Egyptian Journal of Forensic Sciences

Table 1 Effect of postmortem duration on scoring of skin histopathological picture in rats’ incisional wound

Parameters	Groups
Parameters	Group 1 (0 postmortem hours)	Group II (24 postmortem hours)	Group III (48 postmortem hours)
Type of inflammatory cells	Dermal neutrophils and mononuclear cells (mainly macrophages)	Almost no inflammatory cells	Almost no inflammatory cells
Edema	Present with loose myxoid degeneration/mucopolysaccharide deposition	Absent (–)	Absent (–)
Fibrous tissue and collagen	Absent	Mild (+)	Marked (+++)
Hemosiderin	Absent	Absent	Moderate (++)

Absence of histological finding was shown as (–), whereas +, ++, or +++ were considered when there were mild, moderate, or marked levels, respectively, of less than 25, 50, and 75% affection of total fields examined. Data were collected from skin tissue sections from each animal, three fields/section (n = 3)
