Objectives To evaluate Shinbaro Pharmacopuncture safety through analysis of potential single-dose intramuscular toxicity of Sinbaro Pharmacopucture in SD rats and Beagle dogs. Methods Single-dose intramuscular toxicity of Shinbaro Pharmacopuncture was assessed in accordance with Korea Food and Drug Administration Guidelines for toxicity testing of Medicinal Products. The SD rats were treated intramuscularly with Shinbaro Pharmacopuncture at doses of 0, 4.6, 9.2, and 18.5 mg/kg, respectively. The Beagle dogs were treated intramuscularly with Shinbaro Pharmacopuncture at doses of 2.3, and 4.6 mg/kg, respectively, and after 3 days, the procedure was repeated a second time at doses of 0.6, and 1.2 mg/kg, respectively, for toxicity testing. Mortality, change in body weight, and necropsy findings were examined for the study period. Results There were no mortalities, general symptoms, or body weight changes in the SD rats. While pyelectasis of the left kidney was observed in a male rat in the 4.6 mg/kg administration group, natural occurrence is common, and does not appear to be related with the test substance. No mortalities were observed in the Beagle dogs. In assessment of general symptoms, a female dog in the 9.2 mg/kg group displayed body weight decrease due to leftover food, but the change in body weight was within the normal range seen at 6~7 months, and the necropsy findings were not significant. The toxicity of the test substance appears to be minimal. Conclusions The results suggest that the lethal dose 50 (LD50) and approximate lethaldose (ALD) value in single intramuscular administration of Shinbaro Pharmacopuncture in SD rats and Beagle dogs are higher than 18.5 mg/kg.

Objectives To assess the safety of Shinbaro3 Pharmacopuncture by analyzing the potential single-dose intramuscular toxicity of Shinbaro3 Pharmacopuncture at various dose levels in SD (Spraque-Dawley) rats and Beagle dogs. Methods For evaluation of single-dose intramuscular toxicity of Shinbaro3 Pharmacopuncture, 40 SD rats (20 male and 20 famale) and 4 Beagle dogs (2 male and 2 female) were used. The rats were divided in four groups of 10 each, and treated intramuscularly with Shinbaro3 Pharmacopuncture at doses of 0.3, 0.6 and 1.2 mg/kg in distilled water, and distilled water as a vehicle control group, respectively. The Beagle dogs were divided into two groups of 2 each, and treated intramuscularly with Shinbaro3 Pharmacopuncture at doses of 0.15, and 0.3 mg/kg in distilled water, respectively, and signs of toxicity were observed. After a wash-out period of 3 days, the procedure was repeated with Shinbaro3 Pharmacopuncture at doses of 0.6, and 1.2 mg/kg in distilled water, respectively. Mortality, body weight changes, and necropsy findings were examined during the study period. Results There were no mortalities in either the SD rats or Beagle dogs. There were also no significant differences in adverse effects, body weight, or necropsy findings between the Shinbaro3 Pharmacopuncture and control groups. Conclusions There results suggest that the lethal dose 50 (LD50) and approximate lethal dose (ALD) value of the test substance Shinbaro3 Pharmacopuncture are higher than 1.2 mg/kg in SD rats and Beagle dogs. , 그
