereopsis, accommodation, and motion parallax. Nonetheless, when used appropriately, video playback allows an unprecedented range of questions in visual communication to be addressed. It is important to note that most of the potential limitations of video playback are not unique to this technique but are relevant to all studies of visual signaling in animals.

    Notes: Abstract In two patients with chronic schizophrenia, who were on clozapine medication for more than 6 months, a sudden withdrawal of the drug resulted in a very pronounced deterioration of the psychosis within 24–48 h. The most prominent symptoms were auditory hallucinations and persecutory ideas and one patient tried to commit suicide. These observations are interpreted as supersensitivity psychoses induced by the very effective clozapine treatment.

    Notes: Abstract Remoxipride is a novel substituted benzamide derivative with specific dopamine-(D2)-receptor blocking properties and selective action on brain mesolimbic functions. Ten inpatients with a DSM-III diagnosis of schizophrenia were treated with the drug in a 6-week open-label study. After 1 week placebo washout, the patients were given stepwise increased doses from 20 to 100 mg t.i.d. Most patients showed a clinically significant improvement; the mean scores in the Brief Psychiatric Rating Scale decreased from 25.8 at baseline to 11.3 at endpoint. Few adverse events were recorded and the rated extrapyramidal symptoms were lower at endpoint than at baseline. No abnormalities in clinical chemistry, haematology, cardiovascular assessments or EEG recordings were seen.

    Notes: Abstract Nine psychotic patients under continuous oral treatment with haloperidol were randomly given a test dose of 1.5–5 mg haloperidol orally and/or intravenously. Serum levels of haloperidol were determined by high performance liquid chromatography and serum concentration data obtained were submitted to pharmacokinetic analysis. The steady state concentration ratio between blood and plasma was determined and found to be 0.79±0.03. The blood clearance was then calculated to be 550±133 ml/min. The mean hepatic extraction ratio was intermediate (0.37). Consequently, for a drug mainly eliminated by hepatic metabolism like haloperidol, the total blood clearance and the extent of oral bioavailability can be affected by changes in hepatic blood flow, hepatic enzyme activities and drug binding. During continuous oral treatment with haloperidol, however, it can be shown that changes in the total metabolic capacity of the liver due to hepatic enzyme induction or inhibition should be important for the therapeutic effects of haloperidol. The volume of distribution at steady state (Vdss) was large (7.9±2.5 l/kg). The terminal half-life was 18.8 h after intravenous and 18.1 h after oral administration. The oral bioavailability (0.60±0.18) were in accordance with previous results in healthy subjects. A mean lag time after oral dose was 1.3±1.1 h and a longer absorption half-life (1.9±1.4 h) was found in the patients compared with healthy volunteers.

    Notes: Summary The clinical pharmacokinetics of clozapine, an atypical neuroleptic, was evaluated in 10 chronic schizophrenic male patients after intravenous and oral administration. The mean equilibrium-state concentration ratio between blood and plasma was experimentally determined to be 0.87. The average values for blood clearance, hepatic extraction ratio and oral bioavailability were 250 ml/min, 0.2 and 0.27, respectively. Plasma concentration peaked on average at 3 h. The mean volume of distribution at steady-state and the terminal half-life was 1.6 l/kg and 10.3 h, respectively. A large fraction of the dose is most probably metabolized by some extrahepatic presystemic routes. The large inter-individual variability in the bioavailability and clearance is probably the main reason for large variation in the steady-state plasma level in patients receiving the same oral dosage regimen.

    Notes: Abstract The Comprehensive Psychopathological Rating Scale (CPRS) was used to determine symptomatology in 145 schizophrenic patients. In 40 of these patients the Schedule for Assessment of Negative Symptoms (SANS) was also applied in order to determine which items in the CPRS represent negative schizophrenic symptoms. Of the patients, 115 were drug-free and 30 were treated with major transquilizers at the time of the rating. A principal component analysis with oblique solution and Varimax rotation grouped the items from CPRS into ten factors. These factors were subsequently correlated to the total scores of the SANS. When a factor showed a positive correlation with the SANS, the individual items within the factor were examined for correlation to both the subscales and the total SANS scores. Of the 33 items, 5 used in the CPRS showed a positive correlation with the SANS and were therefore considered to represent negative symptomatology in schizophrenia. These items were withdrawal, reduced speech, lack of appropriate emotions, slowness of movements and indecision. The items were grouped as a negative symptom subscale in the CPRS.
