Ta Cruz, USA) in serum buffer (0.5 BSA in TBS containing 0.05 Tween 20, pH 7.5) at a dilution of 1:2000. Then, the antigen ntibody reaction was detected by incubating the membranes with anti-rabbit IgG peroxidase conjugate (Sigma ldrich, Saint Louis, MO, USA) at a dilution of 1:3000 in serum buffer for 1 h with gentle agitation at room temperature. The protein bands were visualized by incubating the membranes for 15?0 min in freshly prepared 4-chloro 1-naphthol (4C?

After color development, the membranes were washed twice with distilled water for about 30 min to stop the reaction, air-dried, and then photographed.Statistical PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/27741243 analysisData were expressed as mean ?S.E of 6 mice. Statistical significance between 2 groups of parametric data was evaluated by one-way ANOVA method followed by Tukey’s post-test using the SPSS statistical package (SPSS 14.0 for Windows; SPSS, Inc, Chicago, IL).

Aberrant cells percentage increased up to 45 at irradiated group (Figures 1 and 2). The most common aberrations were breaks, fragments, rings and dicentrics (Table 1). Also, polyploid cells increased significantly above the control levels. Protected and treated groups with curcumin showed significant decreases, in the percentage of aberrant metaphases (24 and 32 ), compared with irradiated group (45 ) (Figure 2). In addition, curcumin treatment both 5 days pre- and 5 days post--irradiation (protracted group) produced an additional significant decrease in percentage of aberrant cells, simply 21 (Figure 2), compared with irradiated group, since the repair was more effective than other groups when curcumin used as protracted treatment.All protected, t.
