Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Remarks:
- distilled
- Details on oral exposure:
- Animals have been fasted prior to substance administration by withholding food overnight. They receive by gavage, according to the bodyweight, the product diluted in distilled water (Meram batch 62417), previously heated at 80°C, at the single dose of 2000mg/kg under a constant volume of 10 mL/kg. The preparation is kept up under magnetic stirring till obtaining a homogeneous mixture, to ambient temperature.
- Doses:
- 2000mg /kg body weight
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- Observations:
The animals are observed daily for 14 days after the treatment
- Clinical examinations
A clinical observation is carried out at least once a day in order to evaluate the general appearence, the behaviour and vegetative functions of the animals. An individual clinical observation is realized one hour after treatment. The continous observations during the five following hours are renewed each following day.
Body weight are taken just prior the test material administration (D1) and again on days 4, 8 and 15.
- Macroscopic examinations
At terminaison of the 14 days observation days, the rats are sacrified after barbituric anaesthesia, then autopsied. All abnormalities are recoded.
No tissue is saved.

Study Objective
To estimate the potential for toxicity and lethality of a single dose level of a test substance in the rat.
Regulatory compliance
This tudy was conduced according to OECD 401 guideline in compliance with Good Laboratory Practices.
Experimental procedure
The test item was administred to 10 albnino rat, Sprague Dawley OFA (5 males and 5 females) at the dose of 2000mg/kg body weight.
Animals have been fasted prior to substance administration by withholding food overnight. They receive by gavage, according to the bodyweight, the product diluted in distilled water (Meram batch 62417), previously heated at 80°C, at the single dose of 2000mg/kg under a constant volume of 10 mL/kg. The preparation is kept up under magnetic stirring till obtaining a homogeneous mixture, to ambient temperature.
Observation
The test item does not cause any death.
The test item has no significant toxic effect on the animals' behaviour or vegetative functions.
the test item does not modify their weight growth.
The test item does not cause any gross lesion visible at autopsy.
Conclusion
Under the experimental conditions adopted, oral LD0 of the test preparation is higher than 2000 mg/kg in the rat.
According to 67/548/EEC directive, the test preparation is unclassified if swallowed.
