A note on the electrically transmurally stimulated isolated trachea of the guinea-pig

open access: yes, 1964
The isolated trachea of the guinea-pig was stimulated electrically transmurally to give a biphasic response. The initial contraction was abolished by atropine and was rapidly succeeded by relaxation which was blocked by low concentrations of dichloro ...

Morphometric analysis of postnatal lung development in the gray short‐tailed opossum (Monodelphis domestica): An ultrastructural study

open access: yesThe Anatomical Record, EarlyView.
Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.

Effects of 3-methylhistamine and phenylethylamine on histamine action on isolated guinea-pig trachea rings

open access: yes, 2011
It is well known that histamine produces constriction via H 1 receptors and decreases tracheal smooth muscle tone via H 2 and H 3 receptors. In addition, it has already been reported that 3-methylhistamine and phenylethylamine are competitive antagonists

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

open access: yesThe Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Resveratrol activity on guinea pig isolated trachea from normal and albumin-sensitized animals.

open access: yes, 1988
The relaxant effect of resveratrol on guinea pig isolated trachea (EC50 = 100 microM) was not due to interactions with histaminergic or cholinergic systems, but appeared to be influenced by beta-blockers, indomethacin and mepacrine.

EVIDENCE THAT ADRENERGIC NERVES ARE RESPONSIBLE FOR THE ACTIVE UPTAKE OF NORADRENALINE IN THE GUINEA‐PIG ISOLATED TRACHEA

open access: yes, 1975
6‐Hydroxydopamine (50 mg/kg, i.p.) was given to guinea‐pigs to destroy the adrenergic nerve terminals in the trachea. The destruction was demonstrated by fluorescence histochemistry, which showed a marked loss of beaded fluorescent terminal fibres and by

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

open access: yesThe Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.
