【Abstract】 Mice of Kunming strain were fed with Mortierella isabellina mycelium powder for 15 d by exposing to 60Co radiation. The white cell number, the mutation rate of chromosome and cell, the survival time of the animals, and the levels of LPO and SOD in animals’ serum were determined, respectively. The results showed that Mortierella isabellina mycelium powder had very strong positive effects on the radiation-resistant ability of mice: the number of white cell was higher, the informal rates of chromosome and cells were lower, the LPO level was lower, the SOD level was higher in the animals of experimental group than in those of control. The survival time of the experimental group was prolonged significantly after radiation. Tab 5, Ref 11更多还原
