JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116882. [PMID: 37422100 DOI: 10.1016/j.jep.2023.116882] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 07/03/2023] [Accepted: 07/05/2023] [Indexed: 07/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As a traditional Chinese anti-emetic formula, Xiao-Ban-Xia decoction (XBXD) was recorded in Golden Chamber, and has promising anti-emetic effect on chemotherapy-induced nausea and vomiting (CINV). AIM OF THE STUDY This study aimed to determine whether the underlying mechanism of XBXD against CINV is correlated to the restoration of cisplatin-induced PINK1/Parkin mediated mitophagy deficiency and mitigation of gastrointestinal inflammation. MATERIALS AND METHODS The rat pica model was established by intraperitoneal injection of cisplatin 6 mg/kg. The daily kaolin consumption, food intake and body weight were recorded every 24 h. The pathological damage of gastric antrum and ileum were observed by hematoxylin-eosin staining. The levels of serum reactive oxygen species (ROS), interleukin-1β (IL-1β) and interleukin-1β (IL-18) were detected by ELISA. The expression of microtubule-associated protein 1 light chain 3 (LC3) in gastric antrum and ileum was detected by Immunofluorescence staining. The levels of LC3II, P62/SQSTM1, PTEN-induced putative protein kinases (PINK1), E3 ubiquitin ligase (Parkin), AMP-dependent protein kinases (AMPK), phosphorylated AMPK (p-AMPK), nuclear factor erythroid 2-related factor (Nrf2) and kelch like ECH Associated Protein 1 (Keap1) in gastric antrum and ileum were assayed by western blotting. RESULTS At 24 h and 72 h following cisplatin challenge, XBXD inhibited cisplatin-induced elevation of kaolin consumption, and improved the daily food intake and body weight loss in rats. Cisplatin-induced gastrointestinal histopathological damages were alleviated, and serum levels of ROS, IL-1β and IL-18 increases were mitigated following XBXD treatments. In gastric antrum and ileum, XBXD activated AMPK-Nrf2 signaling pathway and restored cisplatin-induced PINK1/Parkin mediated mitophagy deficiency. CONCLUSIONS XBXD significantly ameliorated CINV in a cisplatin-induced rat pica model. The underlying anti-emetic mechanism of XBXD might be related to the activation of AMPK-Nrf2 signaling pathway and the restoration of cisplatin-induced PINK1/Parkin-mediated mitophagy deficiency in the gastrointestinal tract.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116970.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Xiaobanxia Decoction (XBXD), a traditional antiemetic formula, is effective in preventing chemotherapy-induced nausea and vomiting (CINV), but its underlying mechanism has not been fully clarified. AIM OF THE STUDY To investigate whether the antiemetic mechanisms of XBXD against CINV is associated with the reduction of GSDME-mediated pyroptosis and the alleviation of gastrointestinal inflammation induced by cisplatin. MATERIALS AND METHODS We established the in vivo pica rat model and the in vitro small intestinal epithelial cell (IEC-6 cell) injury model by cisplatin challenge. The levels of ROS, IL-1β, IL-18, HMGB1 were measured by ELISA. The histopathological changes of gastrointestinal (GI) tissues were examined by HE staining. The expression and localization of GSDME in GI tissues were determined by IHC. The GSDME mRNA expression in GI tissues was determined by RT-PCR. The IEC-6 cell viability was detected by CCK-8. The morphology of IEC-6 cells was observed by optical microscope and scanning electron microscopy. Pyroptosis was examined using Hoechst33342/PI staining. The intracellular ROS levels were measured with the fluorescent probe DCFH-DA. The expression levels of JNK, p-JNK, Bax, Bcl-2, caspase-9, caspase-3 and GSDME in GI tissues and IEC-6 cells were determined by WB. RESULTS We found that the cumulative kaolin intake (pica behavior, analogous to emesis) significantly increased in cisplatin-treated rats, accompanied by significant inflammatory pathological changes of GI tissues. XBXD decreased the cumulative kaolin intake and alleviated GI inflammation in cisplatin-treated rats by inhibiting the activation of the ROS/JNK/Bax signaling pathway and by reducing GSDME-mediated pyroptosis. Additionally, cisplatin damaged IEC-6 cells by activating GSDME-dependent pyroptosis. XBXD reduced GSDME-mediated IEC-6 cell pyroptotic death by regulating the ROS/JNK/Bax signaling pathway. CONCLUSIONS This study suggested that GSDME-mediated pyroptosis greatly contributes to the occurrence of CINV, and suppressing GSDME-mediated pyroptosis is the important antiemetic mechanism of XBXD.

Ullah I, Ayaz M. A re-consideration of neural/receptor mechanisms in chemotherapy-induced nausea and vomiting: current scenario and future perspective. Pharmacol Rep 2023; 75:1126-1137.

Abstract
The neural mechanisms and the receptors behind the course of chemotherapy-induced nausea and vomiting (CINV) are well described and considered mechanistically multifactorial, whereas the neurobiology of nausea is not completely understood yet. Some of the anti-neoplastic medications like cisplatin result in biphasic vomiting response. The acute phase of vomiting is triggered mainly via the release of serotonin from the enterochromaffin (EC) cells in the gastrointestinal tract (GIT) and results in stimulation of dorsal vagal complex (DVC) of the vomiting center and the vomiting is initiated by downward communication to the gut via vagal efferents. Agonism of 5HT3 receptors is majorly involved in the mediation of the acute phase. Therefore, antagonists at 5HT3 receptors are effective in the management of acute-phase vomiting episodes. Likewise, Dopamine type 2 (D2) receptors, dopamine neurotransmitter, Muscarinic receptors (M3), GLP1 receptors, and histaminergic receptors (H1) are also implicated in the vomiting act as well. In continuation, Cannabinoid type 1 (CB1) receptors are also recommended and included in the guidelines as agonism of presynaptically located CB1 receptors inhibits the release of excitatory neurotransmitters responsible for vomiting initiation. The delayed phase involves the release of "Substance P" in the gut and results in the stimulation of neurokinin-1 (NK1) receptors centrally in the area postrema (AP) and nucleus tractus solitarius (NTS), subsequently the vomiting response. The current understanding is the existence of overlapping mechanisms of neurotransmitters, serotonin, dopamine, and substance P throughout the time course of CINV. Furthermore, the emetic neurotransmitters are released via calcium ion (Ca++)-dependent mechanisms, implicating the molecular targets of intracellular Ca++ signaling in emetic circuitry. The current review entails the neurobiology of nausea and vomiting induced by cancer chemotherapeutic agents and the recent approaches in the management.

Abstract
Chemotherapy-induced nausea and vomiting (CINV), a common side effect in antineoplastic treatment, dramatically decreases the quality of life as well as the compliance of cancer patients. Although numerous antiemetic agents have been used for CINV treatment, its adverse reactions as well as its inadequate control toward delayed emesis still limit its clinical usage. Traditional Chinese medicine (TCM), with more than 3,000 years of practical history in Asia, has been successfully applied to mitigate chemotherapy-induced side effects. Growing attention is drawn to the antiemetic effect of TCM against CINV due to its promising therapeutic property and higher safety recently. In this review, we summarize the classic antiemetic TCM-based treatment and its mechanisms, so as to provide a theoretical basis for further investigations of TCM against CINV in the future.

Abstract
Background and Aims: Chemotherapy-induced acute and delayed emesis involves the activation of multiple pathways, with 5-hydroxytryptamine (5-HT; serotonin) playing a major role in the initial response. Substance P tachykinin NK1 receptor antagonists can reduce emesis induced by disparate emetic challenges and therefore have a clinical utility as broad inhibitory anti-emetic drugs. In the present studies, we investigate the broad inhibitory anti-emetic profile of a relatively new NK1 receptor antagonist, netupitant, alone or in combination with the long acting 5-HT3 receptor antagonist, palonosetron, for a potential to reduce emesis in ferrets and shrews. Materials and Methods: Ferrets were pretreated with netupitant and/or palonosetron, and then administered apomorphine (0.125 mg/kg, s.c.), morphine (0.5 mg/kg, s.c.), ipecacuanha (1.2 mg/kg, p.o.), copper sulfate (100 mg/kg, intragastric), or cisplatin (5–10 mg/kg, i.p.); in other studies netupitant was administered to Suncus murinus before motion (4 cm horizontal displacement, 2 Hz for 10 min). Results: Netupitant (3 mg/kg, p.o.) abolished apomorphine-, morphine-, ipecacuanha- and copper sulfate-induced emesis. Lower doses of netupitant (0.03–0.3 mg/kg, p.o.) dose-dependently reduced cisplatin (10 mg/kg, i.p.)-induced emesis in an acute (8 h) model, and motion-induced emesis in S. murinus. In a ferret cisplatin (5 mg/kg, i.p.)-induced acute and delayed emesis model, netupitant administered once at 3 mg/kg, p.o., abolished the first 24 h response and reduced the 24–72 h response by 94.6%; the reduction was markedly superior to the effect of a three times per day administration of ondansetron (1 mg/kg, i.p.). A single administration of netupitant (1 mg/kg, p.o.) plus palonosetron (0.1 mg/kg, p.o.) combined with dexamethasone (1 mg/kg, i.p., once per day), also significantly antagonized cisplatin-induced acute and delayed emesis and was comparable with a once-daily regimen of ondansetron (1 mg/kg, p.o.) plus aprepitant (1 mg/kg, p.o.) in combination with dexamethasone (1 mg/kg, i.p.). Conclusion: In conclusion, netupitant has potent and long lasting anti-emetic activity against a number of emetic challenges indicating broad inhibitory properties. The convenience of protection afforded by the single dosing of netupitant together with palonosetron was demonstrated and also is known to provide an advantage over other therapeutic strategies to control emesis in man.

Abstract
To better understand the anti-emetic profile of the 5-HT3 (palonosetron)- and the tachykinin NK1 (netupitant) -receptor antagonists, either alone or in combination, we evaluated the effects of palonosetron and/or netupitant pretreatment on cisplatin-evoked vomiting and changes in the phosphorylation of brainstem kinases such as the extracellular signal-regulated protein kinases 1 and 2 (ERK1/2), protein kinase C alpha/beta (PKCα/β), and protein kinase A (PKA) in the least shrew. Our results demonstrate that cisplatin (10mg/kg, i.p.) causes emesis in the least shrew over 40h with respective peak early- and delayed-phases occurring at 1 - 2 and 32 - 34h post-injection. During the early phase (0 - 16h post cisplatin), palonosetron (0.1mg/kg, s.c.) significantly protected shrews from vomiting with a near complete suppression of vomit frequency. Palonosetron also significantly protected shrews from vomiting during the delayed phase (27 - 40h post cisplatin), but the reduction in mean vomit frequency failed to achieve significance. On the other hand, netupitant (5mg/kg, i.p.) totally abolished vomiting during the delayed phase, and tended to suppress the mean vomit frequency during the acute phase. The combined treatment protected shrews almost completely from vomiting during both phases. Brainstem pERK1/2 levels were significantly elevated at all time-points except at 40h post-cisplatin administration. PKA phosphorylation tended to be elevated throughout the delayed phase, but a significant increase only occurred at 33h. Brainstem pPKCα/β levels were enhanced during acute-phase with a significant elevation at 2h. Palonosetron, netupitant or their combination had no effect on elevated pERK1/2 levels during acute phase, but the combination reversed ERK1/2 phosphorylation at 33h post-cisplatin treatment. In addition, only the combined regimen prevented the cisplatin-induced PKCα/β phosphorylation observed at the acute phase. On the other hand, palonosetron and netupitant, either alone or in combination, were effective in reducing the induced elevated pPKA levels during the delayed phase. These effects on cisplatin-related emetic signals downstream of 5-HT3- and NK1-receptors help us to better understand the intracellular basis of cisplatin-induced vomiting.

Abstract
Gastrointestinal disorder is a common symptom induced by diverse pathophysiological conditions that include food tolerance, chemotherapy, and irradiation for therapy. Prostaglandin E2 (PGE2) level increase was often reported during gastrointestinal disorder and prostaglandin synthetase inhibitors has been used for ameliorate the symptoms. Exogenous administration of PGE2 induces gastrointestinal disorder, however, the mechanism of action is not known. Therefore, we tested PGE2 effect on visceral afferent sensory neurons of the rat. Interestingly, PGE2 itself did not evoked any response but enhanced serotonin (5-HT)-evoked currents up to 167% of the control level. The augmented 5-HT responses were completely inhibited by a 5-HT type 3 receptor antagonist, ondansetron. The PGE2-induced potentiation were blocked by a selective E-prostanoid type 4 (EP4) receptors antagonist, L-161,982, but type 1 and 2 receptor antagonist AH6809 has no effect. A membrane permeable protein kinase A (PKA) inhibitor, KT5720 also inhibited PGE2 effects. PGE2 induced 5-HT current augmentation was observed on 15% and 21% of the stomach and ileum projecting neurons, respectively. Current results suggest a synergistic signaling in visceral afferent neurons underlying gastrointestinal disorder involving PGE2 potentiation of 5-HT currents. Our findings may open a possibility for screen a new type drugs with lower side effects than currently using steroidal prostaglandin synthetase inhibitors by selectively targeting EP4 receptor/PKA pathway without interrupt prostaglandin synthesis.

Abstract
Nausea and vomiting are ubiquitous as drug side effects and symptoms of disease; however, the systems that determine these responses are arguably designed for protection against food poisoning occurring at the level of the gastrointestinal (GI) tract. This basic biological pathway using GI vagal afferent communication to the brain is not well understood. Part of this lack of insight appears to be related to current experimental approaches, such as the use of experimental drugs, including systemic chemotherapy and brain penetrant agents, which activate parts of the nausea and vomiting system in potentially unnatural ways. Directly related to this issue is our ability to understand the link between nausea and vomiting, which are sometimes argued to be completely separate processes, with nausea as an unmeasurable response in animal models. An argument is made that nausea and emesis are the efferent limbs of a unified sensory input from the GI tract that is likely to be impossible to understand without more specific animal electrophysiological experimentation of vagal afferent signaling. The current paper provides a review on the use of animal models and approaches to defining the biological systems for nausea and emesis and presents a potentially testable theory on how these systems work in combination.

Abstract
Low-dose dexamethasone has been widely used for the prevention of nausea and vomiting after chemotherapy and surgical procedures and to treat motion sickness due to its minimal adverse effects, but the mechanisms underlying its anti-motion sickness effects are poorly understood. Previous studies have demonstrated that the endocannabinoid system is suppressed by motion sickness but stimulated by dexamethasone. The aim of the present study was to determine whether dexamethasone has an anti-motion sickness effect in rats and to elucidate the mechanism of this action. We used HPLC-MS/MS to measure the plasma concentrations of anandamide and 2-arachidonoylglycerol+1-arachidonoylglycerol, and we employed real-time quantitative PCR (qRT-PCR) and/or Western blot analysis to assay the expression of N-acylphosphatidyl-ethanolamine hydrolyzing phospholipase D, sn-1-selective diacylglycerol lipase, fatty acid hydrolase, monoacylglycerol lipase and endocannabinoid CB1 receptor in the dorsal vagal complex and stomach of rats exposed to a motion sickness protocol. The results showed that dexamethasone lowered the motion sickness index and restored the levels of endogenous cannabinoids and the expression of the endocannabinoid CB1 receptor, which declined after the induction of motion sickness, in the dorsal vagal complex and stomach.

Abstract
BACKGROUND AND PURPOSE Emesis is a multi-system reflex, which is usually investigated using in vivo models. The aim of the study is to compare the response induced by emetic compounds across species and investigate whether dogs, ferrets and rats are all similarly predictive of humans. EXPERIMENTAL APPROACH A systematic review was carried out and relevant publications were identified from PubMed. The search was restricted to four species (human, dog, ferret, rat) and ten compounds representative of various mechanisms of emesis induction (apomorphine, cisplatin, cholecystokinin octapeptide, copper sulphate, cyclophosphamide, ipecacuanha, lithium chloride, morphine, nicotine, rolipram). KEY RESULTS 1046 publications were reviewed, and 311 were included, the main reason for exclusion was the lack of quantitative data. Emetic or pica data were extracted as incidence, intensity or latency. All three animal species identified emetic liability but interspecies differences for dose sensitivity were detected. CONCLUSIONS AND IMPLICATION These results suggest that emetic liability can be reliably identified in a common laboratory species such as the rat. However, to evaluate the characteristics of the emetic response, no animal species is a universal predictor of emetic liability and the choice of species should be an informed decision based on the type of compound investigated. Limitations relating to the conduct and reporting of emesis studies were identified, the main ones being the lack of comparable outcome measures between human and animal data, and the limited availability of human data in the public domain.

Abstract
BACKGROUND Prophylactic dexamethasone, ondansetron and droperidol have a documented effect on post-operative nausea and vomiting (PONV). Still, there is a lack of studies investigating the effect of adding dexamethasone to ondansetron and droperidol in order to treat established PONV. METHODS In this double-blind randomised, controlled trial, we compared triple prophylaxis for PONV consisting of dexamethasone 8 mg intravenous (IV), ondansetron 4 mg IV and droperidol 0.625 mg IV (n = 157) with placebo (n = 156) given before gynaecological day-case surgery. Subsequently, in those having PONV despite triple prophylaxis or placebo, a dose of ondansetron and droperidol plus dexamethasone was compared with the combination of ondansetron and droperidol. RESULTS Triple prophylaxis reduced acute PONV (0-6 h) (P = 0.0003) and post-discharge PONV (6-24 h) (P = 0.001) when compared with placebo. Among those suffering from PONV despite placebo or active prophylaxis (n = 80), adding dexamethasone to ondansetron and droperidol reduced acute PONV (0-6 h) (P = 0.025) as well as post-discharge nausea (6-24 h) (P = 0.04) compared with duo treatment comprising ondansetron and droperidol. In those reporting PONV despite prophylaxis (n = 12), the treatment comprising ondansetron and droperidol, with or without dexamethasone, gave a 91.7% reduction in acute PONV and an 83.6% reduction in post-discharge PONV. CONCLUSION Treatment of established PONV comprising ondansetron and droperidol, with or without dexamethasone, reduced PONV in both treatment groups. In those reporting PONV without active prophylaxis, the addition of dexamethasone resulted in a significant amplification of the PONV-reducing [corrected] effects of ondansetron and droperidol.

Abstract
Purpose The ferret cisplatin emesis model has been used for ~30 years and enabled identification of clinically used anti-emetics. We provide an objective assessment of this model including efficacy of 5-HT3 receptor antagonists to assess its translational validity. Methods A systematic review identified available evidence and was used to perform meta-analyses. Results Of 182 potentially relevant publications, 115 reported cisplatin-induced emesis in ferrets and 68 were included in the analysis. The majority (n = 53) used a 10 mg kg−1 dose to induce acute emesis, which peaked after 2 h. More recent studies (n = 11) also used 5 mg kg−1, which induced a biphasic response peaking at 12 h and 48 h. Overall, 5-HT3 receptor antagonists reduced cisplatin (5 mg kg−1) emesis by 68% (45–91%) during the acute phase (day 1) and by 67% (48–86%) and 53% (38–68%, all P < 0.001), during the delayed phase (days 2, 3). In an analysis focused on the acute phase, the efficacy of ondansetron was dependent on the dosage and observation period but not on the dose of cisplatin. Conclusion Our analysis enabled novel findings to be extracted from the literature including factors which may impact on the applicability of preclinical results to humans. It reveals that the efficacy of ondansetron is similar against low and high doses of cisplatin. Additionally, we showed that 5-HT3 receptor antagonists have a similar efficacy during acute and delayed emesis, which provides a novel insight into the pharmacology of delayed emesis in the ferret.

Abstract
Anticancer agents, such as cisplatin, stimulate nausea, vomiting, and behaviors indicative of malaise. Rats and mice do not possess a vomiting response, and, therefore, in these species, the ingestion of kaolin clay (a pica response) has been used as an index of malaise. In the rat, cisplatin-induced kaolin intake is inhibited by antiemetic treatments. In addition, cisplatin activates vagal afferent fibers in the gut, and kaolin intake induced by cisplatin is largely dependent on an intact vagus. Nevertheless, little is known about the brain pathways controlling pica. We investigated the role of the lateral parabrachial nucleus (lPBN), a major visceral afferent link between the hindbrain and forebrain, in cisplatin-induced c-Fos expression and pica. Injection of cisplatin (6 mg/kg ip) produced c-Fos expression in the ventrolateral (external) lPBN, a region receiving viscerosensory input. In rats with bilateral ibotenic acid lPBN lesions, cisplatin treatment substantially increased kaolin intake compared with controls ( approximately 30 g vs. approximately 5 g, respectively, over 24 h). Food intake was reduced by cisplatin treatment and by apomorphine, an emetic agent that acts centrally. Unlike cisplatin, however, apomorphine stimulated kaolin intake to a similar degree in both the lesioned and control rats, suggesting that lPBN damage neither produces nonspecific effects nor enhances malaise in general. These data suggest that lPBN-lesioned animals not only demonstrate pica after cisplatin treatment, but, in fact, show an exaggerated response that is greatly in excess of any treatment known to produce kaolin intake in rats.

Abstract
Cisplatin at 5 mg/kg, i.p. induced an acute (day 1) and delayed (days 2 and 3) emetic response in the ferret that was used to investigate the anti-emetic activity of the non-selective cyclooxygenase inhibitor indomethacin (3 - 30 mg/kg, i.p., three times per day) and two cyclooxygenase-2 inhibitors, DFU [5,5-dimethyl-3-(3-fluorophenyl)-4-(4-methylsulphonyl)phenyl-2(5H)-furanone; 1 - 10 mg/kg, i.p. administered at 40 and 48 h] and L-745,337 [5-methanesulphonamido-6-(2,4-diflurothiophenyl)-1-indanone; 10 mg/kg, i.p., administered at 40 and 48 h]. Only indomethacin potentiated significantly cisplatin-induced retching + vomiting (P<0.05); DFU antagonized delayed emesis (P<0.05) but the action was not dose-related and L-745,337 was inactive (P>0.05). However, indomethacin alone (30 mg/kg) also induced emesis (P<0.05). The leukotriene biosynthesis inhibitor, MK-886 {3-[1-(p-chlorobenzyl)-5-(isopropyl)-3-tert-butylthioindol-2-yl]-2,2-dimethylpropanoic acid; 1 - 10 mg/kg, i.p., three times per day} had no action to modify cisplatin-induced emesis (P>0.05). The combination treatment of indomethacin (10 mg/kg, i.p., three times per day) with MK-886 (10 mg/kg, i.p., three times per day) did not antagonize cisplatin-induced acute delayed retching + vomiting and had a different profile compared to the action of dexamethasone (1 mg/kg, i.p., three times per day; P<0.05). Inhibition of the cyclooxygenase and lipoxygenase pathways does not account for the anti-emetic of dexamethasone.

Abstract
PURPOSE The mechanism of the antiemetic actions of corticosteroids is not known. The purpose of this study was to evaluate if betamethasone can prevent nausea, vomiting or increase of vasopressin induced by apomorphine. Metoclopramide, a dopamine antagonist, was used as a control substance. METHODS Ten healthy volunteers were studied on three occasions. In a randomized order they were allocated to receive pretreatment with betamethasone 8 mg iv, metoclopramide 10 mg iv, and normal saline 2 mL as placebo on the three different occasions, 15 min before the administration of apomorphine 30 microg x kg(-1) s.c.. After administration of apomorphine, episodes of vomiting were recorded, and the intensity of nausea was estimated by the subject on a visual analogue scale (VAS 0-10 cm). Blood samples for analysis of plasma concentrations of vasopressin were analyzed. RESULTS One volunteer decided to withdraw, as he experienced akathisia after receiving metoclopramide. During the first two hours after apomorphine, eight of nine volunteers vomited both after betamethasone and placebo. One volunteer did not vomit after betamethasone and placebo but he experienced nausea. None of the volunteers vomited after metoclopramide (P < 0.01 vs betamethasone and placebo). The maximum VAS for nausea was significantly higher after betamethasone and placebo compared to metoclopramide (P < 0.01). The vasopressin levels increased after betamethasone and placebo, but there was no increase in any volunteer after pretreatment with metoclopramide. CONCLUSION This study demonstrates that betamethasone does not prevent nausea, vomiting and increase of vasopressin induced by apomorphine, whereas metoclopramide prevents apomorphine-induced emesis. Our work suggests that betamethasone does not have dopamine-antagonistic effects.

Abstract
Several prostanoids were investigated for a potential to induce emesis in Suncus murinus. The TP receptor agonist 11alpha,9alpha-epoxymethano-15S-hydroxyprosta-5Z,13E-dienoic acid (U46619) induced emesis at doses as low as 3 microg/kg, i.p. but the DP receptor agonist 5-(6-Carboxyhexyl)-1-(3-cyclohexyl-3-hydroxypropyl) hydantoin (BW245C) was approximately 1000 times less potent. The emetic action of U46619 (300 microg/kg, i.p.) was antagonized significantly by the TP receptor antagonist, vapiprost (P<0.05). EP (prostaglandin E(2), 17-phenyl-omega-trinor prostaglandin E(2), misoprostol and sulprostone), FP (prostaglandin F(2alpha) and fluprostenol) and IP (iloprost and cicaprost) receptor agonists failed to induce consistent emesis at doses up to 300-1000 microg/kg, i.p. Fluprostenol reduced nicotine (5 mg/kg, s.c.)-but not copper sulphate (120 mg/kg, intragastric)-induced emesis; the other inconsistently emetic prostanoids were inactive to modify drug-induced emesis. The results indicate an involvement of TP and possibly DP and FP receptors in the emetic reflex of S. murinus.

Abstract
Dexamethasone is an effective antiemetic drug, but its mechanism of action is unclear. We designed this study to investigate the direct antiemetic action of dexamethasone in the medulla of cats. By using an oscillographic vomiting model, decerebrated cats received microinjections of dexamethasone 100 nL (1 microg, n = 7; 0.1 microg, n = 7) into the bilateral nuclei tractus solitarii, which led to a significant prolongation of the latency (1 microg, 6.4 +/- 1.1 min versus 28.2 +/- 4.9 min, P < 0.05; 0.1 microg, 6.7 +/- 1.1 min versus 27.1 +/- 5.0 min, P < 0.05) of the first emetic episode and significantly decreased the frequency of emetic episodes (1 microg, 2.7 +/- 0.8 versus 0.1 +/- 0.4, P < 0.05; 0.1 microg, 2.9 +/- 0.9 versus 0.3 +/- 0.5, P < 0.05) induced by xylazine. Pretreatment with mifepristone, a glucocorticoid receptor antagonist, blocked the antiemetic effect of dexamethasone in the bilateral nuclei tractus solitarii. However, microinjection of dexamethasone into the unilateral nucleus tractus solitarius alone did not alter the latency of the first emetic episode or the frequency of emetic episodes induced by xylazine. Local application of dexamethasone into the area postrema had no effect on the latency of the first emetic episode or the frequency of emetic episodes induced by xylazine. These results suggest that dexamethasone exerts its central antiemetic action through an activation of the glucocorticoid receptors in the bilateral nuclei tractus solitarii in the medulla.

Abstract
The emetic action of the prostanoid TP receptor agonist, 11alpha,9alpha-epoxymethano-15S-hydroxyprosta-5Z,13E-dienoic acid (U46619; 300 microg/kg, i.p.), was investigated in Suncus murinus. The emetic response was reduced by 76% following bilateral abdominal vagotomy (P<0.001) and by reserpine (5 mg/kg, i.p., 24 h pretreatment; P<0.05) but U46619 administered i.c.v. (30-300 ng) was not emetic, suggesting a peripheral mechanism involving monoamines. However, fenfluramine (5 mg/kg, repeated treatment) and para-chlorophenylalanine (100-400 mg/kg) and ondansetron (0.3-3 mg/kg) were inactive (P>0.05) to reduce U46619-induced emesis precluding a role of 5-HT and 5-HT(3) receptors in the mechanism. Similarly, phentolamine (0.3-3 mg/kg), propranolol (3 mg/kg), and their combination, and metoclopramide (0.3-3 mg/kg), domperidone (0.3-3 mg/kg), droperidol (0.3-3 mg/kg), scopolamine (0.3-3 mg/kg) and promethazine (0.3-3 mg/kg) were inactive (P>0.05) to reduce the retching and vomiting response. However, the tachykinin NK(1) receptor antagonist, (+)-2S,3S(-3-(2-methoxy-5-trifluoromethoxybenzyl)amino-2-phenylpiperidine) (CP-122,721; 1-10 mg/kg) antagonized emesis (P<0.01). In conclusion, U46619-induced emesis appears to be mediated via a predominant peripheral mechanism sensitive to reserpine and is not likely to involve adrenoceptors, dopamine, 5-HT(3), muscarinic or histamine (H(1)) receptors. The action of CP-122,721 to reduce U46619-induced emesis extends the spectrum of anti-emetic action tachykinin NK(1) receptor antagonists to mechanisms involving TP receptors.

Abstract
We investigated the ability of dexamethasone to attenuate cisplatin (4 mg/kg, i.v.)-induced early and delayed emesis. These appear within the first 8-h period (early phase) and between 8 and 48 h (delayed phase), respectively, after cisplatin administration in the pigeon. Dexamethasone (0.1 and 1 mg/kg, i.m.) reduced significantly the number of emetic responses to cisplatin by 56% and 82% (P<0.05), respectively, in the early phase, and by 41% and 66% (P<0.05), respectively, in the delayed phase. Dexamethasone (1 and 10 microg/kg, i.c.v.) reduced the number of emetic responses by 66% and 91% (P<0.05), respectively, in the early phase, and by 56% and 87% (P<0.05), respectively, in the delayed phase. Indomethacin (10 mg/kg, i.m.) did not suppress cisplatin-induced early and delayed emesis. Dexamethasone (1 mg/kg, i.m.) did not affect the content of platinum in the medulla oblongata after cisplatin administration. The above results suggest that dexamethasone has antiemetic effects on both the early and delayed emetic responses to cisplatin in pigeons, partially via its central site of action, and that the antiemetic mechanism of dexamethasone is related to factors other than its inhibition of prostanoid synthesis or its membrane stabilizing effect which reduces influx of cisplatin into the medulla oblongata.

Abstract
Ondansetron (1-3 mg/kg), granisetron (0.3-1 mg/kg) and dexamethasone (0.3-1 mg/kg), administered at 12-h intervals, were investigated for their potential to prevent cisplatin (30 mg/kg, i.p.)-induced emesis during a 72-h observation period. Ondansetron appeared more active than granisetron to antagonise the emetic response occurring in the first 4-h (P<0.05) period, but none of the regimens significantly antagonised emesis during the 0-24- and 24-72-h periods (P>0.05). However, ondansetron was more active to antagonise emesis on day 1 using a more frequent drug administration, whereas bilateral vagotomy only reduced emesis for 2 h, and 5-HT, 2-methyl-5-HT and 1-m-chloro-phenylbiguanide (up to 20-30 mg/kg, i.p.) were not emetic. The combination of ondansetron 1 mg/kg and dexamethasone 1 mg/kg, both administered every 12 h, significantly delayed the onset of emesis (P<0.05) but failed to reduce the total numbers of retches+vomits over the 3-day period (P>0.05). Results are discussed in relation to the clinical situation.

Abstract
Cisplatin 5 mg/kg, i.p., induced an acute (day 1) and delayed (days 2 and 3) emetic response in the ferret that was used to investigate the potential anti-emetic activity of metyrapone and tetracosactrin and their potential interaction. The 11beta-hydroxylase enzymes inhibitor metyrapone 10-30 mg/kg, i.p., dose dependently potentiated the acute cisplatin-induce retching+vomiting response by up to 219% at the highest dose (P<0.001) but failed to affect significantly delayed emesis (P>0.05). The adrenocorticotropic hormone (ACTH) mimetic tetracosactrin 0.1 mg/kg, i.m., antagonised significantly the acute and delayed emetic response by 98% (P<0.01) and 75% (P<0.001), respectively. The anti-emetic action of tetracosactrin on acute but not delayed emesis was prevented by combination with metyrapone 10 mg/kg, i.p. Tetracosactrin 0.1 mg/kg, i.m., failed to modify apomorphine (0.25 mg/kg, s.c.)-induced emesis. The potential anti-emetic mechanism of action of metyrapone and tetracosactrin to modulate emesis is discussed.

Abstract
The ability of cisplatin to induce acute (0-24 h) and delayed (24-48 and 48-72 h) phases of kaolin ingestion (pica) was investigated in the rat. Cisplatin 3 mg/kg, i.p., induced kaolin consumption during the 0-24- (P<0.001) and 48-72-h (P<0.05) periods that was antagonised by dexamethasone 1 mg/kg, i.p., administered every 12 h alone or in combination with ondansetron 2 mg/kg, i.p., administered every 12 h (P<0.05). As a single treatment, ondansetron 2 mg/kg, i.p., administered every 12 h potentiated cisplatin-induced kaolin consumption by 41% (P<0.05) during the 0-24-h period but had no action to modify the delayed response (P>0.05). Dexamethasone 1 mg/kg, i.p., administered every 12 h and cisplatin 3 and 6 mg/kg, i.p., but not ondansetron 2 mg/kg, i.p., administered every 12 h (P>0.05) reduced food consumption and decreased rat weight. The highest dose of cisplatin 6 mg/kg, i.p., induced acute (P<0.001) but not delayed kaolin ingestion (P>0.05). The action of cisplatin to induce acute and delayed pica is complicated and may be affected by drugs that modify appetite.

Abstract
We analysed the effects of four cyclooxygenases (COX) inhibitors on cisplatin-induced emesis in piglets. Ninety-five animals receiving cisplatin (5.5 mg kg(-1), i.v.) were observed for 60 h. One hour prior to cisplatin, controls (n=29) were dosed with a saline solution while experimental animals received an i.v. or i.p. injection of one of the COX inhibitors. Additional injections of COX inhibitor were given at 15 and 39 h after cisplatin administration (or every 6h in one group receiving diclofenac). The latencies to the first emetic episode (EE) compared to controls (2.1+/-0.4 h) increased in groups receiving naproxen (4.66+/-0.94 h, n=9, 30 mg kg(-1)) and indomethacin (6.19+/-1.13 h, n=7, 10 mg kg(-1)) i.v. Indomethacin significantly decreased the incidence of both the acute (by 40%) and delayed (by 66%) phases of emesis. The total number of EE during the 60 h compared to controls (28.3+/-1.9 EE) was significantly reduced in piglets receiving indomethacin (14.9+/-3.2 EE, n=7) and meloxicam (17.6+/-3.6 EE, n=11, 0.3 mg kg(-1)). Four piglets receiving meloxicam (0.3 mg kg(-1), i.v.) did not vomit during the delayed phase. The anti-emetic activity of two COX inhibitors suggests that prostaglandins contribute to the activation of the emetic reflex in response to cisplatin.
