Histopathological Changes of Umbilical Cord in Diabetic Pregnancy. Histological and Morphometrical Studies of Umbilical Cord in Pregestational and Gestational Diabetes Mellitus Pregnants

      Аннотация: Total of seventy five (75) umbilical cords with placenta were collected within 37 th to 41th weeks of gestation from Aljalaa Maternity Hospital at Tripoli city.

After proper fixation with 10% buffered formalin, tissues from a particular area of umbilical cord processed for histological study by routine procedure. All the slides were examined under light microscope. Morphometrical study measured umbilical cords diameter with a vernier caliper; area, circumference and volume were measured by computerized micrometric method in millimeters respectively. The length of umbilical cords with still attached to the placentae are measured with an elastic tap measure in centimeters and weight on electronic scale in grams.
