Wajeeh Y. Mohammed, Ausama A. Faisal --- Abdullah

Journal of University of Anbar for Pure Science , volume:7 issue:2

Psoriasis is a chronic inflammatory skin condition which affects approximately 1-3% of the world's population (1). It appears as red plaques covered with silvery scale that flakes away from the skin.Psoriatic plaques are often found on the elbows, scalp and knees but can also affect other parts of the body such as the face, feet and mucous membranes.Psoriasis is not contagious, nor is it caused by an allergy. However, the tendency to develop the condition can be genetically transmitted. Psoriasis causes itching in 60% to 70% of cases (2). However, the exact etiology of psoriasis is unknown. Abnormalities in lipid metabolism have been proposed because the abnormalities in lipids lead to abnormalities in skin formation which is made from lipids. To evaluate the serum lipids profile in psoriatic patients of Al-Anbar governorate and to compare the results with other external studies. The study group included 60 patients with psoriasis, and 30 healthy volunteers. Blood lipid profile was determined using commercial kits from reliable French and Spain companies. All patients had psoriasis involving less than 30% of body surface. Their ages ranged from 10 to 60 years with a mean of 32 years. Family history of psoriasis was positive in a percentage of (20%) of the patients. The mean levels of serum lipids (total cholesterol, triglyceride, low density lipoprotein, and very low density lipoprotein) in patients with psoriasis were found to be significantly higher than those of healthy individuals. The mean levels of high density lipoprotein were not significant. This study strengthens the relationship between the lipids intake, formation, and metabolism with the pathogenesis of psoriasis. Therefore it is concluded that psoriatic patients should be evaluated for hyperlipidemia and obstructive vascular diseases. Administrating lipid-lowering medicines for patients particularly cases with severe disease may be beneficial prognosis.

Dhia`a K. Khudier --- Nabeil A. Fawaz

Journal of University of Anbar for Pure Science , volume:7 issue:2

The location of the phase transition in the two dimensional Ising model were determined using Monte Carlo simulation with importance sampling. The magnetization persite ,energy per site , magnetic susceptibility , specific heat of a Ferromagnetic materials were calculated as a function of temperature for spin lattice interaction in zero and nonzero magnetic field . There is thus a phase transition defined by the Curie temperature. The Monte Carlo method was used to check the results and to confirm the phase transition . The internal interaction results were found to be consistent with what was expected. As a magnetic field is applied, the spins tend to align with it for ? and its effect is not significant at a very high temperature because of the thermal agitation. For ? , the alignment of the spins is possible only if the amplitude of the field is big enough.

Journal of University of Anbar for Pure Science , volume:7 issue:2

At present the research aims to individuate right formulations suitable to realize the “cure” process through ionizing radiations to get shielding with applicative properties similar if not better than that obtained with traditional thermal processes. It is worth noting that material properties, on the same formulation, are strongly dependent also on the choice of the process parameters. Additionally a shield absorbs for radiation is a function for the material it is made of, its thickness, type the material and energy of the radiation it is exposed to. Where , as the energy of the radiation increases, the thickness of the shielding must increase or a material with a higher attenuation coefficient must be used.And the results show that the linear absorption coefficient of lead powder increase with increase thicknessof lead powder . That linear absorption coefficient as a function of different thickness from (0.0 to 2.5cm.) of lead powder and lead shots where complete its test.No significant changes in linear absorption coefficient behavior of lead powder, lead shots and thickness.Although values of linear absorption coefficient of lead shots will slightly increase as in that for value of lead powder.

BADRY AL-ANI, YASIR H. AL-JURAISY --- NAHI Y. YAS

Journal of University of Anbar for Pure Science , volume:7 issue:2

The present investigation represents a preliminary study of the effect of crude extracts (aqueous, ethanolic and hexanic) of date pits (Phoenix dactylifera L. cv. Zahdi) on two malignant cell lines (human laryngeal carcinoma-Hep2 and murine mammary adenocarcinoma-AMN3) and one normal cell line (rat embryo fibroblast-REF). The study also includes evaluation of the effect of these extracts on several cytogenetic parameters such as mitotic index (MI%), blast index (BI%) and chromosomal aberrations (CA) after in vitro culture of peripheral blood lymphocytes. This work also includes a study of the therapeutic potential of one of these extracts in the treatment of transplanted murine mammary adenocarcinoma in mice.The in vitro cell growth assay showed that there was time- and concentration-dependent cytotoxic effects of crude extracts of date pits on Hep2 and AMN3 cell lines. The highest significant effect of these extracts was achieved after 72 hrs of exposure with the highest concentration (10000 ?g/ml). Ethanolic extract of pits (EP) caused growth inhibition percentage 89.4% , 93.4% for Hep2 and AMN3 respectively. However, 72 hrs exposure to EP at concentration of 10000 ?g/ml caused slight inhibitory effect on REF cell line, reaching 17.7%.On the other hand, the crude extracts of pits caused significant reduction in the mitotic index and blast index of peripheral human lymphocytes, but without any structural or numerical chromosomal aberrations. Also these extracts neither replaced phytohemagglutinin (PHA) as mitogenic agent, nor colcemide as mitotic arresting agent at metaphase.The therapeutic doses of EP were determined according to LD50 in mice. The results indicated high effectiveness of this extract in a dose- and time-dependent manner. The highest therapeutic doses of EP (1 gm/kg B.wt.) showed the best therapeutic effect by reducing the tumor volume in mice to about 83.8%.The comparison of relative tumor volumes of different groups revealed highly significant differences among all treated groups and those of untreated (control) group
