Background: Salivary gland neoplasms constitute a group of heterogeneous lesions with complex clinicopathologic characteristics and distinct biological behavior. Numerous studies have suggested geographical variation, therefore the aims of this study were to analyze the characteristics of salivary gland neoplasms in two Iraqi centers and to analyze the postoperative complications that are encountered after surgical treatment of these tumors. Materials and Methods: A retrospective study of the patients who were treated for major and minor epithelial salivary gland tumors was conducted. The analyzed data included; demographic information (age and gender), the site of the tumor, the clinical manifestations, the histological type of the tumor, the type of the treatment and the postoperative complications. Results: Fifty seven patients were included in this study. The parotid gland was involved in most patients (n=37, 64.9%). Thirty five patients (61.4%) had benign tumors while 22 patients (38.6%) had malignant tumors. The mean age of patients with malignant tumors was 52.05 (±17.3) while of patients diagnosed with benign tumors was 41.6 (±11.4) years, the difference was statistically significant (p= 0.008). Surgical treatment consisted of superficial parotidectomy, total parotidectomy, surgical excision of the submandibular gland, surgical excision of minor salivary glands and maxillectomy. The most common complication was weakness of one or multiple branches of the facial nerve, complications were significantly associated with patients’ age, whereas gender and type of tumor whether benign or malignant did not affect the complication rate Conclusions: benign salivary gland tumors are more common than malignant tumors with no gender predilection and that patients who are diagnosed with malignant tumors are significantly older that patients with benign tumors, parotid gland is the most commonly affected gland with pleomorphic adenoma as the most frequent diagnosis. Facial nerve dysfunction was the most common complication and the complication rate was significantly associated with the age of patients.
Background and Objectives: Wound healing is a complex process with overlapping phases haemostasis, inflammation, proliferation and maturation/matrix remodeling. Each phase of wound healing requires different management strategies, and inappropriate treatment can delay wound healing. The aim of the present study was to evaluate the efficacy of topical application of calmodulin as a significant augmentation of the granulation tissue production process of wound healing and to express of genes CaMKK2, MaP2K6 and CXCR4 at site of wound defect, that have versatile effects on the body and they belong to Ca/camodulin related genes. Material and Methods: In this study thirty albino male rats, weighting (300-400) gram, aged (6-8) months, wil

The comparison of the amount of revenue collection with what is expected and the process of measuring tax performance continuously by the tax administration leads to increase the collection of tax, determine the size of deviations and stand and know the reasons and take the necessary measures to address them to get a better result in the future. According to the different tasks assigned to them, criteria and indicators for measuring the tax performance vary from one organization to another. These are indicators or criteria that measure tax revenue (i.e., amounts). One of the research's main findings was to raise the tax collection leve

Background: Wound healing is a complex dynamical interaction between various cell types, the extracellular matrix, cytokines, and growth factors. osteoponetin is a substance that acts as an anti-inflammatory. Aims of study: The study was designed to identify the role of local exogenous applications of osteopontin on wound healing (in cheek skin). Materials and methods: Thirty adult male albino rats weighting an average of (250-300gm) used in this study, incisional wounds were made in the skin of the cheek of rat and they were divided into the following groups: A-Control group: 15 rats treated with 1µ l of normal saline B-Experimental groups: 15 rats treated with topical application of 1µl osteopontin.

The mode of bonding and overall geometry of the complexes were determined through physico-chemical and spectroscopic methods. These studies revealed octahedral geometry complexes. Molecular structure for the complexes has been optimised by CS Chem 3D Ultra Molecular Modelling and Analysis Program and supported a six coordinate geometry.
