RESUMEN
Sabe-se que o sedentarismo, associado a uma dieta nao balanceada tem grande importancia para o desenvolvimento de doencas cronico degenerativas. Por outro lado, o exercicio fisico tem sido um meio utilizado para o controle dessas doencas. Entretanto, pouco foi relatado sobre efeitos do exercicio de final de semana nocontrole das dislipidemias. Assim, o objetivo deste estudo foi observar respostas adaptativas ao exercicio de final de semana sobre o metabolismo das lipoproteinas em ratos machos alimentados com dieta hiperlipidica. Foram divididos em grupos 96 ratos machos adultos: dieta normocalorica (N) e hipercalorica (H), sedentario (S), treinado continuo (TC) e treinado de fim de semana (TFS), 5 e 2 sessoes semanais/90minutos/dia, respectivamente, por natacao. Durante todo o periodo experimental foram controlados: o peso e o consumo alimentar em gramas. Foram coletados, pesados e congelados o plasma (P), os tecidos adiposos barncos retropeitoneal (RET) e epididimal (EPI), tecido adiposo marron (TAM), musculo gastrocnemio (GAST), figado (FIG) e coracao (COR), para posteriores analises. Foram considerados significativos os valores de p<-0,05 a partir da analise de variancia `Anova Tree Way`. O treinamento de final de semana promoveu diminuicao significativa nos triglicerideos plasmaticos em animais hipercaloricos (SH 180,7+-13,9 vs TFSH97,2+-8,3). Os dois tipos de treinamento foram importantes no controle das dislipidemias em ratos alimentados com dieta hipercalorica, sendo observado aumento na concentracao de HDL colesterol em relacao aos respectivos animais sedentarios (SH 26,5+-2,0 vs TCH 35,7+-6,2 e TFSH 37,1+-1,2)

The construction of the Diama dam on the Senegal river, the Manantali dam on the Bafing river, Mali and the ensuing ecological changes have led to a massive outbreak of Schistosoma mansoni in Northern Senegal, associated with high intensity of infections, due to intense transmission, and the creation of new foci of S. haematobium. Data on the vectorial capacity of Biomphalaria pfeifferi from Ndombo, near Richard Toll, Senegal are presented with sympatric and allopatric (Cameroon) S. mansoni. Comparisons are made on infectivity, cercarial production, chronobiology of cercarial emergence and longevity of infected snails. Recent data on the intermediate host specificity of different isolates of S. haematobium from the Lower and Middle Valley of the Senegal river basin (SRB) demonstrate the existence of at least two strains of S. haematobium. The role of Bulinus truncatus in the transmission of S. haematobium in the Lower and Middle Valleys of the SRB is reviewed. Both S. haematobium and S. mansoni are transmitted in the same foci in some areas of the SRB.
