Background: Because of wide use of Functional Endoscopic Sinus Surgery (FESS) technique in the recent years and basic role of coronal computed tomography (CT) scan in demonstrating the normal drainage route of para-nasal sinuses, identifying the major patterns of inflammatory sinonasal disease and accompanied anatomical variations is essential for appropriate preoperative surgical planning. In review of publisthed literature, there is no data on CT patterns of chronic inflammatory sinonasal disease and their accompained anatomical variations of nose and PNS in our local population.Objectives: was to determine the frequency of CT patterns and variations in patients with sinonasal symptoms.Methods: This was a cross sectional descriptive study conducted on 404 consecutive patients with clinical manifestations of chronic rhinosinusitis referred to radiology department of Alkindy teaching hospital. Coronal and if needed axial CT scan were taken from them. CT scans were reviewed and inflammatory patterns and accompanied anatomical variations were specified.Results: Five major recurring patterns of inflammation including infundibular 23.76%, ostiomeatal unit (OMU) 21.78%, sphenoethmidal recess (SER) 7.92%, sinonasal polyposis 19.80% and sporadic 20.79% were seen. Special pattern was noted in 3.96% while normal CT examination was noted in 9.90%. The total percentage was more than 100% due to simultaneous occurance of more than one pattern in the same case. In 73.2% of cases accompanied anatomical variation including septal deviation (34%), concha bullosa (26%), Agger nasi cell (13%), giant bulla ethmoidalis (12%), Haller cell (8%), pneumatization of uncinate process (5%), paradoxic middle turbinate (4%), and Onodi cell (2%) were seen.Conclusion: In this study, the concept of the major inflammatory patterns of sinonasal disease was introduced and their frequncies in our local poluplation were reported. By applying these patterns to the radiological report, more tailored and safe endoscopic sinus surgery could be possible
Lead acetate as one of the environmental pollutants can threats the life of living creatures in many ways, it has a long half-life, accumulates mainly in the soft tissue and leads to adverse effects in these tissues. An experiment was conducted to study the effect of oral feeding of lead acetate on histological features of liver, kidney, testis and muscle of albino mice. Mice were treated with 0.05 mg/100 ml lead acetate (LA) for 10 days (group A) and for and for 20 days (group B) and for 30 days (group C). The histological section of liver of mice group A characterized by slightly blurred trabecular structure with foci of hepatitis which increased with cytoplasmic vacules in group B but in group C liver reveal necrosis, heamorrhage,

Abstract
The goal of current research to describe and diagnose the level of attention of doctors to design and regulatory dimensions, (strategic vision, organizational structure, organizational processes, business systems, personnel), and the performance of hospitals and dimensions, in six hospitals in medicine and selected a sample for research, as well as identify organizational design effect in the performance of hospitals and dimensions (efficiency, the development of human resources, patient satisfaction, achieve financial results, quality of health care).
Research has focused in part theoretical on key variables to look organizational des

A field experiment was conducted to grow the wheat crop during the fall season 2020 in Karbala province, north of Ain Al-Tamr District in two locations of different textures and parent materials. The first site (calcareous soil) with a sandy loam texture, is located at (44° 40′ 37′) east longitude and (32° 41′ 34′) north latitude, at an altitude of 32 m above sea level, and an area of 20 hectares. As for the second location (gypsum soil) with a loam texture, it is located at a longitude (45° 41′ 39′) east and a latitude (33° 43′ 34′ north) and at an altitude of 33 m above sea level and an area of 20 hectares. To find out the effect of different tillage systems on water productivity and wheat yield under center pivot irri
