Abstract
The isopotential mapping of the T wave in myocardial infarction was studied to find the characteristic abnormality. The negative area on the mapping at the deepest point of the negative T wave was located on the left precordial region or on the left precordial and lateral regions in cases with anterior or anterolateral infarction. In some cases with anterolateral or inferior infarction and in cases with high posterior infarction, an extensive negative area was found on the left back region. In cases with inferior infarction, the negative area was situated on the lower area of the precordial region and/or back region. The ischemic area (the area of the abnormal repolarization) was determined by studying the relation of the zero line of the maps in normal subjects and cases with myocardial infarction. Finally, a comparison between the direction of the maximum T vector and the location of the ischemic area was made.

Abstract
A specific and sensitive method for the simultaneous determination of bestatin and its major metabolite, p-hydroxybestatin in human serum has been developed by selected ion monitoring using the corresponding deuterated internal standards. The N-trifluoroacetamide-O-trimethylsilyl either derivatives of the trideuteromethyl esters of bestatin and p-hydroxybestatin were suitable for quantitation by selected ion monitoring. The determination limit of these compounds by the present method is 1 ng ml-1 in human serum.
