Alteration of Dentate Gyrus Astrocytes in Diabetic Rats: Protective Role of Urtica dioica International Journal of Morphology
Golalipour,Mohammad Jafar; Ghafari,Soraya; Latifimoghadam,Mohammad Hossein; Kaboli,Sakineh.
Diabetes mellitus can cause astrocytes alterations in the central nervous system. Urtica dioica (Nettle) is among several species listed for their use against diabetes in folk medicine. Therefore, this study was done to evaluate the protective effect of Urtica dioica on astrocytes density of the dentate gyrus in STZ induced diabetic rats. In this experimental study, 21 male albino Wistar rats were randomly allocated equally into normal, diabetic and protective (nettle treated diabetic) groups. Hyperglycemia was induced by streptozotocin (80 mg/kg) in the animals of diabetic and treatment groups. Before induction of diabetes in animals, animals in protective group received hydroalcoholic extract of Urtica dioica (100 mg/kg/BW /day) for five days...

Alterations of the Giant Pyramidal Neurons (Betz Cells) in Brain Cortex of Rat Offspring Born from Gestational Diabetic Dams: A Morphometric Study International Journal of Morphology
Ghafari,Soraya; Golalipour,Elnaz; Golalipour,Mohammad Jafar.
A few studies reported the adverse effects of gestational diabetes on hippocampus and spinal cord of rat offspring. Giant pyramidal neurons are giant pyramidal neurons located in fifth layers of the gray matter in the primary motor cortex. Therefore, this study was conducted to determine the effect of gestational diabetes on the giant pyramidal neurons and the thickness of internal pyramidal layer in the brain cortex of rat offspring. On day 1 of gestation, 10 Wistar rat dams were randomly allocated into two control and diabetic groups. Five animals in diabetic group received 40 mg/kg/BW of Streptozotocin (intraperitoneally) and control animals received normal saline. We randomly selected six offspring of every subject in both groups at day 28, 56 and 84....

Golalipour,Mohammad Jafar; Azarhoush,Ramin; Ghafari,Soraya; Davarian,Ali; Fazeli,Seyyed Amirhossein.
Formaldehyde is used traditionally for fixing the cadaver, and vaporized during dissection and practical studying on cadaver. This study was designed to determine the histopathologic and morphometric changes of rat kidney while all of the experiments were exposed to formaldehyde for 18 weeks. 28 male albino Wistar rats were divided into the following three experimental groups (E1: 2hrs/d, 2d/w; E2: 2hrs/d, 4d/w; E3: 4hrs/d, 4d/w) and one control group (C). when the exposure period was expired the animals were anaesthetized with chloroform. After cervical dislocation, the abdomen was dissected and the kidneys were taken. The kidney specimens were sectioned and stained with Haematoxylin and Eosin technique for histologic and morphometric study. Data were...

Golalipour,Mohammad Jafar; Roshandel,Danial; Roshandel,Gholamreza; Ghafari,Soraya; Kalavi,Mergen; Kalavi,Khodaberdi.
Lead is one of the most important environmental pollution which is toxic to many organ systems. D-penicillamine (D-P) is a chelator drug which is used for treatment of lead toxicity for several years. This study was conducted in order to evaluate the efficacy of D-P in reducing the effects of lead on hematological indices. This study was done on 36 male adult, 6-8 weeks albino Wistar rats in Gorgan University of Medical Sciences. At first male adult rats were exposed to lead acetate in their drinking water. After 8 weeks, 6 rats were selected and blood samples were prepared to assess the effects of lead toxicity. The remained lead exposed rats were divided into recovery and treatment groups where distilled water and D-P was administered for them,...

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...
