Expression of VEGF and CD68 in the Placenta of Gestational Diabetic Mothers (Immunohistochemistry and Ultrastructural Study) International Journal of Morphology
Yavuz,D; Balsak,D; Ekinci,C; Tahaoglu,A. E; Togrul,C; Görük,N; Aktas,A; Karaman,E.
Placental angiogenesis, is essential for embryonic and fetal development. In this study, 18 gestational diabetes mellitus and 22 control pregnancies were included. Gestational diabetes mellitus (GDM) groups compared to the control group significantly higher values were detected (p<0.01). The following histological results were assessed; villous immaturity, chorangiosis, presence of, sncytial knots,mononuclear cell infiltration ischemia and fibrinoid necrosis. To evaluate and compare the placental histology of normal and GDM pregnancies. placentas of pregnant women with gestational diabetes also in terms of angiogenesis and macrophages and ultratructural revealed by examining the possible relationship between fetal complications were investigated.

The Effect of Dietary Supplements on Healing of Alloplastic Bone Grafted Defects in Rat Tibia International Journal of Morphology
Kaya,A; Aktas,A; Akdemir,M. F; Kaya,B; Deveci,E.
The aim of this investigation was to evaluate the potential effects of the systemically delivered combination of calcium, zinc and vit-d supplementation of the locally applied alloplastic bone graft. 28 male Wistar albino rats were used in this study. In each animal, bone defects (10 mm length ¥ 3 mm width ¥ 2 mm depth) were created in the tibias. The animals were divided into four groups. In Group 1 (Control Group) rats were fed with standard rat diet. In Group 2 (Calcium Group) rats received calcium carbonate (15 mg/kg body weight) suspended in saline. In Group 3 (Calcium/Zinc Group) rats received calcium carbonate (15 mg/kg body weight) and zinc sulfate (4 mg/kg body weight) suspended in saline. In Group 4 (Calcium/Vitamin D Group) rats received calcium...

Ultrastructural Effects of the Propineb on Brain of Fetuses During Rat Pregnancy International Journal of Morphology
Ekinci,C; Tahaoglu,A. E; Yavuz,D; Deveci,E; Aktas,A; Yilmaz,T; Yumusak,Ö; Yükselmis,O.
Propineb is a fungicide with a propylene-bis-dithiocarbamate structure. Pregnant Wistar rats were exposed to 400 ppm propineb concentrations in 5 ml distilled water, 5 days per week until the end of pregnancy. The rats were treated with propineb for 16 days and the brains of litter rats were sacrificed at first day of birth after which their brains were collected. Ultrastructural examination of the brains of the fetuses and propineb-treated pregnant females revealed a variety of histopathological effects. We suggest that mitochondrial damage may be an effective factor for neuron necrosis. These results supported the proposal that the exposure to fungicides such as propineb and to other naturally occurring compounds which inhibit mitochondrial function, may...
