The Effect of Orthodontic Force on Salivary Levels of Alkaline Phosphatase Enzyme
...Show More Authors

Background: Orthodontic tooth movement is characterized by tissue reactions, which consist of an inflammatoryresponse in periodontal ligament and followed by bone remodeling in the periodontium depending on the forces applied. These processes trigger the secretion of various proteins and enzymes into the saliva.The purpose of thi study was to evaluate the activity of alkaline phosphatase (ALP) in saliva during orthodontic tooth movement using different magnitude of continuous orthodontic forces.
Materials and Methods: Thirty orthodontic patients (12 males and 18 females) aged 17-23 years with class II division I malocclusion all requiring bilateral maxillary first premolar extractions were randomly divided into three groups according to the magnitude of the force application (40, 60 and 80gm). A sectional fixed appliance was bonded and designed to give labial force to the maxillary first premolar for three weeks. Unstimulated saliva was collected from the patients before force application, then 1 hour after force application, followed by 1 day, 7 days, 14 days and 21 days.Salivary levels of ALP were measured using spectrophotometer and compared with the baseline level.
Results: The results revealed that ALP enzymelevel increased with increasing magnitude of orthodontic force (from 40 to 80gm). This was statistically insignificant after 1 hour and 1 day of force application, but significant after 7, 14 and 21 days.The ALP level significantly increased from baseline after 7 days of force application and peaked at 21 day for all the three force levels.
Conclusions: The ALP level reflect the biological activity that takes place in the periodontium during orthodontic tooth movement, and therefore they can be used as a diagnostic tool for monitoring of correct orthodontic tooth movement in clinical practice.

EVALUATION THE EFFECT OF PRODIGIOSIN ON ALGD EXPRESSION IN CLINICAL ISOLATES OF PSEUDOMONAS AERUGINOSA
...Show More Authors

The aim of this study is to investigate the role of prodigiosin on P. aeruginosa' s biofilm genes involved in the pathogenicity and persistency of the bacteria; Materials and methods: Gram negative bacterial isolates were taken from burn and wounds specimen obtained from some of Baghdad hospitals. Forty six isolates were identified as Pseudomonas aeruginosa and four isolates as Serratia marcescens by using biochemical tests and VITEK 2 compact system. Susceptibility test was performed for all P. aeruginosa isolates, the results showed that 100% were resistant to Amikacin and 98% were sensitive to Meropenem. Resistant isolates were tested for biofilm formation; the strong and moderate isolates (17) were detected by PCR for AlgD gene

Effect of cobalt Ions precursor on the nanostructure of sprayed cobalt oxide thin films
...Show More Authors

In this study, Cobalt Oxide nanostructure was successfully prepared using the chemical spray pyrolysis technique. The cobalt oxide phase was analysed by X-ray Diffraction (XRD) and proved the preparation of two cobalt oxide phases which are Co3O4 and CoO phases. The surface morphology was characterized by Scanning Electron Microscope (SEM) images showing the topography of the sample with grain size smaller than 100 nm. The optical behavior of the prepared material was studied by UV-Vis spectrophotometer. The band gap varied as 1.9 eV and 2.6 eV for Co3O4 prepared from cobalt sulphate precursor, 2.03 eV and 4.04 eV for Co3O4 prepared from cobalt nitrate precursor, 2.04 eV and 4.01 eV for CoO prepared from cobalt chloride precursor where th

Effect of different concentrations of bovine serum albumin on some of the frozen sperm characteristics of the rams
...Show More Authors

This study was conducted in the Faculty of Agricultural Engineering Sciences - University of Baghdad in the field of sheep and goats in the Department of Animal Production. Effect of different concentrations of bovine albumin on some semen characteristics of frozen rams. Used in this experiment, 3 rams and their ages ranging from 2.5-3 years. The sample of the semen was diluted with Tris dilution with the addition of 10 ml of egg yolk per 100 ml, the sample by 1:1 with the tris and then the collection of sperm samples (Pooling) after the semen was divided into four treatments Control and bovine albumin at concentrations of 5, 7.5 and 10% and then complete dilution 10: 1, at 5C, dilution 20: 1, containing 5% glycerol per 100 ml. The results

Effect Of Methotrexate On Mice Embryo Liver
...Show More Authors

Methotrexate (MTX)is a multiple therapeutic drug, it's used in treatment of ectopic pregnancy, neoplastic disease, autoimmune disorders, and inflammatory conditions. It’s associated with a spectrum of side effect that includes damage to the (liver, kidney, lung and bone marrow). MTX has been associated with fetal malformations in( nervous, skeletal, gastrointestinal, and cardiac) system, and even fetal death. The study was conducted to test the effect of two doses of MTX (5and 10mg/kg) on the development of the mice liver during two gestational age (day11 and day 17) of pregnancy.18 healthy female mice were divided into three groups ,first group (control) was injected with normal saline ,second group injected with 5mg/kg and third grou

Effect of Chilling Imbibition on Seed Germination
...Show More Authors

  Tomato (Lycopersicon esculentum Mill) and cucumber (Cucumis sativus L.)  seeds were imbided with water at 10°c or 4°c for 4, 8, and 16 hours before planting to study germination rate, mean germination time, and final germination percentage as well as electrolyte leakage from chilled seeds. Seeds imbided more water at 10°c compared to that at 4°c. Coefficient velocity of germination and final percent of germination decreased with the decrease of temperature and increasing time of imbibition. Germination percent under laboratory conditions was higher than that under field conditions. Also, it was found that tomato seeds were more sensitive to chilling imbibition. Electrolyte leakage increased as temperature of imbib

Effect of Ochratoxin-A on Mouse Embryos
...Show More Authors

This study sought to determine malformation caused by Ochratoxin-A (OTA) on mouse embryos. Twenty adult female white Swiss mice (mus msculus) were divided into four groups, with five females per group, and with one male placed with two females in a cage. Avaginal plug was observed in the early morning and the day of mating was considered as day of pregnancy followed by the first day of pregnancy. Three sub lethal concentrations of OTA were applied to the respective groups (other than the control), 1mg/kg, 2mg/kg and 4mg/kg. The animals were given 0.1 ml per 10 gm body weight per concentration of OTA once a day during days 7-14 of pregnancy. The control group animals were given distilled water. The pregnant mice were dissected, and the embry

Effect of green colour on glass quality
...Show More Authors

The study of green colour in glass has a special importance on the glass quality, specially the effect of ferrous oxides content of the limestone. Results obtained that there was a reduction in green colour when different ferrous oxide contents in the limestone were added in glass production, limestone sources from two quarries, and the first contains 0.67% ferrous oxide and the second posses less ferrous oxide.

Reduction of green colour showed higher transmittance12% and it could be suggested that reduction of ferrous oxides content in the limestone is of special importance on the optical properties of glass.

Titania Effect on Sintering behavior of Alumina
...Show More Authors

The sintering behavior of Alumina was investigated by adding TiO2. The addition of TiO2 lowered the sintering temperature of the Alumina compared with those of pure Alumina. The result suggests that TiO2 acts as an activator for sintering of Alumina. Water absorption, apparent porosity and density were examined for both pure and TiO2 added to Alumina samples. The variations of sintering behavior were discussed in terms of shrinkage, porosity, water absorption and density. Thermal shock resistance was also examined. In term of this work, the way of improving the thermal shock resistance in oxide- based materials by adding reactive Titania powder to the Alumina samples. The laboratory results showed an improvement in thermal shock resistance
