Nerium oleander known as oleander has belonged to the poisonous plants its habitat in a tropical andsubtropical region. The chemical analysis with GC-Mass of the alcoholic extract of oleander leaves revealedthat this plant has many chemical compounds more than 80 compounds and high-peaks about 29 compoundswhich are represented by alkaloids, phenol, terpenes, and fatty acid. HPLC analysis showed many essentialoils that have many biological effects.To evaluate the antibacterial activity of the alcoholic extract of N. oleander against locally isolatedPseudomonas aeroginosa the broth micro-dilution method was adapted to different concentrations werestarted from 3.9 to1000 mg/ml. The results revealed that the alcoholic extract has antibacterial activitydepending on the concentration and bacterial strain.When treating the onion root cells as a model of the study to find the cellular toxic effect the results showedthat treatment with an alcoholic extract of oleander leaves with concentrations (control, 150, 300, 600,and 1200 mg /ml) for four hrs., the mitotic index (MI) was decreased to less than 50%, when treated withhigh concentrations 600,1200 mg /ml and many cases of chromosomal aberration were shown, such as theabnormal shape of the cells with a percentage about 1 and 2.8 % at the concentrations 600 and 1200 mg /ml respectively, as well as the multinucleated cells recorded the highest percentage at the concentrations1200 mg /ml with 14.4%, and nuclear lesion (chromatin degradation) were seen in a large percentage atthe interphase were recorded 13.66, 25.42, and 32.3% at the concentrations 300,600, and1200 mg /mlrespectively.
Identify the effect of an educational design according to the repulsive (allosteric) learning model on the achievement of chemistry and lateral thinking. The sample consisted of (59) students from third-grade intermediate students. They were randomly distributed into two groups (experimental and control), and the equivalence was done in (chronological age, previous achievement in chemistry, intelligence, lateral thinking). The (30) students from experimental group were taught according to the instructional design, other 29 students from the (control) group were taught according to the usual method. Two tests done, one of them is an achievement test consisted of (30) items of the type of multiple choice, the other was a lateral think
