BACKGROUND A growing body of evidence suggests that neuroinflammation, which is characterized by infiltration of immune cells, activation of mast cells and glial cells, and production of inflammatory mediators in the peripheral and central nervous systems, plays an important role in the induction and maintenance of chronic pain. Palmitoylethanolamide (PEA), which is a type of N-acylethanolamide...

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...

Background & Aim: The use of anti-nociceptive and anti-inflammatory drugs in clinical medicine is necessary and unavoidable. Since the use of synthetic drugs is associated with numerous side effects, the application of complementary therapies such as herbal medicine can accompany with less side effects while having anti-inflammatory and analgesic properties. Satureja<e...

backround and aim: in the present time, analgesic and anti-inflammatory drugs such as nonseroidal anti-inflammatory drugs and opioid compounds are used for the releif of pain, but due to their side effects and economical issues, the significance of research on finding analgesic drugs with less side effects and their ability to substitute these synthetic drugs and substituting newer analgesic co...

Pain is fundamentally unpleasant and induces a negative affective state. The affective component of pain is mediated by circuits that are distinct from those mediating the sensory-discriminative component. Here, we have investigated the role of prostaglandins in the affective dimension of pain using a rodent pain assay based on conditioned place aversion to formalin injection, an inflammatory n...

Objective: Crocin and safranal are the main components of saffron, and have many biological functions such as anti-inflammatory and antioxidant activities. In the present study, we investigated the effects of crocin, safranal, morphine, diclofenac and naloxone in combined and separately on formalin-induced orofacial pain in rats. Materials and Methods: Subcutaneous injection of a diluted formal...

Microglial cells are responsible for immune surveillance within the CNS. They respond to noxious stimuli by releasing inflammatory mediators and mounting an effective inflammatory response. This is followed by release of anti-inflammatory mediators and resolution of the inflammatory response. Alterations to this delicate process may lead to tissue damage, neuroinflammation, and neurodegeneratio...
