Chronic administration of chlorphentermine to rats resulted in a reduction of body weight compared to a normal control group. The weight of the heart, liver, kidney, and spleen was less in the treated group while the weight of the lungs was increased significantly. There was no change in the ratio of right ventricular to left ventricular weight in the rats treated with chlorphentermine, support...

Combined recordings of the electroretinogram (ERG) and the cortical visual evoked response (VER) have been made together with the electroencephalogram (EEG) in 16 children suffering from a `late infantile' form of `neuronal lipidosis'. The ERG was not usually recordable, in keeping with a gross loss of function of the retinal receptor elements. However, in all the 16 children, at whatever stage...

We investigated peroxisomal alterations in mice treated with different doses of Lorenzo's Oil (a therapy for X-linked adrenoleukodystrophy patients) for up to 100 days. Hepatic erucic acid levels were already significantly increased 2.2-fold and 2.6-fold in mice treated with 10% and 20% Lorenzo's Oil for 21 days, respectively. No lipidosis was found in liver, myocardium and kidney of any of the...

Abnormalities of fatty acid metabolism are recognized to play a significant role in human disease, but the mechanisms remain poorly understood. Long-chain acyl-CoA dehydrogenase (LCAD) catalyzes the initial step in mitochondrial fatty acid oxidation (FAO). We produced a mouse model of LCAD deficiency with severely impaired FAO. Matings between LCAD +/- mice yielded an abnormally low number of L...

BackgroundLipoprotein lipase (LPL) is an important enzyme in lipid metabolism, individuals with LPL variants could present type I hyperlipoproteinemia, lipemia retinalis, hepatosplenomegaly, and pancreatitis. To date, there are no reports of renal lipidosis induced by hyperlipoproteinemia due to mutation.MethodsRenal biopsy was conducted confirm the etiological factor nephrotic syndrome a 44-ye...

Retinal ultrastructure was examined at various intervals following a single intravitreal injection of 100-4,000 micrograms of gentamicin in rabbit eyes. Three days after injections of 100-500 micrograms, numerous abnormal lamellar lysosomal inclusions were observed in the retinal pigment epithelium (RPE) and in macrophages in the subretinal space. These changes were typical of drug-induced lipi...

Intermediate (8--9 nm) filaments of human central nervous system astrocytes were isolated from the gliosed white matter of cases of adrenoleukodystrophy (ALD). This hereditary lipidosis is characterized pathologically by demyelination, loss of axons, and replacement of the white matter of the caudal cerebrum by a glial scar. Glial filaments were composed largely of a single protein component wi...

A case of acquired skin fragility syndrome associated with hepatic disease in a 9-year-old, spayed female, domestic shorthair cat is described. The cat was admitted to the veterinary hospital of the University of São Paulo (Brazil) with a 6-week history of vomiting, inappetence and weight loss. Remarkable signs were weakness, lethargy and profound jaundice that had been present for 10 days acco...
