Histopathologic changes in aborted placenta

Histopathologic changes after thermokeratoplasty for keratoconus.

Six patients had penetrating keratoplasty following thermokeratoplasty (TKP) at different time intervals. The standard temperature used was between 90 degree and 95 degree C. with constant saline irrigation. The corneal buttons were studied by light and electron microscopy. Immediate changes observed included epithelial necrosis, marked degneration of keratocytes, and endothelial edema. After 2...

Histopathologic Changes of Rat Liver Following Formaldehyde Exposure

Purpose: This study was designed to determine the histopathologic changes of rat liver while all of the experiments were exposed to formaldehyde for 18 weeks. Materials and Methods: This study was performed on 28, 6-7 week postantal allbino wistar rats. The rats were divided into 3 case groups (E1: 4h/d, 4d/w; E2: 2h/d, 4d/w; E3: 2h/d, 2d/w) and 1 control group. The liver specimens were sectio...

Placenta changes in pregnancy with gestational diabetes.

Placental damage may be responsible for the fetal complications in pregnancies complicated by diabetes. We have analyzed the prevalence of gestational diabetes (GD) in a population of 109 pregnant women, the risk factors and the placental changes associated with gestational diabetes. Tests carried out were oral glucose tolerance test at 24-28 weeks of gestation, using the IADPSG (International ...

Anatomical and Histopathologic Analysis of Placenta in Dilation and Evacuation Specimens

Background: Anatomical and histopathologic examination of placenta in cases of abortion is crucial as to clarify the underlying causes of many adverse pregnancy outcomes. Dilation and evacuation (D&E) is the most common mode of uterine evacuation that commonly examined in pathology sections. The aim of this study is to discuss the various placental pathologies, and to demonstrate the importance...
