Abstract

In histopathological evaluation, tissue samples are fixed, processed, embedded, and sectioned before being stained. Fixation is the foundation step behind the study of histology and pathology. Routine testicular tissue fixation in 10% formalin solution leads to sever shrinkage which obscures most of the morphological details. The aim of this study was to evaluate the morphological and structural alteration as well as the quantitative variations in size of the seminiferous tubule of mice testes that occur after fixation in either 10% formalin solution or bouin’s solution. The quantitative variations in size of the seminiferous tubule of the testes were performed using Motic image plus version 2.0 ml image analysis system. The quantitative parameters included both area and diameter of equivalent circle (D-Circle). Data showed that the type of the fixative solution affected only on the morphological and structural details of the testicular tissue but there were no significant differences in the quantitative parameters. This study concluded that the testicular tissue fixation with bouin’s solution can be used for better morphological and structural details and the data can be combined with data collected from samples fixed with 10% formaline solution for the histomorphological measurements.

Abstract

The aim of this study is to investigate the effect of different doses of Duprost in the liver and blood of albino mice. The current study included twenty one albino mice, obtained and grouped into 3 groups: control (3 mice), acute group (12 mice) and chronic group (6 mice). The acute group was subdivided into 4 groups and each group of 3mice, was given a lonely oral dose of (0.25ml, 0.15ml, 0.1 ml and 0.05ml respectively) for 24 hours. Whereas the third group was subdivided into 2 groups and each set was given a daily dose of (0.15ml and 0.05 ml respectively) for 30 days. After the mentioned periods, blood samples from each animal were taken for blood analysis. Then, the mice of all groups were sacrificed and the livers were removed, processed, sectioned and stained for histological analysis. In acute group, all mice that dosed with (0.25 ml) dose, died after 15 minutes of dosing. Blood results showed significant decrease in Hb level, WBC's and platelets' count among acute subgroups in comparison with chronic subgroups which showed significant increase in WBC and platelets' count, but a significant decrease in Hb levels. The histological analysis of liver in acute subgroups showed different forms of liver inflammation among acute subgroups, in comparison with chronic subgroups which showed formation of granulomatous lesions in the liver parenchyma in high dose(0.15ml) but there were inflammatory cells' aggregation in liver parenchyma among lower doses.

Abstract

Application of pesticide on vegetables will protect them from pest injury, but in another hand will hold pesticide residues inside vegetables. These residues have harmful effect against all consumers. Detection about pesticide residues has been carried out for some Iraqi vegetables (tomato, cucumber, eggplant, and zucchini) by using Gas Chromatography/Mass Spectroscopy (GC/MS). (Quick, Easy, Cheap, Effective, Rugged, and Safe) QuEChERS method has been applied for extraction pesticide residues from targeted vegetables. The GC/MS has been carried out before the treatment of residues for distinguish the vegetables that are suffering from hyper concentration in pesticide residues more than maximum residues limits (MRLs). Three kinds of solutions were used in treatment process with different concentrations: tab water, acetic acid, and citric acid. GC/MS analysis that is carried out before treatment reviled the existence of only bi-products belong to imidacloprid and oxamyl pesticides. The active ingredients of both pesticides degraded efficiently and there is no ability to trace them back. Some of the bi-products represent additives add to improve the ability of pesticide in killing pest. GC/MS had been carried out after treatment of samples with tab water, acetic acid, and citric acid to configure if the bi-products that are belong to oxamyl and imidacloprid still exist or disappeared and to evaluate the efficiency of treatment process. The GC/MS showed that treatment with tab water is the most efficient technique for mitigation pesticide residues in vegetables, whereas, treatment with acetic acid less efficient than tab water technique, whereas, treatment with citric acid is the worst technique in mitigation of pesticide residues due to appearance of more than one bi-products compounds in the results of GC/MS after treatment with citric acid.

Abstract

Cutaneous leishmaniasis (CL) is the most form of leishmaniasis disease prevalent in Iraq. CL remains a public health problem in numerous endemic countries because of the absence of safe, effective, and high-cost drugs for treatment. Macrophages are the main inhabitant cell for Leishmania; they phagocyte and allow parasite multiplying. Phagocytosis and anti-leishmanial activity of macrophage are the main factors in the elimination of Leishmania parasites. Phagosome-resident amastigotes also evade innate host defense mechanisms. Silver nanoparticles (Ag NPs) have an important effect in stimulating the production of oxygen species. The objective of this study was to examine macrophages cytotoxicity upon exposure to L. tropica and Ag NPs. Serially diluted concentrations (8, 4, 2, 1, 0.5 and 0.25 µg/ml) of Ag NPs were used following macrophages exposure to L. tropica. MTT assay was used for verification the viability of macrophages and Leishmania (promastigote and amastigote). The viability percentage of macrophages has increased 104.53 ± 4.62% compare with the control group. The results indicated the positive effectiveness of Ag NPs on proliferation of promastigote and amastigotes forms. The IC50 (50% inhibitory concentration) of Ag NPs on promastigotes was calculated 2.988 µg/ ml, and the IC50 of Ag NPs following infection of macrophages in vitro on amastigotes was measured (2.584µg/ml). The current results concluded that )Ag NPs( had an effect on macrophages stimulation to inhibit L. tropica growth in vitro following the infection with parasite.

Abstract

Gravity and magnetic data are used to study the tectonic situation of Kut- Dewania- Fajir and surrounding areas in central Iraq. The study includes the using of window method with different spacing to separate the residual from regional anomalies of gravity and magnetic data. The Total Horizontal Derivative (THD) techniques used to identify the fault trends in the basement and sedimentary rocks depending upon gravity and magnetic data. The obtained faults trends from gravity data are (N30W), (N60W) (N80E) and (N20E) and from magnetic data are (N30W), (N70E), (N20E),(N10W),(N40E). It is believed that these faults extend from the basement to the lower layers of the sedimentary rocks except the N60W trend that observed clearly in gravity interpretation. It is believed that this trend may be related to sedimentary cover only. Most residual gravity and magnetic anomalies coincide with each other concerning location and extension, which indicate that they may be created from common sources. There is a large positive gravity anomaly located at east of Hai-Fajir cities coincide with the relatively negative residual RTP magnetic anomaly. It is believed that this anomaly may represent an uplift structure within the sedimentary cover lying over deep basement rock.

Abstract

Concentration of natural occurring radioactive material (NORM) in Markazia Degasing Station in North Rumaila oilfield (NDS) was measured in this study. Then, radiological assessment due to existing of NORM in different samples including soil, sludge, scale, oil, and water collected from different stages of oil and gas production NDS was done. Radioactivity concentration of Ra-226, Th-232 and K-40 were measured using gamma spectrometry system based on HPGe detector with efficiency of 30%. The results show that some locations within NDS are contaminated with NORM. The activity in Bq/kg of Ra-226, Th-232 and K-40 range between 15.19 in oil to 68.73 in sludge, 8.5 in oil to 23.45 in sludge and 80.23 in oil to 319.73 in saline water samples respectively. The places to be more contaminated among the other places within the processing stages of oil and gas production within NDS are dehydrator and desaltor stages. These locations have to be monitored and remediated periodically.

Abstract

Fusion can be described as the process of integrating information resulting from the collection of two or more images from different sources to form a single integrated image. This image will be more productive, informative, descriptive and qualitative as compared to original input images or individual images. Fusion technology in medical images is useful for the purpose of diagnosing disease and robot surgery for physicians. This paper describes different techniques for the fusion of medical images and their quality studies based on quantitative statistical analysis by studying the statistical characteristics of the image targets in the region of the edges and studying the differences between the classes in the image and the calculation of the statistical scale (mode) between the classes in the region of the edges before and after fusion. The results proved highly efficient in the integration of medical information and increase the sharping of contrast, force the separation and show the fine details between the classes

Abstract

Kidney tumors are of different types having different characteristics and also remain challenging in the field of biomedicine. It becomes very important to detect the tumor and classify it at the early stage so that appropriate treatment can be planned. The main objective of this research is to use the Computer-Aided Diagnosis (CAD) algorithms to help the early detection of kidney tumors. In this paper, tried to implement an automated segmentation methods of gray level CT images is used to provide information such as anatomical structure and identifying the Region of Interest (ROI) i.e. locate tumor, lesion and other in kidney. A CT image has inhomogeneity, noise which affects the continuity and accuracy of the images segmentation. In order to obtain good accuracy; the noise must be removed from the input image. Those propose method is started with pre-processing of the kidney CT image to enhance its contrast and removing the undesired noise in order to make the image suitable for further processing. In our proposed work, we have proposed a hybrid filter as a combination of adaptive median and Gaussian HP filter for noise removal and image enhancement. The segmentation process is performed by using the Fuzzy C-Means (FCM) clustering and Watershed methods to detect and segment kidney CT images for the kidney region .The resulted segmented kidney CT images, and then used to extract the tumor region from kidney image.
