Urtica dioica L. Stinging nettle has long been known worldwide as a medicinal plant. To study the benefits of the nettle in diabetic encephalopathy, the granule cell density of the dentate gyrus of diabetic rats was studied following administration of Urtica dioica extract. A total of 24 male albino Wistar rats were allocated equally to normal, diabetic, preventive and treatment groups. Hyperglycaemia was induced by streptozotocin (80 mg/kg) in the animals of the diabetic and treatment groups. One week after injection of the streptozotocin the animals in the treatment group received a hydroalcoholic extract of Urtica dioica (100 mg/kg/day) for 4 weeks intraperitoneally. The rats of the preventive group received hydroalcoholic extract of U. dioica (100 mg/kg/day) IP for the first 5 days and an injection of streptozotocin (80 mg/kg) on the 6th day. After 5 weeks of study all the rats were sacrificed and coronal sections were taken from the dorsal hippocampal formation of the right cerebral hemispheres and stained with cresyl violet. The area densities of the granule cells were measured and compared in the four groups. The density was lower in the diabetic rats compared with the controls (p > 0.05). The preventive group showed lower cell density than the controls (p > 0.05). The densities in the treated rats were higher than in the diabetic rats (p > 0.05). Furthermore, the control and treated rats showed similar densities (p > 0.05). It seems that U. dioica extract can help compensate for granule cell loss in the diabetic rat dentate gyrus, which can ameliorate cognitive impairment in diabetes. However, preventive use of the extract showed no significant benefit.

Urtica dioica L. (Stinging nettle) has already been known for a long time as a medicinal plant in the world. This histopathological and morphometrical study was conducted to determine the effects of the hydroalcoholic extract of Urtica dioica leaves on testis of streptozotocin-induced diabetic rats. Eighteen male Wistar rats were allocated to equally normal, diabetic and treatment groups. Hyperglycemia was induced by Streptozotocin (80 mg kg(-1)) in animals of diabetic and treatment groups. One week after STZ injection (80 mg kg(-1)), the rats of treatment group received the extract of U. dioica (100 mg/kg/day) IP for 28 days. After 5 weeks of study, all the rats were sacrificed and testes were removed and fixed in bouin and after tissue processing stained with H and E technique. Tubular cell disintegration, sertoli and spermatogonia cell vacuolization and decrease in sperm concentration in seminiferous tubules were seen in diabetic and treatment groups group in comparison with control. External Seminiferous Tubular Diameter (STD) and Seminiferous Epithelial Height (SEH) significantly reduced (p < 0.05) in the diabetic rats compared with controls and these parameters in the treatment group were similar to diabetics animals. This study showed that hydroalcoholic extract of Urtica dioica leaves, after induction of diabetes; has no treatment effect on seminiferous tubules alterations in streptozotocin-induced diabetic rats.

Stinging nettle (Urtica dioica L.) belongs to the family Urticaceae. It grows in the wild form in Asia, Europe, North America and North Africa. Stinging nettle is also a widespread ruderal plant found in Poland. Urtica dioica L., as a plant rich in biologically active compounds, is considered one of the most important plants used in phytotherapy. In vitro and in vivo studies have demonstrated its antioxidant, antiplatelet, hypoglycaemic and hypocholesterolemic properties. Research conducted in recent years indicates the possibility of using nettle in chemoprevention, diabetes, benign prostatic hyperplasia and urologic diseases.
