2. FIG. 1
Photomicrograph of rat liver undergoing acute cellular rejection. There is a significant infiltration of inflammatory cells within the portal triads and sinusoids (a). Some tunneling of the infiltrate beneath the portal vein endothelium is also observed (b). (Hematoxylin and eosin; ×64).

3. FIG. 2
Photomicrograph of rat liver treated with subthreshold doses of FK-506. Treatment with a suboptimal dose of FK-506 is unable to prevent acute cellular rejection. As in Fig. 1, a significant inflammatory infiltrate is present within the portal triads and sinusoids (a). Some degree of hepatocellular necrosis is also evident (b). (Hematoxylin and eosin; ×64).

4. FIG. 3
Photomicrograph of rat liver treated with 30,000 U/kg of PEG-SOD. Treatment with 30,000 U/kg of PEG-SOD alone resulted in a reduction in the cellular infiltration into the sinusoids as compared with Figs. 1 and 2. However, treatment with PEG-SOD alone was unable to completely prevent acute cellular rejection (a).

5. FIG. 4
Micrograph of rat liver treated with FK 0.04 mg/kg and 30,000 U/kg of PEG-SOD. Treatment with a combination of PEG-SOD and suboptimal doses of FK-506 results in a significant reduction of cellular infiltration into the portal triads and sinusoids (a). Hepatocellular architecture is better preserved. (Hematoxylin and eosin; × 64).
