AIM To investigate the roles of p38 mitogen-activated protein kinase (p38 MAPK) in the cardiovascular and behavioral responses induced by intracerebral ventricular injection (i.c.v.) of interleukin-1 beta (IL-1 beta) or footshock. METHODS We examined the effects of p38 MAPK on mean artery blood pressure (mABP), heart rate (HR), and motor activity (MA)(More)
It has been shown that intracerebroventricular injection of urotensin II (UII)-induced hypotensive and bradycardiac responses. Here, we tested the cardiovascular roles of UII in different brain areas by microinjection of UII into the A1 and A2 areas (noradrenergic cells found in the lower part of the medulla that have been designated either A1 or A2 areas),(More)
OBJECTIVE To investigate the effect of central interleukin-1beta (IL-1beta) on motor behavioral responses in novelty stress rats. METHODS The novelty stress was elicited by novel environmental stimuli with novelty stress box. The intracerebrolventricular (ICV) cannula and microinjection were performed with rat brain stereotaxic system. Movement behaviors(More)
In order to study the protective effects on motor and cognitive function by inhibiting IL-1β as delayed as 24h after global ischemia, we designed behavioral testing protocol and histology detection after 10 min transient global ischemia followed by IL-1β or its antibody intracerebroventricular injection. We found benefit of IL-1β antibody treatment 24h(More)
The effects of interleukin-1beta in the paraventricular nucleus or caudal arcuate nucleus on hypertensive and tachycardiac responses induced by excitation of the central amygdaloid nucleus were studied. We observed that microinjection of sodium glutamate into central amygdaloid nucleus resulted in hypertension and tachycardia. Microinjection of(More)
