Electrical responses of smooth muscle cells during cholinergic vasodilation in the rabbit saphenous artery.
Isolated smooth muscle tissues of the rabbit saphenous artery precontracted with norepinephrine (NE) were relaxed by acetylcholine (ACh, greater than 10(-7) M) or oxotremorine (greater than 10(-7) M), through the activation of muscarinic receptors, only when the endothelial cells were intact. ACh (greater than 10(-7) M) transiently hyperpolarized the membrane (1-4 minutes) with an associated de...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولNoradrenergic and cholinergic modulation of olfactory bulb sensory processing
Neuromodulation in sensory perception serves important functions such as regulation of signal to noise ratio, attention, and modulation of learning and memory. Neuromodulators in specific sensory areas often have highly similar cellular, but distinct behavioral effects. To address this issue, we here review the function and role of two neuromodulators, acetylcholine (Ach) and noradrenaline (NE)...
متن کاملSUBTYPES OF α1-ADRENOCEPTORS IN RABBIT SAPHENOUS VEIN
We investigated the a,-adrenoceptor subtypes of rabbit saphenous vein which has a mixed functional population of α1 and α2 -adrenoceptors. Lateral saphenous veins were obtained from male rabbits weighing 3.20-4 kg, which were killed by overdose with pentobarbitone sodium (i.v. injection). They were easily dissected out and placed in cold, oxygenated modified Krebs-Henselite solution (Krebs)...
متن کاملModulation of norepinephrine release from sympathetic neurons of the rabbit aorta by prejunctional prostanoid receptors.
The pharmacological properties and subtypes of prostanoid receptors involved in the prejunctional modulation of [(3)H]norepinephrine release from sympathetic neurons were studied using isolated rabbit aorta. Rings preincubated with [(3)H]norepinephrine were washed with physiological salt solution that contained cocaine plus corticosterone, uptake(1) and uptake(2) inhibitors, respectively, and r...
