Objectives Bangpungtongsung-san(Fangfengtongsheng-san) has been traditionally prescribed a a restorative medicine. Methods In this study, we investigated the acute toxicity of water-extracted Bangpungtongsung-san(Fangfengtongsheng-san). 20 male and 20 female mice were orally treated of Bangpungtongsung-san(Fangfengtongsheng-san) at the respective doses of 0 (control group), 1250, 2500 and 5000mg/kg for 14days. Results We observed survival rates, general toxicity, change of body weight and examined microscopic changes of some organs. Conclusions Compared with the control group, we could no find any toxic alteration in all treated groups (1250, 2500 and 500mg/kg). $LD_{50}$ of Bangpungtongsung-san(Fangfengtongsheng-san) might be over 5000mg/kg and it was very safe to ICR mice.

Objectives In this study, we investigated the acute toxicity and safety about fermented Bangpungtongsung-san(Fangfengtongsheng-san) extract. Methods To evaluate the acute toxity and safety, fermented Bangpungtongsung-san (Fangfengtongsheng-san) at the respective doses of 0(control group), 1250, 2500 and 5000 mg/kg were orally treated to 20 male and 20 female mice. After single administration, we observed survival rates, general toxicity, changes of body weight and autopsy. Results Compared with the control group, we could not find any toxic alteration in all treated groups (1250, 2500 and 5000 mg/kg). Conclusions $LD_{50}$ of fermented Bangpungtongsung-san(Fangfengtongsheng-san) extract might be over 5000 mg/kg and it is very safe to ICR mice.

Objectives : This study was conducted to evaluate the acute toxicity and safety of Bangpungtongsung-san (Fangfengtongsheng-san) in Sprague-Dawley rat though the current regulatory guideline. Methods : The preliminary study showed that the single oral administration of Bangpungtongsung-san (Fangfengtongsheng-san) did not induce any toxic effect at a dose level of 2000 mg/kg. Based on the results, 2000 mg/kg was selected as the limited dose. In this study, 10 rats of each sex were randomly assigned to two groups of 5 rats each and were administrated singly by gavage at dose levels of 0 and 2000 mg/kg. Mortalities, clinical signs, and body weight changes were monitored for the 15-day period following administration. At the end of observation period, all animals were sacrificed and complete gross postmortem examinations were performed. Results : Throughout the study period, no treatment-related deaths were observed. There were no adverse effects on clinical signs, body weight, and gross findings at all treatment groups. Conclusions : These results showed that the single oral adminstration of Bangpungtongsung-san (Fangfengtongsheng-san) did not cause any toxic effect at the dose levels of 2000 mg/kg in rats. In conclusion, the $LD_{50}$ of Bangpungtongsung-san (Fangfengtongsheng-san) was considered to be over 2000 mg/kg body for both sexes.

Three herbal formulas (Bangpungtongsung-san, Ohyaksungi-san, and Ojeok-san) for wind-cold and heat pain symptom were applied to investigate the immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses in murine macrophage cell line (RAW 264.7) and ovalbumin (OVA)-immunized mice. This study was carried out in nitric oxide (NO) synthesis in RAW 264.7 cells and cellular proliferation in mouse splenocytes according to three herbal formulas. C57BL/6 mice were immunized intraperitonially with OVA/aluminium ($100\;{\mu}g/200\;{\mu}g$/mouse) on day 1, 8, and 15. Three herbal formulas were administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, lgG1, and total IgM classes) in plasma were measured. Ohyaksungi-san increased NO synthesis in RAW 264.7 cells. Ojeok-san and Ohyaksungi-san significantly enhanced cellular proliferation by LPS and Con A in splenocytes from OVA-immunized mice (p<0.001). Three herbal formulas for wind-cold and heat pain symptom also significantly enhanced plasma OVA-specific IgG, IgG1, and total IgM levels compared with the OVA/Alum group. These results suggested that three herbal formulas for wind-cold and heat pain symptom could be used as stimulator of immune response.
