 note = {application/pdf, Broken-back syndrome occurred among the channel catfish,Ictalurus punctatus at a low incidence in a commercial catfish pond in the United States in 1982. One of the fish suffering from broken-back syndrome was histopathologically studied. The fish showed kyphosis of the posterior abdominal vertebrae accompanied with hemorrhage. In histopathological examinations,the fractured vertebrae were found to be highly osteoporotic,degenerated and accompanied with proliferation of chondrocytes. Its periousteum was composed of thin and partly hyalinized collagen fibers,and proliferated chondrocytes,indicating impairment of collagen synthesis. The systemic connecitve tissues were consisted by defective collagen fibers.The pancreas,splenic pulps and hematopoietic tissue showed numerical atrophy.These histopathological signs resembled those of broken-back syndrome that was experimentally evoked with ascorbic acid-free diets in channel catfish.},
