Background & Aim: Eugenia caryophyllata well known as Clove is a tree from Myrtaceae family that several parts of this plant traditionally used in dental care as an analgesic. This study aimed to assess the chemical composition, anti-inflammatory and anti-nociceptive activities of the essential oil extracted from Clove buds. Experimental: The essential oil of Clove buds (EOC) was extr...

We investigated the anti-nociceptive effect of Excoecaria agallocha (E.agallocha) against chemically and thermally induced nociception, Albino mice received a dose of 10, 15, 20, or 25 mg/kg of alkaline chloroform fraction (Alk-CF) of E.agallocha by oral administration. Compared with controls, Alk-CF decreased the writhing numbers (P<0.01) in a dose dependent manner. Further we determined that,...

The soluble epoxide hydrolase (sEH) enzyme regulates the levels of endogenous epoxygenated fatty acid (EFA) lipid metabolites by rapidly degrading these molecules. The EFAs have pleiotropic biological activities including the modulation of nociceptive signaling. Recent findings indicate that the EFAs, in particular the arachidonic acid (AA) derived epoxyeicosatrienoic acids (EETs), the docosahe...

It has long been established that histamine plays a role as a mediator of inflammation. From numerous studies, it has been well known that the amine has many pharmacological actions on a variety of organs. To evaluate the role of histamine in pain perception, we generated HDC knockout mice using a gene targeting method. Histamine is a hydrophilic autacoid, and in most tissues it is stored and s...

AIM To evaluate the anti-nociceptive activity of 7-methoxy coumarin isolated from ethyl acetate fraction of the alcoholic extract of Eupatorium triplinerve Vahl. MATERIALS AND METHODS The shade dried leaves of E. triplinerve were extracted with ethyl alcohol and the extract was condensed. This extract was fractionated with n-hexane, ethyl acetate, and n-butanol. The ethyl acetate fraction was...

introduction: mineral trioxide aggregate (mta) is an endodontic material with different clinical applications e.g. root-end filling, pulp capping and perforation repair.  it has been reported to possess antimicrobial and antifungal activities. the aim of this study was to examine the effect of white mta on formalin-induced hyperalgesia in a rat with inflammatory pain. materials and methods: inf...

OBJECTIVE To test the hypothesis that dry needle stimulation of a myofascial trigger point (sensitive locus) evokes segmental anti-nociceptive effects. DESIGN Double-blind randomized controlled trial. SUBJECTS Forty subjects (21 males, 19 females). METHODS Test subjects received intramuscular dry needle puncture to a right supraspinatus trigger point (C4,5); controls received sham intramu...

Oxysophocarpine (OSC) is an alkaloid extracted from Siphocampylus verticillatus. The aim of this study was to investigate the anti-nociceptive effects of OSC through systemic and intracerebroventricular administration in mice. Moreover, to evaluate its effectiveness and mechanism of action, this study investigated whether OSC altered the expression of γ-aminobutyric acid type A α1 (GABAAα1) rec...
