Abstract

In this study binary and ternary solutions are prepared by using the sodium acetate concentrations (0.1, 0.125, 0.2, 0.25, 0.4, 0.5, 0.8, 1 M) in water and acetone –water mixtures .The important parameters such as apparent molal volume, the partial molal volume transfer, apparent molal compressibility, free energy of activation of viscous flow and thermodynamic activation parameter (enthalpy and entropy) determined of sodium acetate in water , 20%, 40% ,60% and 80% V/V acetone –water mixtures at 298.15K, 303.15K and 308.15 K from density and viscosity measurements espectively. The limiting apparent molal volumes and experimental slopes were derived from the Masson equation, have been interpreted in terms of solute–solvent and solute–solute interactions respectively. The viscosity data were analyzed using theJones–Dole equation and the derived parameter B - coefficient has also been interpreted in terms of solute–solvent interactions in the solutions.

Abstract

Immune status was examined in 30 children with atopic dermatitis, their ages ranged between 1-10 years, were clinically diagnosed in dermatology consultation at Merjan teaching hospital and 15 apparently healthy children were included as a control in the study which lasted from September to December 2012.Immunological parameters test were done by taking venous blood from the patients and healthy children to determine the level of immunoglobulins of IgM, IgG, IgA and complement proteins C3 ,C4 level in their serum .It was shown that positive changes in an immunological assays that were significant increases in IgM, IgG ,IgA , C3 and C4 levels in serum of patients in comparison to healthy children .

تم فحص الحالة المناعية لدى 30 طفلا" مصابا" بالتهاب الجلد الاستشرائي تراوحت أعمارهم بين 1-10 سنوات والذين شخصوا سريريا"في الاستشارية الجلدية في مستشفى مرجان التعليمي و15 من أطفال الاصحاء كعينة ضابطة للدراسة التي امتدت للفترة من ايلول الى كانون الاول 2012 .اختبار المعايير المناعية قد أجريت وذلك بسحب الدم الوريدي من المرضى والأطفال الأصحاء لتحديد مستوى الكلوبيولينات المناعية IgMو IgG و IgA وبروتينات المتممة C3 و C4. وقد أظهرت الفحوصات المناعية تغيرات ايجابية إذ كانت هناك زيادة معنوية في مستوى IgM و IgGو IgA وبروتينات المتممة C3 و C4 في مصل المرضى مقارنة بالأطفال الأصحاء.
