The rats were given the synthetic diet of several kinds of carbohydrate instead of starch, such as sucrose, maltose, glucose, fructose, sorbose, xylose, lactose or mannose, whichwasc omposed of casein 20%, starch 68%, salt mixture 4%, soy-bean oil 5.5% and cod liveroil2.5%, and water-soluble vitamins were given orally in sufficie nt daily doses. The following was the result.
(I) Due to hydrolysis of the digestive enzyme, carbohydrates (sucrose, maltose and starch) changed into glucose and fructose, enabling the intestinal canal to absorb them And the following is obtained on the above carbohydrates.
Development and food intake of the rats were very good.
Blood sugar level, serum protein contents and its electroph oretic pattern and hemoglobinv alue were normal.
(II) On the monosaccharide (sorbose and xylose), which is found in nature only in very small quantity as such, the quantity absorbed fro m daily food is very little. Thenoticeable findings were observed.
a) Development and appetite of the rats were disturbed.
b) The rats looked healthy but died suddenly in a few days. Before their deaths, thebl ood sugar level fell to about 50mg%.
c) Serum protein contents, hemoglobin value and red blood cell count showed an increase The authors believe that these increases are due to the concentrationofblood.
(III) On the lactose and mannose, values between (I) and (II) were observed About half of the rats died after a few days in about two weeks, and on the rats that were alive, centred around the caecum, their ileum and colon were very much enlarged.
