What is Allium cepa bioassay?
What is Allium cepa bioassay?
Allium cepa bioassay had been used from decades for the assessment of toxicants and their harmful effects on environment as well as human health. Magnesium oxide (MgO) particles are being utilized in different fields.
Which roots samples and stain is used for genotoxicity experiment?
In this study, the genotoxic effects of H 2 O 2 (Hydrogen Peroxide) and CH 2 O (Formalin) were determined using Allium cepa root tip cells while the water samples collected from the mining areas of Sorex Barobo, Surigao del Sur and Rosario, Agusan del Sur were also tested for genotoxicity.
Why is Allium cepa used in studying mitosis?
The size of chromosomes makes Allium cepa tips as favourable material for the study of the effects of chemicals on frequency of CAs which are biomarkers of damage of genetic material. The root tip cells have a very low spontaneous aberration frequency and a stable chromosome number.
What is onion root tip assay?
Allium cepa (onion) assay is a sensitive test that has been used for the determination of anti-mitotic, cytotoxic, and, or genotoxic effects of various chemical substances and herbal preparations (Grant, 1982, Smaka-kinel et al., 1996, Akinboro and Bakare, 2007, Oloyede et al., 2009, Olorunfemi et al., 2011).
What is the Allium test?
The Allium test provides a rapid screening procedure for chemicals, pollutants, contaminants, and so on that may represent environmental hazards. Root growth inhibition and adverse effects on chromosomes provide an indication of likely toxicity.
What is the use of Allium Cepa?
It is used for treatment of gastro intestinal disorders, asthma and bronchitis. The recommended mean oral dose is 50 g of fresh onion or 20 g of dried onion per day. The fresh bulbs or an extract thereof are also used topically for treatment of insect stings and warts.

What is genotoxicity test?
Genotoxicity tests are designed to detect drugs which can induce genetic damage directly or indirectly by various mechanisms of action. Compounds identified as genotoxic in these tests have the potential to be human carcinogens and/or mutagens, and ultimately may induce cancer and/or heritable defects.
