IntroduçãoApesar dos avanços científicos e tecnológicos na vigência do terceiro milênio, a rotura prematura das membranas (RPM) continua sendo um desafio para o obstetra e certamente o será para aqueles que irão militar na especialidade no sé-culo XXI.As principais repercussões maternas incluem aumento na taxa de cesárea, corioamnionite clínica e infecção pós-parto, ao passo que o risco perinatal inclui, entre outros, prematuridade, infecção, sepse neonatal e óbito fetal e neonatal [1][2][3][4][5] . Com a finalidade de obter maturidade pulmonar fetal a conduta expectante, com ou sem a

The effects of high and low-protein diets on the structure of the jejunal mucosa were studied in Schistosoma mansoni infected mice (morphology and histomorphometry). Weaning male albino mice were infected with 80 cercariae, fed with high (20%) or low-protein (5%) diets and compared to uninfected controls under the same conditions. Mice were sacrificed 12 weeks after infection. Animals submitted to a low-protein diet showed lower weight curves, mainly when infected. In the jejunal mucosa, finger-like villi were the predominant pattern among uninfected high-protein fed animals, while the infected ones showed leaf-shaped and flattened villi in most cases. Undernourished infected mice had 65.7% leaf-shaped villi. A significant increase in the number of goblet cells was seen in infected mice. A decrease in the number of absorptive cells was detected in undernourished mice, particularly in infected ones.
