Abstract:
Objective To observe the effect of recombinant human granulocyte/macrophage colonystimulating factor (rhGM-CSF) combined with nano-silver as a treatment on deep burn degreen Ⅱ about inflammation .Methods The burn model was built with Wistar rats .They were randomly divided into four groups ,petrolatum treatment (group A ,n= 30) ,nano-silver treatment (group B ,n=30) ,rhGM-CSF treatment(group C ,n=30) ,and rhGM-CSF combined with nano-silver treatment(group D ,n=30) . observation the inflammatory reaction ,and culture bacteria on wound of the four groups at 1st ,4th ,7th ,10th ,14th ,21th day after treatment were made .The level of IL-2 and IL-8 were measured in serums with ELISA .Results The inflammatory reaction:group A>group B>group C>group D ;Bacterias were observed in group A ,group B/C and group D at 4th ,10th ,14th day respectively af-ter treatment .The number of bacterial growed in group D was less than in group A ,group B and group C .The numbers of bacterial growed in group B and group C were less than in group A .And after 10 ,14 ,21 days treatment ,there was significantly statistical difference(P<0 .05) .There was difference among groups in the levele of IL-2 and IL-8 ,which were the lowest in group D and the highest in group A .The level of IL-2 has no significantly statistical difference between every groupat 1st day and between B and C group at 4th day(P>0 .05) .After other days treatment ,there was significantly statistical difference(P<0 .05) .There was signifi-cantly statistical difference in every group at each day of the IL-8 levele except A and B group ,B and C group ,C and D group at 1st day (P<0 .05) .Conclusion rhGM-CSF combined with nano-silver treatment could alleviate inflammatory reaction ,and be better than rhGM-CSF or nano-silver alone .
