Avaliação Histológica e histomorfométrica do reparo ósseo em tíbias osteotomizadas de ratos (rattus novergicus albinus), submetidos a tratamento com ultrassom, frente à presença e ausência de carga

The response of bone metabolism is directly related to hormonal factors and mechanical stimuli that the bone is exposed. The ultrasonic energy on bone healing have been shown to be crucial for the stimulation and improvement in quality of newly formed tissue. The aim of this study was to analyze the action of low intensity ultrasound on bone healing of tibial osteotomy in rats subjected to tail suspension, through histological analysis and histomorphometry. Eighteen Rattus norvegicus albinos, Wistar, adults were divided into three groups, arranged as follows: G1 (n = 6), who remained free for a period of 15 days, G2 (n = 5), suspended by the tail for a period of 15 days and G3 (n = 7), suspended by the tail for a period of 36 days. In all three groups, both tibias were subjected to mono-cortical bone injury 4X2 mm in the medial region of the diaphysis, and the left limb was used as control and the right limb undergoing treatment with ultrasound (U.S.). The right tibia was treated with pulsed ultrasound at a frequency of 1.5 MHz, duty cycle 1:4, 30mW/cm2, for 12 sessions of 20 minutes each. Samples of tibia were subjected to histological analysis, blindly, with light microscopy and histomorphometric analysis by specific software Image-Pro 6.1. The average percentage of new bone formation were subjected to analysis of variance in subdivided parcels and multiple comparison test "Student-Newman-Keuls (SNK), with a significance level of 5%. The average values and standard deviations of the percentage of newly formed bone for the groups showed the least amount of bone repair G1t (13.62% ± 4.88%) - G1c (8.68% ± 4.16%) compared G2t groups (27.17% ± 11.36%) - G2c (10.10% ± 7.90%) and G3t (23.19% ± 5.61%) - G3c (15.74% ± 7 08%). However, the mean values and standard deviations of the percentage of newly formed bone repair in the tibia treated G2t and G3t were significantly higher when compared to the repair of tibia in the control group (G2c and G3c). Consequently, we conclude that ultrasound has helped to accelerate bone repair in both the presence and absence of cargo.

A gestão democrática em uma escola de educação de jovens e adultos

This paper addresses the democratic school management within the school organizations. For this, initially made brief remarks on labor relations, the development of administrative and organizational theories. Later, we reflect on how the se labor relations are organized in the educational environment and what education theoretical contributions to the development of school management in Brazil. Therefore, we discuss the Brazilian educational policies that postulate and legitimate democratic school management. Studies of everyday guided the theoretical basis of this work, we wonder what school subject dealing with the discourse of democratic and participative management. Forward the hypothesis that participatory management should be a prominent space in schools, the aim of this study was to investigate the school management of a municipal school of Youth and Adult Education, which brings in your organization pedagogical foundation and educational principles espoused by Paul Freire. The specific objectives of the study are: a) to investigate and describe how is the organization's management of school youth and adults; b) understand the role of managers; c) check how teachers and administrators understand the process of managing this school. From a methodological point of view the daily life of the studies led this work to procedures and qualitative analysis of ethnographic referring to practices that have occurred in adult education school along with the theoretical foundation. Participated in this research members of the school management group and four teachers of Youth and Adult Education rooms. The results obtained showed that dialogue and democracy go together, that the school is an organization with different world views, which need to be primarily present in the identity of the schools. It was also possible to find different democratic practices in the management and organization of the Educational Center that make school subjects become...
