turmeric extract decreased frequency of polychromatic erythrocytes micronuclei induced by iodine-131

چکیده
background: ionizing radiation irradiated from iodine-131 can induce dna damage and cell death. the cellular dna damage is the cause of mutation and cancer. the micronucleus assay in polychromatic erythrocytes was applied to assess the radio-protective effect of turmeric extract on genotoxic potential of iodine therapy. materials and methods: thirty six male albino rats were randomly divided in six groups. a single dose (200 or 500 mg/kg) of turmeric extract was injected to the rats 30 min before iodine therapy. iodine-131 (5.55 mbq) was administrated intra peritoneal to the experimental animals. the percentage of micronuclei in pce, nce and ratio of pce / (pce + nce) was determined 48 h after iodine injection for each experimental group to assess iodine-131 radiation effects with or without turmeric extract. results: iodine therapy showed a significant increase in the number of micronucleus formation. the animals treated with different doses of turmeric extract + iodine showed a significant reduction in the frequency of micronucleus compared to the animals treated with iodine-131 alone. both doses of turmeric extract had the same effect when injected 30 min prior to iodine therapy. conclusion: our results indicate protective effect of turmeric extract against genetic damages induced by iodine-131 administration.

Background: The search for potent radioprotective agents for the amelioration of radiation side effect is an important aim in radiobiology. The present study aimed to evaluate the effects of curcumin and seleno-L-methionine against radiation-induced micronucleus formation in rat bone marrow.Methods: In total, 40 male rats were divided into 8 groups (n=5 each), including control, curcumin or sel...
متن کاملGenotoxicity induced by iodine-131 in human cultured lymphocytes
131-radioiodine has been widely used as an effective radionuclide for treatment of patients with thyroid diseases. The purpose of this study was to investigate the genotoxic effects of iodine-131 in human cultured lymphocytes. Whole blood samples from human volunteers were incubated with iodine-131 (10, 50, 100 µCi/1.5ml) for 2 h. The lymphocytes were mitogenically stimulated to allow for evalu...
متن کاملDrug-induced liver injury caused by iodine-131
Iodine-131 is a radioisotope that is routinely used for the treatment of differentiated thyroid cancer after total or near-total thyroidectomy. However, there is some evidence that iodine-131 can induce liver injury . Here we report a rare case of drug-induced liver injury (DILI) caused by iodine-131 in a patient with regional lymph node metastasis after total thyroidectomy. A 47-year-old woman...
