Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lotus corniculatus L. (Fabaceae) traditionally used in Persian folk medicine to heal peritoneal inflammation and back pain. AIM OF THE STUDY To explore the antinociceptive (acute pain) and anti-neuropathic (chronic pain) activities of Lotus corniculatus leaves essential oil (LCEO) in addition to uncovering the possible mechanisms of antinociception. MATERIALS AND METHODS LCEO as well as the pure oleanolic acid (OA) compound, were assayed for their effects on acute (formalin induced paw licking test or FIPT) and chronic (cervical contusion injury models on the fifth cervical vertebra or CCS; 14-day intervals) pain. The possible involvements of NO-cGMP-K+ channel, TRPV, dopamine, cannabinoid, PPAR, adrenergic, and opioid mechanisms in the antinociceptive activity of LCEO have studied by formalin test. The levels of p53 and inflammatory markers were measured using a streptavidin biotin immune peroxidase complex and ELISA methods, respectively. RESULTS The LCEO and OA exerted antinociceptive activity in the first-phase of FIPT. Pretreatment with antagonists of TRPV1, dopamine D2, cannabinoid type1 and 2, and NO-cGMP-K+ channel blockers (glibenclamide, L-NAME and methylene blue) attenuated the antinociceptive effect of LCEO in FIPT. In addition, LCEO and OA meaningfully reduced hyperalgesia (days 6-14) and mechanical allodynia (days 2-14) in the CCS model. LCEO suppressed the apoptotic marker (p53) in CCS model and also ameliorated IL-2, TNF-α, and IL-1 in the spinal cord. CONCLUSION Finally, LCEO inhibited acute (possibly via the modulation of opioid, TRPV, dopamine, cannabinoid mechanisms as well as NO-cGMP-K+ channel) and chronic pain (via suppressing apoptotic and inflammatory markers) in male rats. The results also suggest that OA has analgesic activity against acute and chronic pain conditions.

Abstract
In the current study, Cnicus benedictus extract was loaded into electrospun gelatin scaffolds for diabetic wound healing applications. Scaffolds were characterized in vitro by mechanical testing, cell culture assays, electron microscopy, cell migration assay, and antibacterial assay. In vivo wound healing study was performed in a rat model of diabetic wound. In vitro studies revealed fibrous architecture of our developed dressings and their anti-inflammatory properties. In addition, Cnicus benedictus extract-loaded wound dressings prevented bacterial penetration. In vivo study showed that wound size reduction, collagen deposition, and epithelial thickness were significantly greater in Cnicus benedictus extract-loaded scaffolds than other groups. Gene expression studies showed that the produced wound dressings significantly upregulated VEGF and IGF genes expression in diabetic wounds.

Abstract
BACKGROUND Chaerophyllum macropodum Boiss. (popularly known as "Jafari farangi kohestani") is a predominant medicinal plant traditionally utilized in the treatments of peritoneal inflammation and headache in Persian folk medicine. Here, we have revealed the anti-neuropathic and anti-nociceptive activities of C. macropodum leaves essential oil (CMEO) in addition to uncovering the possible mechanisms of action. METHODS Formalin-induced paw licking model was used to assess the anti-nociceptive activity of CMEO and its major constituent, terpinolene (TP). The anti-nociceptive activity of these compounds was determined by investigating the roles of various non-opioid and NO-cGMP-K+ channels. Additionally, the anti-neuropathic potential of CMEO and TP was determined using cervical spinal cord contusion/CCS technique. RESULTS The CMEO exerted significant anti-nociceptive activity with a remarkable activity seen in the second phase of formalin-induced paw licking model and this activity were remarkably reversed by pre-treatment of naloxone (an opioid antagonist). Pretreatment with several types of NO-cGMP-potassium channel pathway meaningfully reversed the anti-nociceptive potential of CMEO in phase II of formalin model. Moreover, pre-treatment with several antagonists of non-opioid receptors revealed that only the antagonist of TRPV-1, serotonin type 3, 5-HT2, α2 adrenergic, and CB1 receptors (capsaicin, ondansetron, ketanserin, yohimbine, and SR141716A, respectively) reversed CMEO anti-nociception. CMEO and TP also remarkably reversed hyperalgesia and mechanical allodynia in the CCS technique. CONCLUSION The CMEO exerts anti-nociceptive and anti-neuropathic activities via the modulation of NO-cGMP potassium channel pathway, opioid as well as several non-opioid receptor activity. TP might partly contribute to the observed activities of CMEO.

Abstract
Chronic pain affects approximately one-fifth of people worldwide and reduces quality of life and in some cases, working ability. Ion channels expressed along nociceptive pathways affect neuronal excitability and as a result modulate pain experience. Several ion channels have been identified and investigated as potential targets for new medicines for the treatment of a variety of human diseases, including chronic pain. Voltage-gated channels Na+ and Ca2+ channels, K+ channels, transient receptor potential channels (TRP), purinergic (P2X) channels and acid-sensing ion channels (ASICs) are some examples of ion channels exhibiting altered function or expression in different chronic pain states. Pharmacological approaches are being developed to mitigate dysregulation of these channels as potential treatment options. Since natural compounds of plant origin exert promising biological and pharmacological properties and are believed to possess less adverse effects compared to synthetic drugs, they have been widely studied as treatments for chronic pain for their ability to alter the functional activity of ion channels. A literature review was conducted using Medline, Google Scholar and PubMed, resulted in listing 79 natural compounds/extracts that are reported to interact with ion channels as part of their analgesic mechanism of action. Most in vitro studies utilized electrophysiological techniques to study the effect of natural compounds on ion channels using primary cultures of dorsal root ganglia (DRG) neurons. In vivo studies concentrated on different pain models and were conducted mainly in mice and rats. Proceeding into clinical trials will require further study to develop new, potent and specific ion channel modulators of plant origin.

Abstract
Simultaneous identification and quantification of phenolic acid (chlorogenic acid), sesquiterpene lactone (cnicin), lignan (arctiin), and flavonoids (bracteoside, 6-methoxybracteoside, isokaempferide, and viscosine) in mixed parts of Centaurea benedicta (Syn. Cnicus benedictus) were performed for the first time. The liquid chromatography method showed an adequate performance for the separation of seven compounds. The method was validated for linearity (0.5-100 μg/mL), precision, accuracy, limit of detection (LOD), and limit of quantification (LOQ) as well as robustness. Cnicin and arctiin were detected at concentrations as low as 0.25 µg/mL. Remaining flavonoids and chlorogenic acid were detected at 0.025 μg/mL. The method demonstrated good performance in terms of intra- and inter-day precision (0.1-3.4%), accuracy (98.0-105.0%), lower and upper limits of quantification for all compounds. Analysis of various samples showed considerable variation of 0.9-10.3 mg/g for the marker compound, cnicin. Twenty-one dietary supplements, claiming to contain C. benedictus extract, were analyzed for authenticity. Thirteen (62%) of 21 products showed the presence of all analyzed compounds and were confirmed to contain C. benedictus. A liquid chromatography-tandem mass spectrometry method coupled with electrospray ionization (ESI) is described for the identification of compounds in plant samples. This method involved the use of protonated, deprotonated, and adduct ions for compounds in positive and negative ion modes with extractive ion chromatogram (EIC). The application of liquid chromatography-quadrupole time of flight mass spectrometry (LC-QToF) provided useful information to characterize sixty-four compounds. The developed methods were also applicable for quality assessment of raw materials and dietary supplements containing C. benedictus.

Abstract
INTRODUCTION Using tissue engineering and modifying the tumor microenvironment, three-dimensional (3D) in vitro and in vivo cancer modeling can be performed with appropriate similarity to native. Exosomes derived from different sources have recently been used in cancer studies due to their anticancer effects. In this study, the effect of crab derived exosomes in 2 & 3-dimensional (2& 3D) in vivo models of breast cancer (BC) were investigated and compared with the doxorubicin (DOX). METHODS 2D and 3D models of BC were induced using the chitosan/β-glycerol phosphate hydrogel (Ch/β-GP) and 1 × 106 4T1 cells in the female mice aged 6-8 weeks. 1 mg/ml exosome and 5 mg/kg DOX were injected by intratumoral (IT), intravenous (IV), and intraperitoneal (IP) methods into mice on day 9, 13, and 17 with and without hydrogel as a drug delivery system. After 21 days, the mice were sacrificed, and the tissues (lung, liver, and tumor) were removed. The weight and size of the tumor were measured. Real-time PCR assessed changes of VEGF, Bcl2, and P53 genes expression levels. Nitric oxide (NO) secretion from the cancer 3D model was evaluated by Griess assay. RESULTS AND CONCLUSION Based on the results, the size and weight of tumors in treated groups with exosomes and DOX were reduced significantly (P ≤ 0.001, P ≤ 0.002, P ≤ 0.02) in 2D and 3D models. Changes in VEGF, Bcl2 and P53 gene expression levels were less in the 3D model than in the 2D model. Drug delivery with hydrogel increased tumor inhibition compared to drug injection without hydrogel. Decreased NO secretion was observed in all treatment groups compared to the control group (untreated). Crab exosomes showed anti cancer effects on 2&3D models of BC. 3D model of BC showed greater drug resistance than the 2D model after treating with crab derived exosomes and DOX. 3D model of BC mimics native tumor better than 2D and can be used in cancer studies and for drug screening with greater confidence than 2D model. Also, the use of slow release drug delivery system reduced drug resistance in both models.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Thymus persicus (Roniger ex Reach F.) is an Iranian endemic medicinal plant of which essential oil and various products have numerous food and pharmaceutical applications (headache and fever treatments). OBJECTIVE This modern research included Swiss mice to investigate the anti-nociceptive and anti-neuropathic effects of Thymus persicus aerial parts essential oil (TPEO). MATERIALS AND METHODS To determine TPEO's anti-nociceptive function in the formalin-induced paw licking (FML), researchers looked at the L-arginine/NO/cGMP/KATP channel signaling pathway as well as multiple receptors as with serotonin, morphine, dopamine, and peroxisome proliferator-activated receptors. The CVC or cervical spinal cord contusion exemplar has also been used to induce neuropathic pain. RESULTS TPEO (50, 100, and 150 mg/kg) relative to control mice in the phase-II of FML provided strong antinociception (p < 0.05, p < 0.01, p < 0.001, respectively). Furthermore, methylene blue, glibenclamide, Nω-nitro-L-arginine methyl ester, naloxonazine, nor-binaltorphimine, prazosin, yohimbine, and ondansetron pre-treating restored the TPEO anti-nociceptive activity in the FML (phase-II) exemplar (p < 0.05). In phase-II of the FML exemplar, carvacrol (one of the active components of TPEO) also greatly reduced pain (p < 0.001). Likewise, in CVC mice, TPEO altered mechanical allodynia and hyperalgesia. CONCLUSION It was attained magnificently that TPEO could exerts antinociceptive effects through the involvement of L-arginine/NO/cGMP/KATP signaling pathway, adrenergic, opioid, and serotonin receptors. Moreover, it is demonstrate that anti-neuropathic activity of TPEO may be mediated by inflammatory function.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Iranian/Persian folkloric medicine, Physospermum cornubiense (Shokaran Baghi in Persian) is used for the treatment of pain and inflammation. OBJECTIVE This modern examination included Swiss mice to investigate the anti-neuropathic and anti-nociceptive effects of Physospermum cornubiense essential oil (PCEO). MATERIALS AND METHODS To determine PCEO 's anti-nociceptive function in formalin-induced paw licking (FML) paradigm, researchers looked at the arginine-nitric oxide and potassium channels pathway in addition to involvements of more specific examples of receptors such as adrenergic, opioid, cannabinoid, peroxisome proliferator-activated (PPA), and transient receptor potential vanilloid. The CVC or cervical spinal cord contusion exemplar has also been used to induce neuropathic pain. RESULTS PCEO (450mg/kg) relative to control mice in the phase_ II of FML exemplar provided strong antinociception (p < 0.001). Furthermore, pre-treatments with arginine, glibenclamide, methylene blue, L-NAME, SNP, GW6471, naloxonazine, and GW9662 (p < 0.05) returned the PCEO antinociceptive response in the FML (inflammatory phase) model. Orally limonene administration significantly diminished (p < 0.001) acute pain in inflammatory phase of FML test. Moreover, the von Frey test indicated that both PCEO and limonene could return neuropathic pain (mechanical allodynia) in CVC mice. CONCLUSION The results obtained from this study, together with literature, give evidence of properties of PCEO for therapy of antinociceptive and neuropathic pain.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Iranian folkloric medicine, Bupleurum falcatum L. (Chinese Thoroughwax) has been used as a selective analgesic remedy for several centuries. OBJECTIVE The current research was conducted to explore the anti-nociceptive and anti-allodynic action of Bupleurum falcatum L. roots essential oil (BFEO) in Swiss mice. MATERIALS AND METHODS Formalin-induced paw licking (FIPL) model was applied for exploring of BFEO antinociceptive effects (neurogenic or inflammatory pain). The involvements of L-arginine-NO-cGMP-KATP channel pathway and several receptors such as opioid, peroxisome proliferator-activated (PPA), cannabinoid, transient receptor potential vanilloid, and adrenergic receptors were assesses to detect the anti-nociceptive activity of BFEO. Cervical spinal cord contusion (CSC) paradigm was employed for induction of neuropathic pain. RESULTS BFEO (100 mg/kg), in the FIPL model, produced significant antinociception compared to the control mice (p < 0.01). Furthermore, L-arginine, methylene blue, glibenclamide, naloxonazine, GW9662, and SR141716A pre-treatments restored the BFEO anti-nociceptive effects (p < 0.05) in the FIPL (second phase) test (p < 0.05). Intraperitoneal administration of saikosaponin A (one of the main constituents of BFEO) partially alleviated (p < 0.05) pain in FIPL test. Likewise, in CSC mice, the von Frey assay exhibited that BFEO could alter mechanical allodynia. CONCLUSION Finally, it seems that, in male mice, BFEO has both anti-allodynic and anti-nociceptive effects. The present data also suggest activating the L-arginine-NO-cGMP-KATP channel pathway as well as interaction of opioid, PPA, and cannabinoid receptors in the BFEO anti-nociceptive activities. These results also propose that BFEO could effectively attenuate allodynia in CSC mice.

Abstract
Background and purpose: Kaempferol (KM), a flavonoid, has an anti-inflammatory and anticancer effect and prevents many metabolic diseases. Nonetheless, very few studies have been done on the antinociceptive effects of KM. This research aimed at assessing the involvement of opioids, gamma-aminobutyric acid (GABA) receptors, and inflammatory mediators in the antinociceptive effects of KM in male Wistar rats. Experimental approach: The intracerebroventricular and/or intrathecal administration of the compounds was done for examining their central impacts on the thermal and chemical pain by the tail-flick and formalin paw tests. For assessing the role of opioid and GABA receptors in the possible antinociceptive effects of KM, several antagonists were used. Also, a rotarod test was carried out for assessing motor performance. Findings/Results: The intracerebroventricular and/or intrathecal microinjections of KM (40 μg/rat) had partially antinociceptive effects in the tail-flick test in rats (P < 0.05). In the formalin paw model, the intrathecal microinjection of KM had antinociceptive effects in phase 1 (20 and 40 μg/rat; P < 0.05 and P < 0.01, respectively) and phase 2 (20 and 40 μg/rat; P < 0.01 and P < 0.001, respectively). Using naloxonazine and/or bicuculline approved the involvement of opioid and GABA receptors in the central antinociceptive effects of KM, respectively. Moreover, KM reduced the expression levels of caspase 6, interleukin-1β, tumor necrosis factor-α, and interleukin-6. The antinociceptive effects of KM were not linked to variations in the locomotor activity. Conclusion and implications: It can be concluded that KM has remarkable antinociceptive effects at a spinal level, which is associated with the presence of the inflammatory state. These impacts were undetectable following injections in the lateral ventricle. The possible mechanisms of KM antinociception are possibly linked to various modulatory pathways, including opioid and GABA receptors.
