The emetic reflex in a reptile (Crocodylus porosus).
The emetic (vomiting) reflex in a crocodilian, Crocodylus porosus, was characterised for the first time using the plant alkaloid veratrine (5 mg kg(-)(1) i.v. or i.p.) as an emetic stimulus. The latency to the onset of vomiting was 8.0+/-0.9 min (mean +/- s.e.m., N=5 animals). Vomiting was preceded by a clearly defined set of prodromal behaviours including, in temporal sequence, rhythmic contra...
متن کاملEmetic Reflex Arc Revealed Gene c&s in the Cat Expression Immediate-early
The organization of the central neuronal circuitry that produces vomiting was explored by mapping the distribution of c-fos protein (Fos)-like immunoreactivity (FLI) as a monitor of functional activity. The brainstem and spinal cord were examined in cats administered multiple emetic drugs (cisplatin, lobeline, protoveratrine, naloxone, apomorphine) or control saline injections. Some animals wer...

mester, there was one malformed foetus reported. However, irradiation and other cytotoxics had also been used in this case. Animal experiments have shown that one of the most sensitive periods of inducing foetal abnormalities with 6-mercaptopurine is at implantation (Thiersch, 1954). However, in humans it is rare for the mother to be receiving cytotoxic drugs at the time of conception. The pres...

assumes control over the ventricles. When this happens, two types of auriculo-ventricular rhythm may arise. One is called A-V nodal rhythm and is recognized by the inverted P waves, which are as a rule either abnormally close to the QRS complex or may follow it. The second type of auriculo-ventricular rhythm is known as A-V dissociation, characterized by the rate of the ventricular contractions...
متن کاملOculo-auriculo-vertebral (Goldenhar's) syndrome.
Goldenhar's syndrome (Goldenhar, I952) consists of epibulbar dermoids or lipodermoids, auricular appendages, pretragal blind fistulas, and vertebral anomalies. A number of other deformities associated with this condition have been summarized by Bowen, Collum, and Rees (I97I). Our case is presented because of the presence of an aberrant salivary gland in the nose. This complication has not been ...
