	Body weight before operation (g)2
Day 5	192.0 ± 3.9	199.8 ± 3.8	200.6 ± 5.0	195.2 ± 5.0
Day 15	192.4 ± 4.8	198.9 ± 4.2	194.9 ± 4.7	195.9 ± 6.0

¹Data are mean ± SE (n = 10).

²Values were not significantly different (P > 0.05) among different groups in each row by Fisher’s least significant difference test.

^*Body weight was sig-nificantly different (P < 0.05) from that in the control group (189.0 ± 4.5 g, n = 10) on day 0 by Dunnett’s test. ^†P < 0.05 com-pared with day 5 within the same group by Fisher’s least sig-nificant difference test.
