Abstract
A number of regulatory or modulating influences have been proposed in the growth of the small and large intestine during the developmental and postnatal periods. These factors include dietary components, hormonal substances (most notably, glucocorticoids), and microbial flora (Johnson, 1981). According to Buts and de Meyer (1981), the mucosal mass of duodenal, jejunal, and ileal segments in rats increases during weaning (15–30 days postbirth) and at 40 days of age was similar to values in adult animals. It was concluded that the mucosal hyperplasia that occurs in the rat small intestine at weaning develops equally in proximal to distal segments of the bowel. In contrast to the small intestine, there is evidence that growth, differentiation, and enzymatic and absorptive characteristics of neonate rat colon undergo adaptation during the first 2 weeks of postnatal life (Helander 1973, 1975; Buts et al., 1983).
