The structures of the newly synthesized compounds were elucidated through microanalysis, IR, 1H NMR, 13C NMR, and mass spectroscopy. These compounds have been subjected to in vitro antitumor evaluation by bleomycin-dependant DNA damage assay. The most active antitumor compound 6 was selected for further in vivo evaluation of antineoplastic activity against Ehrlich ascites carcinoma in mice. It was observed that our target compound has a potent antitumor activity.

Since the introduction of multislice CT scanners, CT angiography (CTA) has become a powerful tool for imaging the vascular system. The goal of this study is to compare CATHETER based angiography and CTA in the evaluation of cerebral arterial aneurysm and arteriovenous malformation AVM. A retrospective analysis of 50 patients for exploring the record of patient who underwent both multislice CT angiography (MSCTA) and CATHETER based angiography before treatment is presented during last one year in the department of Radiology, King Fahd Hospital-Jeddah, Kingdom of Saudi Arabia. The sensitivity of CTA for picking up aneurysm is 86% and the sensitivity of catheter based angiography for picking up aneurysm is 97%. The specificity of CTA for picking up aneurysm is (76%), the false positive cases are (3%) and the false negative cases are 10%. T...
