In Vivo Genotoxicity Testing Of Vitamin C And Naproxen Sodium Using Plant Bioassay

Abstract

Vitamin C (ascorbic acid) is a water-soluble vitamin and essential for collagen, carnitine and neurotransmitter biosynthesis. Naproxen sodium is propionic acid derivative and anti-inflammatory non-steroid agent. The aim of the study was to assess genotoxicity of selected medicaments and their possible effects on genetic material using Allium bioassay. The treatment of onion bulbs with fresh solutions of Naproxen Sodium (Nalgesin S®) and Vitamin C was performed using selected concentrations (550, 825 µg/ml and 250, 500, 1000 µg/ml respectively) in 72 hours time period. Control group was also set up.The microscopic parameters (mitotic index and chromosomal aberrations) of Allium root tips as well as the frequency of aberrant mitotic phases were analyzed. Both medicaments (vitamin C and Naproxen Sodium) caused increased frequency of abnormal mitosis when compared to control group.
