The study included partially purified of polyamine oxidase (PAO) from sheep's brain tissue by dialysis and ion exchange chromatography using DEAE-cellulose techniques. Tow isoenzymes (I،II) were obtained with specific activities 3.876 and 2.856 units/ mg of protein and purification folds 11, 8 times respectively compared with crude enzyme.
The specific activity of PAO I was better than PAO II, thus we considered it for following studying. The optimal condition showed 100 μL volume of enzyme, pH=9, 40ͦ C, at incubation time 10 min. Some of properties of partially purified PAO enzyme were studied and the specificity was found to be superior to the base material, where it was given the highest activity when using spermidine. Using lineweaver_ Burk plot, the values of maximum velocity (Vmax) and Michaelis constant (Km) were found to be 0.145 Unit/ ml and 43.4 mM respectively, and potassium ion was the most activator ion to the enzyme arrived to 233.8%. The compounds (ammonium chloride, sodium fluoride, phenyl hydrazine, sodium azide and EDTA) showed a significant inhibitory effect on the activity of the enzyme (56.1%, 49.9%, 49.9%, 37.3% and 25%) respectively.

This study involves the theoretical calculation of binding energy (the free energy ΔG°) of eleven of polycyclic aromatic hydrocarbons (PAHs) compounds with catechol 1,2-dioxygenase enzyme from the gram-positive Rhodococcus opacus (3HGI) enzyme that is used for degrading these types of compounds and also identifies the values of binding energy that compactable with constant values of biological degradation rate. It is noted that binding energy inversely proportional with rate constants and binding energy (R=0.951), as the binding energy with enzyme are increased, the degradation rate are decreased.
The study observes that binding energy values were ranging between ([-5.051] - [-7.12] Kcal/mol) whereas values of root mean squared deviation (RMSD) were ranging between (1.12-1.71A°) by which accurate results have been confirmed depending on previous studies. The study also determines the amino acids that surround the compounds which are usually blinded by the hydrogen bond or hydrophobic interactions types π-π.
Finally, the study obtains a three – dimensional shape of compound's binding with enzyme of its more stable shape. Also obtains the shapes of distribution of the electronic cloud on the compound and amino acids that are surrounding them in which getting locations around the studied compound's molecule depending on their features of an amino acid (acidity – basic – hydrophobic). MOE (Molecular Operating Environment) is used for this step of calculation.

The result showed that, pecten oculi was in the three species of pleated type and consisted of 17 folds in Accipiter nisus, 26 folds in Sturnus vulgaris and 19 folds in Taeniopygia guttata, these folds were vary in their thickness, as they were thicker in Accipiter nisus than the other two species. The results also showed that the pecten oculi folds of the three species contains three types of blood vessels: large size, medium size and blood capillaries. The three types of vessels were differ in their diameter and their distribution between the folds of pecten oculi with in one speceis as well as they differ in the other three species. Pecten oculi also contains pigment cells as well as peripheral cells, it ends in the three birds speceis with a structure known as the bridge which is consist of connective tissue and dense pigment cells. The bridge is rich in blood vessels of different sizes. The present study concluded that the pecten oculi differ in components and anatomical features in different speceis of birds.

The study aimed at the determination of the pathogen of bacterial canker disease on citrus trees. The study showed that Xanthomonas axonopodis pv. citri was the major cause of the disease. The isolation process were carried by isolating 50 affected isolates obtained from various citrus fruit such as orange, lemon and tarring as well as some leaves and branches. For diagnosis, Morphological and biochemical tests were conducted. The sensitivity of these isolates was tested for six types of antibiotics; Azithromycin, Cefixime, Cefotaxime, Gentamycin, Streptomycin and Tetracycline. It was seen that all isolated bacteria were sensitive to all antibiotics. Cephotaxime showed the highest bacterial inhibition value 25mm, while Azithromycin showed the lowest one 11mm. The extract of 5 plants was also tested; onion, garlic, radish, grapes, and red pepper. Most of the used extracts affected the bacteria. The water extracted of the red pepper showed the highest inhibition value (10 mm) while the extracted water of grapes showed no inhibition value.

In the present study, antimony doped tin oxide (SnO2:Sb) thin films are prepared by atmospheric pressure chemical vapor deposition (APCVD) technique by varying the doping concentration in very small range, 1- 1.4 wt.% at a constant substrate temperature of 480 oC. The effect of Sb-doping concentration on the optical behavior of SnO2 film deposited on glass substrates are analyzed and discussed. Optical measurements showed that the average optical transmittance decreased with increased Sb concentration, and each of absorbance, absorption coefficient and extinction factor were increased in same way and regularly with increasing the concentration of Sb. However the optical reflectance and the refractive index were irregularly increased in same way with increasing the concentration of Sb. A little decrease of energy gap from 3.96 to 4.015 eV with increasing Sb concentration is observed.
