Abstract:
[Objective]To investigate the expression of collagen type I and III at mRNA and protein level in the ligamentum teres of developmental dislocation of the hip(DDH) and the normal hip. [Method]There were 6 pairs joint laxity of patients of DDH group and normal control group with paired control of same sex and age.Semiquantity RT-PCR method was used to detect the COLlal and COL3al in the ligamentum teres at mRNA level. Western-Blot method was used to detect the COLlal and COL3al in the ligamentum teres at protein level. The quantitative analysis of the COLlal and COL3al were performed by professional image software and the results were analyzed with standard statistical methods.[Result]At both mRNA and protein level COLlal expression were decreased in the DDH group compared to the control group(P0.05).[Conclusion]The decreased collagen I expression at mRNA and protein level in the ligamentum teres of the children with DDH may lead to hip joint laxity.Hip joint laxity in DDH may be independent to the content of collagen III.
