The effect of in utero protein malnutrition and subsequent renutrition on rat saliva and some salivary enzymes.
نویسنده
چکیده
1. Rat pups developed chronic protein insufficiency resulting from malnutrition diet in utero while their dams received 40 g protein/kg diet. 2. Before weaning they were found to have decreased salivary amylase (EC 3.2.1.1) and aminopeptidase activities. 3. A complete diet (250 g protein/kg) rapidly restored salivary amylase activity before weight normalization. However, renourished pups (malnourished pups given 250 g protein/kg for 14 d) still had increased numbers of Streptococcus multans in their plaque.

ABSTRACTIntroduction: Previous investigations have shown that protein malnutrition can alters the structure and function of some areas of hippocampal formation. We investigated the effect of protein malnutrition on amygdaloid projections to the CA1 hippocampal area. In this study we investigated level and pattern of distribution of efferent projections from amygdala to hippocampus in the rat by...
