(英) Measurements of adenylate nucleotides (i.e., ATP, ADP) are used extensively to monitor energy stasis in broad range of cell types and tissues. For applications involving mammalian and other animal tissue, ATP are commonly extracted with chaotropic reagents particularly trichloroacetic acid (TCA) and perchloric acid (PCA). Physical methods for disintegration (boiling, sonic disintegration) have also used. As expected, these methods are suitable for measurements of cellular ATP, however these methods are inappropriate for histionic ATP because of the inefficiency of nucleotides extraction. Consequently, we have developed an integrated kit that includes software programs measuring tissue or total blood ATP. As the first step, we have evaluated the clinically usefulness of this system for determining blood ATP levels in patients with acute disease such as influenza-associated encephalopathy. It was found that various patients with severe disease have decreased blood ATP levels. It can be anticipated that in the abovementioned disease states, ATP measurement will become a valuable clinical parameter of great potential clinical importance.
