A method was developed for measuring the concentration of lipid peroxidation products in rabbit brain, heart, lung, liver, and kidney tissue. Specimens were homogenized in cold buffer, acidified, and heated to near boiling in the presence of thiobarbituric acid in order to form the malondialdehyde-thiobarbiturate adduct. After centrifugation, the(More)
Potato dextrose agar (PDA) is one of the most commonly used media for the isolation and cultivation of fungi, with morphological features and pigmentation in culture often being important for identification of cultures. Cultivation of various fungi on different brands and batches of powdered (commercial) potato dextrose media revealed deficient pigmentation(More)
We report two methods for determining aluminum concentrations in blood. Method 1, proposed for routine monitoring of patients with chronic renal failure, includes a collection procedure that can be adopted by any renal dialysis unit, with a minimum of sample contamination. Plasma samples are diluted fourfold with HNO3/Triton X-100 matrix modifier. Method 2(More)

The intracisternal administration of aluminum maltolate to New Zealand white rabbits produces a reproducible neurofibrillary degeneration which is significantly reversed by desferrioxamine treatment. Quantitative analysis of brain and spinal cord tissue demonstrates that the aluminum deposition is higher close to the injection site than at locations further(More)
We describe a simple and convenient method for processing small amounts of tissue samples for trace-metal measurements by atomic absorption spectrometry, by use of a modified Parr microwave digestion bomb. Digestion proceeds rapidly (less than or equal to 90 s) in a sealed Teflon-lined vessel that eliminates contamination or loss from volatilization. Small(More)
