The Effects of Lycopene and Insulin on Histological Changes and the Expression Level of Bcl-2 Family Genes in the Hippocampus of Streptozotocin-Induced Diabetic Rats

Figure 1

The effects of insulin and lycopene on neural cell death of hippocampus. (a) Neuronal cell death was evaluated via hematoxylin-eosin staining at 40x magnification. C: the control group; CL: the control group treated with lycopene; D: untreated diabetic group; DI: diabetic group treated with insulin; DL: diabetic group treated with honey; DIL: diabetic group treated with insulin and honey simultaneously. (b) , comparing C, DI, and DIL with D. , comparing D with DL. (c) , comparing C, DI, DL, and DIL with D. (d) , comparing C, DI, and DIL with D. , comparing D with DL. (e) , comparing C, DI, and DIL with D. , comparing D with DL. Bar graphs indicate the mean ± SEM ().
