ALPHA -TOCOPHEROL IN CANCER
Serum alpha-tocopherol of98(62 male and 36 female) cancer patients and 30 (13 male and 17 female) control healthy subjects was investigated. The cancer patients showed a significantly low level of alpha-tocopherol as compared to control healthy subjects. Also, significantly higher levels of serum alpha-tocopherol were found in complete remission patients as compared to the partial response...
متن کاملEffect of DL-alpha-tocopherol (vitamin E) on the differentiation of mouse myeloid leukemia cell.
The effect of DL-alpha-tocopherol on the differentiation of the mouse myeloid leukemia cell line (M1) was investigated using fluorometry. The reliability of the fluorometric determination was verified by the mutual overlapping of the curves of disappearance of the radioactivity recovered as alpha-tocopherol and the loss of its fluorescence. alpha-Tocopherol solubilized into the culture medium w...
متن کاملDetermination of vitamins A (retinol) and E (alpha-tocopherol) in foods by liquid chromatography: collaborative study.
A collaborative study was conducted for the determination of vitamins A and E. Existing AOAC liquid chromatographic (LC) methods are suited for specific vitamins A and E analytical applications. This method differs from existing methods in that it can be used to assay samples in all 9 sectors of the food matrix. Standards and test samples are saponified in basic ethanol-water solution, neutrali...
