qod 4 times. Experimental results:(1) Leucocyte counts and myeloid cell counts of the toxic group are lower than those of the control group (P<0.01)

myeloid cell chromosomal aberration (MCCA)percentages are higher than “those of (P< 0.01) and vacuoles are found in polymorphonuclear cells.(2) The results of the preventing groups are all in normal values.It suggests that acupuncture or moxibustion is well effective in preventing mice benzene poisoning.
