Background: Lymphoblastic lymphomas (LBL) are neoplasms of precursor T cells and B cells, or lymphoblasts. The term lymphoblastic lymphoma has been used to describe predominantly lymph node– based disease; however, clinical distinction between LBL and acute lymphoblastic leukemia (ALL) has been arbitrary and has varied among different studies and institutions
Objectives: To determine the frequency of LBL among all Non-Hodgkin’s lymphoma (NHL) patients in children and to study the clinical and pathological features of LBL and assess the treatment outcome.
Methods: A retrospective study included 28 children with newly diagnosed LBL (based on morphology) below the age of 14 years over 8 years period from January 1st, 2000 to December 31st, 2007 All the patients except one were treated by modified Medical Research Council UK National Randomized Trial For Children and young Adult with Acute Lymphoblastic Leukemia (MRC UKALL) regimen, one patient was misdiagnosed as B-cell NHL and treated with United Kingdom Children’s Cancer Study Group (UKCCSG) Non-Hodgkin’s Lymphoma protocol.
Results: LBL forms 28/376 (7.1%) among NHL diagnosed in Children Welfare Teaching Hospital (CWTH) in the same period. The median age was 8.95 years (range 2 to 13.25 years) with male to female ratio of 3.7:1. Lymphadenopathy was present in 22 (78 .6%) of patients. The median duration of onset of symptoms was 7.25 months (range 1 week to 18 months). In response to treatment, 20 (71.4%) patients achieved complete remission (CR), 1 (3.6%) died during induction and 7 (25%) patients were non-responder (4 died and 3 abandoned). Of the 20 patients who achieved complete remission (CR); thirteen (46.4%) remained in continuous complete remission with a median follow up of 32.3 months, 3 (10.7%) patients died while in
CR in an average of 16.6 weeks, 2 (7.1%) patients abandoned treatment and 2 (7.1%) patients relapsed.
Conclusion: The study showed a low frequency of LBL in comparison with other studies which might be due to inadequate diagnostic facilities which differentiate LBL from other types of NHL, low survival rate might be due to advanced stages at presentation in addition to abandonment of treatment in some patients
تتزايد الصعوبات التي يعاني منها الطالب بشكل خاص والتدريسي بشكل عام في المرحلة الراهنة وذلك لنقص المصادر والكوادر العلمية الرصينة التي كانت تفخر بها جامعات العراق ولا سيما جامعة بغداد اذ أن الجامعات هي اعلى قيمة في السلم التعليمي وتعد بيئة نقية أوجدها المجتمع للتربية من خلال المناهج الدراسية التي تؤدي بشكل سليم وان الجامعة بوصفها سياقاً اجتماعياً لها أهمية في التشجيع على الإبداع وتعد جيلاً من الشباب للعمل

Abstract
The hydrometallurgical method was used to platinum and palladium leaching with aqua regia solution (3HCl: HNO3). The leaching experiments were designed to obtain the optimum conditions by using Taguchi method with 16 experiments at three different factors (time, temperature and solid to liquid ratio), and each factor has four different levels. In this study, leaching the powder sample of catalytic converter that contains platinum and palladium was conducted on the basis of the formation of chloro complexes platinum and palladium (PtCl62-, PdCl42-) with different concentrations in the acidic solution. The optimum condi
