Three studies were undertaken to reevaluate (1) whether there is a peripheral component in the reduction of sympathetic activity caused by centrally acting drugs; and (2) whether the antihypertensive effect of these drugs is due entirely to this reduction. Plasma growth hormone and norepinephrine concentrations were used as respective markers of central a-adrenoceptor stimulation and peripheral...

A partial recovery of locomotor functions has been shown in spinal cord-transected (Tx) cats after regular treadmill training and repeated administration of clonidine, an 2-adrenoreceptor agonist. However, clonidine has generally failed to show prolocomotor effects in other models (e.g., rat or mudpuppy in vitro-isolated spinal cord preparations). The reasons for this discrepancy remain unclear...

Background and Objectives: Epidural anesthesia is a popular technique for providing lower limb surgeries. Dexmedetomidine Clonidine are known to enhance the effect of local anaesthetics. The purpose this study was compare impact dexmedetomidine clonidine on onset duration epidural anaesthesia using bupivacaine. Methods: After IEC approval, prospective, randomized, double blinded conducted 60 AS...

in this paper, we calculate the eccentric connectivity index and the eccentricity sequence of two infinite classes of fullerenes with 50 + 10k and 60 + 12k (k in n) carbon atoms.

The effect of intravenous clonidine on pentagastrin-induced gastric acid secretion has been studied in conscious dogs with Heidenhain pouches. Dose-dependent enhancement of secretion was found in response to clonidine (5-20 mu/kg). Clonidine (20 mug/kg) increased the maximal secretory rate to pentagastrin to a value not significantly different from the maximal response to histamine.

Zero-dimensional fullerenes can modulate the biological behavior of a variety of cell lines. However, the effects and molecular mechanisms of proliferation and cardiomyogenic differentiation in brown adipose-derived stem cells (BADSCs) are still unclear. In this study, we report the initial biological effects of fullerene-C60 on BADSCs at different concentrations. Results suggest that fullerene...

In an open, randomized, cross-over study the hypotensive action and side effects of clonidine-chlorthalidone and methyldopa-chlorthalidone combinations were compared. The diastolic morning blood pressure could be reduced to 95 mm. Hg or below in significantly more patients with clonidine than with methyldopa. Side effects, however, were more commonly encountered during the clonidine than during...

In this study, three lines of evidence suggest a role for α(2)-adrenoreceptors in rat pup odor-preference learning: olfactory bulb infusions of the α(2)-antagonist, yohimbine, prevents learning; the α(2)-agonist, clonidine, paired with odor, induces learning; and subthreshold clonidine paired with subthreshold β-adrenoceptor activation also recruits learning. Increased mitral cell layer pCREB o...
