The cyclic variation of integrated backscatter and echo intensity of three different myocardial regions perfused by left anterior descending coronary artery, left circumflex coronary artery and right coronary artery (on the frozen frame of parasternal short-axis image,those position were approximately at the 12, 4 and 8 o'clock direction to the center of the left ventricle, respectively) were measured with HP-5500 ultrasonic system and DFY ultrasonographic quantitative analysis system.

在35例急性心肌梗死患者发病2周内，用HP-5500型超声诊断仪和DFY型超声图像定量分析诊断仪，在胸骨旁左室乳头肌短轴切面，分别测量冠状动脉左前降支、左回旋支和右冠状动脉支配区域心肌组织(分别相当于左室乳头肌短轴切面上12、4、8点的位置)的IB和EI心动周期变化幅度值，以CVIB和CVEI值≤同一切面三个不同部位中最高值的1/2作为诊断心肌梗死的标准，部分病例与冠脉造影结果对比。

In conclusion,lacking for choline and methionine led to decrease growth performance decrease and tibia with short disease; Basal diet supplemented with 750 ppm – 1250 ppm Cholin improved Growth performance ,and prevented the occurrence of perosis. Higher dietary choline can alleviate the adverse effects of methionine and choline deficiency.

总结而论，缺乏胆碱与甲硫胺酸会导致生长性能下降和胫骨粗短症；饲粮中添加750~1250 ppm之胆碱可以改善生长性能及防止胫骨粗短症的发生；饲粮添加高剂量的胆碱，可以缓和甲硫胺酸和胆碱缺乏之不良影响。
