Effects of walnut oil on the expression of F4/80 in liver tissue of mice. A, Identification of F4/80 expression in liver by immunofluorescence (400× magnification; F4/80 staining, red and nuclear staining, blue); B, The F4/80 positive cells rate in liver.

Note: Data are presented as averaged expression levels and standard deviation of three repeats. Different uppercase letters (A, B, C, D) and lowercase letters (a, b, c, d) compared between different groups indicate the significant difference with p < 0.01 and p < 0.05, respectively. The same letters compared between different groups indicate no significant difference (p > 0.05). The same below.

For details of groups, see Table II.
