| Notes | Lung neoplasms; Methylseleninic acid; Bioluminescence imaging Background and objective Methylseleninic acid （MSA） is an artificially developed selenium compound. It has been proven that MSA could inhibit growth and metastasis on many tumor cells. This study investigated whetherMSA has an impact on the growth and metastasis ofL9981-Luc lung cancer transplanted model in nude mice or not. Methods A transplantated tumor model was established in nude mice. Fifteen nude mice were randomly divided into three groups： thecontrol group treated with normal saline （0.2 mL/d）, the MSA group treated with MSA solution （0.2 mL）, and the cisplatin （DDP） group injected intraperitoneally with DDP （4 mg/kg/w）. Inhibition of MSA on tumor growth and tumor metastasiswas observed using the MS Imaging System 200 Series. Results A significant difference was obserced in the primary tumor bioluminescence among the three groups （P=0.002） on 21 days post-inoculation. Primary tumor bioluminescence in theDDP group （P=0.001） and in the MSA gr |
