This study was carried out to investigate the acute toxicity of surfactin C in mice. Surfactin C was administered orally at does of 0, 381, 610, 977, 1562 and 2500 ㎎/㎏. Number of deaths, clinical signs, body weights, feed and water consumptions, and biochemical examinations were investigated for 14 days after single oral administration of surfactin C. LD?? value was over 2500 ㎎/㎏ in mice. In addition, no differences were found between control and treated groups in clinical signs, body weight gains, hematology, serum chemistry, feed and water consumptions. The results indicate that surfactin C did not show any toxic effects at 2500 ㎎/㎏ in mice.

This study was performed to evaluation the skin and eye irritation of etofenprox 8% and spinosad 4% combination in male New Zealand White rabbits. In skin irritation test, the combination of etofenprox and spinosad did not showed any change of body weight but caused slight skin irritation with the P.I.I. (primary irritation index) value 0.25. The etofenprox and spinosad combination showed severe eye irritation 1 h, 24 h, 48 h, and 72 h after ocular treatment, having the A.O.I. (acute ocular irritation) value of 37.3. Therefore, these result indicated that the combination of etofenprox and spinosad might be irritant formulation on eye and skin.

The present study was carried out to investigate the potential acute toxicity of safflower seed by a single oral dose in ICR mice. Twenty animals of each sex were randomly assigned to four groups of 5 rats each and were administered singly by gavage at dose levels of 0, and 2,500 mg/kg bodyweight. Mortalities, clinical findings, and body weight changes were found and complete gross postmortem examinations were performed. Throughout the study period, no treatment-related deaths were observed. There were no adverse effects in clinical signs, body weight, and gross findings at any dose tested. The results showed that the single oral administration of safflower seed did not cause any toxic effect at the dose levels of 2,500 mg/kg in rats and the minimal lethal dose was considered to be over 2,500 mg/kg body weight for both sexes.
