MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg bw
CLASS METHOD
- Rationale for the selection of the starting dose: Starting dose was selected on the basis of the available information about the test item. The acute toxic class method was carried out involving a stepwise procedure with the use of 2000 mg/kg bw as the starting dose in three female rats. No animal died in the first step at 2000 mg/kg bw dose level. Therefore, treatment with 2000 mg/kg bw was repeated on further three female rats. Again, no animal died in the second step, thus, no further testing was required. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 6
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Inspection for signs of morbidity and mortality were made twice daily at the beginning and end of the working day. The body weight were recorded on day 0 (shortly before the treatment), on day 7 and on day 15 on all animals with a precision of 1 g, respectively.
- Necropsy of survivors performed: Yes. All animals were subjected to gross pathology. All animals were exsanguinated under isoflurane anaesthesia. After examination of the external appearance the cranial, thoracic and abdominal cavities were opened and the appearance of the tissues and organs were observed. All gross pathological changes were recorded for each animal on the post mortem record sheets.
- Other examinations performed: Clinical Observations: Animals were observed individually after dosing once during the first 30 minutes, then 1 h, 2 h, 3 h, 4 h, after the treatment and once per day for 14 days thereafter. Individual observations were performed on the skin and fur, eyes and mucous membranes and also respiratory, circulatory, autonomic and central nervous system, somatomotor activity and behaviour pattern. Particular attention was directed to observation of tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma. - Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- The test item did not induce mortality following a single oral administration to female rats at a dose of 2000 mg/kg bw. All female rats survived the performed treatment until the end of the 14-day observation period.
- Clinical signs:
- other: No treatment related symptoms were observed throughout the treatment day and 14-day post-treatment period at any groups of the female animals.
- Gross pathology:
- All animals treated with 2000 mg/kg bw dose of test item survived until the scheduled necropsy on Day 15. Slight hydrometra was detected in animal No.: 230 of group 1 and moderate hydrometra was observed in two females (No.: 234 of the group 1 and No.: 255 of the group 2). Hydrometra is a physiological finding and connected to the cycle of the animal. No pathological changes were found related to the effect of the test item during the macroscopic examination of animals.
- Interpretation of results:
- other: not classified
- Conclusions:
- The test item did not induce mortality following a single oral administration to female rats at a dose of 2000 mg/kg bw. There were no toxic clinical signs and any related to the effect of the test item found in body weights and body weight gains during the study. Autopsy revealed no treatment related pathological changes.
- Executive summary:
An acute oral toxicity study was carried out using the class method according to OECD guideline 423. The method was conducted using a stepwise procedure with the use of 2000 mg/kg bw as the starting dose in three female rats. The starting dose was selected on the basis of the available information about the test item. The acute toxic class method was carried out involving a stepwise procedure with the use of 2000 mg/kg bw as the starting dose in three female rats. No animal died in the first step at 2000 mg/kg bw dose level. Therefore, treatment with 2000 mg/kg bw was repeated on further three female rats. Again, no animal died in the second step, thus, no further testing was required. The stopping criteria of Annex 2d of OECD Guideline No. 423 were met. Animals were weighed, observed for lethality and toxic symptoms for 14 days after the treatment. Gross pathological examination was carried out on 15th day after the treatment.
Lethality, Clinical symptoms and Body weight:
No lethality was noted following oral administration of a single dose of 2000 mg/kg bw. In first and second step, no clinical symptoms were observed on the day of the treatment and during the 14-day observation period, the general state and behaviour of experimental animals were normal. The body weight development was normal in all animals.
Gross pathology:
Altogether 6 animals were subjected to scheduled sacrifice during the study. All organs of the animals treated with 2000 mg/kg bw dose proved to be free of treatment related gross pathological changes.
Evaluation:
The method used is not intended to allow for the calculation of a precise LD50 value. However for this acute oral toxicity study with the test item in rats the determined LD50 is greater than 2000 mg/kg bw (LD50 ≥ 2000 mg/kg bw). The test item is ranked into classes of Globally Harmonized Classification System (GHS) described in the OECD Guideline No. 423 as not classified.
