Pharmacokinetics and sedative effects of intramuscular medetomidine in domestic sheep
Journal of Veterinary Pharmacology and Therapeutics, 2003Intramuscular (i.m.) administration of medetomidine (MED) may avoid the severe pressor effects caused by peripheral actions of MED associated with intravenous (i.v.) dosing. The purpose of this study was to determine the pharmacokinetics, the time course of sedation and occurence of hypoxaemia after i.m. administration of MED in domestic sheep. The MED

Retinal Photoreceptor Fine Structure in the Domestic Sheep

In the sheep retina the photoreceptors are readily differentiated and adequately described by the classical terminology of rods and cones. Rods are more numerous then cones. They appear as tall slender cells measuring 45–50 µm in length and
