Test animals

Species:
rat
Strain:
Wistar
Sex:
female
Details on test animals or test system and environmental conditions:
TEST ANIMALS
- Females nulliparous and non-pregnant: yes
- Age at study initiation: 8 weeks
- Weight at study initiation: 196-206g

- Housing: 3 animals / cage
- Diet (e.g. ad libitum): ad libitum
- Water (e.g. ad libitum): ad libitum
- Acclimation period: 5-6 days

ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19.4 – 24.8°C
- Humidity (%): 30 - 68%
- Air changes (per hr): 15 – 20 air exchanges/hour
- Photoperiod (hrs light): 12 hours daily, from 6.00 a.m. to 6.00 p.m.

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
methylcellulose
Details on oral exposure:
- Concentration in vehicle: 200 mg/mL
- Amount of vehicle (if gavage): 10 mL/kg bw

CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: The initial dose level was selected by the Study Director to be that which is most likely to produce mortality in some of the dosed animals. In the lack of any preliminary toxicological information, 2000 mg/kg bw was selected to be the starting dose.
Doses:
2000 mg/kg bw of B331
No. of animals per sex per dose:
6 females (2 groups of 3 animals)
Control animals:
no
Details on study design:
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Clinical observations were performed on all animals at 30 minutes, 1, 2, 3, 4 and 6 hours after dosing and daily for 14 days thereafter
- Necropsy of survivors performed: yes
- Other examinations performed: Individual observations were performed on the skin, fur, eyes, mucous membranes, 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.
The body weight was recorded on the day before treatment (Day -1), on the day of the treatment (Day 0) and weekly thereafter.

Results and discussion

Effect levels
Key result
Sex:
female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Based on:
test mat.
Mortality:
B331 did not cause mortality at a dose level of 2000 mg/kg bw.
Clinical signs:
other: Treatment with B331 caused hunched back in all the experimental animals at the dose level of 2000 mg/kg bw. All animals were symptom free from 3 hours after treatment (Day 0). However coloured faeces (blackish) were observed for all the experimental anima
Gross pathology:
There was no evidence of the macroscopic observations at a dose level of 2000 mg/kg bw.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Under the conditions of this study, the acute oral LD50 value of the test item B331 was found to be above 2000 mg/kg bw in female CRL:WI rats.
