摘要 目的比较翼状胬肉和正常结膜组织中基质金属蛋白酶-2(MMP-2)和基质金属蛋白酶-9(MMP-9)的表达,以探讨MMP-2和MMP-9在翼状胬肉发病机制中的作用。方法利用RT-PCR检测和酶谱分析20例翼状胬肉(A组)和20例正常结膜组织(B组)中MMP-2和MMP-9的表达。结果翼状胬肉组织中MMP-2和MMP-9的平均mRNA量为(8.38±1.38)和(5.14±1.89)灰度面积·光密度值,高于正常结膜组织中MMP-2和MMP-9的平均mRNA量(6.12±1.09)和(3.09±1.01)灰度面积·光密度值(P<0.01);翼状胬肉组织中MMP-2和MMP-9的平均酶量为(18.38±2.11)和(15.14±2.89)灰度面积·光密度值,高于正常结膜组织的MMP-2和MMP-9平均酶量(12.12±1.34)和(6.09±1.25)灰度面积·光密度值(P<0.01)。结论 MMP-2和MMP-9在翼状胬肉和正常结膜组织中表达强度不同,其可能在翼状胬肉的进展过程中发挥作用。 Objective To compare the expression of matrix metalloproteinase-2 and-9( MMP-2 and-9) between pterygium and normal conjunctiva specimens and to clarify the role of MMP-2 and-9 in pterygium development. Methods Specimens from 20 cases of pterygium and 20 cases of normal conjunctival were analysed for molecular corresponding to MMP-2 and MMP-9by using reverse transcription-polymerase chain reaction and zymography. Results The mRNA amounts of MMP-2 and MMP-9 were( 8. 38 ± 1. 38) and( 5. 14 ± 1. 89) in the pterygium respectively,which were significantly higher than the average amounts of( 6. 12 ± 1. 09) and( 3. 09 ± 1. 01) in the normal conjunctiva tissues,P 0. 01; The active levels of MMP-2 and MMP-9 were( 18. 38 ± 2. 11) and( 15. 14 ± 2. 89) in the pterygium group,which were significantly higher than( 12. 12 ± 1. 34) and( 6. 09 ± 1. 25) in the normal conjunctiva tissues( P 0. 01). Conclusion MMP-2 and-9 may related to pterygium development.
