OBJECTIVE To determine absorption coefficients for sodium chloride solution (saline) and balanced salt solution at the 193- and 213-nm laser wavelengths. METHODS Absorption coefficients were obtained for each of the component species found in balanced salt solution. This was achieved by measuring laser pulse transmission through solutions of varying concentration. The experiments were repeate...

Teniposide (VM-26) and etoposide (VP-16-213) were eval uated for their effects on methotrexate transport and metabo lism in Ehrlich ascites tumor cells in vitro. VM-26 (10 JUM)does not alter influx of methotrexate but slows efflux of the drug which leads to an increase in the steady-state level of ex changeable antifolate. VM-26 stimulation of net methotrexate transport occurs within 5 min of e...

Radioimmunotherapy (RIT) is an emerging treatment option for non-Hodgkin lymphoma (NHL) producing higher overall response and complete remission rates compared with unlabelled antibodies. However, the majority of patients treated with conventional or myeloablative doses of radiolabelled antibodies relapse. The development of RIT with alpha-emitters is attractive for a variety of cancers because...

PURPOSE To evaluate the efficacy of sodium hypochlorite (1 : 10) and iodophor disinfectants on alginate impressions along with their effect on the survived bacterium count on the gypsum cast. MATERIALS AND METHODS Four alginate impression on each dentate patients were made, of which Group I were not washed or disinfected, Group II impressions were merely washed with water, Group III were disi...
