title: Chicken erythrocyte membrane: lipid profile and enzymatic activity under lanthanum chloride and neodymium chloride administration.
abstract: Acute single dose (ip) administration of two rare earth elements like lanthanum chloride (250 mg/kg body wt) and neodymium chloride (200 mg/kg body wt) to chicks have been found to reduce the activity of certain erythrocyte membrane bound enzymes, viz. acetylcholinesterase, NADH dehydrogenase, Mg(2+)-ATPase, p-nitrophenyl phosphatase. Erythrocyte membrane bound glycosidases e.g. beta-D-glucosidase, beta-D-galactosidase and beta-D-glucuronidase were also reduced. Other components such as cholesterol and phospholipid residues were reduced but their ratio (cholesterol/phospholipid) remaining unchanged. Membrane sulfhydryl groups were also significantly inhibited by these rare earth elements.
