In conclusion, the tomato has the best ability to overcome free radicals due to gamma irradiation among the treatments in the experiment.

Effect of Garlic, Stinky Bean, Dogfruit, Tomato Extracts, and N-acetylcysteine on Rats after 5 Gy Irradiation
The f ormation of reactive oxygen species (ROS) and free radicals is the most important effect of radiation exposure on biological system s . Several studies have shown that several vegetables are proven to have beneficial effect s to protect the body from free radical attacks. This current study was focused on exploring the capability of extracts of garlic, stinky bean, dog fruit, and tomato, as well as N-acetylcystein (NAC), in counteracting free radicals induced by gamma irradiation with a dose of 5 Gy. Seven treatments on male rat were as follow: A (control), B (5 Gy), C (garlic + 5 Gy), D (stinky bean + 5 Gy), E (dog fruit + 5 Gy), F (tomato + 5 Gy) and G (NAC + 5 Gy). The rats were irradiated 8 days after the sup p lement had been given. Detection of malondialdehyde (MDA), glutathione (GSH), glutathione peroxidase (GPx), catalase (CAT), and 8-hydroxy-2-deoxyguanosine (8-OHdG) was done by biochemical assays, and γ-H2AX foci w ere counted by immunofluorescence assay to the lymphocytes and plasma samples.
