The clinical use of alkylating drugs represents an important contribution toward the chemotherapeutic management of certain forms of human cancer. Several recent reports summarize the palliative responses obtained with triethylenemelamine (TEM), triethylene phosphoramide (TEPA), and Myleran (Busulfan) in patients with malignant neoplasias of lymphatic or myelogenous origin (2, 3, 11, 12). The c...

according to the importance of positron emitters in nuclear medicine, 82mrb was produced as a member of this group of radiopharmaceuticals. after being converted into an injectable form, enough information was provided for imaging with this radiopharmaceutical. 82mrb with high radioisotopic purity and half-life of 6.5 hours, in chloride form, can be considered as a suitable positron emitter for...

Background. Chronic lower-limb ischaemia has been the subject of several studies; however, most of them do not give a comparison between vascular flow at rest and vascular flow after exercise. Nuclear medicine is vested with methods and programmes allowing the solution of this matter. The aim of this study was to define, with the use of radioisotopic methods, the perfusion disturbances of lower...

introduction: leptin, secreted from adipose tissue may have some correlation with coronary artery disease according to some reports in literature. the mean concentration of plasma leptin in patients with normal and abnormal myocardial perfusion imaging (mpi) and relation of leptin levels, independently to abnormality in mpi after correction for body mass index (bmi) was evaluated. methods: as a...
