Several animal model studies have shown that Diabetes mellitus can affect on the activity of hippocampus astrocytes, but these studies reported controversial findings. This study was done to evaluate the preventive and treatment effect of Urtica dioica (U. dioica) on astrocytes density in the CA1 and CA3 subfields of hippocampus of streptozotocin (STZ) induced diabetic rats. Twenty-eight male albino Wistar rats were randomly allocated equally into control, diabetic, U. dioica treatment and U. dioica preventive groups. Hyperglycemia was induced by STZ (80 mg/kg/BW). One week after injection of the streptozotocin, animals in treatment group were received hydroalcoholic extract of U. dioica (100 mg/kg/BW /day) for 4 weeks by intraperitoneally. In preventive...

Cephalometry or measurement of human head is used in identification, forensic medicine, plastic surgery, orthodontics, archeology and examine the differences between races and ethnicities. This descriptive investigation was undertaken on 198 young Turkman males to determine the cephalic index and head phenotype among them in Gorgan, North of Iran. In this study cephalic index was determined by classic cephalometric method. Mean and standard deviation of cephalic index was 80.4 + 4. Based on the cephalic index, the head shape of 42.4% of individuals were brachycephalic, 7.6% hyperbrachycephalic, 40.9% mesocephalic and 8.1% dolicocephalic. This research showed that Turkman individuals have typical brachycephalic phenotype. In comparison to other studies, we...

Autores: Haidari,Kamran; Jahanshahi,Mehrdad; Golalipour,Mohammad Jafar.
Cranial capacity and brain weight are important measurements in the study of racial/ethnic differences. Using linear (Lee­Pearson's) formula, brain weight and cranial capacity were estimated in 398 normal 17 to 20-year-old males (200 native Fars and 198 Turkman) males in Northern Iran. The dimensions of the head measured with spreading caliper and auricular head spanner. The mean±S.D of brain weight and cranial capacity in native Fars males were 1343.45±102.37 cm3, and 1390.47±105.95 g, and that of Turkmans were 1163.02±115.76 cm3 and 1203.73±119.81 g, respectively. Cerebral Index was 3.40 ±0.37 % and 2.52 ±0.37 % in Native Fars and Turkmans, respectively and cerebral quotient was higher in Turkmans (8.34) than Native Fars males (7.95). This study showed,...

Autores: Fazeli,Seyyed Amirhossein; Gharravi,Anneh Mohammad; Jahanshahi,Mehrdad; Ghafari,Soraya; Behnampour,Naser; Golalipour,Mohammad Jafar.
The pyramidal cell density of CA1 hippocampal subfield following STZ-induced diabetes in young rats were studied. 12 male albino 6-week Wistar rats were allocated equally in groups of normal and diabetic. Hyperglycemia induced by Streptozotocin (80 mg/kg) in animals of diabetic group. After 5 weeks of study, all the rats were sacrificed and coronal sections were taken from dorsal hippocampal formation of the right cerebral hemispheres and stained with crysel violet. The area densities of the CA1 pyramidal cells were measured and compared among two groups. No significant difference between the densities of two experimental groups was found. The results can arise from the short period of diabetes and also the possible regenerative processes in developing...
