... of the extracellular aminothiol redox state. The relative contributions of plasma total homocysteine (tHcy) and plasma total cysteine (tCys) to the total antioxidant capacity (TAOC) of plasma was established in subjects with normal and elevated plasma tHcy. A total of 10 subjects with severe hyperhomocysteinaemia (due...

... concentrations fell ( P = 0.03) and total cysteine concentrations rose significantly ( P = 0.048) after treatment for 2 weeks with vitamin B 12 injections. The magnitude of the mean fall in the fasting concentration of homocysteine (38.8 µ mol/l) was similar to the mean rise in cysteine levels (36.0 µ mol/l...

... an inflammatory challenge by intraperitoneal injection of tumour necrosis factor-α or endotoxin (lipopolysaccharide). 3. Diets containing 200 g of casein and 8 g of l-cysteine/kg (normal-protein diet), or 80 g of casein and 8 g of l-cysteine, or isonitrogenous amounts of l-methionine or l-alanine (low-protein...

...M. H. Davies; L. Klovrza; R. H. Waring; E. Elias 1. Fasting levels of plasma cysteine, plasma sulphate and the plasma cysteine/sulphate ratio were measured in patients with primary biliary cirrhosis and compared with those in patients with other liver disease, general intensive therapy unit...

.... For this purpose, we studied the effects of captopril (a thiol-containing angiotensin converting enzyme inhibitor), enalapril (an angiotensin converting enzyme inhibitor without a thiol group) and cysteine (a thiol-containing amino acid which has no angiotensin converting enzyme-inhibitory action) in adriamycin...
