The fluorescent granular perithelium (FGP) of rats and humans under experimental and pathological conditions was examined with the electron microscope. The FGP incorporated high molecular-weight protein (ferritin) and carbon particles administered intraventricularly. In a case of spontaneous cerebral hemorrhage, the FGP was found to contain lipoidal products and minute fragmented cell debris. The FGP in a patient with lipidosis contained pale inclusion bodies. In aged individuals, the inclusion bodies formed irregular larger aggregates.

Ouchterlony double immunodiffusion clearly demonstrated absence of ferritin, the principal iron storage protein, in spleen and/or liver extracts from nine patients with Niemann-Pick disease type C (NPC). The patients died from different clinical forms of this disease of still unknown etiology. The absence of ferritin immunoreactivity was shown using two different antisera raised in rabbits against ferritin from human spleen or liver, organs which predominantly contain light chain subunits (L-ferritin). A diagnostic double immunodiffusion assay of ferritin is, therefore, feasible with small amounts of NPC liver tissue, e.g., needle biopsy specimens. Furthermore, SDS-polyacrylamide gel electrophoresis after Coomassie blue staining revealed an almost complete absence of the L-ferritin protein band in crude spleen heat extracts from two NPC patients. The absence of visceral ferritin in all nine patients studied is suggestive of a biochemical abnormality that is as characteristic as the known impairment of cellular trafficking of LDL-derived cholesterol in this complex lysosomal storage disorder. According to recent data a relationship exists between ferritin-dependent lipid peroxidation and oxidative modification of LDL. We suggest that deficiency of the antioxidant ferritin-whatever the nature of this deficiency might be-could lead to uncontrolled LDL oxidation with subsequent multisubstrate lipidosis in NPC disease.

The hepatic lipidosis (HL) in fattening turkeys is a disease has been known for a long time, but the cause and pathogenesis is still not clarified. A recent study reported unexplained high levels of iron in liver tissue of fattening turkeys suffering from HL. In this study, the iron status, possible infectious or inflammatory influences in form of an acute phase reaction and the analysis of fatty acid pattern in liver tissue of turkeys affected by HL were examined. Three cases of HL on three different fattening turkey farms were investigated during the outbreak of the disease. Clinically affected and non-affected animals were subjected to a pathological examination, where the diagnosis HL or non-affected was made. In total, 70 birds were examined (40 with HL, 30 without HL) and blood and liver samples were taken. Additionally, samples from 15 slaughtered birds were taken as a further control group. In liver tissue, the iron content and the content of long-chain fatty acids were determined; in blood samples, ferritin and transferrin were measured. The iron content in liver tissue was more than three times higher for animals with HL than among non-affected animals and the control group. The transferrin levels were lowest for animals with HL, highest in the control group and in between for non-affected animals. The fatty acid pattern in liver tissue of affected animals indicated a shift from polyunsaturated fatty acids to saturated fatty acids and monounsaturated fatty acids compared to the control group and the non-affected animals. Overall, the non-affected animals of a flock affected by HL were similar to the healthy animals of the abattoir. The low acute phase protein levels for animals with HL together with high iron contents could indicate a previous malnutrition/starvation period and/or severe liver damage for those animals suffering from HL.
