MELO, Gustavo Barreto de et al. Effect of omeprazole and pantoprazole on liver regeneration after partial hepatectomy in rats. Acta Cir. Bras. [online]. 2003, vol.18, n.6, pp.518-526. ISSN 0102-8650.

PURPOSE: To assess the effects of omeprazole and pantoprazole on liver regeneration after partial hepatectomy. METHODS: Fifty eight male Wistar rats were divided into 4 groups: SHAM, HP, PANTO and OMEP Groups. They were submitted to 67% partial hepatectomy (HP, PANTO and OMEP Groups) or laparotomy (SHAM Group). Their livers were removed 32 and 56 hours after the operation. Then, the animals were sacrificed. In all groups, the substances (saline solution, omeprazole and pantoprazole) were injected once daily from the moment they were operated on until the time of sacrifice. RESULTS: In SHAM Group the mitotic index was not significant. Thirty two hours after hepatectomy, the mitosis index was 1.2 ± 1.09 in HP Group, 1.2 ± 1.6 in OMEP Group and 2.6 ± 3.2 in PANTO Group. Concerning the 56-hour analysis, the values were 1.6 ± 0.89 in HP Group, 2 ± 1.8 in OMEP Group and 2.6 ± 0.54 in PANTO Group. These results were not statistically significant. CONCLUSION: Omeprazole and pantoprazole, proton pump inhibitors (H+, K+-ATPase), do not cause any change on liver regeneration 32 and 56 hours after 67% partial hepatectomy in rats.
