Twenty-four hours after the last oral administration, the blood were obtained and used for testing adrenocorticotrophic hormone, cyclic adenosine monophosphate, cyclic guanosine monophosphate, glucose, cholesterol, alanine aminotransferase, urea nitrogen. Results Before taking medicine, model rats' cAMP/cGMP and ACTH were lower than normal rats', and they showed a trend of rise with adding dose. Before taking medicine, model rats' GLU was lower than normal rats'. With adding dose, model rats' GLU increased, however, normal rats' GLU reduced. When taken medium dose white prepared lateral root of aconite, model rats' CHO was higher than normal rats'. Taking medicine made both groups ALT rise, but normal rats' went up more quickly than model rats'. Model rats' BUN was higher than normal rats', and taking low dose or little dose medicine could lead to incline of reduction.
