Cholinergic blockade and tonic immobility in chickens
To investigate the effects of cholinergic blockade on duration of tonic immobility (TI) and habituation to handling and the TI testing procedure, two groups of cockerel chicks were tested following injection with scopolamine or saline. One week later half of each group was given a second test for TI following injection with saline or scopolamine. Results indicated that scopolamine significantly...
متن کاملThe biphasic mystery: why a biphasic shock is more effective than a monophasic shock for defibrillation.
We demonstrate that a biphasic shock is more effective than a monophasic shock at eliminating reentrant electrical activity in an ionic model of cardiac ventricular electrical activity. This effectiveness results from early hyperpolarization that enhances the recovery of sodium inactivation, thereby enabling earlier activation of recovering cells. The effect can be seen easily in a model of a s...
متن کاملTonic Shock Induces Detachment of Giardia lamblia
BACKGROUND The parasite Giardia lamblia must remain attached to the host small intestine in order to proliferate and subsequently cause disease. However, little is known about the factors that may cause detachment in vivo, such as changes in the aqueous environment. Osmolality within the proximal small intestine can vary by nearly an order of magnitude between host fed and fasted states, while ...
متن کاملSeptic shock: treating more than just blood pressure.
Technology: Anti-inflammatory therapy for the treatment of septic shock Use: Sepsis or septic shock, which occurs when the host’s response to infection is excessive, is the fourth leading cause of long-stay intensive care admissions. Death may occur despite antimicrobial therapy if the host response to infection is either excessive or insufficient (Fig. 1); in fact, mortality has been reported ...
