|Growing evidences from both animal experiments and clinical researches have shown that, L-arginine (L-Arg) has obvious effect on prevention for myocardium ischemia-reperfusion (IR) injury. To explore the effect of L-Arg on the function of myocardial mitochondria during IR, the parameters as follows: the respiratory function, Ca2+ concentration ([Ca2+]), malondialdehyde (MDA) concentration, superoxide Dismutase (SOD) activity and adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP) content, the total amount of AMP (TAN), energy charge (EC) intervention of mitochondria were dynamically observed basing on the ischemia-reperfusion (IR) injury model, which provided a theoretical support for the cardiac protection in perioperative period.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
