The Protective Effects of Insulin and Natural Honey against Hippocampal Cell Death in Streptozotocin-Induced Diabetic Rats

Figure 1

The effects of insulin and honey on neural cell death of hippocampus. Neuronal cell death was evaluated via hematoxylin-eosin staining at 400x magnification (arrows show the dead neuronal cells). A: different parts of hippocampus; C: the control group; D: untreated diabetic group; I: diabetic rats treated with insulin; H: diabetic rats treated with honey; I + H: diabetic rats treated with insulin and honey simultaneously.
