RESUMEN
In order to study the new function of riboflavin, the experiments of ri-boflavin on the prevention of teratogenesis were conducted. The experimental rats were divided into four groups A,B,C,D. A served as a control group, B,C,D, were given 50?g, 250ng and 1000?g of riboflavin respectively for one week intragastrically prior to the study. After pregnancy, all rats including controls were given teratogenic pesticide Dikushuang 0.75mg/kgbw for contaminaton intragastrically, riboflavin being given continually as before, to observe the effects on body weight growth and hemoglobin level of pregnant rats. The following parameters were measured: the reproduction of pregnant rats, the development of fetus and the teratogenic activity of fetus after animals were killed. The experimental results showed that the average body weight gain in the each dose groups of riboflavin were higher than the control group, but the difference was not significant. The hemoglobin levels at various experimental times were less significant among the groups.The rates of the resorption and the living fetus in 250?g and 1000?g groups were significantly lower than the control (P
RESUMEN
The purpose of this study is to assess the nutritional value and biological effect of Collybia Velutipes. The results were as follows: (1) 10% Collybia Velutipes extract contains 19210mg/L of total amino acid. It is more than the content in the equal amount of mushrooms. (2) The kindergarten children were fed with Collybia Velutipes product for 7 weeks. It was found that the height and the circumference of the mid-upper arm in the children were significantly higher than the control. (3) Weanling male and female rats of wistar strain were divided into two groups ana led the following diets: group l(control), Collybia Velutipes (CV) free diet; group 2(subject), diet containing 25% CV product which contains 2.5% dried CV. The rats were fed the diet ad libitum for 6 weeks. At the end of the experiment, we found that the food effect (FE) of the subject group was significantly higher than the control (P
