Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
Environmental conditions: The animals were kept in air conditioned rooms with 10-15 air circulation cycle per hour, temperature between 22-250C, relative humidity 40-60% and illumination cycle set to 12 hours artificial fluorescent light and 12 hours dark.
Accommodation: Groups of five animals of similar sex in polypropylene cages with stainless steel grill top, facilities for food and water bottle and bedding of clean paddy husk.
Diet: Pelleted feed supplied by Pranav agro Industries Ltd., B7/6 Ramesh Nagar, Delhi, India
Water: Community tap water passed through ‘Aqua Guard on line water filter’, was kept in glass bottles, ad-libitum
Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- water
- Details on exposure:
- The three dose levels of test compound (62.5, 250 & 1000 mg/kg b.wt) were used to confirm the sub acute dermal toxicity. The 1000 mg/kg b.wt is the highest dose for sub acute toxicity study
- Duration of treatment / exposure:
- 28 days
- Frequency of treatment:
- The test substance was applied uniformly daily over an area approximately 10 per cent of the total body surface area in graduated doses for a period of 28 days. Between applications the test substance is held in contact with the skin with a porous gauze dressing and non-irritating tape. The test site was covered in a suitable manner to retain the gauze dressing and test substance and ensure that the animals cannot ingest the test substance.
- No. of animals per sex per dose:
- 5 male and 5 female in test and control group
- Control animals:
- yes
- Details on study design:
- Age of test organisms: 8 to 10 weeks
