The cells were shammed or irradiated with different dosages of UVB radiation and treated with the above TCM monomers. The damage of fibroblasts was observed with inverted phase contrast microscope.Cellular proliferation activity was detected by MTT method.The secretory volume of IL-6 and TNF-α was measured by ELISE. Results The damage degree of the cells irradiated was dependent with the irradiated doses and the proliferation activity reduced by 28%-44%.

It is necessary to carry out a thorough study on pest control technology with DMDS, with an expectation of obtaining a new fumigant of methyl bromide alternative.2. Investigation of the toxicity of fumigation on adult and mixed stages of the three most tolerant insect species -- Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum -- under a range of EtF、DMS and DMDS doses in a Flow-through Fumigation System shows that the FTFS procedure offers a constant concentration of fumigant with low CO2 concentrations and ensures that the fumigant toxicity is effectively not compromised by CO2. In comparison with chamber fumigation method, the toxicity data of EtF、DMS and DMDS obtained from this experiment is more accurate by using FTFS.
