Figure 5.
Effect of disease on tissue acetylcholine. Lacrimal (LG) and submandibular (SG) glands were removed from 18-week-old MRL/lpr (lpr) and MRL/+ (+/+) mice and the concentration of acetylcholine in tissue homogenates was measured. Data are means ±SEM, n = 3 to 5. *Significant difference from submandibular glands of MRL/+ mice.
