Retinoic and has been used as a trial of chemotheapeutic agent in the field of cancer
therapy and resulted some success in leukemia and breast cancer. Recently, it is being
tried on the mailnant astrocytima. We evaluated the effect of all-trans and 13
cis-retinoic acid C6 cell line cultures(14 day incubation)using MTT assay and counting
of cell numbers for establishing the basis of clinical trial. The number counting showed
51.6% and 43.1% of control in the cell number at 10£­6M concentration of
all-trans and 13 cis-retinoic acid. MTT assay showed 56.4% and 46.1% of control in the
optical absorbance at 10£­6M concentration of all-trans and 13 cis-retinoic
acid. these results indicate the possibility of both drug as effective chemotherapeutic
agents for glial cell tumbors but study will be needed for clinical trial.
