RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Prinsepiautilis (PU) Royle, native to the Himalayan region, is a deciduous thorny shrub with numerous traditional uses of its roots, leaves and seeds for treatment of conditions such as rheumatic pain, joint pain, arthritis, and inflammation. AIM OF THE STUDY: Keeping in mind the growing demand of products of natural origin as alternate medicine, the present study was undertaken to scientifically validate for the first time the traditional claims of healing pain and inflammation by evaluating the fatty oil isolated from the seeds using established in vitro and in vivo models. MATERIALS AND METHODS: PU Seeds were Soxhlet extracted using n-hexane and fatty oil was isolated. Chemical composition of the oil was established with the aid of Gas Chromatography-Flame Ionization Detection (GC-FID) and Gas Chromatography-Mass Spectrometry (GC-MS). The oil was then subjected to in vitro anti-inflammatory activity by following the established protocols of trypsin inhibitory and bovine serum albumin denaturation assays. The acute toxicity of the oil was also studied using OECD guidelines 423. The anti-inflammatory property of the oil was further evaluated using carrageenan-induced and formalin-induced edema in the rat paw. Moreover, hot plate latency and tail immersion assay were employed to evaluate analgesic activity of the oil. To establish the quality of the oil, various physicochemical properties were also studied. RESULTS: GC-FID and GC-MS analysis of the oil revealed the presence of linoleic acid (59.06 ± 0.00%), oleic acid (28.11 ± 0.01%), palmitic acid (9.51 ± 0.01%) and stearic acid (3.32 ± 0.01%). In vitro trypsin inhibitory and bovine serum albumin denaturation assay revealed dose-dependent notable activity of the oil with IC50 value of 63.57 µg/mL and 518.14 µg/mL, respectively. The physico-chemical characterization demonstrated that the oil possesses a low acidity and a high oxidative stability index. The oil was found to be non-toxic and displayed effective anti-inflammatory activities with significant inhibition till 4 h in carrageenan-induced and formalin-induced rat paw edema at maximum tested dose of 200 mg/kg b.w. The oil also exhibited significant results in hot plate latency and tail immersion assay with positive effects showing up to 4 h after dose administration. CONCLUSION: These findings, besides supporting the traditional claims, suggest that P. utilis seed oil has potential therapeutic applications as a natural anti-inflammatory and analgesic agent. Further studies are warranted to explore its mechanisms of action and potential use in pharmaceutical and nutraceutical industries.

RESUMO

Objective: With the number of patients with acute pancreatitis (AP) increasing year by year, it is pressing to explore new key genes and markers for the treatment of AP. miR-455-3p/solute carrier family 2 member 1 (Slc2a1) obtained through bioinformatics analysis may participate in the progression of AP. Materials and Methods: The C57BL/6 mouse model of AP was constructed for subsequent studies. Through bioinformatics analysis, the differentially expressed genes related to AP were screened and hub genes were identified. A caerulein-induced AP animal model was constructed to detect the pathological changes of mouse pancreas by HE staining. The concentrations of amylase and lipase were measured. Primary mouse pancreatic acinar cells were isolated and subjected to microscopy to observe their morphology. The enzymatic activities of trypsin and amylase were detected. The secretion of inflammatory cytokines in mouse were measured with the ELISA kits of TNF-α, IL-6 and IL-1ß to determine pancreatic acinar cell damage. A binding site between the Slc2a1 3' UTR region and the miR-455-3p sequence was verified by dual-luciferase reporter assay. The expression of miR-455-3p was quantified by qRT-PCR, and Slc2a1 were detected by western blot. Results: A total of five (Fyn, Gadd45a, Sdc1, Slc2a1, and Src) were identified by bioinformatics analysis, and miR-455-3p/Slc2a1 were further studied. HE staining results showed that the AP models were successfully established by caerulein induction. In mice with AP, the expression of miR-455-3p was reduced, while that of Slc2a1 was increased. In the caerulein-induced cell model, the expression of Slc2a1 was significantly reduced after intervention of miR-455-3p mimics, whereas increased after miR-455-3p inhibitor treatment. miR-455-3p decreased the secretion of inflammatory cytokines in the cell supernatant, reduced the activity of trypsin and amylase, and alleviated the cell damage induced by caerulein. In addition, Slc2a1 3'UTR region was bound by miR-455-3p, and its protein expression was also regulated. Conclusion: miR-455-3p alleviated caerulein-induced mouse pancreatic acinar cell damage by regulating the expression of Slc2a1.

RESUMO

BACKGROUND & AIMS: Pancreatitis is characterized by acinar cell death and persistent inflammation. Ferroptosis is a type of lipid peroxidation-dependent necrosis, which is negatively regulated by glutathione peroxidase 4. We studied how trypsin, a serine protease secreted by pancreatic acinar cells, affects the contribution of ferroptosis to triggering pancreatitis. METHODS: In vitro, the mouse pancreatic acinar cell line 266-6 and mouse primary pancreatic acinar cells were used to investigate the effect of exogenous trypsin on ferroptosis sensitivity. Short hairpin RNAs were designed to silence gene expression, whereas a library of 1080 approved drugs was used to identify new ferroptosis inhibitors in 266-6 cells. In vivo, a Cre/LoxP system was used to generate mice with a pancreas-specific knockout of Gpx4 (Pdx1-Cre;Gpx4flox/flox mice). Acute or chronic pancreatitis was induced in these mice (Gpx4flox/flox mice served as controls) by cerulein injections or a Lieber-DeCarli alcoholic liquid diet. Pancreatic tissues, acinar cells, and serum were collected and analyzed by histology, immunoblot, quantitative polymerase chain reaction, enzyme-linked immunosorbent assay, or immunohistochemical analyses. RESULTS: Supraphysiological doses of trypsin (500 or 1000 ng/mL) alone did not trigger significant cell death in 266-6 cells and mouse primary pancreatic acinar cells, but did increase the sensitivity of these cells to ferroptosis upon treatment with cerulein, L-arginine, alcohol, erastin, or RSL3. Proteasome 26S subunit, non-adenosine triphosphatase 4-dependent lipid peroxidation caused ferroptosis in pancreatic acinar cells by promoting the proteasomal degradation of glutathione peroxidase 4. The drug screening campaign identified the antipsychotic drug olanzapine as an antioxidant inhibiting ferroptosis in pancreatic acinar cells. Mice lacking pancreatic Gpx4 developed more severe pancreatitis after cerulein infection or ethanol feeding than control mice. Conversely, olanzapine administration protected against pancreatic ferroptotic damage and experimental pancreatitis in Gpx4-deficient mice. CONCLUSIONS: Trypsin-mediated sensitization to ferroptotic damage increases the severity of pancreatitis in mice, and this process can be reversed by olanzapine.

RESUMO

Previously we have shown that trypsin, a protein typically involved in digestion, is released from gills of both fresh and saltwater fishes into surrounding water under stress or injury. We have also shown that each species produces trypsin with different specific activities. In this report, using zebrafish as a model, we identified that trypsin induces an aversive response in zebrafish larvae and adult zebrafish. Since Protease-Activated Receptor 2 (PAR2) responds to trypsin, we tested whether the aversive response is dependent on the activation of PAR2 located on the zebrafish skin cells. Zebrafish larvae treated separately with neomycin and zinc sulfate also showed aversive response indicating neuromast, and olfactory cells are not involved in this aversion. Cultured keratinocytes from zebrafish showed a response to trypsin. Zebrafish larvae subjected to knockdown of par2a also exhibited reduced escape response. Similarly, par2a-deficient mutant larvae displayed no response to trypsin. Since it has been shown that stress activates PAR2 and sends signals to the brain as shown by the increased c-fos expression, we tested c-fos expression in adult zebrafish brains after trypsin treatment of adults and found enhanced c-fos expression by qRT-PCR. Taken together, our results show that the trypsin activates PAR2 on keratinocytes signaling the brain, and this pathway of trypsin-induced escape response will provide a unique communication mechanism in zebrafish. Furthermore, since PAR2 activation also occurs in pain/pruritus sensing, this model might be useful in elucidating components of signaling pathways in pain/pruritus.

RESUMO

Celiac disease (CD) is a chronic immune-mediated disorder, characterized by enhanced paracellular permeability across the intestinal epithelium. The complex system of intercellular junctions, including tight junctions (TJs) and adherens junctions (AJs), seals together the epithelial cells to form a continuous layer. The improvements in barrier integrity have been related to modifications in intercellular junction protein expression. Polyamines (spermidine, spermine, and putrescine) actively participate in the modulation of the AJ expression. Both in vitro and in vivo studies have demonstrated that also probiotics can promote the integrity and the function of the intestinal barrier. On these bases, the present work investigated the protective effects exerted by Lactobacillus rhamnosus GG (L.GG) against the pepsin-trypsin-digested gliadin (PTG)-induced enteropathy in jejunal tissue samples of Wistar rats. In particular, the probiotic effects have been evaluated on the intestinal mucosal architecture, polyamine metabolism and intercellular junction protein expression (ZO-1, Occludin, Claudin-1, ß-catenin and E-cadherin). The results from this study indicate that L.GG protects the intestinal mucosa of rats from PTG-induced damage, by preventing the reduction of the expression of the intercellular junction proteins. Consequently, a role for L.GG in the therapeutic management of the gluten-related disorders in humans could be hypothesized.

RESUMO

Interpretation on the effectiveness of potential substances to enhance skeletal muscle regeneration is difficult if an inappropriate vehicle is administered, since vehicle administration can directly enhance or suppress regenerative capacity. In the current study, intramuscular administration of lipid-soluble and water-soluble vehicles into regenerating muscle at the distinct phases of skeletal muscle regeneration (regenerative vs. remodeling) were investigated. Tested vehicles included lipid-soluble [olive oil, (0.1, 1, 5, and 40%) dimethyl sulfoxide (DMSO), and 40% propylene glycol (PG)] and water-soluble [0.9% NaCl, PBS, 0.1% ethanol, and distilled water]. Skeletal muscle regeneration was induced by 1.2% BaCl2 injection to the tibialis anterior muscle of 10-week-old C57BL/6 male mice. Histological features, skeletal muscle stem cell activity, regenerating muscle fiber formation, angiogenesis, extracellular matrix remodeling, and macrophage infiltration were examined. The results revealed repeated administration of 40% DMSO and 40% PG causes significant recurrent muscle injury, which is pronounced during the remodeling phase compared to the regenerative phase. These findings were supported by (1) massive infiltration of F4/80+ macrophages; (2) significant increase of skeletal muscle stem cell re-activation and nascent regenerating muscle fiber formation; (3) excess fibrous formation; and (4) decreased regenerating muscle fiber cross-sectional area. These deleterious effects were comparable to 2% trypsin (degenerative substance) administration and less pronounced with a single administration. Nevertheless, recurrent muscle injury was still presented with 5% DMSO administration but it can be alleviated when 0.1% DMSO was administered during the remodeling phase. In contrast, none of the tested vehicles enhanced regenerative capacity compared with IGF-1 administration. Altogether, intramuscular administration of vehicle containing high concentration of DMSO or PG could impair skeletal muscle regenerative capacity and potentially affect validation of the investigational substance.

RESUMO

PURPOSE OF REVIEW: Genetic risk in chronic pancreatitis is partly due to mutations that cause misfolding of digestive enzymes and elicit endoplasmic reticulum stress. This review examines recent developments in this concept. RECENT FINDINGS: The best characterized misfolding variants in the highly expressed digestive proteases cationic trypsinogen (PRSS1) and carboxypeptidase A1 (CPA1) are strong, causative risk factors for chronic pancreatitis and may be associated with autosomal dominant hereditary pancreatitis. SUMMARY: Properties of misfolding digestive enzyme mutants indicate that endoplasmic reticulum stress is a highly relevant pathological mechanism and a potential therapeutic target in chronic pancreatitis.

RESUMO

INTRODUCTION: Systemic enzyme therapy can play an important role in maintaining normal inflammatory processes within the body and thereby helps support and speed up healing. In the course of the anti-inflammatory action, enzymes degrade damaged cells and necrotic material and, through the inactivation of mediators and toxic products, they restrict the edema and pain. METHOD: The study conducted at Grant Medical College, Mumbai, India was a clinical trial comparing the efficacy and tolerability of three oral enzyme treatment groups-oral tablets containing trypsin:chymotrypsin (TC) (Chymoral Forte®), serratiopeptidase (S) 5 mg oral tablets, and oral enzyme tablets containing trypsin 48 mg, bromelain 90 mg, and rutoside 100 mg (TBR)-to evaluate their healing potential in surgical wounds after orthopedic surgery. RESULTS: A total of 75 patients were screened, randomized, and divided into three groups in 1:1:1 ratio receiving either of the three treatments. In the TC group, erythema was significantly reduced from 3.44 on day 3 to 1.16 on day 10 (p < 0.01). There was significantly better reduction in erythema scores in the TC group as compared to S and TBR groups (p < 0.05) at each follow-up visit. Similarly reduction in the local irritation, wound discharge, edema, induration, and tenderness score with TC treatment at the end of the study was significantly higher than that observed in the other two groups. In addition TC showed significant reduction in pain on the VAS scale (p < 0.01). Global assessment of response to therapy for efficacy and tolerability was reported to be good to excellent in 88% and 92% of the patients on TC as compared to 12% and 8% with S and 12% and 8% with TBR. CONCLUSION: TC provides a better resolution of symptoms of inflammation after orthopedic surgery as compared to S and TBR, thus facilitating better wound healing. Further studies are warranted to confirm the findings. TRIAL REGISTRATION: Clinical Trial Registry of India (Reg. No. CTRI/2011/07/001920).

RESUMO

INTRODUCTION: Vigorous and prolonged exercise such as marathon running increases inflammatory markers and the risk of upper respiratory illness (URI) in athletes. Nutritional supplements are being tested as countermeasures of exercise-induced inflammation and immune dysfunction. METHODS: In this prospective randomized, double-blind, placebo-controlled phase I trial, healthy male runners (N = 138, age 42 ± 11 yr) were supplemented with rutoside (600-1200 mg·d) and hydrolytic enzymes (540-1080 mg·d bromelain, 288-576 mg·d trypsin) (WOB) or placebo (PL) for 1 wk before and 2 wk after the Munich Marathon 2013. Blood samples were collected 5 wk prerace and immediately, 24 h, and 72 h postrace and analyzed for inflammation biomarkers (interleukins [IL] 6 and 10, high-sensitivity C-reactive protein, and leukocytes). URI rates, assessed by the Wisconsin Upper Respiratory Symptom Survey, were compared between the study groups during the 2-wk period after the marathon race. URI was defined if the Wisconsin Upper Respiratory Symptom Survey score was equal or greater than seven, representing either one severe symptom or seven mild symptoms. RESULTS: Immediately postrace, the increase of IL-6 was not significantly different between the WOB and the PL groups (median [interquartile range]: WOB, 33.8 [22.5-58.8] ng·L; PL, 35.6 [24.8-61.29] ng·L; P = 0.758). No significant group differences were observed for increases of IL-10, high-sensitivity C-reactive protein, or leukocytes pre- to postrace (all P > 0.05). From race day until 2 wk after the marathon race, the percentage of individuals with at least one URI did not significantly differ between the groups (WOB, 50.0%; PL, 51.5%; P = 0.859). CONCLUSION: Supplementation with rutoside and hydrolytic enzymes before and after a marathon race did not attenuate postrace inflammation or decrease URI incidence in nonelite male marathon runners.

RESUMO

BACKGROUND AND AIMS. Gastroesophageal reflux disease (GERD) is associated with impaired epithelial barrier function. However, the influence of acid and/or bile acids on human esophageal epithelial barrier function and the tight junction (TJ) proteins has not been fully elucidated. The aim of the study is to investigate the esophageal barrier function and TJ expression in healthy subjects and patients with GERD. The functionality of esophageal mucosa exposed to bile salt deoxycholic acid (DCA) and trypsin has been studied in vitro. MATERIAL AND METHODS. Endoscopic biopsies from healthy controls and patients with GERD-related symptom with endoscopic erosive signs, as well as esophageal mucosa taken from patients undergoing esophagectomy were evaluated in Ussing chambers and by western blot and immunohistochemistry. RESULTS. The esophageal epithelium from GERD patients had lower electrical resistance and higher epithelial currents than controls. Claudin-1 and -4 were significantly decreased in GERD patients. The bile salt DCA in the low concentration of 1.5 mM and trypsin increased the resistance and claudin-1 expression, while the higher concentration of 2.5 mM DCA and trypsin decreased the resistance and the claudin-3, -4 and E-cadherin expressions. CONCLUSION. In addition to acidic reflux, duodenal reflux components, such as bile salts and trypsin, have the potential to disrupt the esophageal barrier function, partly by modulating the TJ proteins. However, the expression of TJ is dependent on both the refluxed material as well as the concentration of the bile salt.

RESUMO

In the work you can find the results of the research on modeling of acute experimental pancreatitis caused by injecting solution of tripsin and vipera berus venom. All the visceral organs are involved, that corresponds to common to the human and animal pathological processes (induction of proteolysis and DIC-syndrome). The results of the research show and prove the effectiveness of sandostatin and anti-ophidic serum influence on the proteolytic processes, blood coagulation. Thus, this research gives the opportunity to possibly expand the usage of sandostatin and anti-ophidic serum on treatment diseases with the participation of cascade proteolytic processes.

RESUMO

BACKGROUND: Wobe Mugos(®) is an enzyme preparation containing the proteases trypsin and papain from the pancreatic calf and commonly used in complementary medicine. From non-randomized studies, its multiple favorable effects including the reduction of adverse events from radiotherapy and chemotherapy in oncology patients have been reported. METHODS: Patients with invasive breast cancer receiving adjuvant or palliative chemotherapy between 2005 and 2006 and who were scheduled for at least two further cycles of this specific chemotherapy were included in this pilot study. A specific toxicity of at least grade 2 using the NCI common toxicity criteria which occurred during the preceeding cycle and was relevant to the patient was recorded. This specific toxicity, e.g. grade 2 emesis, was again evaluated after two analogously administered further chemotherapy cycles in which Wobe Mugos(®) had been coadministered. The hypothesis was that specific toxicites of individual patients will be reduced by this enzyme therapy. The majority of the 57 consecutive patients received palliative chemotherapy. Peroral enzyme therapy was coadministered with two uncracked coated tablets three times daily on all days of a chemotherapy cycle except on the day of chemotherapy administration. RESULTS: Tolerability was good. Positive and neutral effects on toxicity parameters were observed in 11 and 42 patients, respectively, and a negative influence in 4 women. CONCLUSION: We observed only a marginal influence of Wobe Mugos(®) in patients with breast cancer who had experienced at least a grade 2 toxicity in the preceding cycle and who received two further identical cycles of this chemotherapy in conjunction with the enzyme preparation. Randomized studies on homogenous patient populations are necessary.

RESUMO

The need of an enzymatic cleaner for soft contact lens care with an improved ocular safety and stability profile led us to evaluate the use of nanoparticles (NPs) of poly(D,L-lactide-coglycolide) (PLGA) and methyl trypsin (MT). NPs were prepared by double emulsion-solvent evaporation technique. A factorial design was performed to select the lactic acid proportion in the copolymer and conditions of the second sonication. The increment in proportion of lactic acid provided higher particle size results. When the time of second sonication was decreased, the entrapment efficiency (EE) increased. PLGA 50:50 NPs were chosen for further development since PLGA 50:50H NPs settled fast with different particle size in the sediment and PLGA 75:25 NPs led to form aggregates. The addition of glycerol to the NPs provided the highest EE of MT (>90%) while the addition of Tetronic 1304 promoted the fast release of enzyme initially and decreased the zeta potential (zeta) up to neutral values after gamma irradiation. NPs are expected to be effective as a lens care cleaner after 3 days or even longer with a very low quantity of enzyme released. Formulations showed an acceptable irritation ocular tolerance after in vitro HET-CAM test and in vivo Draize test.

METHODS: Fifty-two female patients classified as C2,s or C2,3,s (CEAP classification) were allocated consecutively in three groups: Cirkan (40 mg of the root extract of Ruscus aculeatus + 100 mg of flavonoid hesperidine methylchalcone + 200 mg of vitamin C per pill); elastic compression stockings (ECS) and no treatment (NT). Diameters were determined by duplex ultrasound and perimeter with Leg-O-Meter. RESULTS: After treatment, Cirkan significantly decreased popliteal vein and great saphenous vein (GSV) diameters bilaterally and ECS decreased popliteal vein diameter bilaterally and GSV and varices only on the left limb. Perimeters changed only with ECS. Clinical scores changed between Cirkan x NT and ECS x Cirkan. Disability score varied for ECS x NT and Cirkan x NT. chi2 test detected different distribution frequency for C3 and C2 classes according to treatment: ECS (both limbs) and Cirkan (only left limb). Varices and anatomical scores did not change. CONCLUSIONS: ECS emerges as the most effective clinical treatment tested but improvements with Cirkan on vein diameter and CEAP class were also observed. Clinical scores improved due to pain relief and edema reduction (ECS). These findings point to a positive effect of Cirkan, suggesting that venotonic drugs should be taken into account in the treatment of CVD.

RESUMO

Foram utilizados 64 leitões, submetidos a oito tratamentos: ração com leite em pó (LP), três rações com níveis crescentes de plasma suíno (PS), três rações com níveis crescentes de ovo inteiro (OI) eração com alto nível de farelo de soja (FS). Foi coletado sangue dos animais aos 27 e 34 dias de idade para avaliação dos parâmetros sangüíneos, e aos 28 e 35 dias de idade quatro animais por tratamento foram abatidos para coleta do pâncreas e posterior determinação do peso absoluto (PA) e peso relativo (PR) do pâncreas e da atividade datripsina (AT). Os tratamentos não influenciaram significativamente o PA e a AT. Verificou-se efeito significativo dos níveis crescentes de PS,com redução linear dos leucócitos e aumento do volume globular,aos 27 dias; enquanto aos 34 dias, observou-se aumento linear das hemácias. Aos 27 dias, os animais arraçoados com níveis de PS apresentaram menor percentagem de eosinófilos do que aqueles arraçoados com níveis de OI. A utilização de plasma suíno promoveu menor estímulo à resposta imune, enquanto que a utilização de ovo inteiro promoveu maior resposta humoral dos leitões


Were used 64 piglets submitted eight treatments: ration with skim milk (SM), three rations with crescent levels of swine plasma (SP),three rations with whole egg (WE) and a ration with high inclusion of soybean meal (SB). Were monitored the blood parameters (BP) in pigs at 27 and at 34 days of age. The piglets were slaugther at 28 and at 35 days of age, for collections pancreas and posterior mensurements of absolut (AW) and relative weigth (RW) of pancreas and trypsinactivity (TA). Treatments not influencied AW and TA. Significant effect of the crescent levels was verified of SP, with lineal reduction ofthe leukocytes and increase of the globular volume, to the 27 days;while to the 34 days, lineal increase of the hematias was observed. At27 days, animals feds rations with crescent levels of SP have inferior percentage of e osinophils than others that consumed crescent levelsof WE. The utilization of SP promoted smaller stimulus to the immune reply, while the use of WE promoted larger humoral replyof the piglets

RESUMO

We conducted an open-label study of 109 untreated patients who had excessive or impacted cerumen. Our goal was to evaluate the safety and efficacy of Sofenz Cerumenolytic Solution, a methyltrypsin-containing earwax removal solution. Each patient's external auditory canal was filled with Sofenz for 15 minutes. The primary measure of efficacy--visibility of the tympanic membrane--was assessed after the solution had been drained from the canal and again after the canal had been irrigated with lukewarm water. If the tympanic membrane was not completely visible following either application, the procedure was repeated. A safety examination was conducted 1 to 3 days after treatment. Secondary outcomes measures included relief of otologic symptoms (e.g., hearing loss, tinnitus, etc.) and patients'overall satisfaction with treatment. Immediately after treatment, we found that the external auditory canal was completely visible in 81 patients (74.3%) after 1 application of Sofenz and subsequent irrigation, and in 98 patients (89.9%) after 2 applications of each. At the safety follow-up visit, we determined that the number of otologic symptoms had declined by 93.2%. A self-reported assessment completed by each patient following the procedure revealed a high degree of satisfaction with treatment. A total of 58 adverse events were reported, but only 16 were directly related to treatment, and all were transient and either mild or moderate. We conclude that 1 or 2 applications of Sofenz followed by irrigation with lukewarm water is a safe, well-tolerated, and effective treatment for excessive or impacted cerumen in the external auditory canal.

RESUMO

Active thrombin is found in the airways of patients with a variety of inflammatory lung diseases. However, whether thrombin contributes to the pathologies of these diseases is unknown, although thrombin is a potent inflammatory mediator in other organ systems. In the present study we have assessed the acute inflammatory effect of inhaled thrombin and investigated the possible receptors mediating any effects in mice. Thrombin (200-2000 U kg(-1) intranasally), induced the recruitment of a small, but significant, number of neutrophils into the airways as assessed by differential counts of cells retrieved by bronchoalveolar lavage (BAL). This small response was mimicked by peptide agonists of proteinase-activated receptor-4 (PAR(4); GYPGKF, AYPGKF; 2-20 mg kg(-1)), but not PAR(1) (SFLLRN; 2-20 mg kg(-1)). By contrast, trypsin (200-2000 U kg(-1)) caused profound inflammation and lung damage. Concentrations of tumour necrosis factor-alpha (TNF-alpha) were elevated in BAL fluid from thrombin-treated mice, and a TNF-alpha-neutralising antibody inhibited the influx of neutrophils in response to thrombin. Although isolated alveolar macrophages appeared to express PAR(1)- and PAR(4)-immunoreactivity, these cells failed to release TNF-alpha above baseline levels in response to thrombin, trypsin or any of the peptide PAR agonists. Neither thrombin (2000 U kg(-1)) nor trypsin (200 U kg(-1)) modified the airway neutrophilia in response to intranasal bacterial lipopolysaccharide (LPS; 100 micrograms kg(-1)). In conclusion, exogenous thrombin has only a modest acute inflammatory action in the lung that appears to be mediated by PAR(4) and involve release of TNF-alpha from an unknown source.

RESUMO

OBJECTIVE: To compare the effectiveness and safety of the triple combination Phlogenzym (rutoside, bromelain, and trypsin) with double combinations, the single substances, and placebo. DESIGN: Multinational, multicentre, double blind, randomised, parallel group design with eight groups structured according to a factorial design. SETTING: Orthopaedic surgery and emergency departments in 27 European hospitals. PARTICIPANTS: A total of 721 patients aged 16-53 years presenting with acute unilateral sprain of the lateral ankle joint. PRIMARY EFFICACY CRITERIA: (a) Pain on walking one or two steps, as defined by the patient on a visual analogue scale. (b) The range of motion, as measured by the investigator and expressed as a sum of flexion and extension. (c) The volume of the injured ankle measured with a volometer. RESULTS: At the primary end point at seven days, the greatest reduction in pain was in the bromelain/trypsin group (73.7%). The Phlogenzym group showed a median reduction of 60.3%, and the placebo group showed a median reduction of 73.3%. The largest increase in range of motion (median) was in the placebo group (60% change from baseline). The Phlogenzym group showed a median increase of 42.9%. The biggest decrease in swelling was in the trypsin group (3.9% change from baseline). The Phlogenzym group showed a -2.30% change from baseline and the placebo group a -2.90% change. In the subgroup analysis of patients who did not use a Caligamed brace, Phlogenzym was superior to placebo for the summarising directional test of the primary efficacy criteria (MW = 0.621; LB-CI 0.496; p = 0.029; one sided Wei-Lachin procedure). The vast majority of doctors and patients rated the tolerability of all treatments tested as very good or at least good. CONCLUSIONS: Phlogenzym was not found to be superior to the three two-drug combinations, the three single substances, or placebo for treatment of patients with acute unilateral sprain of the lateral ankle joint. The small subgroup of patients treated without the support of a Caligamed brace showed evidence of superiority of Phlogenzym over placebo. Further research is warranted to study this effect of Phlogenzym in patients treated without ankle support.

RESUMO

An assessment was carried out of clinical effectiveness of the drug phlogenzym in 74 patients with remitting, remitting-progressive, and secondary progressive course of multiple sclerosis. Phlogenzym intake for up to one to three years resulted in decline in the incidence of complications, with their degree having come to be lower, duration of remissions longer, progression of the illness slowed down. The data secured suggest to us that phlogenzym is a safe agent. It can, we believe used in a therapeutic regimen for those patients presenting with remitting and remitting-progressive types of the course of the disease.
