Abstract
Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a common and serious disease with unclear pathogenesis and recurrent symptoms. Hedyotis diffusa Willd (HDW) has been recognized for its potential in managing various chronic inflammatory diseases. This research aimed to interrogate the mechanism of HDW in treating CP/CPPS. Complete Freund Adjuvant (CFA) and LPS were utilized to establish the rat and cell models of CP/CPPS. Results showed that HDW decreased levels of inflammation-related factors in CP rat prostate tissue and LPS-elicited RWPE-1 cell injury model. Moreover, HDW administration impaired oxidative stress in the prostate and RWPE-1 cells. In addition, HDW treatment activated the NRF2/ARE signaling in rat prostate tissue and cell models. Interestingly, NRF2/ARE pathway inhibitor ML385 reversed the inhibition effects of cell apoptosis, inflammation, and oxidative stress triggered by HDW. In summary, HDW alleviated inflammation and oxidative stress by activating NRF2/ARE signaling in CP/CPPS rat model and human prostate epithelial cell injury model.

Abstract
The concept of pain encompasses a complex interplay of sensory and emotional experiences associated with actual or potential tissue damage. Accurately describing and localizing pain, whether acute or chronic, mild or severe, poses a challenge due to its diverse manifestations. Understanding the underlying origins and mechanisms of these pain variations is crucial for effective management and pharmacological interventions. Derived from a wide spectrum of species, including snakes, arthropods, mollusks, and vertebrates, animal venoms have emerged as abundant repositories of potential biomolecules exhibiting analgesic properties across a broad spectrum of pain models. This review focuses on highlighting the most promising venom-derived toxins investigated as potential prototypes for analgesic drugs. The discussion further encompasses research prospects, challenges in advancing analgesics, and the practical application of venom-derived toxins. As the field continues its evolution, tapping into the latent potential of these natural bioactive compounds holds the key to pioneering approaches in pain management and treatment. Therefore, animal toxins present countless possibilities for treating pain caused by different diseases. The development of new analgesic drugs from toxins is one of the directions that therapy must follow, and it seems to be moving forward by recommending the composition of multimodal therapy to combat pain.

Abstract
Objectives To explore the effects of the Shuangshi Tonglin (SSTL) capsule on CP/CPPS and reveal the therapeutic mechanisms. Methods A CP/CPPS rat-model group received an intraprostatic injection of CFA. SSTL capsule were administered daily by oral gavage at doses of 1.25, 2.5, and 5.0 g/kg for 28 days. Pain threshold tests were performed, and prostate and blood samples were collected. We performed histological analysis of the prostate tissue and immunohistochemical analysis of TNF-α and COX-2. Measure the TNF-α levels, detect antioxidant levels in serum and prostate tissue, and evaluate the expression of proteins with the AMPK/SIRT-1 and MAPK signalling pathways. Results After SSTL capsule treatment, all animals exhibited an increased mechanical pain threshold in the lower abdomen, decreased inflammation in the stroma, and reduced histological structural damage. Inflammation was reduced through the observed decrease in the levels of various inflammatory factors, as well as in the increase of the levels of MDA, p-AMPK, and SIRT-1. The suppression of IKKβ, p-P38, p-ERK and p-JNK was also observed. Conclusions SSTL capsule treatment decreased inflammation in the stroma and reduced histological structural damage. It improved CP/CPPS symptoms by inhibiting oxidative stress and inflammation. Our study indicates that the SSTL capsule is an effective treatment for prostatitis.

Low-dose melittin is safe for intravitreal administration and ameliorates inflammation in an experimental model of uveitis. CURRENT RESEARCH IN PHARMACOLOGY AND DRUG DISCOVERY 2022; 3:100107. [PMID: 35647524 PMCID: PMC9130091 DOI: 10.1016/j.crphar.2022.100107] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 04/24/2022] [Accepted: 04/29/2022] [Indexed: 11/26/2022] Open
Abstract
Uveitis is a group of sight-threatening ocular inflammatory disorders, whose mainstay of therapy is associated with severe adverse events, prompting the investigation of alternative treatments. The peptide melittin (MEL) is the major component of Apis mellifera bee venom and presents anti-inflammatory and antiangiogenic activities, with possible application in ophthalmology. This work aims to investigate the potential of intravitreal MEL in the treatment of ocular diseases involving inflammatory processes, especially uveitis. Safety of MEL was assessed in retinal cells, chick embryo chorioallantoic membranes, and rats. MEL at concentrations safe for intravitreal administration showed an antiangiogenic activity in the chorioallantoic membrane model comparable to bevacizumab, used as positive control. A protective anti-inflammatory effect in retinal cells stimulated with lipopolysaccharide (LPS) was also observed, without toxic effects. Finally, rats with bacille Calmette-Guerin- (BCG) induced uveitis treated with intravitreal MEL showed attenuated disease progression and improvement of clinical, morphological, and functional parameters, in addition to decreased levels of proinflammatory mediators in the posterior segment of the eye. These effects were comparable to the response observed with corticosteroid treatment. Therefore, MEL presents adequate safety profile for intraocular administration and has therapeutic potential as an anti-inflammatory and antiangiogenic agent for ocular diseases. Melittin at low concentration is safe for intravitreal administration. The antiangiogenic effect of melittin on the chorioallantoic membrane model is comparable to bevacizumab. Melittin protects retinal cells from inflammatory response induced by lipopolysaccharide. Melittin improves clinical, functional and morphological signs of inflammation in rats with BCG-induced uveitis.

Abstract
Mesenchymal stem cells (MSCs) own the capacity to secrete trophic factors as exosomes which play significant roles in regulating the functions of other cells and preventing inflammation. Due to the inflammatory process in chronic non-bacterial prostatitis (CNP) and the ambiguity in the treatment of this disease, the present study was aimed to investigate the therapeutic use of adipose-derived MSC exosomes in an animal model of CNP. MSCs were first isolated from rat subcutaneous adipose tissue, and exosomes were extracted from them. Specific features of exosomes were characterized by a scanning electron microscope, western blot technique, and Dynamic Light Scattering methods. To establish CNP in rats, intraprostatic injection of Freund's complete adjuvant was done. After confirmation of prostatitis, intraprostatic injections of exosomes were performed for treatment. Histological evaluation revealed that treatment with exosomes resulted in a relative improvement of lesions caused by CNP. The expression of p-NF-κB and p-IκBα proteins along with inflammatory markers was significantly increased in the CNP group, which treatment with exosomes significantly reduced their expression as well as IL-1β and TNF-α proteins. The antioxidant effects of exosomes were also determined by significantly regulating glutathione peroxidase and superoxide dismutase activity and malondialdehyde levels in these animals. Our results cautiously suggest the therapeutic effects of MSC-derived exosomes against CNP-induced prostatitis through their antioxidant and anti-inflammatory activities, which should be further considered in the future.

Abstract
Melittin, the main venom component of the European Honeybee, is a cationic linear peptide-amide of 26 amino acid residues with the sequence: GIGAVLKVLTTGLPALISWIKRKRQQ-NH2. Melittin binds to lipid bilayer membranes, folds into amphipathic α-helical secondary structure and disrupts the permeability barrier. Since melittin was first described, a remarkable array of activities and potential applications in biology and medicine have been described. Melittin is also a favorite model system for biophysicists to study the structure, folding and function of peptides and proteins in membranes. Melittin has also been used as a template for the evolution of new activities in membranes. Here we overview the rich history of scientific research into the many activities of melittin and outline exciting future applications.

Abstract
Bee venom (BV) is a complex natural toxin that contains various pharmaceutical compounds. Bee venom acupuncture (BVA), involving a BV injection into a certain acupuncture point, has been utilized to relieve a range of pain conditions. Regardless of whether pain is caused by disease or injury, if not effectively treated, pain can exert a detrimental effect on all aspects of life. In the past decade, many researchers have investigated the anti-nociceptive effects of BVA through clinical use and experimental evaluation. This report reviews the existing knowledge on the analgesic effects of BVA, focusing on musculoskeletal pain, inflammatory pain and neuropathic pain, and its analgesic mechanisms. Although further clinical trials are needed to clinical application of experimental results, this review will contribute to the standardization and generalization of BVA.

Abstract
AIM To establish a new inflammatory animal model of meibomian gland dysfunction (MGD) in C57BL/6 mice. METHODS C57BL/6 mice were randomly divided into complete Freund's adjuvant (CFA) group (14 animals, 14 eyes), naphthazolin hydrochloride (NH) group (14 animals, 14 eyes) and control group (14 animals, 14 eyes). In CFA group, CFA was used in eyelid conjunctiva injection; in NH group, NH eye drops were used twice a day; control group was injected with equal dose of saline at the same time point and same site with animals in CFA group. The meibomian gland orifices score (MGOS) was evaluated on a scale of 0 to 3 in the middle five meibomian gland orifices of the upper and lower eyelid using slit lamp. After the successful induction of each animal model, intense pulsed light (IPL) was introduced on each mouse in CFA and NH group. Oil red O (ORO), hematoxylin and eosin (H&E) staining were performed before and after successful induction of CFA, NH and control group. RESULTS At 12wk after CFA injection, inflammatory cell infiltration and fiber necrosis was observed, with acinar density and duct dilatation significantly lower compared with control group. In NH group, the meibomian gland acini were relatively smaller and deformed compared with control group, the number of meibomian gland acini was also slightly lower. No inflammatory cell or fiber necrosis was observed in NH group. After three times of IPL treatment (5/10 mice in each group, and the other 5 mice served as non-IPL control), MGOS was significantly lower in IPL-treated mice in NH group (P<0.01). After three times of IPL treatment, the MGOS of NH group was significantly lower than that in the CFA group (P<0.01). CONCLUSION We develop a novel animal model that studies the role of inflammation in the development of MGD and IPL treatment. This model indicates that persistent inflammatory state may be the cause of MGD and weaken the therapeutic effect of IPL.

Abstract
Bee venom (BV) is usually associated with pain since, when humans are stung by bees, local inflammation and even an allergic reaction can be produced. BV has been traditionally used in ancient medicine and in acupuncture. It consists of a mixture of substances, principally of proteins and peptides, including enzymes as well as other types of molecules in a very low concentration. Melittin and phospholipase A2 (PLA2) are the most abundant and studied compounds of BV. Literature of the main biological activities exerted by BV shows that most studies focuses on the comprehension and test of anti-inflammatory effects and its mechanisms of action. Other properties such as antioxidant, antimicrobial, neuroprotective or antitumor effects have also been assessed, both in vitro and in vivo. Moreover, human trials are necessary to confirm those clinical applications. However, notwithstanding the therapeutic potential of BV, there are certain problems regarding its safety and the possible appearance of adverse effects. On this perspective, new approaches have been developed to avoid these complications. This manuscript is aimed at reviewing the actual knowledge on BV components and its associated biological activities as well as the latest advances on this subject.

Abstract
BACKGROUND Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is an intractable problem of the urogenital system. The aetiopathogenesis and effective treatments for CP/CPPS are needed to be untangled. Pirfenidone is a molecule that exhibits anti-inflammatory, antifibrotic, and antioxidative stress capacities in a variety of animal experiments and clinical trials. This study was aimed to investigate the therapeutic effect of pirfenidone on CP/CPPS and to identify the mechanism responsible for it. METHODS A CP/CPPS model was induced in rats by intraprostatic injection of complete Freund's adjuvant (CFA). Blood and prostatic tissues were harvested for assessment after the administration of pirfenidone or vehicle for 4 weeks. RESULTS The findings revealed that pirfenidone significantly ameliorated chronic pelvic pain and inhibited prostatic inflammation and fibrosis. Further study found that pirfenidone suppressed the expression of proinflammatory mediators, including tumor necrosis factor-α, interleukin-1β (IL-1β), IL-6, IL-8. Pirfenidone exhibited a potent antioxidant capacity through improving the activities of glutathione, catalase, total superoxide dismutase, and reducing the production of malondialdehyde. Furthermore, pirfenidone also facilitated the polarization of M2 macrophages and suppressed the activation of the nuclear factor-κB (NF-κB) signaling pathway. CONCLUSIONS Pirfenidone can exert a beneficial effect against CFA-induced CP/CPPS by anti-inflammatory, antioxidative, antifibrotic properties, and the function is mediated at least partly through the M2 polarization of macrophages and the inhibition of NF-κB signaling pathway. These findings suggest that pirfenidone holds promise as a potential therapeutic for the treatment of CP/CPPS.

Abstract
Background Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is identified as a urinary andrological diseases that afflict men due to various discomforts. It is urgent and meaningful to develop the novel and effective treatments as a result of the unclear etiology and dismal therapeutic effect of CP/CPPS. Lycopene exerts a crucial role in numerous chronic inflammatory diseases owing to its potent antioxidant capacity. Objective This study aimed to observe the effect of lycopene on CP/CPPS and to explore the underlying mechanisms. Materials and Methods A CP/CPPS model with complete Freund's adjuvant was established in this study. Afterward, intragastric lycopene or corn oil was administered daily for 4 consecutive weeks. Finally, the cardiac blood and prostate tissue samples were collected from rats to carry out related evaluation and testing. Results It was found in this study that lycopene alleviated changes in prostate histopathology compared with those in the complete Freund's adjuvant‐induced CP/CPPS model rats without lycopene treatment. Furthermore, lycopene was suggested to reduce the levels of chemokines MCP1 and MIP‐1α, down‐regulate the expression levels of cytokines (such as TNFα, IL‐1β, IL‐2, and IL‐6), and up‐regulate those of CAT, GSH‐PX, and T‐SOD, decrease that of malondialdehyde. Moreover, it also inhibited the phosphorylation of MAPKs, NF‐κB, and enhanced phosphorylation of the Nrf2 in the CP/CPPS rat model. Discussion and Conclusions The findings in this study suggest that lycopene exerts potent anti‐ CP/CPPS Seffects through alleviating inflammatory response and oxidative stress, which is probably attributed to the interaction of NF‐κB, MAPKs, and Nrf2 signaling pathways in rats. As a natural antioxidant, lycopene may serve as a promising pharmaceutical preparation for treating CP/CPPS.

Use of Selected Carbon Nanoparticles as Melittin Carriers for MCF-7 and MDA-MB-231 Human Breast Cancer Cells. MATERIALS 2019; 13:ma13010090. [PMID: 31878020 PMCID: PMC6981792 DOI: 10.3390/ma13010090] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Revised: 12/13/2019] [Accepted: 12/19/2019] [Indexed: 12/16/2022]
Abstract
Despite advanced techniques in medicine, breast cancer caused the deaths of 627,000 women in 2018. Melittin, the main component of bee venom, has lytic properties for many types of cells, including cancer cells. To increase its toxic effect, carbon nanoparticles, graphene oxide, pristine graphene, and diamond were used as carriers of melittin to breast cancer cells. To date, the effects of carbon nanoparticles as carriers of melittin on cancer cells have not been studied. The present study was carried out on MCF-7 and MDA-MB-231 cell lines. The investigation consisted of structural analysis of complexes using transmission electron microscopy, zeta potential measurements, evaluation of cell morphology, assessment of cell viability and membrane integrity, investigation of reactive oxygen species production, and investigation of mitochondrial membrane potential. Cell death was examined by flow cytometry and a membrane test for 43 apoptotic proteins. The results indicate that melittin complex with nanographene oxide has a stronger toxic effect on breast cancer cells than melittin alone. Moreover, nanodiamonds can protect cells against the lytic effects of melittin. All complexes reduced, but not completely eliminated the level of necrosis, compared to melittin. Thus, results suggest that the use of carbon nanoparticles as carriers for melittin may find use in medicine in the future.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a frustrating syndrome. The pathogenesis and state of the art treatment of CP/CPPS are not known. A wide variety of therapies including anti-inflammatories, antibiotics, alpha-blockers, neuropathic pain modulators, and 5α-reductase inhibitors are in practice. These treatment strategies focus on alleviating symptoms in specific domains without treating root-cause and therapeutic outcome is far from satisfactory. We review the literature on current pharmacological treatments for CP/CPPS in detail and suggest future perspectives to modify the treatment strategies. We suggest that introducing novel treatment strategies such as gene editing, and Tregs expressing chimeric receptors may improve the treatment outcomes by inducing immune tolerance and controlling expression of pro-inflammatory cytokines.

Involvement of the anti-inflammatory, anti-apoptotic, and anti-secretory activity of bee venom in its therapeutic effects on acetylsalicylic acid-induced gastric ulceration in rats. Toxicology 2019; 419:11-23. [PMID: 30885738 DOI: 10.1016/j.tox.2019.03.003] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2018] [Revised: 02/21/2019] [Accepted: 03/12/2019] [Indexed: 12/11/2022]
Abstract
Acetylsalicylic acid (ASA) is the most highly consumed pharmaceutical product worldwide. Importantly, gastrointestinal ulceration due to ASA is a major complication. Hence, the present work aimed to examine, for the first time, the healing properties of bee venom (BV) in acute gastric ulceration induced by ASA. Forty adult male Sprague-Dawley rats were divided into four groups that received distilled water only, ASA (500 mg/kg BW) twice daily for 3 days, ASA for 3 days followed by BV (2 mg/kg BW) for 7 days, or ASA for 3 days followed by ranitidine hydrochloride (50 mg/kg BW) for 7 days. Haematological analysis, haemostatic evaluation, and inflammatory marker estimation were performed. Rat stomachs were collected for ulcer scoring, gene expression analysis, oxidative stress assays, histopathological and immunohistochemical examinations, and tissue eosinophil scoring. The results revealed that BV markedly decreased the ulcer index, pro-inflammatory cytokine levels, malondialdehyde levels, BAX distribution, caspase-3 expression, and tissue eosinophil levels. Additionally, significant increases in antioxidant enzymes and heat shock protein 70 localization in gastric tissue were evident following BV treatment after ASA exposure. Also, BV has been found to attenuate the haematological, haemostatic, and histopathological alterations induced by ASA. Our findings collectively indicate that the gastroprotective effect of BV against ASA-induced ulceration in rats is mediated by its antioxidant, anti-inflammatory, anti-apoptotic, and anti-secretory properties.

Abstract
Background: Bronchogenic carcinoma (lung cancer) is one of the leading causes of death. Although many compounds isolated from natural products have been used to treat it, drug resistance is a serious problem, and alternative anti-cancer drugs are required. Here, melittin from Apis mellifera venom was used, and its effects on bronchogenic carcinoma cell proliferation and tumour-associated macrophage differentiation were evaluated. Methods: The half maximal inhibitory concentration (IC50) of melittin was measured by MTT. Cell death was observed by annexin V and propidium iodide (PI) co-staining followed by flow cytometry. Cell cycle arrest was revealed by PI staining and flow cytometry. To investigate the tumour microenvironment, differentiation of circulating monocytes (THP-1) into tumour-associated macrophages (TAMs) was assayed by sandwich-ELISA and interleukin (IL)-10 levels were determined. Cell proliferation and migration was observed by flat plate colony formation. Secretion of vascular endothelial growth factor (VEGF) was detected by ELISA. The change in expression levels of CatS, Bcl-2, and MADD was measured by quantitative RT-PCR. Results: Melittin was significantly more cytotoxic (p < 0.01) to human bronchogenic carcinoma cells (ChaGo-K1) than to the control human lung fibroblasts (Wi-38) cells. At 2.5 μM, melittin caused ChaGo-K1 cells to undergo apoptosis and cell cycle arrest at the G1 phase. The IL-10 levels showed that melittin significantly inhibited the differentiation of THP-1 cells into TAMs (p < 0.05) and reduced the number of colonies formed in the treated ChaGo-K1 cells compared to the untreated cells. However, melittin did not affect angiogenesis in ChaGo-K1 cells. Unlike MADD, Bcl-2 was up-regulated significantly (p < 0.05) in melittin-treated ChaGo-K1 cells. Conclusion: Melittin can be used as an alternative agent for lung cancer treatment because of its cytotoxicity against ChaGo-K1 cells and the inhibition of differentiation of THP-1 cells into TAMs.

Abstract
Bee venom acupuncture is a form of acupuncture in which bee venom is applied to the tips of acupuncture needles, stingers are extracted from bees, or bees are held with an instrument exposing the stinger, and applied to acupoints on the skin. Bee venom is a complex substance consisting of multiple anti-inflammatory compounds such as melittin, adolapin, apamin. Other substances such as phospholipase A2 can be anti-inflammatory in low concentrations and pro-inflammatory in others. However, bee venom also contains proinflammatory substances, melittin, mast cell degranulation peptide 401, and histamine. Nevertheless, in small studies, bee venom acupuncture has been used in man to successfully treat a number of musculoskeletal diseases such as lumbar disc disease, osteoarthritis of the knee, rheumatoid arthritis, adhesive capsulitis, and lateral epicondylitis. Bee venom acupuncture can also alleviate neurological conditions, including peripheral neuropathies, stroke and Parkinson's Disease. The treatment has even been piloted in one series to alleviate depression. An important concern is the safety of bee venom. Bee venom can cause anaphylaxis, and several deaths have been reported in patients who successfully received the therapy prior to the adverse event. While the incidence of adverse events is unknown, the number of published reports of toxicity is small. Refining bee venom to remove harmful substances may potentially limit its toxicity. New uses for bee venom acupuncture may also be considered.

Abstract
Melittin (MLT), as a natural active biomolecule, can penetrate the tumor cell membrane to play a role in cancer treatment and will attract more attention in future development of antitumor drugs. The main component of natural bee venom MLT was modified by introducing a pH-sensitive amide bond between the 2,3-dimethyl maleimide (DMMA) and the lysine (Lys) of MLT (MLT-DMMA). MLT and its corresponding modified peptide MLT-DMMA were used for antitumor and biocompatibility validation. The biomaterial characteristics were tested by MALDI-TOF MS, 1H NMR, IUPAC and HPLC, cell viability, hemolytic and animal experiment safety evaluation. Compared with the primary melittin, the modified peptide showed decreased surface charge and low cytotoxicity in physiological conditions. Moreover, cell assays confirmed the acid-activated conversion of amide bond resulting in adequate safety during delivery and timely antitumor activity in tumor lesions. Thus, MLT-DMMA provided a feasible platform to improve the targeted and safe antitumor applications.

Abstract
BACKGROUND Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a common disease of urology, of which the pathogenesis and therapy remain to be further elucidated. Quercetin has been reported to improve the symptoms of CP/CPPS patients. We aimed to verify the therapeutic effect of quercetin on CP/CPPS and identify the mechanism responsible for it. METHODS A novel CP/CPPS model induced with Complete Freund Adjuvant in Sprague Dawley rats was established and the prostates and blood specimens were harvested for further measurement after oral administration of quercetin for 4 weeks. RESULTS Increased prostate index and infiltration of lymphocytes, up-regulated expression of IL-1β, IL-2, IL-6, IL-17A, MCP1, and TNFα, decreased T-SOD, CAT, GSH-PX, and increased MDA, enhanced phosphorylation of NF-κB, P38, ERK1/2, and SAPK/JNK were detected in CP/CPPS rat model. Quercetin was identified to ameliorate the histo-pathologic changes, decrease the expression of pro-inflammatory cytokines IL-1β, IL-2, IL-6, IL-17A, MCP1, and TNFα, improve anti-oxidant capacity, and suppress the phosphorylation of NF-κB and MAPKs. CONCLUSIONS Quercetin has specific protective effect on CP/CPPS, which is mediated by anti-inflammation, anti-oxidation, and at least partly through NF-κB and MAPK signaling pathways.

Abstract
Paclitaxel, a chemotherapy drug for solid tumors, induces peripheral painful neuropathy. Bee venom acupuncture (BVA) has been reported to have potent analgesic effects, which are known to be mediated by activation of spinal α-adrenergic receptor. Here, we investigated the effect of BVA on mechanical hyperalgesia and spinal neuronal hyperexcitation induced by paclitaxel. The role of spinal α-adrenergic receptor subtypes in the analgesic effect of BVA was also observed. Administration of paclitaxel (total 8 mg/kg, intraperitoneal) on four alternate days (days 0, 2, 4, and 6) induced significant mechanical hyperalgesic signs, measured using a von Frey filament. BVA (1 mg/kg, ST36) relieved this mechanical hyperalgesia for at least two hours, and suppressed the hyperexcitation in spinal wide dynamic range neurons evoked by press or pinch stimulation. Both melittin (0.5 mg/kg, ST36) and phospholipase A2 (0.12 mg/kg, ST36) were shown to play an important part in this analgesic effect of the BVA, as they significantly attenuated the pain. Intrathecal pretreatment with the α₂-adrenergic receptor antagonist (idazoxan, 50 µg), but not α₁-adrenergic receptor antagonist (prazosin, 30 µg), blocked the analgesic effect of BVA. These results suggest that BVA has potent suppressive effects against paclitaxel-induced neuropathic pain, which were mediated by spinal α₂-adrenergic receptor.

Abstract
PURPOSE Bladder smooth muscle cell death accompanied by hyperplasia and hypertrophy, as induced by inflammation, is the primary cause for poor bladder function. There are emerging evidences on the role of chronic inflammation as a factor involved in carcinogenesis and progression. We aim to determine the bladder smooth muscle pathological changes and dysfunction in chronic prostatitis (CP), to investigate whether resveratrol can improve the urinary dysfunction and the role of c-kit/SCF pathway, that has been associated with the smooth muscle carcinogenesis. METHOD Rat model of CP was established via subcutaneous injections of DPT vaccine and subsequently treated with resveratrol. H&E staining was performed to identify the histopathological changes in prostates and bladders. Western blotting and immunohistochemical staining examined the expression level of C-kit, stem cell factor (SCF), Sirt1, apoptosis associated proteins. RESULTS the model group exhibited severe diffuse chronic inflammation, characterized by leukocyte infiltration and papillary frond protrusion into the gland cavities, and a notable increase in prostatic epithelial height. Meanwhile, bladder muscle arranged in disorder with fracture, and cells appeared atypia. The activity of C-kit/SCF was up-regulated, the carcinogenesis associated proteins are dysregulated significantly in CP rats. Resveratrol treatment significantly improved these factors by Sirt1 activation. CONCLUSIONS activated c-kit/SCF and bladder muscle carcinogenesis were involved in the pathological processes of CP, which was improved after resveratrol treatment via the downregulation of c-kit/SCF by activating Sirt1.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the most common urologic morbidity in men younger than 50 years and is characterized by a diverse range of pain and inflammatory symptoms, both in type and severity, that involve the region of the pelvis, perineum, scrotum, rectum, testes, penis, and lower back. In most patients, pain is accompanied by inflammation in the absence of an invading infectious agent. Since CP/CPPS etiology is still not well established, available therapeutic options for patients are far from satisfactory for either physicians or patients. During the past two decades, chronic inflammation has been deeply explored as the cause of CP/CPPS. In this review article, we summarize the current knowledge regarding immunological mechanisms underlying chronic pelvic pain and prostate inflammation in CP/CPPS. Cumulative evidence obtained from both human disease and animal models indicate that several factors may trigger chronic inflammation in the form of autoimmunity against prostate, fostering chronic prostate recruitment of Th1 cells, and different other leukocytes, including mast cells, which might be the main actors in the consequent development of chronic pelvic pain. Thus, the local inflammatory milieu and the secretion of inflammatory mediators may induce neural sensitization leading to chronic pelvic pain development. Although scientific advances are encouraging, additional studies are urgently needed to establish the relationship between prostatitis development, mast cell recruitment to the prostate, and the precise mechanisms by which they would induce pelvic pain.
