Expression of survivin in human gastric carcinoma and gastric carcinoma model of rats

Table 2 Survivin expression in experimental gastric carcinoma

	Cases	Survivin expression	Positive rate (%)
Control (group B)	16	0	0
Group A
Antral mucosa of rats at week 20	10	4	40%a
Adenocarcinomas	23	18	78.3%b
Tissues adjacent to tumor	18	7	38.9%c

Ten rats of group A were killed at week 20, and the antral mucosa were examined. At week 35, all rats in both group A and B were killed and investigated. Tissues adjacent to tumor were defined as the tissues 5 mm away from the edge of tumor.

^aP < 0.05 vs control group,

^bP < 0.001 vs control group,

^cP < 0.01 vs control group.
