The relation of serum thiol levels and thiol/disulphide homeostasis with the severity of coronary artery disease.

Background: The balance of oxidant and antioxidant status plays a key role in the coronary artery diseases (CAD). Thiol is one of the most important antioxidant barriers in humans, and thiol/disulphide homeostasis is a novel oxidative stress marker.

Aim: We aimed to investigate the relation of serum thiol levels and thiol/disulphide homeostasis with the presence and severity of CAD.

Long-term glucose insulin potassium infusion improves systolic and diastolic function in patients with chronic ischemic cardiomyopathy.

Unlabelled: We assessed the effects of glucose-insulin-potassium (GIK) using echocardiography, right ventricular catheterisation and myocardial scintigraphy with 99mTc sestamibi in stable patients with ischaemic cardiac dysfunction.

Methods: Thirty male patients with stable coronary disease (SCD) and an ejection fraction (EF) <40% were studied for systolic and diastolic function. Glucose 30%, 300 insulin units and KCl 6 g/l were infused at 1 ml/kg per hour for 24 hours.

Effect of nitric oxide inhibition on kidney function in experimental renovascular hypertension.

We examined the effect of acute systemic blockade of nitric oxide (NO) synthesis on blood pressure and renal function in rats with angiotensin II dependent two-kidney, one-clip Goldblatt hypertension. Hypertensive animals had significantly higher blood pressures, plasma NO metabolite concentrations and urinary NO metabolite excretion rates than control rats. Intravenous administration of N(G)-nitro-L-arginine methylester (L-NAME) (10 mg/kg) increased mean arterial pressure in both hypertensive and control animals with the magnitude of increase being greater in hypertensive than control rats (32 +/- 3 vs.

Effect of nitric oxide inhibition on blood pressure and renal function in TGR(mRen2)27 rats.

We examined the effect of acute systemic blockade of nitric oxide synthesis on blood pressure and renal function in the monogenetically hypertensive TGR(mRen2)27 rat strain. Untreated conscious transgenic rats had significantly (p < 0.01) higher systolic blood pressures (185 +/- 9 versus 130 +/- 5 mm Hg) and urinary albumin excretion (32 +/- 5 versus 6 +/- 2 mg/day) than did control animals without evidence of renal insufficiency.

Decreased urinary excretion of nitric oxide in acute rejection episodes in pediatric renal allograft recipients.

Acute renal allograft rejection continues to have a negative effect on graft survival despite a better understanding of the molecular basis of renal allograft rejection. Nitric oxide (NO) has important biological functions in cell defense and injury and some evidence exists that it may act as an immunomodulator in allograft transplantation. To determine if NO has any role in acute renal allograft rejection in pediatric patients, acute rejection episodes in pediatric renal transplant recipients were evaluated.
