  • Objectives : This study was conducted to analyze the single dose toxicity of Mecasin (Gami-Jakyak Gamcho buja Decoction) herbal acupuncture administered in the vein of Sprague-Dawley rats. Methods : All experiments were performed at the Medvill, an institution licensed to conduct nonclinical studies, under the Good Laboratory Practice (GLP) regulations. Sprague-Dawley rats were chosen in this pilot study. In the experiment, Sprague-Dawley rats were divided into four groups of five male and five female animals per group. Doses of Mecasin herbal acupuncture, at 0, 500, 1,000, and 2,000 mg/kg, were given to the experimental groups, and a dose of normal saline solution, at 2 ml/kg, was administered to the control group. Mecasin herb acupuncture and normal saline were injected into the vein at once, and we observed mortality, clinical signs, weights, and gross findings for 14 days after injection. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results : There is no death or abnormality in any of the four groups. All groups put on weights favorably. There are no significant gross findings in necropsy examinations. Conclusions : The above results showed that intravenous injection of 500-2,000 mg/kg of Mecasin herb acupuncture did not cause any changes in weight or, in the results of necropsy examinations, in mortalities. Therefore, the toxicity of Mecasin herb acupuncture was not confirmed, and the presumptive lethal dose of Mecasin herb acupuncture was higher than 2,000 mg/kg. The outcomes suggest that treatment with Mecasin herbal acupuncture is relatively safe. Further evaluations on this subject are needed to yield more concrete evidence.

  • Objectives : To evaluate the safety of multiple-dose intramuscular Shinbaro Pharmacopuncture in male and female Sprague-Dawley(SD) rats over a period of 4 weeks(12 sessions). Methods : In order to test the safety of multiple-dose intramuscular Shinbaro Pharmacopuncture we used 40 healthy male and female 6-week old SD rats(male weight 171.79~196.37 g, female weight 127.93~146.43 g). Shinbaro Pharmacopuncture was administered intramuscularly to male and female SD rats at doses of 4.6 (low dose group, n=10), 9.2 (moderate dose group, n=10), and 18.5 mg/kg(high dose group, n=10), respectively. General symptoms, body weight changes, blood tests, biochemical testing, necropsy, organ weight and histopathogical findings were examined over a 4-week period. Results : 1. No mortalities or adverse effects were caused by the investigational substance were observed during the study period. 2. There was no significant difference in body weight caused by the the investigational substance across all groups. 3. No significant between-group difference was found to be caused by the investigational substance in blood tests and biochemical testing. 4. No abnormalities were detected by a necropsy examination with the unaided eye at the macro level after treatment with the investigational substance. 5. Difference in organ weight between groups caused by the investigational substance was not found. 6. All groups did not exhibit pathological findings caused by the investigational substance in histopathogical examination. Conclusions : According to these results, Shinbaro Pharmacopuncture has no systemic or organ toxicity with multiple-dose intramuscular administrations in male and female SD rats over a 4-week period (12 sessions). These results imply that no adverse effects are observed at a level (NOAEL) of Shinbaro Pharmacopuncture of 18.5 mg/kg.

  • 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 ($LD_{50}$) 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: This study investigated the aconitine contents analysis of Buja extracts (raw material of Buja, hot water extract of Buja, and hot water extract of Sambu-tang) and the single oral dose toxicity of Sambu-tang-R in six-week-old Sprague-Dawley rats in order to compare the toxicity of Buja extracts.Methods: Aconitine content analysis is that Buja extracts were hold purity test. To detect single oral dose toxicity, six-week-old Sprague-Dawley rats were divided into two groups, a normal control group and a sambutang-R (2,000 mg/kg) group. For 14 days of treatment, clinical signs, body weight, clinical chemistry, necropsy, and histopathology were examined.Results: The aconitine contents of the Buja extracts were Buja-RH (0.1738%), Buja-RD (0.1746%), and Sambu-tang-R (0.0961%). There were no cases of death in either the control group or the experimental group. Nor was there any disorder to the clinical signs or any significant change in body weight in either group. There was no significant change of clinical chemistry or disorder of necropsy findings in either the control or the experimental group. And there was no difference in histopathological findings in comparing the control group with the experimental group.Conclusions: These results suggest that the aconitine content of the hot water extract of Buja was similar to the raw material of Buja, but the hot water extract of Sambu-tang had greatly decreased aconitine content. These results also suggest that a single oral lethal dose of Sambu-tang-R for Sprague-Dawley rats exceeds 2,000 mg/kg for both female and male rats.

  • This study was to investigate single and repeated-dose toxicities of Tensolin-$F^{(R)}$, an anti-wrinkle agent, in Sprague-Dawley (SD) rats or ICR mice. In single-dose oral toxicity study, the test materials were administered once by gavage to male and female SD rats at dose levels of 0 and 2,000 mg/kg. No dead animals and abnormal necropsy findings were found in control and Tensolin-$F^{(R)}$ treated group. Therefore, the approximate lethal dose of Tensolin-$F^{(R)}$ was considered to be higher than 2,000 mg/kg in rats. In the 4-week repeated oral toxicity study, the test material was administered once daily by gavage to male and female ICR mice at dose levels of 0, 25, 50 and 100 mg/kg/day for 4-weeks. In the results, no abnormality was observed in mortality, clinical findings, body weight changes, food and water consumptions, opthalmoscopic findings, necropsy findings, histopathological findings. In hematological analysis, there was a trend of increase in reticulocyte at male 25 mg/kg, although such changes were in normal ranges. On the other hand, there was a trend of decrease in hemoglobin at female 50, 100 mg/kg, such changes were in normal ranges. In addition, serum biochemical parameters including sodium, BUN and chloride increased at 25, 50 and 100 mg/kg. Relative organ weights of right testis, brain, lung and left epididymis were increased in 100 mg/kg groups of male rats in contrast to not change in female groups. However, these changes of relative organ weights, hematological and serum biochemical parameters were not accompanied with related signs such as histopathological changes or clinical findings. In conclusion, 4-week repeated oral dose of Tensolin-$F^{(R)}$ to ICR mice did not cause apparent toxicological change at the dose of 25, 50, 100 mg/kg body weight. Consequently the no-observed-adverse-effect level (NOAEL) for Tensolin-$F^{(R)}$ in ICR mice following gavage for at least 4-week is higher than 100 mg/kg/day.

  • Objectives: This experiment was conducted to examine the toxicity of Water soluble Carthmi-Flos herbal acupuncture (WCF) by administering a single intramuscular dose of WCF in 6-week-old, male and female Sprague-Dawley rats and to find the lethality dose for WCF. Methods: The experiment was conducted at Biotoxtech according to Good Laboratory Practices under a request by the Korean Pharmacopuncture Institute. This experiment was performed based on the testing standards of "Toxicity Test Standards for Drugs" by the Ministry of Food and Drug Safety. Subjects were divided into 4 groups: 1 control group in which normal saline was administered and 3 test groups in which 0.1, 0.5 or 1.0 mL of WCF was administered; a single intramuscular dose was injected into 5 males and 5 females in each group. General symptoms and body weights were observed/measured for 14 days after injection. At the end of the observation period, hematological and clinical chemistry tests were performed, followed by necropsy and histopathological examinations of the injected sections. Results: No mortalities were observed in any group. Also, symptoms, body weight, hematology, clinical chemistry and necropsy were not affected. However, histopathological examination of the injected part in one female in the 1.0-mL group showed infiltration of mononuclear cells and a multi-nucleated giant cell around eosinophilic material. Conclusion: Administration of single intramuscular doses of WCF in 3 groups of rats showed that the approximate lethal dose of WCF for all rats was in excess of 1.0 mL, as no mortalities were observed for injections up to and including 1.0 mL.

  • Objectives: This study was performed to evaluate the single-dose intravenous toxicity of Guseonwangdo-go glucose 20% pharmacopuncture. Methods: Forty Sprague-Dawley rats were divided into four groups of five males and five females per group: an intravenous (IV) injection of 1.0 mL of normal saline solution per animal was administered to group 1 (G1, control group); an IV injections of 0.1, 0.5, and 1.0 mL of Guseonwangdo-go glucose pharmacopuncture per animal were administered to experimental groups 2, 3, and 4 (G2, G3, and G4), respectively. General symptoms, body weights, hematological and biochemical test results, and necropsy histopathological observation were recorded in all groups. In the statistical analyses, significance was determined by using the one-way analysis of variance (ANOVA). The significance level was 0.05 in all comparisons. Results: For 14 days, no deaths or abnormalities were observed in any of the 4 groups. The body weights of all groups continuously increased during the observation period. In the hematological test, the WBC count was significantly increased in female rats of G4 compared to the control group, but this difference was considered not to be statistically meaningful. No significant biochemical changes were observed. On necropsy, crust formation was observed in one rat of the control group, and granulation tissues were observed around the injection site in one rat of G4; these changes were concluded to have been caused by injection of the needle into a vein. Conclusion: The findings suggest that the lethal dose of Guseonwangdo-go glucose pharmacopuncture is more than 1.0 mL per animal in both male and female rats. Thus, we can conclude that Guseonwangdo-go glucose pharmacopuncture injection is relatively safe to use in acute toxicity tests. Further studies are needed to establish more detailed evidences of its toxicity.

  • Objectives: This study was performed to analyze the toxicity of the test substance, anti-inflammatory pharmacopuncture (AIP), when used as a single intramuscular-dose in 6-week-old, male and female Sprague-Dawley rats and to find the lethal dose. Methods: The experiment was conducted at Biotoxtech according to Good Laboratory Practices. Twenty (20) female and 20 male Spague-Dawley rats were divided into 4 groups of five 5 female and 5 male animals per group. The rats in the three experimental groups received single intramuscular injections with 0.1-$m{\ell}$, 0.5-$m{\ell}$ and 1.0-$m{\ell}$/animal doses of AIP, Groups 2, 3, and 4, respectively, and the control group, Group 1, received a single intramuscular injection with a 1.0-$m{\ell}$ dose of normal saline. Clinical signs were observed and body weight measurements were carried out for 14 days following the injections. At the end of the observation period, hematology, clinical chemistry, histopathological tests and necropsy were performed on the injected parts. Results: No deaths occurred in any of the groups. Also, histopathological tests showed that AIP had no effect on the injected parts in terms of clinical signs, body weight, hematology, clinical chemistry, and necropsy. Conclusions: As a result of single intramuscular-dose tests of the test substance AIP in 4 groups of rats, the lethal dose for both males and females exceeded $1.0m{\ell}$/animal. Therefore, AIP is a relatively safe pharmacopuncture that can be used for treatment, but further studies should be performed.
