title: Influence of doxycycline on the epiphyseal plate cartilage of the rats in experimental osteoarthrosis, induced by iodoacetate.
abstract: In 36 Wistar rats with the iodoacetate-induced experimental osteoarthrosis (OA), effects of doxycycline, given orally, were determined on histochemical reactions of glycosaminoglycans (GAG) in the epiphyseal plate cartilage. The epiphyseal plate of rats with OA was reduced in height (especially the proliferative zone), cell columns were disorganized, many chondrocytes were irregular and polygonal, their nuclei were pycnotic, the intensity of GAG staining was irregular and predominantly reduced, which can be interpreted as signs of degeneration. A concomitant administration of doxycycline in the second group of rats prevented, to some extent, the negative effects of iodoacetate on chondrocytes and led to a more pronounced intensity of GAG reactions in the matrix of the epiphyseal plate.
