  2. TAG, triacylglycerols; PL, phospholipids; ES, esters of sterols; tr, traces less than 0.1%. Asterisks indicate significant differences of fatty acid contents between rats from experimental group and corresponding control group: *for P < 0.05; **for P < 0.01; ***for P < 0.001. The numbers in boldface after the slash indicate the change of the value for the experimental group relative to that of the control group in the number of times. The arrow indicates that the value decreased. The arrow indicates that the value increased.
