Effects of gastric pacing on gastric emptying and plasma motilin

Table 1 Effects of gastric pacing on gastric emptying parameters

Groups	n	GEt1/2 (min)
		No pacing	Acute pacing	Long-term pacing
Control	4	56.15 ± 2.34	58.52 ± 4.77
Control + glucagon	4	57.73 ± 1.65	56.90 ± 2.53
Vagotomy	6	79.42 ± 1.91a	74.41 ± 6.10	64.94 ± 1.75d
Vagotomy + glucagon	6	108.24 ± 10.75b	76.93 ± 8.55c

All the data were expressed as means ± SD.

^aP < 0.001 vs control,

^bP < 0.01 vs before injection of glucagon,

^cP < 0.05 vs before acute pacing,

^dP < 0.001 vs before a long-term pacing.
