Histochemical reactions for mucopolysaccharides in the dinosaur bone. Studies on Epon- and methacrylate-embedded semithin sections as well as on isolated osteocytes and ground sections of bone.
The dinosaur bone was examined with the aim to detect in it the presence of mucopolysaccharides. The methacrylate- and Epon-embedded semithin sections of the studied bone were found to contain substances giving positive reaction on application of histochemical procedures used for identification of mucopolysaccharides (mucosubstances). These substances were also shown to be localized in the perivascular space, within the vascular canal, and around the osteocytes. The distribution of mucopolysaccharides in the dinosaur bone turned out to be comparable with their distribution in the bones of contemporary animals.
