Research Abstract

We have been continuing a long-term follow-up of collagen VI related diseases as Ullrich disease and Bethlem myopathy. The main cause of difficulty in walking in Bethlem myopathy was joint contracture, and the ambulatory period was extended by the orthopedic treatment. We have been performing genetic analysis of genes of collagen VI and related proteins. We found that recombinant thrombomodulin can improve the adhesive capacity of fibroblasts and increase the expression of collagen VI in Ullrich disease.
