Objective To detect the antimutagenesis of carrot juice and to provide necessary data for the development of fruit-vegetable beverage. Methods Revised rat salmonella mutagenicity test was used, strains had been cultured for 48 hours at a constant temperature of 37 ℃. We counted the anaphysis strains produced in the paper circle, and judged whether there was a antimutagenesis effect according to the difference of the anaphysis strain number between the samples and the dissolvent controls. We also judged the mutagensis effect of the samples based on the anaphysis strains outside the paper circle. Results TA98-TA100 strains were all inside the normal scope, mutagenesis effect of all samples had not been observed. Conclusion Under our laboratory conditions, the inhibition rate of sample Ⅰ,Ⅳ on the induction of N-methy1-N/-nitroso-N-nitrosoguanidine(MNNG) to TA100-S9 and of sample Ⅱ, Ⅲ on the induction of aflatoxin B1( AFB1) to TA+S9 was high, and dose-response effect was obvious, also the inhibition effect of both sample Ⅰ,Ⅱ on the induction of AFB1 and that of sample Ⅰ on the Benzo(a)pyrene (BAP) to TA100+S9 was relatively high, but there was no dose-response effect exist.

A computer-based online search of Pubmed, Wanfang database and Chinese Journal Full-text Database was undertaken to identify literature and analyze characteristics of membrane oxygenator. Separation membrane, commonly used for artificial lung, has developed from drum, plate folding pattern to microporous hollow fiber membrane. In microporous hollow fiber membrane oxygenator, the hollow fiber membrane is the main place that transition occurs from oxygen to carbon dioxide. Because of the advantages in transition area and oxygenation form, it has become main study direction of artificial lung recently. Hollow fiber is mainly composed of high polymer materials with good fibrogenic capability, and membrane materials with good membrane-forming ability, heat stability, chemical stability, acid and alkali resistance, microbe erosion and antioxygenation. Current studies focus on how to improve gas exchange ability and biocompatibility, such as to improve membrane materials, optimize design and experimental and clinical evaluation of performance.
