Studies on cartilage formation. XX. Histochemical investigation of some enzymes of glycogen metabolsim in regenerative articular surfaces.
In 28 dogs the distal articular cartilage of the femur was removed and the regenerating articular surface on the 70th postoperative day was studied histochemically for hexokinase, glucose-6-phosphatase, phosphohexose-isomerase, fructose-1, 6-diphosphatase, aldolase, glyceraldehyde-3-phosphate dehydrogenase, lactate dehydrogenase, lactate dehydrogenase isoenzymes, phosphoglucomutase, phosphorylase, glycogen synthetase, UDP--glucose dehydrogenase, and UDP-glucuronic acid-4-epimerase. The articular surface consisted of fibrous tissue and of cartilage islets. The latter contained cells differentiating into cartilage and young chondrocytes. The glycolytic enzymes reacted positively in the regenerative articular surface. Enzyme activities were higher in the cells (particularly the chondroblasts and young chondrocytes) of the cartilage islets than in the connective tissue. In the cells differentiations into cartilage, beside the LDH isoenzymes characteristic of glycolysis, a significant LDH1 and LDH2 activity was observed. At the same site the presence of fructose-1, 6-diphosphatase-activity could be assumed, but there was no glucose-6-phosphatase activity. Glycogen synthesis proceeded in the cells of the cartilage islets and UDP-glucuronic acid-4-epimerase activity was observed in the differentiated cells. UDP-glucose dehydrogenase activity was positive in every section of the articular surface.

Antigenicity of bone tissue. I. Immunological and immunohistochemical study of non-collagenous proteins of the bovine cortical bone.
From powdered bovine bone cortex an extract has been prepared with 0.15 M NaCl and its collagen-free fraction obtained on DEAE-cellulose column was used for the immunization of rabbits. The non-collagenous protein fraction (NCP) produced against immune serum two precipitation arcs both on agarose double gel-diffusion and with immune electrophoresis. After decalcination in 10% EDTA PH 7.4, direct and indirect immune histochemical examinations were performed with fresh, freshly lyophilized, as well as with bones kept for three and six months at 20 degrees C, and the antigens were localized. Prolonged storage increased the antibody-binding capacity of the bones, whereas lyophilization decreased it. Fixation in cold acetone was suited best for immunohistochemical study of the cortical bones.
