ABSTRACT
Objective This study aimed to investigate the protective effects of ademetionine 1,4-butanedisulfonate (SMT) against radiation injuries.Methods ICR mice were randomly divided into 7 groups,including normal control,irradiation-only,SMT administration-only,low-,medium-and high-dosages (250,500,1 000 mg·kg-1) of SMT pre-irradiation and high-dose of SMT post-irradiation in experimental groups.Blood and immunological experiments,organs index experiment and 30-day''s survival experiment were carried out to observe the protective effects of SMT on peripheral blood and immune system,organ index and the whole body injuries.Results Compared with irradiation-only group (4.23±1.16) ×109·L-1,the number of nucleated cells in bone marrow was (11.20±4.63) ×109·L-1 in the high dose of SMT pre-irradiation.The difference between two groups was significant.Compared with irradiation-only group (19.25±9.36),the colony forming unit-spleen was (39.00±7.57) in the high-dose SMT pre-irradiation group,there was a significant difference between the two groups.The index of liver,spleen,kidney and pancreas were significantly higher than those of the irradiation-only group in SMT administration groups.The survival rate of mice treated with SMT was increased,especially for the high dose group (46% lifted) when compared with irradiation-only group.Conclusion SMT can protect mice from radiation injuries.
