| Popis: | The antimutagenic potential of glutathione (GSH) on mitomycin C (MMC)-induced micronuclei was evaluated in Swiss albino mice using the in vivo bone marrow micronucleus test. Six groups of animals were maintained simultaneously. The first group received distilled water only, the second group of animals received 2 mg/kg MMC and the third group was administered 4 doses of GSH, i.e., 20, 40, 80 and 160 mg/kg. The fourth group of animals received GSH and MMC simultaneously. The fifth and sixth groups received a cumulative dose of GSH followed by MMC after 24 h. The fifth group of animals were killed 6 h after the administration of MMC, while the sixth group were killed 24 h after the administration of MMC. The results clearly show a statistically significant increase in micronuclei in MMC-treated animals and also in animals that received GSH followed by MMC. However, there was a decrease in micronuclei in animals that received GSH and MMC simultaneously. The results clearly indicate that GSH exhibits an antimutagenic property in the presence of MMC. It is also observed the treatment with GSH prior to MMC does have some protective effect. |
