Abstract
In the current investigation an attempt is carried out to increase the B oron-10 in liver tumor. In the first phase of the experiment, an induction of cancer using the well known carcinogens was carried out. Afterthere the rats are injected by a mixture of Boron-10 carriers was carried out using Boronophenylalanine (BPA) alone and with Sodium tetraborate Na2B4O7. It is found that the concentration of boron in a tumor was increased by about 10-20% when rats are injected by a mixture of BPA and Sodium tetraborate. This increasing should enhance the performance of the Boron-Neutron Capture therapy. The optimized conditions, namely injected concentration and half life time, which achieve maximum concentration of Boron within tumor, have been determined.
