Figure 4: Histologic appearance of gastric mucosae of rats from all groups. (a) UCG (distilled water): Gastric ulcer, an area of discontinuity (black arrow) H and E × 40. (b) PCG (ranitidine 20mg/kg): Regular Gastric mucosa no ulcer (black arrows) H and E × 40. (c) EEG-1 (AEHSC 100mg/kg): Gastric ulcer, an area of discontinuity (black arrows) H and E × 40. (d) EEG-2 (AEHSC 200mg/kg): Gastric ulcer (black arrow) with mucus secretion (red arrow) H and E × 40. (e) EEG-3 (AEHSC 400mg/kg): Regular gastric mucosa with excessive mucus secretion (red arrows) H and E × 40. UCG = Ulcerated control group, EEG = Experimental extract group, PCG = Positive control group, AEHSC = Aqueous extract of Hibiscus sabdariffa calyx, H and E = Hematoxylin and Eosin
