Development in body weight after tMCAo or sham. 2A shows the development in the mean body weight after surgery for all four groups. Note the rapid decrease in body weight within the first four days where all animals lost around 15% of their preoperative body weight. black ■: sham + saline; red ■: sham + parecoxib; black ●: tMCAo + saline; and red ●: tMCAo + parecoxib. 2B depicts the DWI of an animal obtained 24 hours (1) and one week after surgery (2). Although this animal apparently had no ischemic brain injury, there is a clear signal enhancement of the temporal muscle (white arrow) on the right side (B1). The signal changes are consistent with severe ischemia due to ECA ligation. Note the involution of the temporal muscle (white arrow) after one week (B2).
