Protective Role of N-Acetylcysteine on Isoprenaline-Induced Myocardial Injury: Histological, Immunohistochemical and Morphometric Study.

Several researchers studied the protective effect of the N-acetylcysteine (NAC) when it was given before the induction of myocardial infarction (MI). Other researchers studied such protective effect when it was before done and after done of the MI. The missing data are the comparison between the protective effect of NAC before myocardial injury with its protective effect both before and after myocardial injury.
