Cellular composition of the bone marrow 24 h (A) and 48 h (B) following rmLF treatment. Mice were given rmLF and mTF (100 μg). The results are presented as the mean value of five mice per group. Statistics: (A) Neutrophils: control versus mTF, NS (P=0.89); control versus rmLF, NS (P=0.06); mTF versus rmLF, P<0.01; bands: control versus mTF, NS (P=0.99); control versus rmLF, NS (P=0.61); mTF versus rmLF, NS (P=0.45); metamyelocytes: control versus mTF, NS (P=0.97); control versus rmLF, NS (P=0.11); mTF versus rmLF, P<0.05; myelocytes: control versus mTF, NS (P=0.19); control versus rmLF, NS (P=0.44); mTF versus rmLF, NS (P=0.98); other: control versus mTF, NS (P=0.38); control versus rmLF, P<0.02; mTF versus rmLF, P<0.0005. (B) Neutrophils: control versus rmLF, P<0.001; bands: control versus rmLF, P<0.02; metamyelocytes: control versus rmLF, NS (P=0.21); myelocytes: control versus rmLF, NS (P=0.48); others: control versus rmLF, P<0.0002. Ne, neutrophils; B, bands; Me, metamyelocytes; My, myelocytes; O, other.
