BACKGROUND AND PURPOSE Neurocognitive dysfunction complicates coronary artery bypass surgery. Erythropoietin may be neuroprotective. We sought to determine whether human recombinant erythropoietin would reduce the incidence of neurocognitive dysfunction after surgery. METHODS We randomly assigned 32 elective first-time coronary artery bypass graft patients to receive placebo or 375 U/kg, 750 ...

Purpose: To explore the effect of recombinant human erythropoietin (r-HuEPO) on apoptosis in rats after traumatic brain injury. Methods: A total of 48 traumatic brain-injured Sprague Dawley (SD) rats were obtained by improved Feeney’s traumatic brain injury model, and were randomly divided into four groups: normal salinetreated rats (control) and rats treated with r-HuEPO at doses of 1000 U/kg,...

Two studies investigated the effect of a thermo-tolerant E.coli-derived phytase (QuantumTM) on performance and bone parameters of broilers fed diets varying in content of available phosphorus (AP), metabolizable energy (ME) and total lysine (TLYS). A 48-day floor pen trial used 80 pens of 16 male broilers fed corn/soya/meat-bone meal based diets formulated to commercial averages (AS) or below. ...

Consensus phytase is a new biosynthetic, heat-stable enzyme derived from the sequences of multiple homologous phytases. Two experiments were conducted to determine its effectiveness, relative to inorganic P and a mutant enzyme of Escherichia coli phytase (Mutant-EP), in improving dietary phytate-P availability to pigs. In Exp. 1, 36 pigs (3 wk old, 7.00 +/- 0.24 kg of BW) were fed a low-P corn-...

Let U(KG) be the group of units of the group ring KG of the group G over a commutative ring K . The anti-automorphism g 7→ g of G can be extended linearly to an anti-automorphism a 7→ a∗ of KG . Let S∗(KG) = {x ∈ U(KG) | x∗ = x} be the set of all symmetric units of U(KG) . We consider the following question: for which groups G and commutative rings K it is true that S∗(KG) is a subgroup in U(KG...

background: to attain whether the effects of low and high doses of estrogen progesterone luteinizing hormone (lh) and follicle stimulating hormone (fsh) in acute and chronic administration were related to oxidant and antioxidant parameters in rat uterine tissue as well as cyclooxygenase-1 (cox-1) activity. materials and methods: acute and chronic administration of estrogen (1 and 5 mg/ kg) prog...

The study was conducted to investigate the effects of different levels of xylanase on performance, blood parameters, intestinal morphology, microflora and digestive enzyme activities of broilers. The wheat-based diets were supplemented with 0, 500, 1,000, 5,000 U/kg xylanase. Xylanase supplementation significantly (p<0.05) improved the feed:gain ratio of broilers from 1 to 21 d and 1 to 42 d. S...

Baker1, 1University of Illinois at Urbana-Champaign, 2United Feeds, Inc., Sheridan, IN, 3Cornell University, Ithaca, NY. Three assays were done to investigate the phosphorus (Pi)-releasing efficacy of an E. coli phytase (ECP, produced by Phytex LLC), relative to Natup...

An enzyme L-lysine-A-oxidase has been obtained from Trichoderma harzianum Rifai F-180. The analysis of serum from CBA mice immunized five times with native L-lysine-A-oxidase intravenously, at a dose of 35 U/kg, showed that the preparation had virtually no effect on the immune response to Tdependent antigen. L-lysine-A-oxidase at a dose of 35 U/kg administered twice intradermally has no effect ...

BACKGROUND Accidental intravenous introduction of commercial bovine thrombin (BT) during use of fibrin glue may result in profound hypotension. Commercial human thrombin (HT) is now available. This study compared the effects of intravenous BT versus HT in swine. METHODS Swine received 30 U/kg BT, 60 U/kg BT, 30 U/kg HT, or 60 U/kg HT intravenously. Mean arterial pressure (MAP) and survival we...
