Newest firstSynthetic cannabinoids (SCs), such as K2 or spice, are potent, intoxicating, laboratory-produced compounds designed to mimic Δ9-tetrahydrocannabinol (Δ9-THC). Some SCs are full agonists that bind to cannabinoid receptors in the endocannabinoid system with significantly higher affinity than Δ9-THC, often causing more intense and unpredictable effects, including cardiovascular, respiratory, and neuropsychiatric comp…
Open article record in new tab ↗Rationale/objectives Targeting cannabinoid receptor type 1 (CB1R) has shown promise for treating opioid withdrawal symptoms. This study aimed to investigate the efficacy of a specific CB1R negative allosteric modulator (NAM), Org27569, in reducing both naloxone-precipitated and protracted withdrawal symptoms in oxycodone-dependent mice. Methods Mice received escalating doses of oxycodone (9-33 mg/kg IP) or saline…
Open article record in new tab ↗The TRPM8 channel, a temperature-sensitive ion channel, plays a crucial role in various physiological processes, particularly in the modulation of inflammation and nociception. Although electroacupuncture (EA) is a recognized analgesic treatment for pain conditions, its interaction with TRPM8 remains underexplored. This study aims to determine TRPM8's role in EA-induced analgesia using a murine model of inflammato…
In this work we strived to determine whether endocannabinoid system activity could account for the differences in acute inflammatory pain sensitivity in mouse lines selected for high (HA) and low (LA) swim-stress-induced analgesia (SSIA). Mice received intraplantar injections of 5% formalin and the intensity of nocifensive behaviours was scored. To assess the contribution of the endocannabinoid system, mice were i…
Introduction Tolerance (TOL) and physical dependence (PD) constitute important limitations of opioid therapy. The aim of our study was to validate research tools to investigate TOL and PD and to characterize the interactions between opioid (OR) and cannabinoid (CB) receptors in these processes in the GI tract. Methods TOL was assessed through the comparison of morphine ability to inhibit electrically evoked smooth…
Substances of abuse include alcohol, nicotine, cannabinoids, opioids, sedatives, volatile solvents, stimulants, and hallucinogens. With the increasing prevalence of drug abuse in India, intensivists are likely to encounter more cases of intentional and accidental poisoning due to drugs of abuse. We aim to sensitize the intensivists to challenges involved in diagnosing and treating poisoning with drugs of abuse. We…
Pain is susceptible to various cognitive factors. Suppression of pain by hunger is well known, but the effect of food intake after fasting (i.e. refeeding) on pain remains unknown. In the present study, we examined whether inflammatory pain behavior is affected by 24 h fasting and 2 h refeeding. In formalin-induced acute inflammatory pain model, fasting suppressed pain behavior only in the second phase and the ana…
Open article record in new tab ↗The present study examined the potential antinociceptive activity of C18 5-HT (βN-octadecanoyl-5-hydroxytryptamide) using chemical and thermal nociception models in mice. Orally administered C18 5-HT (0.1, 1 and 10 mg/kg) produced significant dose-dependent antinociceptive effects in formalin-, capsaicin- and glutamate-induced licking models. This compound also induced a significant increase in the response to the…
