Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- Male: 2000 mg/kg bw; Number of animals: 5; Number of deaths: 0
Female: 2000 mg/kg bw; Number of animals: 5; Number of deaths: 0 - Clinical signs:
- Signs of toxicity related to dose levels:
The main clinical signs observed were: hypoactivity,
muscular tremors, salivation, palpebral closure,
hypothermia, shallow breathing, piloerection and hunched
posture starting from 30 minutes - 4 hours and lasting up to
6-24 hours after the test article administration.
Sporadic cases of ataxia, reddish nasal discharge,
chromodacryorrhea were also observed.
Recovery of all treated rats was achieved within 24
(females) - 48 hours (males) of treatment.
Low body weight gain was observed in some animals only at
the day 3 weighing. Body weight gain returned to normal at
the subsequent weighing. - Gross pathology:
- Effects on organs:
Terminal autopsy findings were normal.
