Expression of regulating apoptosis gene and apoptosis index in primary liver cancer

Table 1 The relationship between the protein expressions of Bcl-2, Bax and apoptosis index in cancerous tissues and paracancerous tissues

	Case	Apoptosis index %
Cancerous tissues
Bcl-2 negative	17	9.12 ± 5.37
Bcl-2 positive	5	11.00 ± 5.48
Bax negative	12	5.83 ± 1.95
Bax positive	10	14.00 ± 4.59b
Paracancerous tissues
Bcl-2 negative	18	16.39 ± 5.89
Bcl-2 positive	4	12.50 ± 5.00
Bax negative	5	10.00 ± 3.54
Bax positive	17	17.35 ± 5.62b

^bP < 0.01 vs compared with Bax negative group.
