Biological effects of flammulina velutipes rich in RE on Chinese kunming mice

In this paper, effects of RE from different sources on the growth, development and endurance of Chinese kunming mice have been studied. The result indicates that the body and organ weights and endurance of the mice in group B(F. velutipes) are significantly increased over those in the control group (group E) after three weeks, and it also shows that the biological effects vary with the amount of RE in diet. Compared with group D(RE (NO3)(3)), group B has the same amount of RE in diet but the body and organ weights are much heavier, swimming time is increased by 28.6%, and the changes of brood sugar and serum lactic acid after swimming decrease notably. Thus, it can be found that F. velutipes rich in RE added in diet performs a positive function to promote the mouse growth, development and endurance, while the inorganic RE(NO3)(3) fails on it, even inhibits their growth.
