Abstract: Purpose : The water ext ract of a Chinese herb , Tri pterygium hypoglaucum ( Level ) Hutch ( THH)was assayed for its effects of aneuploidy induction in mouse bone marrow cells by means of fluorescence in situ hybridization (FISH) . Methods : Kunming species mice were injected with THH into the abdominal cavity and killed at 24 h after t reatment . The bone marrow cell slides were prepared by general methods. FISH was carried out with Bio2162dU TP2labbled chromosome 8 probe. The hybridization signals were detected by combining st reptavidine-Cy3. Results : In three dose groups THH-induced chromosome 8 aneuploidy and the aneuploidy frequencies of chromosome 8 were significantly higher than the solvent cont rol ( P < 0. 001~0. 05) . Conclusion : The result indicated that THH is an aneugen of chromosome 8 in mouse somatic cells.

Key words: fluorescence in situ hybridization, Tripterygium hypoglaucum (Lvel ) Hutch, mouse bone marrow cell, aneuploidy
