title: Evidence for a lesion in carbohydrate metabolism in fatty liver and kidney syndrome in chicks.
abstract: Liver and kidney slices from chicks affected with fatty liver and kidney syndrome (FLKS) were incubated in vitro with a variety of non-carbohydrate precursors and their ability to form glucose was studied. The results show that the affected liver was unable to form significant quantities of glucose from the precursors (gluconeogenesis). Glycogen breakdown was also drastically reduced because the tissue was almost devoid of this carbohydrate store. Blood chemistry revealed no evidence of overall liver malfunction but reflected the consequences of lack of gluconeogenesis. In contrast, kidney gluconeogenic activity was significantly higher than in the controls, suggesting an attempt by this organ to offset the reduced hepatic capability. Attempts to restore activity in vitro were made by adding known cofactors of gluconeogenesis. Asmall but significant improvement resulted from addition of biotin to liver slices.
