The Saanen goat is known as the greatest milk producer among small ruminat breeds. However, its morphometric features still remain unclear. Therefore, the present work aimed to investigate the functional anatomy of the upper and lower jaws as well as the volumetric properties of the male and female Saanen goat for clinical applications. The heads of 20 adult animals (10 males and 10 females) were included. Totally, 22 morphometric parameters were measured on three dimensional computed tomographic images using RadiAnt DICOM Viewer software and some parameters were measured on hot macerated sample. The mean volume of paranasal sinuses as well as conchal sinuses were estimated using stereological method. Based on the results, the differences between males and females were not significant (p>0.05) in all desired parameters.The frontal and lacrimal sinuses were the largest and smallest paranasal sinus in both sexes. Also, the dorsal and middle conchal sinuses were the largest and smallest ones, respectively. The common nasal meatus was the smallest and ventral meatus was the largest meatus in the nasal cavity.In conclusion, these findings provide a basic data that would be useful in blocking terminal branches of the cranial nerves in this breed for surgical purpose or teeth injuries treatment.

The present work aims to investigate the morphometrical, histological, and histochemical, aspects of the esophagus and stomach in two different Egyptian birds having different food habits. The animals under investigation are Kingfisher (Halcyon smyrnensis), and Hoopoe (Upupa epops). These birds were caught from Abou-Rawash Constituency and Nile Delta in Egypt. The birds were dissected; after which the esophagus and stomach were fixed and stained for the comparative histological study. From the current results, it was revealed that, there are some morphometric differences between kingfisher and hoopoe in both esophagus and stomach. The esophagus wall in Kingfisher composed of only three layers or tunics: mucosa, muscularis and adventitia arranged from the inside to outside, referring to the absence of tunica submucosa;whereas, the esophagus of the Hoopoe consists of four distinct functional layers; mucosa, submucosa, muscularis and the outermost serosa. Stomach in the two studied birds is divided into two parts, glandular or true stomach (proventriculus) and the muscular stomach or gizzard (ventriculus). The glandular stomach showed moderate differences in length and width between kingfisher and hoopoe.The mucosa of proventriculus in the kingfisher consists of number of large compound folds which appear as finger-shaped structures with gastric pits; mucous cells are most conspicuously distinguished by their "empty" appearance. While, the mucosa of proventriculus in the hoopoe have both parietal cells and chief cells which occur in the middle portion of gastric glands. The gizzard wall has a thick keratinized layer called koilin, the secretion of the gizzard glands forms the koilin in hoopoe but in kingfisher the gizzard wall is small and very thin keratinoid lining.

Purpose: To assess the effects passive smoking and heavy metal concentrations in the blood and follicular fluid on assisted reproductive technology outcome.Methods: A prospective study was conducted between March 2017 and January 2018 in population consisted of 75 female patients undergoing an In vitro fertilization (IVF) cycle at Dr. Faris Medical center for Infertility and Human Reproduction located on Heliopolis, Cairo, Egypt; with unexplained infertility who underwent intracytoplasmic sperm injection (ICSI) using GnRH-antagonist protocol. Concentrations of three toxic metals Cadmium (Cd), Lead (Pb) and Arsenic (As) were measured both in blood sera and follicular fluid specimens. Patients were evaluated in two groups both undergoing ICSI; the first group consisted of patients who does not smoke or exposed to smoking (n=28) and the group passive smoker females (n=47). Results: These three heavy metals were significantly higher in serum and follicular fluid of passive smoking females (P<0.05). Also, higher concentrations of Cd, Pb and As were found in follicular fluid of passive smoking patients in comparison with non-smoker females. However, concentrations of Cd and Pb were not significantly different between both serum and follicular fluid. Conclusion: Passive smoking could affect levels of Cd, Pb and As in serum and follicular fluid of females undergoing Intra Cytoplasmic Sperm Injection (ICSI).
