Fatty acid analysis of the plasma PL (phospholipid) fraction in patients with pneumonia, septicemia, RA and lupus. Both pneumonia and sepsis are more common elderly. All values are expressed as mean ± S. E. This data is taken form [106]. ** p < 0.001 compared to control; * p < 0.05 compared to control.
