Preface This report constitutes an account of the project PINA Mortality Risk. The aim of the project has been to examine lay-people's perception of their own road-traffic and overall lmortality risk. The project is joint work between Henrik Andersson (VTI) and Summary Individuals' perception of their own road-traffic and overall mortality risks are(More)
Using data on Swedish adolescents, this study examines (1) perceptions of the addictiveness and mortality risk of smoking, (2) the effects of these perceptions on smoking behaviour, and (3) the role of various smoking risk information sources. The average respondent believed that 46 out of 100 smokers would die from diseases caused by their smoking. As to(More)
A combined biochemical and behavioral study was performed postnatally on albino rats. An almost linear increase in total motor activity was observed from 1 to 15 days of age followed by a pronounced decrease in motor activity between days 15 and 18. The in vivo rate of tyrosine hydroxylase activity in whole brain was estimated by means of measuring(More)
Various biochemical characteristics of the developing GABA system was studied in rats from 1 to 60 days of age. Endogenous GABA concentrations were high in the limbic system, midbrain, brain stem and spinal cord at birth. Until 7 days of postnatal age, GABA concentrations generally decreased, thereafter an increase was seen and at 60 days of age the GABA(More)
4, 14 and 28 days old rats were exposed to hypoxic environment of 6% O2-94% N2 for 30 min. Tyrosine hydroxylase and tryptophan hydroxylase activity was studied in different brain regions (hemispheres, striatum, midbrain and brainstem in vivo by measuring the accumulation of dihydroxyphenylalanine (Dopa) and 5-hydroxytryptophan (5-HTP) respectively, after(More)
Neonatal rats were exposed to 20 or 30 min of total or partial oxygen deprivation. During asphyxia and subsequent recovery the endogenous levels of tryptophan and 5-hydroxytryptamine (5-HT, serotonin) were measured. The activity of tryptophan hydroxylase, the first and rate limiting enzyme in the 5-HT synthesis pathway, was studied in vivo by measuring the(More)
Cross-sectional survey data on Swedish adolescents aged 12-18 was used to estimate the link between individual social capital and smoking, illicit drug use and binge drinking. Major conclusions drawn were (1) that social capital, indicated by measures of social participation and trust, was negatively correlated with the probability of smoking and illicit(More)
