Abstract

The concentrations of 8 trace metals in 15 discrete anatomic sites of 11 beef hearts have been determined by emission spectrometry. The metals determined were copper, aluminum, barium cesium, tin, strontium, lead, and molybdenum. Anatomic sites samples included aorta, main pulmonary artery, tricuspid valve, mitral valve, right and left coronary arteries, os cordis, right atrium, left atrial appendage, right and left ventricles (free wall), left ventricle-papillary muscle, interventricular septum, crista supraventricularis, and left bundle branch. Statistical analysis of the data incorporated a multivariate analysis of variance and a Duncan analysis. The results showed that many tissues of the beef cardiovascular system have distinctive trace metal compositions.

摘要

通过发射光谱法测定了11个牛心脏15个离散解剖部位中8种痕量金属的浓度。所测定的金属有铜、铝、钡、铯、锡、锶、铅和钼。解剖部位样本包括主动脉、主肺动脉、三尖瓣、二尖瓣、右冠状动脉和左冠状动脉、心骨、右心房、左心耳、右心室和左心室（游离壁）、左心室乳头肌、室间隔、室上嵴和左束支。数据的统计分析采用了多变量方差分析和邓肯分析。结果表明，牛心血管系统的许多组织具有独特的痕量金属组成。
