Figure 3 Tc99m-MAA scanning images of the rat brain and lung. Panel A: representative rat from control group fed standard diet (see details in Method), showing a full distribution of Tc99m-MAA in the lung; Panel B: representative rat from the group fed standard diet plus intraperitoneal injection with lipopolysaccharide (LPS), showing slight radioactivity in the brain; Panel C: representative rat from the cirrhotic group fed a mixture of maize flour, lard, cholesterol, and alcohol plus intraperitoneal injection with carbon tetrachloride (CCl₄) oil solution for 8 wk, showing significant increased radioactivity in the brain; Panel D: representative rat from cirrhotic animals plus LPS injection, showing much increased radioactivity in the brain.
