Biochemical studies on the effect of Crataegus aqueous extract on oxidative stress during ischemia/reperfusion induced myocardial injuries
...Show More Authors

Background: myocardial ischemia-reperfusion (I/R) injury may occur in a variety of clinical settings and this remains a significant problem. Oxygen free radicals, produced on reperfusion have been shown to play a major role in myocardial I/R injury. Various therapeutic effects have been described for Crataegus. Additionally, it has been presented that Crataegus has protective effect against ischemia reperfusion induced myocardial injuries to various organs. Therefore, it seems possible that the administration of Crataegus might protect the heart against the ischemia reperfusion injury.
Objectives: I detected the chemical components and trace elements of the aqueous extract of Crataegus leaves and determine whether Crataegus extract prevents or decreases ischemia-reperfusion induced myocardial injuries in rats.
Methods: The chemical composition of the aqueous extracts of the Crataegus leaves was analysed and concentration of some trace elements was estimated .Thirty-six rats were divided into three groups as control, I/R group and Crataegus treatment group. Blood samples were taken from the rats for the biochemical parameters estimating, serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) oxidative stress levels of nitric oxide (NO) and lipid peroxidation (LPO).
Results: The results showed that the extract contain: glycosides saponins, tannins ,phenolic compounds , proteins and flavonoids . The results also showed that there were high concentrations of K , Na , Ca with (171.2 , 19 , 18.3) ppm, respectively and low concentrations of Fe, Zn ,Cu, Mg with (5.1, 3.2 ,2.3 ,1.9) ppm, respectively ,very low concentrations Cr ,Cd , Pb with (0.9 ,0.7, Nil) ppm . The levels of heart enzymes and Oxidative stress in group 3 were significantly lower than those in the group 2.Our results suggest that Crataegus treatment protects the rat heart against ischemia-reperfusion induced myocardial injuries.
Conclusion: The present study confirms that the aqueous extract of Crataegus contains (glycosides, tannins, proteins, saponins, phenolic compounds and flavonoids) as well as our results suggest that Crataegus treatment protects the rat heart against ischemia-reperfusion induced myocardial injuries .

The effect of social skill education program on adolescents in Baghdad, Iraq: a preliminary report
...Show More Authors

Background: In Iraq, adolescents confront challenges, external and internal factors and their life circumstances are exacerbated by threats to their physical and mental health.

Objective: To throw a light on training for life skills which in turn leads to promotion of adolescents physical and mental health.

Methods: A total of 120 adolescents participated in the study (50 of them were trained for life skills and the others act as control group) for the period April 2010 to Sept. 2011. Their age was 19 ± 2.4 years with male to female ratio of 1.4:1. The program consisted of several subjects concern with physical and mental health. Positive outcomes were determined. Scores

Study the Effect of Cold Plasma on the Nonlinear Properties of Polymeric Membranes Rod Amine (R3Go)
...Show More Authors

The nonlinear optical properties for polymeric (PMMA) doping with dye Rhodmine (R3Go) has been studied .The samples are prepared by normal polymerization method with concentrations of 5x10-5mol/l and a thickness of 272.5µm.

                         Plasma effect was studied on samples prepared before and after exposure to the Nd: YAG laser for three times 5, 10 and 15 minutes. Z-Scan technique is used to determine the nonlinear optical properties such as; refractive index (n2) and the coefficient of nonlinear absorption (β). It was found that the nonlinear properties is change by increasi

Effect of Insecticide “Maxxthor” on Some Hematological and Oxidative Stress Parameters in Male Albino Rats
...Show More Authors

The present study was designed to investigate the effect of different concentrations of Maxxthor on some hematological and oxidative stress parameters in male albino rats.Twenty male rats with age of 6-8 weeks and weight of 200-250gm were equally divided into four groups as follow:G1 treated with normal saline as control group,while G2,G3andG4groups were treated with(0.01,0.1,1)mg\kg body weight of Maxxthor respectively for 40 days.The following hematological parameters were measured: red blood cell(RBC),hemoglobin (Hb),white blood cell(WBC), platelets(PLT),malondialdehyde(MDA),glutathione(GSH),catalase and vitamin E. The hematological parameters results revealed highly significant(p<0.01)decreasein RBC and H,while a highly significant(p<0.

The Effect of Mechanical Combined Contact Stress with Buckling Load on the Stress Distribution in the Ball and Socket Joint Mechanism
...Show More Authors

The design of components subjected to contact stress as local compressive stress is important in engineering application especially in ball and socket Joining.  Two kinds of contact stress are introduced in the ball and socket joint, the first is from normal contact while the other is from sliding contact. Although joining two long links (drive shaft in steering cars) will cause the effect of flexural and tensional buckling stress in hollow columns through the ball and socket ends on the failure condition of the joining mechanism. In this paper the consideration of the combined effect of buckling Load and contact stress on the ball and socket joints have been taken, epically on the stress distribution in the contact area. Different

Evaluation of Myocardial Function in Cases of Gestational Hypertension Using Myocardial Performance Index
...Show More Authors

Background: Gestational hypertension represents a transient period of elevated blood pressure with  special effects on the maternal left ventricle that is different from the effects observed in chronic essential   hypertension; it affects a previously normal heart and lasts for a maximum of nine months associated with   volume and pressure overload on the maternal heart. Tei index (also called myocardial performance index)   was found to be a dependent combined index evaluating the systolic and diastolic function of the left   ventricle and represents a sensitive indicator for many types of heart diseases.
Objective: to evaluate the effects of gestational hypertension on the maternal myocar

Restrained Edges Effect on the Dynamics of Thermoelastic Plates under Different End Conditions
...Show More Authors

Frequency equations for rectangular plate model with and without the thermoelastic effect for the cases are: all edges are simply supported, all edges are clamped and two opposite edges are clamped others are simply supported.   These were obtained through direct method for simply supported ends using Hamilton’s principle with minimizing Ritz method to total energy (strain and kinetic) for the rest of the boundary conditions. The effect of restraining edges on the frequency and mode shape has been considered. Distributions temperatures have been considered as a uniform temperature the effect of developed thermal stresses due to restrictions of ends conditions on vibration characteristics   of a plate with different
