Abstract

The aim of this work is to study thebonding mechanism and the microstructure of copper to steel welded by shielded metal arc welding (SMAW). The electrodes that used are ECuSi and ECuSn8thenthe examination of microstructure by optical microscopic, it is clearlyobserved that the copper side are completely interfering with epitaxial growth when using ECuSn8 but the side of steel reveal interaction waves at the interface with nonepitaxial growth. Some of fine cracks observed at the interface with ECuSi. The use of ECuSn8 explaininterfering fine blockes from the steel inside the fusion zone.

Abstract

Most of the drugs used in the treatment of leishmaniasis have side effects, there is a need for a safe and effective drugs, therefore, in the present study heterocyclic compound containing pyrimidine ring ( 3,4-Dihydro-4-(p-anisyl)-6-phenyl pyramidine-2-(1H)-one ) was synthesized, then tested for there antileishmanial activity against Leishmania tropica promastigotes in vitro. The effect of the compound on the growth, generation number and generation time of the parasite was determined using concentrations ranging from 1 to 10 µg/ml.The effect of the compound concentration was found to be important to the parasite growth as the more the concentration the less the growth, generation number and increased the generation time. At the log phase the IC50 and IC90 were 2.5 and 10 µg/ml respectively and caused morphological distortions.The toxicity of the synthesized compound was determined using Balb/c mice model. Dixon's up and down method ( 1980 ) was found to have an LD50 of 642.5 mg / Kg of body weight.

أغلب الأدوية المستخدمة في معالجة داء اللشمانيا لها تأثيرات جانبية لذلك بات من الضروري وجود علاج آمن وفعال ضد هذا المرض ، في البحث الحالي تم تصنيع مركب يحوي على حلقة البريميدين ( 3 ، 4– داي هايدرو–4–(بارا–انيسايل )–6– فينايل بايريميدين–2–( 1H )– واحد ) ومن ثم اختباره وملاحظة فعاليته على نمو اللشمانيا الجلدية Leishmania tropica. تضمنت الدراسة تأثير المركب على النمو وعدد الجيل وزمن الجيل فضلاً عن المظهر الخارجي وأبعاد هذه الطفيليات إذ استخدمت تراكيز تراوحت ما بين 1 – 10 مايكروغرام / مل. أظهرت النتائج بأن هناك تأثير واضح على نمو الطفيليات إذ كلما زاد التركيز قل النمو وكذلك عدد الجيل فضلاً عن زيادة زمن الجيل ، وقد أظهرت النتائج بأن التركيز الذي يقتل 50% من الطفيليات IC50 هو 2.5 مايكروغرام / مل وأن التركيز القاتل لـ 90% من الطفيليات IC90 هو 10 مايكروغرام / مل عند الطور اللوغاريتمي من النمو والذي أدى إلى حدوث تغييرات واضحة في المظهر الخارجي. كذلك اختبرت سمية المركب المصنع باستخدام الفئران من نوع Balb/c بطريقة دكسون ( 1980 ) وقد ظهر بأن التركيز الذي يقتل 50% من الفئران هو 642.5 ملي غرام / كغم من وزن الجسم.

Abstract

ABSTRACT:BACKGROUND:Growth in patients with idiopathic nephrotic syndrome (INS) is influenced by several factors, they suffer the influence of the disease itself as long as there is proteinuria, caused by the increase of the glomerular permeability and leading to hypoproteinemia. The effects of the glucocorticoid treatment, which alters growth by a direct action on the growth cartilage, or via disturbances of growth factors. In this study we assess the effect of nephrotic syndrome, it's relapse rate and it's treatment (i.e. steroid), in the statural growth of steroid sensitive nephrotic patients.METHODS:A Prospective study of 110 steroid responsive nephrotic patients collected from AL- Kadhemia Teaching Hospital, Central Child Teaching Hospital, Child Wellfaire Teaching Hospital & AL-Karama Teaching Hospital. The study started from first of June 2005 to first of June 2006. Data collected as following: age, sex, date of first diagnosis, duration of disease, number of relapses per year, measurement of the height, weight and body mass index and sign of steroid toxicity.RESULTS:Total number of our patients were 110, 74(67.3%) were males and 36(32.7%) were females, with male to female ratio of 2:1. The age of our patients range from 2-18 years with a mean of 7.9+3.8 years.Thirty-one (28.2%) of them were with height below 3rd percentile for their age, 24(77.4%) were males and 7(22.6%) were females.Twenty- five (22.7%) patients were at pubertal age. Eighteen (72%) were males and 7(28%) were females, and 17(68%) of them have height below 3rd percentile.Seventy –six (69%) patients have their onset of the disease at age between 2 and 6 years. Forty-six (41.8%) of patients have disease duration of less than 3 years, 3 (6.5%) of them were have height below 3rd percentile, 46(41.8%) with duration of 3-6years, 14(30.4%) them were have height below 3rd percentile and 18(16.4%) with duration of more than 6 years, 14(77.8%) of them have height below 3rd percentile.Fifty-five (50%) patients had frequent relapses, twenty-seven (49.1%) of them have height below 3rd percentile, compared to 4(7.3%) of those with infrequent relapse had height below 3rd percentile.Forty-seven (42.7%) patients show sign of steroid toxicity(cushigoid facial appearance with or with out hypertention,obesity,hirsutism..etc) 25(53.2%) of them have height below 3rd percentile, compared to 6(9.5%) of those who have no sign of toxicity.CONCLUSSION:Nephrotic syndrome is a potentially chronic disease with patients suffering a relapsing course and being at risk of frequent courses of prednisolone therapy with increase the risk of growth delay especially in patients reaching pubertal age and still taking steroid therapy.

Abstract

AbstractBackground: Children with cerebral palsy are frequently associated with poor growth mainly due to inadequate nutritional intake resulting from feeding difficulties. The majority of the studies on growth status of children with cerebral palsy had been performed in western countries.Objectives: To evaluate growth status of a sample of children with cerebral palsy.Methods: A descriptive cross sectional study on 92 Iraqi children with cerebral palsy (52 males and 40 females). All the care givers were interviewed and anthropometric measurements of children were performed.Results: Mean age was 2.8±1.66 years with 17.4% of children were infants, 67.4% were less than 5 years of age, and 15.2% were 5 years and more. The percentage of weight for age, height for age, and weight for height z-scores under -2SD were 32.6%, 34.78%, and 11.95% respectively, and they were all higher among children of the older age group 5 years and more. Microcephally was present in 36.95% of cases, and macrocephally in 3.26% of cases. Conclusion: The study showed that the children with cerebral palsy suffer from growth retardation.Key words: Growth status, cerebral palsy

Abstract

Abstract:Back ground: This study, we evaluate the effectiveness of using recombinant GH for ten Achondroplastic children.Patient & method: the children. (7 females, 3 males) with typical features of achondroplasia, 4-14 years age, participated in this study. Physical and anthropometric measurements were taken every 3 moths, 12 months before and 12 months during GH therapy.Results: for children less than 10 year of age, the mean growth rate is increased from 3.4±0.4cm/year in the pretreatment period to 8±1.1 cm/year during the first year of GH treatment. For children more than 10 years of age, the mean growth rate is increased from 3.2± 0.6 cm/year in the pretreatment period to 5.6± 1.3 cm/year during the first year of GH treatment.Conclusion: this study and several other studies confirmed that GH therapy is beneficial in the treatment of short stature in children with Achondroplasia (during the first year of treatment), how ever, is still premature to conclude that the GH will improve the adult height.Key words: Growth hormone & achondroplasia
