  • Objective : The purpose of this study was to investigate acute and subacute toxicity and sarcoma-180 anti-cancer effects of herbal acupuncture with cultivated wild ginseng (distilled) in mice and rats. Method : Balb/c mice were injected intravenous with cultivated wild ginseng herbal acupuncture for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were injected intravenous with cultivated wild ginseng herbal acupuncture for subacute toxicity test. The cultivated wild ginseng herbal-acupuncture was injected at the tail vein of mice. Results : 1. In acute $LD_{50}$ toxicity test, there was no mortality thus unable to attain the value. 2. Examining the toxic response in the acute toxicity test, there was no sign of toxication. 3. In acute toxic test, running biochemical serum test couldn't yield any differences between the control and experiment groups. 4. In subacute toxicity test, there was no sign of toxication in the experimental groups and didn't show any changes in weight compared to the normal group. 5. In subacute toxicity test, biochemical serum test showed significant increase of Total albumin, Albumin, and Glucose in the experimental group I compared with the control group. Significant decrease of GOT, ALP, GPT, and Triglyceride were shown. In experiment group II, only Glucose showed significant increase compared with the control group. 6. Measuring survival rate for anti-cancer effects of Sarcoma-180 cancer cell line, all the experimental groups showed significant increase in survival rate. 7. Measuring NK cell activity rate, no significant difference was shown throughout the groups. 8. Measuring Interleukin-2 productivity rate, all the experimental groups didn't show significant difference. 9. For manifestation of cytokine mRNA, significant decrease of interleukin-10 was witnessed in the experimental group compared to the control group. Conclusion : According to the results, we can conclude cultivated wild ginseng herbal acupuncture caused negligible toxicity, and had anti-tumor effects in mice.

  • 1. Objectives: The aim of this study is data analysis for acute toxicity and safety of Cheongsimyeonja-tang. 2. Methods: We investigated the acute toxicity for water-extracted Cheongsimyeonja-tang. Fifty five male and female mice were observed for 14 days after one day oral administration of Cheongsimyeonja-tang at the respective doses of 0 (control group), 2560, 3200, 4000 and 5000 mg/kg. 3. Results: We observed survival rates, general toxicity, change of body weight and autopsy. In animals administered with Cheongsimyeonja-tang, there were nither dead animals nor significant changes of body weights. In addition, no differences were found between control and treated groups in clinical sign and autopsy. 4. Conclusion: The data confirmed that Cheongsimyeonja-tang is free from the toxicity and safety problems in treated groups. Compared with the control group, we could not find any toxic alteration in all treated groups(2560, 3200, 4000 and 5000 mg/kg). Lethal Dose 50 (LD50) value for mice was more than 5000 mg/kg per oral for both male and females. It suggest that Cheongsimyeonja-tang in mice is considered to be safe.

  • It has been demonstrated that the injection of naked DNA expressing vascular endothelial growth factor 165(VEGFl165) to the affected area can provide significant therapeutic effects on peripherol artery occlusive diseases. Success with this type of gene therapy highly depends on the quality of the vector delivering the therapeutic gene, especially in terms of the level and duration of gene expression in the localized area. We have recently developed a vector expressing VEGF165(pCK-VEGF) for the treatment of peripheral artery occulsive diseases and demonstrated high level expression of VEGF165 in mouse skeletal muscle. This study was designed to assess the acute toxicity of intramuscularly injected pCK-VEGF in BALB/c mice and Sprague-Dawely rats. There was no evidence of any changes in clinical signs, body weights, or gross pathological signs. We estimate LD50 values of pCK-VEGF higher than 50mg/kg in mice and 20 mg/kg in rats by intramuscular injection.

  • Acute (24 h) and chronic (90 days) oral toxicity studies on the ethanol extract of Trigonella foenumgraecum Leguminosae (L.) seeds were carried out. Acute dosages were 0.5, 1.0 and 3 g/kg while chronic dosage was 100 mg/kg per day of the extract. All morphological, biochemical, haematological and spermatogenic changes, in addition to mortality, body weight changes and any change in vital organs were recorded. Histopathological investigations were done on vital organs. Growth arrest in the treated animals was observed. The treated mice gained no significant weight during chronic treatment while there was a significant gain in body weight of the control group mice. Biochemical studies revealed a significant decrease in blood sugar levels of fenugreek treatment groups while haematological parameters remained comparable to the control. In the treatment, male group there was a significant decrease in weight of testes as compared to the control. There was a marginal weight gain in kidney weight of mice after chronic treatment as compared to the control. Fenugreek chronic treatment caused a highly significant spermatotoxic effects in male mice.

  • The study was carried out to evaluate the acute toxicity of enrofloxacin-colistin combination via a single oral(p.o.)and intravenous(i.v.) administration in ICR mice. All procedures of the test were performed by the established regulation of Korean National Institute of Safety Research (1994. 4.14). The maximal dose of oral and intravenous routes was 5,000mg/kg and 90mg/kg, consisting with each 6 groups including control of male and female, respectively. As the results, $LD_{50}$m}'s of the combinations showed 3,075mg/kg (f)and 2,564mg/kg(m) after oral administrations, together with 48mg/kg(f) and 40mg/kg(m) after intravenous administration. These facts indicated that acute toxicitiy of enrofloxacin-colistin combination were different depending on the administration routes and sexes in ICR mice. In conclusion, the route of enrofloxacin-colistin combination must not choose as i.v. route administration in terms of acute toxicity based on $LD_{50}$.
