Test animals
- Species:
- rat
- Strain:
- other: Wistar Crl:WI (Han)
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River Deutschland, Sulzfeld, Germany
- Age at study initiation: approximately 10 weeks
- Weight at study initiation: 269-284 g (males), 181-194 g (females)
- Housing: animals were housed individually in labelled Makrolon cages (MIII type, height 18 cm) containing sterilised sawdust as bedding material (Litalabo, S.P.P.S., Argenteuil, France) and paper as cage-enrichment (Enviro-dri, Wm. Lillico & Son (Wonham Mill Ltd.), Surrey, UK). During the acclimation period the animals were housed in groups in Macrolon cages (MIV type).
- Diet: pelleted rodent diet (SM R/M-Z from SSNIFF Spezialdiäten GmbH, Soest, Germany), ad libitum
- Water: tap water, ad libitum
- Acclimation period: at least 5 days
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19.6-21.2
- Humidity (%): 39-62
- Air changes (per hr): 15
- Photoperiod (hrs dark / hrs light): 12/12
Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- TEST SITE
- Area of exposure: the back of the animals; approximately 25 cm² for males and 18 cm² for females
- % coverage: 10
- Type of wrap if used: the test substance was held in contact with the skin with a dressing, consisting of a surgical gauze patch (Surgy 1D) covered with aluminium foil and Coben elastic bandage, respectively. A piece of Micropore tape was used to fix the bandage in females only.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): the skin was cleaned using tap water
- Time after start of exposure: 24 h
TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 2000 mg/kg bw
- Constant volume or concentration used: yes, the dose volume was calculated as dose level (g/kg) / density (g/mL) - Duration of exposure:
- 24 h
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5
- Control animals:
- other: an untreated, adjacent skin area served as the control
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: the animals were observed twice daily for mortality; the body weight was recorded on Day 1 (prior to dosing), 8 and 15.
- Necropsy of survivors performed: yes, on Day 15 the animals were subjected to necropsy and all gross macroscopical abnormalities were recorded
- Other examinations performed: clinical signs were observed at periodic intervals on the day of dosing (day 1) and once daily thereafter, until sacrifice. The time of onset, degree and duration were recorded and the symptoms graded:
Maximum grade 4: grading slight (1) to very severe (4)
Maximum grade 3: grading slight (1) to severe (3)
Maximum grade 1: presence is scored (1)
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- There was no mortality during the study period (see Table 1).
- Clinical signs:
- other: Piloerection was observed from 4 h - day 2 after dosing in 2/5 males (see Table 2). Chromodacryorrhoea (excessive secretion of a reddish-brown liquid from the eyes) (grade 1) was observed in 3/5 males 2-4 hours after dosing. No systemic clinical signs of
- Gross pathology:
- The necropsy and histopathological examination did not reveal substance-related findings.
- Other findings:
- - Other observations: On the treated skin area, erythema was observed for up to 4 days during Day 3-7 in 3/5 females. Scales or scabs (grade 1) were noted on the treated skin area in 5/5 females and 3/5 males for up to 9 days during Day 7-15 of the observation period.
