Peptide growth factors and preimplantation development.

This paper examines some of the problems and questions that must be considered in relation to research on the role of growth factors in preimplantation embryos. It reviews and summarizes the large body of work on gene expression of growth factor receptors and ligands in preimplantation embryos and in oviduct and uterine tissue. It also reviews the literature on the effects of gene knockout in preimplantation embryos and concludes with a review of work on the effects of growth factors on cultured embryos.

Dental health of Louisiana residents based on the ten-state nutrition survey.

The dental health status of 4,006 residents of Louisiana was analyzed, based on data in the 1968-70 Ten-State Nutrition Survey funded by the U.S. Government. These data were based on examinations of census districts in which the average per capita income was in the lowest quartile for the nation. A considerable variation in the prevalence of dental diseases was found among the Louisiana residents according to age. The females examined had a slightly higher DMF (decayed, missing, and filled permanent teeth) score, a lower OHI (oral hygiene index) score, and a slightly lower PI (periodontal index) score than did the males. The dental caries attack rate did not vary much by race, but the whites examined had received a much greater amount of dental care than had their black counterparts. The OHI scores of the blacks were higher than those for the whites in both the debris and calculus components. The PI scores were higher for the blacks than for the whites. More white persons than blacks were edentulous; this result, however, tends to confirm the observation of increased dental care in white persons. The percentages of persons with periodontal disease and periodontal pockets were considerably higher among persons with incomes below the poverty level, and a greater percentage of blacks had incomes below that level. The data thus apparently indicate that the major determinants of dental health status in Lousiana are age and level of income; race appears to be the major determinant of the amount of dental care received.
