Abstract:
This study was aimed to observe influence of disease/syndrome on the toxicity and effect of aconite roots, in order to reveal relationship among disease/syndrome, toxicity and effect. The mice model of cold syn-drome was establish by wind-cold stimulation. The pain model was established by intraperitioneal injection of glacial acetic acid. Then, LD50 and ED50 of analgesic effect were compared, as well as the therapeutic index (TI) of crude aconite roots. The rat model of cold syndrome was also established by wind-cold stimulation. And the rheumatoid arthritis (RA) model was established by intracutaneous injection of CII and CFA. TD50 of cardiac toxic-ity and arthroncus degree of prepared aconite roots were compared among the normal rats, RA rats, RA with wind-cold stimulation rats according to the recording of lead II ECG. The results showed that after wind-cold stimulation, mice and rats appeared with symptoms which were similar to Chinese medicine cold syndrome. Com-pared with normal mice, LD50 and TI increased, but ED50 decreased in the group of wind-cold stimulation after using powders of crude aconite roots. Compared with normal rats, TD50 of cardiac toxicity and arthroncus degree in-creased in groups of RA and RA with wind-cold stimulation after using prepared aconite roots. It was concluded that in the case of disease/syndrome state, the toxicity of aconite roots decreased, but its effect increased. It sug-gested that there is a significant correlation among disease/syndrome, toxicity and effect.
