As possíveis relações entre desenvolvimento moral e uso de crack por adolescentes

The dependency of psychoactive substances whether licit or illicit, among adolescents is a topic that has aroused much discussion today. One of the psychoactive substance that has caught the attention of authorities and experts, its potential dependence, increasing the number of addicts and speed with which triggers the human degeneration is the crack (a derivative of cocaine - Erythroxylon coca), used via the smoked administration. Understanding the phenomenon of increasing their use requires an analysis of the concepts of addiction throughout history, current research encompassing scientific findings in epidemiology and statistics involving several types of pharmacological substances, and especially the analysis of data related specifically to crack the focus of our theme. In order to contribute to ongoing discussions and offer possible alternatives for effective intervention, especially in schools, we conducted a survey that sought to find evidence of a possible relationship between crack use and moral reasoning. Since our work specifically theoretical nature, we use to reach our goals, assumptions, two researchers in the concept of human morality: Jean Piaget (1994) and Lawrence Kohlberg (1992) both traveling within the proposed cognitive-evolutionary human development. For an understanding of the proposals of these two researchers, we use research to (Lepre, 2005), as guiding thesis of this work. The results presented indicate that adolescents who use crack are very close to a level of moral reasoning pre-conventional and conventional, although it is important to state that more accurate results require further research on the subject, including those involving field research. Yet we can conclude that prevention must go through a dialogue that privileges the moral education as possible means of effective intervention against the use of crack, allowing the construction of autonomy...

Detecção da procedência de plantas psicoativas pelos isótopos estáveis do nitrogênio (15n) e oxigênio (18o)

This research examines the merits of hallucinogenic plants considered and/or psychoactive substances, such as Cannabis sativa and Ipomoea violacea, using the isotope rates of stable isotope of oxygen (18O) and nitrogen (15N), continuing projects already developed by the research group at the Center for Stable Isotope (CIE), which evaluated the isotopes carbon-13. This paper helps in creating a database that we intent to use in evaluation of each plant merit. Through the IRMS (Isotope-Ratio Mass Spectrometry) technique, it has shown that some of the 24 samples of marijuana (Cannabis sativa L.) evaluated were similar to those grown in the regions of Fairbanks and Tanacross Alaska, USA. In turn, the 50 samples of Ipomoea violacea, coming from Botucatu (SP) and Três Lagoas (MS), got their differences detected, in order to clearly identify the discrepancies between their growing regions. Thus, it was possible not only to track the geographical differences between marijuana samples collected from different regions, but also evaluate the isotopic variation of leaf, flower and seed of Ipomoea violacea. With this database, it was possible to determine the origin region of the drug and/or detect where the cultivation was carried out, aiding in the search of the traffic control agencies, such as the Federal Police in Brazil

Drug addictions and sexual violence in childhood and adolescence: analyzing life stories

The sexual abuse suffered in childhood and adolescence, in addition to damage to physical and psychological health of the victim, is considered as an important risk factor for alcohol and drugs addiction, development of psychopathology and psychosocial damage in adulthood. In addition to the pain and humiliation that are submitted by the abuse, children and adolescents also experience shame and guilt which require them to adopt coping strategies to endure those feelings. The use of psychoactive substances is a recognized way of dealing with the pains of living. This work, which is of narrative style, analyses and discusses, through five case reports, chemical dependency as a result of sexual abuse suffered in childhood and/or adolescence. The eight subjects in this study are male and have suffered sexual violence in this age period of life. Their ages range from 23 years to 39 years, and all are admitted to a therapeutic community in a city in the interior of Sao Paulo state, in Brazil, for treatment of chemical dependency, being met by the Department of Psychology. The reasons for the choice of the participants for treatment modality for patients are: difficult to stop using drugs, even unwilling to take it, they have easy access to it; the feeling of losing control over their lives; by successive losses as a result of drug use, and for fear that their lives had a tragic ending. With the exception of two participants, the others do not classify that as a child suffered sexual violence. However, all attribute that facilitated their entry into the world of drugs. Seven participants experienced such violence in childhood (between 7 years and 9 years) and adolescence (age 14). The attackers were people closed to the victims—in the case of two victims, their families, with the exception of one participant who was raped by a stranger. Six participants declared themselves as homosexual. Another participant does not claim to be homosexual, but presents difficulties in terms of sexuality. Two participants are HIV positive. The start of psychoactive substances use occurred during adolescence (12 years to 17 years). The participants see drugs as an anesthetic to the pain of the soul, a way to get pleasure, but they get charged expensively, as it increases the feeling of emptiness, guilt, helplessness, worthlessness and hopelessness. Although participants have sought help to deal with addiction, it is noted that throughout the life course the issue of sexual violence was not treated. It was noted that the patients have a double stigma in society: the issue of drugs addiction and the orientation of sexual desire, because the majority of participants are homosexual. The results reinforce the need for effective action geared to accommodate the victims of sexual violence and effective preventive measures to prevent children and adolescents from being abused.

Reduction capability of soil humic substances from the Rio Negro basin, Brazil, towards Hg(II) studied by a multimethod approach and principal component analysis (PCA)

This paper characterizes humic substances (HS) extracted from soil samples collected in the Rio Negro basin in the state of Amazonas, Brazil, particularly investigating their reduction capabilities towards Hg(II) in order to elucidate potential mercury cycling/volatilization in this environment. For this reason, a multimethod approach was used, consisting of both instrumental methods (elemental analysis, EPR, solid-state NMR, FIA combined with cold-vapor AAS of Hg(0)) and statistical methods such as principal component analysis (PCA) and a central composite factorial planning method. The HS under study were divided into groups, complexing and reducing ones, owing to different distribution of their functionalities. The main functionalities (cor)related with reduction of Hg(II) were phenolic, carboxylic and amide groups, while the groups related with complexation of Hg(II) were ethers, hydroxyls, aldehydes and ketones. The HS extracted from floodable regions of the Rio Negro basin presented a greater capacity to retain (to complex, to adsorb physically and/or chemically) Hg(II), while nonfloodable regions showed a greater capacity to reduce Hg(II), indicating that HS extracted from different types of regions contribute in different ways to the biogeochemical mercury cycle in the basin of the mid-Rio Negro, AM, Brazil.

Influence of alkaline extraction on the characteristics of humic substances in Brazilian soils

An investigation was made of the influence of alkaline extraction on the characteristics of humic substances extracted from Brazilian soil samples. Humic substances (HS) from seven different soils samples collected in Brazil were extracted using the procedure recommended by the International Humic Substances Society (IHSS). Soils, HS and humins were characterized by thermogravimetry and differential thermal analysis. About 8 mg of each material (soil, HS and humin) were placed in a platinum crucible and heated continuously from 20 to 750 degrees C at a heating rate of 10 degrees C min(-1) in an atmosphere of synthetic air (100 ml min(-1)). A thermal analysis revealed a difference between the content and structural characteristics of organic matter present in HS and humin fractions in relation to their soils. The results indicated that alkaline extraction alters the characteristics of humic substances during the extraction process, underlining the importance of developing methodologies and analytical procedures that allow organic matter in soils to be studied without extracting it.

Evaluation of pH and Calcium Ion Release of Calcium Hydroxide Pastes Containing Different Substances

Introduction: The objective of this study was to evaluate the pH and calcium ion release of calcium hydroxide pastes associated with different substances. Methods: Forty acrylic teeth with simulated root canals were divided into 4 groups according to the substance associated to the calcium hydroxide paste: chlorhexidine (CHX) in 2 formulations (1% solution and 2% gel), Casearia sylvestris Sw extract, and propylene glycol (control). The teeth with pastes and sealed coronal accesses were immersed in 10 mL deionized water. After 10 minutes, 24 hours, 48 hours, and 7, 15, and 30 days, the teeth were removed to another container, and the liquid was analyzed. Calcium ion release was measured by atomic absorption spectrophotometry, and pH readings were made with a pH meter. Data were analyzed statistically by analysis of variance and Tukey test (alpha = 0.05). Results: Calcium analysis revealed significant differences (P < .05) for 1% CHX solution and 2% CHX gel at 10 minutes. After 24 hours, 2% CHX gel x Control and 2% CHX gel x 1% CHX solution differed significantly (P < .05). After 48 hours, there were significant differences (P < .05) for 2% CHX gel x Control and Extract x Control. No differences (P > .05) were observed among groups in the other periods. Regarding the pH, there were significant differences (P < .05) for 2% CHX gel x Control and 2% CHX gel x 1% CHX solution after 48 hours and for 2% CHX gel x Control after 15 days. In the other periods, no differences (P > .05) were observed among groups. Conclusions: All pastes behaved similarly in terms of pH and calcium ion release in the studied periods.
