A preliminary study of neck-stomach syndrome

Table 4 Cells positive for caspase-3 and IL-1β in the spinal cord of rats with cervical spondylosis mean ± SD

Group	Caspase-3-positive cells	IL-1β-positive cells
3-mo control group	2.01 ± 1.36	1.98 ± 2.01
3-mo model group	13.23 ± 3.21	26.56 ± 2.65
5-mo control group	3.26 ± 3.02	2.31 ± 2.48
5-mo model group	26.32 ± 4.01	32.01 ± 2.98

There was no significant difference between the controls, but a significant difference between the model groups at 3 and 5 mo after the operation (P < 0.05) and also the control groups vs the model groups at 3 mo and 5 mo, respectively (P < 0.05).
