- not specified
Results and discussion
- Preliminary study:
- Two rats of each sex were employed in preliminary range finding studies at the maximum required dosage of 5000 mg/kg.No signs of reaction to treatment were observed during a preliminary study. Bright orange coloured faeces were present on Days 2 and 4. Necropsy on Day 15 revealed no abnormalities,except for orange-colouration of the kidneys.

- Mortality:
- No mortality was observed at 5000 mg/kg bw.
- Clinical signs:
- other: The overt signs of reaction to treatment comprised piloerection at 1-2.5 hours after treatment and a decrease in motor activity over the period 0.5 - 6 hours, in all animals. The presence of bright-red pigmented faeces from the day of dosing to Day 3 prob
- Gross pathology:
- Terminal necropsy on Day 15 revealed no significant lesions that could be attributable to treatment; however, the renal cortices were stained slight orange, showing some deposition of material.
- Other findings:
- Under the conditions of this study, test chemical was absorbed sufficiently to produce, in all animals, minor signs of reaction to treatment. Staining of the renal cortices afforded evidence of urinary excretion.

Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute oral toxicity dose (LD50) was considered to be >5000 mg/kg bw, when groups of 5 male and 5 female Wistar rats were treated with the given test chemical via oral gavage route.
- Executive summary:
The acute oral toxicity study was conducted in wistar rats by using test chemical at the dose concentration of 5000 mg/kg bw. The given test chemical (Procion Orange H-ER, ORG/98, Code B6100 Z0593, a powder) was prepared for administration as a 50% w/v aqueous solution but dosages were expressed gravimetrjcally. Dosages were determined according to the fasted body weight of the animals, which were dosed orally at approximately 11.00 hours with a dosage volume of 10 ml/kg. In preliminary range finding studies, 2 rats of each sex were employed at the maximum required dosage of 5000 mg/kg. No signs of reaction to treatment were observed during a preliminary study. Bright orange coloured faeces were present on Days 2 and 4. Necropsy on Day 15 revealed no abnormalities, except for orange-colouration of the kidneys. In main study, the animals were closely observed throughout the first hour for signs of reaction to the administered material, followed by examination at regular intervals for the remainder of the day. Subsequently, until termination, they were examined at least daily. The time-course of reaction to treatment and subsequent recovery was assessed subjectively by visual appraisal of the animals and, more objectively, by examination of the bodyweight changes 7 and 14 days after dosing. All animals that died were subjected to thorough necropsy with the objective of locating target tissues damaged by the test material. Animals which survived to Day 15 were killed and similarly examined to assess any residual or delayed pathology. Signs of reaction and mortalities were recorded during a 14-day observation period. No mortality was observed at 5000 mg/kg bw. The overt signs of reaction to treatment comprised piloerection at 1-2.5 hours after treatment and a decrease in motor activity over the period 0.5 - 6 hours, in all animals. The presence of bright-red pigmented faeces from the day of dosing to Day 3 probably indicated poor absorption of the dose. Animals gained weight normally over the period of observation. Terminal necropsy on Day 15 revealed no significant lesions that could be attributable to treatment; however, the renal cortices were stained slight orange, showing some deposition of material. Under the conditions of this study, test chemical was absorbed sufficiently to produce, in all animals, minor signs of reaction to treatment. Staining of the renal cortices afforded evidence of urinary excretion. Hence, the LD50 value considered to be >5000 mg/kg bw, when groups of 5 male and 5 female Wistar rats were treated with the given test chemical via oral gavage route.
