    Objective To observe the short-term curative effect of the concentration of serum soluble interleukin-2 receptor (SIL-2R) and the clinical significance on TDG patients treated with radioiodine (131I).Methods The concentration of SIL-2R/FT3、FT4、TSH was measured with ELISA/RIA in the light of the clinical symptoms and signs.Results Insufficient dose of ATD have some effect in controlling the clinical symptoms and signs, the SIL-2R concentration is higher than that of the fellow-up and control groups;2 months after the treatment with 131I, the clinical symptoms and signs are serious and the concentration of FT3、FT4/SIL-2R is higher than that 4 months later.In the fellow-up group, the clinical symptoms and signs disappearred, the concentration of FT3、FT4、TSH/SIL-2R are normal.Conclusions The immune response are violent on these TDG patients treated with 131I after 2-4 months, the concentration of SIL-2R is higher and the clinical symptoms/signs are more serious treatment with 131I after 2-5 years, the concentration of SIL-2R is normal and the clinical symptoms/signs are disappeared.

    Objective To observe the protection of glutamine on radiation-induced intestinal mucosa injury.Methods Thirty rats were randomly divided into normal control group (group A), radiation control group (group B) and glutamine protection group (group C).The rats were received abdominal radiation of 1 000 cGy.Feeding glutamine began since the day before radiation in group C.Four days later, the rats were killed, and the intestinal bacteria translocation, the concentration of endotoxin in blood and pathological changes of intestinal mucosa were measured or observed.Results Bacteria translocation was not found in group A, but evident in group B, and much lighter in group C than in group B.The concentration of endotoxin in blood was very low in group A, very high in group B.but much lower in group C than in group B.The villus edema, mucosa infiltrated with informative cells and epithelial exuviation were found in group B, but these pathological changes were much lighter in group C, and not found in group A.Conclusion Whole abdomen radiation will evidently cause intestinal mucosa injury in rats, and bacteria translocation and endotoxinemia would occur.Glutamine can prevent those changes.

    This paper described cobalt-60 source replenishing processes in three radiation facilities in Suzhou.In all 13 replenishing practices, due to the performing of the radiation hygienic monitor and taking correct measures taken for control of personnel exposure dose, no incident including personnel over-exposure to radiation occurred.By this, the safty and health of sourcereplenishing operators got secured.
