This study on the plant of Ain –AL Bason Catharanthus roseous showed the ability of callus cells that is produced by In Vitro culture technique and transformed to the accumulated media (MS 40gm/L sucrose ,2gm/L IAA Indole acetic acid , 0.5gm/L Tryptophan) to produce Vinblastine and Vincristine compounds. Extraction, purification and quantitive determination of Vinblastine and Vincristine compounds using High performance liquid chromatography technique (HPLC)were carried out. The results showed that the highest concentration of Vinblastine and Vincristine compounds were ( 4.653,12.5 (ppm /0.5 dry Wight respectively from transformed callus cells from MS 40 gm /L sucrose , 2 gm / L NAA Naphthaline acetic acid .

Aspirin Ingestion

Abstract We investigated the in vivo and in vitro effects of aspirin on several clinical assays of glycosylated hemoglobin. Acetylation of hemoglobin falsely increased the glycosylated hemoglobin fraction measured by "high-performance" liquid chromatography and electrophoresis, but isoelectric focusing and colorimetric techniques differentiated between acetylated and glycosylated fractions. Aspirin ingestion may result in an apparent increase in glycosylated hemoglobin measured with common clinical assays.
