RESUMO
A insatisfação corporal, preditora de transtornos alimentares, é a desaprovação pelo indivíduo de sua própria aparência física. Este estudo examinou esta variável em 303 estudantes, de 6 a 14 anos idade, do Ensino Fundamental de Porto Alegre - RS. Cada participante indicou a silhueta mais parecida com a de seu corpo e a mais desejada, numa Escala de Silhuetas. Tam-bém foi calculado o Índice de Massa Corporal para cada indivíduo. Como insatisfação corpo-ral foram consideradas as diferenças entre os escores das silhuetas autopercebidas e desejadas. A insatisfação corporal apareceu a partir de 10 anos para meninas e foram encontradas dife-renças sexuais na forma de experimentar esse sentimento. Possivelmente, maturação física e fatores psicossociais explicam esses achados.
The body dissatisfaction, a predictor of eating disorders, is defined as the disapproval of the individual by their physical appearance. This study investigates this variable in 303 students from six to 14 years old of elementary school in Porto Alegre / RS. Each participant indicated the closest silhouette with your body and the most desired in Silhouette Scale, was also calcu-lated the Body Mass Index for each. As body dissatisfaction were considered discrepancies between the scores of autopercebidas and desired silhouettes. Body dissatisfaction occurred from 10 years for girls and sex differences were found in the form of experience that feeling. Possibly physical maturation and psychosocial factors explain these findings.

Este estudio investigó esta variable en 303 estudiantes de seis a 14 años de edad de la escuela primaria en Porto Alegre / RS. Cada participante indicó la silueta más cercana con su cuerpo y la más deseada en la escala de silue-tas, también se calculó el Índice de Masa Corporal de cada individuo. Las discrepancias entre las puntuaciones de las siluetas auto percibida y siluetas deseadas se consideró como una me-dida de la insatisfacción corporal. La insatisfacción corporal surgió a partir de 10 años para las niñas y se encontraron diferencias de sexo en la forma de experimentarla. Posiblemente la maduración física y los factores psicosociales explican estos resultados.

BACKGROUND/AIMS: Host factors that may influence progression of hepatitis C infection to chronic hepatitis include T-cell responses and iron accumulation. We evaluated the hepatic expression of immunological markers relevant for a cytotoxic response in relation to viral and HFE genotype. METHODS: Frozen liver biopsies were obtained at diagnosis from 28 HFE genotyped patients. Sections stained for CD8, MHC-I, beta(2)m, HFE and CD68 were analyzed blind by morphometry. Response to therapy was available in 12 cases. RESULTS: A negative correlation was found between the number of CD8(+) cells and fibrosis. CD8(+) cells localized as clusters in portal tracts and sinusoids and were seen interacting with MHC-I positive lining cells. MHC-I and beta(2)m were expressed mainly in the endothelial and Kupffer cells. HFE was expressed in most, but not all, round and dendritic CD68(+) cells. Patients with virus genotype 3a had higher hepatic MHC-I and HFE expression, and a better-sustained response to IFN therapy than other patients. CONCLUSIONS: In chronic hepatitis C virus infection MHC-I expression in the liver seems to relate to viral-genotype. In addition, the expression of MHC-I molecules by Kupffer cells places them as probable important players in the host response to HCV.
