Figure 1 A: The number of goblet cells and the morphology of jejunal villi in the postnatal 3^rd month × 100. B: The number of goblet cells in rat jejunal villi in the postnatal 3^rd month × 100. C: The number of goblet cells and the morphology of jejunal villi in the postnatal 12^th month × 100. D: There were few or no goblet cells in the jejunal glands of newborn rats × 400; E: The number of goblet cells in rat jejunal gland was much higher in the postnatal 12^th month than in any other month × 400. F: The jejunal villi of newborn rats displayed ateliosis and were very small × 200.
