The numbers of c-Fos positive cells in brain nuclei

	SON	DMV	NTS
Group III (n = 5)	102.82 ± 7.39*	22.01 ± 2.93	127.8 ± 9.74
Group II (n = 5)	188.23 ± 16.45*	53.22 ± 6.93**	169.03 ± 16.55*
Increasing rate	82.88%	141.81%	32.23%

Values are mean ± SD, the numbers of c-Fos positive neurons were counted unilaterally in each brain nucleus, a mean value of each brain nucleus was determined by samples from ten randomly selected sections cut through the specific brain nuclei

* P < 0.05, ** P < 0.01 compared with the control group
