Automated determination of angiotensin-converting enzyme in serum.

Serum Angiotensin Converting Enzyme in Patients with Psoriasis

Background: Controversial data concerning the elevation of serum angiotensin-converting enzyme in psoriasis are reported in the literature. In order to verify whether this abnormality exists in Iranian patients, we performed this study. Method: Serum angiotensin-converting enzyme level was measured in 40 psoriatics. According to clinical forms of psoriasis, patients were further divided into th...

Study of Serum and Tissues Angiotensin Converting Enzyme (ACE) Activity in Rat with Gentamicin Induced Renal Toxicity

The angiotensin I-converting enzyme (ACE) converts the inactive angiotensin I molecule to the active angiotensin II. ACE is rich in epithelium, endothelium, and neuroepithelial cells and it found largely on the brush border of intestine and kidney proximal tubules. ACE also presents in the serum. Some pulmonary and renal toxic drugs change the serum and tissue ACE contents. In this research ACE...

P23: The Effects of Captopril, as Angiotensin Converting Enzyme Inhibitor, on LPS-Induced Systemic Inflammation

It has been shown that the renin-angiotensin system (RAS) plays key roles in the inflammation process. Imbalance in the oxidant-antioxidant system is one of the major causes of inflammation. In the present study, the effects of captopril on total and differential WBC, oxidative stress in systemic inflammation produced by lipopolysaccharide (LPS) were investigated. The rats were divided to: cont...

The spectrophotometric determination of human serum carboxypolypeptidase with angiotensin converting enzyme-like activity.

1. A colorimetric method was developed for the direct chemical assay of human carboxypeptidase A (carboxypolypeptidase; EC 3.4.12.2) with angiotensin converting enzyme-like activity in serum or plasma, with the substrate analogue glycyl-L-histidylglycine and the angiotensin converting enzyme substrate angiotensin I (A-I). This method was based on the spectrophototometric determination of histid...
