| Popis: |
The progressive changes in pH, lactate content, and light and electron microscopic appearances were studied in dog myocardium undergoing a 6-hour period of autolysis in vitro at 37 degrees C. and at room temperature. At 37 degrees C. there was a rapid cumulative fall in pH during the 1st hour after excision of the heart and a corresponding increase in lactate content, but little additional change in either subsequently. The nature and sequence of the morphologic alterations at this temperature were generally similar to those which occur in ischemic myocardium in vivo. At room temperature, a much slower cumulative decrease in pH and increase in lactate content took place throughout the whole period of investigation and was paralleled by a slower rate of development of morphologic change. |
