Nashwan I. Abo

JOURNAL OF EDUCATION AND SCIENCE, Volume 23, Issue 3, Pages 1-7

Abstract
In this research Sorbitol dehydrogenase (SDH) was partially purified from sera of patients with type I diabetes mellitus by dialysis and ion exchange chromatography step by step. One peak of SDH activity was obtained with specific activity of 40.065 unit/mg protein and with purification fold of 98.9 compared to crud enzyme. Inhibition of SDH was studied by Glibenclamide and Rosiglitazone drugs, the best concentration of both inhibiters was 6mM. The mechanism of SDH inhibition by using both drugs were noncompetitive. There is no change in Km value 100 mM. Vmax value without inhibitor was 22.175 but 13.634 and 14.615 unit/ml with Glibenclamide and Rosiglitazone respectively. Accordingly, the inhibition constant Ki was calculated and appeared 7mM for both inhibitors above.
Finally, we propose that action of these drugs may contribute to decrease patients with type I diabetes complications through inhibition SDH which plays an important role in polyol pathway.

ayad Al-Obaidy; Omar Mu'ayad Al-Obaidy; Maha Akram Al-Rijabo

JOURNAL OF EDUCATION AND SCIENCE, Volume 23, Issue 3, Pages 18-27

ABSTRACT
Two Trichoderma spp. (T.harzianum and T.viride) which are well known for their use as biocontrol agents were used in this study and tested for their antagonistic activity against several plant pathogenic (and even human pathogenic) fungi, also the activity was tested against selected Gram positive and Gram negative bacteria. The proper conditions for the production of the antifungal compound were determined, and after the production and extraction of the antifungal compounds from the two Trichoderma spp., an attempt to partially characterize the nature of the antifungal compound(s) was done using several chemical analysis methods, and the results showed that the inhibition was due to the production of antifungal compounds that had many similar characteristics for both T.harzianum and T. viride but with a difference in their antifungal actions.

JOURNAL OF EDUCATION AND SCIENCE, Volume 23, Issue 3, Pages 107-128

ABSTRACT
In this work, the electrical prporties of Poly Methyl Meth Acrylates (PMMA) has been studies under the application of direct and alternating electrical field at different temperature. Morever conduction mechanism in direct field were investageted.
The current voltage characterstic for PMMA sample has been studies at different temperature. The results show that the current leakage increases as the applied voltage and temperature increase. It was also found three regions appeared in the I-V characterstic with different slops, their values approxametaly equal (1, 2 and 23) respectivly. Accordingly, one can say the conduction mechanism in this study is space charge limited current (sclc). The breakdown voltage were found for the sample at temperature 20Cº, 40Cº, 60Cº and 90Cº equal to 2000V, 1200V, 1600V and 1500V respectivly.
The study of dielectric properties of PMMA has been done by measuring the capacitance and conductance as a function of frequency. The experimetal results show that dielectrical constants( ), dielectrical loss ( ) and loss tangent (tan ) decreases as the frequency increases. While their values increases the temperature increases. The variation of loss tangent with frequency as show that the peak frequency was shifted to higher frequencies with an increase of temerature.
