摘要
Este artigo é resultado de uma pesquisa bibliográfica sobre a produção nacional a respeito do encaminhamento de crianças em processo de escolarização a profissionais de saúde, como expressão do processo de medicalização da educação. Realizou-se levantamento bibliográfico na base de dados Biblioteca Virtual em Saúde-Psicologia Brasil/BVS-Psi com os termos: medicalização, medicalização da educação, professores e encaminhamentos, queixa escolar, medicalização na rede pública, queixa escolar e medicalização e medicalização da queixa escolar. Selecionaram-se os textos que apresentavam uma perspectiva crítica a respeito dos processos de medicalização da/na educação. Os resultados desta pesquisa indicam que os encaminhamentos são realizados partindo-se de uma concepção de que as dificuldades apresentadas pelas crianças no processo de escolarização são de caráter individual e, dessa forma, passíveis de resolução no campo da saúde. Entretanto, há uma marcante falta de comunicação entre esses serviços e a escola, o que contribui para o recurso ao uso de drogas psicotrópicas como uma das principais medidas para intervir junto às queixas escolares, em detrimento do recurso a novas práticas institucionais da escola.
This article is the result of a bibliographical research on the Brazilian bibliographical production regarding the referral of children in schooling process to health professionals, as an expression of the medicalization process of education. A bibliographical survey was carried out in the database of the Virtual Library of Health/ Psychology Brazil/BVS-Psi under the terms: medicalization, medicalization of education, teachers and referrals, School complaint and medicalization and medicalization of the school complaint. The researchers selected the texts that presented a critical perspective regarding the medicalization processes of the education. The results indicate that the production of referrals rely on a conception that the difficulties presented by the children in the schooling process, as the school identifies them, are individual in nature and, therefore, can be resolved in the health field. However, there is a lack of communication between these services and the school, which contributes to the use of psychotropic drugs as one of the main measures to intervene with school complaints, rather than making new school practices in order to enhance the schooling process.

Se realizó una revisión de la literatura en la base de datos Biblioteca Virtual en Salud-Psicología Brasil / BVS-Psi con los términos: medicalización, medicalización de la educación, profesores y derivaciones, queja escolar, medicalización en la red pública, Queja escolar y medicalización y medicalización de la queja escolar . Se seleccionaron los textos que presentaban una perspectiva crítica acerca de los procesos de medicalización de la educación. Los resultados de esta investigación indican que las derivaciones se realizan partiendo de una concepción de que las dificultades presentadas por los niños en el proceso de escolarización son de carácter individual y de esa forma susceptibles de resolución en el campo de la salud. Sin embargo, hay una marcada falta de comunicación entre estos servicios y la escuela, lo que contribuye al uso de drogas psicotrópicas como una de las principales medidas para intervenir junto a las quejas escolares, en detrimento del recurso a nuevas prácticas institucionales de la escuela.

ABSTRACT In this study, the effect of thymoquinone (TQ) on propylthiouracil (PTU)-induced memory impairment was investigated in juvenile rats. The rats were grouped into control, Hypo, Hypo-TQ5 and Hypo-TQ10. Propylthiouracil increased latency time in the Morris water maze test and decreased delay in entering the dark compartment in the passive avoidance test. Both 5 mg/kg and 10 mg/kg doses of TQ decreased latency time in the Morris water maze test and increased delay in entering the dark compartment in a passive avoidance test. The PTU also increased malondialdehyde and nitric oxide metabolites in the brain while reduced the thiol content and superoxide dismutase and catalase activities and serum T4 level. Both doses of TQ decreased malondialdehyde and nitric oxide metabolites in the brain while enhanced the thiol content and superoxide dismutase and catalase activities and serum T4 level. The results of the present study showed that TQ protected against PTU-induced memory impairments in rats.
RESUMO Neste estudo, foi investigado o efeito da timoquinona (TQ) contra deficiências de memória induzidas por propiltiouracilo (PTU) em ratos juvenis. Os ratos foram agrupados em grupos: controle, Hypo, Hypo-TQ5, e Hypo-TQ10. O PTU aumentou o tempo de latência no teste do labirinto aquático de Morris (MWM) e diminuiu o atraso para entrar no compartimento escuro no teste de evasão passiva (PA). Ambas as doses de TQ diminuíram o tempo de latência no teste de MWM e aumentaram o atraso para entrar no compartimento escuro no teste de PA. O PTU também aumentou os metabolitos de malondialdeído (MDA) e óxido nítrico (NO) no cérebro, enquanto reduziu o teor de tiol e as atividades de superóxido dismutasa (SOD) e catalasa (CAT) e o nível sérico de T4. Ambas as doses de TQ diminuíram os metabolitos de MDA e de NO no cérebro, aumentaram o conteúdo de tiol e as atividades de SOD e CAT e o nível de T4 no soro. Os resultados do presente estudo mostraram que a TQ protegeu contra deficiências de memória induzidas por PTU em ratos.

Reduction in cerebral blood flow following cereblal ischemia cause the production of oxygen free radicals and finally leads to brain tissue destruction. Pyramidal cells of the CA1 region of hippocampus are highly sensitive to hypoxic condition. This study was done to determine the effect of human chorionic gonadotropin [hCG] and vitamine E on cellular density of CA1 hippocampal area, learning ability and memory, following ischemia - reperfusion injury in mice. This experimental study was done on 40 male mice in 5 groups as follow: sham control, ischemia, hCG treated, vitamine E treated and hCG + vitamine E treated groups. Single dose of vitamin E was injected intraperitonaly during the establishment of reperfusion and hCG was injected from 48h after ischemia for 5 days. Folowing the treatment period, mice brains were fixated by transcardial perfusion and stained by nissle method. The shuttle box was used to evaluate the learning memory. Co-administartion of vitamine E and hCG, significantly increased the cell numbers in hippocampus compared to the ischemic group [P<0.001]. Also learning and memory improved in treatment group in comparison with ischemia group [P<0.05]. Co-administration of vitamin E and hCG improved ischemia-induced neurodegenration and memory impairment

The study was conducted on 64 CF strain albino rats, which were equally distributed into 8 evenly matched groups following a 2 x 2 x 2 factorial design, by varying three independent factors at two levels: nutrition--normal and undernutrition; environment--enrichment and impoverishment, and drug treatment--vehicle and pyritinol (100 mg/kg, ip). Prenatal undernutrition was induced by restricting the mother's food intake. The environmental enrichment/impoverishment and the vehicle/pyritinol treatments were given during the postweaning period of the pups. The rats were subjected to original and subsequent reversal brightness discrimination learning tests in a single unit T-maze at 8-9 weeks of age. Thereafter, the animals were tested for the passive avoidance learning. The results indicate that undernutrition caused significant original discrimination learning deficits whereas environmental deprivation attenuated both the original and reversal learning performance. Environmental impoverishment attenuated the retention of passive avoidance behaviour but undernutrition had no effect on this paradigm. Pyritinol treatment improved the learning and retention performance of normally reared rats and also attenuated the original and reversal learning deficits induced by parental undernutrition and postweaning environmental impoverishment. The results indicate that pyritinol may be useful in learning and memory deficits induced by malnutrition and environmental deprivation.

El Piracetam es un nootrópico de efecto positivo en la maduración de las funciones perceptuales; es capaz de mejorarla en la coordinación visomotora (ojo, mano). Mejora notoriamente la conducta social del niño con D.C.M. No favorece cambios en la inteligencia global (C. I.), pero sí puede mejorar y favorecer el desarrollo del C.I. ejecutivo. No hemos encontrado cambios en la capacidad de retención visual. Las evaluaciones clínico-neuropsicológicas confirmaron los hallazgos de los tests neuropsicológicos y nos dieron una visión más amplia de la maduración de otras funciones neurológicas con el uso del Piracetam; entre estos aspectos señalaremos: coordinación axial y segmentaria (equilibrio y marcha); praxias bucofaciales; funciones perceptuales; coordinaciones perceptivas motoras complejas; lenguaje expresivo y comprensivo; lectura, escritura y cálculo aritmético; conducta hiperactiva perceptivo-motora y otros síntomas menores, como enuresis, somnilóquias, sudores y así sucesivamente
