Administration / exposure

Route of administration:

oral: gavage

Vehicle:

other: maize oil

Details on oral exposure:

MAXIMUM DOSE VOLUME APPLIED: 10ml/kg in maize oil

Doses:

2 g/kg

No. of animals per sex per dose:

10M, 10F

Control animals:

no

Details on study design:

- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The body weight of each animal was recorded on the day prior to dosing, the day of dosing, day 8 and 15. On day 15, rats were sacrificed and subjected to a gross necropsy consisting of a detailed external and internal examination.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight,organ weights, histopathology, other: . All animals were autopsied at the end  of the study, larger organs were sectioned and the  gastro-intestinal  tract opened at intervals for examination of the mucosal surface. There  was no histopathological examination

Results and discussion

Effect levels

Sex:

male/female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Mortality:

There were no deaths.

Clinical signs:

other: Hunched posture and piloerection were observed in male animals between 30 minutes and 3 hours after dosing. The animals were fully recovered by day 2. There were no systemic signs of reaction to treatment amongst the females.

Gross pathology:

Necropsy revealed no significant macroscopic lesions.

Other findings:

POTENTIAL TARGET ORGANS: None indicated.
SEX-SPECIFIC DIFFERENCES: Males may be rather more susceptible as they  exhibited some signs of intoxication while females did not. However the  females may have been slightly older than the males given that the weight  range was similar in both sexes. There were no mortalities in either sex.

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The rat oral LD50 for Linevol 79 is >2 g/kg. Signs of intoxicaton consisted of hunched appearance and piloerection on dosing day. There were no significant macrosopic lesions.
