Immunohistochemical analysis of TNFα expression. (A) Representative images for TNFα expressions in the jejunal mucosae of control (A1), donor (A2), and recipient (A3).

<p>The brown immunostainings in the cells are TNFα. TNFα is located in the monocytes of intestinal mucosa, and there are not the expressions of TNFα in both villous and cryptal epithelial cells of intestinal mucosa. (B) Expression levels of TNFα in the jejunal mucosae of control, donor, and recipient. The results are expressed as optical density (arbitrary units). Values are mean ± SEM and n = 6 in each series. The expression level of TNFα in the jejunal mucosa of donor was higher markedly than that in control, but there was no significant difference between the expression levels of TNFα in the jejunal mucosae of recipient and control. ***<i>P</i><0.001, ^#<i>P</i>>0.05.
