Differential effects of inflammation models on rat T-kininogen and rat angiotensinogen.
The effect of different experimental models of inflammation on plasma concentrations of T-kininogen and angiotensinogen was examined in the rat. T-kininogen, a major phase protein which inhibits cysteine proteinase is increased in all cases of induced inflammation: administration of lipopolysaccharide and turpentine, bilateral nephrectomy or sham-operation and intraperitoneal injection of peanut oil. Angiotensinogen, the renin-substrate, is increased by lipopolysaccharide but is decreased by turpentine. Sham-operation or peanut oil injection have no effect on angiotensinogen whereas, bilateral nephrectomy and dexamethasone increase its concentration. Therefore, angiotensinogen is regulated differently than T-kininogen during inflammation.
