The histopathology of fatty liver and kidney syndrome in chicks.
Studies of the general histopathology of the fatty liver and kidney syndrome in chickens have shown abnormal accumulations of the lipid in a variety of organs but no degenerative or inflammatory reactions. Lipid was found in some skeletal muscles, alimentary tract, autonomic ganglia, central nervous system and pineal gland as well as in the liver, kidney and heart. Small amounts of lipid were sometimes seen in the exocrine pancreas, adrenal medulla and epithelium of the thyroid follicles. Lipid deposits in the liver were primarily associated with the hepatic structural unit. The glycogen content of the hepatic cell was reduced. The lipid-metabolising gastrocnemius muscle contained abnormal amounts of lipid but this did not apply to the carbohydrate-metabolising pectoralis major muscle. The thymus did not contain excessive lipid but was significantly smaller in affected than in control birds of similar ages. There was loss of tinctorial distinction between the cortex and medulla of the adrenal gland associated with decreased basophilia of the latter region. Many of these morphological changes can be correlated with previously reported biochemical findings and they are discussed in relation to the hyperlipaemia and hypoglycaemia which characterise the disease.
