Polyhexamethylene guanidine hydrochloride (PHMG-HCl), an antimicrobial additive in humidifier disinfectants, was associated with the pulmonary disease outbreak in South Korea. However, PHMG-mediated oxidative stress has only been studied in vitro. Here, we evaluated PHMG-induced oxidative
Platelet aggregation induced by ADP can be inhibited by plasma from uremic patients or by toxins isolated from their plasma, e.g. guanidinosuccinic acid, methylguanidine, phenol and hydroxyphenylacetic acids. Since these chemical substances can interfere with energy metabolism in tissues other than
Wild-type human cystatin C is directly involved in pathological fibrils formation, leading to hemorrhage, dementia and eventually death of people suffering from cerebral amyloid angiopathy. Some studies on cystatin C oligomerization have been already done but some points are still unclear. In order
To evaluate the efficacy of adjunctive polyhexamethylene guanidine (PHMG) phosphate irrigation in periodontal treatment.The subjects comprised 59 patients with severe chronic periodontitis. Plaque index, bleeding on probing (BOP) and pocket probing depths The major side effect of thrombolytic therapy is bleeding; however, the pathogenesis of this potential complication is not well understood. Accordingly, we examined the effects of aspirin and recombinant human tissue-type plasminogen activator (rt-PA) on serial template bleeding times and on
A series of the aryl-substituted N'-2-(2-hydroxy-2-phenyl)ethyl derivatives of N"-methanesulfonyl-N-2-((5-dimethylaminomethyl or 5-methylaminomethyl) furfurylthio)ethylguanidine have been synthesized as potential antisecretory and mucosal protective antiulcer agents. The synthetic routes involves,
A liquid phase hybridization format has been adapted for the identification of bluetongue virus (BTV) with respect to serogroup and serotype. In this paper we present experiments which demonstrate the identification of bluetongue virus with respect to both serogroup and serotype. BTV
OBJECTIVE
Nafamostat mesilate (NM) is a guanidine acid derivative which is synthesized in Japan as an antifibrinolytic drug. It has been successfully used to decrease blood loss and blood product requirement in cardiac operations. As there have been some reports that insufficient heparinization
Acid aspiration or intrapulmonary instillation of gastric particles causes lung inflammation leading to acute lung injury (ALI). Hypercapnia exerts different effects on ALI caused by various insults. The effects of hypercapnia on lung inflammation and injury due to acid aspiration are yet to be
OBJECTIVE
Acute lung injury (ALI) is a serious clinical problem. We investigated the pathogenetic mechanisms of ALI caused by leptospirosis.
METHODS
The study included five cases of leptospirosis. We monitored the arterial pressure (AP) and heart rate (HR) and analysed the AP and HR variabilities
We aim to test the hypothesis that hypercalcemia produces pulmonary edema (PE) and to elucidate the mechanism. Experimentations were carried out in conscious rats and isolated perfused rat lungs. We evaluated PE by lung weight changes, protein concentration in bronchoalveolar lavage, dye leakage,
Phorbol myristate acetate (PMA) causes acute lung injury (ALI). The present study was designed to elucidate the role of nitric oxide (NO), inducible NO synthase (iNOS), neutrophil elastase (NE) and other mediators in the ALI caused by PMA. In isolated rat's lungs, PMA at various doses (1, 2 and 4
From muscle extracts of the European hedgehog, Erinaceus europaeus, an antihemorrhagic factor, erinacin, was purified by ammonium sulfate precipitation followed by chromatography on DEAE-cellulose, hydroxylapatite and gel filtration columns. A purification of approx. 1400-fold was achieved with an
BACKGROUND
The diagnosis and the therapy of in vivo hemostasis activation is of great clinical importance. Artefactual changes of the hemostasis (i.e., coagulation or fibrinolysis) in vitro have to be prevented. Usual in vitro anticoagulation by sodium citrate does not fully inhibit coagulation--or
A neutral protease with kininogenase activity was isolated from human polymorphonuclear (PMN) leukocytes by cation exchange chromatography and gel filtration. The protease appears heterogeneous by cation exchange chromatography, isoelectric focusing and cationic disc gel electrophoresis, but
