introduction: feverfew (tanacetum parthenium) (t.p.) is widely used in folk medicine to treat many diseases. we reported the analgesic effect of t.p. flower and leaf previously. present study is designed to find the mechanism underlying the anti-nociceptive effect of the aqueous extract of t.p. flower. method: based on our previous study, the dose 50 mg/kg i.p. of the t.p. aqueous extract had a...

F MOTAMEDI, S SEMNANIAN,

Transcutaneous electrical nerve stimulation (TENS) is an analgesia inducing method with increasing applications in clinical procedures. In this study we tried to evaluate the role of the adrenergic system and its different adrenoceptor subtypes in TENS-induced analgesia. Two types of low and high frequency electrical stimuli were used in rats through needle electrodes, inserted at the base ...

Background and purpose: The adrenergic system is known to have modulatory influence on anxiety-related behaviour both in human and animals. Dorsal hippocampus is an important brain site in modulation of neurotransmittery and neuroendocrinology of anxiety. The present study, was designed to evaluate the interactions between adrenergic and opioidergic systems in dorsal hippocampus on anxiety. Ma...

Introduction: Prolonged exposure to electromagnetic fields (EMF) influences digestive system specially its motility. The present study was performed in order to study the effects of exposure to low frequency EMF on the adrenergic system of large intestine. Methods: In this experimental study, thirty adult male rats were divided into three groups: First group (experimental) inc...

In this study the effect of adrenergic receptor agonists and antagonists on physostigmine induced yawning was investigated. Intraperitoneal injection of different doses of physostigmine (0.03, 0.05, 0.1 and 0.2 mg/kg) caused yawning in white rats. The greatest response was seen at a dose of 0.2 mg/kg physostigmine. Phenylephrine, an α1 agonist, and clonidine, an α2 agonist, led to a decrease in...
