Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- Young adult male and female rats of the CD strain (remote Sprague-Dawley origin), supplied by Charles River (UK) Ltd., were
about 5-6 weeks old at arrival and were within the body weight range of 120-137 g. This strain has been widely used in toxicological testing since its establishment under SPF conditions in 1955.
The animals were housed in high density polypropylene GPR-1 cages measuring 56x38x18 cm, with stainless steel grid floors and tops
(North Kent Plastics Ltd., Dartford, Kent, England). The grid floor ensured rapid removal of waste material to undertrays, which
were cleaned out as necessary. A minimum floor area of 400 sq. cm per rat was provided by grouping no more than five animals of
the same sex in each cage. Mobile racks held up to eighteen suspended cages each.
All rooms in the limited access area were kept at slight positive pressure relative to the outside and each had its own filtered air
supply giving about 15 complete air changes per hour without recirculation. Maximum and minimum temperatures during the
preceding 24-hour period and relative humidity were recorded at the beginning of each working day. Target ranges for temperature and
relative humidity were 21° ± 2°C and 55 ± 15% RH. Electric time-switches regulated a lighting cycle of twelve hours artificial
light per day.
A commercially-available powdered rodent pelletted diet (Altromin 1321N) was fed without restriction except on the night before
dosing.
Animals had free access to tap water supplied in two bottles per cage. The water was taken from the public supply after passing
through a water purifier (Tami-Tana, Israël, Ltd.) and meets the accceptable WHO Standard for quality of water.
On arrival each rat was inspected and only suitable animals were accepted for use. A sample of the delivery was weighed, and the
range of body weights recorded for each sex.
An acclimatisation period of seven days was allowed between arrival at the laboratory and administration of the test material.
A daily check on the general condition of the animals was recorded and this record was consulted before animals were put on study.
Ear-marks uniquely identifying each animal within the room were made before the start of this study. At the same time the sex of
each animal was confirmed.
Each cage was relabelled with details of the schedule number, unique cage reference, treatment level and route of
administration, ear-mark, numbers and sex of occupants, responsible personnel and date of dosing.
Food was removed from the hoppers at about 16:00 hours on the day before dosing. This ensured that the stomach was void of food at
the time of dosing.
Body weight the day before dosing was within the range 159-l83 g for male rats and 141-150 g for females. At the time of dosing
male rats were within the body weight range of l47"l67 g and females 125-133 S- The animals were about 7-8 weeks old at this
time.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- maize oil
- Details on oral exposure:
- The test material was prepared in maize oil at a constant volume-dosage of 20 ml/kg. The test material was homogenized and
then sonicated to achieve an homogeneous solution. Dosages were expressed gravimetrically (mg/kg) and were freshly prepared on the
morning of administration.
A single group of five male and five female rats was dosed at a dose level of 2500 mg/kg. This dose level was selected on the
basis of a range finding study, as it is the maximum practical dose that can be handled.
Dose volume was determined for each rat according to fasted body weight on the morning of dosing. The dose volume was divided into
two applications with approximately 1 hour between the applications . The dosing was performed with a feeding catheter introduced into the
oesophagus allowing instillation of the test material into the lumen of the stomach.
Food hoppers were returned to the cage immediately after dosing was completed. - Doses:
- A single group of five male and five female rats was dosed at a dose level of 2500 mg/kg. This dose level was selected on the
basis of a range finding study, as it is the maximum practical dose that can be handled. - No. of animals per sex per dose:
- A single group of five male and five female rats was dosed at a dose level of 2500 mg/kg
- Control animals:
- no
- Details on study design:
- Animals were returned to their cages immediately after dosing.
Animals were inspected three times on the day of dosing and twice daily thereafter (once daily at weekends and holidays). The type, time of onset and duration of reactions to treatment were recorded.
Body weights were recorded on the day before dosing, on Day 1, and weekly thereafter. The test was terminated on Day 15.
Animals were killed at termination of the study by C02 inhalation and were examined at necropsy by the following procedure to detect
pathological changes caused by sublethal dosages of the test material. All body cavities were opened. Larger organs were
narrowly sectioned and the gastro-intestinal tract was opened at intervals for examination of the mucosal surfaces. All
abnormalities were described or normal appearance of major organs confirmed for each animal.
Results and discussion
- Preliminary study:
- A preliminary study was performed in the same way as the main study using 5 groups each of 2 male and 2 female rats treated with the test material at 50, 500, 1000, 1800 and 2500 mg/kg diluted in maize oil and applied at a volume of 10 mL/kg.
No death was noted during the course of the preliminary study.
