Qualitative grading of mucin production after treatment.

Energy	Imm	1 d	3 d	1 wk	1 mo	3 mo
Test level	0	0	0	0	0	0
2	0	0	0	0	+	+
2/2 passes	0	0	0	0	++	++
4	0	0	0	0	++	++
5	0	0	0	0	++	++

Imm = immediately before abdominoplasty, d = day, wk = week, mo = month, 0 = no significant staining detected, + = minimally positive staining, and ++ = moderately positive, compared to nontreated site.
