Polyhexamethylene guanidine (PHMG) phosphate is a competitive disinfectant with strong antibacterial activity. However, epidemiologists revealed that inhaled PHMG-phosphate may increase the risk of pulmonary fibrosis associated with inflammation, resulting in the deaths of many people, including
Ten N-(4-propoxyphenyl)-N'-(4-chlorophenethyl)-N"-substituted guanidines were synthesized from the corresponding 1-(4-propoxyphenyl)-3-substituted thiocarbamides and evaluated for anti-inflammatory and antiproteolytic properties. All substituted guanidines (50 mg/kg) provided 1-31% protection
Oleanolic acid acetate (OAA), triterpenoid compound isolated from Vigna angularis (azuki bean), has been revealed anti-inflammatory in several studies. We investigated the effects of OAA against polyhexamethylene guanidine phosphate (PHMG-P)-induced pulmonary inflammation and fibrosis in mice. OAA
The influence of creatinine, urea and guanidine injection on the course of an artifically induced inflammatory reaction has been studied in rats. The formalin and bolus alba edema served as inflammatory models. It was shown that the inflammatory reaction was not significantly altered by urea. By
The guanidine compound ME10092 (1-(3,4-dimethoxy-2-chlorobenzylideneamino)-guanidine) is known to possess anti-radical and anti-ischemic activity but its molecular targets have not been identified. This study investigated whether ME10092 regulates the nuclear factor kappa B (NF-kappaB)-mediated
p38 mitogen-activated protein kinase (MAPK) signaling is known to be increased in chronic obstructive pulmonary disease (COPD) macrophages. We have studied the effects of the p38 MAPK inhibitor
A series of novel guanidine derivatives were synthesized in three steps and their anti-inflammatory activities in vitro and in vivo evaluated. 2-Aminopyridin-3-ol (1) was reacted with thiophosphoryl chloride (2) to give a monochloride (3). It was further reacted with cyanamide to afford the
Polyhexamethylene guanidine (PHMG) phosphate was used as a disinfectant for the prevention of microorganism growth in humidifiers, without recognizing that a change of exposure route might cause significant health effects. Epidemiological studies reported that the use of humidifier disinfectant
Human proximal colon from patients with inflammatory bowel disease and from controls was studied by two techniques to detect tumor-associated antigen expression. A panel of four murine monoclonal antibodies that recognize tumor-associated antigens was used to test purified colonic mucins for epitope
In an experimental arthritis induced by injection of bovine serum albumin or egg albumin into the joints of previously immunized animals, it has been demonstrated that the major portion of the radioactively labeled antigens injected was localized to avascular collagenous tissues in the joint, i.e.,
Aminoglycosides (AGs) modulate nociceptors and ionic channels expressed in sensory neurons. The AG applied in situ could be useful to alleviate hyperalgesia in animal models of inflammatory pain. We tested streptomycin (ST) and neomycin (NEO) as analgesic agents applied in situ in rat paw
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
Capsules have been prepared based on a polyanion blend of sodium alginate and sodium cellulose sulphate, gelled in the presence of calcium chloride and sodium chloride. In a second step a membrane was formed via the addition of polymethylene-co-guanidine (PMCG), an oligocation. A mechanistic study
BACKGROUND
The blunted immune response upon stimulation in chronic renal failure (CRF) is often coupled to a baseline inflammatory status which has been related to atherogenesis. Uremic biologic fluids and several specific uremic retention solutes alter cell-mediated immune responses, as well as the
