Amaranthus tricolor whole plants are used by folk medicinal practitioners of Bangladesh for treatment of pain, anaemia, dysentery, skin diseases, diabetes, and as a blood purifier. Thus far, no scientific studies have evaluated the antihyperglycaemic and antinociceptive effects of the plant. The present study was carried out to evaluate the possible glucose tolerance efficacy of methanolic extr...

been detected in central nervous system of rodents, nonhuman primates and human based on radioligand binding studies. KOR agonists may have pharmacotherapeutic potential in the treatment of pain or hyperalgesia and in the management of psychostimulant addiction. However, the clinical application of selective KOR agonists, such as ethylketocyclazocine and U-50488, has been limited by the occurre...

A hydroethanolic extract (HE-ext) of Bacopa monnieri (BM) was studied for antinociceptive effect in the animal models of acetic-acid-induced writhing test and antilocomotive effect in mice. Standard centrally-acting analgesic, morphine (MP), and peripherally-acting one, diclofenac (Diclo), were also tested along with the extract for comparison. The extract exhibited significant antinociceptiv...

Foeniculum vulgare (fennel) has been widely used in traditional medicine for treatment of variousdiseases including pediatric colic. This study was designed to assess the antinociceptive effects of aqueousextract of F. vulgare on visceral pain and possible involvement of opioidergic, serotonergic, adrenergic andhistaminergic systems. The results of this study showed that aqueous extract of F. v...

One of the most important functions of the opioid system is the control of pain. Among the three main opioid receptor classes (μ, δ, κ), the μ (MOR) is the main type targeted for pharmacotherapy of pain. Opioid analgesics such as morphine, oxycodone and fentanyl are agonists at the MOR and are the mainstay for the treatment of moderate-to-severe pain. However, adverse effects related to opioid ...

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...

pistacia vera l., a member of anacardiaceae family, has been used for sedation and analgesia in traditional medicine. in this study, the antinociceptive and anti-inflammatory effects as well as acute toxicity of the aqueous and ethanolic extracts of p. vera leaves were investigated in mice. the antinociceptive activity was studied using hot plate and writhing tests. the effect of the extracts a...

BACKGROUND Tramadol is an analgesic drug, and its mechanism of action is believed to be mediated by the mu-opioid receptor. A further action of tramadol has been identified as blocking the reuptake of serotonin (5-HT). One of the most recently identified subtypes of 5-HT receptor is the 5-HT7 receptor. Thus, the authors aimed to examine the potential role of serotonergic descending bulbospinal ...

Purpose: To investigate the antinociceptive effect of Asplenium nidus ethanolic extract (ANEE) using a Caenorhabditis elegans model.Methods: Sublethality assay was performed on ANEE to determine experimental concentrations be used for assays. Antinociceptive in C. investigated mechanosensation assays four treatment timepoints within 72 hours. index (AI) calculated cells treated with as well mor...
