(3) CCK-induced translocation of albumin, IgC and IgA is prevented by F. children, with a higher proportion of saturated fatty acids and a lower proportion of polyunsaturated essential fatty acids in the Pakistanis. These findings are consistent with the view that a relatively high intake of polyunsaturated fatty acids improves fluid and electrolyte absorption and protects against secretory diarrhoea in humans as well as in rats. They may have imnortant implications for the rehabilitation of children with diarrhoeal illnesses and malnutrition in developing countries.
