摘要
目的观察不同温度下不同培养基对体外培养泡球蚴原头节的影响,探讨泡球蚴原头节体外培养合适条件。方法按照培养基的不同,随机分为3组:Ⅰ组为含10%胎牛血清的RPMI-1640(4℃、25℃、37℃);Ⅱ组为含10%胎牛血清的D-MEM(4℃、25℃、37℃);Ⅲ组为含10%胎牛血清的M199(4℃、25℃、37℃)。观察各组泡球蚴原头节存活、生长情况,并记录原头节存活率及最长生存时间。结果 RPMI-1640培养基、D-MEM培养基与M199培养基中泡球蚴原头节的存活率有统计学差异(P<0.05),RPMI-1640培养基与D-MEM培养基中泡球蚴原头节的存活率无统计学差异(P>0.05);4℃、25℃与37℃泡球蚴原头节的存活率无统计学差异(P>0.05),但RPMI-1640培养基在4℃及37℃,D-MEM培养基在25℃泡球蚴原头节存活率较高;各组在第3d和第9d泡球蚴原头节存活率有统计学差异(P<0.05)。4℃各组原头节存活时间明显高于25℃组和37℃组。结论不同温度及不同培养基对体外培养泡球蚴原头节的存活的影响不同,RPMI-1640在4℃下培养,D-MEM在25℃培养,原头节成活率较高,存活时间较长,M199培养基不适合泡球蚴原头节的体外培养。
In order to observe the effects of different culture media and temperature on protoscoleces of Echinococcus multi‐locularis ,they were randomly divided into RPMI‐1640 group ,D‐MEM group and M199 group ,and cultured in three degrees of temperature （4 ,25 and 37 ℃） with 10% fetal calf serum （FCS） .Protoscoleces were counted by light microscope with 0 .1%eosin staining ,and calculated survival rate （per 100 protoscoleces） everyday until all the parasites died .At the same time ,the average number of the preservation days was observed .The experiment results showed that the survival rate of protoscoleces in RPMI‐1640 and D‐MEM groups were higher than that in M199 group （P〈0 .05） and there’s no significant difference between RPMI‐1640 group and D‐MEM group （P〉0 .05） .The survival rate of protoscoleces in RPMI‐1640 group at 4 ℃ and 37 ℃and D‐MEM group at 25 ℃ were higher ,but there was no significant effect of 4 ,25 and 37 ℃ on the survival rate of proto‐scoleces （P〉0 .05） .Significant difference were found in the survival rate of protoscoleces on the 3rd day and the 9th day in these three groups （P〈0 .05） .The average number of the preservation days were 34 days in RPMI‐1640 group at 4 ℃ ,36 days in D‐MEM group at 25 ℃ and 23 days in M199 group at 4 ℃ .It was concluded that the effects of different culture media and tem‐perature on protoscoleces are different ,and the RPMI‐1640 at 4 ℃ and D‐MEM at 25 ℃ are more suitable for culturing proto‐scoleces in v itro .
