polyethylene glycol-superoxide dismutase

07/01/1993 - "The narrow therapeutic dose range of PEG-SOD in this study and similar findings of SOD in other investigations may contribute to the inconsistent protective effects of SOD preparations in ischemia-reperfusion injury in the literature."
01/01/1999 - "PEG-SOD can effectively attenuate hepatic ischemia/reperfusion injury by inhibiting OFR-mediated lipid peroxidation."
01/01/1999 - "Polyethylene glycol-superoxide dismutase inhibits lipid peroxidation in hepatic ischemia/reperfusion injury."
06/17/2002 - "(4) On cerebral ischemia/reperfusion injuries the effect of PEG-SOD was uncertain, also due to the difficulty of cerebral cell penetration. "
12/01/1992 - "These data demonstrate that high, but not low, doses of polyethylene glycol superoxide dismutase significantly reduce reperfusion injury when administered 24 hours before initiation of global ischemia. "

12/01/1992 - "We tested the myocardial protective effect of polyethylene glycol superoxide dismutase administered once, 24 hours before ischemia. "
06/01/1991 - "Ten of these animals received 25,000 U/kg of PEG-SOD 24 hours before aortic occlusion and two additional doses of 10,000 U/kg, one before and one subsequent to spinal ischemia. "
10/01/1993 - "To determine the effect of preischemic versus postischemic treatment with PEG-SOD, each piglet received two i.v. drug injections of either 30,000 U PEG-SOD or an equal volume of PEG diluent in a randomized, blinded fashion before ischemia and just before reperfusion. "
12/01/1994 - "Moreover, PC-SOD (50,000 U/kg) had an inhibitory effect on ischemia-reperfusion paw edema in mice, whereas neither unmodified SOD nor PEG-SOD had any effect. "
12/01/1992 - "These data demonstrate that high, but not low, doses of polyethylene glycol superoxide dismutase significantly reduce reperfusion injury when administered 24 hours before initiation of global ischemia. "

03/01/1993 - "Protection against O2 toxicity by PEG-SOD insufflation was associated with attenuated O2-induced pulmonary injury as evidenced by a reduced volume of pleural effusion. "
02/01/1989 - "Rats pretreated with the long-lived conjugates PEG-inactivated-SOD + PEG-inactivated-CAT or PEG-albumin also had decreased acute oxidative edematous lung injury compared with rats pretreated with PEG, SOD + CAT + PEG, SOD + CAT, or saline. "
01/01/1993 - "On the other hand, the death rate and lung injury were markedly prevented by polyethylene glycol conjugated SOD (PEG-SOD) pretreatment prior to DEP administration. "
02/01/1992 - "We examined whether polyethylene glycol-conjugated superoxide dismutase (PEG-SOD) attenuates lung injury in Escherichia coli-treated guinea pigs. "
07/01/1990 - "This study evaluated the effects of polyethylene glycol-conjugated superoxide dismutase (PEG-SOD) in re-expansion pulmonary edema, a unilateral lung injury due in part to re-oxygenation of hypoxic, collapsed lung tissue. "

02/01/1997 - "We found that the rate of development of diaphragm fatigue was much greater in saline and denatured PEG-SOD-treated groups than for animals pretreated with either PEG-SOD or DMSO, with force falling to 23 +/- 4, 21 +/- 4, 50 +/- 7, and 47 +/- 6% of its initial value, respectively, over a 2-h period of electrophrenic stimulation in these four groups of animals (p < 0.01). "
11/01/2003 - "Intravenous infusion of phentolamine (10 mg/kg) or PEG-SOD (2,000 U/kg) in OZR altered neither fatigue rates nor active hyperemia from untreated levels; however, combined infusion improved performance and hyperemia, although not to levels in LZR. "
02/01/1997 - "To accomplish this, we compared the rate of development of fatigue of the electrically stimulated diaphragm in four groups of dogs: (1) animals given intravenous polyethylene glycol adsorbed superoxide dismutase (PEG-SOD, 2,000 units/kg) 1 h before a fatigue trial; (2) a group given intravenous dimethylsulfoxide (DMSO, 0.5 ml/kg of a 50% solution) before fatigue; (3) a group given saline before fatigue; and (4) a group treated with denatured PEG-SOD (2,000 units/kg) before fatigue. "

07/01/1989 - "[Experimental study on renal protection against damage in kidneys subjected warm ischemia--protective effect of FOY, SOD, and PEG-SOD on ischemic acute renal failure]."
