A case of congenital leukemia that originally did not express any lineage-specific antigenic markers is presented. The blast cell morphologic appearance was L1 according to French-American-British (FAB) classification and showed lymphoid characteristics by cytochemical staining and transmission electron microscopy.

In this study, in order to determine a method for obtaining a good reaction, the reactive products of 3.8% Ag (NH3)2F, using formalin as a reducing agent, were studied. Saforide RC was used as the 3.8% Ag (NH3)2F solution and 10% neutral formalinsolution was used as a reducing agent. The silver mirror test and reaction products on the root canal wall were(More)
We investigated the efficacy and safety of granisetron in 40 pediatric oncology patients who received identical chemotherapy regimens for three courses. During the first course, the emetogenicity of each chemotherapy regimen was evaluated without granisetron. Next patients received one of two doses of intravenous granisetron, i.e. 20 or 40 mcg/kg during the(More)
