Abstract
1. The neuronal ceroid-lipofuscinoses is a group of diseases characterized by a widespread accumulation in the body of pigments believed to be end-products of lipid-peroxidation damaged organelles. It was recently shown that cerebrospinal fluid from patients with infantile and juvenile neuronal ceroid-lipofuscinosis were less protective against superoxide radical-induced hydroxyl radical formation compared with controls [3]. 2. The content of superoxide dismutase isoenzymes in cerebrospinal fluid and in plasma from patients with different forms of neuronal ceroid-lipofuscinosis was analysed. No significant difference from controls could be demonstrated in samples from patients with juvenile neuronal ceroid-lipofuscinosis. The few samples from patients with infantile and late infantile neuronal ceroid-lipofuscinosis analysed all fell within the range defined by the controls.
