The role of platelet-activating factor (PAF) in ischemic acute renal failure was evaluated by administering an oral PAF antagonist (Ro-24-4736) to rats prior to or after interruption of blood flow to both kidneys for 30 min. In animals treated with t

Two enzyme systems which catalyze polyprenol synthesis from Δ3-isopentenyl pyrophosphate and farnesyl pyrophosphate have been extracted from Salmonella newington. One system, which is soluble, yields products of chain length shorter than the 55-carb

L-Dopa, an intermediate in the biosynthesis of catecholamines, is now widely used in the treatment of parkinsonism. A number of clinical observations suggested that L-dopa may induce changes in its own metabolism during the course of therapy. In the

Publisher Summary This chapter discusses characteristics of DOPA decarboxylase. DOPA decarboxylase, which catalyses the conversion of L-dopa to dopamine, was the first of the catecholamine biosynthetic enzymes to be discovered. In a study, the dopa d
