Abstract
Objective: This study was performed to analyze the singledose toxicity of Aconitum kusnezoffii Reichb. pharmacopuncture (AKRP).
Methods: All experiments were conducted at the Korea Testing & Research Institute (KTRI), an institute authorized to perform non-clinical studies, under the regulations of Good Laboratory Practice (GLP). Twenty (20) Sprague-Dawley rats were chosen for the pilot study. The animals were divided into four groups of five animals per group: group 1 (G1) being the control group with each animal receiving an injection of 0.3 ml of saline and groups 2, 3, and 4 (G2, G3, and G4) being the experimental groups with each animal receiving an injection of 0.1, 0.2 or 0.3 ml of AKRP, respectively. This study was conducted with the approval of the Institutional Animal Ethics Committee.
Results: No deaths occurred in any of the 4 groups, and the LD50 of AKRP administered via IV was higher than 1.77 ml/kg. Some changes in the weights of the male rates were observed between the control group and the experimental groups, but no significant differences were noted in the weights of the female rats. To check for abnormalities in organs and tissues, we stained representative sections of each specified organ with Hematoxylin & Eosin for light microscopic examination. The results showed no significant differences in any of the organs or tissues.|Conclusions: The above findings suggest that Aconitum kusnezoffii Reichb. pharmacopuncture is a relatively safe treatment. Further studies on the subject should be conducted to yield more concrete evidence.
