Growth, digestibility, and enzyme activities in the pancreas and intestines of guinea-pigs fed on raw and heated soya-bean flour.
The nutritional effects of giving raw (RSF) or heated (HSF) soya-bean flour to young guinea-pigs were investigated in trials 1 and 2, in which the levels of dietary protein were 120 and 190 g/kg diet respectively. The growth rate of animals fed on RSF was lower than that of those fed on HSF. Growth retardation of guinea-pigs fed on RSF was accompanied by a lower apparent digestibility of the pr...
متن کاملThe effect of long-term feeding of soya-bean flour diets on pancreatic growth in the rat.
1. Pancreatic growth was measured in rats by changes in pancreatic weight, nucleic acid content and protein content after feeding diets of heated soya-bean flour (HSF), raw soya-bean flour (RSF), 200 g raw soya-bean flour + 800 g heated soya-bean flour/kg (80 HSF) and 400 g raw soya-bean flour + 600 g heated soya-bean flour/kg (60 HSF) for periods up to 36 weeks. Control rats of comparable age ...
متن کاملFate of pancreatic nodules induced by raw soya flour in rats.
We have previously shown that rats fed raw soya flour (RSF) for more than four months develop hyperplastic foci of pancreatic acinar cells, which undergo malignant change if feeding RSF is continued throughout the life of the animals. The tendency to undergo malignant change is augmented by the additional use of a genotoxic carcinogen such as azaserine. The present study has sought to examine t...
متن کاملIntestinal free trypsin concentrations fall only transiently when rats are fed raw soya flour.
Raw soya flour (RSF) is thought to cause pancreatic hypertrophy in rats because trypsin inhibitor in the flour binds trypsin in the gut lumen and this lowering of free trypsin concentrations leads to the release of cholecystokinin (CCK). Intestinal enzyme concentrations were therefore studied in rats fed RSF for from one hour to 400 days to determine whether free trypsin concentrations were dep...
متن کاملThe Soya Bean and the New Soya Flour
The soya bean has been one of the staple foods of China and Japan for centuries; but it has never been consumed to any extent by other nations. Hitherto it has been grown chiefly in Manchuria, whence it is exported to Europe and America. The cost of production is low. In composition it is rich in fat and protein. In fact it resembles meat more in composition than other legumes or cereals do. It...
