Alcohol effects on the principal and clear cells of the caput epididymis of albino rats

Ultrastructural observations of principal cells of the epithelium lining of the proximal caput epididymis in experimental alcoholic albino rats at 180 days of treatment showed pyknotic nuclei, ill-defined cellular organelles and clusters of electrondense bodies, perhaps lysosomes. It was also verified for a progressive accumulation of lipid droplets initially in the basal and perinuclear cytoplasm and finally in the apical cytoplasm of principal cells at 60, 120 and 180 days of experimentation, respectively. The clear cells of alcoholic rats at 180 days showed the cytoplasm totally filled with lipid droplets. These findings were taken comparatively with the morphological features of the same epididymal cells in control (normal) rats.

Early age alcohol use and later alcohol problems in adolescents : individual and peer mediators in a bi-national study

This paper examines whether there is cross-national similarity in the longitudinal relationship between early age alcohol use and adolescent alcohol problems. Potential mechanisms underlying this relationship also are examined, testing adolescent alcohol use, low self-regulation, and peer deviance as possible mediators. Students (N = 1,945) participating in the International Youth Development Study, a longitudinal panel survey study, responded to questions on alcohol use and influencing factors, and were followed annually over a 3-year period from 2002 to 2004 (98% retention rate). State-representative, community student samples were recruited in grade 7 in Washington State, United States (US, n = 961, 78% of those eligible; Mage = 13.09, SD = .44) and Victoria, Australia (n = 984, 76% of those eligible; Mage = 12.93, SD = .41). Analyses were conducted using multiple-group structural equation modeling. In both states, early age alcohol use (age 13) had a small but statistically significant association with subsequent alcohol problems (age 15). Overall, there was little evidence for mediation of early alcohol effects. Low self-regulation prospectively predicted peer deviance, alcohol use, and alcohol problems in both states. Peer deviance was more positively related to alcohol use and low self-regulation among students in Victoria compared to students in Washington State. The small but persistent association of early age alcohol use with alcohol problems across both samples is consistent with efforts to delay alcohol initiation to help prevent problematic alcohol use. Self-regulation was an important influence, supporting the need to further investigate the developmental contribution of neurobehavioral disinhibition.

Alcohol Impairs Predation Risk Response and Communication in Zebrafish

The effects of ethanol exposure on Danio rerio have been studied from the perspectives of developmental biology and behavior. However, little is known about the effects of ethanol on the prey-predator relationship and chemical communication of predation risk. Here, we showed that visual contact with a predator triggers stress axis activation in zebrafish. We also observed a typical stress response in zebrafish receiving water from these conspecifics, indicating that these fish chemically communicate predation risk. Our work is the first to demonstrate how alcohol effects this prey-predator interaction. We showed for the first time that alcohol exposure completely blocks stress axis activation in both fish seeing the predator and in fish that come in indirect contact with a predator by receiving water from these conspecifics. Together with other research results and with the translational relevance of this fish species, our data points to zebrafish as a promising animal model to study human alcoholism. © 2013 Oliveira et al.

Sikiöaikana päihteille altistuneiden lasten kasvuympäristö ja kehitys

Life of children exposed to alcohol or drugs in utero This study focused on the growth environment, physical development and socio-emotional development of children, aged 16 and under, who had been exposed to alcohol (n=78) or drugs (n=15) in utero. The aim of the study was to obtain a comprehensive picture of the living conditions of these children and to examine the role of the growth environment in their development. The study was carried out using questionnaires, written life stories and interviews. Attachment theory was used as a background theory in the study. Over half of the children exposed to alcohol were diagnosed with foetal alcohol syndrome (FAS), one quarter was diagnosed with foetal alcohol effects (FAE), and one fifth had no diagnosis. Most of the children exposed to drugs had been exposed to either amphetamines or cannabis, and a smaller number to heroin. Some of the children exposed to alcohol were mentally handicapped or intellectually impaired. The children exposed to drugs did not exhibit any serious learning difficulties but a considerable number of them had socio-emotional development problems. Language and speech problems and attention, concentration and social interaction problems were typical among both the children exposed to alcohol and those exposed to drugs. Only one child had been placed into long-term foster care in a family immediately after leaving the maternity hospital. In biological families there had been neglect, violence, mental health problems, crime and unemployment, and many parents were already dead. Two of the children had been sexually abused and four were suspected of having been abused. From the point of view of the children's development, the three most critical issues were 1) the range of illnesses and handicaps that had impaired their functional capacity as a result of their prenatal exposure to alcohol, 2) child's age at the time of placement on a long-term basis, and 3) the number of their traumatic experiences. The relationship with their biological parents after placement also played a role. Children with symptoms were found in all diagnosis categories and types of exposure. Children with the smallest number of symptoms were found among those who had never lived with their biological parents. Almost all children were exhibiting strong symptoms at the time of placement in foster care. In most cases, they were behaving in a disorderly manner towards others, but some children were withdrawn. The most conspicuous feature among those with the most severe symptoms was their disorganized behaviour. Placement in a foster family enhanced the children's development, but did not solve the problems. The foster parents who brought these children up did not receive as much therapy for the children and support for the upbringing as they appear to have needed. In Finland, transfer to long-term custody is based on strict criteria. The rights of children prescribed in the child protection law are not fulfilled in practice. Key words: FASD, FAS, FAE, alcohol exposure, drugs exposure, illegal drugs, early interaction, child development, attachment

O consumo de álcool entre os adolescentes estudantes de escolar privadas católicas de Natal-RN

This study has an object the understanding of the alcohol phenomenon consumption that occurs among teenagers. It is adopted as research locus catholic private schools of Natal - RN, which receive pupils proceeding from the social groups pertaining to the classes taken from Natal private schools. The researched public corresponds to 87 teenagers, who had answered to a mixing questionnaire, with open and closed questions. The research uses as a procedure the intentional election, which for the access easinesses privileges subjects who, at the moment of the research accomplishment, reveal to be in condition to participate of it. The study presents quantitative and qualitative character. It presents the following objectives: 1-Identify in which circumstances the teenagers make alcoholic beverage use; 2 -To identify the knowledge that the teenagers have on the alcohol effects; 3 -To identify the performance role of the school institution on the prevention of alcohol use by teenagers. The analysis method used corresponds to the one called answers interpretation method. Regards to the theoretical-methodological support, the Social Control Theory and the Symbolic Interactionism Theory are adopted as referential. Its contained chapters are organized in the following way: The first chapter approaches the situation of drugs adolescent consumption in general and the social confrontation of this situation. The second chapter presents sociocultural aspects of the alcohol consumption and the description of some of the researched public characteristics. The third chapter emphasizes the school and its performance next to the teenagers and the society in general, towards the prevention and combat of the alcohol use, as well as of other drugs
