Rapid mitogen-activated protein kinase by basic fibroblast growth factor in rat intestine after ischemia/reperfusion injury

Table 1 Semi-quantitative results of immunohistochemical staining for phosphorylated forms of p42/p44 MAPK in different groups

Groups	Pre-injury	2 hrs post-injury	6 hrs post-injury	24 hrs post-injury	48 hrs post-injury
Group B	-	++	++	+	++
Group C	-	+	++	+	+
Group D	-	+++	+++	+	+

"-" represents no visible positive staining, "+" less than 10 stained cells and "++" 10-30 stained cells, while "+++" represents more than 30 positively stained cells within one high power field.
