title: Kinky hair disease. Biochemical, histochemical, and ultrastructural studies.
abstract: The biosynthetic activities of protein and collagen from the patient of kinky hair disease, were reduced to 70 and 50%, respectively, compared with control. In tissue cultures, fast-green FCF staining coarse granules were found in the cytoplasm of skin fibroblasts from the patient. Ultrastructurally, collagen fibrils by iliac cartilage biopsy were irregular in width. Ruthenium red staining granules, presumed to be proteoglycans in the cartilage matrix, were relatively small in size and few in number. Chondrocytes showed poor development of organelles and relatively small glycogen accumulation.
