The interactive effects of lima bean trypsin inhibitor (TI), hemagglutinin (Hgg) and cyanide (CN) when fed at the same degree of activity as found in the raw lima bean (RLB) were assessed in weanling rats using hepatic glutamate dehydrogenase (GLDH), isocitrate dehydrogenase (ICDH), ornithine carbamoyltransferase (OCT) and intestinal disaccharidases activities as the response criteria. Whereas RLB significantly (P less than 0.05) increased hepatic GLDH and decreased ICDH activities respectively, dietary CN, TI and Hgg whether acting individually or jointly had no significant influence on GLDH. Only the CN-containing diets significantly (P less than 0.05) elevated ICDH activity when compared with the control. Raw lima bean significantly (P less than 0.05) depressed OCT activity while neither the individual nor collective effects of these factors were significant. Dietary CN + TI + Hgg interaction depressed maltase activity to approximately the same extent as RLB in all the intestinal regions. These factors had neither individual nor collective effects on sucrase in the small intestine. Lactase activity in the small intestine was influenced only by the RLB diet, while CN + Hgg, and CN + TI + Hgg dietary combinations induced significant (P less than 0.05) elevations in the activities of cellobiase when compared with the control. Although synergism of action is indicated in a number of instances, it is suggested that these factors may need to combine with others within the bean, perhaps synergistically, to elicit comparable anti-nutritional influences as the RLB.

The aim of this study was to evaluate the effect of two sources of dietary nitrogen (isolated whey protein and hydrolyzed whey protein) on the intestinal repair of malnourished rats at weaning. The malnutrition was achieved by a 3 days' starvation period. Normally fed male Wistar rats were used as controls. Intestinal repair was studied after a refeeding period of 4 days. The parameters studied included nitrogen balance, lactase, sucrase, isomaltase, and maltase activities of the jejunum; liver acetylcholinesterase and glutamate dehydrogenase activities; and the serum amino acid profile. In addition, tests of intestinal permeability to macromolecules were performed by measurement of ovalbumin and beta-lactoglobulin in serum. Both diets of led to the recovery of the severely starved rats, in terms of the values of all the parameters evaluated. The serum beta-lactoglobulin was the only exception, because its concentration was significantly lower in the normally fed animals. This study suggests that the intestinal mucosal barrier is not completely repaired, even after a 4-day refeeding period, to the point of being suitable to accept an increase in the uptake of antigens.
