Figure 2. The secretory activities of amylase (a.) and lipase (b.) in the basal and in the CCK-stimulated states (10 pmol/L) over the entire 90-min period in pancreatic lobules isolated from control rats and HFLCD fed rats. Each bar represents the mean±SE of data obtained from 13 experiments. The secretory amylase activities in thebasal and in the CCK-stimulated states in HF-LCD fed rats were significantly lower than those in control rats. The secretory lipase activities in the basal and in the CCK-stimulated states were not significantly changed by HF-LCD feeding.
