  • Title: Chromosomal and nuclear alterations in root tip cells of allium cepa L. Induced by alprazolam.
    Author: Nefic H, Musanovic J, Metovic A, Kurteshi K.
    Journal: Med Arch; 2013 Dec; 67(6):388-92. PubMed ID: 25568504.
    Abstract:
    INTRODUCTION: Alprazolam is a triazolobenzodiazepine used in panic disorders and other anxiety states. Target organ of Alprazolam is CNS, causing depression of respiration and consciousness. AIM: This study aimed to estimate the genotoxic potential of Alprazolam using Allium cepa test. METHODS: Allium cepa is one of the most suitable plants for detecting different types of xenobiotics. The test enables the assessment of different genetic endpoints making possible damage to the DNA of humans to be predicted. RESULTS: Alprazolam induced chromosomal (anaphase bridges, breaks, lagging and stickiness, abnormal spiralisation, multipolarity and polyploidy) and cytological aberrations, especially nuclear alterations (nuclear buds, fragmented nucleus and apoptotic bodies, cells without nucleus, binucleated and micronucleated cells), morphological alterations in shape and size of cells, spindle disturbance and polar deviation in root tip meristem cells of Allium cepa at all tested concentrations. Alprazolam also caused significant inhibition of mitotic index in these cells. CONCLUSION: These changes in cells are indicators of genotoxic potential of Alprazolam suggesting a need for further in vitro studies on animal and human lymphocytes as well as in vivo studies.
