Cuminum cyminum Linn. (Umbelliferae) is a plant, which has been used as a toothache remedy in folk medicine of Iran. In this study, the potential anti-nociceptive and anti-inflammatory activities of the fruit essential oil of C. cyminum has been evaluated in chemical (formalin test) and thermal (tail-flick test) models of nociception and formalin model of acute inflammation in rats and mice. Th...

  The paragigantocellularis (PGi) nucleus constitutes a large portion of the ventral pontomedullary reticular formation. Neurons within the PGi have been implicated in a variety of functions including cardiovascular regulation, respiratory control, pain and analgesia. Investigators have demonstrated that electrical stimulation and microinjection of L-glutamate into the PGi produce antinocicepti...

the development of combination therapy is a coherent approach in severe pain treatment. the present study investigated the antinociceptive effect of pregabalin alone and in combination with tramadol in acute pain modeling. therefore, three groups of male mice received either pregabalin (1 to 400 mg/kg), tramadol (10 to 80 mg/kg) or their combination intraperitoneally. then latency time, maximum...

calendula of.cinalis (asteraceae) is widely used in traditional medicine as an anti-in.ammatory agent and has also been reported to have anti-bacterial, anti-fungal and anti-viral activities.  sesquiterpene glycosides, saponins, triol, triterpenes and .avonoids are observed in its composition. the present study was designed to evaluate the antinociceptive effect of hydro-alcoholic extract of ca...

Role of ethanolic extract of P. granatum seeds on central nervous system (CNS) in animal models of elevated plus maze test, barbiturate-induced sleeping time, tail suspension test, hot-plate and tail-flick test was studied. P. granatum (PG) extract was administered to young and aged mice at single doses of 100, 250 and 500 mg/kg, perorally while diazepam (1 mg/kg), morphine (5 mg/kg) and imipra...

Zingiber officinale Roscoe, commonly known as ginger, is a traditional herb used to treat various disorders. In this study, we evaluated potential pharmacological effects of ethanolic extracts of Z. Officinale with respect to central nervous system (CNS) activity in mice. Role of ethanolic extract of ginger on CNS activity in mice was studied using models of elevated plus maze test, barbiturate...

Microinjection of kappa opioid receptor (KOR) agonists into the rostral ventromedial medulla (RVM) attenuates mu-opioid receptor mediated antinociception and stress-induced analgesia, yet is also reported to have an analgesic effect. To determine how KOR agonists produce both antinociceptive and antianalgesic actions within the RVM, the KOR agonist U69593 was microinjected directly into the RVM...

Özet Amaç: Tek başına veya birlikte sistemik olarak verilen tramadol ve gabapentinin farelerde akut ağrıda olası antinosiseptif etklerini araştırmaktır. Gereç ve Yöntem: Hayvan etik komitesinin onayı sonrası; 96 BALB/c albino dişi fare 12 gruba ayrıldı: (I) Enjeksiyon yapılmaksızın kontrol grubu, (II) salin uygulanan kontrol grubu, (III)-(IV) tramadol 10 mg/kg veya 30 mg/kg uygulanan gruplar, (...
