摘要
1. 1. Studies were conducted to determine if the biochemical alterations of sarcoplasmic reticulum fragments produced by diethyl ether or thymol treatment were related to the membrane ultrastructure. 2. 2. Concentrations of diethyl ether or thymol that abolished Ca2+-accumulating ability but did not reduce the Ca2+-activated ATPase activity caused the formation of transparent patches on the surface of negatively stained vesicles. 3. 3. Higher concentrations of diethyl ether or thymol caused a decrease in the Ca2+-activated ATPase activity, an apparent loss of the 40- A ̊ subunits and an increased irregularity in the vesicle surface structure. The vesicle shapes observed in sectioned preparations were also altered. © 1969.
