Clin Exp Pediatr. 2009;52(6):696-700.   Published online June 15, 2009
Purpose : We screened more than 350 compounds with an endoperoxide ring structure in search of an anti-leukemic drug and found that compound 127 (c-127) could induce significant cytotoxicity in HL-60 cells. In this study, we investigated the molecular mechanisms of compound 127-induced antitumor activity on HL-60 cells. Methods : HL-60 cells were cultured in Rosewell Park Memorial Institute 1640...

Diamino-diphenyl-sulfone (Dapsone) is widely used in the treatment of leprosy and a variety of blistering skin diseases. It sometimes has adverse side effects with common usual doses, such as skin, nervous system, gastrointestinal tract, liver, kidney and hematologic toxicity. One of these side effects is a rare but serious hypersensitivity reaction called dapsone syndrome, which occurs several weeks after the...

The study on cytotoxicity of cytokines produced by the activated human NKT cells on neuroblastoma
Jin Young Cho, Young Wook Yoon, Hyang Suk Yoon, Jong Duk Kim, Du Young Choi
Clin Exp Pediatr. 2006;49(4):439-445.   Published online April 15, 2006
Purpose : α-Galactosylceramide (α-GalCer)-stimulated human Vα24 natural killer T (NKT) cells exert antitumor activity against some leukemia in a CD1d dependent and TCR-mediated manner, but could not kill CD1d - negative neuroblastoma (NB) cells. There are few reports about the direct antitumor effect of highly secreted cytokines by these cells on activation. In this study, using a cell-free supernatant (SPN)...
