The measurements of transaminases levels at 1 d, 3 d, 5 d, 7 d, 22 d, 44 d, and 46 d after prolonged and repeated oral administration of PMR: oral administration of PMR to rats for 1–7 d, 1 d after 2 w stop (interval), 1–3 d for 3 w stop, and 37 d for transaminases level during oral administration interval $(\stackrel{-}{x}\pm s,\hspace{0.17em}\hspace{0.17em}n=5)$. (a) and (b) for ALT level. (c) and (d) for AST level. ^∗Significant difference compared with other groups, P < 0.05. ^∗∗Extremely significant difference compared with other groups, P < 0.01.
