Mitochondrial dysfunction in amyotrophic lateral sclerosis - a valid pharmacological target?

abstract：:1 A simple double-isotope assay for phospholipase A2 activity of perfused organs is described; Guinea-pig lungs perfused through the pulmonary circulation exhibit a low background enzyme activity. This activity is blocked by dexamethasone, betamethasone and hydrocortisone, mepacrine, procaine or chlorpromazine. Aspiri...
