INTRODUCTION: Basketball is characterized with high injury rate. In the literature it's not defined whether or not there are differences between the sexes. OBJECTIVE: Characterize and analyze the incidence of athletic injuries in basketball players, comparing the sexes. MATERIALS AND METHODS: Fifteen under-23 category athletes of each sex were interviewed with the reported morbidity inquire. RESULTS: The age of the female and male teams, in average, was 18 ± 0.65 and 18.20 ± 1.57 years respectively. The male team had more injuries than the female one (respectively 2.6 ± 1.45 against 1.2 ± 1.18, p < 0.05). The joint damage was the most common injury in the male team, representing 58.97%, and the second most common in the female team (33.33%). The lower limbs were the most common injured sites (80.95% in the female and 69.23% in the male). The most frequent injury mechanism in the male team was the landing (43.59%), and in the female was the vertical jump (28.57%). In both teams the most injuries occurred during the training (61.9% in the female and 71.8% in the male). The absence was necessary in 47.62% (female) and 56.41% (male). Great part of the athletes didn't received any treatment (61.9% and 51.28% in the female and male team respectively). The return to the activities was mostly symptomatic, in both female and male team (85.71% and 84.62% respectively). CONCLUSION: The incidence of injuries in basketball is higher in the lower limbs. The male team is more likely to suffer injuries, and the main injury mechanisms were different between male and female team.

The aim of this research was to estimate the skeletal growth and development by observingradiographically the morphological changes of the first, second and third cervical vertebrae, according to the method proposed by Hassel &Farman32 (1995) in patients who were going through the outbreak of pubertal growth. The radiographic inspection of the cervical vertebrae was performed by means of cephalometric radiographs and the outbreak of pubertal growth was identified through the events of ossification of the hand and wrist. For that purpose, we selected thecephalometric radiographs and hand•wrist radiographs of 110 Brazilianleukoderms, male and female,with chronological age ranging from 8 to 14,6 years old for the girls and from 9,5 to 15,4 years old for the boys.The results showed that there was a statistically significant correlation between the maturation indicators of the cervical vertebrae and the patients who were going through the outbreak of pubertal growth. The conclusion was that the radiographic evalution of the changes of the cervical vertebrae, in the cephalometric radiographs, is an alternative parameter, which is reliable and practical in the skeletal evalution, and the it completes the range of information that must be obtained from the patient under orthodontic treatment and that it can, circumstantially, replace other methods of evalution

The text aims to refl ect about masculinity and femininity in children’s education, an almost entirely feminine environment, bringing fi ndings of a study that investigated the social relations of gender in this level of teaching in a school where a man worked as a teacher. Data was composed by observations of pedagogical practices of a woman teacher and a man teacher of Early Childhood Education. After that, those teachers, the pedagogical coordinator, the headmaster and a nursery worker were interviewed. Based on theoretical contributions about culture and gender, the paper shows that the masculine and the feminine identities and social roles for both sexes, historically, are human constructions that can be modifi ed, especially at school.

A fluoxetina, pertencente à classe dos inibidores da recaptação seletiva de serotonina, é um dos antidepressivos mais amplamente prescritos para o tratamento da depressão e de transtornos da ansiedade, como o transtorno obsessivo compulsivo. Considerando que, dentre os efeitos colaterais causados pela fluoxetina, têm sido relatados distúrbios na função sexual masculina, foi proposto avaliar a ação deste fármaco sobre a integridade morfológica dos túbulos seminíferos. Foram utilizados 16 ratos adultos, distribuídos em 2 grupos: grupo fluoxetina (GF) e grupo controle (GC). Os animais do GF receberam injeções intraperitoneais de fluoxetina (20mg/Kg) e os animais do GC receberam água destilada. O tratamento se estendeu por 11 dias consecutivos e, ao final do tratamento, foram obtidos os pesos corpóreo e testicular dos animais. Os testículos foram fixados e processados para inclusão em historesina e parafina. Nos cortes de historesina, as frequências de túbulos de acordo com o estágio do ciclo do epitélio seminífero e de túbulos seminíferos contendo células descamadas preenchendo a luz tubular foram obtidas, bem como os seguintes parâmetros morfométricos: área tubular total, área da luz tubular e área do epitélio seminífero. Os cortes em parafina foram submetidos ao método do TUNEL para detecção de morte celular. Os níveis séricos de testosterona também foram avaliados. Os resultados foram submetidos à análise estatística para avaliação das diferenças entre os grupos. O tratamento com fluoxetina causou redução significante do peso corpóreo dos animais e redução, embora não significante, do peso testicular absoluto. Além disso, uma redução significante nos níveis séricos de testosterona foi observada nos animais do GF. Os túbulos seminíferos apresentaram contorno irregular, depleção celular e intensa desorganização epitelial, bem como a presença de vacúolos e ...
