BACKGROUND In this study, we investigated the effects of treatment with chronic antihypertensive drugs (clonidine, methyldopa, amlodipine, ramipril and rilmenidine) on oxidant-antioxidant parameters and toxic effects on DNA in rat uterus tissue. In addition, uterus tissues were examined histopathologically. MATERIALS AND METHODS A total of 36 albino Wistar rats were divided into the following...
AIM The aim of this study was to investigate the effects of pioglitazone and losartan pre-treatment on the aortic contractile response to the alpha-1 agonist, phenylephrine, and the alpha-2 agonist, clonidine, in L-NAME-induced hypertensive, STZ-induced diabetic, and hypertensive diabetic rats. METHODS Male Wistar rats were randomly allocated to four groups: control, diabetic (DM), hypertensi...
1. The modulation by alpha 2-adrenoceptors of the jaw-opening reflex (digastric electromyographic responses) elicited by orofacial electrical stimulation (OF-JOR) in pentobarbitone anaesthetized rats was investigated. 2. Increasing doses of clonidine (0.1-1000 micrograms kg-1, i.v.) reduced, in a dose-dependent manner until abolition, the amplitude and duration of the OF-JOR and increased the l...
INTRODUCTION Sedation is an essential part of paediatric critical care. Midazolam, often in combination with opioids, is the current gold standard drug. However, as it is a far-from-ideal agent, clonidine is increasingly being used in children. This drug is prescribed off-label for this indication, as many drugs in paediatrics are. Therefore, the CLOSED trial aims to provide data on the pharmac...
OBJECTIVE To assess the effect of oral clonidine as a premedicative drug on 24-hour urine output, urine specific gravity, plasma renin activity as well as serum and urine electrolytes levels. METHODS This prospective study was carried out on 60 women aged 20-40 years old undergoing repair of cystocoele-rectocoele perineorraphy under general anaesthesia in Asali Hospital in 2004 in Khorramabad...
In a prospective, double-blind, controlled study the efficacy of clonidine was assessed in children, with respect to sedation, intubation response, and recovery. Fifty children, aged 4-12 years, undergoing general anesthesia were studied. Twenty-five children (group I) received oral diazepam) 0.2 mg/kg and another 25 children (group II) received oral clonidine 3 micrograms/kg, 90-120 minutes be...
Background: Many intrathecal adjuvants are being used with local anesthetics to prolong the intraoperative anesthesia and postoperative analgesia. Clonidine buprenorphine known potentiate effects of anesthestics. Aims Objectives: This study was designed compare duration analgesia as well sensory motor block onset, hemodynamic changes, perioperative complications between clonidine when an adjuva...
in this study, the effect of α-adrenoceptor agents on imipramine-induced antinociception was investigated using formalin test. intraperitoneal (i.p.) administration of imipramine at different doses (10-80 mg/kg) induced antinociception in both phases of formalin test. in addition, intracerebroventricular (i.c.v.) injection of imipramine (1, 5, and 10 µg/rat) did not elicit any effect, although ...
The effects of clonidine on substance P (SP) binding was investigated using rat brain and spinal cord membrane preparations preincubated with various concentrations of clonidine. [3H]SP specific binding in the spinal cord was significantly decreased with 10(-4) M clonidine, but no effect on binding was seen in the brain. Scatchard analysis of SP binding indicated that Bmax was significantly dep...
conclusions there were no statistical differences between oral clonidine and intravenous lidocaine regarding attenuation of hemodynamic responses after tracheal intubation in controlled hypertensive patients, although the rate of complications including mouth dryness, bradycardia, and orthostatic hypotension was significantly higher in the clonidine group before induction of anesthesia. results...
