25. The preventive effects of natural adjuvants, G2 and G2F on tracheal responsiveness and serum IL-4 and IFN-γ (th1/th2 balance) in sensitized guinea pigs
OBJECTIVE:The effects of natural adjuvants on lung inflammation and tracheal responsiveness were examined in sensitized guinea pigs.METHODS:The responses of guinea pig tracheal chains and the serum levels of interleukin-4 and interferon-gamma were examined in control pigs and three other groups of guinea pigs: the sensitized group and two other sensitized gr

26. The putative role of ovary removal and progesterone when considering the effect of formaldehyde exposure on lung inflammation induced by ovalbumin
OBJECTIVE: Formaldehyde exposure during the menstrual cycle is known to affect the course of allergic lung inflammation. Because our previous data demonstrated that formaldehyde combined with an ovariectomy reduced allergic lung inflammation, we investigated the putative role of ovary removal and progesterone treatment when considering the effect of formald

27. pH in exhaled breath condensate and nasal lavage as a biomarker of air pollution-related inflammation in street traffic-controllers and office-workers
OBJECTIVE: To utilize low-cost and simple methods to assess airway and lung inflammation biomarkers related to air pollution. METHODS: A total of 87 male, non-smoking, healthy subjects working as street traffic-controllers or office-workers were examined to determine carbon monoxide in exhaled breath and to measure the pH in nasal lavage fluid and exhaled

28. Effects of atropine and propranolol on lung inflammation in experimental envenomation: comparison of two buthidae venoms
Background Previous works had shown that scorpion venom induced neurotransmitter elevation and an inflammatory response associated with various anatomo-pathological modifications. The most dangerous scorpions species in Algeria responsible for these effects are Androctonus australis hector (Aah) and Androctonus amoreuxi (Aam). Results Comparison of the phys

29. Simvastatin attenuates neutrophil recruitment in one-lung ventilation model in rats
PURPOSE: To investigate the anti-inflammatory effects of simvastatin in rats undergoing one-lung ventilation (OLV) followed by lung re-expansion. METHODS: Male Wistar rats (n=30) were submitted to 1-h OLV followed by 1-h lung re-expansion. Treated group received simvastatin (40 mg/kg for 21 days) previous to OLV protocol. Control group received no treatment

30. Tratamento com inibidor da Rho quinase em cobais com inflamação pulmonar alérgica crônica: modulação da inflamação eosinofílica, da expressão de citocinas inflamatórias, da matriz extracelular e do estresse oxidativo no parênquima pulmonar / Treatment with Rho-kinase inhibitor in guinea pigs with chronic allergic inflammation: modulation of eosinophilic inflammation, expression of inflammatory cytokines, extracellular matrix and oxidative stress in lung tissue
RATIONALE: Previous studies with Rho-kinase inhibitors suggest a beneficial influence of these drugs in asthma. The relevance of distal lung tissue in functional asthmatic impairment has been intensely emphasized. There have not been any previous studies evaluating the effects of these inhibitors on the modulation of distal lung mechanics and histopathologic

31. Avaliação da resposta inflamatória pulmonar de suínos submetidos a lesão pulmonar aguda induzida por ácido clorídrico e tratados com solução salina hipertônica / Lung inflammatory response in pigs submitted to acute pulmonary injury by hydrochloric acid and treated with hypertonic saline
INTRODUÇÃO: A lesão pulmonar aguda (LPA) decorrente de aspiração do conteúdo gástrico é freqüente em pacientes com nível de consciência comprometido e depressão dos reflexos de vias aéreas. A solução salina hipertônica (HS) a 7,5% apresenta resultados ainda controversos quanto ao seu potencial efeito protetor na resposta inflamatória pulmona

32. Efeito da pentoxifilina e da solução salina hipertônica na isquemia/reperfusão intestinal e suas consequências no pulmão: estudo experimental em ratos / The effect of pentoxifylline and hypertonic saline in intestinal ischemia / reperfusion and their consequences in the lung: an experimental study in rats
Isquemia e reperfusão (I/R) de vasos mesentéricos que acarretam insuficiência vascular aguda são acompanhadas de insuficiência em múltiplos órgãos e estão associados a altas morbidade e mortalidade. Os benefícios da solução hipertônica e da pentoxifilina foram testados isoladamente e em conjunto para melhorar o fluxo sanguíneo e o estado de oxi

33. Estudo da ativação eosinofílica e de matriz extracelular de tecido pulmonar periférico em cobaias com inflamação alérgica pulmonar: efeitos do tratamento com dexametasona e antagonista do receptor do cisteinil-leucotrieno D4
Aims: Compare the effects of montelukast or dexamethasone treatments on eosinophilic recruitment, eotaxin, RANTES, fibronectin, IGF-I and NF-B positive cells of distal lung parenchyma and also in airway walls of guinea pigs (GP) with chronic allergic inflammation. Methods: GP were inhaled with ovalbumin (OVA group-2x/week/4weeks). After 4th inhalation, GP we

34. Evaluation of lung function and histopathology in an experimental model of chronic allergic pulmonary inflammation: effects of reduced cholinergic function in genetically modified mice / Avaliação da função e da histopatologia pulmonar em modelo experimental de inflamação pulmonar alérgica crônica: efeitos da redução da função colinérgica em camundongos geneticamente modificados
INTRODUÇÃO: A Asma Brônquica é caracterizada por obstrução ao fluxo aéreo, reversível ou não, e processo inflamatório pulmonar, caracterizado principalmente por eosinofilia. A persistência da inflamação pode induzir processo de reparo pulmonar associado à redução progressiva da função pulmonar. A recente descrição do sistema colinérgico

35. ATIVIDADE DE ECTOENZIMAS E DE COLINESTERASES E BIOMARCADORES DE ESTRESSE OXIDATIVO EM PACIENTES COM CÂNCER DE PULMÃO / ACTIVITY OF ECTOENZIMAS AND CHOLINESTERASES AND OXIDATIVE STRESS BIOMARKERS IN PATIENTS WITH LUNG CANCER
Lung cancer has become one of the most commonly diagnosed neoplastic diseases, as well as one of the most lethal worldwide, characterized, therefore, as a public health problem. This spread of lung cancer in the world population, which is clearly seen in statistics, is closely related to smoking, and smoking is considered one of the main risk factors that le

36. Efeitos do etil-piruvato no tratamento da resposta inflamatória da lesão pulmonar na pancreatite aguda necrosante induzida em ratos. / Effects of ethyl-pyruvate in the inflammatory response of lung injury in experimental acute pancreatitis in rats.
INTRODUCTION: Severe acute pancreatitis (AP) is characterized by hemodynamic alterations and systemic inflammatory response leading to a high mortality rate. In AP the inappropriate activation of pancreatic enzymes plays an important role in pancreas autodigestion and in the inflammatory mechanisms responsible for the systemic response of the disease.
