Plasma Polyamines and Short-Term Adverse Outcomes Among Patients With Ischemic Stroke: A Prospective Cohort Study. J Am Heart Assoc 2024; 13:e035837. [PMID: 39082415 DOI: 10.1161/jaha.124.035837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Accepted: 07/01/2024] [Indexed: 08/07/2024]
Abstract
BACKGROUND Polyamines have been reported to be associated with neurological function, but the associations between polyamines and the prognosis of ischemic stroke remain unclear. We aimed to prospectively investigate whether elevated plasma polyamine levels are associated with adverse outcomes in patients with ischemic stroke. METHODS AND RESULTS Plasma polyamine levels were measured at admission in 3570 patients with acute ischemic stroke, and clinical outcomes were assessed at 3 months after stroke onset. The primary outcome was a composite outcome of death and major disability (modified Rankin Scale score≥3), and secondary outcomes included the individual outcomes of death and major disability. During a 3-month follow-up period, 877 participants (25.1%) experienced the primary outcome. Increased putrescines were associated with a decreased risk of the primary outcome (the highest versus the lowest tertile: odds ratio, 0.72 [95% CI, 0.58-0.91]; P=0.005) and major disability (odds ratio, 0.59 [95% CI, 0.47-0.74]; P<0.001). Conversely, increased spermidines were associated with an increased risk of death (hazard ratio, 1.86 [95% CI, 1.10-3.14]; P=0.020), and increased spermines were associated with an increased risk of the primary outcome (odds ratio, 1.36 [95% CI, 1.08-1.71]; P=0.009) and major disability (odds ratio, 1.27 [95% CI, 1.01-1.59]; P=0.041). CONCLUSIONS Among patients with ischemic stroke, high plasma putrescine levels were associated with a decreased risk of adverse outcomes, whereas high plasma spermidine and spermine levels were associated with an increased risk of adverse outcomes. Further studies are needed to investigate whether targeting these polyamines can improve the prognosis of patients with ischemic stroke. REGISTRATION https://clinicaltrials.gov.

RSC Adv 2019; 9:19584-19595.

Abstract
Weaning stress can cause metabolic disorders, gastrointestinal dysfunction, physical barrier injury and disease susceptibility, thus leading to impaired growth and health of animals. Putrescine has the potential to reduce stress effects. However, the role of putrescine supplementation on barrier function and antioxidant capacity in animals' organs is largely unknown. This study evaluates the effects of putrescine on the physical barrier function, antioxidant status and related signalling molecule levels of weaning piglets' organs. A total of 24 weaning piglets were assigned to four treatment groups: (1) basal diet (control) and basal diets supplemented with (2) 0.05%, (3) 0.1% and (4) 0.15% putrescine. At the end of the 11 day experiment, ileum, liver, thymus and spleen samples were collected from the piglets. Compared with the control group, 0.15% putrescine can significantly increase anti-hydroxyl radical capacity (ileum and spleen), anti-superoxide anion capacity (liver, thymus and spleen), catalase (ileum, liver, thymus and spleen), total superoxide dismutase (ileum, thymus and spleen), glutathione peroxidase (ileum, liver and thymus), glutathione S-transferase activity (ileum, liver, thymus and spleen), glutathione content (liver and spleen) and total antioxidant capacity (ileum and thymus); decrease malondialdehyde (ileum, liver, thymus and spleen), protein carbonyl content (ileum, liver, thymus and spleen); enhance mRNA expression of zonula occludens (ZO)-1 (spleen), ZO-2 (liver, thymus and spleen), occludin (ileum, liver, thymus and spleen), claudin 1 (ileum, liver, thymus and spleen), claudin 2 (ileum, thymus and spleen), claudin 3 (ileum, liver, thymus and spleen), claudin 14 (ileum, liver and spleen), claudin 16 (ileum and liver), superoxide dismutase 1 (ileum, liver and thymus), glutathione peroxidase 1 (ileum, liver, thymus and spleen), catalase (ileum, liver, thymus and spleen), glutathione reductase (thymus and spleen), glutathione S-transferase (ileum, liver, thymus and spleen) and nuclear erythroid 2-related factor 2 (liver and thymus); decrease mRNA level of myosin light chain kinase (ileum, liver, thymus and spleen) and Kelch-like ECH-associated protein 1 (liver and spleen) (P < 0.05). 0.05% putrescine can significantly affect some of the above-mentioned parameters (P < 0.05). Collectively, putrescine supplementation improves organs' physical barrier function and antioxidant capacity in dose- and tissue-dependent and independent effects; such improvements are beneficial to the health of weaning piglets. Weaning stress can cause metabolic disorders, gastrointestinal dysfunction, physical barrier injury and disease susceptibility, thus leading to impaired growth and health of animals.![]()

Roux-en-Y gastric bypass surgery of morbidly obese patients induces swift and persistent changes of the individual gut microbiota. Genome Med 2016; 8:67.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is an effective means to achieve sustained weight loss for morbidly obese individuals. Besides rapid weight reduction, patients achieve major improvements of insulin sensitivity and glucose homeostasis. Dysbiosis of gut microbiota has been associated with obesity and some of its co-morbidities, like type 2 diabetes, and major changes of gut microbial communities have been hypothesized to mediate part of the beneficial metabolic effects observed after RYGB. Here we describe changes in gut microbial taxonomic composition and functional potential following RYGB. METHODS We recruited 13 morbidly obese patients who underwent RYGB, carefully phenotyped them, and had their gut microbiomes quantified before (n = 13) and 3 months (n = 12) and 12 months (n = 8) after RYGB. Following shotgun metagenomic sequencing of the fecal microbial DNA purified from stools, we characterized the gut microbial composition at species and gene levels followed by functional annotation. RESULTS In parallel with the weight loss and metabolic improvements, gut microbial diversity increased within the first 3 months after RYGB and remained high 1 year later. RYGB led to altered relative abundances of 31 species (P < 0.05, q < 0.15) within the first 3 months, including those of Escherichia coli, Klebsiella pneumoniae, Veillonella spp., Streptococcus spp., Alistipes spp., and Akkermansia muciniphila. Sixteen of these species maintained their altered relative abundances during the following 9 months. Interestingly, Faecalibacterium prausnitzii was the only species that decreased in relative abundance. Fifty-three microbial functional modules increased their relative abundance between baseline and 3 months (P < 0.05, q < 0.17). These functional changes included increased potential (i) to assimilate multiple energy sources using transporters and phosphotransferase systems, (ii) to use aerobic respiration, (iii) to shift from protein degradation to putrefaction, and (iv) to use amino acids and fatty acids as energy sources. CONCLUSIONS Within 3 months after morbidly obese individuals had undergone RYGB, their gut microbiota featured an increased diversity, an altered composition, an increased potential for oxygen tolerance, and an increased potential for microbial utilization of macro- and micro-nutrients. These changes were maintained for the first year post-RYGB. TRIAL REGISTRATION Current controlled trials (ID NCT00810823 , NCT01579981 , and NCT01993511 ).

Abstract
Bariatric surgery, also known as metabolic surgery, is an effective treatment for morbid obesity, which also offers pronounced metabolic effects including the resolution of type 2 diabetes and a decrease in cardiovascular disease and long-term cancer risk. However, the mechanisms of surgical weight loss and the long-term consequences of bariatric surgery remain unclear. Bariatric surgery has been demonstrated to alter the composition of both the microbiome and the metabolic phenotype. We observed a marked shift toward Gammaproteobacteria, particularly Enterobacter hormaechei, following Roux-en-Y gastric bypass (RYGB) surgery in a rat model compared with sham-operated controls. Fecal water from RYGB surgery rats was highly cytotoxic to rodent cells (mouse lymphoma cell line). In contrast, fecal water from sham-operated animals showed no/very low cytotoxicity. This shift in the gross structure of the microbiome correlated with greatly increased cytotoxicity. Urinary phenylacetylglycine and indoxyl sulfate and fecal gamma-aminobutyric acid, putrescine, tyramine, and uracil were found to be inversely correlated with cell survival rate. This profound co-dependent response of mammalian and microbial metabolism to RYGB surgery and the impact on the cytotoxicity of the gut luminal environment suggests that RYGB exerts local and global metabolic effects which may have an influence on long-term cancer risk and cytotoxic load.

Abstract
The natural polyamines putrescine, cadaverine, spermidine, and spermine are found in all cells. These (poly)cations exert interactions with anions, e.g., DNA and RNA. This feature represents their best-known direct physiological role in cellular functions: cell growth, division, and differentiation. The lung and, more specifically, alveolar epithelial cells appear to be endowed with a much higher polyamine uptake system than any other major organ. In the lung, the active accumulation of natural polyamines in the epithelium has been studied in various mammalian species including rat, hamster, rabbit, and human. The kinetic parameters (Michaelis-Menten constant and maximal uptake) of the uptake system are the same order of magnitude regardless of the polyamine or species studied and the in vitro system used. Also, other pulmonary cells accumulate polyamines but never to the same extent as the epithelium. Although different uptake systems exist for putrescine, spermidine, and spermine in the lung, neither the nature of the carrier protein nor the reason for its existence is known. Some pulmonary toxicological and/or pathological conditions have been related to polyamine metabolism and/or polyamine content in the lung. Polyamines possess an important intrinsic toxicity. From in vitro studies with nonpulmonary cells, it has been shown that spermidine and spermine can be metabolized to hydrogen peroxide, ammonium, and acrolein, which can all cause cellular toxicity. In hyperoxia or after ozone exposure, the increased polyamine synthesis and polyamine content of the rat lung is correlated with survival of the animals. Pulmonary hypertension induced by monocrotaline or hypoxia has also been linked to the increased polyamine metabolism and polyamine content of the lung. In a small number of studies, it has been shown that polyamines can contribute to the suppression of immunologic reactions in the lung.

Abstract
Mast cells release many biologically active molecules upon stimulation by a variety of molecules such as immunoglobulin E (IgE) and specific antigen, anaphylatoxins, as well as a number of cationic compounds which include drugs, kinins and neuropeptides. The effect of the naturally occurring polyamine spermine was studied because, even though it is polycationic, it has been implicated in the modulation of secretory processes in a variety of cells. In particular, it was previously shown that oxidation products of spermine inhibit mast cell secretion. High concentrations of spermine (5 x 10(-3) M) added at 37 degrees C induced mast cell secretion that had similar characteristics with that triggered by compound 48/80 (48/80). However, spermine inhibited mast cell secretion in a dose-dependent manner as long as it was added at 4-10 degrees C for at least 10 min in the absence of Ca++ before warming the cells to 37 degrees C and triggering them with 48/80. These findings were true both for purified rat peritoneal mast cells and for rat skin mast cells in situ. Addition of calcium after the cells had been warmed to 37 degrees C could not reverse this inhibition. The inhibition seen when spermine was added at 4 degrees C was, however, overcome if phorbol myristate acetate (PMA) or NaF, which activate PKC and G proteins respectively, were added to mast cells at 37 degrees C together with Ca++. These results indicate that polyamines could be important modulators of the activation state of mast cells and might help further define the biochemical events involved in mast cell secretion.

Abstract
Nine 3-(2-aminoethyl)pyrrole derivatives were investigated as anti-inflammatory agents in the carrageenan-induced rat paw oedema model and as antioxidants in the non-enzymatic lipid peroxidation assay. It was found that the derivatives which were substituted with a p-toluenesulphonyl group exhibited considerable anti-inflammatory activity and some also showed antioxidant properties. However, the presence of a p-toluenesulphonyl group did not invariably lead to activity. A structural feature which was essential for both activities was the aminoethyl side chain. Although a relationship between the antiinflammatory and the antioxidant activities was not apparent, the combination of these properties could be useful.

Abstract
Hepatic polyamines were assayed in 15 patients with liver diseases, 5 with fulminant hepatitis (FH); 3 with exacerbated liver cirrhosis (ELC); and 7 with liver cirrhosis (LC). Hepatic putrescine and N1-acetylspermidine as percentages of total polyamines, were elevated and spermine was decreased in all 15 patients. The increase in hepatic N1-acetylspermidine levels appeared to be greater in patients with FH and ELC than in those with LC. These results suggest that the production of N1-acetylspermidine in human liver is closely associated with the induction of spermidine/spermine N1-acetyltransferase activity in liver diseases.

Abstract
The polyamines putrescine, spermidine and spermine are essential for normal cell function and proposed to be involved in inflammatory reactions. The polyamines were measured bilaterally in rabbit aqueous humor after unilateral endotoxin-induced uveitis. The contralateral eyes were injected with saline or not touched. Aqueous protein levels and leukocytes were determined and a histological evaluation was performed. Protein, leukocytes, putrescine and spermine increased in the treated eyes, but not in the untouched eyes. When saline was injected in the contralateral eye, a small increase in spermine was seen. Spermidine decreased first, but increased later, in both the endotoxin-injected and the other eye. Histopathologically, the treated eyes showed an infiltration of leukocytes, vasodilatation and in some cases optic nerve involvements. A mild reaction was also seen in the unchallenged contralateral eyes. The results show that polyamines might serve as a marker for acute inflammation in the eye and that the mechanism of putrescine and spermine induction is different from the one of spermidine. Polyamines are suggested to play a role in the cellular immune response.

Abstract
In an attempt to elucidate the effects of estrogen on polyamine metabolism in lipopolysaccharide (LPS)-treated mice, we assayed polyamine content and the activity of spermidine/spermine N1-acetyltransferase (SAT) and ornithine decarboxylase (ODC) in some organs. LPS elevated N1-acetylspermidine levels in the liver and lung and putrescine levels in the liver, lung and spleen. LPS increased the activity of ODC at 6 h and that of SAT at 12 h in the liver. When estradiol-17 beta was simultaneously administered with LPS, the maximum increase in hepatic N1-acetylspermidine levels was found 6 h earlier than in the LPS control. Likewise, the peak of the hepatic SAT activity after LPS-treatment was observed 6 h earlier in the estradiol-17 beta-treated mice than in the LPS control. No such effect of estradiol-17 beta was found in the lung and spleen. The LPS-induced ODC activity was not affected by estradiol-17 beta in the liver, lung or spleen. Estrone and 16 beta-ethylestradiol (an anti-estrogen) were also effective in enhancing the LPS-induced elevation of N1-acetyl-spermidine and putrescine in the liver, while both diethylstilbestrol, which has a potent estrogenic activity without steroid structure and estradiol-17 alpha (a non-estrogenic isomer of estradiol-17 beta) were without effect. Tamoxifen (an estrogen receptor antagonist) did not suppress the estrogen-induced increase in hepatic N1-acetylspermidine levels.

Abstract
Mast cells secrete many biologically active compounds upon stimulation by immunoglobulin E (IgE) and specific antigen (Ag), anaphylatoxins, as well as a number of cationic compounds which include drugs, kinins and neuropeptides. The effects of the two naturally occurring polyamines, spermine (SP) and spermidine (SPD), on mast cell secretion were studied because they have been implicated in the modulation of cellular processes, possibly through their cationic charge or the regulation of calcium ions. SP and SPD over the range of 10(-7) to 10(-4) M inhibited the release of 5-hydroxytryptamine (5-HT, serotonin) triggered by compound 48/80 (C48/80) in a time- and concentration-dependent manner, as long as at least 2% calf serum (CS) was present. SP also inhibited secretion of both histamine and serotonin stimulated immunologically by using IgE and anti-rat IgE. This inhibition was not accompanied by cytotoxicity. The major available polyamine metabolites tested, N1-acetyl spermine (N1-acSP) and N8-acetyl spermidine (N8-acSPD), also showed inhibition in the presence of CS, whereas putrescine, N8,N1-hexamethylene-bis-acetamide (HMBA) and benzylamine did not. Fetal bovine serum (FBS), as well as human and rat serum, which do not contain polyamine oxidase, did not result in any inhibition with the polyamines tested. Inhibitors of the polyamine oxidase blocked the polyamine effect, indicating that the inhibition of mast cell secretion must derive from aldehydes produced from these polyamines. Addition of the aldehyde inhibitor phenylhydrazine (phi-HDZ), simultaneously with, but not following the polyamines, blocked their inhibitory effect, further strengthening the involvement of aldehydes. These results indicate that naturally occurring polyamines may regulate mast cell secretion through metabolic products of polyamine oxidase, a similar enzyme of which is also present in human liver, placenta and pregnant serum.

Abstract
The polyamines putrescine, spermidine and spermine are necessary for cellular growth and directly involved in cellular differentiation and cell death. The hypothesis that extracellular polyamine levels in rabbit aqueous humor could be used as biomarkers for trauma after eye surgery was investigated. Changes in polyamine levels in rabbit aqueous humor were measured after anterior chamber lens implantation and compared to normals. The measurements were made by reversed phase HPLC and 9-fluorenylmethyl chloroformate and fluorescence detection. An increase in protein concentration followed by a white blood cell mobilization in the aqueous humor is a response to trauma to the eye. Therefore, the polyamine levels were compared to the aqueous levels of protein and leukocytes. Three days postoperatively a significant increase in spermidine was observed and a significant correlation between elevated protein levels and elevated spermine as well as total polyamines were noticed. No correlation between a high number of leukocytes and high polyamine levels were found. The results suggest that polyamines are evident markers for surgical trauma response, but not necessarily correlated to the postoperative inflammatory phase and the infiltration of inflammatory cells.

Abstract
We examined the effects of low-level ozone (O3) inhalation on polyamine metabolism and tritiated thymidine (3H-TdR) incorporation into DNA in rat lungs. We have also compared the activities of ornithine decarboxylase (ODC), the rate-limiting enzyme of polyamine biosynthesis, and glucose-6-phosphate dehydrogenase (G6PD), the key enzyme of the pentose phosphate cycle and a typical marker of oxidant injury, to assess whether ODC can serve as a sensitive marker of O3 effects on the lung. We exposed 90-day-old male specific-pathogen-free Sprague-Dawley rats to either 0.45 +/- 0.05 ppm (882 +/- 98 micrograms/m3) O3 or filtered room air continuously for 3 days. After exposure, the rats were terminated and the lungs examined for enzyme activities, polyamine contents, DNA content, and 3H-TdR incorporation. We found that in exposed rats, the enzyme activities were significantly increased (p less than 0.05) relative to air controls. G6PD, 25%, ODC, 147%, and S-adenosylmethionine decarboxylase (AdoMet DC), 86%. Polyamine contents were also affected by O3; putrescine increased 80%, p less than 0.05, spermidine did not change, and spermine decreased 23%, p less than 0.05. 3H-TdR incorporation into DNA was significantly elevated, 155%, p less than 0.001, after O3 exposure while total lung DNA content remained unchanged. The concomitant and large increase in ODC activity (reflecting polyamine metabolism) and DNA labeling (reflecting DNA synthesis and/or repair), indicates a strong correlation between the two and suggests that polyamine metabolism may play an important role in the accelerated cell proliferation associated with O3 injury. Moreover, the greater increase in lung ODC activity compared to other enzymes offers a sensitive marker of the lung response to inhaled O3. We conclude that inhalation of O3 at levels similar to what may be encountered during some smog episodes can result in significant pulmonary biochemical alterations with a potential for long-term consequences. The possible association between ODC activity and DNA labeling may offer a new insight into the mechanism of tissue injury and repair. We also speculate that the changes in lung polyamines may reflect antioxidant and anti-inflammatory functions associated with the cellular defense against oxidant injury.

Abstract
The effect of turpentine, a chemical inflammatory agent, on polyamine synthesis has been studied. Ornithine decarboxylase activity is markedly increased in liver 6 hrs after subcutaneous injection of turpentine, and then decreases. No significant modification is observed in S-adenosylmethionine decarboxylase. Putrescine injected prior to turpentine prevents this increase. Putrescine, spermidine and spermine concentrations are all increased following turpentine, but with different patterns: spermidine alone keeps increasing for 50 hours. Putrescine and spermidine injected prior to turpentine partially counteract the increase of serum alpha 2-macroglobulin, which is believed to be a marker of inflammation.

Abstract
Active oxygen species produced by the action of xanthine oxidase or stimulated guinea-pig polymorphonuclear leucocytes have a lytic action of lysosomes possibly due to lipid peroxidation. Polyamines give some protection against lysis with putrescine being the most effective polyamine. The possible relevance to inflammatory disease is discussed.

Abstract
A non-controlled clinical phase IV trial was carried out involving 20,641 patients with osteoarthritis of the knee, the hip, and the spine and also with osteoarthritic polyarthritis of the fingers, who were treated with ademetionine tablets given in a fixed dosage schedule for eight weeks. No additional analgesic/antirheumatic treatment was allowed. Nevertheless, concomitant medication for other diseases was permissible. The efficacy was described as "very good" or "good" in 71 percent of cases, as "moderate" in 21 percent, and as "poor" in 9 percent of cases. The tolerance was assessed as very good or good in 87 percent, as moderate in 8 percent, and as poor in 5 percent of cases. The trial therapy was discontinued prematurely because of symptoms of intolerance in 5 percent of the patients and because of a lack of efficacy in 2.3 percent of cases.

Abstract
Endogenous polyamines with anti-inflammatory activity scavenge superoxide and possibly other oxy-radicals produced by xanthine oxidase or from stimulated polymorphonuclear leucocytes. Polyamines incubated with stimulated cells are in part metabolised. Putrescine is converted to metabolites tentatively identified as gamma-aminobutyraldehyde, delta'-pyrolline and gamma-aminobutyric acid. The metabolism of spermidine, spermine and cadaverine was not as extensively studied but metabolites were formed that gave positive reaction to Schiffs reagent on tlc plates. The possible relevance of the results to the anti-inflammatory action of polyamines is discussed.

Abstract
Intraperitoneal injection of putrescine induced dose-related hypothermia in rats. The effect was more pronounced at room temperature (22 degrees C) than in a warm environment (30 degrees C), the maximum hypothermia (-2.64 +/- 0.29 degrees C, 30 min. after treatment) being obtained with the dose of 300 mg/Kg and remaining significant throughout 3 hr of observation. Putrescine also had antipyretic activity, as it significantly reduced pyrogen-induced fever at a dose level (100 mg/Kg i.p.) ineffective in causing hypothermia in normal rats. The hypothermic and antipyretic effects of putrescine were not associated with any obvious sign of toxicity.

Abstract
The addition of the polyamines, spermine and spermidine, to human neutrophils caused a depression of the hexose-monophosphate (HMP) shunt activity of neutrophils stimulated with latex particles but not of unstimulated cells. The effect was dependent on the presence of bovine serum and was not observed when normal human serum was substituted for bovine serum. The polyamine oxidase (PAO) in bovine serum was probably responsible for generating the activity since normal human serum lacks PAO. A role for PAO was further supported by the finding that partially purified bovine PAO in the presence of polyamines similarly mediated inhibition of HMP shunt activity in stimulated neutrophils. Catalase failed to prevent the inhibitory effects of the PAO-polyamine system suggesting that H2O2 is not the responsible product. In addition, our results show that human pregnancy serum known to contain PAO activity in the presence of polyamines mediated a similar inhibition of the respiratory burst.

Abstract
Endogenous concentrations of putrescine, spermidine, spermine and related biosynthetic enzymes were not affected by the administration of bacterial endotoxin and the subsequent development of fever in rabbits. In addition, the febrile response to endotoxin was unaffected either by the ornithine decarboxylase inhibitor, DL-alpha-difluoromethylornithine or by putrescine. These data indicate polyamines are not involved in the development of fever.

Abstract
Increased plasma protein leakage induced by i.d. injections of histamine, 5-hydroxytryptamine, bradykinin, prostaglandin E2 and ionophore A23187 in the rat skin was inhibited non-specifically by enprofylline and aminophylline in a dose related manner. Depending on the agonist used, on a weight basis enprofylline was 2.9-6.6 times more potent than aminophylline when both were given i.p. and 1.4-2.2 times more active when administered orally. Inhibitory actions of enprofylline and aminophylline were unaffected by pretreatment of animals with phentolamine and propranolol, but reduced in adrenalectomized animals.

Abstract
The influence of counter irritation by turpentine on carrageenan-oedema, leucocyte count, plasma kininogen stores and composition of sponge-induced exudates has been investigated in the rat. Counter irritation reduced the carrageenan-oedema in normal as well as in adrenalectomized rats. It induced leucopenia with lymphopenia but did not modify the plasma kininogen stores. In turpentine-pretreated rats, the exudates induced by sponge implantation 18 h previously had a lower content in leucocytes. Their levels in beta-glucuronidase and beta-galactosidase were slightly reduced, their content in PGE2 was not modified and their level in malonaldehyde was increased. The exudates induced by sponge implantation 4 h previously had a lower content in leucocytes and PGE2 while their level in kinins was not modified. The mechanism of the anti-inflammatory effect of counter irritation by turpentine is discussed. We suggest that the main factor involved is a decrease in leucocyte accumulation into the exudates.
