Table 3 Myeloperoxidase (MPO) activity in the jejunum segment from inducible nitric oxide synthase knock-out mice (iNOS-/-) and C57BL/6 wild-type animals (iNOS+/+) submitted to intestinal mucositis

From: Role of inducible nitric oxide synthase pathway on methotrexate-induced intestinal mucositis in rodents

  1. Intestinal mucositis was induced by subcutaneous administration of MTX. After sacrifice, on the 5th day, a sample of the jejunum segment was harvested for MPO activity assay. *p < 0.05 represents statistical differences compared to iNOS+/+/control group. The number of animals in each group was at least four. Data were analyzed by using analysis of variance (ANOVA) and Bonferroni tests.
