Anti toxic effect of broccoli extract on stannous dichloride toxicity.

Since Technetium-99m ((99m)Tc) has favorable physical and chemical characteristics, it is widely used radioisotope in Nuclear Medicine. However, stannous dichloride (SnCl(2)) has been widely used as a reducing agent in labeling procedure of pharmaceutical with radionuclide, it has been realized that SnCl(2) have genotoxic and cytotoxic effects on biological systems. In previous studies, it has been shown that some herbal extract can reduce genotoxic and cytotoxic effects of SnCl(2). In the present study, it is aimed to evaluate the effect of the broccoli extract on the survival of E. coli ATCC 25922 strain against to toxic effects of SnCl(2). Broccoli was extracted with methanol extraction. HPLC and TLC analysis of broccoli extract were performed. Then antitoxicity and dose response assays were performed on bacterial strain. The broccoli extract had dose dependent protective effect against SnCl(2) toxic effect on E. coli. The consumption of broccoli may alter the stannous dichloride toxicity. Broccoli extract may use as a new protective strategies against the toxic effect of SnCl(2) on patients who were taken (99m)Tc radiopharmaceuticals.
