Abstract/OtherAbstract:
Cardiac lymph was obtained from 12 normal dogs (group 1) for two consecutive 2-h control periods and from 7 dogs (group 2) for 2 h before and 2 h after occlusion of the circumflex branch of the left coronary artery. Lymph composition was studied with reference to pH, red blood cell (RBC) concentration, total protein content, potassium and sodium ion concentrations, and creatine phosphokinase (CPK) and acid phosphatase enzyme activities. No significant difference was noted in any variable between the two groups during the firts 2-h period. In group 1, no significant changes occurred in any variable as a result of the passage of time alone. In group 2, 2 h of myocardial ischemia produced increases of 53.3 plus or minus 5.1% in lymph flow, 67 plus or minus 5% in protein content, and 418 plus or minus 27% in the RBC concentration, suggesting increased blood capillary permeability. Lactate rose 120.5 plus or minus 27%, potassium concentration increased 16.9 plus or minus 2.4%, acid phosphatase increased 30 plus or minus 3%, and CPK rose 61.6 pluse or minus 10.9%, suggesting ischemic injury of myocardial cells. These changes in lymph were statistically significant (P LESS THAN 0.05) and reflect both capillary and myocardial cell abnormalities.
