title: [Canine panosteitis--an idiopathic bone disease investigated in the light of a new hypothesis concerning pathogenesis. Part two: Biochemical aspects and investigations].
abstract: The pilot study included serum analysis of ionized calcium, copper, zinc, various hormones and amino acid profiles from dogs affected with panosteitis, as well as protein electrophoresis performed on bone biopsies. Results of these analyses are as follows: ionized calcium, copper, zinc and hormones (parathyroid hormone, IGF-1, T3 and T4) were within reference ranges. Eleven of 23 serum amino acids from panosteitis-affected dogs were found to be significantly increased (P = 0.05). SDS-polyacrylamide gel electrophoresis performed on bone biopsies, which were pretreated with SDS, resulted in a double band of 39,000 D molecular weight in all panosteitis-affected dogs. Similar studies in control dogs resulted in a single band in this region. Attempts at amino acid sequencing from the N-terminal of the proteins in this double band region were unsuccessful. A chemical interference at the N-terminal end of these proteins was suspected. The composition of this double band is as yet unknown. The etiology of panosteitis could therefore not be definitively verified. However, it does appear that protein- or amino acid metabolism is affected in dogs with panosteitis.
