The present study was revealed some histological observations of interstitial glands in Iraqi buffalo's ovaries. This study was conducted on (24) ovaries collected from Al-Najaf slaughter house. The ovarian tissue specimens was fixed in (10%) formalin and histological preparations were carried out, then stained with H and E. Histologically the overian buffalo cortex at six year old that revaled single glands were lined by simple cuboidal epithelial cells. The glands were surrounded by collagen fibers, blood vessels and fibroblasts. The ovarian cortex at nine years old consisted of group of interstitial glands, lined by cuboidal cells. The epithelial lining single and group of interstitial glands were filled with fat droplets. The lumen of groups of interstitial glands contains acidophilic secretion. The present study was suggested that the present of fat droplets in the cells of interstitial glands due to androgens (steroid hormones) and that ensure less fertility in the female buffaloes.

This study is conducted on back skin of three female belong to Millivora capenesis wild animals. Histological preparations carried out to reveal the structural features of the stratum of epidermis. The skin of Millivora capensis was covered with keratinized stratified squamous epithelium, the mean thickness is 427.85 ± 4.28 μm. The superficial layer is stratum corneum. The basic properties of this stratum consist of dead, flattened, polygonal cells which are free from nuclei and keratin accumulate in dead cells in order to give protective feature. The mean thickness of stratum corneum is 90.5 ± 2.44 μm. Beneath the stratum corneum, there is translucent layar composed of keratin fibrils and homogenous materials which is termed Eldin. The mean thickness of stratum lucidum is 18.14 ± 0.52 μm. While the mean thickness of stratum granulosum intensive affinity to basophilic spinosum is formed from prickle cells with cytoplasmic processes like spines which represented the desmosomes. The mean thickness of both stratum basal is 55.63 ± 1.75 μm .Our histological findings revealed epidermal papillae extended to the papillary layer of dermis, and these papillae were bifurcates and some papillae fused with each other in order to give the rigidity and power to epidermis.
