Placental vascularization and apoptosis in Type-1 and gestational DM.

Objective: The objective of this study is to analyze the alteration in vascularization and apoptosis in the placentas of patients with Type 1 or gestational diabetes mellitus.

Methods: Placental samples drawn from normal (n = 6), GDM (n = 6), and Type 1 DM (n = 6) pregnancies were rinsed in PBS and fixed in 4% paraformaldehyde. The obtained sections were examined by both light and electron microscopy.

Surface alteration in aging of rat tubae uterinae epithelium.

Objective: Aim of the study was evaluating arrangement of apical surface differentiation in cross-sections of tuba uterinae in different age groups by scanning electron microscope.

Material And Methods: Six groups were created with 36 Wistar rat; 1(st) group: neonate (1(th) day) (n=6), 2(nd) group: young (22(nd) day) (n=6), 3(rd) group: prepubertal (4-6 week) (n=6), 4(th) group: adult (10 week) (n=6), 5(th) group: premenopausal (8 month) (n=6), 6(th) group: old (18-20 month) (n=6). Tissue samples examined with scanning electron microscope.
