Background: Piper sarmentosum Roxb. (Cha Phul) is a plant in the Piperaceae family which the whole plant is used as an expectorant and the leaf as a carminative. Many extracts from the plants in this family show anti-nociceptive, anti-inflammatory and antipyretic activities in various animal models.

Objective: To investigate the anti-inflammatory, anti-nociceptive and antipyretic effects of the ethanol extract from P. sarmentosum root.

Material And Method: In vivo study.

Results: P. sarmentosum extract significantly inhibited ethyl phenylpropiolate-induced ear edema as well as carrageenan-induced hind paw edema in rats. The extract reduced transudative and granuloma weights of the chronic inflammatory model using the cotton pellet-induced granuloma formation in rats. The extract exerted a pronounced inhibitory activity on the early phase and late phase of the formalin test in mice. In addition, the extract elicited an antipyretic activity on yeast-induced hyperthermia in rats.

Conclusion: P. sarmentosum extract possessed anti-inflammatory, anti-nociceptive and antipyretic activities.

Efficacy of vagus nerve stimulation in gastrointestinal disorders: a systematic review.

Dysfunction of the vagus nerve has been suggested as a contributing factor in various gastrointestinal disorders, prompting interest in vagus nerve stimulation (VNS) as a non-pharmacological therapy. We performed a systematic review to determine the efficacy of invasive and non-invasive VNS in gastrointestinal disorders, including inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), functional dyspepsia (FD), functional constipation, gastroesophageal reflux disease, and gastroparesis. We applied a systematic search of the literature in the PubMed, Embase, Web of Science, and Cochrane Library databases in order to identify studies comparing VNS with an adequate control condition (sham stimulation) in patients with gastrointestinal disorders.

Thiadiazine thione (THTT) has gained significant interest owing to its pharmacological potentials, particularly its antiparasitic and anti-inflammatory properties. Leishmaniasis is a clinical syndrome caused by infection with species and is associated with an inflammatory response and nociception. The available treatments against leishmaniasis are inadequate, as they are associated with high cost, toxicity, and increased resistance.

Trigeminal neuralgia (TN) is chronic pain caused by damage to the somatosensorial system on the trigeminal nerve or its branches, which involves peripheral and central dysfunction pain pathways. Trigeminal pain triggers disruptive pain in regions of the face, including within and around the mouth. Besides clinical experiences, translating the language of suffering into scientific terminology presents substantial challenges.

Introduction And Objective: The aim of the study was to investigate the effect of bee venom on the activity of two analgesics: ketoprofen (a non-steroidal anti-inflammatory drug) and tramadol (an opioid drug) in the acute thermal pain model (hot-plate test) in mice.

Material And Methods: Linear regression analysis was used to evaluate the dose-response relationship between logarithms of drug doses and their resultant maximum possible anti-nociceptive effects in the mouse hot-plate test. Doses that increased the anti-nociceptive effect by 20% (ED values) for bee venom, ketoprofen and tramadol, and their combination were calculated from linear equations.
