تمتلك المستخلصات النباتية أهمية خاصة تجاه صحة الإنسان والأنشطة الحيوية لمجموعة واسعة من الأمراض. هدفت الدراسة الحالية إلى التحقق من وجود مكونات فعالة في مستخلص أوراق البردقوش ، وتحديد مضادات الأكسدة ، والأنشطة المضادة للبكتيريا والفطريات ، و LD50 ونشاطها المضاد لمرض السكر. تم تحليل المكونات النشطة نوعيا من خلال طرائق اختبار محددة. وتم قياس الأنشطة المضادة للأكسدة ، LD50 ، مضادات البكتريا والفطريات بالطرائق القياسية. وحددت الفعالية المضادة للسكري عن طريق تقييم ارتفاع السكر وفرط شحميات الدم ووظائف الكبد بالطرائق الطيفية. اكدت النتائج على وجود العديد من المكونات الفعالة تتضمن مركبات الفلافونويد والقلويدات والتربينويدات والعفص والصابونين. كما أظهرت نتائج فعالية مضادات الأكسدة أن مستخلص أوراق البردقوش يمتلك نشاطًا مضادًا للأكسدة مشابهًا لحمض الأسكوربيك. وأظهرت نتائج LD50 أن الجرعة المسموح بها هي 12.5 ملغم / مل. أشارت نتائج الفعالية الحيوية إلى أن مستخلص أوراق البردقوش يمتلك فعالية مضادة لمدى واسع من البكتريا والفطريات المرضية ، ولكن لا يوجد تأثير للمستخلص على E. coli و Staphylococcus aureus حتى عند التراكيز العالية. أظهر مستخلص البردقوش فعالية عاليًة مضادًا للسكري عند المعالجته لمدة أسبوعين بـ 4 ملغم من المستخلص يوميا. مع تحسن مستوى الدهون ووظائف الكبد ومستويات هرمون التستوستيرون بعد العلاج في مجموعة مرضى السكري مقارنة مع مجموعة التحكم. يمكن الاستنتاج أن مستخلص أوراق البردقوش يحتوي على فعالية عالية مضادة للأكسدة مع فعالية حيوية عالية ضد البكتريا والفطريات المرضية ونشاط عال مضاد للسكري مع تعزيز كبير للخصوبة ومستوى عالٍ من الجرعات المسموح بها وفقًا لقيمة LD50.
Alopecia areata is a common disorder, hypothesized to be autoimmune in etiology. Cortisone taken orally may stimulate new hair growth. Prednisone (orally administered steroid (has proved effective for patients with alopecia areata, but its potential side effects include weight gain, metabolic abnormalities, acne and menstrual problems.
This clinical study was designed to assess the clinical significance of the nutrient antioxidants (vitamin A, vitamin E and vitamin C) in reducing the dose of corticosteroids (prednisolone), and as a consequence, their side effects in patient with alopecia. The results of this study reveal the potential clinical significance of the therapy for two months with these antioxidants in reducing the dose
... Show MoreSchiff bases, named after Hugo Schiff, are aldehyde- or ketone-like compounds in which the carbonyl group is replaced by imine or azomethine group. They are widely used for industrial purposes and also have a broad range of applications as antioxidants. An overview of antioxidant applications of Schiff bases and their complexes is discussed in this review. A brief history of the synthesis and reactivity of Schiff bases and their complexes is presented. Factors of antioxidants are illustrated and discussed. Copyright © 2016 John Wiley & Sons, Ltd.
An experiment was conducted at botanical garden of Department of Biology ,College of Education (Ibn-AL –Haitham ,University of Baghdad during winter season of 2010 -2011.The aim of prsent study is to investigate the effect of Garlic (Allium sativum) extract and root extract of Ginger(Ziniber officinale)in two concentration of both extracts (20% and 30%)on growth and yield of (Cicer arietinum).The result showed that both extracts increased plant hight ,Chlorophyl content ,relative growth rate (RGR).Absolute growth rate (AGR),seeds yield .seed weight average ,biological yield ,carbohydrate and protein percentages in seeds,in comparsim with control plants .

The current study was carried out to study a high injection dose of the ethanolic extract thymus vulgaris leaf (500 ug /Kg) against the immune response combination with partially purified extracted Lipopolysaccharide ( LPS) from Proteus mirablis.Study groups were included four groups; Group I :treated with normal saline. Group II : treated with LPS antigen, Group III: injected subcutaneously ((500 ug /Kg) from ethanolic extract thymus vulgaris, group IV : injected subcutaneously (500 ug /Kg) from ethanolic extract thymus vulgaris leaf and LPS antigen, the immunological assays were measured through the phagocytic activity as (non specific immunity) after day 8 by using the phagocytic activity index.After day I4 the lymphocyte proliferations
... Show MoreIn search of novel antibacterial agent, a series of new isatin derivatives (3a-d) have been synthesized by condensation isatin (2,3-indolinendione) with piperidine (hexahydropyridine), hydrazine hydrate and Boc-amino acids respectively. Compounds synthesized have been characterized by IR spectroscopy and elemental analysis. In addition, the in vitro antibacterial properties have been tested against E. coli, P. aeruginosa, and Bacillus cereus, S. aureus by employing the well diffusion technique. A majority of the synthesized compounds were showing good antibacterial activity and from comparisons of the compounds, compound 3d has been determined to be the most active compound.
In this paper, we consider the problem of stochastic project network when some or all activities are interrupted. An approach has been built to schedule the critical activities, by constructing some expressions based on the project lateness costs due to the interruption activities. Two simple example are presented to validate our approach.
Key words: Project Management, Project scheduling, Stochastic activity duration, Stochastic PERT.
