Studies on the Kinetic Properties of Cells of Aquatic Animals During Death with 31P NMR

Abstract

Abstract: Cell death manner is related to the contents of intra-cell energy substances. The rate constants and the half life-time of ATP, phosphocreatine (PCr) anDInorganic phosphorus (P_i) in different cells of eel and crucian during their death have been determined with ³¹P NMR. It has been found that there are differences in rate constants and change rule of these energy substances for different animals and different cells in the same animal from this study. The decreasing order of the half life time is: muscle of eel>brain of eel>muscle of crucian for ATP; brain of eel≈muscle of eel>muscle of crucian for PCr. These results are very vital to understanding the concerned change pattern of energy substances and the speed of cell death.

Key words: P-NMR, Cell death, ATP, Dynamics
