Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- Five male and 5 female rats of the Sprague-Dawley strain (obtained from Harlan Industries, Inc., Indianapolis, Indiana), weighing from 200 to 208 grams, were used for this study. The rats were housed by sex, in groups of 5 rats per cage, in hanging wire-mesh cages in temperature and humidity controlled quarters. They were maintained in accordance with the recommendations contained in H.E.W. Publication No. 74-23 (N.I.H.) entitled "Guide for the Care and Use of Laboratory Animals". The rats were conditioned for a minimum of 5 days prior to study initiation. Water and Purina Laboratory Chow were available ad libitum, except for an overnight period of approximately 18 hours Immediately preceding oral administration during which food, but not water, was withheld.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- corn oil
- Details on oral exposure:
- The test material was administered orally by gavage as a suspension in corn oil at the following dosage level to male and female rats: 10,000 mg/kg.
The dosage level was administered at a volume of 40 ml/kg. - Doses:
- 10,000 mg/kg
- No. of animals per sex per dose:
- 5 male
5 female - Control animals:
- not specified
- Details on study design:
- Observations for pharmacotoxic signs were recorded during the first 4 hours following dosing, at 24 hours and daily thereafter for a total of 14 days. The rats were observed for mortality during the first four hours following dosing and twice daily thereafter for a total of 14 days. Body weights were recorded immediately prior to dosing (control weight) and at 7 and 14 days. All rats which died on study were subjected to gross necropsy examination as were all survivors at the end of the 14 day observation period
