| Quantitative Results | ||
| 1 of 2 | Effect | behavioral symtoms |
| Route of Application | intracerebroventricular | |
| Kind of Dosing (Ecotoxicology) | title comp. dissolved in 0.85percent saline containing 0.1percent Evans Blue solution; admin. in a volume of 10 ml using a microsyringe into lateral ventricle | |
| Method (Ecotoxicology) | layer chicks admin. with title comp. alone or in combination with HA; behavioral symptoms (active wakefulness (1), standing/sitting motionless with eyes opened (2), standing motionless with eyes closed (3), sleeping posture (4)) obsd. for 10 min | |
| Results | title comp. showed significant effects in active wakefulness and sleeping posture; combination effects of title comp. and HA were similar to title comp. alone; table | |
| 2 of 2 | Effect (Ecotoxicology) | behavioral symtoms |
| Further Details (Ecotoxicology) | control: saline; further investigations with selective and non-selective nitric oxide synthase (NOS) inhibitors administered i.c.v. | |
| Results | title comp. significantly induced spontaneous activity; effect may be linked to constitutive NOS rather than inducible NOS in brain |
