Abstract:
To study the mechanism and influence of pneumonia on myocardium in D-galactose(D-gal) treated mice, 36 normal male NIH mice were randomly selected and pretreated with D-gal, and then they were divided into three groups, namely control group, the first day after pneumonia group, and the third day after pneumonia group. Another group of 36 mice were pretreated with normal saline to form a general control group. The result showed that in the D-gal prtreated pneumonia mice, the degeneration of myocardial mitochondria was more pronounced, the content of MDA in myocardium was increased, and the activity of SOD and the content of ATP in the myocardium were reduced. There was a positive correlation between the content of ATP and the activity of SOD, and there was a negative correlation between the content of ATP and MDA in the myocardium. These results suggusted that the myocardial lipid peroxidation in the D-gal treated mice increased the susceptibility to the damaging factors, such as pneumonia.
