Abstract

In this work were used twenty-five non-pregnant adult female mice of 4 months old Swiss albino mice) weighing 30±2 gm), twenty-five non-pregnant adult female rats of one year old Sprague-Dawley (weighing 300 ± 11 gm) and fifteen non-pregnant adult female rabbits of 2 years old White New-Zealand (weighing 3 ± 0.190 kg). After taking the uterine specimens were fixed, processed and paraffin sections were prepared and stained with different stains, and the result revealed that:Lining epithelium is tall simple columnar in mice, cuboidal to columnar in rats and cuboidal with few cilia in rabbits. The basement membrane was the thickest in mice in comparison to rats and rabbits. In some specimens of non-pregnant rat endometrium, were present few polyhedral cells with acidophilic cytoplasm. Numerous number of mast cells in the uterine tissue of non-pregnant adult rabbit more than in both mice and rats, as also those were proportionally accompanying the highest uterine vascularity in rabbit in comparison to those of mice and rats. An apoptotic cells were demarcated between the epithelial cells lining the non- pregnant adult rabbit uterus, but instead were seen vacuolated cells in rat endometrial epithelium. Fewest number of uterine glands were in mouse in comparison to those of rat and rabbit. Other results were mentioned and discussed.
