Abstract
The excretion of the metabolic fecal fat and nitrogen was studied in the Japanese subjects with the following results (M±δ):
metabolic fecal fat=0.79±0.19g/day.
metabolic fecal nitrogen=0.76±0.22g/day.
The effect of cellulose on the excretion of metabolic fecal fat and nitrogen was studied in al-bino rats and human subjects. In the former' the effect was obscure, while to the latters were given protein-and fat-free diet containing 3% cellulose and the metabolic fecal fat and nitrogen were obtained as 0.98±0.19g/day and 1.11±0.26g/day, respectively.
Both values were apparently greater than those obtained after the administration of cellulose-free diet, but the difference was not statistically significant.
