Background : AgNOR parameters are well known to pathologists as a proliferation marker with advantage over other proliferation markers of being cheaper, simpler and able to assess
proliferation speed as well as state , AgNOR stainability was found to be well preserved in smears kept for up to 2 years , studies have shown that AgNOR values can serve as a useful
prognostic parameter and a marker for tumour progression in different carcinomas (1) This study was conducted to see the importance of AgNOR staining in the peritoneal fluid
cytopathological examination
Patient and Methods: It was a descriptive and prospective study conducted in Department of cytopathology in the medical city and Department of pathology n the medical college of
Baghdad University, from September 2003 to June 2007. AgNOR staining was performed on 50 peritoneal fluid specimens having malignant cells and 20 other peritoneal fluid specimens
as control cases
Results: AgNOR count, size and dispersion were normal in benign mesothelial cells (the proportion of cells with 1 or 2 AgNOR dots ranged from 32% to 98% with a median of 82%
and a mean of 80.7%, S.D. 15.4 the proportion of cells with clusters ranged from 0% to12% with a median of 0% and a mean of 1.3%, S.D. 2.5 ) , higher in the malignant cells(the
proportion of cells with 1 or 2 AgNOR dots ranged from 15% to 75% with a median of 30.5% and a mean of 28.9%, S.D. 21.1, the proportion of cells with clusters ranged from 23% to88%
with a median of 67.6% and a mean of 56.2%, S.D. 36.7 ). AgNOR counts in the malignant cells were significantly greater as compared with counts of normal mesothelial cells .
Conclusion: Typing of AgNOR count, size and dispersion was found to be an important marker in differentiation between normal mesothelial cells and malignant cells of metastatic
adenocarcinoma
Background: Tumor associated tissue eosinophilia (TATE) has been described in a variety of neoplasms. In regard to squamous cell carcinoma, some studies worldwide done to assess stromal eosinophilia in oral and cervical squamous cell carcinoma. The objectives of this study is to evaluate the association of stromal eosinophilic infiltration of cutaneous squamous cell carcinoma and to detect the significance of this association. Aim of the study The aim of our study is to establish the relationship between the degree of stromal eosinophilia and the level of invasion and the histological grade in cutaneous squamous cell carcinoma. Methods: In this retrospective study done at the histopathology department of al Wasity teaching hospital for orth

The transfer of group of laws in alinear accelerator cavity to computer codes written in Fortran power station language is inorder to get a numerical calculation of an electromagnetic field generated in the cavities of the linear accelerator. The program in put contains mainly the following, the geometrical cavity constant, and the triangular finite element method high – order polynomial. The out put contains vertical and horizontal components of the electrical field together with the electrical and the magnetic field intensity.
Many researchers used different methods in their investigations to enhance the heat transfer coefficient, one of these methods is using porous medium. Heat transfer process inside closed and open cavities filled with a fluid-saturated porous media has a considerable importance in different engineering applications, such as compact heat exchangers, nuclear reactors and solar collectors. So, the present paper comprises a review on natural, forced, and combined convection heat transfer inside a porous cavity with and without driven lid. Most of the researchers on this specific subject studied the effect of many parameters on the heat transfer and fluid field inside a porous cavity, like the angle of inclination, the presenc

The range of Rayleigh number was and Darcy number values were . The theoretical part involved a numerical solution while the experimental part included a set of tests carried out to study the free convection heat transfer in a porous media (glass beads) for sinusoidal heat flux boundary condition. The investigation enclosed values of Rayleigh number (5845.6, 8801, 9456, 15034, 19188 and 22148) and angles of inclinations (0, 15, 30, 45 and 60 degree). The numerical an

Show MoreThe 2D imaging survey was conducted across an unknown K- 3 cavity that is located in Haditha area-Western Iraq.2D measurements are collected along two intercrossing traverses above the cavity with 105m length of each one. Dipole-dipole array is performed with n-factor of 6 and a-spacing equals to 5m. The inverse models of 2D imaging technique showed clearly that the resistivity contrast between the anomalous part of cavity and background resistivity of rocks is about 800:100 Ωm .In addition, the invers models showed that the depth from ground surface to the upper roof of cavity approximately equals to 11m near the cavity operator. So, the K-3 cavity is well defined from 2D imaging with Dipole –dipole array in comparison with the actua

Three types of medical commercial creams Silvazine, Cinolon Tar and Hydroquinon Domina were incorporated in this study. The medical creams were taken directly and placed uniformly on the glass slide. Each type of pharmaceutical was weighed at 1 mg and dispersed on an area of 1x1 cm. This process ensures same thickness for all samples. The creams were analyzed by using double-beam UV/visible spectrophotometer Metertech SP8001. The absorption spectrum for each of samples was measured against wavelength range of 300–700 nm.
Background: - Carcinoma of the lung has became the most common type of cancer since 1985 & the most common cause of cancer death in both males & females.
Aim of study: - To assess the diagnostic accuracy of bronchial wash cytology & application of immunocytochemical methods, using two tumor markers (low molecular weight cytokeratin & epithelial membrane antigen) for more accurate & precise diagnosis of lung tumors.
Patients, materials and methods: - Fifty fifes suspected lung cancer cases according to their clinicoradiological examinations were included in this study.
Bronchial wash cytology was performed for all the 55 patients. Smears were stained by conventional cytological stain i
Background: Endometrial Cancer (EC) is the malignant tumor originating from endometrium cell (lining of the uterus). EC incidence and mortality have increased in recent years. Routinely used methods for EC diagnosis and treatment are histopathological tissue culture after surgery and postoperative radiotherapy, however there is still not enough efficient treatment for recurrence or progression of this disease. So, there is a critical need for further EC identification by new biological ways for the prognostic diagnosis of it. Objective: This study aimed to look for ways by which could help in diagnosis of EC before the hysterectomy. Materials and Methods: 55 patients with EC and 57 healthy women were involved in this study (up to 45 years)
