Combined enzymatic and antioxidative treatment reduces ischemia-reperfusion injury in rabbit skeletal muscle.

Background: Ischemia/reperfusion (I/R) injury is characterized by the production of oxygen-free radicals leading to disturbances in vasomotility (microvascular constriction) and microvascular permeability (interstitial edema formation). The objective was to evaluate the effect of the combined antioxidative and enzymatic preparation Phlogenzym on I/R injury of skeletal muscle.

Materials And Methods: A rabbit hindlimb model of I/R (2.

Combined L-arginine and antioxidative vitamin treatment mollifies ischemia-reperfusion injury of skeletal muscle.

Enhanced production of superoxide in L-arginine-depleted environments and concomitant reduction of nitric oxide (NO) concentration are involved in ischemia-reperfusion (I/R) injury. Treatment with L-arginine or antioxidative vitamins alone and in combination was used to mollify I/R injury in skeletal muscle. Untreated rabbits were compared with those treated with L-arginine/antioxidative vitamin cocktail Omnibionta only, or a combination of L-arginine/ antioxidative vitamins during hind limb I/R (2.

Ischemia/reperfusion injury of skeletal muscle: plasma taurine as a measure of tissue damage.

Background: Cell membrane rupture by oxygen-derived free radicals is a systematic feature of ischemia/reperfusion (I/R) injury. High taurine concentration gradients in skeletal muscle prompted us to evaluate whether plasma taurine levels (pTau) are a useful marker of I/R injury after different periods of ischemia.

Methods: Rabbits were randomly assigned to either 1 or 2.

Influence of intravenous vitamin E supplementation in cardiac surgery on oxidative stress: a double-blinded, randomized, controlled study.

Background: I.V. infusions of vitamin E emulsion (all-rac-alpha-tocopherol) may reduce ischaemia-reperfusion injury after elective cardiac surgery.

Multivitamin administration before ischemia reduces ischemia-reperfusion injury in rabbit skeletal muscle.

This study investigated the effect of a multivitamin preparation administered before ischemia or before reperfusion, on ischemia-reperfusion (I/R) injury of skeletal muscle. An in vivo hindlimb skeletal muscle I/R model (2.5 h/2 h) was carried out on adult New Zealand white rabbits.
