Table II.  Effects of local administration of W₁₁-a₁₂ (10mg/wound) on the decrease of white blood cells (WBC) in peripheral blood and nucleated cell number in marrow in rats irradiated with 6 Gy total body irradiation.

Group	Percent of WBC (%)
	3h	6h	12h	24h	48h
SW	102 ± 32	102 ± 18	110 ± 41	126 ± 29	185 ± 49
6RW	203 ± 57^a	110 ± 45	54 ± 27 ^a	29 ± 22^b	11 ± 3^b
6RW+ W11-a12	189 ± 22^bc	98 ± 14^c	48 ± 22^ac	38 ± 14^bc	10 ± 1^bc
	Nucleated cell number (×10^6)
SW	6.8 ± 0.3	7.4 ± 0.3	7.9 ± 0.3	8.4 ± 0.5	7.4 ± 0.7
6RW	5.7 ± 0.3^b	4.3 ± 0.5^b	2.0 ± 0.3^b	0.4 ± 0.1^b	0.2 ± 0.1^b
6RW+ W11-a12	5.8 ± 0.4^bc	4.4 ± 0.5^bc	2.2 ± 0.3^bc	0.5 ± 0.1^bd	0.3 ± 0.1^bd

^aP < 0.05,

^bP < 0.01 vs SW (simple wound group),

^cP > 0.05,

^dP < 0.05 vs 6RW (radiation combined with wound group). The average number of peripheral white blood cells from 5 normal rats was used as 100%. Errors indicate the standard error of the mean (SEM) for n = 5 independent experiments.
