  • Objectives: This study was conducted to evaluate the safety of SU-Eohyeol pharmacopuncture (SUEP) by assessing its potential to cause chromosomal abnormalities in Chinese hamster lung cells (CHL/IC). Methods: A dose-curve was conducted to determine the highest dose of SUEP. Doses of 10, 5, 2.5, 1.25, 0.625, and 0.313% were used, and no cytotoxicity or SUEP precipitation was observed. SUEP doses of 10, 5, and 2.5%, with positive and negative controls, were used in a chromosome aberration test. Results: In this study, the frequency of abnormal chromosomal cells in the SUEP group did not show a statistically significant difference from that of the negative control group in short-term treatments with and without metabolic activation and the continuous treatment without metabolic activation. Compared with the negative control group, the positive control group had a significantly higher frequency of cells with structural chromosomal abnormalities. This test's results satisfied all conditions for determining the results. Conclusion: SUEP did not induce chromosomal aberrations under the conditions of this study. Other toxicity evaluations, safety studies in humans, and various clinical trials are required to evaluate the safety and efficacy of SUEP.

  • SU-Eohyeol pharmacopuncture(SUEP) was developed by adding Cervi Pantotrichum Cornu to Jungsongouhyul pharmacopuncture. This genotoxicity evaluation was performed to evaluate the mutagenic potential of the test substance SUEP agent using histidine, which requires strains of Salmonella typhimurium (TA98, TA100, TA1535, TA1537), and tryptophan, which requires Escherichia coli (WP2uvrA) strain in the presence and absence of metabolic activation. According to the results of the dose range finding study conducted prior to the main study, the dose levels of the test substance in the main study were determined as 100, 50, 25, 12.5, 6.25%, and positive and negative controls were established. As a result of the main study, the mean number of revertant colonies compared to negative controls was less than 2-fold at all dose levels of SUEP in all strains with and without metabolic activation. In the positive control group, the mean number of revertant colonies for each strain was markedly increased by more than two times compared to the negative control group. Based on the result of this study, the test substance, SUEP did not show any indication of mutagenic potential under the conditions of this study.

  • Objectives: This toxicological study was performed to assess for potential toxicity and to determine the approximate lethal dose of SU-Eohyeol pharmacopuncture (SUEP) following a single intramuscular injection of SUEP into male and female Sprague-Dawley (SD) rats. Methods: The groups in our experiment consisted of an experimental group treated with SUEP at a dose of 1.0 mL/animal and a control group injected with a normal saline solution, and five male and female rats were placed in each group. Each animal was administered a single intramuscular injection. We monitored all rats for clinical signs and body weight changes for 14 days after administration. At the end of the observation period, the rats were euthanized and autopsied, and localized tolerance examinations were conducted at the site of administration of the test substance. Results: There were no deaths in either sex in the SUEP-treated group. There was no significant difference between the SUEP-treated group and the control group in the clinical signs and weight changes among the rats. In addition, no significant SUEP-related changes were observed on autopsy findings or local tolerance examinations at the injection site by histopathological examination. Conclusion: Our results suggest that the approximate lethal dose of a single intramuscular administration of SUEP in female and male rats under the conditions of this study is greater than 1.0 mL/animal. To determine the safety of the use of SUEP in Korean medical clinical practice, additional toxicity studies will be needed.

  • Objectives : The purpose of this study was to evaluate the potential of the test substance, SU-Eohyeol Pharmacopuncture (SUEP), to induce micronuclei in bone marrow cells of Sprague-Dawley (SD) Rats. Methods : The dose range preliminary study was performed first. 1 ml/animal was selected as the high dose of this study. Two additional lower dose levels (0.5 and 0.25 ml/animal) were produced by applying a geometric ratio of 2. In addition, the positive and negative control groups were set. Then, after intramuscular administration (1 ml/animal) of SUEP to 8-week-old male SD rats, an in vivo micronucleus test was performed to evaluate the induction of micronuclei in SD rat bone marrow cells. Results : As a result of the main study, the incidence of micronucleated polychromatic erythrocytes (MNPCE) in polychromatic erythrocytes (PCE) in the test substance SUEP groups was not statistically significantly different from the negative control group. In addition, the ratio of PCE to total erythrocytes in the test substance SUEP groups was not statistically significantly different from the negative control group. In the positive control group, the incidence of MNPCE in PCE was statistically significantly increased when compared to the negative control group. The ratio of PCE to total erythrocytes in the positive control group was not statistically significantly different from the negative control group. Conclusions : Based on these results, the test substance, SUEP, did not have any potential to induce micronuclei formation in bone marrow cells of rats under the conditions of this study.

  • We report a case of generalized dystonia that developed from oromandibular dystonia and improved following Korean medicine treatment. The patient was hospitalized for 18 days and treated with herbal medicine, mainly Hyeongbangsabaek-san and Soyangbowi-tang, acupuncture, electroacupuncture, pharmacopuncture, cupping, and moxibustion. To evaluate the clinical effects of the treatment, we used the Unified Dystonia Rating Scale (UDRS) and Global Dystonia Severity Rating Scale (GDS) and checked dyskinesia occurrence in a diary recorded by the patient's guardian. After 18 days of hospitalization, the UDRS for the trunk, upper extremities, and lower face improved by more than 50%, and the GDS for the whole region, except the larynx and lower face, also improved. In addition, the maximum duration of dystonia decreased from 6 hours to 3 hours, and the pain and numbness associated with dystonia disappeared. This case suggests that Korean medicine treatment is effective in treating generalized dystonia.
