Photomicrograph of pancreas stained with (H and E, ×40). (a) Normal rat receiving distilled water. (b) Normal rat receiving ethanolic extract of H. sabdariffa 1.0 g/kg. (c) Diabetic rat receiving distilled water. (d) Diabetic rat receiving HS-EE 1.0 g/kg. The islets of Langerhans of streptozotocin-induced diabetic rat were irregular in shape and size, and were mostly smaller than that of normal rats. The islets of Langerhans of diabetic rats receiving HS-EE 1.0 g/kg appeared to be larger than that of diabetic rats receiving distilled water
