Perfil do risco de óbito de crianças menores de um ano residentes em localidade do Estado de São Paulo, Brasil, 1987

Estudou-se a mortalidade de crianças menores de um ano de idade residentes no Município de Botucatu, SP (Brasil), em 1987. Tentando estabelecer o perfil de risco desses óbitos, tendo como seu principal responsável a desigualdade social, calculou-se o risco adicional (RA) em função de algumas variáveis usando a metodologia de estudos de caso-controle. O resultado obtido foi um RA de óbito de 15,58 para gestação pré-termo, 11,63 para o baixo peso ao nascer, 8,50 para inexistência de água intradomiciliar e 4,04 para escolaridade materna insuficiente. Verificou-se existir importante desigualdade entre as famílias das crianças que morreram e as das que sobreviveram, sugerindo que a melhor estratégia para enfrentar o excesso de mortalidade infantil residiria na melhoria sócio-econômica, isto é, todas as famílias deveriam ter a mesma capacidade de consumir os bens e serviços em igual quantidade e qualidade.

Reproductive Strategies of Brazilian Lizards of the Genus Tropidurus Rodrigues, 1987 (Squamata, Tropiduridae) in the Temporal and Spatial

Reproductive strategy is the set of adaptations that promote the most efficient way that the species will survive under the particular conditions of a determined environment. Understanding these adaptations is important and can help pinpoint populations indicator of environmental changes. Spermatogenesis is a measurable biological process of these adaptations in spatial and temporal scales. We analyzed the morphology of the testes and oviducts of the lizard species that comprise the genus Tropidurus, taking into account the geographical distribution and sympatric relations. For the analysis and the testes were removed from the middle part of the oviducts from Tropidurus etheridge, T oreadicus, T itambere, T spinulosus and T Guarani species, collected in different places in the Mato Grosso state, Brazil. The reproductive period is synchronous for males and females and occurs in September, October and November. Reproductive males were characterized. In the testes are seminiferous tubules with germ cells at different stages of spermatogenesis, with a high epithelium, at present light, free spermatozoa in the lumen and reduction of interstitial tissue. For females, the reproduction peak occurs when the oviduct epithelium is high with secretions and basal nucleus. These months are characterized in the sampled areas over a period of heavy rain and high temperatures. The decline of reproductive period was observed in both sexes, between April and August. Low reproduction in males is characterized by ample light, absence of sperm, only germ cells in the early stages of spermatogenesis are observed (a few spermatogonia and spermatocytes) and interstitial tissue wide. In females, the period of reproductive decline is marked by the absence of unicellular glands in the oviduct epithelium, with higher affinity with the dye. This period corresponds to low rainfall periods and lower temperatures. We propose an analysis of zoological samples; this is a proposal to facilitate the work of many researchers through access to the species, especially rare species.
