Result At 5 and 25 mgkg^(-1), the total respiratory rate had a similar trend with tricarboxylic acid cycle and pentose phosphate pathway, T1, and T2 were higher than the control on the 1st day and then declined three days late but they had a recover on the last day. Embden-Meyer-hot-Parnas pathway had a declined trend forever. The respiratory rate of the total and three pathways were decreased under 125 mgkg^(-1). The enzyme activity of pyrophosphate-dependent phosphofructokinase, glucose-6-phosphate dehydrogenase (G-6-PDH) and malate dehydrogenase were similar to relative respiratory pathway.
