The effect of tacrolimus (FK506) on peptic ulcer was evaluated using pyloric ligation (PL) model in rats. Tacrolimus was administered orally at different doses (1, 2 and 3 mg/kg) and it showed a gastric ulcer healing effect in a dose dependent manner. Gastric volume, total and free acidity and ulcerative index parameters were reduced in the tacrolimus treated rats as compared to pyloric ligated rats. The higher dose (3 mg/kg) treated group produced significant results similar to that of the ranitidine (50 mg/kg) treated group. Pretreatment with tacrolimus also produced significant (p<0.05) reduction in TBARS, total calcium, TNF-alpha, IL-8 and MPO whereas it showed an increase in GSH level at higher dose. The anti-secretory and anti-ulcerative effect of tacrolimus may be due to immunosuppressive actions by inhibition of calcineurin and the oxidative pathway. It can be concluded that tacrolimus can play an important role in the treatment of peptic ulcer disorder to improve the quality of life.

Purposes; FK506 (strong immunosuppressive agent) was investigated experimentally whether to protect the hepatic IRI. Methods; Warm ischemic experiment using pigs and rats were performed and examined whether FK506 is effective. Results; The results obtained are as follows. 1. Warm ischemia allowed time of the pigs without FK506 was 150 minutes, but as for that of FK506 group, the extension of 30 minutes was got in 180 minutes. 2. Biliary excretion rate of BSP after reperfusion were better in the group of 180 minutes ischemia with FK506 than in without FK506 group. 3. Chemiluminescence intensity in the peripheral neutrophils and adhered and infiltrated leukocytes in the liver were suppressed markedly by FK506. 4. The vascular endothelium with the scanning electron microscope was relatively preserved in the FK506 group comparing to the placebo group on 30 minutes after reperfusion. 5. Stress gastric ulcer was controlled and myeloperoxidase activity in the gastric mucosa was suppressed by FK506. Conclusion; Based on the results of theses experiments, it was suggested that FK506 has a protective effect on IRI by suppressing: the impairment of sinusoidal endothelial cells; the activation of KCs; the disturbance of micro-circulation; oxidative stress; inflammation; and the accumulation of leukocytes.
