Medicina preventiva e assistência médica na previdência social

Foi apresentado um plano de aplicação de critérios de medicina preventiva à assistência ambulatorial oferecida pelo Instituto Nacional de Previdência Social a seus segurados em São Paulo. O plano, a ser implantado já no 2.° semestre de 1973, compreenderá 4 programas básicos: de imunização, de combate à tuberculose, de assistência pré-natal e de assistência à infância. Cada um desses programas é apresentado em pormenores, compreendendo objetivos principais, prioridades e metas operacionais.A plan of application of preventive medicine criteria to the outpatient clinics oferred by the National Institut of Social Welfare to their members in São Paulo is exposed.

Transposable elements P and gypsy in natural populations of Drosophila willistoni

The presence and integrity of the P transposon and the gypsy retrotransposon in the genome of 18 samples of natural Drosophila willistoni populations collected from a large area of South America were Southern blot screened using Drosophila melanogaster probes. The aim of this screening was provide further knowledge-base on the geographical distribution of D. willistoni and to carry out an inter-population analysis of the P and gypsy elements present in the genomes of the populations analyzed. The fragment patterns obtained indicate that both the P and gypsy elements are ancient in the D. willistoni genome, but whereas the gypsy retroelement appears to be invariable and stable the P element varies between populations and appears to still have some capacity for mobilization
