Compared to the control animals, the rats treated with AC showed increased levels of citrate, 2-oxoglutarate and cis -aconitate, and decreased levels of hippurate and phenylacetylglycine in the urine. Such metabolic changes may have reflected, respectively, the changes in body energy metabolism and in the metabolism of intestinal flora in response to AC treatment.

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.
